Fig. 5 ~ Fig. 7 is the process flow diagram of the process of the detection information system represented involved by present embodiment.Below first utilize the process of Fig. 5 to vehicle side system 101 to be described, afterwards, utilize the process of Tu6Ji Tu7Dui center side system 201 to be described.

In the step S1 shown in Fig. 5, position detection part 123 detects detection vehicle positional information (being coordinate position Pk) herein, and power part 113 detects detection information of vehicles.

In step s 2, control part 128 obtains detection vehicle positional information from position detection part 123.In addition, control part 128 obtains store car information by LAN114 in car etc. from information of vehicles storage part 111, and obtains detection information of vehicles from power part 113.Then, control part 128 generates detection information Fig. 2 ~ Fig. 4 shown according to the information got herein.

Next, the process of Tu6Ji Tu7Dui center side system 201 is utilized to be described.

First, in the step S11 shown in Fig. 6, central side acceptance division 231 receives the detection information from vehicle side system 101 directly or indirectly, and this detection information is supplied to detection DB server 213.Detection data storehouse server 213 stores providing the detection information come from side joint receipts portion, center 231 according to time series order.In addition, the VICS information etc. received by communication interface part 211 is supplied to infrastructure DB server 216 by infrastructure information input part 215, and facilities information based on this VICS information etc. stores by infrastructure DB server 216.

In step S12, traffic presumption unit 217 carries out based on the detection information carrying out storing according to time series order in step s 11 the presumption transmitting traffic.

Fig. 7 is the figure of the presumption process representing the transmission traffic of being undertaken by traffic presumption unit 217 in step s 12.By a series of process shown in this Fig. 7, traffic presumption unit 217 suppresses driving mode information based on the detection vehicle positional information comprised in the detection information received by central side acceptance division 213, driving type information, detection vehicle velocity information and power consumption, estimates and drives operable type to sail speed.Below, Fig. 7 is utilized to be described in detail to this presumption process.

First, in the step s 21, traffic presumption unit 217, from the detection information (detection information received by central side acceptance division 231) be stored in detection DB server 213, obtains the detection information relevant with a road (position) of presumption object.In addition, herein for the purpose of simplifying the description, set and obtain a detection information by traffic presumption unit 217.Traffic presumption unit 217, from accessed detection information, obtains and drives type information, detection vehicle velocity information and power consumption to suppress driving mode information.

In step S22, traffic presumption unit 217 judges that the driving type information got in the step s 21 represents PHEV type of drive (HEV type of drive) or represents EV type of drive.When driving type information neither to represent that PHEV type of drive (HEV type of drive) does not represent EV type of drive yet (situation herein for driving type information to represent engine driving mode), advance to step S23, when driving type information to represent a certain mode in PHEV type of drive (HEV type of drive) or EV type of drive, advance to step S24.

In step S23, the wheeled speed (being also denoted as below as " Veng ") of the engine driving mode in presumption object road is estimated as the speed v shown in detection vehicle velocity information got in step S21 by traffic presumption unit 217.

Wherein, when the speed of detection vehicle 151 exceedes statutory restrictions speed to travel, from the viewpoint observing regulation, wheeled speed Veng should be estimated as the speed v of detection vehicle 151.Therefore, wheeled speed Veng is estimated as one less in speed v represented by detection vehicle velocity information and maximum speed limit by the traffic presumption unit 217 involved by present embodiment.(maximum speed limit is exactly v) represent this meaning to Veng=Min shown in Fig. 7.In addition, for maximum speed limit herein, to be used in map datum in advance with maximum speed limit corresponding with presumption object road in the maximum speed limit that each road stores one to one.Afterwards, a series of process as shown in Figure 7 terminates.

In step S24, traffic presumption unit 217 suppresses driving mode information based on the power consumption got in step S21, judges that power consumption suppresses driving mode to be open or close.When power consumption suppresses driving mode to be opened, advance to step S25, when power consumption suppresses driving mode to be closed, advance to step S26.

