  As a means for the problem of running out of battery in an electric vehicle, Patent Document 1 discloses a navigation system when the voltage of a battery (that is, a battery) reaches a lower limit value at which a motor driving an electric vehicle and a navigation system can operate. A technique for transmitting the current position information of the own vehicle acquired in (1) to a portable terminal owned by a driver by wired or short-range wireless communication is disclosed.

JP 2011-188727 A

  With the technique disclosed in Patent Document 1, when the vehicle is out of battery and cannot travel, the current position information transmitted to the mobile terminal can be transmitted to the rescue request destination. However, it is necessary for the driver to contact the rescue request after checking the rescue request telephone number or searching for and selecting the rescue request destination registered in the mobile phone. There was a problem that it took.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an apparatus for an electric vehicle that makes it possible to reduce time and effort for a driver in dealing with a battery running out of the electric vehicle. And providing an electric vehicle system.

  In the electric vehicle apparatus of the present invention, the power receiving side communication means for performing the inter-vehicle communication with the vehicles around the own vehicle, including the current position of the own vehicle and requesting the power supply to the battery of the own vehicle. To send by. Therefore, it becomes possible to notify the current position of the vehicle to the drivers of an unspecified number of other vehicles around the vehicle at the same time and make a power supply request. Therefore, it is possible to negotiate the power supply one by one by calling the contact information registered in the mobile phone, or to negotiate the power supply one by one to the driver of another vehicle existing within the range visible to the user. You can save time and effort.

  In the electric vehicle system according to the present invention, when the power supply vehicle device of the power supply vehicle that has received the power supply request information transmitted from the electric vehicle supplies power to the battery of the electric vehicle at the current position of the electric vehicle, When the first securing determination means determines that a sufficient amount of remaining charge on the power supply side can be secured for the power supply vehicle to reach the destination, the user of the power supply vehicle is notified that the power supply request has been made. Let's do it. Then, when an operation input for accepting the power supply request is received by the request receiving means, reception information indicating that the power supply request has been received is transmitted by inter-vehicle communication by the power supply side communication means.

  According to this, since the power supply vehicle apparatus automatically determines whether or not the power supply vehicle has enough power to supply power to the electric vehicle, the power consumption when supplying power to the electric vehicle is determined. It is not necessary to determine whether there is enough power to supply power by making a trial calculation between the drivers on both sides. Therefore, the driver on the power supply vehicle side can quickly determine whether or not to accept the power supply request. In addition, this makes it possible to reduce the waiting time for power supply by the user of the electric vehicle.

In addition, regarding the facility, the types, names, and address data of various facilities are included. The character data is data for displaying a place name, a facility name, a road name, etc. on a map, and is associated with coordinate data corresponding to the position to be displayed.

  The display device 4 is mounted in the vehicle so as to be fixed or portable, is used in the vehicle interior, and displays text and images. The display device 4 is capable of full color display, for example, and can be configured using a liquid crystal display, an organic EL display, a plasma display, a head-up display, or the like. As the display device 4, for example, a dedicated display may be mounted, or a display such as an in-vehicle navigation device or a so-called display audio (DA) may be used. The audio output device 5 includes a speaker or the like, and outputs audio according to instructions from the control device 12.

  As the operation switch group 6, for example, a mechanical switch, a touch switch integrated with the display device 4, a remote operation switch, or the like is used, and an operation instruction for various functions is given to the control device 12 by the switch operation.

  The charge monitoring unit 7 monitors a state of charge (SOC) that is a ratio of the remaining charge to the charge capacity of the traveling battery 8 that supplies electric power to a motor as a traveling drive source of the host vehicle. In addition, the battery 8 for driving | running | working corresponds to the battery of a claim.

  The wireless communication device 11 of the in-vehicle device 1 includes a transmission / reception antenna, and performs transmission / reception of information (that is, vehicle-to-vehicle communication) to / from other vehicles existing around the vehicle position by wireless communication without using a telephone network. Do. It is assumed that the communication range of inter-vehicle communication is limited to a predetermined range (preferably a radius of about several hundred m to 1 km).

  For example, in the case of wireless communication using 700 MHz band radio waves, vehicle-to-vehicle communication is performed with other vehicles existing in a radius range of, for example, about 1 km around the position of the vehicle, and 5.9 GHz band radio waves. In the case of wireless communication using the vehicle, vehicle-to-vehicle communication is performed with another vehicle that exists in a range of, for example, a radius of about 500 m centered on the own vehicle position.

  The control device 12 of the in-vehicle device 1 includes a known CPU, a memory such as a ROM, a RAM, and an EEPROM, an I / O, and a bus line (none of which is shown) for connecting these components. . The control device 12 relates to processing as a navigation function and power supply based on various information input from the wireless communication device 11, the position detector 2, the map data input device 3, the operation switch group 6, and the charge monitoring unit 7. Various processes such as processes are executed.

  The control device 12 performs a route search process for searching for a recommended route when the electric vehicle travels between the set points. In the route search process, a recommended route that satisfies preset conditions such as distance priority and time priority is searched using a known search method. For example, in the route search process, when a destination is input from the operation switch group 6, the current position and the destination of the own vehicle are set, and a recommended route from the current position of the own vehicle to the destination is searched. As the current position of the host vehicle, the current position of the host vehicle detected by the position detector 2 may be set.

  Moreover, in the control apparatus 12, after performing a route search process, a route guidance process is performed. In the route guidance process, an electronic map indicating the recommended route searched in the route search process and the current position of the host vehicle is sequentially displayed on the display device 4, and guidance voice for supporting traveling on the recommended route is sequentially received from the voice output device 5. Route guidance is performed by outputting. The electronic map may be configured to be displayed on the display device 4 using the map data input from the map data input device 3.

  The process related to the power supply executed by the control device 12 is a control device of the in-vehicle device 1 of the electric vehicle (hereinafter referred to as an electric shortage vehicle) that performs a power supply request for requesting power supply to the traveling battery 8 of the own vehicle. 12 and the control device 12 of the in-vehicle device 1 of the electric vehicle (hereinafter referred to as a power supply candidate vehicle) on the side of receiving a power supply request.

