Description

  The present invention relates to a vehicle-to-vehicle power transmission / reception system that transmits and receives power between vehicles and a vehicle-mounted power transmission / reception control device used in this system.

  Conventionally, in order to efficiently use the power energy of a vehicle, when the power of the host vehicle is insufficient, the power is received from the outside of the vehicle, and when the power of the host vehicle has a margin, the power is supplied to the outside of the vehicle. An electric power supply system for transmitting power to the network has been proposed. For example, according to Patent Document 1, when a regenerative energy or the like is collected and there is a margin in the remaining capacity of the battery, surplus power is transmitted from the in-vehicle power supply device to the outside of the vehicle. Thereby, the recovered regenerative energy can be effectively utilized.

Japanese Patent Laying-Open No. 2005-210843

  When surplus power is transmitted to the outside of the vehicle, it is necessary to determine the amount of transmitted power so that the host vehicle does not run out of power. In particular, when power is transmitted to a power receiving vehicle after movement, it is necessary to determine surplus power at the time of arrival at the place where power is transmitted, taking into account the amount of power consumed during movement.

  However, the in-vehicle power supply device described in Patent Document 1 simply has a configuration in which the recovered regenerative energy is used as surplus power, and the surplus power is determined without considering the amount of power consumed by movement or the like. Yes. For this reason, there is a possibility that the vehicle on the power transmission side will run out of power.

  The present invention has been made based on this situation, and the purpose thereof is an inter-vehicle power transmission / reception system capable of suppressing a situation where a power transmission vehicle cannot transmit the amount of power required for the power receiving vehicle, And it is providing the vehicle-mounted power transmission / reception control apparatus which comprises the system.

In order to achieve the object, the invention according to claim 1 is an inter-vehicle power transmission / reception system in which a power receiving vehicle and a power transmitting vehicle perform power transmission / reception at a running power receiving point, and a plurality of candidates for the power transmission vehicle.

  According to a fifth aspect of the present invention, the center-side device includes power transmission / reception point determination means for determining a point where the power transmission vehicle and the candidate vehicle can arrive at substantially the same time as a power transmission / reception point.

  In this way, after the candidate vehicle is determined to be the power transmission vehicle, the time for one of the power transmission vehicle and the power receiving vehicle to wait for the other at the power transmission / reception point is shortened.

It is a figure explaining the process of FIG. 8 in association with the movement of a vehicle. It is a flowchart which shows the process performed after power transmission / reception.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a vehicle side system 100 to which the present invention is applied.

  The vehicle-side system 100 includes a power storage device 110, a power unit 120, an in-vehicle terminal 130, and a transmission / reception device 140. A mobile terminal 150 can also be added. Of these, the configuration excluding the power storage device 110 corresponds to the in-vehicle power transmission / reception control device in the claims.

  The power storage device 110 includes a battery 111 such as a lithium ion secondary battery or a nickel hydride secondary battery, and a battery sensor 112 that detects the voltage and charge / discharge current of the battery 111. The battery 111 supplies power to a motor (not shown) that is a driving force source of the vehicle.

  The power unit 120 includes a power amount management unit 121, a cruising range management unit 122, and a power transmission / reception unit 123. The power amount management unit 121 sequentially determines the remaining power amount of the battery 111 based on a signal from the battery sensor 112 of the power storage device 110. This remaining power amount is determined by, for example, calculating the current SOC value by a known method and multiplying the current SOC value by the rated capacity of the battery 111. Further, the remaining power amount may be determined by multiplying the difference between the current SOC value and the minimum SOC by the rated capacity. The cruising range management unit 122 sequentially calculates the cruising range of the host vehicle based on the remaining power amount sequentially determined by the power amount management unit 121. For example, the cruising range is calculated by dividing the remaining power amount by the estimated cruising range per unit power. There are various methods for calculating the estimated cruising distance per unit power. For example, the average cruising distance per unit power in the past traveling history of a predetermined period can be set as the estimated cruising distance per unit power. Further, the minimum cruising distance per unit power in the past travel history of a predetermined period may be the estimated cruising distance per unit power. These are cases where the host vehicle is an electric vehicle, but in a hybrid vehicle that also uses an engine, the cruising distance may be determined by adding the distance that can be traveled by fuel.

