本発明の車両運転評価システムの一実施形態を、図面を用いて説明する。   An embodiment of a vehicle driving evaluation system of the present invention will be described with reference to the drawings.

図1に示すように、本実施形態の車両運転評価システム1は、道路地図データ31とナビゲーションプログラム32等を記憶する記憶部(道路地図データ記憶部)30と、ナビゲーションプログラム32を実行する主制御部10と、を備える車両用ナビゲーション装置として構成されており、設定される目的地までの経路を道路地図データに基づいて算出し、その経路を案内するナビゲーション機能を有する。   As shown in FIG. 1, the vehicle driving evaluation system 1 of this embodiment includes a storage unit (road map data storage unit) 30 that stores road map data 31 and a navigation program 32, and main control that executes the navigation program 32. And a navigation function for guiding the route by calculating a route to the set destination based on the road map data.

なお、道路地図データ31は、表示用の地図データと共に、交差点等の各種分岐点に対応するノードの位置情報や、ノードの接続を示すリンク情報の他、各ノードや各リンクに対応する付随情報(道路幅、車線数、等)の各種情報が含まれている。   In addition to the map data for display, the road map data 31 includes node position information corresponding to various branch points such as intersections, link information indicating node connections, and accompanying information corresponding to each node and each link. Various information (road width, number of lanes, etc.) is included.

主制御部10には、位置検出部11、加速度センサ12、速度センサ13、車両角速度センサ14、ウインカセンサ15、ブレーキセンサ16、運転者撮影カメラ22といった各種の運転挙動検出部100が接続され、さらに、地図表示や経路案内表示を映像出力する液晶ディスプレイ等の表示出力部2、スピーカ等の音声出力部3、音声入力のマイクやタッチパネル、リモコン、メカニカルスイッチ等を含む操作入力部4、データ等を外部出力する外部出力部5が接続されている。   The main controller 10 is connected to various driving behavior detectors 100 such as a position detector 11, an acceleration sensor 12, a speed sensor 13, a vehicle angular velocity sensor 14, a turn signal sensor 15, a brake sensor 16, and a driver photographing camera 22. Further, a display output unit 2 such as a liquid crystal display that outputs a map display or route guidance display, an audio output unit 3 such as a speaker, an operation input unit 4 including an audio input microphone or touch panel, a remote control, a mechanical switch, data, etc. Is connected to the external output unit 5.

なお、位置検出部11は、自車両の現在位置を特定するものであり、周知の地磁気センサ,ジャイロスコープ,距離センサの他,GPS衛星からの電波(GPS信号)に基づいて自車両の現在位置を検出するGPS受信機を有した周知のものである。主制御部10は、GPS受信機の受信信号や、他のセンサの検出情報に基づいて、自車両の現在位置及び進行方向を特定する現在位置特定手段及び進行方向特定手段として機能する。   The position detection unit 11 identifies the current position of the host vehicle. In addition to the known geomagnetic sensor, gyroscope, and distance sensor, the current position of the host vehicle is based on radio waves (GPS signals) from GPS satellites. It is a well-known one having a GPS receiver for detecting. The main control unit 10 functions as a current position specifying unit and a moving direction specifying unit that specify the current position and the traveling direction of the host vehicle based on the reception signal of the GPS receiver and the detection information of other sensors.

また、主制御部10には、車室内にて運転者の顔付近を撮影する運転者撮影カメラ22と、そのカメラ22の撮影画像から運転者の安全運転動作(特に安全確認動作)を検出する画像処理を行う画像処理部20が接続されている。   Further, the main control unit 10 detects a driver photographing camera 22 for photographing the vicinity of the driver's face in the passenger compartment and a driver's safe driving operation (especially a safety confirmation operation) from the captured image of the camera 22. An image processing unit 20 that performs image processing is connected.

また、画像処理部20は、運転者撮影カメラ22が撮像した画像データを受信及び処理することにより、ドライバの顔の動き(特にドライバの顔の向きの変化)を示す首振り情報と、ドライバの顔の目の開閉状態を示す開眼情報を、主制御部10に送信する。   In addition, the image processing unit 20 receives and processes image data captured by the driver photographing camera 22, thereby swinging information indicating the movement of the driver's face (particularly, the change in the driver's face direction) and the driver's face. Eye opening information indicating the open / closed state of the eyes of the face is transmitted to the main control unit 10.