Herein, when judging that power consumption suppresses driving mode to be opened by step S24, to suppress energy consumption to have precedence over travel speed to travel, therefore, although think that in fact road is more empty, the possibility do not travelled with speed high is as far as possible larger.Therefore, think and to surmount the detection vehicle 151 that power consumption suppresses driving mode to be opened on this road, and the possibility that can travel with the speed more than speed v shown in this detection vehicle velocity information is larger.

Therefore, in step s 25, the wheeled speed (being also denoted as below " Vphev ") of PHEV type of drive in presumption object road is estimated as more than the speed v shown in detection vehicle velocity information to traffic presumption unit 217 and value below maximum speed limit and f1 (maximum speed limit, v).Equally, in step s 25, the wheeled speed (being also denoted as below " Vev ") of EV type of drive in presumption object road is estimated as more than the speed v shown in detection vehicle velocity information to traffic presumption unit 217 and value below maximum speed limit and f2 (maximum speed limit, v).

Herein, f1 (maximum speed limit, v) and f2 (maximum speed limit, v) is the function of maximum speed limit and speed v, if get more than speed v and value below maximum speed limit, then can be arbitrary function.Such as, also can be f1 (maximum speed limit, v)=maximum speed limit, and f2 (maximum speed limit, v)=maximum speed limit, or also can be f1 (maximum speed limit, v)=min (maximum speed limit, (maximum speed limit+v)/2), and f2 (maximum speed limit, v)=min (maximum speed limit, (maximum speed limit+v)/2).In below illustrating, with f1 (maximum speed limit, v)=min (maximum speed limit, (maximum speed limit+v)/2), and f2 (maximum speed limit, the situation of v)=min (maximum speed limit, (maximum speed limit+v)/2) is described.Afterwards, a series of process as shown in Figure 7 terminates.

In addition, when judging that power consumption suppresses driving mode to be closed by step S24, think that the driver of detection vehicle 151 is just with speeds high as far as possible.That is, think on this road, about the travel speed of vehicle only can be increased to the same uniform velocity of the detection vehicle 151 that power consumption suppresses driving mode to be closed.

Therefore, in step S26, the wheeled velocities Vp hev of the PHEV type of drive estimated in object road (position) is estimated as Min (maximum speed limit by traffic presumption unit 217, v), the wheeled speed Vev of EV type of drive is estimated as Min (maximum speed limit, v).Afterwards, a series of process as shown in Figure 7 terminates.

Above, be illustrated being estimated the process driving operable type to sail speed by traffic presumption unit 217.In addition, in the above description, in step S21, a detection information is obtained by traffic presumption unit 217.But, in the step s 21, when traffic presumption unit 217 drives type (drives type information) to obtain multiple detection vehicle velocity information for one, the statistical value of the speed v shown in multiple detection vehicle velocity information (such as mean value or maximal value) also can be used to replace above-mentioned speed v.

Get back to Fig. 6, after the process of step S12 terminates, in step s 13, traffic presumption unit 217 is sailed speed (transmission traffic) to driving operable type and is revised.Such as, suppose when adopt can from infrastructure information get drive operable type to sail the structure of speed, drive operable type to sail speed, compare with the driving operable type speed of sailing to deduce in step s 12 by getting from this infrastructure information.When both differences are more than defined threshold, traffic presumption unit 217 can reduce these and drive operable type to sail the fiduciary level of speed, or one that only makes these drive operable type to sail in speed effective, or both mean value is sailed speed as revised driving operable type.Or, when the speed of detection vehicle 151 of PHEV type of drive (HEV type of drive) or EV type of drive can only be got, also can using the wheeled type speed that gets from the infrastructure information wheeled speed as engine driving mode.