  The power amount management unit 121 is also equivalent to the current surplus amount determining means in the claims, and in addition to sequentially determining the remaining power amount, the surplus power amount of the battery 111 and the necessary power reception amount are also determined. Determine sequentially. The surplus power amount is a power amount that is surplus (margin) in vehicle travel at the present time. This surplus electric energy can be determined by various methods. For example, on the condition that the user determines the surplus power determination SOC and exceeds the surplus power determination SOC, the power amount corresponding to a predetermined percentage of the SOC can be set as the surplus power amount. Further, all the excess power determination SOC may be used as the surplus power amount. The surplus power determination SOC may have an initial value set in advance.

  The amount of power required for power reception can also be determined by various methods. For example, first, a destination is set. Then, a difference distance between the distance on the route from the current position to the destination and the cruising distance is calculated. The product of the difference distance and the amount of power required per unit distance is set as the required power amount for receiving power. In addition, as an electric energy required per unit distance, the average value in the past driving performance is used, for example. Moreover, you may determine the amount of electric power required for receiving power without using the destination. For example, when the user determines the insufficient power determination SOC and falls below the insufficient power determination SOC, the amount of power corresponding to a predetermined percentage of the SOC may be set as the required power amount. Further, the insufficient power determination SOC may be set in advance instead of the user setting. Further, the user may directly input the required power amount for receiving power.

  The power transmission / reception unit 123 has a mechanical configuration for transmitting power from the battery 111 to another vehicle, receiving power from the other vehicle, and storing the power in the battery 111. The battery 111 can also store regenerative energy generated by the motor.

  As the in-vehicle terminal 130, for example, a navigation device can be used. The in-vehicle terminal 130 includes a storage unit 131 that stores a vehicle ID that is identification information of a vehicle on which the vehicle-side system 100 is mounted, and a set price per unit power of sold power (transmitted power). As the vehicle ID, for example, there is a registration number. Further, in addition to the information that can individually identify the vehicles, the vehicle ID may include type information that can identify the type of the vehicle (such as vehicle type, vehicle weight, and driving power source). The storage unit 131 can rewrite the stored information, and the set price is set by the user. The own vehicle position determination unit 132 sequentially determines the current position of the own vehicle using, for example, a GPS receiver. The transmission / reception control unit 133 transmits the information in the in-vehicle terminal 130 and the information in the power unit 120 from the transmission / reception device 140 to the center side system 200 (FIG. 2), and is transmitted from the center side system 200. Get the received information.

  The transmission / reception device 140 is a device that transmits and receives signals wirelessly. Information transmitted from the transmission / reception device 140 to the center-side system 200 includes a vehicle ID, a set price, a host vehicle position (vehicle position information), a cruising distance, a remaining power amount of the battery 111, a surplus power amount, and a power required for receiving power. There is a quantity. Information that changes sequentially, such as vehicle position information, is transmitted at a fixed period. Moreover, the determination method of the surplus electric power amount for every vehicle and the determination method of electric power reception required amount may be transmitted. Further, the transmission / reception device 140 also transmits various information based on user input. Examples of this information include power reception request information when power reception is necessary, and power transmission acceptance information in a power transmission vehicle. The power reception request information includes the necessity of power reception, and the above-described vehicle ID, vehicle position information, cruising range, and required power reception amount.

  The mobile terminal 150 is a device that executes part or all of the functions of the in-vehicle terminal 130 instead of the in-vehicle terminal 130. The mobile terminal 150 includes a storage unit 151 and a position determination unit 152. The storage unit 151 can rewrite the stored information, and the user can store the vehicle ID and the set price of the sales power in the storage unit 151. The position determination unit 152 sequentially determines the current position of the mobile terminal 150. When the portable terminal 150 is mounted on a vehicle, the current position determined by the portable terminal 150 is the current position of the vehicle. The mobile terminal 150 is connected to the in-vehicle terminal 130 wirelessly or by wire, and can transmit the stored information in the storage unit 151 and the current position determined by the position determining unit 152 to the in-vehicle terminal 130. Further, it is also possible to acquire information from the in-vehicle terminal 150 and use the portable terminal 150 as a substitute for the transmission / reception device 140.