ところで、本実施形態の主制御部10は、位置検出部11と道路地図データ31に基づいて、道路上の予め登録された一時停止地点への自車両の接近を特定し(一時停止地点接近特定手段)、接近した一時停止地点において、自車両の運転者が車両左方向と車両右方向の双方に顔を向ける首振動作(左向き動作と右向き動作)と、その首振動作の際の運転者の開眼状態を、画像処理部20の首振り情報と開眼情報に基づいて検出する(首振動作検出手段、開眼検出手段)。そして主制御部10は、首振動作と開眼状態の検出結果に基づいて、自車両が接近した当該一時停止地点における運転者の運転挙動を、例えば採点する形で評価・診断する(評価手段)。   By the way, the main control unit 10 of the present embodiment specifies the approach of the host vehicle to a pre-registered temporary stop point on the road based on the position detection unit 11 and the road map data 31 (temporary stop point approach specification). Means) at the approaching temporary stop point, the driver of the own vehicle turns his face in both the left direction and the right direction of the vehicle (left direction operation and right direction operation), and the driver during the swing operation Is detected based on the swing information and the eye opening information of the image processing unit 20 (swing motion detection means, eye opening detection means). Then, the main control unit 10 evaluates and diagnoses the driving behavior of the driver at the temporary stop point where the host vehicle is approaching based on the detection result of the swing motion and the open eye state, for example, in the form of scoring (evaluation means). .

以下、主制御部10が実行する一時停止地点における運転者の運転挙動評価処理を、図2及び図3を用いて説明する。   Hereinafter, the driving behavior evaluation process performed by the main control unit 10 at the temporary stop point will be described with reference to FIGS. 2 and 3.

まず主制御部10は、道路上の予め登録された一時停止地点(ここでは交差点)への自車両の接近を特定する(S1:一時停止地点接近特定手段)。登録された一時停止地点とは、道路地図データとして記憶されている一時停止地点のことである。ここでの主制御部10は、道路地図データ31の各一時停止地点の位置と、位置検出部11が検出する自車両の現在位置及び進行方向とに基づいて、自車両の進行方向に最も近い位置にある一時停止地点に対し所定距離以内に近づいた接近状態となったか否かを特定する。   First, the main control unit 10 specifies the approach of the host vehicle to a pre-registered temporary stop point (intersection here) on the road (S1: temporary stop point approach specifying means). The registered temporary stop point is a temporary stop point stored as road map data. The main control unit 10 here is closest to the traveling direction of the host vehicle based on the position of each temporary stop point of the road map data 31 and the current position and traveling direction of the host vehicle detected by the position detection unit 11. It is specified whether or not an approaching state has been approached within a predetermined distance with respect to the temporary stop point at the position.

一時停止地点への自車両の接近を特定すると(S1:Yes)、主制御部10は、運転者撮影カメラ22による撮影を開始する(S2)。   When the approach of the host vehicle to the temporary stop point is specified (S1: Yes), the main control unit 10 starts photographing with the driver photographing camera 22 (S2).

その後、主制御部10は、接近した一時停止地点からの自車両の離脱を特定する(S3:一時停止地点離脱特定手段)。ここでの主制御部10は、道路地図データ31の各一時停止地点の位置と、位置検出部11が検出する自車両の現在位置及び進行方向とに基づいて、接近対象であった一時停止地点を自車両が通過し、その一時停止地点に対し所定距離以上に離れた離間状態となったか否かを特定する。   Thereafter, the main control unit 10 specifies the departure of the host vehicle from the approaching temporary stop point (S3: temporary stop point departure specifying means). The main control unit 10 here is a temporary stop point that is an approach target based on the position of each temporary stop point of the road map data 31 and the current position and traveling direction of the host vehicle detected by the position detection unit 11. To determine whether or not the vehicle has passed through and is in a separated state that is more than a predetermined distance away from the temporary stop point.

一時停止地点からの自車両の離脱を特定すると(S3:Yes)、主制御部10は、運転者撮影カメラ22による撮影を終了し(S4)、その撮影画像に基づいて、一時停止地点通過時の運転者の挙動(運転挙動)に関する予め定められた項目について採点する(S5:評価手段)。   When the departure of the host vehicle from the temporary stop point is specified (S3: Yes), the main control unit 10 ends the photographing by the driver photographing camera 22 (S4), and when the temporary stopping point is passed based on the photographed image. A predetermined item related to the driver's behavior (driving behavior) is scored (S5: evaluation means).

ここでの項目は複数あって、それぞれの項目に予め定められた運転者の安全確認動作が定められている。主制御部10は、それら各動作を行ったか否かを集計して、その集計結果に基づいて点を決定する。ここでの運転者の安全確認動作は、図4に示すように、左右それぞれの方向への首振動作と、その首振動作時における所定時間以上(ここでは3秒以上)の開眼状態(目の開いた状態)の継続であり、それぞれの動作が行われたか否かに応じて、R1〜R8,L1〜L8のように採点され、点数(ポイント)が決定される。   There are a plurality of items here, and a driver's safety confirmation operation is predetermined for each item. The main control unit 10 aggregates whether or not each of these operations has been performed, and determines a point based on the aggregation result. As shown in FIG. 4, the driver's safety confirmation operation here includes a swinging motion in each of the left and right directions, and an eye open state (in this case, 3 seconds or longer) during the swinging motion (in this case, 3 seconds or longer). In accordance with whether or not each operation has been performed, the points are scored as R1 to R8 and L1 to L8, and the points (points) are determined.

