As a method of charging the in-vehicle battery of such an electric vehicle or a hybrid vehicle, a method of charging with the regenerative power of a motor generated during deceleration or downhill road driving while the vehicle is running, or a method of charging based on an engine is driven. In addition to the method of charging using a generator, there is a method of charging at home or at a dedicated charging facility.

However, the place where the charging facility is located is limited, and it is not always near the vehicle when the remaining amount of the in-vehicle battery decreases. Therefore, it is conceivable to have the electric power transferred from the same electric vehicle or hybrid vehicle instead of the fixed charging facility. As such a system for transferring energy between vehicles, for example, Japanese Patent Application Laid-Open No. 2013-333403 states that when there is a vehicle in which the remaining amount of the in-vehicle battery is reduced, the vehicle travels near a vehicle having a sufficient remaining amount of the in-vehicle battery. A system has been proposed in which a route is set so as to allow the vehicle to be charged, and the vehicle battery is charged while driving by wireless power transmission from a vehicle having a sufficient remaining amount of the vehicle battery.

It basically has a certain navigation device 5. Further, the server device 3 and the navigation device 5 are configured to be able to send and receive electronic data to and from each other via the communication network 6. Instead of the navigation device 5, for example, a mobile phone, a smartphone, a tablet terminal, or a personal computer may be used.

Further, the vehicle 4 is a vehicle equipped with at least a motor as a drive source and an in-vehicle battery 7 as a means for supplying electric power to the motor as the drive source, and the in-vehicle battery 7 can be charged in the charging facility. Make it a possible vehicle. Applicable vehicles include electric vehicles (hereinafter referred to as EV vehicles) that use only a motor as a drive source, and hybrid vehicles that use both a motor and an engine as a drive source, especially plug-in hybrid vehicles (hereinafter, PHV vehicles). There is).

Further, in particular, in the present embodiment, the vehicle 4 has a function of transferring the energy (electric power) stored in the vehicle-mounted battery 7 to another vehicle 4 or receiving the energy (electric power) from the other vehicle 4. As for the transfer of electric power between vehicles, for example, it is possible to transfer the electric power cables by connecting them to each other's power supply ports, or it is possible to transfer the electric power by non-contact (wireless) power transmission. Examples of non-contact power transmission include an "electromagnetic induction method" using electromagnetic induction and a "magnetic field resonance method" using the phase adjustment phenomenon of the magnetic field generated when the coil resonates. By providing the vehicle 4 with a power transmission coil for power transmission and a power reception coil for power reception, it is possible to transfer electric power between the vehicles by the above-mentioned "electromagnetic induction method" or "magnetic field resonance method". In this embodiment, an example in which power is transferred by a contact type method in which power cables are connected to each other's power supply ports will be described.

The server device 3 is a device that supports the transfer of electric power between the plurality of vehicles. Specifically, when there is a vehicle 4 in which the energy (remaining power amount) stored in the vehicle-mounted battery 7 is insufficient for the energy required for traveling to the destination, the remaining amount of the vehicle-mounted battery 7 is used. Search for a vehicle 4 that can afford to transfer power. In addition, it also searches for recommended locations for transferring power (hereinafter referred to as recommended transfer locations). Then, after the vehicle 4 to which the power is to be transferred and the vehicle 4 to be transferred are determined, information on the recommended transfer location (for example, the name of the recommended transfer location, the position coordinates of the recommended transfer location, and the recommendation) are given to each vehicle 4. Deliver the route to the transfer location). In addition, information that identifies the other party's vehicle 4 (for example, vehicle type) is also distributed.

Further, the server device 3 is communicably connected to the parking lot management server 8 that manages parking lots all over the country. The parking lot management server 8 monitors the availability of parking spaces provided in the parking lot to be managed. Here, in the case of transferring electric power between the plurality of vehicles, the parking lot is basically searched as the recommended transfer location by the server device 3. Whether or not there is an empty space for parking the vehicle in the parking lot is an important index when deciding the recommended transfer location.

