  The navigation system 1 is composed of a center 3 and each vehicle 2 capable of wireless communication with the center 3. In the navigation system 1, when a destination is set for each vehicle 2 by an occupant (driver or the like), the destination is transmitted from the vehicle 2 to the center 3, and a route search is performed at the center 3. Further, in the navigation system 1, route information is transmitted from the center 3 to the vehicle 2, and the vehicle 2 provides route information to the occupant. In particular, in the navigation system 1, in order to actively attract the vehicle 2 having surplus power to an area where power is insufficient, the center 3 determines a route for selling power passing through the area where power is insufficient. The route information that can be sold by the vehicle 2 is also provided to the occupant.

  The vehicle 2 includes a motor as a drive source and is equipped with a battery (not shown) capable of charging and discharging electric power with the outside. For example, the vehicle 2 is a plug-in hybrid vehicle or an electric vehicle. Further, the vehicle 2 has a wireless communication function with the center 3. In the vehicle 2, when the occupant sets a destination (including a waypoint), the destination is transmitted to the center 3, and when the route information from the center 3 to the destination is received, the route information is displayed to the occupant. To do. For this purpose, the vehicle 2 includes a communication device 20, a vehicle state sensor 21, a destination setting unit 22, and a route display unit 23. In the present embodiment, the vehicle state sensor 21 corresponds to the remaining battery charge acquisition means described in the claims.

  The vehicle 2 may have not only a route information display function, but also a function for selecting a route desired by the occupant from the displayed information of a plurality of routes and a route guidance function for the route.

  The communication device 20 is a communication device for performing wireless communication with the center 3 and is, for example, a DCM (Date Communication Module). The information transmitted by the communication device 20 includes, for example, identification information of the vehicle 2, information detected by the vehicle state sensor 21, and information on the destination and waypoint set by the destination setting unit 22. Information received by the communication device 20 includes, for example, route information. Information set by the destination setting unit 22 may be transmitted when set by the occupant, and information detected by the vehicle state sensor 21 may be transmitted together with the destination information or the like. It may be sent every hour.

  The vehicle state sensor 21 is various sensors for detecting the vehicle state. As the vehicle state sensor 21, for example, a vehicle speed sensor for detecting the vehicle speed, a GPS [Global Positioning System] antenna and an arithmetic unit for detecting the current position and traveling direction, and an SOC for detecting the remaining charge amount of the battery There is a [State Of Charge] sensor. In addition, about the detection of a present position and advancing direction, the detection by not only GPS but the hybrid navigation which combined GPS and self-contained navigation may be sufficient.

  The destination setting unit 22 is for a vehicle occupant to set a destination, a waypoint, and the like. For example, the destination setting unit 22 uses a display having an operation function such as a touch panel or a joystick.

  The route display unit 23 is a display unit for displaying route information, and is, for example, an in-vehicle display. The information displayed on the route display unit 23 is route information transmitted from the center 3 and information on a plurality of route candidates to the destination. As information of a plurality of route candidates, for example, highway priority route information, general road priority route information, distance priority route information, time priority route information, route information that can be sold via power, via There is information on routes where electricity can be sold at different locations. The route information includes, for example, road information along the route, travel distance, travel time, profit amount from power sale and position information of power equipment capable of power sale in the case of a route that can sell power.

  The center 3 is a center that provides various services to the vehicle 2, for example, a center operated by an automobile company. The center 3 has a wireless communication function with each vehicle 2. Further, the center 3 has a function of collecting power supply and demand for each region. As one of the services performed at the center 3, when a destination is received from the vehicle 2, a plurality of route information to the destination is searched, and the searched plurality of route information is transmitted to the vehicle 2. In particular, in route search, in addition to normal route search such as highway priority and general road priority, a route that can be sold through a power-deficient area is also searched. For this purpose, the center 3 includes a communication device 30, a map database 31, a power supply / demand database 32, a route search unit 33, and a power shortage route determination unit 34, and the databases 3 and 32 and the processing units 33 and 34 are center 3. Configured on the computer. In the present embodiment, the power supply / demand collection function for each region in the center 3 corresponds to the power demand acquisition means described in the claims, and the route search unit 33 and the power shortage route determination unit 34 include This corresponds to route information setting means described in the claims.