  Hereinafter, for convenience, the vehicle-mounted device 1, the wireless communication device 11, and the control device 12 of the electric vehicle will be referred to as the vehicle-mounted device 1a, the wireless communication device 11a, and the control device 12a, and the vehicle-mounted device 1, the wireless communication device 11, and the control of the power supply candidate vehicle. The device 12 will be described as an in-vehicle device 1b, a wireless communication device 11b, and a control device 12b. The in-vehicle device 1a corresponds to the device for an electrically powered vehicle in the claims, and the in-vehicle device 1b corresponds to the device for a powered vehicle in the claims.

  For example, vehicle A in FIG. 1 is an electric shortage vehicle, and vehicle B, vehicle C, and vehicle D that are within the communication range of wireless communication device 11 of vehicle A (see the dashed circle in the figure) are power supply candidate vehicles. Suppose that Moreover, although mentioned later, the electric vehicle which received the electric power supply request | requirement of an electric shortage vehicle among electric power supply candidate vehicles is called an electric power feeding vehicle. In FIG. 1, it is assumed that the vehicle B is a power supply vehicle.

  Here, a process related to a power supply request (hereinafter referred to as a power supply request process) among processes related to power supply in the control device 12a of the in-vehicle device 1a will be described using the flowchart of FIG. The flow in FIG. 3 starts when, for example, a recommended route to the destination is searched by route search processing in the control device 12a, and starts when the ignition power source of the shortage car is turned on. To do.

  First, in step S1, a cruising range calculation process is performed, and the process proceeds to step S2. In the cruising range calculation process, the cruising range of the shortage is calculated based on the SOC monitored by the charge monitoring unit 7. During the description of the flow of FIG. 3 and FIG.

  For example, information on the average power consumption of the traveling battery 8 per fixed distance is previously stored in the nonvolatile memory of the control device 12a, and the remaining charge amount of the traveling battery 8 obtained from the SOC is calculated as the average power. What is necessary is just to set it as the structure which calculates the cruising range by dividing by consumption. Therefore, the control device 12a corresponds to the power receiving side remaining charge amount detecting means in the claims. Further, the remaining charge amount of the battery 8 for running out of the electric vehicle corresponds to the remaining charge amount on the power receiving side in the claims. About the average power consumption of the battery 8 for driving | running | working, the predetermined fixed value may be sufficient and the value updated for every day based on the past driving | running history may be sufficient.

  In step S2, it is determined whether or not the destination can be reached with the current remaining charge amount. If it is determined that the destination can be reached (YES in step S2), the flow returns to step S1 to repeat the flow. If it is determined that the destination cannot be reached (NO in step S2), the process proceeds to step S3.

  The determination as to whether or not the destination can be reached may be made as follows, for example. First, the current position of the own vehicle acquired from the position detector 2 of the own vehicle, the recommended route to the destination searched in the route search process (hereinafter, the recommended destination route), and the map data input device 3 of the own vehicle The distance (hereinafter referred to as the first remaining distance) of the section from the current position of the vehicle to the destination in the recommended destination route is calculated based on the link length data in the map data input from . Specifically, the first remaining distance may be calculated by adding up all the link lengths of the section from the current position of the host vehicle to the destination in the recommended destination route.

  When the first remaining distance is less than the cruising distance calculated by the cruising distance calculation process, it is determined that the destination can be reached, and the first remaining distance is longer than the cruising distance. May be configured to determine that the destination is not reachable.

  In step S3, it is determined whether or not the nearest chargeable facility can be reached with the current remaining charge amount. If it is determined that the nearest chargeable facility can be reached (YES in step S3), the flow returns to step S1 and the flow is repeated. If it is determined that the nearest rechargeable facility is not reachable (NO in step S3), the process proceeds to step S4. The chargeable facility mentioned here is a facility such as a charging stand that can charge the battery 8 for traveling of the electric vehicle.

  The determination as to whether or not the nearest chargeable facility can be reached may be made, for example, as follows. First, based on the current position of the host vehicle acquired from the position detector 2 and the map data input from the map data input unit 3, a chargeable facility existing at the shortest distance from the current position of the host vehicle is searched. The distance to the rechargeable facility that has been searched (hereinafter, the second remaining distance) is calculated.

  For example, the second remaining distance may be calculated by summing up all the link lengths of the section from the current position of the vehicle to the chargeable facility existing at the shortest distance. For rechargeable facilities, the background data described above includes coordinates on a rechargeable facility map. Therefore, the control device 12a corresponds to the power receiving side map data acquisition means in the claims.

  If the second remaining distance is less than the cruising distance calculated by the cruising distance calculation process, it is determined that the nearest chargeable facility can be reached, and the second remaining distance is longer than the cruising distance. In such a case, it may be determined that the nearest chargeable facility is not reachable. Therefore, the process of step S2 and step S3 is equivalent to the arrival determination means of a claim.

  In step S4, a power supply request confirmation process is performed, and the process proceeds to step S5. In the power supply request confirmation process, the display device 4 and the audio output device 5 of the own vehicle notify the vehicle battery 8 for own vehicle that power supply is necessary. Therefore, the process of step S4 corresponds to a power supply notification means in the claims. According to this, it is impossible to drive in a place where it is dangerous to park or stop because it predicts the lack of electricity of the own vehicle and notifies the user such as the driver of the own vehicle or a passenger other than the driver when there is still enough capacity to travel. You can avoid becoming.

  In step S5, it is determined whether or not there is a request to start power supply request. The presence / absence of a request for power supply request may be determined based on whether or not an operation input from the user to instruct the start of the power supply request is received via the operation switch group 6. As an example, when a signal indicating that a touch switch or a mechanical switch for instructing the start of a power supply request is operated is input from the operation switch group 6, the user instructs to start the power supply request. What is necessary is just to make it the structure which determines with having received the operation input. Therefore, the control device 12a corresponds to the operation accepting means in the claims.

  If it is determined that there is a request for starting the power supply request (YES in step S5), the process proceeds to step S6. If it is determined that there is no request for starting the power supply request (NO in step S5), the flow returns to step S4 to repeat the flow.