The information is transmitted together with the route search request (however, in the case of re-search, the information about the destination does not necessarily have to be transmitted). Then, the server device 3 that has received the route search request performs a route search using the map information possessed by the server device 3 and specifies a recommended route from the departure point to the destination. After that, the specified recommended route is transmitted to the requesting navigation device 5. Then, the navigation device 5 provides the user with information on the received recommended route, sets the recommended route as the guidance route, and performs movement guidance according to the guidance route. As a result, even if the map information possessed by the navigation device 5 at the time of route search is an old version of the map information or the navigation device 5 does not have the map information itself, the latest version of the map possessed by the server device 3 is available. It is possible to provide a recommended route to an appropriate destination based on the information.

Subsequently, the power transfer support processing program executed by the server device 3 and the navigation device 5 having the above configuration will be described with reference to FIGS. 5 and 6. 5 and 6 are flowcharts of the power transfer support processing program according to the present embodiment. Here, the electric power transfer support processing program is a program that is executed at predetermined time intervals (for example, at intervals of 200 ms) to support the transfer of electric power between a plurality of vehicles. Further, the programs shown in the flowcharts of FIGS. 5 and 6 below are stored in the RAM 52 and ROM 53 of the navigation ECU 33, the RAM 22 and ROM 23 of the server device 3, and are executed by the CPU 51 or CPU 21. NS.

First, the power transfer support processing program executed in the navigation device 5 will be described.
In step 1 (hereinafter abbreviated as S) 1, the CPU 51 provides information on the current position of the vehicle, the current SOC value (remaining energy amount of the in-vehicle battery 7), and the destination and the guide route set in the navigation device 5, respectively. get. The current position of the vehicle is acquired, for example, based on the detection result of the current position detection unit 31. Further, the current SOC value is acquired based on the detection result of the battery fuel gauge 39 acquired via the in-vehicle network such as CAN. Further, the information on the destination and the guidance route set in the navigation device 5 is acquired only when the destination is set in the navigation device 5.

After that, in S2, the CPU 51 transmits the current position of the vehicle, the current SOC value, and the destination and guidance route information set in the navigation device 5 to the navigation device 5 acquired in S1. The terminal ID that identifies the source navigation device 5 is also transmitted.

Further, the processes of S1 and S2 are repeatedly executed at predetermined intervals. That is, the server device 3 grasps the current position of each vehicle, the current SOC value, the destination set in the navigation device 5, and the guidance route, respectively, based on the information periodically transmitted from each vehicle nationwide. It becomes possible. However, the processing after S1 may be performed only for the vehicle of the user who has been registered in the service for transferring the electric power in advance.

Subsequently, in S3, the CPU 51 receives the transfer confirmation information transmitted from the server device 3. Here, the transfer confirmation information is selected as a vehicle for transferring the energy (electric power) stored in the in-vehicle battery 7 to another vehicle as described later, or receives the transfer of energy (electric power) from another vehicle. This is information transmitted from the server device 3 when selected as a vehicle.

After that, in S4, the CPU 51 confirms to the user whether or not he / she agrees to transfer the electric power. For example, if the vehicle selected as the vehicle to transfer the electric power stored in the in-vehicle battery 7 to another vehicle, as shown in FIG. 7, "Do you agree to transfer the electric power?" Is displayed on the liquid crystal display 35, and the user can select whether to agree (that is, the electric power may be handed over to another vehicle) or disagree (that is, do not hand over the electric power to another vehicle). Let me. On the other hand, if you are selected as the vehicle to receive the transfer of power from another vehicle, as shown in Fig. 8, "Do you agree to receive the transfer of power?" 62 is displayed on the liquid crystal display 35, and the user is asked to select whether to agree (that is, to transfer the electric power from another vehicle) or to disagree (that is, not to transfer the electric power from another vehicle). When confirming the intention of the user whether or not he / she agrees to the transfer of electric power in S4, it is desirable to inform the user about the conditions of the transfer. For example, the amount of electric power to be transferred, the consideration obtained by transferring, the consideration to be paid by receiving the transfer, etc. are shown. In addition, information on the transferee may be provided.