具体的にいえば、主制御部10は、接近した一時停止地点において、自車両の運転者が車両左方向と車両右方向の双方に顔を向ける首振動作を検出するために、運転者の正面方向に対し所定の第一角度以上左又は右を向くサイドミラー目視首振動作(第一の左首振動作と第一の右首振動作)と、その第一角度よりも大となる所定の第二角度以上左又は右を向く後方目視首振動作(第二の左首振動作と第二の右首振動作)の有無をそれぞれ検出するとともに(首振動作検出手段)、その首振動作の際の運転者の開眼状態を検出するために、その首振動作中に所定時間を上回って開眼状態が継続されたか否かを検出する(開眼検出手段)。ここでは画像処理部20が、運転者撮影カメラ22による撮影画像を受信及び処理することにより、これら安全確認動作(左向き動作及び右向き動作と、開眼状態の所定時間以上の継続)の有無が特定される。そして、その特定結果を受信する主制御部10によって、今回の一時停止地点通過時の運転者の挙動に関する点数が、その特定結果に基づいて決定される。例えば、主制御部10は、サイドミラー目視首振動作と後方目視首振動作の双方がなされた場合を、それら双方のうちいずれか一方のみがなされた場合よりも高得点と評価し、それら双方がいずれもなされなかった場合を、それら双方のうちいずれか一方のみがなされた場合よりも低得点と評価することができるし、所定時間を上回って開眼状態が継続された場合を、所定時間を下回って開眼状態が継続された場合よりも高得点と評価することができる。ここでは、サイドミラー目視首振動作と、後方目視首振動作と、開眼状態の継続との3動作がそれぞれなされたか否かに応じて、図4に示す採点表に従い採点される。具体的にいえば、サイドミラー目視首振動作は、右左折方向側のサイドミラーに向かって顔を正対させる動作、後方目視首振動作は、右左折方向側の車両後席横の窓ガラス(窓ガラス越しの外の景色)を視認可能となる予め決められた後方目視方向(左右それぞれに異なる角度で定められる)に向かって顔を向ける動作、開眼状態の継続は、顔の長さと目の上下方向の見開き幅の比が一定以上となる開眼状態の3秒以上の継続として定められている。   More specifically, the main control unit 10 detects the driver's swinging motion in which the driver of the own vehicle turns his face in both the left direction and the right direction of the vehicle at the approaching temporary stop point. Side mirror visual swing motion (first left swing motion and first right swing motion) that faces left or right more than a predetermined first angle with respect to the front direction, and a predetermined greater than the first angle Detecting the presence or absence of backward visual swing motions (second left swing motion and second right swing motion) facing the left or right of the second angle or more (swing motion detection means) and the head vibration In order to detect the eye open state of the driver at the time of the operation, it is detected whether or not the eye open state is continued for a predetermined time during the swinging operation (eye open detecting means). Here, the presence or absence of these safety confirmation operations (leftward and rightward movements and continuation of the eye open state for a predetermined time or longer) is specified by the image processing unit 20 receiving and processing images captured by the driver photographing camera 22. The Then, the main control unit 10 that receives the identification result determines a score related to the behavior of the driver when passing the current temporary stop point based on the identification result. For example, the main control unit 10 evaluates a case where both the side mirror visual swing motion and the rear visual swing motion are performed as a higher score than when only one of them is performed, both of them. Can be evaluated as a lower score than when only one of them is made, and when the eye-opening state is continued beyond a predetermined time, It can be evaluated that the score is higher than when the eye-opening state continues below. Here, scoring is performed according to the scoring table shown in FIG. 4 depending on whether or not three operations of side mirror visual swing motion, rear visual swing motion, and continuation of the open eye state are performed. Specifically, the side mirror visual swing motion is an operation to face the face toward the side mirror on the right / left turn direction side, and the rear visual swing motion is a window glass next to the rear seat of the vehicle on the right / left turn direction side. The action of turning the face toward a predetermined rear viewing direction (determined at different angles on the left and right sides) that enables viewing of the scenery (outside the window glass), continuation of the open eye state, Is defined as a continuation of the eye-opening state in which the ratio of the spread widths in the vertical direction exceeds a certain value for 3 seconds or more.