  If it is determined that neither the destination nor the nearest rechargeable facility is reachable, the power supply request confirmation process may be performed, and then the process may proceed to step S6 without performing step S5. . In other words, it may be configured to automatically determine whether or not it is necessary to start a power supply request. However, in order to avoid misjudgment due to destination setting mistakes, use of old map data, or the like, it is preferable not to automatically determine whether or not it is necessary to start a power supply request.

  In step S6, a power supply request transmission place determination process is performed, and the process proceeds to step S7. Here, the outline of the power supply request transmission place determination process will be described with reference to the flowchart of FIG. First, in step S61, a cruising range calculation process is performed in the same manner as in step S1, and the process proceeds to step S62.

  In step S62, a parking spot search process is performed, and the process proceeds to step S63. In the parking spot search process, based on the cruising distance calculated in step S61, the current position of the vehicle acquired from the position detector 2, and the map data input from the map data input unit 3, Search for a parking spot that is within the range where the vehicle can be reached by the amount of charge. Therefore, the process of step S62 is equivalent to the parking spot search means of a claim. The parking spot is a place where a power supply request can be transmitted and can be parked safely, for example, a parking lot of a facility such as a park or a convenience store.

  As an example, a parking spot that exists within a circle whose radius is the cruising range calculated in step S61 with the current position of the host vehicle as the center is extracted, and the current location of the host vehicle is extracted for each extracted parking spot. Calculate the total link length of the shortest route from the location to the parking spot. And it may be set as the structure which searches a parking spot by further narrowing down to the parking spot whose calculated total link length is below a cruising range.

  In step S63, a first required power supply amount calculation process is performed, and the process proceeds to step S64. In the first required power supply amount calculation process, for each of the parking spots searched in the parking spot search process in step S62, the destination and the nearest chargeable facility mentioned above from the current position of the vehicle through the parking spot. The amount of power supply required to reach the closer one of these (hereinafter referred to as the first required power supply amount) is calculated. Therefore, the process of step S63 corresponds to the first required power supply amount calculation means in the claims.

  As an example, the distance of the shortest route from the current position of the vehicle through the parking point to the destination or the nearest rechargeable facility is calculated as the total link length of this shortest route. Ask from. Subsequently, the amount of electric power required to complete the traveling of the shortest route is calculated from the average power consumption of the traveling battery 8 per certain distance and the distance of the shortest route. Then, the difference between the amount of electric power required to complete the traveling of the shortest route and the current remaining charge amount may be calculated as the first required power supply amount. The current remaining charge amount may be calculated based on the SOC monitored by the charge monitoring unit 7.

  In step S64, a parking spot list creation process is performed, and the process proceeds to step S65. In the parking spot list creation process, a list (hereinafter, a parking spot list) in which the parking spots searched in the parking spot search process are arranged in ascending order of the first required power supply amount calculated in the first required power supply amount calculation process is created. In addition, it is good also as a structure which creates the parking spot list | wrist which matched the value of the 1st required power supply amount for every parking spot, and creates the parking spot list which arranged the parking spot in order with few 1st required power supply amounts. It is good also as composition to do.

  In step S65, a parking spot list presentation process is performed, and the process proceeds to step S66. In the parking spot list presenting process, the parking spot list created in the parking spot list creating process is displayed on the display device 4 so that the parking spot list is presented to the user of the shortage car. Therefore, the process of step S65 corresponds to the parking spot presenting means in the claims. As an example of the display of the parking spot list, the names of the parking spots searched in the parking spot search process are displayed side by side so as to be positioned higher in the list as the first required power supply amount is smaller.

  According to this, by moving the host vehicle to the parking spot included in the parking spot list based on this parking spot list, the host vehicle can reach a safe place before it becomes impossible to run due to lack of electricity. Can be moved. In addition, by moving the own vehicle to a higher parking spot on the list based on the parking spot list, it is possible to suppress the amount of power supply necessary for the own vehicle and increase the number of vehicles that can supply power.

  In step S66, it is determined whether or not a parking spot is selected. Whether or not a parking spot is selected may be determined based on whether or not an operation input from the user for selecting any parking spot in the parking spot list is received via the operation switch group 6. . Therefore, the control device 12a corresponds to the parking spot selection means in the claims.

  If it is determined that a parking spot is selected (YES in step S66), the selected parking spot is determined as the power supply request transmission place, and the process proceeds to step S7. If it is determined that no parking spot is selected (NO in step S66), the flow in step S66 is repeated.

  Returning to FIG. 3, in step S7, a transmission place route search process is performed, and the process proceeds to step S8. In the transmission location route search process, the current position of the vehicle acquired from the position detector 2, the power supply request transmission location determined in the power supply request transmission location determination processing, and the map data input from the map data input device 3 are obtained. Based on the route search process described above, a recommended route from the current position of the vehicle to the place where the power supply request is transmitted is searched. Note that the place where the power supply request is transmitted corresponds to the selected parking spot in the claims.

  In step S8, a transmission place route guidance process is performed, and the process proceeds to step S9. In the dispatch location route guidance process, based on the current position of the host vehicle acquired sequentially from the position detector 2, the route guidance process described above supports the travel of the recommended route from the current position of the host vehicle to the power supply request dispatch location. Route guidance is performed.

  In step S9, it is determined whether or not the power supply request transmission place has been reached. Therefore, the process in step S9 corresponds to the arrival determination means in the claims. And when it determines with having arrived at the electric power feeding request transmission place (it is YES at step S9), it moves to step S10. If it is determined that the power supply request transmission place has not been reached (NO in step S9), the flow returns to step S8 to repeat the flow.

  For example, when the linear distance between the current position of the vehicle acquired from the position detector 2 and the power supply request transmission location is equal to or less than a predetermined distance (for example, ten or less meters), it is determined that the power supply request transmission location has been reached. What is necessary is just to be the structure to do. In addition, when the linear distance between the current position of the own vehicle and the power supply request transmission place is equal to or less than the predetermined distance, and the parking of the own vehicle is detected, it is determined that the power supply request transmission place has been reached. Also good. The detection of the parking of the host vehicle may be performed when it is detected that the shift position becomes the parking position based on a signal from a shift position sensor (not shown).