  The communication device 30 is a communication device for performing wireless communication with each vehicle 2. Information transmitted by the communication device 30 includes, for example, route information. Information received by the communicator 30 includes, for example, identification information of the vehicle 2, various information on the vehicle state of the vehicle 2, and information on destinations and waypoints set by passengers of the vehicle 2.

  The map database 31 is a database that stores various map data. The map data includes map data for route search, and includes node information and link information for route search. This link information includes at least cost information. The cost is set based on the link distance, travel time, road type, road width, and the like. The cost indicates that the smaller the value, the higher the merit. Therefore, in the route search, the total costs of the route candidates are compared, and a route candidate having a small total cost is selected. The stored map data is updated regularly or every time the data is updated.

  The power supply / demand database 32 is a database in which data on the amount of power demand and supply in each region, range information on each region, position information on power facilities that can be sold and charged in the region, and the like are stored. As the region, for example, a region in a municipal unit or a region in a distribution area unit in each distribution facility of an electric power company. Examples of power facilities that can sell and charge power include power facilities that are provided in parking lots such as charging stations, shopping centers, restaurants, and supermarkets. The stored power demand and supply data for each region is transmitted from a power company or a national power management organization by a wired or wireless communication device provided in the center 3, and is transmitted at regular intervals (for example, 1 Updated every hour, every 30 minutes, every 10 minutes). Further, the stored range information of each area and the position information of the power equipment that can sell power in the area are updated regularly or every time the data is updated. In areas where there is more demand than supply, power is insufficient and power supply is required.

  The route search unit 33 is a processing unit that searches for a route from the vehicle 2 to the destination. Specifically, the route search unit 33 starts a normal route search process when a destination (a route point may be set) and a current position are transmitted from an arbitrary vehicle 2 and starts the current position. The search is made for candidates of a plurality of routes from the route to the destination (routes that pass through when a route is set). Then, the route search unit 33 calculates the total cost for each route candidate, compares the total cost of all route candidates, and selects the top n route candidates having the smallest total cost. Here, for each priority item such as highway priority, general road priority, distance priority, and time priority, one or a plurality of route candidates are selected in ascending order of the total cost.

  The power shortage route determination unit 34 is a processing unit that determines, from the top n route candidates searched by the route search unit 33, a route candidate capable of selling power that passes through the power shortage region. Specifically, in the power shortage route determination unit 34, when the route search unit 33 searches for a route candidate, the route candidate having the longest distance to the destination is selected from the route candidates, and the vehicle traveled on the route with the longest distance. In this case, the maximum amount of power required to reach the destination is calculated. Then, the power shortage path determination unit 34 determines whether or not the remaining charge amount of the battery transmitted from the vehicle 2 is sufficiently larger than the maximum power amount required up to the destination. When the remaining charge amount of the battery is sufficiently larger than the maximum power amount required until the destination, surplus power remains in the battery even after traveling to the destination, so that power can be supplied in the middle. On the other hand, if the remaining charge of the battery is less than or equal to the maximum amount of power required to reach the destination, it is impossible to supply power. Do not judge candidates.

  In the case where the remaining charge amount of the battery of the vehicle 2 is sufficiently larger than the maximum amount of power required to reach the destination, the power shortage path determination unit 34 determines the peripheral area from the current position of the vehicle 2 to the destination from the power supply / demand database 32. An area where power is insufficient in (for example, a target area for which a route search is performed by the route search unit 33) is extracted. Then, the power shortage route determination unit 34 compares the route candidate passage area with the power shortage region for each of the top n route candidates searched by the route search unit 33, and sets the route candidate passage region as a power shortage region. Is included (that is, whether the route candidate route passes through the power shortage region). When there is a route candidate including a power shortage area, the vehicle 2 travels along the route, so that power can be supplied and sold in the power shortage area. In addition, when there is no power shortage area in the peripheral area from the current position of the vehicle 2 to the destination, the route candidate capable of selling power passing through the power shortage area is not determined.

  In the case of the example shown in FIG. 2, the power shortage area A exists in the peripheral area from the current position O to the destination D. In this example, three route candidates R1, R2, and R3 were searched as route candidates from the current position O to the destination D by the normal route search process. Of the three route candidates R1, R2, and R3, the route of the route candidate R3 passes through the power shortage area A, so the route candidate R3 is determined as a route candidate including the power shortage area.