After that, in S5, the CPU 51 transmits to the server device 3 the result of the intention confirmation indicating whether or not the transfer of the electric power received in S4 has been agreed. The processing after S6 is executed only when the user agrees to transfer the electric power in S4.

Next, in S6, the CPU 51 receives the information regarding the recommended transfer location transmitted from the server device 3. Here, the recommended transfer location is a location recommended for transferring electric power, and is searched and determined by the server device 3 as described later (S24 to S30). The recommended transfer place is basically a parking lot, but a place other than the parking lot may be the recommended transfer place.

Further, the information regarding the recommended transfer place received in S6 includes, for example, the name of the recommended transfer place, the position coordinates of the recommended transfer place, and the route to the recommended transfer place. Further, information (for example, vehicle type) that identifies the vehicle of the transferee may be included.

After that, in S7, the CPU 51 guides the information regarding the recommended transfer location received in S6. For example, FIG. 9 is a diagram showing an example of guiding information on a recommended transfer location using the liquid crystal display 35.

As shown in FIG. 9, the liquid crystal display 35 displays two display areas, a left screen 65 for displaying a map around the vehicle and a right screen 66 for displaying guidance information regarding the recommended transfer location.
The left screen 65 includes a map image 67 around the vehicle, a vehicle position mark 68 indicating the current position of the vehicle, and a mark 69 indicating the position of the recommended transfer location.
On the other hand, the right screen 66 includes an information display space 71 for displaying detailed information about the recommended transfer location marked on the left screen 65, and an information display space 72 for displaying information about the vehicle of the transferee. In the information display space 71, for example, the name of the recommended transfer place, the position (distance from the current position of the vehicle), the required time, and the usage fee are displayed. Further, in the information display space 72, the vehicle type and the color of the vehicle of the other party to which the electric power is transferred (or transferred) are displayed. Then, the user who visually recognizes the liquid crystal display 35 can grasp the place where the electric power is transferred and the vehicle of the other party to which the electric power is transferred (or is transferred). In addition, the recommended transfer location guided may be automatically set as a new destination or waypoint of the navigation device 5. In that case, the navigation device 5 will provide travel guidance with the recommended transfer location as the destination or waypoint.

Subsequently, in S8, the CPU 51 determines whether or not the vehicle has reached the recommended transfer location received from the server device 3 in S6. For example, when the current position of the vehicle is within a predetermined distance (for example, 50 m) from the point determined as the recommended transfer location, it is determined that the vehicle has reached the recommended transfer location. Since the current position of the vehicle can be grasped on the server device 3 side, the determination process of S8 may be performed by the server device 3.

Then, when it is determined that the vehicle has reached the recommended transfer location received from the server device 3 in S6 (S8: YES), the process proceeds to S9. On the other hand, when it is determined that the vehicle has not reached the recommended transfer location received from the server device 3 in S6 (S8: NO), it waits until it is determined that the vehicle has reached the recommended transfer location.

In S9, the CPU 51 provides parking assistance for parking the vehicle in a parking space recommended for transferring electric power. Here, in the present embodiment, when the electric power is transferred between the vehicles, the electric power is transferred by a contact type method in which the electric power cables are connected to each other's power supply ports. Therefore, it is desirable that the vehicle to which the electric power is transferred and the vehicle to be transferred are parked in close proximity to each other. Further, in a mode in which the positions of the power supply ports of the vehicle face each other (when the power supply ports are on the side surface of the vehicle) or in a mode in which the positions of the power supply ports face in the same direction (when the power supply ports are on the front surface or the rear surface of the vehicle). It is desirable to park the vehicle in a parking space.

Therefore, in S9, the CPU 51 first identifies, among the parking spaces provided in the recommended transfer location, a parking space in which the vehicle to which the power is transferred and the vehicle to be transferred can be parked next to each other. The arrangement of the parking space provided in the recommended transfer location and the current usage status of the parking space can be obtained from the parking lot management server 8. Further, the information may be acquired via the server device 3. Further, the CPU 51 also acquires the positions of the power supply ports of the vehicle to which the electric power is transferred and the vehicle to which the electric power is transferred. The position of the power supply port of the own vehicle can be obtained from the ECU or the like of the own vehicle, and the position of the power supply port of the other vehicle is obtained from the server device 3.

