- the map scale is assumed to be a scale set in advance by the user.
- the control unit 20 acquires the user's degree of recognition as follows. With the function of the recognition degree acquisition module 21a, the control unit 20 acquires a recognition degree higher than the recognition degree for the first region as the recognition degree for the second region where the user's traffic frequency is higher than that of the first region.

- Route guidance is to guide the user so that the user can travel on a route that can reach the destination set by the user. During route guidance, it is unlikely that the user will consider the road section that will be traveled while looking at the map. Therefore, during route guidance, it is less necessary to display a detailed map in an area where the degree of user recognition is lower than when route guidance is not performed.
- the structure for performing route guidance is not specifically limited, What is necessary is just to employ

At this time, the control unit 20 draws the map at the initial scale S0 set by the user or the first to third scales S1 to S3 set by the function of the scale setting module 21b.
- the control unit 20 sets the scale of the map based on the user's degree of recognition for the currently passing area.
- the scale of the map that the user intends to see depends on the user's degree of recognition of the currently passing area. Therefore, by setting the scale of the map based on the user's degree of recognition with respect to the currently passing area, it is possible to reduce the possibility of setting a scale contrary to the user's intention.
- control part 20 can reduce possibility that the scale contrary to a user's intent will be set by setting a small scale as a map scale, so that the area where recognition is high.

- the scale of the map can be prevented from changing even if the road type changes. Therefore, in an area where the degree of recognition is “high”, it is possible to reduce the possibility that the user will be confused because the scale of the map changes to a large scale against the intention.
- the control unit 20 acquires a degree of recognition higher than the degree of recognition for the area not including the registration point as the degree of recognition for the area including the registration point registered by the user.

- the control unit 20 determines whether or not the road type of the passage road section has changed to a narrow street by the function of the recognition degree acquisition module 21a (step S120). That is, the control unit 20 determines whether or not the vehicle on which the user gets enters from a road section other than the narrow streets to the traffic road section of the narrow streets. In such a case, in principle, a detailed map showing the narrow streets should be displayed.
- step S120: Y the function of the scale setting module 21b determines whether the control unit 20 is performing route guidance (step S130). . That is, the control unit 20 determines whether or not a user traveling on a narrow street has a low need to consider a road section to be traveled while looking at a map.
- step S130 If it is determined that route guidance is being performed (step S130: Y), the control unit 20 changes the map scale to the third scale S3 by the function of the scale setting module 21b (step S140). Thereby, the map of the minimum scale on which a narrow street is displayed can be displayed in the state where it is low that a user needs to examine the road section from now on.
- step S130: N the control unit 20 determines whether or not the current location is around the home by the function of the recognition degree acquisition module 21a (step S150). That is, the control unit 20 determines whether or not the user's home as a registration point is included in the currently passing area (whether or not the degree of recognition is “high”).
- step S150: Y If it is determined that the current location is around the home (step S150: Y), the control unit 20 does not change the scale of the map by the function of the scale setting module 21b (step S160). That is, the control unit 20 maintains the initial scale S0 that is the scale of the map that was originally displayed. Thereby, it is possible to reduce the possibility that a map around the home where the user's recognition level is extremely high is displayed at a scale that is too detailed.
- step S150: N the function of the recognition degree acquisition module 21a causes the control unit 20 to determine whether or not the number of passages in the passage road section is equal to or greater than the first threshold N1. Determination is made (step S170). That is, the control unit 20 determines whether or not the traffic frequency of the currently passing area is high and the degree of recognition is “high”. When it determines with the frequency
- the control unit 20 uses the function of the scale setting module 21b to determine that the number of times of traffic on the road section is the second. It is determined whether or not the threshold value is N2 or more (step S180). That is, the control unit 20 determines whether or not the traffic frequency of the currently passing area is medium and the degree of recognition is “medium”.
- step S180: Y When it is determined that the number of times of traffic on the toll road section is equal to or greater than the second threshold N2 (step S180: Y), the control unit 20 changes the map scale to the first scale S1 by the function of the scale setting module 21b (step S180). S190). Thereby, when a user's recognition degree with respect to the area currently passing is medium, a detailed map can be displayed reasonably.
- control unit 20 changes the map scale to the second scale S2 by the function of the scale setting module 21b (Ste S200). As a result, a detailed map can be displayed when the user's awareness of the currently passing area is low.
- step S120: N If it is not determined that the road type of the road section has changed to a narrow street (step S120: N), the control unit 20 returns to step S120. That is, when the road type continues to pass through a road section other than the narrow street, the map of the initial scale S0 is continuously displayed.
- FIG. 2B and Table 2 are a graph and a table for explaining the scale of the map in the second embodiment.
- the scale after change when the road type of the road section has changed to a narrow street is determined in advance, but the scale after the change is multiplied by the change magnification to the initial scale S0 before the change. It may be set to a reduced scale.
- the map can be refined by changing the scale to a scale obtained by multiplying the initial scale S0 by a change magnification larger than 1.
- the control unit 20 uses the function of the scale setting module 21b so that when the user's degree of recognition for the currently passing area is within the second range, the degree of recognition is not within the second range.
- the change amount (change magnification) of the scale of the map to be changed according to the change of the route type of the route that the user is passing may be set small.

- the first change magnification K1 (for example, 3 times) is smaller than the second change magnification K2 (for example, 4 times).
- the function of the scale setting module 21b allows the control unit 20 to change the route type of the route on which the user is passing when the degree of recognition is within the third range than when the degree of recognition is not within the third range.
- the upper limit value or lower limit value of the map scale that can be changed may be set smaller.
- the scale obtained by multiplying the initial scale S0 by the first change magnification K1 and the second change magnification K2 may be too large. In order to prepare for such a case, an upper limit value of the scale may be determined.
- the control unit 20 sets the first scale S1 as the upper limit value of the scale.
- the control unit 20 sets the second scale S2 as the upper limit value of the scale. Similar to the first embodiment, the scale S1 is smaller than the scale S2.
- the control unit 20 The upper limit scales S1 and S2 are set as the scale. As described above, in areas where the degree of recognition is within the third range, by reducing the upper limit value of the scale of the map, it is possible to reduce the possibility that the user will be confused by displaying a more detailed map than intended.
- control unit 20 may set the amount of change when the map scale is reduced (when the map is widened) based on the user's degree of recognition of the currently passing area. For example, the control unit 20 may set the scale obtained by dividing the initial scale S0 by the change magnification as the scale after the change, and set the change magnification based on the user's recognition degree with respect to the currently passing area. Also good. Furthermore, the control unit 20 may set not only the upper limit value of the scale after the change but also the lower limit value. With the above configuration, it is possible to reduce the possibility that a map that is too wide against the user's intention is displayed. Furthermore, when changing the scale of the map according to the user's operation, the control unit 20 sets the amount of change in scale, the upper limit value, and the lower limit value based on the user's degree of recognition with respect to the currently passing area. May be.

- the recognition level set by the user for each region may be acquired, or the recognition level may be acquired based on a user profile or the like.
- the area that you are currently traveling may be the area that you are currently traveling, or the area that is within a certain distance from the point that you are currently traveling. It may include administrative divisions (prefectures, municipalities, etc.).
- the scale setting unit may set the scale of the map based on the degree of recognition, and may set the scale of the two-stage map based on at least the degree of recognition. Of course, the scale setting unit may continuously change the scale of the map according to the degree of recognition.
- the scale setting unit may set a smaller scale as the scale of the map in a region where the degree of recognition is higher. It is considered that the necessity of confirming a detailed map decreases as the user's awareness of the currently passing area increases. Therefore, by setting a smaller scale as a map scale for regions with higher recognition, the possibility of setting a scale contrary to the user's intention can be reduced.