  When there is a route candidate including the power shortage area, the power shortage path determination unit 34 calculates the amount of power necessary to reach the destination when traveling on the route candidate route including the power shortage area, and the power amount The surplus power (the amount of power that can be sold) of the vehicle 2 is calculated based on the remaining charge amount of the battery of the vehicle 2 and the profit amount when the surplus power is sold is calculated. In addition, the power shortage route determination unit 34, for each other route candidate that does not include the power shortage area, when traveling on a route candidate route that includes the power shortage area, other route candidates that do not include the power shortage area. Calculate the extra cost compared to when driving. As this calculation method, for example, the travel distance to the destination in the other route not including the power shortage area is subtracted from the travel distance to the destination in the route including the power shortage area, and the travel distance The cost (amount) required to travel the difference (extra travel distance due to traveling on a route including a power shortage area) is calculated. In addition to the travel distance, the cost may be calculated based on a difference in travel time, presence or absence of a toll road, and the like. Then, the power shortage path determination unit 34 determines whether or not the profit amount when surplus power is sold is larger than the extra cost. If the amount of profit when surplus power is sold is greater than the extra cost, a positive profit can be obtained by selling power, so that it can be presented as a route candidate that can be sold. On the other hand, if the amount of profit when surplus power is sold is less than the extra cost, a positive profit cannot be obtained by selling power, and therefore it cannot be presented as a route candidate that can be sold.

  In the case where the profit amount in the case of selling power is higher than the cost that is extra than other route candidates, the power shortage route determination unit 34 determines a route candidate including a power shortage region as a route candidate capable of selling power. Here, for all other route candidates that do not include the power shortage area, there may be a route candidate that can be sold when the profit amount from power sale is higher than the extra cost, or there is a power shortage Among all other route candidates that do not include the region, if some (at least one) other route candidates have a profit amount from the power sale greater than the extra cost, they are determined as route candidates that can be sold. Also good.

  When there is a route candidate capable of selling power, the power shortage route determination unit 34 calculates the profit amount obtained by selling power. As this calculation method, for example, an amount obtained by subtracting an extra cost (amount) from the profit amount when power is sold, or the profit amount itself when power is sold may be used. Further, the power shortage path determination unit 34 extracts position information of power equipment that can sell power in the power shortage area from the power supply and demand database 32. Then, the power shortage route determination unit 34 uses the communication device 30 to provide information on the route candidates that can be sold (road information, travel distance, travel time, etc.), information on the amount of profit from power sale, and within the power shortage area. The position information of the electric power equipment that can be sold at 1 and information on other route candidates that do not include the power shortage area are transmitted to the vehicle 2. On the other hand, when there is no route candidate that can be sold, the power shortage route determination unit 34 uses the communication device 30 to transmit each information of the top n route candidates extracted by the route search unit 33 to the vehicle 2 as it is. .

  In addition, when a waypoint is set on the way, the following process may be performed by the power shortage path determination unit 34. The power shortage path determination unit 34 extracts from the map database 31 a transit point similar to a transit point existing in the power shortage region in the peripheral region from the current position to the destination. As this extraction method, for example, a facility similar to a transit point facility set by a passenger is extracted. When the stopover is a restaurant, a similar restaurant in the power shortage area is extracted as a similar stopover, and when the stopover is a shopping center, a similar shopping center in the power shortage area is extracted. When a similar waypoint can be extracted, the power shortage route determination unit 34 uses a route that passes through the similar route point (the route search unit 33 searches for a route that passes through the similar route point) as a route candidate that can be sold. decide. For this route candidate capable of selling power, the profit amount obtained by selling power is calculated in the same manner as described above, and the benefit of traveling on a route passing through a similar waypoint is presented. This process may be performed when it is determined that there are no route candidates that can be sold in the top n route candidates. Moreover, it is good to extract the transit place with the electric power equipment which can be sold as a similar transit place.