  Next, the configuration of the center side system 200 of FIG. 2 will be described. The center-side system 200 corresponds to the center-side device in the claims, and includes a main arithmetic device 210, various databases 220 to 224, a transmission / reception device 230, and a communication control device 240.

  The transmission / reception device 230 receives various information transmitted from the transmission / reception device 140 of the vehicle-side system 100. The received information is acquired by the communication control device 240 and sent to the main arithmetic unit 210. The transmission / reception device 230 is supplied with various information determined by the main arithmetic unit 210 via the communication control device 240, and transmits the information to the transmission / reception device 140 of the vehicle-side system 100.

  The communication control device 240 includes a push delivery unit 241 and a WEB browsing service processing unit 242. The push delivery unit 241 push-distributes the predetermined type of information determined by the main arithmetic unit 210 to the vehicle-side system 100 mounted on the vehicle set as the push delivery destination. In response to a request from the vehicle-side system 100, the WEB browsing service processing unit 242 performs various types of information (set price, surplus power, vehicle position) about surrounding vehicles existing around the vehicle on which the vehicle-side system 100 is mounted. ) To the vehicle-side system 100 that requested the information.

  The main arithmetic unit 210 includes a vehicle information processing unit 211, a target narrowing processing unit 212, a search processing unit 213, a power consumption prediction unit 214, and a billing processing unit 215.

  The vehicle information processing unit 211 performs a process of storing vehicle information transmitted from the vehicle-side system 100 mounted on a plurality of vehicles in the vehicle information DB 221. The vehicle information includes a vehicle ID, vehicle position information, and a cruising range. Each vehicle-side system 100 also transmits a remaining power amount, a surplus power amount, and a required power reception amount. The vehicle information processing unit 210 performs processing for storing the information related to the electric energy in the electric power consumption record DB, and calculates the electric energy consumption record associated with the movement of each vehicle based on the vehicle position information described above. To do. The power consumption consumption record is specifically the power consumption for each road section (for example, between adjacent nodes). This power consumption consumption record is stored in the power consumption consumption DB 220.

  The personal information management DB 222 stores a large number of personal information. The personal information here is personal information necessary for charging when surplus power is sold, and includes personal name, address, and card information for settlement. Further, the set price of the sales power may be stored in the personal information management DB 222 as personal information instead of vehicle information. Information is registered in the personal information management DB 222 in advance. As a device for registration, the above-described portable terminal 150 and in-vehicle terminal 130 are used. Further, registration may be performed from another device, for example, a home computer.

  The billing information management DB 223 stores the correspondence between the power receiving vehicle and the power transmitting vehicle when the power receiving vehicle and the power transmitting vehicle are determined one-to-one. Further, when the power transmission / reception between the power receiving vehicle and the power transmission vehicle is completed and the transmission / reception power amount is determined, the transmission / reception power amount is stored in association with the power reception vehicle and the power transmission vehicle. The map information DB 224 stores road map data used for route search.

  The description returns to the main arithmetic unit 210. The target narrowing-down processing unit 212 narrows down the power transmission vehicles when there is a power reception request from a vehicle that needs to receive power (power receiving vehicle). Specifically, first, as a primary narrowing down, the vehicles that are within the cruising distance of the power receiving vehicle from the current position of the power receiving vehicle and that have a power transmission function are narrowed down. A vehicle having a power transmission function is specifically a vehicle on which the vehicle-side system 100 is mounted. This is because the vehicle including the vehicle-side system 100 includes the power transmission / reception unit 123 as a power transmission function. In addition, since the vehicle including the vehicle-side system 100 sequentially transmits the current position to the center-side system 200, the center-side system 200 can grasp the current position.

  Further, secondary narrowing is performed after this primary narrowing. In the secondary narrowing down, of the vehicles narrowed down by the primary narrowing (hereinafter referred to as primary candidate vehicles), the surplus power amount at the point where power is transmitted / received (power transmission / reception point) exceeds the power reception required power amount of the power receiving vehicle Refine to. The power transmission / reception point is determined by the search processing unit 213 described below. In addition, the predicted value in the power consumption prediction unit 214 is used to calculate the surplus power amount at the power transmission / reception point.