続いて主制御部10は、その採点結果(評価結果)に基づいた報知情報を、表示出力部2又は音声出力部3のいずれか又は双方を含む報知出力部2,3から、運転者に向けて報知出力させる(S6:報知手段)。当該報知出力については、図3に示す処理を主制御部10が実行する形でなされる。   Subsequently, the main control unit 10 sends notification information based on the scoring result (evaluation result) from the notification output units 2 and 3 including either or both of the display output unit 2 and the voice output unit 3 to the driver. To output the notification (S6: notification means). The notification output is performed by the main control unit 10 executing the process shown in FIG.

即ち、まずは主制御部10が、S5で得られた採点結果(評価結果)が予め定められた通常得点範囲(通常ポイント範囲:ここでは)内であったか否かを判定する(S61)。   That is, first, the main control unit 10 determines whether or not the scoring result (evaluation result) obtained in S5 is within a predetermined normal scoring range (normal point range: here) (S61).

なお、通常得点範囲とは、多少の減点であれば許容されるような範囲であり、通常運転時になされたときに許容されるレベルの安全運転の範囲として定められる。ここでの通常得点範囲には最高得点が含まれており、(+1)〜(−1)の範囲として定められている。   Note that the normal scoring range is a range that is permissible if there is a slight deduction, and is defined as a safe driving range that is permissible when performed during normal operation. The normal score range here includes the highest score, and is defined as a range of (+1) to (−1).

通常得点範囲内であった場合は(S61:Yes)、本実施形態においては特別な報知をすることなく、本処理を終了する。通常得点範囲内においても予め決められた報知内容で報知出力を行うようにしてもよいが、頻繁に報知されて煩わしく感じる場合もあるため、ここでは控えている。   If it is within the normal score range (S61: Yes), the present process is terminated without any special notification in the present embodiment. Even within the normal scoring range, notification output may be performed with predetermined notification contents, but it is not shown here because it may be annoying because it is frequently notified.

S5で得られた採点結果(評価結果)が通常得点範囲(通常評価結果範囲)内でない場合(D61:No)、主制御部10は、S5で得られたその採点結果が上記通常得点範囲よりも低く定められた基準点(基準ポイント)より低いか否かを判定する(S62)。ここでの基準点は、(−3)以下と定められている。基準点よりも低いと判定された場合、主制御部10は、報知出力される内容として、一時停止に関する安全運転動作(特に安全確認動作)がなされていない旨を知らせる警告報知を決定する(S63)。警告報知の内容としては、今回の一時停止地点においてできていなかった一時停止に関する安全運転動作(特に安全確認動作)を具体的に指摘したり、そうした安全運転動作を行うよう促す等のアドバイスであってもよい。   When the scoring result (evaluation result) obtained in S5 is not within the normal scoring range (normal evaluation result range) (D61: No), the main control unit 10 determines that the scoring result obtained in S5 is higher than the normal scoring range. It is also determined whether the reference point is lower than the reference point (reference point) set low (S62). The reference point here is defined as (−3) or less. When it is determined that the value is lower than the reference point, the main control unit 10 determines the warning notification that informs that the safe driving operation (particularly the safety confirmation operation) related to the temporary stop is not performed as the content of the notification output (S63). ). The contents of the warning notification are advices such as specifically pointing out safe driving operations (especially safety confirmation operations) related to the temporary stop that were not made at this temporary stop point, and encouraging them to perform such a safe driving operation. May be.

次に主制御部10は、S5で得られた採点結果(評価結果)が、過去(ここでは過去一定期間を意味する)の平均得点(平均ポイント)よりも所定レベル以上低下したか否かを判定する(S64)。過去の平均得点よりも所定レベル以上低下した場合(S64:Yes)、主制御部10は、報知出力される内容として、運転者の注意力が一時的に低下している旨、ないしは注意力の低下解消を促す内容を決定する(S65)。例えば、休憩を促す内容とすることができる。ここでの所定レベル以上の低下とは、S5で得られた採点結果が過去の採点結果を平均した平均点に対して(−2)以下となる変化と定められている。   Next, the main control unit 10 determines whether or not the scoring result (evaluation result) obtained in S5 has decreased by a predetermined level or more than the average score (average point) of the past (which means a past fixed period here). Determine (S64). If the average score has decreased by a predetermined level or more than the past average score (S64: Yes), the main control unit 10 indicates that the driver's attention is temporarily reduced as the content of the notification output, or the attention The content for urging the reduction is determined (S65). For example, it can be a content that encourages a break. Here, the decrease above a predetermined level is defined as a change in which the scoring result obtained in S5 is (−2) or less with respect to the average score obtained by averaging past scoring results.