In step S14, traffic presumption unit 217 sails transmission traffic storage (preservation) of speed to traffic DB server 218 by comprising through revised driving operable type.Then, the transmission traffic be stored in traffic DB server 218 is sent to the outsides such as each vehicle by central side sending part 232.

Vehicle side system 101 involved by present embodiment as above and central side system 201, deduce and drive operable type to sail speed, and this driving operable type speed of sailing is sent to each vehicle.Herein, it has been generally acknowledged that the wheeled speed that not there is power consumption and suppress the wheeled speed of vehicle (such as engine vehicle) of driving mode to be greater than to there is power consumption and suppress the vehicle (such as PHEV) of driving mode, and closer to the wheeled speed of reality.According to the present embodiment, each vehicle can obtain the wheeled speed not having power consumption and suppress the vehicle (such as engine vehicle) of driving mode, to sail speed as driving operable type, therefore can improve the reliability of the wheeled speed deduced, and then improve the reliability of detection information system.Herein, the wheeled speed of the vehicle (herein for engine vehicle) of driving mode is suppressed to be low speed once in a while not having power consumption, and have power consumption suppress the wheeled speed of vehicle (such as PHEV) of driving mode be at a high speed when, think that having power consumption suppresses the wheeled speed of the vehicle (such as PHEV) of driving mode compared with the wheeled speed close to reality.According to the present embodiment, each vehicle can obtain the wheeled speed having power consumption and suppress the vehicle (such as PHEV) of driving mode, to sail speed as driving operable type, therefore can improve the reliability of the wheeled speed deduced, and then improve the reliability of detection information system.

In addition, in present embodiment, traffic presumption unit 217 suppresses driving mode information to estimate traffic (driving operable type to sail speed) based on power consumption., it has been generally acknowledged that the wheeled speed of vehicle that power consumption suppresses driving mode to be closed is greater than the wheeled speed of the vehicle that power consumption suppresses driving mode to be opened herein, and closer to the wheeled speed of reality.Therefore, according to the present embodiment, even if when each vehicle can only obtain the wheeled speed of the vehicle (being engine vehicle) without power consumption suppression driving mode herein, still can get the wheeled speed of the vehicle that power consumption suppresses driving mode to be closed, therefore can improve the reliability of the wheeled speed deduced, and then the reliability of detection information system can be improved.

In addition, in the above description, when traffic presumption unit 217 power consumption suppresses driving mode information all cannot obtain, can be estimated by the some steps in step S25 and S26 and drive operable type to sail speed, and lower reliability based distribution is sailed speed to this driving operable type, thus this fiduciary level is included in transmission traffic in send.

(variation 2 of embodiment 1)

In the variation 2 of embodiment 1, central side system 201 estimates the congestion information (being also denoted as below " supply congestion information ") relevant with the charging (energy recharge) of charging station (energy recharge station).

Fig. 9 represents in above-mentioned steps S12, the figure of the presumption process of the transmission traffic that the traffic presumption unit 217 involved by this variation is carried out.In a series of process shown in this Fig. 9, traffic presumption unit 217, based on the position at the detection vehicle positional information received by central side acceptance division 231 and energy recharge station, deduces the congestion information relevant to the energy recharge at energy recharge station for each driving type.Below, Fig. 9 is utilized to be described in detail to this presumption process.

According to above-mentioned variation, each vehicle can obtain the congestion information relevant to energy recharge.Therefore, each vehicle can accept energy recharge at the energy recharge station do not blocked up.

In addition, in a series of process shown in Fig. 9, supply congestion information is deduced to PHEV (HEV), EV, but also can deduce supply congestion information similarly to engine vehicle.In addition, when vehicle is PHEV (HEV), the EV generating above-mentioned charging plan, also energy recharge plan can be changed based on the supply congestion information from central side system 201, long as much as possible with the distance making to utilize gasoline to travel before arriving the charging station that do not get congestion.

(variation 3 of embodiment 1)

In the variation 3 of embodiment 1, central side system 201 estimates the congestion information (supply congestion information) relevant with the charging (energy recharge) of charging station (energy recharge station).