- the scale setting unit may set a larger scale as the scale of the map in a region with higher recognition. Thereby, about a region with high recognition degree, a map can be displayed in detail and the map where a user can raise recognition degree more can be displayed. Further, the user may be configured to be able to switch between setting a smaller scale as a map scale for a region with higher recognition, or setting a larger scale as a map scale for a region with higher recognition. It may be configured to be switchable depending on the application. For example, the scale setting unit may set a smaller scale as a map scale in a region where the degree of recognition is higher in a map around the current location for navigation that is always displayed.

- the route may be any route that the user can pass through, and the moving means for moving on the route is not particularly limited.
- the scale setting unit may set a smaller scale as the scale of the map as the route type has a wider interval between the branch points. Thereby, a branch point can be displayed on a map, and the advancing direction in a branch point can be examined by looking at the map. Examples of branching points include intersections, interchanges, junctions, stations, ports and airports.
- the scale setting unit may not change the scale of the map even if the route type of the route that the user is passing changes when the degree of recognition is within the first range.
- the scale of the map can be prevented from changing even if the route type changes. Therefore, in areas where the degree of recognition is within the first range, the scale of the map changes to a large scale against the intention, or the scale of the map changes to a small scale, reducing the possibility of the user being confused it can.
- the scale setting unit changes the map when the degree of recognition is within the second range, according to the change in the route type of the route the user is traveling than when the degree of recognition is not within the second range.
- the amount of change in scale may be set small. That is, in a region where the degree of recognition is within the second range, by reducing the change amount of the map scale, it is possible to reduce the possibility that the user will be confused by the scale change (increase or decrease) much more than intended. .
- the scale setting unit can be changed when the degree of recognition is within the third range, according to a change in the route type of the route on which the user is traveling, compared to when the degree of recognition is not within the third range.
- the upper limit value or lower limit value of the map scale may be set smaller. In other words, in areas where the degree of recognition is within the third range, by reducing the upper limit value or lower limit value of the map scale, the possibility that the user will be confused by displaying a map that is more detailed or wider than intended is displayed. .
- the recognition degree acquisition unit may acquire a recognition degree higher than the recognition degree for the area not including the registration spot as the recognition degree for the area including the registration spot registered by the user.
- the registered spot is a spot registered by the user with some knowledge, it can be estimated that the degree of recognition of the area including the registered spot is high.
- the registration point may be the user's home. This is because it can be estimated that the area including the home is extremely recognized.
- the registration point is not limited to the user's home, but may be the user's work place or a point registered by the user by designating an arbitrary name.
- the recognition degree acquisition unit may acquire a recognition degree higher than the recognition degree for the first region as the recognition degree for the second region where the user's traffic frequency is higher than that of the first region. This is because it can be estimated that the higher the user's traffic frequency, the higher the degree of recognition.
- the traffic frequency may be a cumulative traffic count, or may be a traffic count per unit time or a traffic probability.
- the method of setting the scale of the map according to the user's degree of recognition for the region can be applied as a program or method.

Description
本発明は、地図表示システムおよび地図表示プログラムに関する。
The present invention relates to a map display system and a map display program.
走行中の道路が高速道路であるか細街路であるかに応じて地図の縮尺を設定する技術が知られている(特許文献1、参照。)。特許文献1において、ユーザが縮尺を変更する操作をしなくても、走行中の道路が高速道路であれば広域の地図が表示され、走行中の道路が細街路であれば詳細な地図が表示される。
A technique for setting the scale of a map depending on whether the road being traveled is an expressway or a narrow street is known (see Patent Document 1). In Patent Document 1, even if the user does not perform an operation of changing the scale, a wide-area map is displayed if the running road is a highway, and a detailed map is displayed if the running road is a narrow street. Is done.
しかしながら、特許文献1において、必ずしも走行中の道路が細街路であれば詳細な地図をユーザが見たいと考えるとは限らない。すなわち、単に高速道路であるか細街路であるかに応じて縮尺を変更すると、ユーザの意図に反して地図の縮尺が変更されてしまう場合が生じ得るという問題があった。
本発明は、前記課題にかんがみてなされたもので、ユーザの意図に反した縮尺が設定される可能性を低減できる技術を提供することを目的とする。 However, inPatent Document 1, if the road being traveled is a narrow street, the user does not always want to see a detailed map. That is, there is a problem that if the scale is simply changed depending on whether it is an expressway or a narrow street, the scale of the map may be changed against the user's intention.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of reducing the possibility of setting a scale contrary to the user's intention.
本発明は、前記課題にかんがみてなされたもので、ユーザの意図に反した縮尺が設定される可能性を低減できる技術を提供することを目的とする。 However, in
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of reducing the possibility of setting a scale contrary to the user's intention.
前記の目的を達成するため、本発明の地図表示システムは、現在通行している地域に対するユーザの認知度を取得する認知度取得部と、認知度に基づいて地図の縮尺を設定する縮尺設定部と、を備える。
In order to achieve the above object, a map display system of the present invention includes a recognition degree acquisition unit that acquires a user's recognition degree for a currently passing area, and a scale setting unit that sets a map scale based on the recognition degree. And comprising.
前記の目的を達成するため、本発明の地図表示プログラムは、コンピュータを、現在通行している地域に対するユーザの認知度を取得する認知度取得部、認知度に基づいて地図の縮尺を設定する縮尺設定部、として機能させる。
In order to achieve the above object, the map display program of the present invention uses a computer, a recognition degree acquisition unit for acquiring a user's recognition degree for a currently passing area, and a scale for setting a map scale based on the recognition degree. It functions as a setting unit.
前記の構成において、ユーザが見たいと意図する地図の縮尺は、現在通行している地域に対するユーザの認知度に依存する。そのため、現在通行している地域に対するユーザの認知度に基づいて地図の縮尺を設定することにより、ユーザの意図に反した縮尺が設定される可能性を低減できる。例えば、ユーザがよく知っている地域を通行しているのに詳細すぎる地図が表示されてユーザが戸惑う可能性を低減できる。逆に、ユーザがよく知らない地域なのに広域すぎる地図が表示されてユーザが戸惑う可能性を低減できる。
In the above configuration, the scale of the map that the user intends to see depends on the user's awareness of the currently passing area. Therefore, by setting the scale of the map based on the user's degree of recognition with respect to the currently passing area, it is possible to reduce the possibility of setting a scale contrary to the user's intention. For example, it is possible to reduce the possibility that the user will be confused by displaying a map that is too detailed even though the area is well known. On the contrary, it is possible to reduce the possibility that the user will be confused by displaying a map that is too wide although the area is not well known by the user.

The control unit 20 outputs a control signal to the touch panel display, and outputs an arbitrary image and sound including a map. Moreover, the control part 20 acquires a user's operation based on the touch operation with respect to a touchscreen display.
地図表示プログラム21は、認知度取得モジュール21aと縮尺設定モジュール21bと地図表示モジュール21cとを含む。認知度取得モジュール21aと縮尺設定モジュール21bとは、それぞれコンピュータとしての制御部20を認知度取得部と縮尺設定部として機能させるプログラムモジュールである。
The map display program 21 includes a recognition degree acquisition module 21a, a scale setting module 21b, and a map display module 21c. The recognition level acquisition module 21a and the scale setting module 21b are program modules that cause the control unit 20 as a computer to function as a recognition level acquisition unit and a scale setting unit, respectively.
