Wherein, in the situation that the speed of detection vehicle 151 surpasses statutory restrictions speed, travel, from the viewpoint of abidance by rule, wheeled speed Veng should be estimated as to the speed v of detection vehicle 151.Therefore, the related traffic of present embodiment is inferred portion 217 wheeled speed Veng is estimated as to one less in the represented speed v of detection vehicle velocity information and maximum speed limit.(maximum speed limit v) just means this meaning to Veng=Min shown in Fig. 7.In addition,, for maximum speed limit herein, use in the maximum speed limit of storing one to one with each road in advance in map datum and infer the corresponding maximum speed limit of object road.Afterwards, a series of processing as shown in Figure 7 finishes.
In step S24, traffic is inferred the power consumption of portion 217 based on getting in step S21 and is suppressed driving mode information, judges that it is open or close that power consumption suppresses driving mode.In the situation that power consumption suppresses driving mode unlatching, advance to step S25, in the situation that power consumption inhibition driving mode is closed, advance to step S26.
Herein, judge power consumption suppress in situation that driving mode opens by step S24, to suppress energy consumption, have precedence over travel speed and travel, therefore, although think that in fact road is more empty, the possibility of not travelling with high as far as possible speed is larger.Therefore, think that on this road, can surmount power consumption suppresses the detection vehicle 151 that driving mode is opened, 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 S25, traffic infer portion 217 by the wheeled speed (being also denoted as below " Vphev ") of inferring the PHEV type of drive in object road be estimated as the value above and below maximum speed limit of the speed v shown in detection vehicle velocity information be f1 (maximum speed limit, v).Equally, in step S25, traffic infer portion 217 by the wheeled speed (being also denoted as below " Vev ") of inferring the EV type of drive in object road be estimated as the value above and below maximum speed limit of the speed v shown in detection vehicle velocity information be f2 (maximum speed limit, v).
Herein, f1 (maximum speed limit, v) and f2 (maximum speed limit, is v) function of maximum speed limit and speed v, if get the above and value below maximum speed limit of speed v, can be arbitrary function.For example, also can be f1 (maximum speed limit, v)=maximum speed limit, and f2 (maximum speed limit, v)=maximum speed limit, or can be also 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).Below explanation in, 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) describes.Afterwards, a series of processing as shown in Figure 7 finishes.
In addition, by step S24, judging power consumption suppresses, in situation that driving mode closes, to think that the driver of detection vehicle 151 just travels with high as far as possible speed.That is to say, think on this road, the travel speed of vehicle only can be increased to the same uniform velocity left and right that power consumption suppresses the detection vehicle 151 that driving mode closes.
Therefore, in step S26, traffic infer portion 217 by the wheeled velocities Vp hev that infers the PHEV type of drive in object road (position) be estimated as Min (maximum speed limit, v), by the wheeled speed Vev of EV type of drive be estimated as Min (maximum speed limit, v).Afterwards, a series of processing as shown in Figure 7 finishes.
Above, to inferred portion 217 by traffic, infer and drive the processing of type wheeled speed to be illustrated.In addition, in the above description, at step S21, by traffic, infer portion 217 and obtain a detection information.Yet, in step S21, in traffic, infer portion 217 obtained a plurality of detection vehicle velocity information for a kind of driving type (drive type information) in the situation that, also can use the statistical value (for example mean value or maximal value) of the speed v shown in a plurality of detection vehicle velocity informations to replace above-mentioned speed v.
Get back to Fig. 6, after the processing of step S12 finishes, in step S13, traffic is inferred 217 pairs, portion and is driven type wheeled speed (transmission traffic) to revise.For example, suppose in the situation that adopt and can get the structure that drives type wheeled speed from infrastructure information, will get from this infrastructure information and drive type wheeled speed, compare with the driving type wheeled speed of inferring out among step S12.In both difference in the situation that defined threshold is above, traffic is inferred portion 217 can reduce the fiduciary level that these drive type wheeled speed, or only make these drive in type wheeled speed one effectively, or using both mean value as revised driving type wheeled speed.Or, in the situation that can only get the speed of the detection vehicle 151 of PHEV type of drive (HEV type of drive) or EV type of drive, wheeled speed that also can be using the wheeled type speed getting from infrastructure information as engine driving mode.