  In the case of the example shown in FIG. 3, the waypoint P is set in the middle of the current position O and the destination D, and the power shortage area A exists in the peripheral area from the current position O to the destination D. In the case of this example, the route candidate R4 is searched for as a route candidate passing through a transit point P (for example, a Western restaurant) from the current position O to the destination D by a normal route search process. Since this route candidate R4 does not pass through the power shortage region A, a route point P ′ similar to the route point P in the power shortage region A (for example, a Western restaurant in the power shortage region A) is extracted and passed through A route candidate R5 passing through the place P ′ is searched. Then, the route candidate R4 passing through the route point P is presented to the occupant, and the route candidate R5 passing through the route point P 'similar to the route point P is presented together with the profit from the power sale.

  Note that the process in the power shortage path determination unit 34 may be performed only when the passenger of the vehicle 2 has enough time (for example, when it is predicted that a break such as a meal is included on the way to the destination). In this way, processing can be reduced by performing processing only when there is time to spare, and it is possible to reduce the processing load. Can be reduced. Also, if there are multiple power shortage areas in the surrounding area from the current position to the destination, perform the above processing for each power shortage area, and there are route candidates that can sell electricity that include each power shortage area. Presents profits from electric power sales, travel distance, etc. so that each route candidate can be compared.

  With reference to FIG. 1, the flow of operations in the navigation system 1 will be described. In particular, the flow of processing in the center 3 will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart showing the flow of processing in the center of FIG.

  In each vehicle 2, the vehicle position sensor 21 detects the current position, the remaining battery charge, and the like at regular intervals. In each vehicle 2, when the occupant sets the destination by the destination setting unit 22, the communication device 20 transmits information such as the destination, the current position, and the remaining charge amount of the battery to the center 3. In the center 3, information transmitted from each vehicle 2 is received by the communication device 30. The center 3 normally waits for a destination from the vehicle 2 and starts route search when the destination is received (S1).

  When a route search is started in S1 and a route candidate is searched, in the center 3, the remaining charge amount of the battery is necessary for traveling to the destination based on the remaining charge amount of the battery and the travel distance of each route candidate. It is determined whether or not it is sufficiently larger than the amount of power (S2). When it is determined in S2 that the remaining charge amount is not sufficiently larger than the amount of power required for traveling to the destination, the center 3 stops the determination process of the route candidate that can be sold through the power shortage area, The top n route candidates are extracted by a normal route search process (S3), and the communication device 30 transmits the route information of the n route candidates to the corresponding vehicle 2 (S4).

  When it is determined in S2 that the remaining charge amount is sufficiently larger than the amount of power required for traveling to the destination, the center 3 extracts the top n route candidates by the normal route search process (S5). Then, the power shortage area existing in the peripheral area from the power supply and demand database 32 to the destination is extracted. Then, the center 3 compares whether or not there is a power shortage area in the passing area of the n route candidates (S6), and determines whether there is a route candidate including the power shortage area (S7). . When it is determined in S7 that there is no route candidate including the power shortage area, the center 3 transmits the route information of n route candidates extracted by the normal route search process by the communication device 30 to the corresponding vehicle 2. (S4).

  When it is determined in S7 that there is a route candidate including the power shortage area, the center 3 travels on the route candidate route including the power shortage area more than when traveling on another route candidate route. While calculating this cost, the profit at the time of driving | running and selling the route candidate containing a power shortage area is calculated. Then, the center 3 determines whether or not the profit from the power sale is higher than the extra cost (S8). If it is determined in S8 that the profit from the power sale is not higher than the extra cost, the center 3 uses the route information of the n route candidates extracted by the normal route search process by the communication device 30 as the corresponding vehicle 2. (S4).

  When it is determined in S8 that the profit from the power sale is higher than the extra cost, the center 3 determines a route candidate including the power shortage area as a route candidate that can be sold. Then, in the center 3, in addition to the route information of the route candidates that can be sold by the communication device 30 including the power shortage area, the profit amount from the power sale and the route information of other route candidates are transmitted to the corresponding vehicle 2 ( S9).

  When the information on the n route candidates transmitted in S4 is received, the vehicle 2 that transmitted the destination displays information such as the travel distance and travel time of each route candidate on the route display unit 23. In addition, when the information on the route candidate that can be sold including the power shortage area transmitted in S9 and the information on the other route candidates are received, the vehicle 2 that has transmitted the destination can sell power on the route display unit 23. It displays information such as travel distance and travel time of route candidates and profits from power sale, and displays information such as travel distance and travel time of other route candidates. The occupant selects a route to travel based on information on a plurality of route candidates displayed on the route display unit 23.