認知度取得モジュール21aの機能により制御部20は、現在通行している地域に対するユーザの認知度を取得する。本実施形態において表示される地図は、現在通行している地域を表示する地図であり、現在地周辺の地図である。従って、地図に表示される地域と現在通行している地域とが同じであると見なすことができる。具体的に、地図において、現在地が常に基準位置に表示される。基準位置は、例えば地図の横方向に二等分する中央線上の位置であってもよい。地図は、地図の方向が車両の進行方向に依存するヘディングアップで表示されてもよいし、北を指す方向が固定されるノースアップで表示されてもよい。
The control unit 20 acquires the user's recognition degree for the currently passing area by the function of the recognition degree acquisition module 21a. The map displayed in the present embodiment is a map that displays a currently passing area, and is a map around the current location. Therefore, it can be considered that the area displayed on the map is the same as the area currently being passed. Specifically, the current location is always displayed at the reference position on the map. The reference position may be, for example, a position on the center line that bisects in the horizontal direction of the map. The map may be displayed with a heading up in which the direction of the map depends on the traveling direction of the vehicle, or may be displayed with a north up in which the direction pointing to the north is fixed.
なお、制御部20は、現在地が属する行政区画(市,区、郡,町,村)内に自宅が存在する場合に、現在通行している地域にユーザの自宅が含まれると判定してもよい。さらに、制御部20は、実際に地図に表示される領域内に自宅が存在する場合に、現在通行している地域にユーザの自宅が含まれると判定してもよい。本実施形態において、地図の縮尺は予めユーザが設定した縮尺となっていることとする。
Even if the control unit 20 has a home in the administrative division (city, ward, county, town, village) to which the current location belongs, the control unit 20 determines that the user's home is included in the currently passing area. Good. Furthermore, the control unit 20 may determine that the user's home is included in the currently passing area when the home is present in the area actually displayed on the map. In the present embodiment, the map scale is assumed to be a scale set in advance by the user.
一方、現在通行している地域に、登録地点としてのユーザの自宅が含まれない場合、制御部20は、以下のようにしてユーザの認知度を取得する。認知度取得モジュール21aの機能により制御部20は、ユーザの通行頻度が第1地域よりも高い第2地域に対する認知度として、第1地域に対する認知度よりも高い認知度を取得する。制御部20は、現在地が存在している道路区間(以下、通行道路区間)の通行回数を、現在通行している地域におけるユーザの通行頻度として取得する。そして、制御部20は、通行道路区間の通行回数が第1閾値N1(例えば4回)以上である場合に、現在通行している地域に対するユーザの認知度が『高』であると判定する。
On the other hand, when the user's home as a registration point is not included in the currently passing area, the control unit 20 acquires the user's degree of recognition as follows. With the function of the recognition degree acquisition module 21a, the control unit 20 acquires a recognition degree higher than the recognition degree for the first region as the recognition degree for the second region where the user's traffic frequency is higher than that of the first region. The control unit 20 acquires the number of times of traffic in a road section where the current location exists (hereinafter referred to as a “traffic road section”) as the user's traffic frequency in the currently passing area. And the control part 20 determines with the user's recognition degree with respect to the area currently passing is "high" when the frequency | count of a traffic road section is more than 1st threshold value N1 (for example, 4 times).
制御部20は、通行道路区間の通行回数が第1閾値N1未満かつ第2閾値N2(例えば2回)以上である場合に、現在通行している地域に対するユーザの認知度が『中』であると判定する。さらに、制御部20は、通行道路区間の通行回数が第2閾値N2未満である場合に、現在通行している地域に対するユーザの認知度が『低』であると判定する。なお、第2閾値N2は第1閾値N1よりも小さい。
The control unit 20 indicates that the user's degree of recognition with respect to the currently passing area is “medium” when the number of times of passage in the road section is less than the first threshold value N1 and greater than or equal to the second threshold value N2 (for example, twice). Is determined. Furthermore, the control part 20 determines with the user's recognition degree with respect to the area currently passing is "low" when the frequency | count of a traffic road area is less than 2nd threshold value N2. The second threshold N2 is smaller than the first threshold N1.
ここで、制御部20は、公知のマップマッチングによって通行道路区間を取得してもよい。また、制御部20は、通行履歴情報30cに基づいて通行道路区間の通行回数を取得する。具体的に、制御部20は、過去における車両の通行軌跡が通行道路区間を何回通過しているかをカウントすることにより、通行回数を取得する。なお、制御部20は、通行道路区間の通行回数として、通行道路区間と反対方向の道路区間(以下、対向車線)の通行回数を合算した回数を取得してもよいし、対向車線の通行回数を合算しない回数を取得してもよい。
Here, the control unit 20 may acquire a toll road section by known map matching. Moreover, the control part 20 acquires the frequency | count of a traffic road section based on the traffic history information 30c. Specifically, the control unit 20 acquires the number of times of traffic by counting how many times the vehicle trajectory in the past has passed through the traffic road section. In addition, the control part 20 may acquire the frequency | count which added together the frequency | count of the road area (henceforth, oncoming lane) of the opposite direction to a traffic road area as the frequency | count of a traffic road area, or the frequency | count of traffic of an oncoming lane. You may acquire the frequency | count which does not add.
縮尺設定モジュール21bの機能により制御部20は、現在通行している地域に対するユーザの認知度に基づいて地図の縮尺を設定する。具体的に、縮尺設定モジュール21bの機能により制御部20は、ユーザが通行中の路線の路線種別と、現在通行している地域に対するユーザの認知度との組み合わせに基づいて地図の縮尺を設定する。本実施形態において、制御部20は、原則的に、通行道路区間の道路種別が細街路以外から細街路に変化した場合に、地図の縮尺が増大するように地図の縮尺を設定する。細街路を通行するユーザは、細街路まで詳細に表示される地図を視認する必要があるからである。
The function of the scale setting module 21b causes the control unit 20 to set the scale of the map based on the user's degree of recognition for the currently passing area. Specifically, by the function of the scale setting module 21b, the control unit 20 sets the scale of the map based on the combination of the route type of the route that the user is passing and the user's degree of recognition with respect to the currently passing area. . In the present embodiment, in principle, the control unit 20 sets the map scale so that the map scale increases when the road type of the road section changes from a non-narrow street to a narrow street. This is because a user traveling on a narrow street needs to visually recognize a map displayed in detail up to the narrow street.
ただし、縮尺設定モジュール21bの機能により制御部20は、現在通行している地域に対するユーザの認知度が第1範囲内にある場合、ユーザが通行中の路線の路線種別が変化しても地図の縮尺を変化させないようにする。具体的に、制御部20は、現在通行している地域に対するユーザの認知度が『高』である場合に、通行道路区間の道路種別が細街路以外から細街路に変化しても地図の縮尺を変化させない。認知度が『高』であることは、認知度が第1範囲内であることを意味する。
However, the function of the scale setting module 21b allows the control unit 20 to display the map even if the route type of the route that the user is passing changes if the user's recognition degree for the currently passing region is within the first range. Do not change the scale. Specifically, the control unit 20 may reduce the scale of the map even if the road type of the passage road section changes from a non-narrow street to a narrow street when the user's recognition degree for the currently passing area is “high”. Do not change. That the degree of recognition is “high” means that the degree of recognition is within the first range.
制御部20は、通行道路区間の道路種別が細街路以外から細街路に変化する前の地図の縮尺(以下、初期縮尺S0)であった場合、通行道路区間の道路種別が細街路以外から細街路に変化しても地図の縮尺を初期縮尺S0のまま維持する。
When the road type of the road section is the scale of the map before the road type changes from a non-narrow street to a narrow street (hereinafter referred to as initial scale S0), the control unit 20 sets the road type of the road section from a non-narrow street. Even if it changes to a street, the scale of the map is maintained at the initial scale S0.