  In step S10, a second required power supply amount calculation process is performed, and the process proceeds to step S11. In the second required power supply amount calculation process, the power supply amount required to reach the closer of the above-mentioned destination and the above-mentioned nearest rechargeable facility from the current position of the own vehicle acquired from the position detector 2 (hereinafter referred to as the power supply amount) , Second required power supply amount) is calculated. Therefore, the process of step S10 corresponds to the second required power supply amount calculating means.

  As an example, the distance of the shortest route from the current position of the host vehicle to the destination or the nearest rechargeable facility is calculated from the total link length of the shortest route. Subsequently, the amount of electric power required to complete the traveling of the shortest route is calculated from the average power consumption of the traveling battery 8 per certain distance and the distance of the shortest route. Then, the difference between the amount of electric power required to complete the traveling of the shortest route and the current remaining charge amount may be calculated as the second required power supply amount. The current remaining charge amount may be calculated based on the SOC monitored by the charge monitoring unit 7.

  In step S11, a power supply request transmission process is performed, and the process proceeds to step S12. In the power supply request transmission process, information on the current position of the vehicle acquired from the position detector 2 and the second required power supply amount calculated in the second required power supply amount calculation process is sent to the battery 8 for traveling of the vehicle. A signal for requesting power supply (hereinafter referred to as a power supply request signal) is transmitted from the wireless communication device 11a by inter-vehicle communication. Therefore, the power supply request signal corresponds to the power supply request information in the claims, the control device 12a corresponds to the electric vehicle position acquisition means in the claims, and the wireless communication device 11a corresponds to the power receiving side communication means in the claims. Moreover, the process of step S11 is equivalent to the power supply request | requirement transmission means of a claim.

  That is, in the control device 1a, when an operation input from the user instructing the start of the power supply request is received, the control device 1a receives the power supply request signal triggered by the determination that the vehicle has arrived at the power supply request transmission place. Will be sent. In the present embodiment, the configuration in which the second required power supply amount is included in the power supply request signal is shown, but the present invention is not necessarily limited thereto. For example, the power supply request signal may not include the second required power supply amount.

  According to the above configuration, since the power supply request signal is transmitted from the wireless communication device 11a of the own vehicle through inter-vehicle communication, the driver of the unspecified number of other vehicles existing within the communication range of the wireless communication device 11a of the own vehicle. It is possible to request power supply by simultaneously notifying the current position of the vehicle. Therefore, it is possible to negotiate the power supply one by one by calling the contact information registered in the mobile phone, or to negotiate the power supply one by one to the driver of another vehicle existing within the range visible to the user. You can save time and effort.

  In addition, what is necessary is just to set it as the structure which adds identification information to the electric power feeding request signal so that the receiving vehicle can identify the own vehicle which is a transmission source. The identification information may be, for example, the vehicle ID of the own vehicle or the device ID of the wireless communication device 11a of the own vehicle. Hereinafter, the case where the device ID of the wireless communication device 11a of the own vehicle is used as the identification information that can identify the own vehicle will be described as an example.

  In step S12, it is determined whether or not a signal in response to the power supply request (hereinafter referred to as an acceptance signal) has been received. Whether or not the reception signal is received may be determined based on whether or not the reception signal received by the wireless communication device 11a is input to the control device 1a. And when it determines with having received the acceptance signal (it is YES at step S12), a flow is complete | finished. That is, when the acceptance signal is received, the transmission of the power supply request signal is stopped. If it is determined that the acceptance signal has not been received (NO in step S12), the process returns to step S11 and the flow is repeated.

  Next, processing related to reception of a power supply request (hereinafter referred to as power supply request reception processing) among processing related to power supply in the control device 12b of the in-vehicle device 1b will be described using the flowchart of FIG. . The flow in FIG. 5 starts when, for example, a recommended route to the destination is searched by the route search process in the control device 12b, and when the ignition power source of the power supply candidate vehicle is turned on. To do. During the description of the flow in FIG. 5, the power supply candidate vehicle is referred to as the own vehicle.

  First, in step S101, it is determined whether a power supply request signal has been received. Whether or not the power supply request signal is received may be determined based on whether or not the power supply request signal received by the wireless communication device 11b is input to the control device 12b. And when it determines with having received the electric power feeding request signal (it is YES at step S101), it moves to step S102. When it is determined that the power supply request signal has not been received (NO in step S101), the flow in step S101 is repeated.

  In step S102, a first power supply margin determination process is performed, and the process proceeds to step S103. In the first power supply margin determination process, it is determined whether or not the remaining charge amount of the traveling battery 8 of the own vehicle has a margin for supplying power to the traveling battery 8 of the electric vehicle. The first power supply margin determination process includes the current position of the shortage vehicle and the second required power supply amount included in the received power supply request information, the current position of the own vehicle acquired from the position detector 2 of the own vehicle, and the own vehicle This is performed based on the remaining charge amount of the traveling battery 8 obtained from the SOC monitored by the charge monitoring unit 7 and the map data inputted from the map data input device 3 of the own vehicle.

  Therefore, the control device 12b corresponds to the power supply side remaining charge amount detection means and the power supply vehicle position acquisition means. Further, the remaining charge amount of the running battery 8 of the power supply candidate vehicle corresponds to the remaining charge amount on the power supply side in the claims. Furthermore, the process of step S102 corresponds to the first securing determination means in the claims.

  As an example, the distance of the shortest path from the current position of the own vehicle to the current position of the shortage included in the power supply request signal is obtained from the total link length of the shortest path. In addition, the distance of the shortest route from the current position of the shortage to the destination of the own vehicle is obtained from the total link length of this shortest route. Subsequently, from the sum of the distances of these shortest routes and the average power consumption of the traveling battery 8 per a certain distance described above, the current position of the own vehicle is passed through the current position of the shortage vehicle. Calculate the amount of power required to arrive at the destination of your vehicle.

