Although not shown, the route information may be transmitted from the processing device 230 to the driver's mobile terminal (such as a smart phone), and the travel route may be displayed on the driver's mobile terminal.

FIG. 4 is a diagram illustrating an example of the power supply system 350 arranged along the power supply lane Lp. Referring to FIG. 4 , a power feeding system 350 used for contactless power feeding while traveling includes a plurality of contactless power feeding facilities 320 and a controller 351 for the contactless power feeding facilities 320 . The control device 351 includes a communication device 330 and a processing device 340 . Although six contactless power supply facilities 320 are illustrated in FIG. 4, the number of contactless power supply facilities 320 is not limited to this.

Each contactless power supply equipment 320 includes a power transmission coil and receives power supply from an AC power supply (both not shown). By forming an electromagnetic field around the power transmission coil, wireless power supply equipment 320 can wirelessly transmit power to power reception coil 160 of vehicle 100 coupled to the power transmission coil through the electromagnetic field.

Communication device 330 is configured to be capable of wide-area communication with communication device 210 of vehicle control server 200 through a communication network. Communication device 330 is also configured to be able to communicate with communication module 190 of vehicle 100 by short-range wireless communication.

The processing device 340 includes a processor 341 such as a CPU and a memory 342 . Memory 342 includes ROM and RAM. The CPU 341 expands the program stored in the ROM into the RAM and executes it. Programs stored in the ROM describe various processes to be executed by the processing device 340 .

Vehicle 100 transmits vehicle information of vehicle 100 to vehicle control server 200 through communication module 190 when non-contact charging is performed while the vehicle is running. The vehicle information includes, for example, the account information of the owner of vehicle 100, the vehicle ID, the requested power (or requested power amount) indicating the requested value of the received power (or power amount) from power supply system 350, and the current position of vehicle 100. information, and information of the receiving coil 160 (size, height from the ground, etc.), and the like.

Upon receiving the vehicle information of vehicle 100 from vehicle 100 , vehicle control server 200 stores the vehicle information in vehicle information DB 222 and transmits the vehicle information of vehicle 100 to power supply system 350 through communication device 210 .

After transmitting the vehicle information to the vehicle control server 200, the vehicle 100 transmits the vehicle ID from the communication module 190 through short-range wireless communication. When the power supply system 350 receives the vehicle ID transmitted from the vehicle 100 by the communication device 330 and detects that the vehicle 100 approaches the power supply system 350, the power supply system 350 enters an active state in which electric power is supplied to the contactless power supply equipment 320. . In this state, when power receiving coil 160 of vehicle 100 reaches above non-contact power supply equipment 320, power is transmitted from non-contact power supply equipment 320 to power receiving coil 160 of vehicle 100 in a non-contact manner through an electromagnetic field.

When the power supply system 350 cannot receive the vehicle ID transmitted from the vehicle 100 by short-range wireless communication at the communication device 330, the power supply to the non-contact power supply equipment 320 is stopped, and the power supply system 350 supplies power to the vehicle 100. ends.

Snow 900 exists between the power transmission coil of contactless power supply equipment 320 and power reception coil 160 of vehicle 100 on power supply lane Lp shown in FIG. In this way, when snow 900 is interposed between both coils, the snow 900 can interfere with electromagnetic field coupling between the two coils, thereby preventing energy transmission from the power transmitting coil of wireless power supply equipment 320 to power receiving coil 160. obtain. As a result, the amount of power supplied from contactless power supply equipment 320 to running vehicle 100 may be less than the estimated amount of power supplied under conditions where no snow cover is assumed.

Therefore, in the vehicle control system 1, the vehicle control server 200 uses the weather information of the area including the power supply lane Lp, which is acquired from the weather information server 400, to determine whether snow 900 exists on the power supply lane Lp. judge. When it is determined that snow 900 exists on power supply lane Lp, vehicle 100 is guided to a specific route from the current location of vehicle 100 to the destination including power supply lane Lp. Snow 900 interposed between power supply lane Lp and power receiving coil 160 of vehicle 100 can be melted by heat generated when power is supplied from power supply lane Lp to vehicle 100 . As a result, it is possible to suppress a decrease in the power supply efficiency of the contactless power supply equipment 320 due to accumulated snow. Note that when it is determined that snow 900 exists on power supply lane Lp, there is a possibility of snowfall on power supply lane Lp. It includes a case where it exists and a case where snowfall is predicted on the power supply lane Lp based on the weather information.