縮尺設定モジュール21bの機能により制御部20は、現在通行している地域に対するユーザの認知度が高い地域ほど地図の縮尺として小さい縮尺を設定する。具体的に、制御部20は、現在通行している地域に対するユーザの認知度が『中』である場合に、通行道路区間の道路種別が細街路以外から細街路に変化すると、地図の縮尺を初期縮尺S0から第1縮尺S1に変化させる。さらに、制御部20は、現在通行している地域に対するユーザの認知度が『低』である場合に、通行道路区間の道路種別が細街路以外から細街路に変化すると、地図の縮尺を初期縮尺S0から第2縮尺S2に変化させる。
By the function of the scale setting module 21b, the control unit 20 sets a smaller scale as a map scale in a region where the user's recognition degree with respect to the currently passing region is higher. Specifically, the control unit 20 changes the scale of the map when the road type of the passage road section changes from a non-narrow street to a narrow street when the user's recognition degree for the currently passing area is “medium”. The initial scale S0 is changed to the first scale S1. Further, the control unit 20 sets the map scale to the initial scale when the road type of the road section changes from a non-narrow street to a narrow street when the user's recognition degree for the currently passing area is “low”. Change from S0 to the second scale S2.
図2Aは、通行道路区間の道路種別が細街路以外から細街路に変化した際の縮尺を示すグラフである。図2Aにおいて、縮尺の変化を矢印で示す。図2Aに示すように、第1縮尺S1は、第2縮尺S2よりも小さい縮尺であり、第2縮尺S2よりも広域の地図を表示する縮尺である。従って、現在通行している地域に対するユーザの認知度が『中』である場合には、認知度が『低』である場合よりも広域の地図が表示されることとなる。
FIG. 2A is a graph showing the scale when the road type of the road section changes from a non-narrow street to a narrow street. In FIG. 2A, changes in scale are indicated by arrows. As shown in FIG. 2A, the first scale S1 is a scale smaller than the second scale S2, and is a scale that displays a map of a wider area than the second scale S2. Therefore, when the user's recognition degree for the currently passing area is “medium”, a wider area map is displayed than when the recognition degree is “low”.
なお、初期縮尺S0が第1縮尺S1や第2縮尺S2よりも大きい場合、制御部20は、現在通行している地域に対するユーザの認知度に拘わらず、地図の縮尺を初期縮尺S0のまま維持すればよい。初期縮尺S0はユーザが意図的に設定した縮尺であるため、ユーザの意図に反して詳細すぎる地図が表示されることとはならないからである。
When the initial scale S0 is larger than the first scale S1 and the second scale S2, the control unit 20 maintains the map scale at the initial scale S0 regardless of the user's awareness of the currently passing area. do it. This is because the initial scale S0 is a scale intentionally set by the user, so that a map that is too detailed against the user's intention is not displayed.
縮尺設定モジュール21bの機能により制御部20は、経路案内中において、通行道路区間の道路種別が細街路以外から細街路に変化した場合、地図の縮尺を初期縮尺S0から第3縮尺S3に変化させる。本実施形態において、第3縮尺S3は、第1縮尺S1と同じ大きさの縮尺であり、地図上において細街路が表示される最小の縮尺とされている。第2縮尺S2は、第1縮尺S1と第3縮尺S3の2倍の縮尺とされている。第1~第3縮尺S1~S3の具体的な大きさは、地図の表示サイズや描画方法に依存するため、特に限定されるものではない。
The function of the scale setting module 21b allows the control unit 20 to change the map scale from the initial scale S0 to the third scale S3 when the road type of the road section changes from a non-thin street to a narrow street during route guidance. . In the present embodiment, the third scale S3 is the same scale as the first scale S1, and is the smallest scale on which a narrow street is displayed on the map. The second scale S2 is twice as large as the first scale S1 and the third scale S3. The specific sizes of the first to third scales S1 to S3 are not particularly limited because they depend on the map display size and the drawing method.
経路案内とは、ユーザが設定した目的地まで到達可能な経路上をユーザが通行できるように、ユーザを誘導することである。経路案内中においては、これから通行する道路区間を、地図を見ながらユーザが検討する可能性が低い。そのため、経路案内中においては、経路案内を行っていない場合よりも、ユーザの認知度が低い地域において詳細な地図を表示する必要性が低いくなる。なお、経路案内を行うための構成は特に限定されず、公知の構成を採用すればよい。
Route guidance is to guide the user so that the user can travel on a route that can reach the destination set by the user. During route guidance, it is unlikely that the user will consider the road section that will be traveled while looking at the map. Therefore, during route guidance, it is less necessary to display a detailed map in an area where the degree of user recognition is lower than when route guidance is not performed. In addition, the structure for performing route guidance is not specifically limited, What is necessary is just to employ | adopt a well-known structure.
地図表示モジュール21cの機能により制御部20は、地図情報30aに基づいて地図を描画し、当該地図を示す画像データをユーザI/F部44に出力することにより、地図を表示する。このとき、制御部20は、ユーザによって設定された初期縮尺S0、または、縮尺設定モジュール21bの機能によって設定された第1~第3縮尺S1~S3で地図を描画する。
The control unit 20 displays a map by drawing a map based on the map information 30a and outputting image data indicating the map to the user I / F unit 44 by the function of the map display module 21c. At this time, the control unit 20 draws the map at the initial scale S0 set by the user or the first to third scales S1 to S3 set by the function of the scale setting module 21b.
以上説明した本実施形態において、制御部20は、現在通行している地域に対するユーザの認知度に基づいて地図の縮尺を設定する。ここで、ユーザが見たいと意図する地図の縮尺は、現在通行している地域に対するユーザの認知度に依存する。そのため、現在通行している地域に対するユーザの認知度に基づいて地図の縮尺を設定することにより、ユーザの意図に反した縮尺が設定される可能性を低減できる。
In the present embodiment described above, the control unit 20 sets the scale of the map based on the user's degree of recognition for the currently passing area. Here, the scale of the map that the user intends to see depends on the user's degree of recognition of the currently passing area. Therefore, by setting the scale of the map based on the user's degree of recognition with respect to the currently passing area, it is possible to reduce the possibility of setting a scale contrary to the user's intention.
ここで、現在通行している地域に対するユーザの認知度が高いほど、詳細な地図を確認する必要性が低下すると考えられる。従って、制御部20は、認知度が高い地域ほど地図の縮尺として小さい縮尺を設定することにより、ユーザの意図に反した縮尺が設定される可能性を低減できる。
Here, it is considered that the necessity of confirming a detailed map decreases as the user's awareness of the currently passing area increases. Therefore, the control part 20 can reduce possibility that the scale contrary to a user's intent will be set by setting a small scale as a map scale, so that the area where recognition is high.
また、制御部20は、ユーザが通行中の道路の道路種別と、現在通行している地域に対するユーザの認知度との組み合わせに基づいて地図の縮尺を設定する。これにより、ユーザが通行中の道路の道路種別と、現在通行している地域に対するユーザの認知度との組み合わせに基づいて最適な地図の縮尺を設定できる。
Also, the control unit 20 sets the scale of the map based on the combination of the road type of the road that the user is passing and the user's degree of recognition for the currently passing area. Thereby, the optimal map scale can be set based on the combination of the road type of the road on which the user is passing and the user's recognition level for the currently passing area.
また、制御部20は、現在通行している地域に対するユーザの認知度が『高』である場合、ユーザが通行中の道路区間の道路種別が変化しても地図の縮尺を初期縮尺S0から変化させない。これにより、認知度が『高』である地域においては、道路種別が変化しても地図の縮尺が変化しないようにすることができる。従って、認知度が『高』である地域において、意図に反して大縮尺へと地図の縮尺が変化してユーザが戸惑う可能性を低減できる。
In addition, when the user's degree of recognition for the currently passing area is “high”, the control unit 20 changes the scale of the map from the initial scale S0 even if the road type of the road section in which the user is passing changes. I won't let you. Thereby, in an area where the degree of recognition is “high”, the scale of the map can be prevented from changing even if the road type changes. Therefore, in an area where the degree of recognition is “high”, it is possible to reduce the possibility that the user will be confused because the scale of the map changes to a large scale against the intention.