  The search processing unit 213 calculates a route and a required time from the current position of the vehicle to the destination using the map DB 224 and a known route search algorithm. Vehicles for which route search is performed by the search processing unit 213 are primary candidate vehicles and power receiving vehicles that are narrowed down by the primary narrowing down of the target narrowing-down processing unit 212. A power transmission / reception point candidate as a destination is also set for these vehicles. The power transmission / reception point candidate is a position where the power receiving vehicle and the primary candidate vehicle are candidates for power transmission / reception. When both the power receiving vehicle and the primary candidate vehicle travel toward the power transmission / reception point candidate, positions where they can arrive at substantially the same time are set as power transmission / reception point candidates. Of course, the power transmission / reception point candidates are limited to the cruising distance of the power receiving vehicle and the primary candidate vehicle. As a simple example, a position where the distance from each other's vehicle is substantially equal can be set as a power transmission / reception point candidate. Further, reachable ranges that can be reached after a predetermined time from the current position are calculated. When the predetermined time is gradually increased, the reachable ranges of the vehicles overlap at a certain time. A place within this overlapping range is set as a power transmission / reception point candidate. The reachable range may be a circle centered on the current position, but may be limited to a predetermined distance from the route when the route is set (or estimated). Here, the overlapping area of the reachable range is set to a certain size, and a plurality of power transmission / reception point candidates are set in the area. That is, a plurality of power transmission / reception point candidates are set for one primary candidate vehicle. Then, a route search is performed for all set power transmission / reception point candidates.

  Then, with respect to the plurality of primary candidate vehicles, the amount of surplus power in the plurality of power transmission / reception point candidates is predicted by the power consumption prediction unit 214. As a result of the prediction, the vehicle that is predicted that the surplus power amount at the power transmission / reception point candidate exceeds the power reception required power amount is the secondary candidate vehicle. The secondary candidate vehicle and the power transmission / reception point candidate of the secondary candidate vehicle are transmitted to the vehicle side system 100 by the communication control device 240 and the transmission / reception device 230 and displayed on a display unit (not shown) of the vehicle side system 100. Based on the user operation, one secondary candidate vehicle is selected as the power transmission vehicle, and one power transmission / reception point is selected. The display mode in the display unit displays the power transmission / reception point candidates in different colors according to the distance from the host vehicle (power receiving vehicle). For example, power transmission / reception point candidates that are close to the host vehicle are displayed in blue, and the closer to the host vehicle, the closer to red the color is displayed. In this way, the user of the power receiving vehicle can easily select the power transmitting vehicle. The display unit also displays a set price for each secondary candidate vehicle.

  In addition, when the power transmission / reception point is finally determined by the user, the search processing unit 213 also searches each route of the power receiving vehicle and the power transmission vehicle up to the power transmission / reception point.

  The power consumption prediction unit 214 also functions as a surplus power prediction unit, and predicts power consumption until reaching the power transmission / reception point candidate for the primary candidate vehicle. For this prediction, the power consumption for each road section stored in the power consumption record DB 220 is used. The power consumption record DB 220 stores the past power consumption of a large number of vehicles for each road section. For example, the average value of the past power consumption is calculated for each road section, and the average value is calculated. Is estimated as the power consumption of the road section. The power consumption prediction unit 214 further subtracts the total amount of power consumption predicted for each road section to the destination from the remaining power amount of the primary candidate vehicle at the current time, thereby calculating the remaining power amount at the power transmission / reception point candidate. Predict. Furthermore, the surplus power at the power transmission / reception point candidate is predicted from the predicted remaining power amount based on the method for determining the surplus power amount determined for each primary candidate vehicle. On the other hand, for the power receiving vehicle, the power reception required power amount at the power transmission / reception point candidate is predicted by the same method.

  In the secondary narrowing in the target narrowing processing unit 212, the primary candidate vehicles are further narrowed down by using the surplus power amount and the power reception required power amount predicted in this way.

  The power consumption prediction unit 214 also predicts the power consumption amount to the power transmission / reception point from the vehicle position information sequentially transmitted from the power transmission vehicle and the power reception vehicle to the power transmission / reception point. To do.