次に主制御部10は、S5で得られた採点結果(評価結果)が、過去の平均得点(平均ポイント)よりも所定レベル以上高くなったか否かを判定する(S66)。過去の平均得点よりも所定レベル以上高くなった場合(S66:Yes)、主制御部10は、報知出力される内容として、運転者に一時停止地点における安全運転技術(特に安全確認動作)が向上している旨の内容を決定する(S67)。ここでは、例えば、過去の平均得点(平均ポイント)よりも休憩を促す内容とすることができる。ここでは、S5で得られた採点結果が、過去の採点結果を平均した平均点よりも高かった場合を、所定レベル以上高くなったと判定するものとする。   Next, the main control unit 10 determines whether or not the scoring result (evaluation result) obtained in S5 is higher than the past average score (average point) by a predetermined level or more (S66). When it becomes higher than the past average score by a predetermined level or more (S66: Yes), the main control unit 10 improves the driver's safety driving technique (especially safety confirmation operation) at the temporary stop point as the content of the notification output. The content to the effect is determined (S67). Here, for example, the content may be a content that encourages a break rather than a past average score (average point). Here, when the scoring result obtained in S5 is higher than the average score obtained by averaging past scoring results, it is determined that the scoring result is higher than a predetermined level.

最後に主制御部10は、これまでの処理で決定された報知出力内容に基づいて最終的に報知出力する内容を決定し、その内容の報知を表示出力部2又は音声出力部3のいずれか又は双方に行わせる。仮に、複数種の内容が報知出力の内容として定められた場合には(例えばS63とS65の双方を報知する場合等)、それら複数種の内容を全て報知するようにする(警告報知手段、比較報知手段)。   Finally, the main control unit 10 determines the content to be finally notified based on the notification output content determined in the process so far, and the notification of the content is either the display output unit 2 or the audio output unit 3. Or let both sides do it. If a plurality of types of contents are determined as the contents of the notification output (for example, when both S63 and S65 are notified), all of the plurality of types of contents are notified (warning notification means, comparison) Notification means).

なお、上述における通常得点範囲や基準点、平均点、所定レベルといった予め定められた値については、記憶部30に記憶されており、主制御部10が必要なタイミングで適宜読み出して用いるものとする。   Note that the predetermined values such as the normal score range, the reference point, the average score, and the predetermined level described above are stored in the storage unit 30, and the main control unit 10 appropriately reads out and uses them at a necessary timing. .

図2に戻る。報知出力(S6)が終了すると、主制御部10は、運転者撮影カメラ22の撮影映像、さらに各運転挙動検出部100の検出情報、S5の採点結果(評価結果)を記憶部30に記憶する(S7:評価結果記憶手段)。そして、主制御部10は、イグニッションスイッチのOFFによって本処理を終了し、ONのままであれば再びS1に戻る。   Returning to FIG. When the notification output (S6) is completed, the main control unit 10 stores in the storage unit 30 the captured video of the driver imaging camera 22, the detection information of each driving behavior detection unit 100, and the scoring result (evaluation result) of S5. (S7: Evaluation result storage means). Then, the main control unit 10 ends this process by turning off the ignition switch, and returns to S1 again if it remains on.

本実施形態の車両運転評価システム1では、上記のように一時停止地点の通過時における運転者の安全確認動作のうち、左右の首振動作と開眼状況を組み合わせた形で採点(評価)している。ただし、採点項目(評価項目)はこれ以外にもあり、例えば一時停止に関していえば、一時停止地点接近時の緩やかな減速、一時停止地点での確実な停止、一時停止後の緩やかな加速、右左折の際のウインカー点灯、右左折の際の横加速度等の項目についても、主制御部10は、運転挙動検出部100の検出結果に基づいて採点を行って、各採点項目の採点結果(評価結果)を記憶部30に記憶している。   In the vehicle driving evaluation system 1 of the present embodiment, the driver's safety confirmation operation at the time of passing through the temporary stop point as described above is scored (evaluated) in the form of a combination of the left and right swinging motions and the eye-opening situation. Yes. However, there are other scoring items (evaluation items). For example, with regard to temporary stop, slow deceleration when approaching the temporary stop point, reliable stop at the temporary stop point, moderate acceleration after the temporary stop, right The main control unit 10 also scores items based on the detection results of the driving behavior detection unit 100 for items such as blinker lighting at the time of left turn and lateral acceleration at the time of right and left turn, and the scoring result (evaluation) of each scoring item Result) is stored in the storage unit 30.

そして、記憶部30に記憶される全ての採点結果(評価結果)は、外部出力部5から出力可能であり、例えば外部出力部5を介してメディア51と接続して、メディア51内に記憶してもよいし、外部出力部5を介して外部の管理装置52と接続して、管理装置52側の記憶部に記憶されてもよい。また、メディア51を介して管理装置52側の記憶部に記憶されてもよい。   All the scoring results (evaluation results) stored in the storage unit 30 can be output from the external output unit 5, for example, connected to the media 51 via the external output unit 5 and stored in the media 51. Alternatively, it may be connected to the external management device 52 via the external output unit 5 and stored in the storage unit on the management device 52 side. Further, it may be stored in the storage unit on the management device 52 side via the media 51.