制御部20は、ユーザが登録した登録地点を含む地域に対する認知度として、登録地点を含まない地域に対する認知度よりも高い認知度を取得する。ここで、登録地点は何らかの知識を持ってユーザが登録した地点であるため、登録地点を含む地域の認知度が高いと推定できる。具体的に、自宅を含む地域は認知度が極めて高いと推定できるため、制御部20は、自宅を含む地域に対する認知度として、自宅を含まない地域に対する認知度よりも高い認知度を取得することができる。また、ユーザの通行回数が多い地域ほど認知度が高いと推定できるため、制御部20は、ユーザの通行回数が第1地域よりも高い第2地域に対する認知度として、第1地域に対する認知度よりも高い認知度を取得できる。
The control unit 20 acquires a degree of recognition higher than the degree of recognition for the area not including the registration point as the degree of recognition for the area including the registration point registered by the user. Here, since the registered spot is a spot registered by the user with some knowledge, it can be estimated that the degree of recognition of the area including the registered spot is high. Specifically, since it can be estimated that the area including the home has a very high degree of recognition, the control unit 20 acquires, as the degree of recognition for the area including the home, higher than the degree of recognition for the area not including the home. Can do. Moreover, since it can be estimated that the recognition degree is higher in the region where the number of times the user has traveled, the control unit 20 is more than the recognition degree for the first region as the recognition degree for the second region where the user's number of traffic is higher than the first region. High recognition can be acquired.
(2)地図表示処理:
次に、地図表示プログラム21の機能により実行される地図表示処理を説明する。地図表示処理は、現在地周辺の地図を表示している期間に実行される処理である。まず、認知度取得モジュール21aの機能により制御部20は、登録地点情報30bと通行履歴情報30cとを取得する(ステップS100)。これにより、すなわち、制御部20は、登録地点としてユーザの自宅と、通行道路区間の通行回数とを取得可能となる。 (2) Map display processing:
Next, map display processing executed by the function of themap display program 21 will be described. The map display process is a process executed during a period in which a map around the current location is displayed. First, the control part 20 acquires the registration spot information 30b and the traffic history information 30c by the function of the recognition degree acquisition module 21a (step S100). Thus, in other words, the control unit 20 can acquire the user's home and the number of passes on the road section as registration points.
次に、地図表示プログラム21の機能により実行される地図表示処理を説明する。地図表示処理は、現在地周辺の地図を表示している期間に実行される処理である。まず、認知度取得モジュール21aの機能により制御部20は、登録地点情報30bと通行履歴情報30cとを取得する(ステップS100)。これにより、すなわち、制御部20は、登録地点としてユーザの自宅と、通行道路区間の通行回数とを取得可能となる。 (2) Map display processing:
Next, map display processing executed by the function of the
次に、認知度取得モジュール21aの機能により制御部20は、通行道路区間の路線種別を取得する(ステップS110)。すなわち、制御部20は、ユーザが現在通行している通行道路区間の路線種別として細街路または細街路以外のいずれかを取得する。次に、認知度取得モジュール21aの機能により制御部20は、通行道路区間の道路種別が細街路に変化したか否かを判定する(ステップS120)。すなわち、制御部20は、ユーザが乗車する車両が細街路以外の道路区間から細街路の通行道路区間へと進入したか否かを判定する。このような場合、原則的には、細街路まで表示される詳細な地図を表示するべきである。
Next, by the function of the recognition degree acquisition module 21a, the control unit 20 acquires the route type of the traffic road section (step S110). That is, the control unit 20 acquires either a narrow street or a route other than the narrow street as the route type of the road section that the user is currently passing. Next, the control unit 20 determines whether or not the road type of the passage road section has changed to a narrow street by the function of the recognition degree acquisition module 21a (step S120). That is, the control unit 20 determines whether or not the vehicle on which the user gets enters from a road section other than the narrow streets to the traffic road section of the narrow streets. In such a case, in principle, a detailed map showing the narrow streets should be displayed.
通行道路区間の道路種別が細街路に変化したと判定した場合(ステップS120:Y)、縮尺設定モジュール21bの機能により制御部20は、経路案内中であるか否かを判定する(ステップS130)。すなわち、制御部20は、細街路を通行中のユーザが、地図を見ながらこれから通行する道路区間を検討する必要性が低いか否かを判定する。
When it is determined that the road type of the toll road section has changed to a narrow street (step S120: Y), the function of the scale setting module 21b determines whether the control unit 20 is performing route guidance (step S130). . That is, the control unit 20 determines whether or not a user traveling on a narrow street has a low need to consider a road section to be traveled while looking at a map.
経路案内中であると判定した場合(ステップS130:Y)、縮尺設定モジュール21bの機能により制御部20は、地図の縮尺を第3縮尺S3に変更する(ステップS140)。これにより、これから通行する道路区間をユーザが検討する必要性が低い状態において、細街路が表示される最小の縮尺の地図を表示できる。
If it is determined that route guidance is being performed (step S130: Y), the control unit 20 changes the map scale to the third scale S3 by the function of the scale setting module 21b (step S140). Thereby, the map of the minimum scale on which a narrow street is displayed can be displayed in the state where it is low that a user needs to examine the road section from now on.
一方、経路案内中であると判定しなかった場合(ステップS130:N)、認知度取得モジュール21aの機能により制御部20は、現在地が自宅周辺であるか否かを判定する(ステップS150)。すなわち、制御部20は、現在通行している地域に、登録地点としてのユーザの自宅が含まれるか否か(認知度が『高』であるか否か)を判定する。
On the other hand, when it is not determined that route guidance is being performed (step S130: N), the control unit 20 determines whether or not the current location is around the home by the function of the recognition degree acquisition module 21a (step S150). That is, the control unit 20 determines whether or not the user's home as a registration point is included in the currently passing area (whether or not the degree of recognition is “high”).
現在地が自宅周辺であると判定した場合(ステップS150:Y)、縮尺設定モジュール21bの機能により制御部20は、地図の縮尺を変更しない(ステップS160)。すなわち、制御部20は、もともと表示していた地図の縮尺である初期縮尺S0を維持する。これにより、ユーザの認知度が極めて高い自宅周辺の地図が詳細すぎる縮尺で表示される可能性を低減できる。
If it is determined that the current location is around the home (step S150: Y), the control unit 20 does not change the scale of the map by the function of the scale setting module 21b (step S160). That is, the control unit 20 maintains the initial scale S0 that is the scale of the map that was originally displayed. Thereby, it is possible to reduce the possibility that a map around the home where the user's recognition level is extremely high is displayed at a scale that is too detailed.
現在地が自宅周辺であると判定しなかった場合(ステップS150:N)、認知度取得モジュール21aの機能により制御部20は、通行道路区間の通行回数が第1閾値N1以上であるか否かを判定する(ステップS170)。すなわち、制御部20は、現在通行している地域の通行頻度が高く、認知度が『高』であるか否かを判定する。通行道路区間の通行回数が第1閾値N1以上であると判定した場合(ステップS170:Y)、縮尺設定モジュール21bの機能により制御部20は、地図の縮尺を変更しない(ステップS160)。
When it is not determined that the current location is around the home (step S150: N), the function of the recognition degree acquisition module 21a causes the control unit 20 to determine whether or not the number of passages in the passage road section is equal to or greater than the first threshold N1. Determination is made (step S170). That is, the control unit 20 determines whether or not the traffic frequency of the currently passing area is high and the degree of recognition is “high”. When it determines with the frequency | count of a traffic road section being more than 1st threshold value N1 (step S170: Y), the control part 20 does not change the map scale by the function of the scale setting module 21b (step S160).