FIG. 5 is a diagram showing two travel routes R1 and R2 from the current location of the vehicle 100 to the destination. Referring to FIG. 5, travel route R1 includes power supply points P0, P1, P2, P3, P4, and P5. Traveling route R2 includes feeding points P0, P6, P7, and P8. The travel route R2 is an optimum route that satisfies the criterion that the travel distance from the current location to the destination is the shortest.

The power supply point P0 is the current location. A contact power supply facility 310 and a contactless power supply facility 320 are provided at the power supply point P0. At power feeding point P0, vehicle 100 is capable of contact charging by contact power feeding facility 310 and non-contact charging by non-contact power feeding facility 320 while parked.

Each of the feeding points P1, P2, P5, P6 is provided with a feeding lane Lp comprising a feeding system 350. FIG. Vehicle 100 can receive contactless power supply from power supply system 350 while traveling on power supply lane Lp corresponding to each of power supply points P1, P2, P5, and P6.

Each of the power supply points P3, P4, P7, and P8 is a facility or the like (for example, a shopping mall, a convenience store, or the like) along the travel route R1. A contact power feeding facility 310 is provided at the power feeding points P3, P7, and P8. At each of power feeding points P3, P7, and P8, vehicle 100 is capable of contact charging by contact power feeding equipment 310. FIG. A contactless power supply facility 320 is provided at the power supply point P4. At power supply point P4, vehicle 100 can be charged wirelessly by wireless power supply facility 320 while the vehicle is parked.

FIG. 6 is a diagram showing driving route R2 displayed on display 182 in FIG. 3 when snowfall information is not included in the weather information for the area including power supply lane Lp in FIG. Vehicle control server 200 determines from the weather information that there is no snow on power supply lane Lp of FIG. .

FIG. 7 is a diagram showing how the travel route R1 (specific route) is displayed on the display 182 of FIG. 3 when the weather information of the region including the power supply lane Lp of FIG. 5 includes snowfall information. be. In FIG. 7, snowfall information is included in the weather information for the area including the power supply points P1 and P2. Vehicle control server 200 melts snow present at power supply points P1 and P2 with heat generated during contactless power supply from contactless power supply equipment 320 to vehicle 100, thereby preventing a decrease in power supply efficiency of contactless power supply equipment 320. In order to suppress this, a guidance instruction is output to vehicle 100 for displaying travel route R1 on display 182 . Specifically, the vehicle control server 200 guides the vehicle 100 to the travel route R1 when the excess time obtained by subtracting the required time of the travel route R2 from the travel time of the travel route R1 is shorter than a reference time (for example, one hour). . By shortening the excess time required for suppressing a decrease in the power supply efficiency of the contactless power supply equipment 320 from the reference time, it is possible to prevent the comfort of the driver of the vehicle 100 from deteriorating due to the request for excessive cooperation.

FIG. 8 is a flow chart showing an example of a procedure of processing until vehicle information of vehicle 100 is stored in vehicle information DB 222 of vehicle control server 200 . A series of processes shown in the flowchart are repeatedly executed in the vehicle 100 and the vehicle control server 200 at predetermined intervals or each time a predetermined condition is satisfied. The same applies to the flow charts shown in FIGS. 9-12.

Referring to FIG. 8, in vehicle 100, ECU 170 acquires position information of the current location of vehicle 100 from GPS receiver 181 (step S1). ECU 170 transmits vehicle information of vehicle 100 including the acquired position information of the current location to vehicle control server 200 (step S2).

In the vehicle control server 200, the processing device 230 determines whether vehicle information has been received (S101). When vehicle information is received (YES in step S101), processing device 230 stores the received vehicle information in the vehicle information DB (step S102). If vehicle information has not been received (NO in step S101), processing device 230 shifts the process to RETURN without executing subsequent processes.

FIG. 9 is a flow chart showing an example of a procedure of processing until the vehicle control server 200 guides the vehicle 100 to a specific route including the power supply lane Lp with the possibility of snowfall. Referring to FIG. 9, in vehicle control server 200, processing device 230 acquires weather information from weather information server 400 (step S111). The processing device 230 determines whether or not there is an area where snowfall is predicted among the areas included in the acquired weather information (step S112). If there is no region where snowfall is predicted (NO in step S112), processing device 230 shifts the process to RETURN without executing the subsequent series of processes.