管理装置52は、例えば図5のように、採点結果(評価結果)を統計的に処理してディスプレイ52a上に表示することができる(評価結果表示手段)。グラフ化して表示してもよい。   For example, as shown in FIG. 5, the management device 52 can statistically process the scoring results (evaluation results) and display them on the display 52a (evaluation result display means). A graph may be displayed.

以上、本発明の一実施形態を説明したが、これはあくまでも例示にすぎず、本発明はこれに限定されるものではなく、特許請求の範囲の趣旨を逸脱しない限りにおいて、当業者の知識に基づいて、追加及び省略等の種々の変更が可能である。   Although one embodiment of the present invention has been described above, this is merely an example, and the present invention is not limited to this, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications such as addition and omission can be made based on this.

以下、本発明の他の実施形態及び変形例について説明する。なお、上記実施形態と共通の機能部や同様の機能部については詳細な説明を省略する。また、上記実施形態と下記複数の変形例は、技術的な矛盾を生じない範囲において適宜組み合わせて実施できる。   Hereinafter, other embodiments and modifications of the present invention will be described. Note that detailed descriptions of functional units common to the above-described embodiment and similar functional units are omitted. In addition, the above-described embodiment and a plurality of modifications described below can be implemented in appropriate combination within a range that does not cause technical contradiction.

例えば、図2の処理におけるS1の一時停止地点の接近検出は、自車両の車外前方を撮影する車外前方撮影カメラ21の撮影画像に基づいて行うことができる。即ち、上記車外前方撮影カメラ21を主制御部10と接続する形で設けて、そのカメラ21が撮影した画像データを、画像処理部20が受信及び処理することにより、道路上の一時停止線の存在を検出し、さらに自車両の位置から当該一時停止線までの距離を例えば三角測量の原理を用いて主制御部10が算出して、算出距離を取得する。そして、その算出距離が所定距離以内となる場合を、道路上の一時停止地点に自車両が接近したと特定するようにしてもよい(S1:一時停止地点接近特定手段)。   For example, the approach detection of the temporary stop point in S1 in the process of FIG. 2 can be performed based on the captured image of the front-side camera 21 that captures the front outside the vehicle. That is, the above-mentioned front-facing camera 21 is connected to the main control unit 10 and the image data captured by the camera 21 is received and processed by the image processing unit 20 so that a temporary stop line on the road is displayed. The main control unit 10 detects the presence and further calculates the distance from the position of the host vehicle to the temporary stop line using, for example, the principle of triangulation, and acquires the calculated distance. Then, when the calculated distance is within a predetermined distance, the vehicle may be identified as approaching a temporary stop point on the road (S1: temporary stop point approach specifying unit).

なお、この場合の車外前方撮影カメラ21は、ドライブレコーダ210のカメラであり、撮影された画像は主制御部10を介して画像処理部20に送信するだけでなく、ドライブレコーダ210内の記憶部にも記憶・蓄積される。   In this case, the front-side camera 21 outside the vehicle is a camera of the drive recorder 210, and the captured image is not only transmitted to the image processing unit 20 via the main control unit 10, but also a storage unit in the drive recorder 210. Is also stored and accumulated.

上記実施形態において、主制御部10は、図2及び図3の処理により、記憶部(評価結果記憶部)30に記憶・蓄積されている過去の採点結果(評価結果)と、S5により評価された最新の採点結果(評価結果)とを比較する内容の報知情報を、運転者に報知出力している(比較報知手段)。具体的にいえば、S5により評価された最新の採点結果が過去の採点結果の平均値に対し、所定レベルを上回って良好である場合には、当該良好を示す旨の報知情報を運転者に報知出力し、所定レベルを下回って悪化した場合には、注意力の低下を認識させる内容の報知情報を運転者に報知出力している。   In the above embodiment, the main control unit 10 is evaluated by the past scoring results (evaluation results) stored and accumulated in the storage unit (evaluation result storage unit) 30 and S5 by the processes of FIGS. In addition, notification information having a content to be compared with the latest scoring result (evaluation result) is output to the driver (comparison notification means). Specifically, when the latest scoring result evaluated in S5 is better than a predetermined level with respect to the average value of the past scoring results, notification information indicating the goodness is given to the driver. When a notification is output and the condition is deteriorated below a predetermined level, notification information of a content for recognizing a decrease in attentiveness is output to the driver.