一方、通行道路区間の通行回数が第1閾値N1以上であると判定しなかった場合(ステップS170:N)、縮尺設定モジュール21bの機能により制御部20は、通行道路区間の通行回数が第2閾値N2以上であるか否かを判定する(ステップS180)。すなわち、制御部20は、現在通行している地域の通行頻度が中程度であり、認知度が『中』であるか否かを判定する。
On the other hand, when it is not determined that the number of times of traffic on the road section is equal to or greater than the first threshold N1 (step S170: N), the control unit 20 uses the function of the scale setting module 21b to determine that the number of times of traffic on the road section is the second. It is determined whether or not the threshold value is N2 or more (step S180). That is, the control unit 20 determines whether or not the traffic frequency of the currently passing area is medium and the degree of recognition is “medium”.
通行道路区間の通行回数が第2閾値N2以上であると判定した場合(ステップS180:Y)、縮尺設定モジュール21bの機能により制御部20は、地図の縮尺を第1縮尺S1に変更する(ステップS190)。これにより、現在通行している地域に対するユーザの認知度が中程度である場合に、ほどよく詳細な地図を表示することができる。
When it is determined that the number of times of traffic on the toll road section is equal to or greater than the second threshold N2 (step S180: Y), the control unit 20 changes the map scale to the first scale S1 by the function of the scale setting module 21b (step S180). S190). Thereby, when a user's recognition degree with respect to the area currently passing is medium, a detailed map can be displayed reasonably.
通行道路区間の通行回数が第2閾値N2以上であると判定なかった場合(ステップS180:N)、縮尺設定モジュール21bの機能により制御部20は、地図の縮尺を第2縮尺S2に変更する(ステップS200)。これにより、現在通行している地域に対するユーザの認知度が低い場合に、詳細な地図を表示することができる。
When it is not determined that the number of times of traffic on the toll road section is equal to or greater than the second threshold value N2 (step S180: N), the control unit 20 changes the map scale to the second scale S2 by the function of the scale setting module 21b ( Step S200). As a result, a detailed map can be displayed when the user's awareness of the currently passing area is low.
なお、通行道路区間の道路種別が細街路に変化したと判定しなかった場合(ステップS120:N)、制御部20は、ステップS120に戻る。すなわち、道路種別が細街路以外の通行道路区間を継続して通行する場合には、初期縮尺S0の地図を継続して表示する。
If it is not determined that the road type of the road section has changed to a narrow street (step S120: N), the control unit 20 returns to step S120. That is, when the road type continues to pass through a road section other than the narrow street, the map of the initial scale S0 is continuously displayed.
(3)第2実施形態:
図2Bおよび表2は第2実施形態における地図の縮尺を説明するグラフおよび表である。
第1実施形態においては、通行道路区間の道路種別が細街路へと変化した際における変更後の縮尺が予め決められていたが、変更後の縮尺が変更前の初期縮尺S0に変化倍率を乗算した大きさの縮尺に設定されてもよい。通行道路区間の道路種別が細街路へと変化した際に、初期縮尺S0に1よりも大きい変化倍率を乗算した縮尺に変化させることにより、地図を詳細化することができる。
(3) Second embodiment:
FIG. 2B and Table 2 are a graph and a table for explaining the scale of the map in the second embodiment.
In the first embodiment, the scale after change when the road type of the road section has changed to a narrow street is determined in advance, but the scale after the change is multiplied by the change magnification to the initial scale S0 before the change. It may be set to a reduced scale. When the road type of the road section changes to a narrow street, the map can be refined by changing the scale to a scale obtained by multiplying the initial scale S0 by a change magnification larger than 1.
図2Bおよび表2は第2実施形態における地図の縮尺を説明するグラフおよび表である。
FIG. 2B and Table 2 are a graph and a table for explaining the scale of the map in the second embodiment.
以上の構成において、縮尺設定モジュール21bの機能により制御部20は、現在通行している地域に対するユーザの認知度が第2範囲内にある場合、認知度が第2範囲内にない場合よりも、ユーザが通行中の路線の路線種別が変化したことに応じて変化させる地図の縮尺の変化量(変化倍率)を小さく設定してもよい。図2Bおよび表2に示すように、本実施形態において、通行道路区間の通行回数が第1閾値N1未満かつ第2閾値N2以上である場合に、認知度が『中』であることは、認知度が第2範囲内であることを意味する。また、通行道路区間の通行回数が第2閾値N2未満である場合に、認知度が『低』であることは、認知度が第2範囲外であることを意味する。
In the above configuration, the control unit 20 uses the function of the scale setting module 21b so that when the user's degree of recognition for the currently passing area is within the second range, the degree of recognition is not within the second range. The change amount (change magnification) of the scale of the map to be changed according to the change of the route type of the route that the user is passing may be set small. As shown in FIG. 2B and Table 2, in the present embodiment, it is recognized that the degree of recognition is “medium” when the number of passages in the road section is less than the first threshold N1 and greater than or equal to the second threshold N2. It means that the degree is within the second range. In addition, when the number of times of traffic on the toll road section is less than the second threshold value N2, that the degree of recognition is “low” means that the degree of recognition is outside the second range.
現在通行している地域に対するユーザの認知度が第2範囲内である場合、制御部20は、初期縮尺S0に第1変化倍率K1を乗算した縮尺を変化後の縮尺として設定する。一方、認知度が第2範囲外である場合、制御部20は、初期縮尺S0に第2変化倍率K2を乗算した縮尺を変化後の縮尺として設定する。ここで、第1変化倍率K1(例えば3倍)は、第2変化倍率K2(例えば4倍)よりも小さい。このように、認知度が第2範囲内にある地域において地図の縮尺の変化倍率を小さくすることにより、意図よりも大幅に縮尺が増大してユーザが戸惑う可能性を低減できる。
When the user's recognition degree for the currently passing area is within the second range, the control unit 20 sets a scale obtained by multiplying the initial scale S0 by the first change magnification K1 as the scale after the change. On the other hand, when the degree of recognition is outside the second range, the control unit 20 sets a scale obtained by multiplying the initial scale S0 by the second change magnification K2 as the scale after the change. Here, the first change magnification K1 (for example, 3 times) is smaller than the second change magnification K2 (for example, 4 times). In this way, by reducing the map scale change magnification in an area where the degree of recognition is within the second range, it is possible to reduce the possibility that the user will be confused because the scale is significantly larger than intended.
また、縮尺設定モジュール21bの機能により制御部20は、認知度が第3範囲内にある場合、認知度が第3範囲内にない場合よりも、ユーザが通行中の路線の路線種別が変化したことに応じて変化可能な地図の縮尺の上限値または下限値を小さく設定してもよい。図2Bおよび表2に示す例において、初期縮尺S0がもともと大きかった場合、初期縮尺S0に第1変化倍率K1や第2変化倍率K2を乗算した縮尺が大きくなりすぎる場合がある。このような場合に備えて縮尺の上限値が定められてもよい。
Further, the function of the scale setting module 21b allows the control unit 20 to change the route type of the route on which the user is passing when the degree of recognition is within the third range than when the degree of recognition is not within the third range. Depending on the situation, the upper limit value or lower limit value of the map scale that can be changed may be set smaller. In the example shown in FIG. 2B and Table 2, when the initial scale S0 is originally large, the scale obtained by multiplying the initial scale S0 by the first change magnification K1 and the second change magnification K2 may be too large. In order to prepare for such a case, an upper limit value of the scale may be determined.
本実施形態において、通行道路区間の通行回数が第1閾値N1未満かつ第2閾値N2以上である場合に、認知度が『中』であることは、認知度が第3範囲内であることを意味する。また、通行道路区間の通行回数が第2閾値N2未満である場合に、認知度が『低』であることは、認知度が第3範囲外であることを意味する。
In the present embodiment, when the number of times of passage in the toll road section is less than the first threshold value N1 and greater than or equal to the second threshold value N2, that the degree of recognition is “medium” means that the degree of recognition is within the third range. means. In addition, when the number of times of traffic on the toll road section is less than the second threshold value N2, that the degree of recognition is “low” means that the degree of recognition is outside the third range.