  In the above-described target narrowing processing unit 212, while the power transmission vehicle and the power receiving vehicle are heading to the power transmission / reception point, the remaining power amount of the power transmission vehicle and the power receiving vehicle and the power consumption amount predicted by the power consumption prediction unit 214 are sequentially calculated. Whether the power transmission vehicle and the power receiving vehicle can arrive at the power transmission / reception point, how much power is required to be received by the power receiving vehicle at the power transmission / reception point, and how much surplus power of the power receiving vehicle at the power transmission / reception point is sequentially predicted. And, for some reason, the surplus power amount of the power transmission vehicle is less than the power reception required power amount of the power receiving vehicle at the power transmission / reception point due to traffic jams, bad weather, sudden transmission of the power transmission vehicle, transmission to another vehicle, etc. If it can be determined, narrow down alternative power transmission vehicles. The process of narrowing down alternative power transmission vehicles is a process of determining a new power transmission vehicle at that time, and the same process as when a power transmission vehicle is first determined.

  The correspondence between the power receiving vehicle and the power transmitting vehicle is finally determined when the user of the power receiving vehicle selects one power transmitting vehicle and the user of the selected power transmitting vehicle accepts power transmission. The charging processing unit 215 registers the association between the user of the power transmission vehicle and the user of the power receiving vehicle in the charging information management DB when the above correspondence is confirmed. Then, when the transmission / reception of power is completed, a charge determined from the amount of transmitted power (= the amount of received power) and the set price set by the power transmitting vehicle is charged to the user of the power receiving vehicle.

  Next, the process of the vehicle-to-vehicle power transmission / reception system including the vehicle-side system 100 and the center-side system 200 will be described with reference to a flowchart.

  FIG. 3 is a flowchart for registering personal information and vehicle information. This process is started by a registration start instruction operation by the vehicle user, and is performed in advance before the next FIG.

  First, step S31 is a process performed by the vehicle-side system 100, and the name, address, card information, set price of sales power, etc. stored in the storage unit 131 of the in-vehicle device 130 or the storage unit 151 of the mobile terminal 150, etc. Is transmitted to the center-side system 200.

  Step S32 is a process of the center side system 200, and the personal information transmitted from the vehicle side system 100 is registered in the personal information management DB 222.

  Step S33 is a process performed by the vehicle-side system 100, and transmits vehicle information such as a vehicle ID to the center-side system 200. Step S34 is a process of the center side system 200, and the vehicle information transmitted from the vehicle side system 100 is registered in the vehicle information management DB 221.

  FIG. 4 is a flowchart showing a process for determining a power transmission vehicle. This flowchart is started when the user of the power receiving vehicle inputs an operation to instruct the start of the power transmission / reception process to the in-vehicle device 130. Alternatively, the power amount management unit 121 may determine whether or not the destination can be reached, and may automatically start when it is determined that the destination cannot be reached.

  First, in step S401 (corresponding to the power reception required power amount notification means in the claims), the vehicle side system 100 notifies the center side system 200 of the cruising distance and the power reception required power amount at the present time. Hereinafter, the vehicle that has made this notification is referred to as a power receiving vehicle. Note that the vehicle-side system 100 mounted on each of a plurality of vehicles other than the power receiving vehicle sequentially transmits the current position and surplus power amount to the center-side system 200 as candidate vehicles. This transmission process corresponds to the candidate vehicle information notification means in the claims.

  Steps S402 to 405 are performed by the center system 200. In step S402, the above-described primary narrowing is performed. That is, of the vehicles provided with the vehicle-side system 100, the vehicles that have been notified of the cruising distance are narrowed down to the vehicles that exist within the cruising distance from the position of the vehicle. The narrowed-down vehicle is the primary candidate vehicle described above.

  In step S403, the above-described secondary narrowing is performed. That is, of the primary candidate vehicles narrowed down in step S402, a vehicle whose surplus power at the power transmission / reception point candidate exceeds the power reception required power amount of the power receiving vehicle is searched. Vehicles narrowed down as a result of this search are secondary candidate vehicles. In addition, in this process, you may acquire further the power transmission intention of the user of a vehicle, and may further limit to the user with power transmission intention.

  In step S403, in order to calculate the surplus power amount at the power transmission / reception point candidate, the power transmission / reception point candidate is set for each primary candidate vehicle by the method described in FIG. Then, the surplus power of the primary candidate vehicle at each power transmission / reception point candidate is calculated from the surplus power at the present time of these primary candidate vehicles and the power consumption up to the power transmission / reception point candidate.