In step S14, traffic is inferred portion 217 and is stored (preservation) to traffic DB server 218 by comprising through the transmission traffic of revised driving type wheeled speed.Then, central side sending part 232 is sent to the outsides such as each vehicle by the transmission traffic being stored in traffic DB server 218.
According to the related vehicle side system 101 of present embodiment as above and central side system 201, infer out driving type wheeled speed, and this driving type wheeled speed is sent to each vehicle.Herein, it has been generally acknowledged that the wheeled speed of the vehicle (for example engine vehicle) without power consumption inhibition driving mode is greater than the wheeled speed of the vehicle (for example PHEV) with power consumption inhibition driving mode, and closer to actual wheeled speed.According to present embodiment, each vehicle can obtain does not have the wheeled speed that power consumption suppresses the vehicle (for example engine vehicle) of driving mode, using as driving type wheeled speed, therefore can improve the reliability of the wheeled speed of inferring out, and then improve the reliability of detection information system.Herein, in the wheeled speed without the vehicle of power consumption inhibition driving mode (being engine vehicle) herein, be low speed once in a while, and there is the wheeled speed of vehicle (for example PHEV) that power consumption suppresses driving mode in situation at a high speed, think and there is the wheeled speed of vehicle (for example PHEV) that power consumption suppresses driving mode close to actual wheeled speed.According to present embodiment, each vehicle can obtain has the wheeled speed that power consumption suppresses the vehicle (for example PHEV) of driving mode, using as driving type wheeled speed, therefore can improve the reliability of the wheeled speed of inferring out, and then improve the reliability of detection information system.

(variation 3 of embodiment 1)

Figure 10 means in above-mentioned steps S12, and the related traffic of this variation is inferred the figure that infers processing of the transmission traffic that portion 217 carries out.In a series of processing shown in this Figure 10, traffic is inferred the driving type wheeled speed of a plurality of driving types that portion 217 infers out based on itself, infers out the congestion information relevant to the energy recharge at energy recharge station (supply congestion information).Below, utilizing Figure 10 to infer to process to this is elaborated.
As shown in figure 10, traffic is inferred portion 217 and in step S21～S27, is carried out processing same as described above.Then, after step S27, in step S31, traffic is inferred portion 217 and is judged whether to set supply congestion information is inferred.Setting supply congestion information is inferred in the situation that, advance to step S32, not set supply congestion information is inferred in the situation that, a series of processing shown in Figure 10 finishes.
In step S32, traffic infer portion 217 according to the wheeled speed Veng of engine driving mode up to the present getting, the wheeled speed Vev of the wheeled velocities Vp hev of PHEV type of drive and EV type of drive, judging is Vphev < g1 (Veng), or Vev < g2 (Veng).G1 (Veng), g2 (Veng) are the functions of Veng, and herein, with g1 (Veng)=Veng/5, the situation of g2 (Veng)=Veng/5 describes.
The in the situation that of being judged as Veng < g1 (Veng) in step S32, advance to step S33, traffic is inferred portion 217 and is generated supply congestion informations, and this supply congestion information is illustrated in charging station on the corresponding road of driving type wheeled speed used herein (Vphev) or refuelling station and charging has occurred blocks up or refuel and block up.Afterwards, a series of processing as shown in figure 10 finishes.On the other hand, the in the situation that of being judged as Vphev >=g1 (Veng) in step S32, advance to step S34, traffic is inferred portion 217 and is generated supply congestion informations, and this supply congestion information is illustrated in charging station on the corresponding road of driving type wheeled speed used herein (Vphev) or refuelling station and charging does not occur blocks up or refuel and block up.Afterwards, a series of processing as shown in figure 10 finishes.

(embodiment 2)
In embodiment 1, mainly to driving inferring of type wheeled speed to be illustrated.Embodiments of the present invention 2 are inferred based on this driving type wheeled speed the supply of accepting till energy recharge and are waited for, are below explained.In addition, the modular structure of the related detection information system of the present embodiment detection information system related with embodiment 1 modular structure (Fig. 1) identical.Below, in description of the present embodiment, to embodiment 1 in the same or similar structure of textural element of explanation mark same label, and description thereof is omitted.In addition, the processing of the vehicle side system 101 that present embodiment is related is identical with the processing of explanation in embodiment 1, and therefore the description thereof will be omitted.