現在通行している地域に対するユーザの認知度が第3範囲内である場合、制御部20は、縮尺の上限値として第1縮尺S1を設定する。一方、認知度が第3範囲外である場合、制御部20は、縮尺の上限値として第2縮尺S2を設定する。第1実施形態と同様に、縮尺S1は縮尺S2よりも小さい。制御部20は、初期縮尺S0に第1変化倍率K1や第2変化倍率K2を乗算した変化後の縮尺S0*K1,S0*K2が上限値の縮尺S1,S2よりも大きくなる場合、地図の縮尺として上限値の縮尺S1,S2を設定する。このように、認知度が第3範囲内にある地域においては、地図の縮尺の上限値を小さくすることにより、意図よりも詳細な地図が表示されてユーザが戸惑う可能性を低減できる。
When the user's degree of recognition for the currently passing area is within the third range, the control unit 20 sets the first scale S1 as the upper limit value of the scale. On the other hand, when the degree of recognition is outside the third range, the control unit 20 sets the second scale S2 as the upper limit value of the scale. Similar to the first embodiment, the scale S1 is smaller than the scale S2. When the scale S0 * K1, S0 * K2 after the change obtained by multiplying the initial scale S0 by the first change magnification K1 or the second change magnification K2 is larger than the upper limit scales S1, S2, the control unit 20 The upper limit scales S1 and S2 are set as the scale. As described above, in areas where the degree of recognition is within the third range, by reducing the upper limit value of the scale of the map, it is possible to reduce the possibility that the user will be confused by displaying a more detailed map than intended.
さらに、制御部20は、地図の縮尺を減少させる際(地図を広域化させる際)における変化量を、現在通行している地域に対するユーザの認知度に基づいて設定してもよい。例えば、制御部20は、初期縮尺S0を変化倍率で除算した縮尺を変化後の縮尺として設定してもよく、この変化倍率を現在通行している地域に対するユーザの認知度に基づいて設定してもよい。さらに、制御部20は、変化後の縮尺の上限値だけでなく、下限値を設定してもよい。以上の構成により、ユーザの意図に反して広域すぎる地図が表示される可能性を低減できる。さらに、制御部20は、ユーザの操作に応じて地図の縮尺を変更する際に、現在通行している地域に対するユーザの認知度に基づいて、縮尺の変化量や上限値や下限値を設定してもよい。
Further, the control unit 20 may set the amount of change when the map scale is reduced (when the map is widened) based on the user's degree of recognition of the currently passing area. For example, the control unit 20 may set the scale obtained by dividing the initial scale S0 by the change magnification as the scale after the change, and set the change magnification based on the user's recognition degree with respect to the currently passing area. Also good. Furthermore, the control unit 20 may set not only the upper limit value of the scale after the change but also the lower limit value. With the above configuration, it is possible to reduce the possibility that a map that is too wide against the user's intention is displayed. Furthermore, when changing the scale of the map according to the user's operation, the control unit 20 sets the amount of change in scale, the upper limit value, and the lower limit value based on the user's degree of recognition with respect to the currently passing area. May be.
(4)他の実施形態:
第1実施形態において、通行道路区間の道路種別が細街路へと変化した際に縮尺を増大させる場合において、現在通行している地域に対するユーザの認知度を考慮する例を挙げたが、本発明はこの例に限定されるものではない。例えば、制御部20は、通行道路区間の道路種別が細街路以外へと変化した際に縮尺を減少させる場合において、現在通行している地域に対するユーザの認知度に基づいて縮尺を設定してもよい。これにより、ユーザの意図に反して広域すぎる地図が表示される可能性を低減できる。 (4) Other embodiments:
In the first embodiment, in the case where the scale is increased when the road type of the passage road section is changed to a narrow street, an example is given in which the user's awareness of the currently passing area is considered. Is not limited to this example. For example, in the case where the scale is reduced when the road type of the passage section changes to other than a narrow street, thecontrol unit 20 may set the scale based on the user's degree of recognition for the currently passing area. Good. Thereby, it is possible to reduce the possibility that a map that is too wide against the user's intention is displayed.

本発明において、地図表示システムは、地図を表示する機能を有する装置であればよく、地図を表示するディスプレイを制御可能な装置であればよい。従って、地図表示システムはディスプレイを備えていなくてもよく、ディスプレイに対して通信を介して表示データを送信する装置であってもよい。具体的に、地図表示システムは、スマートフォン等の携帯端末であってもよいし、パーソナルコンピュータであってもよいし、カーナビゲーションシステムであってもよいし、車両等の乗り物に内蔵された地図表示装置であってもよい。また、地図表示システムによって表示される地図の用途は特に限定されない。
In the present invention, the map display system may be a device having a function of displaying a map and may be a device capable of controlling a display for displaying a map. Therefore, the map display system may not include a display, and may be a device that transmits display data to the display via communication. Specifically, the map display system may be a mobile terminal such as a smartphone, a personal computer, a car navigation system, or a map display built in a vehicle such as a vehicle. It may be a device. Moreover, the use of the map displayed by the map display system is not particularly limited.
現在通行している地域に対するユーザの認知度とは、地図を視認するユーザ個人が認知している認知度であってもよいし、平均的なユーザが認知している認知度であってもよい。認知度取得部が認知度を取得する手法は種々考えられ、ユーザが地域ごとに設定した認知度を取得してもよいし、ユーザのプロファイル等に基づいて認知度を取得してもよい。現在通行している地域とは、実際に現在通行している領域であってもよいし、現在通行している地点から一定距離以内の領域であってもよいし、現在通行している地点を含む行政区画(都道府県市区町村等)であってもよい。
The user's degree of recognition with respect to the currently passing area may be a degree of recognition recognized by an individual user viewing the map, or may be a degree of recognition recognized by an average user. . There are various ways in which the recognition level acquisition unit acquires the recognition level. The recognition level set by the user for each region may be acquired, or the recognition level may be acquired based on a user profile or the like. The area that you are currently traveling may be the area that you are currently traveling, or the area that is within a certain distance from the point that you are currently traveling. It may include administrative divisions (prefectures, municipalities, etc.).
縮尺設定部は、認知度に基づいて地図の縮尺を設定すればよく、少なくとも認知度に基づいて2段階の地図の縮尺が設定されればよい。むろん、縮尺設定部は、認知度に応じて地図の縮尺を連続的に変化させてもよい。
The scale setting unit may set the scale of the map based on the degree of recognition, and may set the scale of the two-stage map based on at least the degree of recognition. Of course, the scale setting unit may continuously change the scale of the map according to the degree of recognition.
ここで、縮尺設定部は、認知度が高い地域ほど地図の縮尺として小さい縮尺を設定してもよい。現在通行している地域に対するユーザの認知度が高いほど、詳細な地図を確認する必要性が低下すると考えられる。従って、認知度が高い地域ほど地図の縮尺として小さい縮尺を設定することにより、ユーザの意図に反した縮尺が設定される可能性を低減できる。
Here, the scale setting unit may set a smaller scale as the scale of the map in a region where the degree of recognition is higher. It is considered that the necessity of confirming a detailed map decreases as the user's awareness of the currently passing area increases. Therefore, by setting a smaller scale as a map scale for regions with higher recognition, the possibility of setting a scale contrary to the user's intention can be reduced.