Figure 10 represents in above-mentioned steps S12, the figure of the presumption process of the transmission traffic that the traffic presumption unit 217 involved by this variation is carried out.In a series of process shown in this Figure 10, the driving operable type of multiple driving types that traffic presumption unit 217 deduces based on itself sails speed, deduces the congestion information (supply congestion information) relevant to the energy recharge at energy recharge station.Below, Figure 10 is utilized to be described in detail to this presumption process.

As shown in Figure 10, traffic presumption unit 217 carries out process same as described above in step S21 ~ S27.Then, after step S27, in step S31, traffic presumption unit 217 judges whether to set and estimates supply congestion information.When set supply congestion information is estimated, advance to step S32, when do not set supply congestion information is estimated, a series of process shown in Figure 10 terminates.

In step s 32, traffic presumption unit 217 is according to the wheeled speed Vev of the wheeled speed Veng of the engine driving mode up to the present got, the wheeled velocities Vp hev of PHEV type of drive and EV type of drive, judge it is Vphev < g1 (Veng), or Vev < g2 (Veng).G1 (Veng), g2 (Veng) are the functions of Veng, are described with the situation of g1 (Veng)=Veng/5, g2 (Veng)=Veng/5 herein.

When being judged as Veng < g1 (Veng) in step s 32, advance to step S33, traffic presumption unit 217 generates supply congestion information, and this supply congestion information represents that charging station on the road that the driving operable type used herein is sailed corresponding to speed (Vphev) or refuelling station there occurs charging and block up or refuel and block up.Afterwards, a series of process as shown in Figure 10 terminates.On the other hand, when being judged as Vphev >=g1 (Veng) in step s 32, advance to step S34, traffic presumption unit 217 generates supply congestion information, and this supply congestion information represents that charging station on the road that the driving operable type used herein is sailed corresponding to speed (Vphev) or refuelling station charging do not occur and block up or refuel and block up.Afterwards, a series of process as shown in Figure 10 terminates.

Similarly, when being judged as Veng < g1 (Veng) in step s 32, advance to step S33, traffic presumption unit 217 generates supply congestion information, and this supply congestion information represents that the charging station on the road that the driving operable type used herein is sailed corresponding to speed (Vev) there occurs charging and blocks up.Afterwards, a series of process as shown in Figure 10 terminates.On the other hand, when being judged as Vev >=g1 (Veng) in step s 32, advance to step S34, traffic presumption unit 217 generates supply congestion information, and this supply congestion information represents that the charging station on the road that the driving operable type used herein is sailed corresponding to speed (Vev) charging does not occur and blocks up.Afterwards, a series of process as shown in Figure 10 terminates.

In addition, in the above description, Vphev etc. is compared with the functional value of Veng, and judge whether that there occurs supply blocks up.But be not limited thereto, also Vphev etc. can be compared with the threshold value preset, judge whether that there occurs supply blocks up.

In addition, identical with the variation 2 of embodiment 1, traffic presumption unit 217 also based on the position at detection vehicle positional information and energy recharge station, can estimate supply congestion information.In this situation, such as, the wheeled speed of the detection vehicle 151 being positioned at energy recharge station periphery can be obtained as a driving type information by traffic presumption unit 217, and judge whether this wheeled speed exceedes the threshold value preset.

In addition, in a series of process shown in Figure 10, supply congestion information is deduced to PHEV (HEV), EV, but also can deduce supply congestion information similarly to engine vehicle.In addition, when the vehicle receiving supply congestion information is PHEV (HEV), the EV generating above-mentioned charging plan, also energy recharge plan can be changed based on this supply congestion information, long as far as possible with the distance making to utilize gasoline to travel before arriving the charging station that do not get congestion.