Next, the CPU 51 guides the user to a parking space in which the vehicle to which the electric power is transferred and the vehicle to be transferred can be parked next to each other (that is, two parking spaces adjacent to each other in an empty state). At that time, in order to park the vehicle in the parking space in such a manner that the positions of the power supply ports of the vehicle face each other or the positions of the power supply ports face the same direction, the parking direction is also guided. However, the parking space and the parking direction to be parked may not be determined by the navigation device 5, but may be determined by the server device 3 and the determined result may be delivered to the navigation device 5.

Here, FIG. 10 is a diagram showing a parking space guidance screen 81 output by the navigation device 5 in S9. As shown in FIG. 10, the parking space guidance screen 81 displays an overall view 82 of the parking lot, a vehicle position mark 83 indicating the current position of the vehicle, and an identification mark 84 identifying the parking space for which parking is recommended. Will be done. Furthermore, voice guidance is used to guide whether to park backwards or forwards. As a result, the occupant of the vehicle can easily grasp the parking position and the parking direction in which the vehicle should be parked.

Further, as the parking support in S9, vehicle control may be performed in addition to the guidance using the liquid crystal display 35 and the speaker 36 described above. For example, when applying a part or all of the vehicle's driving control to a vehicle that performs automatic driving on the vehicle side, the vehicle automatically travels to the corresponding parking space by automatic driving and is recommended for parking. You may support parking at.

As a result of providing the parking support in S9, as shown in FIG. 11, the vehicle 85 to which the electric power is transferred and the vehicle 86 to be transferred are parked next to each other in the parking space. Further, in the example shown in FIG. 11, the power supply port 87 is provided behind the left side surface of the vehicle, but by making the parking directions of the vehicle 85 to which the electric power is transferred and the vehicle 86 to be transferred opposite to each other, the power supply port 87 is provided. The positions of are opposed to each other. As a result, the power cable can be easily connected.

Next, the power transfer support processing program executed in the server device 3 will be described.
First, in S11, the CPU 21 obtains information on the current position of the vehicle transmitted from the navigation device 5, the current SOC value (remaining energy amount of the in-vehicle battery 7), and the destination and the guide route set in the navigation device 5, respectively. Receive. The terminal ID that identifies the source navigation device 5 is also received. Since the transmission of information from the navigation device 5 is repeatedly executed at predetermined intervals, as a result, the server device 3 has the current position of each vehicle nationwide, the current SOC value, and the destination set in the navigation device 5. It becomes possible to grasp each guide route. However, the processing after S11 may be performed only for the vehicle of the user who has been registered in the service for transferring the electric power in advance.

Subsequently, in S12, the CPU 21 determines whether or not there is a vehicle having a SOC value of a predetermined amount or less, based on the information received from the vehicle in S11. The predetermined amount may be a fixed value or may be a ratio to the capacity of the in-vehicle battery 7. For example, it is determined whether or not there is a vehicle in which the remaining amount of the vehicle-mounted battery 7 is 50% or less.

Then, when it is determined that there is a vehicle having an SOC value of less than or equal to a predetermined amount (S12: YES), the process proceeds to S13. On the other hand, when it is determined that there is no vehicle whose SOC value is less than or equal to the predetermined amount (S12: NO), it is presumed that there is no vehicle that requires the transfer of electric power. To finish.

In S13, the CPU 21 acquires a route to the destination of the vehicle whose SOC value is determined to be equal to or less than the predetermined amount in S12, and the current SOC value of the corresponding vehicle is equal to or less than the amount of energy required to travel to the destination. Determine if it exists. The amount of energy required to travel to the destination is calculated based on, for example, map information. Further, when the destination is not set in the navigation device 5 of the vehicle whose SOC value is determined to be equal to or less than a predetermined amount, the destination may be estimated from the past travel history, or the power transfer support processing program may be used. May be terminated. Further, when there are a plurality of vehicles whose SOC value is determined to be equal to or less than a predetermined amount in S12, the determination process of S13 is performed for each of the plurality of vehicles.