  According to this navigation system 1, when there is surplus power in the battery of the vehicle 2, it is possible to provide information on route candidates that can be sold through the power shortage area to passengers of the vehicle 2. A certain vehicle 2 can be actively attracted (guided) to an area where power is insufficient, and surplus power of the battery can be used (supplied) efficiently. By attracting the vehicles 2 with surplus power to the power shortage area, it is possible to efficiently supply power to the power shortage area and improve the power supply / demand balance between the areas. In addition, it becomes possible for a vehicle occupant to select a route for selling power, which is advantageous in terms of money, and can obtain profits from selling electricity.

  Moreover, according to the navigation system 1, the vehicle occupant can confirm the financial merit by presenting the profit from the power sale for the route candidates that can be sold. In addition, according to the navigation system 1, the route candidate that can be sold is determined in consideration of the extra cost and the profit in the case of selling power than when traveling on another route candidate. When a vehicle occupant selects a route candidate that can sell power and sells power, a financial advantage can be obtained. Further, according to the navigation system 1, a route point similar to the case where a route point is set is extracted from a power shortage area, a route candidate that can be sold is searched, and the route candidate that can be sold is sold. By presenting it together with the benefits of electricity, vehicles with surplus power in the battery can be more actively attracted to regions with insufficient power. In addition, according to the navigation system 1, the processing can be efficiently performed by the configuration in which each processing is performed by the center 3 that can easily collect the power supply and demand in each region. It does not need a function to collect electricity supply and demand.

  As mentioned above, although embodiment which concerns on this invention was described, this invention is implemented in various forms, without being limited to the said embodiment.

  For example, in the present embodiment, the present invention is applied to a navigation system including a vehicle and a center. However, the present invention can also be applied to a system having another configuration. For example, a system that performs all processing in the vehicle may be configured. Processing performed at the center by a portable terminal such as a smartphone possessed by the passenger may be configured, and the system may be configured by the vehicle and the portable terminal.

  In this embodiment, the route search is performed and applied to a navigation system that provides route information based on the route search. However, the route search function is not provided, and the remaining battery charge and the power demand for each region are determined. You may apply to the information provision system which provides the route information based on.

  Moreover, although applied to the vehicle provided with the battery which can be charged / discharged outside in this Embodiment, it is applicable to the vehicle provided with the battery which can be discharged at least outside. For example, in the case of a vehicle including a power generation device such as a fuel cell or a solar panel, it is possible to charge the battery with the power generated by the power generation device, so that there is no need for an external charging function.

  In this embodiment, the remaining charge amount of the battery is the current remaining charge amount detected by the sensor. However, the current remaining charge amount is estimated by predicting the future power generation amount by the regeneration or power generation device up to the point where power is sold. It is good also as the remaining charge amount of the battery in which the predicted power generation amount is added to the amount.

  In the present embodiment, the route candidate that can sell power is set in consideration of the cost that is extra than other route candidates and the profit from power sale, but the cost and sale that are extra than other route candidates are set. Route candidates that can sell electricity may be set without taking into account the benefits of electricity.

  Further, in the present embodiment, a cost (amount) that is extra than other route candidates is calculated, and it is determined whether or not the route candidate can be sold by comparing the cost with the profit amount from the power sale. However, it may be determined whether or not the route candidate is capable of selling power by comparing the burden caused by changing the traveling purpose and the profit from power sale when traveling on the route capable of selling power.

  In the present embodiment, when there is surplus power in the battery, the top n route candidates with the lowest total cost are searched for by the normal route search process, and the n route candidates pass through the power shortage area. Although the route candidate that can sell power is set depending on whether or not there is a route, other methods may be used as a method of setting a route candidate that can be sold when there is surplus power in the battery. The route candidates that can be sold may be set depending on whether or not there is a route that passes through the power shortage area among all the route candidates that can be searched by the route search processing of It is also possible to search for the top n route candidates having a smaller size and to search for route candidates that pass through the power-deficient area.