(embodiment 2)

In embodiment 1, mainly the presumption driving operable type to sail speed is illustrated.Embodiments of the present invention 2 estimate the supply till accepting energy recharge based on this driving operable type speed of sailing and wait for, are below explained.In addition, the modular structure of the detection information system involved by present embodiment and the detection information system involved by embodiment 1 modular structure (Fig. 1) identical.Below, in description of the present embodiment, mark same label to the same or similar structure of textural element that illustrates in embodiment 1, and omit the description.In addition, the process of the vehicle side system 101 involved by present embodiment is identical with the process illustrated in embodiment 1, and therefore the description thereof will be omitted.

Figure 11 is the process flow diagram of the process of the central side system 201 represented involved by present embodiment.Herein, central side system 201 (traffic presumption unit 217) is based on the detection vehicle positional information comprised in the detection information received by central side acceptance division 231 and drive type information, namely drives the transmission traffic of type of vehicle number to estimate to the vehicle number of each driving type comprising (on each link) on each road.

Next, the presumption process of Figure 11 to the driving type of vehicle number of center side system 201 is utilized to be described in detail.In addition, the presumption process (Fig. 6 ~ Figure 10) illustrated in the presumption process below illustrated and embodiment 1 is carried out concurrently, or some phase earthing is carried out.

In step S41, central side acceptance division 231 receives the detection information from vehicle side system 101 directly or indirectly, and this detection information is supplied to detection DB server 213.The detection information that central side acceptance division 231 provides by detection DB server 213 stores according to time series order.In addition, the VICS information etc. received by communication interface part 211 is supplied to infrastructure DB server 216 by infrastructure information input part 215, and facilities information based on this VICS information etc. stores by infrastructure DB server 216.

In step S42, traffic presumption unit 217 carries out based on the detection information carrying out storing according to time series order in step S41 the presumption transmitting traffic.Herein, the driving type information that detection information comprises by traffic presumption unit 217 is provided to and is being stored on the position that the detection vehicle positional information that comprised by detection information in the map represented by the map datum in central side map data base 214 represents.Traffic presumption unit 217 by carrying out this process to the detection information from many detection vehicles 151, thus deduces the transmission traffic be included by the driving type of vehicle number corresponding with the driving type distributes on map.

Figure 12 and Figure 13 is the figure representing the driving type of vehicle number comprised in the transmission traffic that deduced by traffic presumption unit 217 in step S42.Such as, the driving type of vehicle number shown in Figure 12 shows engine vehicle on the road between place O and charging station SA1, the number of units of PHEV and EV is respectively 35,5,10.In addition, show between charging station SA1 and SA2 road with the driving type of vehicle number shown in Figure 12 on engine vehicle, PHEV and EV number of units be respectively 35,5,10.

In addition, the foot of form shown in Figure 12 and Figure 13 also shows the presumption result of the wheeled speed (being that the maximum driving operable type illustrated in the variation 1 of embodiment 1 sails speed Vmax) illustrated in embodiment 1 herein.

In addition, in present embodiment, traffic presumption unit 217, by calculating the summation driving type of vehicle number to each road, deduces total number of units of all vehicles be positioned on each road.In example shown in Figure 12, traffic presumption unit 217 drives 35 shown in type of vehicle number, the sum of 5,10 by calculating the road between place O and charging station SA1, and the total number of units deducing all vehicles be positioned on this road is 50.In addition, in example shown in Figure 12, similarly, traffic presumption unit 217 drives 35 shown in type of vehicle number, the sum of 5,10 by calculating the road between charging station SA1 and charging station SA2, and the total number of units deducing all vehicles be positioned on this road is 50.

In addition, in the present embodiment, traffic presumption unit 217 also deduces based on the charging plan (Fig. 2, Fig. 3) comprised in detection information and same charging station (being charging station SA2) will be utilized herein to accept the vehicle number charged.Right side one row of the form shown in Figure 12 show in multiple (in Figure 12 the being 20) EV on the road between place O and charging station SA2 that traffic presumption unit 217 deduces and charging station SA2 will be utilized to accept the presumption result (in Figure 12 being 5) of the vehicle number of charging power.