Then, when it is determined that the current SOC value of the corresponding vehicle is less than or equal to the amount of energy required to travel to the destination (S13: YES), it is presumed that there is a vehicle that requires the transfer of electric power. Therefore, it shifts to S14. On the other hand, when it is determined that the current SOC value of the corresponding vehicle is not less than or equal to the amount of energy required to travel to the destination (S13: NO), although there is a vehicle having a small SOC value, the electric power is currently supplied. Since it is presumed that there is no vehicle that requires the transfer of the power transfer, the power transfer support processing program is terminated.

Subsequently, in S14, the CPU 21 determines whether or not there is a vehicle having a SOC value of a predetermined amount or more, based on the information received from the vehicle in S11. The predetermined amount may be a fixed value or may be a ratio to the capacity of the in-vehicle battery 7. For example, it is determined whether or not there is a vehicle in which the remaining amount of the vehicle-mounted battery 7 is 50% or more.

Then, when it is determined that there are vehicles having an SOC value of a predetermined amount or more (S14: YES), the process proceeds to S15. On the other hand, when it is determined that there is no vehicle whose SOC value exceeds a predetermined amount (S14: NO), it is presumed that there is no vehicle to which the power can be transferred. finish.

In S15, the CPU 21 acquires a route to the destination of the vehicle whose SOC value is determined to be equal to or greater than the predetermined amount in S14, and the current SOC value of the corresponding vehicle is equal to or greater than the amount of energy required to travel to the destination. Determine if it exists. The amount of energy required to travel to the destination is calculated based on, for example, map information. Further, when the destination is not set in the navigation device 5 of the vehicle whose SOC value is determined to be equal to or more than a predetermined amount, the destination may be estimated from the past travel history, or the power transfer support processing program may be used. May be terminated. Further, when there are a plurality of vehicles whose SOC value is determined to be equal to or greater than a predetermined amount in S14, the determination process of S15 is performed for each of the plurality of vehicles.

Then, when it is determined that the current SOC value of the corresponding vehicle is equal to or greater than the amount of energy required for traveling to the destination (S15: YES), it is presumed that there is a vehicle to which electric power can be transferred. Therefore, it shifts to S16. On the other hand, when it is determined that the current SOC value of the corresponding vehicle is not equal to or greater than the amount of energy required to travel to the destination (S15: NO), there is a vehicle having a large SOC value, but the electric power at present. Since it is presumed that there is no vehicle that can be transferred, the power transfer support processing program is terminated.

Next, in S16, the CPU 21 determines that the SOC value is particularly equal to or less than a predetermined amount and the current SOC value is less than the amount of energy required to travel to the destination, based on the information received from the vehicle in S11. Within X km from the current position of the vehicle (that is, a vehicle that requires power supply, hereinafter referred to as "power supply required vehicle"), and is determined with respect to the direction of the destination of the power supply required vehicle based on the current position of the power supply required vehicle. An area within the directional difference (for example, ± 90 degrees) (hereinafter referred to as the first area) is set. Although the initial value of X is set to "1", it is added up to a predetermined distance (for example, 10 km) in S20 described later. For example, FIG. 12 is a diagram showing a first area 90 set in S16. As shown in FIG. 12, the first area 90 has a semicircular shape and has a radius of X km. Further, in the example shown in FIG. 12, the area within 90 degrees with respect to the direction of the destination 92 of the power-requiring vehicle with the current position of the power-requiring vehicle 91 as the base point is defined as the first area 90. Can be changed as appropriate (for example, 45 degrees or 120 degrees). However, if the orientation difference is too narrow, the recommended transfer location cannot be found, and if the orientation difference is too wide, the burden on the user to move to the recommended transfer location increases.