Figure 11 means the process flow diagram of the processing of the central side system 201 that present embodiment is related.Herein, the detection vehicle positional information of central side system 201 (traffic is inferred portion 217) based on comprising in the received detection information of central side acceptance division 231 and drive type information, drives the vehicle number of type to drive type of vehicle number to infer in interior transmission traffic to each that comprises (on each link) on each road.
Next, utilize Figure 11 that inferring of the driving type of vehicle number of center side system 201 processed and be elaborated.In addition, below the processing (Fig. 6～Figure 10) of inferring of inferring explanation in processing and embodiment 1 of explanation is carried out concurrently, or carry out in some phase earthing.
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 offered and surveys DB server 213.The detection information that surveying DB server 213 provides central side acceptance division 231 is stored according to time series order.In addition, infrastructure information input part 215 offers infrastructure DB server 216 by received VICS information of communication interface part 211 etc., and infrastructure DB server 216 is stored this VICS information etc. as infrastructure information.
In step S42, traffic is inferred the detection information of portion 217 based on storing according to time series order in step S41 and is transmitted inferring of traffic.Herein, traffic is inferred driving type information that portion 217 comprises detection information and is provided on the position that the detection vehicle positional information that comprised by detection information in the represented map of map datum in being stored in central side map data base 214 represents.Traffic is inferred portion 217 and is carried out this processing by the detection information to from many detection vehicles 151, thereby infers out the transmission traffic that the driving type with on map is distributed driving type of vehicle number corresponding and be included.
Figure 12 and Figure 13 mean in step S42 the figure that is inferred the driving type of vehicle number comprising in the transmission traffic that portion 217 infers out by traffic.For example, the number of units that the driving type of vehicle number shown in Figure 12 shows engine vehicle, PHEV and EV on the road between place O and charging station SA1 is respectively 35,5,10.In addition, the number of units that shows engine vehicle, PHEV and EV on the road between charging station SA1 and SA2 with the driving type of vehicle number shown in Figure 12 is respectively 35,5,10.
In addition, the foot of form shown in Figure 12 and Figure 13 also show in embodiment 1 explanation wheeled speed (being herein the maximum driving type wheeled speed Vmax of explanation in the variation 1 of embodiment 1) infer result.
In addition,, in present embodiment, traffic is inferred portion 217 by each road being calculated to the summation that drives type of vehicle number, infers out total number of units of all vehicles that are positioned on each road.In example shown in Figure 12, traffic is inferred portion 217 and is calculated and driven the sum of 35,5,10 shown in type of vehicle number by the road between place O and charging station SA1, and total number of units of inferring out all vehicles that are positioned on this road is 50.In addition, in example shown in Figure 12, similarly, traffic is inferred portion 217 and is calculated and driven the sum of 35,5,10 shown in type of vehicle number by the road between charging station SA1 and charging station SA2, and total number of units of inferring out all vehicles that are positioned on this road is 50.
In addition, in the present embodiment, traffic infer portion 217 also the charging plan based on comprising in detection information (Fig. 2, Fig. 3) infer and will utilize same charging station (herein for charging station SA2) to accept the vehicle number of charging.Right side one row of the form shown in Figure 12 show traffic infer in a plurality of (in Figure 12 the being 20) EV on the road between place O and charging station SA2 that portion 217 infers out, to utilize charging station SA2 accept charging power vehicle number infer result (in Figure 12 being 5).
Get back to Figure 11, in step S43, traffic is inferred portion 217 and based on infrastructure information, driving type of vehicle number (transmission traffic) is revised.For example, as the present situation, because detection vehicle is fully not universal, total number of units of the detection vehicle of each road of therefore inferring out in step S42 is sometimes different from the gross vehicle number of units of actual each road.Therefore in the situations such as this differs greatly, traffic is inferred portion 217 and is revised and drive type of vehicle number based on infrastructure information.For example, traffic infer portion 217 by the gross vehicle number of units of each road of inferring out in step S42 the 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 of inferring out in step S42, revise and drive type of vehicle number.
In step S44, traffic is inferred portion 217 and is stored (preservation) to traffic DB server 218 (storage part) by comprising through the transmission traffic of revised driving type of vehicle number.Then, central side sending part 232 is sent to the outsides such as each vehicle by the transmission traffic being stored in traffic DB server 218.
Next, for the effect of the related vehicle side system 101 of the present embodiment consisting of said structure and central side system 201 is described, utilize Figure 14 pair of detection information system being associated with them (being denoted as below " associated detection information system ") to describe.