  Then, when the amount of electric power (hereinafter referred to as the first required total electric energy) that is the sum of the electric energy and the second required electric energy included in the electric power supply request signal is equal to or less than the remaining charge amount of the traveling battery 8 of the own vehicle. It may be determined that there is a margin for power supply, and if it is larger than the remaining charge amount, it is determined that there is no room for power supply. If the value obtained by subtracting the first required total power amount from the remaining charge amount of the traveling battery 8 of the own vehicle (hereinafter referred to as the first margin value) is equal to or greater than a predetermined positive value, there is a margin for power supply. It is good also as a structure which determines and it determines with there being no margin only to supply electric power, when a 1st margin value is less than predetermined | prescribed positive value.

  In step S103, when it is determined that there is a margin for power supply as a result of the first power supply margin determination process (YES in step S103), the process proceeds to step S104. Further, when it is determined that there is no room for power supply as a result of the first power supply margin determination process (NO in step S103), the flow ends.

  In step S104, a power supply request notification process is performed, and the process proceeds to step S105. In the power supply request notification process, the current position of the electric car is displayed on the display device 4 on the basis of the current position of the electric car that is included in the received electric power supply request signal. A notification indicating that a power supply request for requesting the power supply is made is sent to the user of the vehicle. Therefore, the process of step S104 corresponds to the power supply request notification means in the claims.

  In addition, what is necessary is just to set it as the structure superimposed on the electronic map displayed on the display apparatus 4 based on map data. In this case, the display may be performed using a mark or icon indicating that the current position of the electric car is present. In addition, text or an icon indicating that a power supply request has been made from an electric car is displayed on the display device 4, and a sound indicating that a power supply request has been made from an electric car is output from the audio output device 5. It is good also as a structure to make it do.

  In step S105, a request acceptance confirmation process is performed, and the process proceeds to step S106. In the request acceptance confirmation process, a notification for inquiring whether or not to respond to the power supply request from the shortage car is made from the display device 4 and the audio output device 5 of the own vehicle.

  According to the above configuration, the control device 12b automatically determines whether or not the power supply candidate vehicle has enough power to supply power to the shortage vehicle. It is not necessary to determine whether or not there is a margin of electric power for power supply by, for example, calculating the amount by the driver on the power supply candidate vehicle side. Therefore, it becomes possible for the driver on the power supply candidate vehicle side to quickly determine whether or not to accept the power supply request. In addition, this makes it possible to reduce the waiting time for power supply by the user of the electric shortage vehicle.

  In step S106, it is determined whether or not the power supply request is accepted. The presence / absence of acceptance of the power supply request may be determined based on, for example, whether or not an operation input from the user instructing acceptance of the power supply request is received within a predetermined time via the operation switch group 6.

  As an example, a signal indicating that a touch switch or a mechanical switch for instructing acceptance of a power supply request has been operated is input from the operation switch group 6 within a predetermined time after notification in the request acceptance confirmation process. In such a case, the power supply request may be accepted. Therefore, the control device 12b corresponds to the request receiving means in the claims.

  When a signal indicating that a switch for instructing acceptance of a power supply request has been operated is input from the operation switch group 6, it is determined that a power supply request has been accepted, while instructing that a power supply request has not been accepted. When a signal indicating that the switch is operated is input from the operation switch group 6, it may be determined that the power supply request is not accepted.

  If it is determined that the power supply request has been received (YES in step S106), the process proceeds to step S107. If it is determined that the power supply request has not been received (NO in step S106), the flow ends.

  In step S107, an acceptance signal transmission process is performed and the flow ends. In the reception signal transmission process, a signal indicating that the power supply request has been received (hereinafter referred to as a reception signal) is transmitted from the wireless communication device 11b by inter-vehicle communication. Therefore, the acceptance signal corresponds to the acceptance information in the claims, and the wireless communication device 11b corresponds to the power supply side communication means in the claims. Further, the processing in step S107 corresponds to the acceptance information transmitting means in the claims. A power supply candidate vehicle that transmits an acceptance signal in response to a power supply request is hereinafter referred to as a power supply vehicle.

  In addition, what is necessary is just to set it as the structure which adds identification information to the electric power feeding request signal so that the receiving vehicle can identify the own vehicle which is a transmission source. The identification information may be, for example, the vehicle ID of the own vehicle or the device ID of the wireless communication device 11b of the own vehicle. Hereinafter, the case where the device ID of the wireless communication device 11b of the own vehicle is used as the identification information that can identify the own vehicle will be described as an example.

  Further, the communication between the in-vehicle device 1a of the shortage vehicle and the in-vehicle device 1b of the power supply vehicle in response to the power supply request may be performed by inter-vehicle communication between the wireless communication device 11a and the wireless communication device 11b. Alternatively, for example, a configuration in which the communication is performed on a one-to-one basis via an in-vehicle communication module used for telematics communication such as DCM (data communication module) may be employed.

  In the present embodiment, the following description will be given by taking as an example a case where the communication is performed by inter-vehicle communication between the wireless communication device 11a and the wireless communication device 11b. In this case, the wireless communication device 11 that is the communication partner may be identified based on the above-described device ID, for example.

  The management server (not shown) collects the margin values calculated in the margin margin determination process for each candidate train vehicle that has received a feed request signal from the same shortage vehicle, and feeds power in order from the candidate trains with larger margin values. The management server may be configured to instruct the in-vehicle device 1b of each power supply candidate vehicle so that the request notification process is performed.

  In this case, whether or not each power supply candidate vehicle has received a power supply request signal from the same electric shortage vehicle is transmitted by transmitting the device ID included in the power supply request signal from the in-vehicle device 1 of the electric vehicle to the management server. The determination may be made based on the device ID. In addition, the communication between the management server and the in-vehicle device 1 may be configured to use a known road-to-vehicle communication or the like.

  Further, when the power supply request notification process is performed in order from the power supply candidate vehicle having the larger margin value, the power supply request notification process is performed in order from the power supply candidate vehicle having the larger margin value until a power supply candidate vehicle that accepts the power supply request appears. What is necessary is just to make it the structure which performs. Whether or not the power supply request is accepted may be determined by the management server by transmitting information on whether or not the power supply request is accepted from the in-vehicle device 1b of the power supply candidate vehicle.

  Subsequently, processing related to presentation of a power feeding location (hereinafter referred to as power feeding location presentation processing) among processing related to power feeding in the control device 12a of the in-vehicle device 1a will be described using the flowchart of FIG. . The flow in FIG. 6 starts when an acceptance signal is received from the power supply vehicle. In the description of the flow in FIG. 6, it is assumed that the electric car is called the own vehicle.