If there is an area where snowfall is predicted (YES in step S112), processing device 230 determines whether power supply lane Lp is included in the area where snowfall is predicted (step S113). If power supply lane Lp is not included in the area where snowfall is predicted (NO in step S113), processing device 230 shifts the process to RETURN without executing the subsequent series of processes.

If power supply lane Lp is included in the area where snowfall is predicted (YES in step S113), processing device 230 can reach the destination through power supply lane Lp in the area where snowfall is predicted. It is determined whether or not the specific vehicle exists (step S114). If there is no specific vehicle that can reach the destination through power supply lane Lp in the area where snowfall is expected (NO in step S114), processing device 230 returns without executing the subsequent series of processes. and process.

If there is a specific vehicle (vehicle 100) that can reach the destination through power supply lane Lp in the area where snowfall is predicted (YES in step S114), processing device 230 selects a vehicle in the area where snowfall is predicted. It is determined whether or not the excess time obtained by subtracting the required time of the optimum route from the current location to the destination from the required time of the specific route from the current location to the destination passing through the power supply lane Lp is shorter than the reference time. If the excess time is equal to or longer than the reference time (NO in step S115), processing device 230 shifts the process to RETURN without executing the subsequent series of processes.

If the excess time is shorter than the reference time (YES in step S115), processing device 230 transmits a guidance instruction to the specific route to the specific vehicle (step S116). The guidance instruction includes information on the specific route and information on the power supply lane Lp where snow may exist. Processing device 230 transmits the ID information of the specific vehicle to power supply system 350 arranged in power supply lane Lp included in the specific route (step S117).

In vehicle 100, ECU 170 determines whether or not a guidance instruction including a specific route has been received from vehicle control server 200 (step S11). If no guidance instruction has been received from vehicle control server 200 (NO in step S11), ECU 170 shifts the process to return without executing the subsequent series of processes.

When the guidance instruction is received from vehicle control server 200 (YES in step S11), ECU 170 displays the specific route included in the received guidance instruction on display 182 (step S12). The ECU 170 sets a guidance flag to 1 (TRUE) indicating that the guidance instruction has been received from the vehicle control server 200 (step S13). The driver of vehicle 100 can know the specific route by visually recognizing display 182 . The initial value of the guidance flag is 0 (FALSE).

In power feeding system 350, processing device 340 determines whether or not vehicle ID information has been received from vehicle control server 200 (step S211). When vehicle ID information is received from vehicle control server 200 (YES in step S211), ECU 170 records the received vehicle ID information in the guided vehicle list (step S212). If vehicle ID information has not been received from vehicle control server 200 (NO in step S211), ECU 170 shifts the process to RETURN without executing subsequent processes.

FIG. 10 is a flowchart showing an example of a procedure of processing until vehicle control server 200 provides an incentive to vehicle 100 that has traveled a specific route that includes power supply lane Lp with the possibility of snowfall. Referring to FIG. 10, in vehicle 100, ECU 170 determines whether or not the guidance flag is 1 (S21). If the guidance flag is 0 (NO in step S21), ECU 170 shifts the process to RETURN without executing the subsequent series of processes. If the guidance flag is 1 (YES in step S21), ECU 170 tracks changes in the current location over time to acquire the trajectory of the vehicle (step S22). The ECU 170 uses the acquired trajectory of the vehicle 100 to determine whether or not the vehicle 100 is traveling along the specific route (step S23).

If vehicle 100 is traveling on the specific route (YES in step S23), ECU 170 obtains the ID of vehicle 100 in order to obtain an incentive for contributing to the reduction in power supply efficiency of power supply lane Lp. The vehicle control server 200 is requested to make an incentive request including the incentive request (step S24). Incentives include, for example, discounts on usage fees for power supply equipment managed by vehicle control server 200, or various points. After transmitting the incentive request, the ECU 170 sets the guidance flag to 0 (step S25).

If vehicle 100 is not traveling on the specific route (NO in step S23), ECU 170 determines whether or not the specific route can be taken from the current location (step S26). If the specific route can be taken from the current location (YES in step S26), ECU 170 returns the process to step S22. If the specific route cannot be taken from the current location (NO in step S26), ECU 170 sets the guidance flag to 0 (step S25).

The power feeding system 350 performs a power feeding process (step S<b>220 ) and transmits a power feeding completion notification to the vehicle control server 200 . Vehicle control server 200 provides an incentive to vehicle 100 in response to the incentive request from vehicle 100 and the power supply completion notification from power supply system 350 in the incentive provision process (step S120). Vehicle control server 200 functions as an incentive granting device.