After that, in S17, the CPU 21 determines that the SOC value is particularly equal to or higher than a predetermined amount and the current SOC value is larger than the amount of energy required to travel to the destination, based on the information received from the vehicle in S11. Within Xkm from the current position of the vehicle (that is, a vehicle whose power can be transferred to another vehicle, hereinafter referred to as "transfer vehicle"), and in the direction of the destination of the transfer vehicle based on the current position of the transfer vehicle. On the other hand, an area within a predetermined azimuth difference (for example, ± 90 degrees) (hereinafter referred to as a second area) is set. Since the details are the same as in S16, the details will be omitted. Further, when there are a plurality of combinations of the power supply required vehicle and the transfer vehicle, the processing after S16 is executed for each combination.

Next, in S18, the CPU 21 determines whether or not the first area set in S16 and the second area set in S17 overlap. In particular, it is desirable to determine whether or not the area overlaps by a predetermined area (for example, 1 km ^{2) or more.}

Then, when it is determined that the first area set in S16 and the second area set in S17 overlap (S18: YES), the process proceeds to S21. On the other hand, when it is determined that the first area set in S16 and the second area set in S17 do not overlap (S18: NO), the process proceeds to S19.

In S19, the CPU 21 determines whether or not X is the upper limit value. Although the initial value of X is "1", it is sequentially added in S21 described later. The upper limit of X is, for example, 10 (km).

Then, when it is determined that X is the upper limit value (S19: YES), it is determined that there is no recommended place for transferring the electric power between the target power-requiring vehicle and the transfer vehicle. , End the power transfer support processing program. On the other hand, when it is determined that X is not the upper limit value (S19: NO), the value of X is added by "+1" (S20), and the process returns to S16. As a result, the first area set in S16 and the second area set in S17 are each expanded.

Subsequently, in S21, the CPU 21 transmits the transfer confirmation information to the power supply required vehicle and the transfer vehicle. Then, the navigation device 5 of the power-requiring vehicle and the transfer vehicle that has received the transfer confirmation information confirms the intention of the user as to whether or not he / she agrees to the transfer of electric power as described above (S4, FIG. 7, FIG. 8).

After that, in S22, the CPU 21 receives the result of the intention confirmation indicating whether or not the transfer of the electric power transmitted from the power-requiring vehicle and the transfer vehicle is agreed.

In S23, the CPU 21 determines whether or not both the users of the power-requiring vehicle and the transfer vehicle have agreed to the transfer of electric power. Then, when it is determined that both the users of the power-requiring vehicle and the transfer vehicle have agreed to the transfer of electric power (S23: YES), the process proceeds to S24. On the other hand, if it is determined that at least one user of the power-requiring vehicle and the transfer vehicle does not agree to the transfer of electric power (S23: NO), the electric power cannot be transferred, so the electric power transfer support processing program. To finish. However, the power supply required vehicle or the transferred vehicle that did not agree may be changed to another candidate vehicle, and the processing after S16 may be performed again.

In S24, the CPU 21 searches within the overlapping area where the first area and the second area overlap, and searches for a recommended transfer location recommended for transferring power between the power supply required vehicle and the transfer vehicle. In the present embodiment, a parking lot provided with a parking space is set as the recommended transfer location. Not only a separate parking lot but also a parking lot attached to the facility may be included. Further, parking lot information regarding parking lots nationwide is stored in the server-side map DB 12, and the CPU 21 searches for a recommended transfer location using the parking lot information read from the server-side map DB 12.

Subsequent processing of S25 to S29 is executed for each parking lot searched in S24, that is, for all parking lots in the overlapping area where the first area and the second area overlap. Then, after the processes of S25 to S29 are executed for all the parking lots in the overlapping area where the first area and the second area overlap, the process shifts to S30.

First, in S25, the CPU 21 calculates the cruising distance of the power-requiring vehicle (distance that can be traveled without charging at the current SOC) based on the SOC value of the power-requiring vehicle. Then, it is determined whether or not the distance required for moving the power-requiring vehicle from the current position of the parking lot to be processed is less than the cruising distance. The transfer vehicle may be determined in the same manner.