この構成において、主制御部10は、過去に通過した一時停止地点における採点結果の平均値(評価結果を平均化した平均評価情報)を記憶部30に記憶する必要がある。この場合、主制御部10は、予め定められた状況情報(例えば時刻・走行開始後の経過時間・位置情報等)を状況情報取得部(時計機能部やタイマー、位置検出部11等)23から取得する(状況情報取得手段)ために状況情報取得部23と接続して、S5により最新の採点結果を得た場合に、その最新の採点結果が、記憶部30に記憶・蓄積されている過去の採点結果の平均値に対し所定レベルを下回って悪化した注意力低下状態となったか否かを判定し、注意力低下状態となったと判定されたときには、状況情報取得部23が取得した状況情報を記憶部(状況情報記憶部)30に記憶・蓄積する(注意力低下状況記憶手段)ように構成できる。さらに、記憶・蓄積される状況情報に基づいて、注意力低下状態となる傾向の高い注意力低下状況を特定し(注意力低下状況特定手段)、状況情報取得部23が取得した状況情報が示す状況が注意力低下状況である場合、あるいは過去一定期間に所定レベル以上近づいた状況である場合に、注意力低下を注意喚起する内容の報知情報を、運転者に対し報知出力する(注意喚起出力手段)ように構成することもできる。   In this configuration, the main control unit 10 needs to store in the storage unit 30 the average value of the scoring results at the temporary stopping points that have passed in the past (average evaluation information obtained by averaging the evaluation results). In this case, the main control unit 10 obtains predetermined situation information (for example, time / elapsed time / position information after the start of traveling) from the situation information acquisition unit (clock function unit, timer, position detection unit 11, etc.) 23. In the past, the latest scoring result is stored / accumulated in the storage unit 30 when the latest scoring result is obtained in S5 by connecting to the situation information obtaining unit 23 for obtaining (situation information obtaining means) It is determined whether or not the attention level has deteriorated below a predetermined level with respect to the average value of the scoring results, and when it is determined that the attention level has decreased, the situation information acquired by the situation information acquisition unit 23 Can be stored and stored in the storage unit (situation information storage unit) 30 (attention level reduction state storage means). Further, based on the stored / accumulated situation information, the attention reduction state having a high tendency to become the attention reduction state is specified (attention reduction state specifying means), and the situation information acquired by the situation information acquisition unit 23 indicates If the situation is a situation where attention is reduced, or if the situation has approached a predetermined level or more in a certain period in the past, notification information that alerts the attention reduction is output to the driver (attention output) (Means) can also be configured.

例えば図6に示すように、主制御部10は、注意力低下状態となったと判定されたときに、状況情報として時刻と走行開始後の経過時間を記憶部30に記憶していくように構成するとともに、これを時間帯別と走行開始後の経過時間別の注意力低下状態の発生回数として集計し、その集計結果に基づいて、注意力低下状態となる傾向の高い時間帯と経過時間を特定する(注意力低下状況特定手段)ように構成する。そして、主制御部10は、状況情報取得部23が取得する時刻と経過時間が、注意力低下状態となる傾向の高い時間帯である場合や、注意力低下状態となる傾向の高い走行開始後の経過時間である場合に、注意力低下を注意喚起する内容の報知情報を、運転者に対し報知出力する(注意喚起出力手段)ように構成することもできる。また、この報知出力は、状況情報取得部23が取得する時刻と経過時間が、注意力低下状態となる傾向の高い時間帯や、注意力低下状態となる傾向の高い走行開始後の経過時間に対し所定レベル以上近づいた場合(例えば10分前等)に、注意力低下を注意喚起する内容の報知情報を、注意力低下を注意喚起する内容の報知情報を、運転者に対し報知出力する(注意喚起出力手段)ように構成することもできる。   For example, as shown in FIG. 6, the main control unit 10 is configured to store the time and the elapsed time after the start of traveling in the storage unit 30 as the situation information when it is determined that the state of attention is reduced. In addition, this is counted as the number of occurrences of reduced attention level by time zone and by elapsed time after the start of driving, and based on the totaled result, the time zone and elapsed time that tend to be low attention level are calculated. It is configured so as to be specified (attention level reduction status specifying means). Then, the main control unit 10 acquires the time and elapsed time acquired by the situation information acquisition unit 23 in a time zone in which there is a high tendency to be in a reduced attention level, or after the start of traveling that is likely to be in a reduced level of attention. In this case, it is also possible to configure so that the notification information of the content that alerts the attention reduction is output to the driver (attention output means). In addition, the notification output is generated at the time zone and the elapsed time acquired by the situation information acquisition unit 23 during a time zone where the attention level is likely to be low, or the elapsed time after the start of travel where the attention level is likely to be low. On the other hand, when approaching a predetermined level or more (for example, 10 minutes before, etc.), the notification information of the content that alerts the attention decrease and the notification information of the content that alerts the attention decrease are output to the driver ( It can also be configured as a warning output means).