In associated detection information system, from center side system, the sum that is positioned at the detection vehicle each road is sent to each vehicle.In the example shown in this Figure 14, by comprising detection vehicle on the road being positioned between place O (current location of the vehicle A of EV) and charging station SA1, it is 50, the detection vehicle on the 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 at charging station SA1 and may make at most 50 vehicles accept charging, at charging station SA2, may make at most 50 vehicles accept this degree of charging.Therefore, driver cannot judge whether at charging station SA1, SA2, accept charging, thereby, in the situation that charging station SA1, SA2 generation charging is blocked up, when driver will be when charging station SA1, SA2 accept charging, the necessary longer time of wait.
On the other hand, according to the related vehicle side system 101 of 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, it is roughly the same that the driver of vehicle A can dope charging stand-by period of charging station SA1, SA2.On the other hand, if vehicle A receives the driving type of vehicle number shown in Figure 13, the charging stand-by period that 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, according to the related vehicle side system 101 of present embodiment and central side system 201, the driver of each vehicle can obtain and drive type of vehicle number, thereby as reference, can predict to a certain extent the charging stand-by period of charging station SA1, SA2.Consequently, can avoid charging for a long time to wait for (supply wait).
In addition, if as shown in table right side one row of Figure 12 and Figure 13, based on charging plan, infer and will utilize same charging station to accept the vehicle number of charging, and be included in transmission traffic, can improve the precision of prediction of charging stand-by period.
In addition, in said structure, in traffic, infer that portion 217 can just get from infrastructure information etc. in the situation that each charging station carries out the vehicle number (almost identical with the vehicle number shown in the supply congestion information of explanation the variation 2 of embodiment 1) of supply or the current empty wagons number of 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 that the situation of charging station and charging plan is that example is illustrated.Yet, be not limited to this, for example, in the situation that accept the vehicle of transmission traffic, be engine vehicle, if energy recharge station and energy recharge plan are made as to refuelling station and bunkering schedule, can obtain the effect identical with above-mentioned explanation.In addition, for example, in the situation that accept the vehicle of transmission traffic, be PHEV (HEV), if energy recharge station is made as to charging station or refuelling station, energy recharge plan is established and made charging plan or bunkering schedule, can obtain the effect identical with above-mentioned explanation.This is also identical in the following description.
< to each vehicle, to accept energy recharge energy recharge station infer >
As mentioned above, if be used as the charging plan of energy recharge plan, can infer out and will utilize an energy recharge station is the vehicle number (right side one row of the table of Figure 12 and Figure 13) that a charging station is accepted supply.Yet in practical application, central side system 201 cannot receive the detection information that comprises energy recharge plan sometimes.Therefore,, the detection information system of 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 that the ultimate range that can travel of extrapolating in the situation that drives type of vehicle number to utilize the current energy of having stored to travel with respect to vehicle is driving range (being also denoted as below " distributing apart from vehicle number ").In addition, for example, in the driving range of EV and Fig. 2 etc., the charging driving range of explanation is identical, for example, the driving range of PHEV (HEV) be roughly explanation in Fig. 2 etc. charging driving range, with distance based on fuel stock and.
In addition, be stored in distance vehicle number in central side system 201 ultimate range that the vehicle that utilizes the unit of fixing driving range to be divided in to extrapolate under current vehicle-state can the travel total distance of travelling that distributes, and each unit preset to the probability that exists of vehicle.For example, travelling, total distance is 100km, fixing driving range is in the situation of 10km, for the driving range of 0～10km, set and have probability X1, for the driving range of 10～20km, set and have probability X2, ... for the driving range of 90～100km, set and have probability X10 (wherein, X1+X2+ ... + X10=100%).For convenience of description, exist probability X1～X10 to be equal to each other, i.e. X1=X2=herein ...=X10=10%.But exist probability X1～X10 also can add weight according to statistics.
Traffic is inferred Figure 12 and the driving type of vehicle number shown in Figure 13 that portion 217 infers out based on itself and is distributed apart from vehicle number, infers out the driving type of vehicle number (being also denoted as below " distance drives type of vehicle number ") of each driving range.
Herein, traffic is inferred portion 217 and will be driven type of vehicle number to driving type of vehicle number be multiplied by exist the value obtaining after probability to be estimated as distance.