Then, when it is determined that the distance required for moving the power-requiring vehicle from the current position of the parking lot to be processed is less than the cruising distance (S25: YES), the process proceeds to S26. On the other hand, when it is determined that the distance required to move the power-requiring vehicle from the current position of the parking lot to be processed is not less than the cruising distance (S25: NO), the parking lot to be processed is of electric power. It is determined that it is not suitable as a place to transfer, and after changing the parking lot to be processed, the process returns to S25.

Next, in S26, the CPU 21 determines whether or not information regarding the current usage status of the parking space for the parking lot to be processed can be acquired from the parking lot management server 8.

Then, when it is determined that the information regarding the current parking space usage status of the parking lot to be processed can be obtained from the parking lot management server 8 (S26: YES), the process proceeds to S27. On the other hand, when it is determined that the information on the current parking space usage status of the parking lot to be processed cannot be obtained from the parking lot management server 8 (S26: NO), the process proceeds to S28.

In S27, the CPU 21 acquires information on the current parking space usage status of the parking lot to be processed from the parking lot management server 8 and determines whether or not there are adjacent parking spaces that are vacant. Here, in the present embodiment, when the electric power is transferred between the vehicles, the electric power is transferred by a contact type method in which the electric power cables are connected to each other's power supply ports as shown in FIG. Therefore, it is desirable to park the vehicle requiring power supply and the vehicle to be transferred close to each other. Therefore, one of the conditions of the recommended transfer place is to provide a parking space in which the power-requiring vehicle and the transfer vehicle can be parked next to each other.

Then, when it is determined that there are parking spaces that are adjacent to each other and are vacant (S27: YES), the parking lot to be processed is set as a candidate for the recommended transfer location (S29). On the other hand, when it is determined that there is no vacant parking space adjacent to the parking lot to be processed (S27: NO), the parking lot to be processed is not suitable as a place for transferring power. After changing the parking lot to be processed, the process returns to S25.

On the other hand, in S28, the CPU 21 acquires the number of parking spaces provided in the parking lot to be processed from the server-side map DB 12, and determines whether or not the number of parking spaces is a predetermined number (for example, 30) or more. Here, in the present embodiment, when the electric power is transferred between the vehicles, the electric power is transferred by a contact type method in which the electric power cables are connected to each other's power supply ports as shown in FIG. Therefore, it is desirable to park the vehicle requiring power supply and the vehicle to be transferred close to each other. In a parking lot with a lot of parking spaces, it is highly likely that the power-requiring vehicle and the transfer vehicle can be parked next to each other. Let's do it.

When it is determined that the number of parking spaces provided in the parking lot to be processed is equal to or greater than a predetermined number (S28: YES), the parking lot to be processed is set as a candidate for the recommended transfer location (S29). On the other hand, when it is determined that the number of parking spaces provided in the parking lot to be processed is less than the predetermined number (S28: NO), the parking lot to be processed is unsuitable as a place for transferring power. After making a determination and changing the parking lot to be processed, the process returns to S25.

After that, in S30, the CPU 21 executes the processes of S25 to S29 for all the parking lots in the overlapping area where the first area and the second area overlap, and as a result, finally selects as a candidate for the recommended transfer location. Among the parking lots (S29), the candidate having the smallest total value of the distance from the current position of the power-requiring vehicle and the distance from the current position of the transfer vehicle is determined as the recommended transfer location. The distance to be determined may be a straight line distance or a road distance.

Next, in S31, the CPU 21 acquires information about the parking lot determined as the recommended transfer location in S30. Specifically, the name of the recommended transfer place, the position coordinates of the recommended transfer place, and the information about the route to the recommended transfer place are acquired.

Subsequently, in S32, the CPU 21 transmits information about the parking lot determined as the recommended transfer location acquired in S31 to the navigation device 5 of the power-requiring vehicle and the transfer vehicle, respectively. As a result, as described above, the users of the power-requiring vehicle and the transfer vehicle are informed about the recommended transfer location (S7, FIG. 9). In addition, after the power-requiring vehicle and the transfer vehicle reach the recommended transfer location, the support information required to park the vehicle in the parking space recommended for power transfer (for example, power supply provided in the vehicle). We will also provide the location of the mouth and the parking space that is currently vacant).