  In step S404, for the secondary candidate vehicles narrowed down in step S403, one or a plurality of power transmission / reception point candidates with the power receiving vehicle are determined, and the route and required time to the power transmission / reception point candidate are determined. Calculation is performed for each of the power receiving vehicle and the secondary candidate vehicle.

  In step S405, the calculation result of step S404 is transmitted to the power receiving vehicle. In addition, when the number of vehicles narrowed down by step S403 is larger than a predetermined number, you may limit the number of vehicles which transmit a calculation result based on the distance and required time to a power transmission / reception point candidate.

  Step S406 is processing of the vehicle-side system 100 and selects a power transmission user (power transmission vehicle). In this selection, based on the narrowing-down result received from the center-side system 200, the power transmission / reception point candidate with each secondary candidate vehicle, the distance to the power transmission / reception point candidate, the required time, and the current position of the secondary candidate vehicle indicate. Further, according to the distance, the power transmission / reception point with the secondary candidate vehicle, the current position of the secondary candidate vehicle, or both) are displayed in different colors. Thereby, it can be judged from the difference in color which secondary candidate vehicle can be transmitted and received in a short distance. After this display, one secondary candidate vehicle is selected as a power transmission vehicle by a user operation. In addition, when there are a plurality of power transmission / reception point candidates for the selected secondary candidate vehicle, one candidate value store is selected as the power transmission / reception point.

  In step S407, the center side system 200 is notified of the selection result. In step S408, the center side system 200 notifies the power transmission vehicle selected by the user of the power receiving vehicle of the selection. This notification includes a power transmission / reception point with the power receiving vehicle, a route to the power transmission / reception point, and a required time to the power transmission / reception point.

  Step S409 is a process performed by the vehicle-side system 100 of the power transmission vehicle, and selects whether or not the response is possible as an answer to whether or not the response is possible. This selection is performed based on an input operation by the user of the power transmission vehicle.

  In step S410, the center side system 200 is notified of the selection result of step S409. Step S411 is executed when response is selected in step S409. On the other hand, when the response is selected, although not shown, the power transmission vehicle is notified of the response, and the process returns to step S406.

  In step S411, association processing between a power transmission user and a power reception user is performed. In this association process, the vehicle ID is acquired from the vehicle that has notified that power transmission is possible, the vehicle ID is also acquired from the power receiving vehicle, and the vehicle ID and the storage contents of the vehicle information management DB 221 and the personal information management DB 222 are obtained. Based on.

  In step S412, the association is registered in the billing information management DB 223. In step S413, the power receiving vehicle notifies the power receiving vehicle that the power transmission vehicle has replied that power transmission is possible, and also notifies the power transmitting vehicle that the power receiving vehicle has been notified. In step S414, the vehicle-side system 100 of the power transmission vehicle and the vehicle-side system 100 of the power reception vehicle each start route guidance to the power transmission / reception point. When the power transmission / reception point is reached, the route guidance is terminated (step S415).

  FIG. 5 is a diagram illustrating steps S411, S414, and S415. As shown in FIG. 5, the host vehicle (power receiving vehicle) is associated with the other vehicle A (power transmitting vehicle) (S411), and then route guidance to the power transmission / reception point is started (S414). And other vehicle A start moving to the power transmission / reception point. When both the host vehicle and the other vehicle A arrive at the power transmission / reception point (S415), power transmission / reception is performed between the vehicles.

  If both the own vehicle and the other vehicle A can travel with the planned power consumption, it is possible to transmit the required power amount from the power transmission vehicle to the power reception vehicle at the power transmission / reception point. However, it is conceivable that power may be consumed unexpectedly due to traffic jams and the like.

  Therefore, the center-side system 200 moves to the power transmission / reception point while the power receiving vehicle and the power transmission vehicle are moving toward the power transmission / reception point, that is, after performing step S414 in FIG. Then, it is sequentially monitored whether the power receiving vehicle and the power transmitting vehicle are traveling at the planned power consumption. While the power receiving vehicle and the power transmitting vehicle are moving toward the power transmission / reception point, the center side system 200 sequentially transmits information necessary for managing the power consumption amount.