To motivate the driver of a vehicle 100 to travel the specific route even when the time required for the specific route is longer than the time required for the optimum route by giving an incentive according to traveling the specific route. can be done.

FIG. 11 is a flow chart showing an example of specific processing procedures for each of the incentive provision processing and the power supply processing in FIG. 10 . Referring to FIG. 11, in vehicle 100, ECU 170 transmits vehicle ID information to power supply system 350 using short-range communication (step S31).

In power feeding system 350, processing device 340 determines whether or not vehicle ID information (first identification information) has been received from the vehicle (step S221). If the vehicle ID information has not been received from the vehicle (NO in step S221), processing device 340 shifts the process to RETURN without executing the subsequent series of processes. If vehicle ID information has been received from the vehicle (YES in step S221), processing device 340 determines whether or not the guided vehicle list includes a vehicle ID (second identification information) that matches the received vehicle ID ( step S222).

If the vehicle ID that matches the received vehicle ID is not included in the guided vehicle list (NO in step S222), processing device 340 sets the power supply amount to the vehicle to the reference power supply amount (step S224). If the guided vehicle list includes a vehicle ID that matches the received vehicle ID (YES in step S222), processing device 340 determines the amount of power to be supplied to the vehicle without increasing the power supply charge (power supply cost). The power supply amount is set to be larger than the power supply amount (step S223). After setting the amount of power to be supplied to the vehicle, the processing device 340 starts preparing to supply power to the vehicle (step S225).

Processing device 340 determines whether or not the vehicle has entered power supply lane Lp (step S226). If the vehicle is not in the power supply lane (NO in step S226), processing device 340 determines again whether the vehicle has entered power supply lane Lp (step S226). If the vehicle has entered power supply lane Lp (YES in step S226), processing device 340 starts supplying power to the vehicle (step S227).

After power is supplied to the vehicle that has entered the power supply lane, processing device 340 determines whether the vehicle has left the power supply lane (step S228). If the vehicle has not left the power supply lane (NO in step S228), processing device 340 determines again whether the vehicle has left the power supply lane (step S228). If the vehicle has left the power supply lane (YES in step S228), processing device 340 transmits to vehicle control server 200 a power supply completion notification including the ID of the vehicle to which power has been supplied this time (step S229). After transmitting the power supply completion notification, the processing device 340 deletes the ID of the vehicle to which power has been supplied this time from the guided vehicle list (step S230).

As the specific route is traveled according to the guidance instruction, the amount of power supplied from the power supply lane Lp is increased without increasing the power supply charge, so that the time required for the specific route is longer than the time required for the optimum route. Even if it is long, the driver of the vehicle 100 can be motivated to follow the guidance instructions to the specific route.

In vehicle control server 200, processing device 230 determines whether or not an incentive request has been received from vehicle 100 (step S121). If an incentive request has not been received from vehicle 100 (NO in S121), processing device 230 shifts the process to RETURN without executing the subsequent series of processes. When an incentive request has been received from vehicle 100 (YES in step S121), processing device 230 determines whether or not a power supply completion notification has been received from power supply system 350 (step S122).

If a power supply completion notification has not been received from power supply system 350 (NO in step S122), processing device 230 proceeds to return without executing the subsequent series of processes. When the power supply completion notification is received from power supply system 350 (YES in step S122), processing device 230 determines whether or not the vehicle ID included in the power supply completion notification matches the vehicle ID included in the incentive request (step S124). If the vehicle ID included in the power supply completion notification matches the vehicle ID included in the incentive request (YES in step S123), processing device 230 executes processing for providing incentives to the account associated with the vehicle ID (step S124). ). If the vehicle ID included in the power supply completion notification does not match the vehicle ID included in the incentive request (NO in step S123), processing device 230 proceeds to return without executing subsequent processing.

In the embodiment, the configuration for guiding the vehicle to a specific route (vehicle guidance device) is described in the case where the vehicle control server 200 different from the vehicle 100 has the configuration. may have Further, in the embodiment, both a configuration for guiding a vehicle to a specific route and a configuration for providing an incentive to a vehicle that has traveled the guided specific route (incentive giving device) are combined into one device (vehicle control server 200). has been described, the vehicle guidance device and the incentive provision device may be different from each other.