また、上記実施形態において、運転者となるユーザーを設定する(ユーザー設定手段)ように構成してもよい。例えば、操作入力部4への所定操作により、登録ユーザーの中から運転者となるユーザーを選択するように構成できる。この場合、主制御部10は、記憶部30に記憶される採点結果(評価結果)は、運転者であるユーザーに対し対応付けて記憶させるようにして(評価結果記憶手段)、記憶部30に記憶されている採点結果のうち運転者として設定されたユーザーに対応する過去の評価内容と、S5で評価された最新の採点結果とを比較する内容の報知情報を、運転者に報知出力する(比較報知手段)ように構成できる。また、この場合、記憶部30に記憶されている採点結果は、ユーザーとの対応関係を特定可能であるから、外部出力部5から外部出力される採点結果もユーザーとの対応関係が特定可能な形で出力することができ、例えば管理装置52において、採点結果をディスプレイ52a上に表示する際には、ユーザー毎の採点結果を表示するようにできる(評価結果表示手段)。   Moreover, in the said embodiment, you may comprise so that the user who becomes a driver | operator may be set (user setting means). For example, a user who becomes a driver can be selected from registered users by a predetermined operation on the operation input unit 4. In this case, the main control unit 10 causes the scoring result (evaluation result) stored in the storage unit 30 to be stored in association with the user who is the driver (evaluation result storage unit). Of the stored scoring results, the past evaluation contents corresponding to the user set as the driver and the notification information of the contents for comparing the latest scoring results evaluated in S5 are output to the driver ( (Comparison notification means). In this case, since the scoring result stored in the storage unit 30 can specify the correspondence with the user, the scoring result output from the external output unit 5 can also specify the correspondence with the user. For example, when the scoring result is displayed on the display 52a in the management device 52, the scoring result for each user can be displayed (evaluation result display means).

なお、左首振動作(左向き動作)と、右首振動作(右向き動作)と、開眼状態の継続との3動作の定義は上記実施形態とは別に定められてもよい。また、開眼状態の継続については、左首振動作のときと、右首振動作のときと区別してもよい。例えば、左サイドミラー目視首振動作のときの開眼状態の継続が1.5秒以上、右サイドミラー目視首振動作のときの開眼状態の継続が1.5秒以上、左後方目視首振動作のときの開眼状態の継続が1.5秒以上、右後方目視首振動作のときの開眼状態の継続が1.5秒以上といった形で定められていてもよい。また、左首振動作と、右首振動作についても、顔の向く角度を上記実施形態とは別に定められてもよい。例えば、交差点手前の一時停止地点であれば、進行方向に対する交差点の交差道路の角度に応じた角度だけ、顔に左右に動かすと定めてもよい。   It should be noted that the definition of the three motions of the left swing motion (left motion), the right swing motion (right motion), and the continuation of the open eye state may be determined separately from the above embodiment. In addition, regarding the continuation of the eye-opened state, it may be distinguished from a left swing operation and a right swing operation. For example, when the left side mirror visual swing operation is continued for 1.5 seconds or more, when the right side mirror visual swing operation is continued for 1.5 seconds or more, the left rear visual swing operation The continuation of the eye-opening state at the time of の may be set to 1.5 seconds or more, and the continuation of the eye-opening state at the time of the right rear visual swinging operation may be set to 1.5 seconds or more. In addition, regarding the left swing motion and the right swing motion, the angle at which the face faces may be determined separately from the above embodiment. For example, if it is a temporary stop point before the intersection, it may be determined that the face is moved left and right by an angle corresponding to the angle of the intersection road of the intersection with respect to the traveling direction.

また、上記実施形態においては、右折時には車両右側への異なる2方向への首振動作(サイドミラー目視首振動作と後方目視首振動作)を評価し、左折時には車両左側への異なる2方向への首振動作(サイドミラー目視首振動作と後方目視首振動作)の有無を評価しているが、右折時に1方向ずつを評価するようにしてもよいし、あるいは、右折時には車両左側への首振動作を、左折時には車両右側への首振動作を評価することを加えるようにしてもよい。加える首振動作は、サイドミラー目視首振動作と後方目視首振動作のいずれか又は双方としてもよい。   Further, in the above-described embodiment, two different directions of swinging to the right side of the vehicle (side mirror visual swinging operation and rearward visual swinging operation) are evaluated when turning right, and in two different directions toward the left side of the vehicle when turning left. However, it is possible to evaluate one direction at a time when turning right, or to the left side of the vehicle when turning right The swinging motion may be evaluated by evaluating the swinging motion to the right side of the vehicle when turning left. The applied swing motion may be either or both of the side mirror visual swing motion and the rear visual swing motion.