  FIG. 6 shows information for managing power consumption sequentially while the host vehicle (power receiving vehicle) and the other vehicle A (power transmitting vehicle) are moving toward the power transmission / reception point G. It is a figure explaining transmitting to 200. FIG.

  As shown in the figure, the other vehicle A sequentially transmits the surplus power amount to the center side system 200. In addition to the surplus power amount, the remaining power amount, the position of the vehicle, and the vehicle ID are also transmitted. On the other hand, the host vehicle sequentially transmits the power reception required power amount to the center system 200. In addition to the power reception required power amount, the remaining power amount, the vehicle position, and the vehicle ID are also transmitted.

  The center-side system 200 determines the actual power consumption for each road section based on the remaining electric power sequentially transmitted from the power receiving vehicle, the power transmitting vehicle, and the position of the vehicle, and stores the actual power consumption in the power consumption performance DB 220. . The actual power consumption is stored separately for electric vehicles and hybrid vehicles. Further, the vehicle type may be stored. Further, not only the power receiving vehicle and the power transmitting vehicle, but a vehicle equipped with the vehicle side system 100 sequentially transmits the remaining power amount and the vehicle position to the center side system 200.

  The center-side system 200 uses the power consumption amount consumed while the power receiving vehicle moves from the current position to the power transmission / reception point based on the power consumption performance stored in the power consumption performance DB 220 for the same type of vehicle as the power receiving vehicle. Predict. FIG. 7 is a diagram for explaining the predicted electric energy. As shown in this figure, based on the power consumption record stored in the power consumption record DB 220, when the powered vehicle travels on each road section such as the P1-P2 section, the P2-P3 section,. Predict power consumption. Then, it is sequentially predicted whether the power receiving vehicle can reach the power transmission / reception point from the predicted value of the power consumption amount from the current position to the power transmission / reception point and the remaining power amount of the power receiving vehicle at the present time.

  The center-side system 200 also predicts the power consumption from the current position to the power transmission / reception point for the power transmission vehicle in the same manner as for the power reception vehicle. Then, the surplus power amount of the power transmission vehicle at the power transmission / reception point is predicted by subtracting the predicted power consumption amount from the surplus power amount of the power transmission vehicle at the current time. In addition, it is good also as predicting the surplus electric energy of the power transmission vehicle in a power transmission / reception point by subtracting the estimated electric power consumption from the remaining electric energy.

  When it is determined that the power receiving vehicle and the power transmitting vehicle cannot perform the power transmission / reception as scheduled at the power transmission / reception point as a result of the prediction for the power receiving vehicle or the power transmission vehicle, the power transmission / reception plan is reviewed.

  This process will be described with reference to FIGS. The process of FIG. 8 is performed when route guidance is performed to a power transmission / reception point.

  In step S801, the power receiving vehicle and the power transmitting vehicle continue to move to the power transmission / reception point. In step S <b> 802, the power transmitting vehicle and the power receiving vehicle transmit the power reception required power amount and the surplus power amount to the center system 200, respectively.

  In step S803, the center-side system 200 compares the surplus power amount of the power transmission vehicle with the power reception required power amount of the power receiving vehicle. It is also determined whether the power receiving vehicle and the power transmitting vehicle can travel to the power transmission / reception point.

  In step S804, based on the determination result in step S803, it is determined whether or not power transmission / reception as planned can be performed at the power transmission / reception point. If it is determined that power transmission / reception can be performed as scheduled (S804: YES), the process returns to step S801. On the other hand, if it is determined that the scheduled power transmission / reception is not possible, the power receiving vehicle and the power transmitting vehicle are notified of the power transmission / reception impossible information indicating that the scheduled power transmission / reception cannot be performed by push distribution.

  Then, another power transmission vehicle that transmits power to the power receiving vehicle is determined by performing step S402 and subsequent steps in FIG.

  FIG. 9 is a diagram for explaining the processing of FIG. 8 in association with the movement of the vehicle. Initially, the host vehicle (power receiving vehicle) was scheduled to perform power transmission / reception at the power transmission / reception point G1 using the other vehicle A as a power transmission vehicle, and moved toward the power transmission / reception point G1. However, it was determined that the surplus power amount of the other vehicle A was insufficient during the movement. Therefore, the other vehicle B is determined as a new power transmission vehicle, and a new power transmission / reception point G2 is determined. Therefore, the host vehicle changes the destination to the power transmission / reception point G2, and the other vehicle B also starts traveling toward the power transmission / reception point G2. And after arriving at the own vehicle, the other vehicle B, and the power transmission / reception point G2, electric power transmission / reception is performed among those vehicles.