As described in detail above, in the computer program executed by the inter-vehicle energy transfer support system 1, the server device 3, and the server device 3 according to the present embodiment, the energy is stored in the in-vehicle battery 7 of one vehicle between a plurality of vehicles. By transferring the existing energy to the other vehicle, it assists in supplying power to the in-vehicle battery of the other vehicle. Specifically, the current positions of a plurality of vehicles are acquired (S11), and a recommended location for transferring energy between the plurality of vehicles is searched based on the current positions of the plurality of vehicles (S24 to S30). ), Information on recommended locations for transferring energy searched for is provided to multiple vehicles (S32), so appropriate locations for transferring energy between vehicles are provided as support information. It is possible, and by directing the vehicle to the provided location, it is possible to ensure the transfer of energy between the vehicles. As a result, it becomes possible to appropriately support the transfer of energy between a plurality of vehicles.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various improvements and modifications can be made without departing from the gist of the present invention.
For example, in the present embodiment, a parking lot is particularly selected as the recommended transfer place, but it does not necessarily have to be a parking lot as long as there is a space where the vehicle can be parked. Therefore, it is possible to set a facility other than the parking lot (for example, a commercial facility) as the recommended transfer location. Further, the recommended transfer location may not be set for each parking lot, but may be set for each parking space for more detailed parking of the car. In that case, for example, it is possible to search for parking spaces that are adjacent to each other and are vacant in the overlapping overlapping areas of the first area and the second area as recommended transfer locations.

In addition, the recommended transfer location may be searched in consideration of the time required for the transfer of electric power. For example, if the time required to transfer power is greater than or equal to the threshold, the parking lot attached to the commercial facility or the parking lot adjacent to the commercial facility is preferentially searched as the recommended transfer location so that the user can kill the time. It is possible. You may also search for a recommended transfer location in consideration of the parking lot format. For example, even if it is a parking lot, if it is a multi-story parking lot, it is difficult to transfer electric power, so that it may be a condition that it is a flat parking lot.

Further, in the present embodiment, the transfer of electric power is described on the premise that there is a charge, but it does not matter whether it is free or paid. Further, the transfer of energy between vehicles can be performed not only when the vehicle on the transfer side and the vehicle on the transfer side are one-to-one, but also on a one-to-many basis. Further, the energy may be transferred directly between the vehicles, or indirectly, for example, via a charging facility.

Further, in the present embodiment, an example in which power is transferred by a contact type method in which power cables are connected to each other's power supply ports is described, but it is also possible to transfer power by non-contact (wireless) power transmission. Examples of non-contact power transmission include an "electromagnetic induction method" using electromagnetic induction and a "magnetic field resonance method" using the phase adjustment phenomenon of the magnetic field generated when the coil resonates. As shown in FIG. 13, by providing the power transmission coil 101 for power transmission and the power reception coil 102 for power reception to the vehicle 4, the transfer of electric power between the vehicles by the above-mentioned "electromagnetic induction method" and "magnetic field resonance method" can be performed. It will be possible. Further, when the vehicle is parked at the recommended transfer location, it is desirable to provide support so that the power transmission coil 101 and the power reception coil 102 are parked so as to face each other as shown in FIG.

Further, in the present embodiment, in the power transfer support processing program shown in FIGS. 5 and 6, the execution body of the processing (S16 to S30) related to the search for the recommended transfer location is the server device 3, but the navigation device 5 is one. It may be configured to execute a part or all. When the navigation device 5 performs these processes, the navigation device 5 corresponds to the inter-vehicle energy transfer support device of the present invention.

Further, instead of the navigation device 5, it is also possible to configure the inter-vehicle energy transfer support system 1 with another device having a traveling guidance function. For example, an in-vehicle device other than the navigation device 5, a mobile phone, a smartphone, a tablet terminal, a personal computer, or the like is possible.