Get back to Figure 11, in step S43, traffic presumption unit 217 is revised driving type of vehicle number (transmission traffic) based on infrastructure information.Such as, as the present situation, because detection vehicle is fully not universal, the gross vehicle number of units of total number of units of the detection vehicle of each road therefore deduced in step S42 road each from reality is sometimes different.Therefore, in the situations such as this differs greatly, traffic presumption unit 217 is revised based on infrastructure information and is driven type of vehicle number.Such as, traffic presumption unit 217 is by the gross vehicle number of units of each road that deduces in the step S42 total number of units divided by the vehicle of each road shown in infrastructure information, obtain ratio, and this ratio is multiplied by the driving type of vehicle number deduced in step S42, revise and drive type of vehicle number.

In step S44, traffic presumption unit 217 stores (preservation) in traffic DB server 218 (storage part) by comprising through the transmission traffic of revised driving type of vehicle number.Then, the transmission traffic be stored in traffic DB server 218 is sent to the outsides such as each vehicle by central side sending part 232.

Next, in order to be described the effect of the vehicle side system 101 involved by the present embodiment that said structure is formed and central side system 201, Figure 14 pair of detection information system be associated with them (being denoted as below " associating detection information system ") is utilized to be described.

In association detection information system, from center side system, the sum of the detection vehicle be positioned at each road is sent to each vehicle.In the example shown in this Figure 14, be 50 by the detection vehicle comprised on the road that is positioned between place O (current location of the vehicle A of EV) and charging station SA1, detection vehicle on road between charging station SA1, SA2 is that the transmission traffic of 50 such information is sent to each vehicle.

Herein, even if vehicle A receives this transmission traffic, the driver of vehicle A also can only predict and 50 chassis may be made at most to accept charging at charging station SA1,50 chassis may be made at most to accept this degree of charging at charging station SA2.Therefore, driver cannot judge whether accept charging at charging station SA1, SA2, thus, when charging station SA1, SA2 generation charging is blocked up, when driver will accept charging at charging station SA1, SA2, the longer time must be waited for.

On the other hand, vehicle side system 101 involved according to the present embodiment and central side system 210, the driver of vehicle A can obtain driving type of vehicle number as shown in FIG. 12 and 13.If vehicle A receives the driving type of vehicle number shown in Figure 12, then the driver of vehicle A to dope charging stand-by period of charging station SA1, SA2 roughly the same.On the other hand, if vehicle A receives the driving type of vehicle number shown in Figure 13, then the charging stand-by period that the driver of vehicle A can dope charging station SA2 is longer than charging station SA1.Therefore, in this case, the driver of vehicle A can accept charging at charging station SA1.

Thus, vehicle side system 101 involved according to the present embodiment and central side system 201, the driver of each vehicle can obtain and drive type of vehicle number, thus as reference, can predict the charging stand-by period of charging station SA1, SA2 to a certain extent.Consequently, wait (supply wait) of charging for a long time can be avoided.

In addition, if as shown in row on the right side of the table of Figure 12 and Figure 13, based on the vehicle number that charging plan presumption will utilize same charging station to accept charging, and be included in transmission traffic, then can be improved the precision of prediction of charging stand-by period.

In addition, in said structure, when traffic presumption unit 217 can get from infrastructure information etc. each charging station carry out the current empty wagons number of the vehicle number (almost identical with the vehicle number shown in the supply congestion information illustrated the variation 2 of embodiment 1) of supply or each charging station, also this vehicle number (or this empty wagons number) can be included in transmission traffic.