  FIG. 10 is a flowchart illustrating processing performed after power transmission / reception. First, in step S101, the amount of transmitted power transmitted by the power transmission vehicle is calculated. In step S102, the transmitted power amount is notified from the power transmission vehicle to the center system 200. This notification includes the vehicle ID of the vehicle that has notified this information.

  In step S103, from the charging information management DB 223, the user of the power receiving vehicle performing charging and the user of the power transmitting vehicle performing deposit are read from the ID of the power transmitting vehicle. In step S104, the set price of the user of the power transmission vehicle is read from the personal information management DB 222.

  In step S105, charging processing unit 215 performs charging processing. Specifically, the charge amount is calculated by multiplying the transmission power amount acquired in step S102 by the set price read in step S104. A billing process is performed to charge the billing amount to the user of the power receiving vehicle. This billing process is, for example, a withdrawal process from a credit card account. In addition, for the user of the power transmission vehicle, a deposit process for depositing the charge amount is performed. In step S106, the charging history and the payment history are registered in the charging information management DB 223.

  As described above, according to the embodiment described above, the surplus power amount at the power transmission / reception point of the candidate vehicle is determined in consideration of the power consumption due to movement, and the candidate vehicle having the surplus power amount larger than the power reception required power amount is determined as the power transmission vehicle. Determine as. Therefore, a situation in which the power transmission vehicle cannot transmit the power required for power reception to the power reception vehicle at the power transmission / reception point is suppressed.

  Further, according to the present embodiment, while the power transmission vehicle is moving to the power transmission / reception point, it is sequentially determined whether the predicted value of the surplus power amount of the power transmission vehicle exceeds the power reception required power amount of the power reception vehicle. ing. Therefore, when the power transmission vehicle consumes a large amount of battery power contrary to prediction while moving, another power transmission vehicle can be promptly determined.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, The following embodiment is also contained in the technical scope of this invention, and also the summary other than the following is also included. Various modifications can be made without departing from the scope.

  For example, in the above-described embodiment, the center-side system 200 determines the power transmission / reception point, but the method for determining the power transmission / reception point is not limited to the above-described embodiment. For example, the user of the power receiving vehicle may specify the power transmission / reception point.

  Further, in the above-described embodiment, when it is determined that the first power transmission vehicle cannot transmit the power required for receiving power, the alternative power transmission vehicles are narrowed down. Instead of this, additional power transmission vehicles may be narrowed down.

  The process of narrowing down additional power transmission vehicles is performed under the condition that the power receiving vehicle can still supply the amount of power (insufficient power) that is still insufficient even if the power receiving vehicle receives power from the first power transmission vehicle. This is the process to be performed. Also in this case, when there are a plurality of candidate vehicles, the user of the power receiving vehicle is selected, and when the user of the power transmitting vehicle also accepts power transmission, it is finally determined as an additional power transmitting vehicle. This determination process corresponds to the second power transmission vehicle determination means in the claims. In this narrowing down, a plurality of second candidate vehicles that are candidates for additional power transmission vehicles (corresponding to the second power transmission vehicle) are determined, and the current surplus power amount is acquired from these vehicles (current surplus amount). Acquisition means). And the power consumption of the battery by the 2nd candidate vehicle moving to a run receiving point is predicted (2nd power consumption prediction means). The second candidate vehicle is narrowed down under the condition that the distance from the power transmission / reception point is within a predetermined distance. Next, the surplus power amount of the second candidate vehicle at the running power reception point is predicted from the power consumption amount of the battery due to the second candidate vehicle moving to the power transmission / reception point and the current surplus power amount of the second candidate vehicle. (Second surplus amount predicting means). Then, the insufficient power amount is compared with the surplus power amount at the power transmission / reception point of the second candidate vehicle, and the second candidate vehicle having the surplus power amount larger than the insufficient power amount is set as a candidate for the second power transmission vehicle. After the candidate is determined, the same processing as that for the first power transmission vehicle is performed to determine one second power transmission vehicle.