ただし、縮尺設定部は、認知度が高い地域ほど地図の縮尺として大きい縮尺を設定してもよい。これにより、認知度が高い地域については、より詳細に地図を表示することができ、ユーザがより認知度を高めることができる地図を表示することができる。さらに、認知度が高い地域ほど地図の縮尺として小さい縮尺を設定するのか、認知度が高い地域ほど地図の縮尺として大きい縮尺を設定するのかを、ユーザが切替可能に構成されてもよいし、地図の用途に応じて切替可能に構成されてもよい。例えば、縮尺設定部は、常時表示されるナビゲーション用の現在地周辺の地図において認知度が高い地域ほど地図の縮尺として小さい縮尺を設定してもよい。
However, the scale setting unit may set a larger scale as the scale of the map in a region with higher recognition. Thereby, about a region with high recognition degree, a map can be displayed in detail and the map where a user can raise recognition degree more can be displayed. Further, the user may be configured to be able to switch between setting a smaller scale as a map scale for a region with higher recognition, or setting a larger scale as a map scale for a region with higher recognition. It may be configured to be switchable depending on the application. For example, the scale setting unit may set a smaller scale as a map scale in a region where the degree of recognition is higher in a map around the current location for navigation that is always displayed.
また、地図はユーザが通行中の地域を表示する地図であり、縮尺設定部は、ユーザが通行中の路線の路線種別と認知度との組み合わせに基づいて地図の縮尺を設定してもよい。ユーザが通行中の路線の路線種別と、現在通行している地域に対するユーザの認知度との組み合わせに基づいて最適な地図の縮尺を設定できる。ここで、路線とは、ユーザが通行可能な路線であればよく、路線上を移動する移動手段は特に限定されない。縮尺設定部は、分岐点の間隔が広い路線種別であるほど、地図の縮尺として小さい縮尺を設定してもよい。これにより、分岐点が地図上に表示されるようにすることができ、地図を見て分岐点における進行方向を検討することができる。分岐点として、交差点やインターチェンジやジャンクションや駅や港や空港等が挙げられる。
Also, the map is a map that displays the area that the user is passing, and the scale setting unit may set the scale of the map based on the combination of the route type and the degree of recognition of the route that the user is passing. An optimal map scale can be set based on the combination of the route type of the route that the user is passing and the user's degree of recognition with respect to the currently passing region. Here, the route may be any route that the user can pass through, and the moving means for moving on the route is not particularly limited. The scale setting unit may set a smaller scale as the scale of the map as the route type has a wider interval between the branch points. Thereby, a branch point can be displayed on a map, and the advancing direction in a branch point can be examined by looking at the map. Examples of branching points include intersections, interchanges, junctions, stations, ports and airports.
また、縮尺設定部は、認知度が第1範囲内にある場合、ユーザが通行中の路線の路線種別が変化しても地図の縮尺を変化させないようにしてもよい。これにより、認知度が第1範囲内にある地域においては、路線種別が変化しても地図の縮尺が変化しないようにすることができる。従って、認知度が第1範囲内にある地域において、意図に反して大縮尺へと地図の縮尺が変化したり、小縮尺へと地図の縮尺が変化したりしてユーザが戸惑う可能性を低減できる。
Also, the scale setting unit may not change the scale of the map even if the route type of the route that the user is passing changes when the degree of recognition is within the first range. Thereby, in the area where the degree of recognition is within the first range, the scale of the map can be prevented from changing even if the route type changes. Therefore, in areas where the degree of recognition is within the first range, the scale of the map changes to a large scale against the intention, or the scale of the map changes to a small scale, reducing the possibility of the user being confused it can.
また、縮尺設定部は、認知度が第2範囲内にある場合、認知度が第2範囲内にない場合よりも、ユーザが通行中の路線の路線種別が変化したことに応じて変化させる地図の縮尺の変化量を小さく設定してもよい。すなわち、認知度が第2範囲内にある地域においては、地図の縮尺の変化量を小さくすることにより、意図よりも大幅に縮尺が変化(増大または減少)してユーザが戸惑う可能性を低減できる。
In addition, the scale setting unit changes the map when the degree of recognition is within the second range, according to the change in the route type of the route the user is traveling than when the degree of recognition is not within the second range. The amount of change in scale may be set small. That is, in a region where the degree of recognition is within the second range, by reducing the change amount of the map scale, it is possible to reduce the possibility that the user will be confused by the scale change (increase or decrease) much more than intended. .
また、縮尺設定部は、認知度が第3範囲内にある場合、認知度が第3範囲内にない場合よりも、ユーザが通行中の路線の路線種別が変化したことに応じて変化可能な地図の縮尺の上限値または下限値を小さく設定してもよい。すなわち、認知度が第3範囲内にある地域においては、地図の縮尺の上限値または下限値を小さくすることにより、意図よりも詳細または広域の地図が表示されてユーザが戸惑う可能性を低減できる。
In addition, the scale setting unit can be changed when the degree of recognition is within the third range, according to a change in the route type of the route on which the user is traveling, compared to when the degree of recognition is not within the third range. The upper limit value or lower limit value of the map scale may be set smaller. In other words, in areas where the degree of recognition is within the third range, by reducing the upper limit value or lower limit value of the map scale, the possibility that the user will be confused by displaying a map that is more detailed or wider than intended is displayed. .
また、認知度取得部は、ユーザが登録した登録地点を含む地域に対する認知度として、登録地点を含まない地域に対する認知度よりも高い認知度を取得してもよい。ここで、登録地点は何らかの知識を持ってユーザが登録した地点であるため、登録地点を含む地域の認知度が高いと推定できる。
Further, the recognition degree acquisition unit may acquire a recognition degree higher than the recognition degree for the area not including the registration spot as the recognition degree for the area including the registration spot registered by the user. Here, since the registered spot is a spot registered by the user with some knowledge, it can be estimated that the degree of recognition of the area including the registered spot is high.
より具体的に、登録地点はユーザの自宅であってもよい。自宅を含む地域は認知度が極めて高いと推定できるからである。ただし、登録地点はユーザの自宅に限らず、ユーザの勤務地であってもよいし、ユーザが任意の名称を指定して登録した地点であってもよい。
More specifically, the registration point may be the user's home. This is because it can be estimated that the area including the home is extremely recognized. However, the registration point is not limited to the user's home, but may be the user's work place or a point registered by the user by designating an arbitrary name.
さらに、認知度取得部は、ユーザの通行頻度が第1地域よりも高い第2地域に対する認知度として、第1地域に対する認知度よりも高い認知度を取得してもよい。ユーザの通行頻度が高い地域ほど認知度が高いと推定できるからである。通行頻度は、累積の通行回数であってもよいし、単位時間あたりの通行回数や通行確率であってもよい。
Furthermore, the recognition degree acquisition unit may acquire a recognition degree higher than the recognition degree for the first region as the recognition degree for the second region where the user's traffic frequency is higher than that of the first region. This is because it can be estimated that the higher the user's traffic frequency, the higher the degree of recognition. The traffic frequency may be a cumulative traffic count, or may be a traffic count per unit time or a traffic probability.
さらに、本発明のように、ユーザの地域に対する認知度に応じて地図の縮尺を設定する手法は、プログラムや方法としても適用可能である。また、以上のようなシステム、プログラム、方法は、単独の装置として実現される場合もあれば、車両に備えられる各部と共有の部品を利用して実現される場合もあり、各種の態様を含むものである。例えば、以上のような装置を備えたナビゲーションシステム、ナビゲーションシステムや方法、プログラムを提供することが可能である。また、一部がソフトウェアであり一部がハードウェアであったりするなど、適宜、変更可能である。さらに、装置を制御するプログラムの記録媒体としても発明は成立する。むろん、そのソフトウェアの記録媒体は、磁気記録媒体であってもよいし半導体メモリであってもよいし、今後開発されるいかなる記録媒体においても全く同様に考えることができる。
Furthermore, as in the present invention, the method of setting the scale of the map according to the user's degree of recognition for the region can be applied as a program or method. In addition, the system, program, and method as described above may be realized as a single device, or may be realized using components shared with each part of the vehicle, and include various aspects. It is a waste. For example, it is possible to provide a navigation system, a navigation system, a method, and a program that include the above devices. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention is also established as a recording medium for a program for controlling the apparatus. Of course, the software recording medium may be a magnetic recording medium, a semiconductor memory, or any recording medium that will be developed in the future.