In addition, above is mainly EV to accept the vehicle of transmission traffic, and energy recharge station and energy recharge plan are the situations of charging station and charging plan is that example is illustrated.But, be not limited thereto, such as, when the vehicle of acceptance transmission traffic is engine vehicle, if energy recharge station and energy recharge plan are set to refuelling station and bunkering schedule, then can obtain the effect identical with above-mentioned explanation.In addition, such as, when the vehicle of acceptance transmission traffic is PHEV (HEV), if energy recharge station is set to charging station or refuelling station, energy recharge plan is established and makes charging plan or bunkering schedule, then can obtain the effect identical with above-mentioned explanation.This is also identical in the following description.

< will accept the presumption > at the energy recharge station of energy recharge to each vehicle

As mentioned above, if be used as the charging plan of energy recharge plan, then can deduce the vehicle number (right side one of the table of Figure 12 and Figure 13 arranges) that an energy recharge station i.e. charging station will be utilized to accept supply.But, in practical application, central side system 201 sometimes cannot receiving package containing the detection information of energy recharge plan.Therefore, below the detection information system not using energy recharge plan just can improve the precision of prediction of supply stand-by period is described.

Herein, as prerequisite, in central side system 201, store the distribution (being also denoted as below " distribution of distance vehicle number ") of the ultimate range that can travel and the driving range extrapolated when driving type of vehicle number to utilize the current energy stored to travel relative to vehicle.In addition, such as, the charging driving range illustrated in the driving range of EV and Fig. 2 etc. is identical, such as, the driving range of PHEV (HEV) be roughly illustrate in Fig. 2 etc. charging driving range, and based on fuel stock distance and.

In addition, namely the ultimate range that the distance vehicle number distribution be stored in central side system 201 utilizes the unit of fixing driving range can travel to the vehicle extrapolated under being divided in current vehicle condition travel total distance, and vehicle presets to each unit there is probability.Such as, be 100km in the total distance of traveling, when fixing driving range is 10km, there is probability X1 in the driving range setting for 0 ~ 10km, there is probability X2 in the driving range setting for 10 ~ 20km, ... probability X10 (wherein, X1+X2+ is existed for the driving range setting of 90 ~ 100km ... + X10=100%).Herein, for convenience of description, there is probability X1 ~ X10 and be equal to each other, be i.e. X1=X2=...=X10=10%.But there is probability X1 ~ X10 and also can add weight according to statistics.

Driving type of vehicle number shown in Figure 12 and Figure 13 that traffic presumption unit 217 deduces based on itself and the distribution of distance vehicle number, deduce the driving type of vehicle number (being also denoted as below " distance drives type of vehicle number ") of each driving range.

Herein, traffic presumption unit 217 drives type of vehicle number by being estimated as distance to the value obtained after driving type of vehicle number to be multiplied by there is probability.

The example of Figure 12 to this presumption is utilized to be described.In this example, the number of units of the EV on the road showing between place O and charging station SA1 by driving type of vehicle number is 10.In this situation, traffic presumption unit 217 deduces and drives 10 middle driving ranges shown in type of vehicle number to be the driving type of vehicle number of 0 ~ 10km to be 1 (=drive type of vehicle number (10) × there is probability X1 (10%)).Equally, it be the driving type of vehicle number of 10 ~ 20km is 1 that traffic presumption unit 217 deduces driving range ..., driving range is the driving type of vehicle number of 90 ~ 100km is 1.

Next, traffic presumption unit 217 drives type of vehicle number based on the distance obtained by above-mentioned presumption, deduces the energy recharge station (charging station) that each vehicle will accept energy recharge (charging).In addition, the energy recharge station that also each vehicle will be accepted energy recharge is below denoted as " supply predetermined stations ".

Herein, traffic presumption unit 217 based on each vehicle driving path and with drive the corresponding energy recharge station of type (such as, when driving type to be EV type of drive for charging station) position (distance), come to drive type of vehicle number presumption supply predetermined stations according to distance.