  First, in step S201, it is determined whether or not the current position of the host vehicle is designated as a power supply location. For example, a notification for inquiring whether or not to specify the current position of the host vehicle as a power supply location is made from the display device 4 or the audio output device 5, and an operation input for instructing the designation is made via the operation switch group 6. If it is accepted, it may be determined to be designated. In addition, when setting whether or not the current position of the host vehicle is designated as the power supply location has been performed in advance, it may be configured to determine whether or not to designate according to this setting.

  And when it determines with designating the present position of the own vehicle as an electric power feeding place (it is YES at step S201), it moves to step S204. If it is determined not to specify (NO in step S201), the process proceeds to step S202. In step S202, the cruising range calculation process is performed in the same manner as in step S1, and the process proceeds to step S203.

  In step S203, a power feeding place search process is performed, and the process proceeds to step S204. In the power feeding location search process, the current remaining distance is calculated based on the cruising range calculated in step S201, the current position of the vehicle acquired from the position detector 2, and the map data input from the map data input device 3. A parking spot that exists within a range that is estimated to be reachable by the amount of charge is searched for as a power feeding location. Therefore, the process of step S203 corresponds to the power supply location search means in the claims. The parking spot here is also the same as the parking spot described above.

  As an example, a parking spot existing within a circle whose radius is the cruising range calculated in step S201 centered on the current position of the own vehicle is extracted, and the current location of the own vehicle is extracted for each extracted parking spot. Calculate the total link length of the shortest route from the location to the parking spot. Then, the power supply location may be searched by further narrowing down to the parking spots where the calculated total link length is equal to or shorter than the cruising distance.

  In step S204, a third required power supply amount calculation process is performed, and the process proceeds to step S205. In the third required power supply amount calculation process, if it is determined that the current position of the own vehicle is designated as the power supply location, the current destination position of the own vehicle is closer to either the destination mentioned above or the nearest chargeable facility mentioned above. The amount of power supply required to reach the direction (hereinafter referred to as the third required power supply amount) is calculated.

  If it is determined that the current position of the host vehicle is not designated as the power feeding location, the power feeding location searched in the power feeding location search process in step S203 is passed through the power feeding location from the current position of the own vehicle. Then, a power supply amount (hereinafter referred to as a third required power supply amount) necessary to reach the closest destination of the aforementioned destination and the nearest chargeable facility of the current position of the vehicle is calculated. Therefore, the process of step S204 corresponds to the third required power supply amount calculating means. The rechargeable facility nearest to the current position of the vehicle may be searched in the same manner as described above.

  In step S205, power supply location information transmission processing is performed, and the flow ends. In the power supply location information transmission process, meeting location information including the power supply location and the third required power supply amount calculated in the third required power supply amount calculation process for the power supply location is transmitted from the wireless communication device 11a by inter-vehicle communication. .

  For example, if it is determined that the current position of the host vehicle is designated as the power supply location, information on the current position of the host vehicle and the third required power supply amount calculated by the third required power supply amount calculation process for the current position The meeting place information including is transmitted. If it is determined that the current position of the vehicle is not designated as a power supply location, the power supply location searched in the power supply location search process and the third required power supply amount calculation process calculated for each searched power supply location 3 The meeting place information including information on the required power supply amount is transmitted. Therefore, the meeting place information corresponds to the power supply candidate information in the claims, and the processing in step S205 corresponds to the power supply candidate transmission means in the claims.

  Subsequently, processing related to determination of a power supply location (hereinafter referred to as power supply location determination processing) among processing related to power supply in the control device 12b of the in-vehicle device 1b will be described using the flowchart of FIG. . The flow in FIG. 7 is started when the meeting place information is received from the electric car. In the description of the flow of FIG. 7, the power supply vehicle is referred to as the own vehicle.

  First, in step S301, it is determined whether or not the power feeding place included in the received meeting place information is the current position of the shortage car. And when it determines with a power feeding place being the present position of an electric shortage vehicle (it is YES at step S301), it moves to step S305. On the other hand, if it is determined that the power feeding location is not the current position of the shortage car (NO in step S301), the process proceeds to step S302.

  Whether the power supply location is the current position of the electric vehicle is determined by the current location of the electric vehicle when the current location of the electric vehicle is included in the waiting location information as the power supply location in the power supply location information transmission process described above. What is necessary is just to set it as the structure which adds the classification information which shows that it exists, and determines according to whether this classification information is added to the meeting place information. In addition, in the above-described power feeding location information transmission process, the current location of the missing car in addition to the feeding location is included in the waiting location information, and the feeding location and the current location of the missing car are included in the waiting location information. It is good also as a structure which determines with the electric power feeding place being the present position of an electric shortage vehicle.

  In step S302, a second power supply margin determination process is performed, and the process proceeds to step S303. In the second power supply margin determination process, is the remaining charge amount of the traveling battery 8 of the host vehicle sufficient to supply power to the traveling battery 8 of the unoccupied vehicle at each power supply location included in the meeting place information? Determine whether or not. The second power supply margin determination process includes each power supply location and the third required power supply amount for each power supply location included in the received meeting location information, the current position of the own vehicle acquired from the position detector 2 of the own vehicle, and This is performed based on the remaining charge amount of the traveling battery 8 obtained from the SOC monitored by the charge monitoring unit 7 of the own vehicle and the map data input from the map data input device 3 of the own vehicle. Therefore, the process of step S302 corresponds to the second securing determination means in the claims.

  As an example, the distance of the shortest route from the current position of the vehicle to the power supply location included in the meeting place information is obtained from the total link length of the shortest route. Further, the distance of the shortest route from the power feeding place to the destination of the own vehicle is obtained from the total link length of this shortest route. Subsequently, from the distance obtained by adding the distances of these shortest paths and the average power consumption of the traveling battery 8 per a certain distance as described above, the current position of the own vehicle is passed through the power feeding location from the current position of the own vehicle. Calculate the amount of power required to arrive at the destination.

  Then, the total amount of power (hereinafter referred to as the second required total power amount) of the power amount and the third required power amount for the power supply location included in the meeting place information is the remaining amount of the traveling battery 8 of the vehicle. It may be determined that when there is a charge amount or less, it is determined that there is a margin for supplying power, and when it is greater than the remaining charge amount, it is determined that there is no margin for supplying power. In addition, when the value (second margin value) obtained by subtracting the second required total power amount from the remaining charge amount of the traveling battery 8 of the own vehicle is equal to or greater than a predetermined positive value, it is determined that there is a margin for power supply. A configuration may be adopted in which it is determined that there is no room for power supply in the remaining area where the second margin value is less than a predetermined positive value. In the second power supply margin determination process, the above-described determination is performed for each power supply location included in the meeting place information.

  In step S303, an exclusion process is performed, and the process proceeds to step S304. In the exclusion process, as a result of the second power supply margin determination process, a power supply location that has been determined not to have sufficient room for power supply is excluded from power supply location candidates.

  In step S304, a power supply location list creation process is performed, and the process proceeds to step S305. In the power feeding location list creation process, a list (hereinafter referred to as a power feeding location list) in which the power feeding locations included in the meeting place information that are not excluded in the exclusion process are arranged in order of proximity to the destination of the vehicle is created. To do. In addition, it is good also as a structure which produces | generates the electric power feeding place list which matched the value of the 3rd required electric power supply amount for every electric power feeding place, and produces the electric power feeding place list which only arranged the electric power feeding place in the order close to the destination of the own vehicle. It is good also as composition to do. The distance between the power supply location and the destination of the host vehicle may be configured to use the distance of the shortest route from the power supply location to the destination of the host vehicle obtained in the second power supply margin determination process. The power supply location list corresponds to the power supply location candidate list in the claims.

  In step S305, a power feeding location presentation process is performed, and the process proceeds to step S306. In the power feeding location presentation process, when it is determined that the power feeding location is not the current position of the electric shortage vehicle, the power feeding location list created by the power feeding location list creation processing is displayed on the display device 4 to thereby display the power feeding location list. Is presented to the user of the powered vehicle. Therefore, the process of step S305 corresponds to the power supply location candidate presenting means in the claims.

  As an example of the display of the power supply location list, among the power supply locations included in the meeting location information, the name of the power supply location that is not excluded by the exclusion process is positioned higher in the list as the vehicle is closer to the destination. Are displayed side by side.

  According to this, since the user of the power supply vehicle can determine the power supply location close to the destination of the own vehicle based on the power supply location list, the user can move the vehicle to a higher power supply location on the list. In addition, it is possible to suppress the detour due to the supply of power to the shortage car.

  As an example of the display of the power supply location list, among the power supply locations included in the meeting location information, the power supply location that is not excluded by the exclusion process is closer to the higher position of the list as the vehicle is closer to the current location. It is good also as a structure displayed side by side like this. In this case, in the power feeding location list creation process, a configuration is created in which power feeding locations that are not excluded in the exclusion processing among power feeding locations included in the meeting place information are arranged in order from the current position of the vehicle. And it is sufficient.

  Further, in the power feeding location presentation process, when it is determined that the power feeding location is the current position of the shortage vehicle, the current position of the shortage vehicle is displayed on the display device 4 as the power feeding location. As an example of the display here, the name of a place (facility) corresponding to the current position of the electric car is displayed.

  In step S306, it is determined whether or not a power supply location is selected. The presence / absence of selection of the power supply location may be determined based on whether or not an operation input from the user for selecting one of the power supply locations in the power supply location list is received via the operation switch group 6. . Therefore, the control device 12b corresponds to the power supply location selection means in the claims. In the case where the current position of the power failure car is displayed as the power supply location, the determination may be made based on whether or not an operation input from the user to select this power supply location is received.

  If it is determined that a power supply location has been selected (YES in step S306), the selected power supply location is determined as a power supply waiting location, and the process proceeds to step S307. If it is determined that no power supply location is selected (NO in step S306), the flow in step S306 is repeated.

  In step S307, a determination location information transmission process is performed, and the flow ends. In the determined location information transmission process, the determined location information including information on the current position of the vehicle acquired from the position detector 2 and the power supply location determined as a power supply meeting location (hereinafter, determined power supply location) is wirelessly communicated. It is transmitted from the machine 11b by inter-vehicle communication. Therefore, the process of step S307 corresponds to the selective power supply location transmitting means in the claims.

  In addition, in the flow of FIG. 6, when the current position of the shortage car is set as the power feeding place, a configuration is shown in which meeting place information including information on the current position of the own vehicle and the third required power supply amount is transmitted. However, it is good also as a structure which transmits the meeting place information containing the information of 2nd required electric power supply amount instead of 3rd required electric power supply amount.

  Further, in the flow of FIG. 6, a configuration has been shown in which both the current position of the electric shortage vehicle and a place other than the current position can be designated as the power feeding place, but the present invention is not necessarily limited thereto. For example, it is good also as a structure which uses only the present position of an electric car as a feeding place. In this case, when the vehicle-mounted device 1a of the electric vehicle lacks the acceptance signal transmitted from the vehicle-mounted device 1b, the current position of the electric vehicle is determined as the power supply location, and the vehicle-mounted device 1b of the electric vehicle is When the acceptance signal is transmitted, the current position of the shortage car included in the power supply request signal may be determined as the power supply location.

  Furthermore, in the above-described embodiment, when a power supply request is made in the flow of FIG. 1, a parking spot that is a place where the car can be safely parked is searched, and a power feeding request signal is transmitted after guiding an electric shortage to the parking spot. Although the structure to make was shown, it is not necessarily restricted to this. For example, when an operation input is received from the user instructing the start of a power supply request during parking of an electric shortage vehicle, the process proceeds to step S10 without performing the processes in steps S6 to S9 described above. It is good.

  Next, with reference to the flowchart of FIG. 8, a description will be given of a process related to guidance to a power feeding place (hereinafter referred to as a power feeding place guidance process) among processes related to power feeding in the control device 12 a of the in-vehicle device 1 a. Do. The flow in FIG. 8 is started when the determination place information from the power supply vehicle is received. In addition, the power supply location guidance process in the control device 12a is performed when a location other than the current position of the shortage car is determined as the power supply location, and is not performed when the current location of the shortage vehicle is determined as the power supply location. Shall. During the description of the flow of FIG.