The example of the position relationship shown in Figure 14 to this presumption is utilized to be described.In this example, traffic presumption unit 217 obtains the driving path sequentially through charging station SA1, SA2 from detection information etc., using the driving path of the vehicle A as EV, and, 30km is obtained respectively, using as the distance between place O and charging station SA1 and the distance between charging station SA1, SA2 from map datum etc.In this situation, because the distance between place O and charging station SA2 is 60km, therefore traffic presumption unit 217 deduce between place O and charging station SA1 road on 10 EV in driving range to accept charging at charging station SA1 at the EV of below 60km.

Herein, as shown in above-mentioned example, if it be the driving type of vehicle number of 10 ~ 20km is 1 that traffic presumption unit 217 estimates driving range, driving range is the driving type of vehicle number of 90 ~ 100km is 1, then estimate driving range and will accept energizing power at charging station SA1 at 6 chassis of below 60km.

The above-mentioned supply predetermined stations deduced is included in transmission traffic by traffic presumption unit 217, and sends (transmitting) to each vehicle.

According to above-mentioned vehicle side system 101 and central side system 201, the driver of each vehicle can obtain information, i.e. supply predetermined stations with equaling above-mentioned charging plan (energy recharge plan).Therefore, identical with this charging plan (energy recharge plan), the precision of prediction of supply stand-by period can be improved.

In addition, in the above description, supply predetermined stations is included in transmission traffic by traffic presumption unit 217, and the situation sending it to each vehicle is illustrated, but is not limited thereto.Such as, also can be included in apart from driving type of vehicle number in transmission traffic, send to each vehicle.In addition, if the vehicle (vehicle side system) receiving transmission traffic is identical with the central side system 201 of above-mentioned explanation, drives type of vehicle number presumption supply predetermined stations based on distance, then can obtain the effect identical with above-mentioned explanation.

In addition, such as, driving range is almost proportional with the fuel stock shown in fuel stock information.Therefore, traffic presumption unit 217 can based on the fuel stock information (energy inventory information) comprised in the detection information received by the driving type of vehicle number of presumption itself and central side acceptance division 231, deduce the driving type of vehicle number driving each driving range that type of vehicle number essence is identical with above-mentioned distance, and be included in transmission traffic, send to each vehicle.

In addition, herein, being illustrated the situation that energy inventory information is the fuel stock information relevant to the fuel stock such as gasoline, but being not limited thereto, also can be the charging inventory information relevant to charging storage.

In addition, the distance that traffic presumption unit 217 also can obtain based on based on fuel inventory information (energy inventory information) drives type of vehicle number, estimate supply predetermined stations identically with above-mentioned explanation, be included in transmission traffic, send to each vehicle.

In addition, even if drive type identical, also there is charging modes or the skimble-scamble area of charge port, country.Therefore, as shown in Fig. 2 etc., comprise the information of charge port at detection information, when traffic presumption unit 217 can obtain the information of charge port, also can estimate distance according to the information of this charge port and drive type of vehicle number or supply predetermined stations.Equally, when traffic presumption unit 217 can obtain the information of charging modes, also can estimate distance according to the information of this charging modes and drive type of vehicle number or supply predetermined stations.

In addition, when traffic presumption unit 217 can obtain the history at the energy recharge station accepting energy recharge in the past, also can drive type of vehicle number or supply predetermined stations with the position at this energy recharge station for benchmark estimates distance.In addition, traffic presumption unit 217 also can suppose that each vehicle accepted energy recharge with the probability of equalization at multiple energy recharge station, estimates distance and drives type of vehicle number or supply predetermined stations.

In addition, when traffic presumption unit 217 can obtain from infrastructure information etc. energy recharge station whether do business, also can estimate supply predetermined stations according to whether doing business.

In addition, for the vehicle of the band solar cell also using the electric power of solar cell to travel, driving range also changes according to weather.Therefore, the Weather information comprised in infrastructure information etc., preferably when driving type of vehicle number or supply predetermined stations to the vehicle presumption distance of band solar cell, is taken into account by traffic presumption unit 217.