  First, in step S401, a power feeding location route search process is performed, and the process proceeds to step S402. In the power feeding location route search process, based on the current position of the vehicle acquired from the position detector 2, the determined power feeding location included in the received determined location information, and the map data input from the map data input device 3. The recommended route from the current position of the host vehicle to the determined power supply location is searched by the route search process described above. Therefore, the process of step S401 corresponds to the power receiving side route searching means in the claims.

  In step S402, power feeding location route guidance processing is performed, and the process proceeds to step S403. In the power feeding location route guidance process, the travel of the recommended route from the current position of the own vehicle to the determined power feeding location is supported by the above-described route guidance processing based on the current position of the own vehicle sequentially acquired from the position detector 2. Provide route guidance. Therefore, the process of step S402 corresponds to the power receiving side guiding means in the claims.

  In step S403, the current vehicle status information transmission process is performed, and the process proceeds to step S404. In the own vehicle current state information transmission process, the current position of the own vehicle obtained from the position detector 2, the remaining charge amount of the running battery 8 of the own vehicle obtained from the SOC monitored by the charge monitoring unit 7, and the determined power supply of the powered vehicle The vehicle current state information including the estimated arrival time at the place is transmitted from the wireless communication device 11a by inter-vehicle communication. Therefore, the processing in step S403 corresponds to the power receiving side current state transmission unit in the claims.

  The estimated arrival time at the determined power supply location is calculated based on the average speed of the vehicle, the distance from the current position to the determined power supply location, and the current time, or travels through each link from the current position to the determined power supply location. What is necessary is just to set it as the structure calculated based on the link travel time in this case, and the present time.

  In step S404, other vehicle current state information reception processing is performed, and the process proceeds to step S405. In the other vehicle current state information reception process, the other vehicle current state information transmitted from the powered vehicle is acquired via the wireless communication device 11a. The other vehicle current status information includes the current position of the power supply vehicle acquired from the position detector 2 of the power supply vehicle and the battery for driving the power supply vehicle obtained from the SOC monitored by the charge monitoring unit 7 of the power supply vehicle. It is assumed that the remaining charge amount of 8 and the estimated arrival time at the determined power supply location are included.

  In step S405, other vehicle current state information presentation processing is performed, and the process proceeds to step S406. In the other vehicle current status information presenting process, the current position of the powered vehicle, the remaining charge amount of the running battery 8 of the powered vehicle, and the estimated arrival time at the determined feeding location of the powered vehicle are displayed on the display device 4. By displaying the information, the current state of the power supply vehicle is presented to the user of the own vehicle. Therefore, the processing in step S405 corresponds to the power supply vehicle current state presenting means in the claims.

  In addition, what is necessary is just to set it as the structure superimposed on the electronic map displayed on the display apparatus 4 based on map data. In this configuration, the current positions of the electric shortage vehicle and the power supply vehicle are displayed on the electronic map. In addition, it is good also as a structure displayed using the mark and icon which show that it is the present position of a feeding vehicle. Further, the remaining charge amount of the running battery 8 of the power supply vehicle and the estimated arrival time at the determined power supply location of the power supply vehicle are displayed in a pop-up on the display location of the current position of the power supply vehicle, or other than the display location of the current position of the power supply vehicle It is good also as a structure displayed on this area | region.

  In step S406, it is determined whether or not both vehicles (both own vehicle and power supply vehicle) have arrived at the determined power supply location. And when it determines with both vehicles having arrived (it is YES at step S406), a flow is complete | finished. If it is determined that neither vehicle has arrived (NO in step S406), the flow returns to step S402 and the flow is repeated.

  For example, whether or not the own vehicle has arrived at the determined power supply location may be configured in the same manner as in the determination of whether or not the vehicle has arrived at the power supply request transmission location in step S9 described above. In addition, as to whether or not the power supply vehicle has arrived at the determined power supply location, for example, the linear distance between the current position of the power supply vehicle and the determined power supply location included in the other vehicle current status information is a predetermined distance or less (for example, a few dozen meters or less) ), It may be configured to determine that it has arrived at the determined power supply location.

  According to the above configuration, it becomes possible for the user of the shortage car to sequentially check the current position of the power supply vehicle, so that the power supply vehicle stops moving to the determined power supply location on the way or the determined power supply location is crowded. Therefore, it is possible to detect that a problem has occurred with respect to the merge of the power supply vehicle to the determined power supply location such as moving to another nearby location. Accordingly, it is possible to detect that a problem has occurred regarding the merge of the power supply vehicle to the determined power supply location and take appropriate measures.

  In addition, since the user of the shortage vehicle can sequentially check the remaining charge amount of the battery 8 for traveling of the power supply vehicle, if the power supply vehicle cannot join the determined power supply location due to power shortage, It becomes possible to detect and take appropriate action. In addition, it is possible for the user of the shortage car to check the expected arrival time at the determined power supply location of the power supply car one after another, so that the approximate wait time until power supply can be known, and the wait time is unknown Anxiety caused by can be resolved.

  In addition, although the electric power feeding place induction | guidance | derivation process in the control apparatus 12a of the vehicle-mounted apparatus 1a of an electric shortage vehicle was demonstrated using the flow of FIG. 8, the electric power feeding place induction | guidance | derivation in the control apparatus 12a of the vehicle-mounted apparatus 1b of an electric power feeding vehicle was performed. The processing is also the same as that shown in the flow of FIG. Specifically, it is the same except that the processing of the in-vehicle device 1a of the electric shortage vehicle and the in-vehicle device 1b of the power supply vehicle is switched and that the flow is started when the determined place information is transmitted. The power feeding location guidance process in the control device 12a of the in-vehicle device 1b of the power feeding vehicle is also performed when the current position of the power loss vehicle is determined as the power feeding location.

  Therefore, the control device 12b corresponds to a power supply side map data acquisition unit, a power supply side route search unit, a power supply side guide unit, a power supply side current state transmission unit, and an electric vehicle current state presentation unit.
