Description

  Embodiments described herein relate generally to a charging facility reservation management device, a charging facility reservation terminal, and an electric vehicle.

  Since an electric vehicle needs to be charged in a battery, the continuous travel distance is short, and charging takes a long time. For example, it takes about 30 minutes to charge to about 80% even when a quick charger is used. In addition, charging facilities for electric vehicles are not widely used because of the high cost of installation, and there are currently few charging facilities.

  In this way, since a small number of charging facilities tend to be occupied for a long time by the electric vehicle being charged, even if the electric vehicle needs to be charged, it cannot be immediately charged, and the charging facility Sometimes you have to wait until it is free.

  Therefore, in order to efficiently use a small number of charging facilities, a system for making a reservation for using charging facilities in advance has been proposed.

This is realized by the CPU of the control unit 42 of the facility X, Y operating according to the control program.

  FIG. 7 is a flowchart showing a procedure for reserving an electric vehicle charging facility.

  First, the control unit 32 of the vehicle-mounted device 3A mounted on the vehicle A uses the GPS of the navigation system 36 as information indicating the vehicle status of the vehicle A, and information on the latitude 262 and longitude 263 that are the current position of the vehicle A. As well as information on the travelable distance 265 from the remaining battery level (step S1).

  Next, the control unit 32 of the vehicle-mounted device 3A stores the latitude 231 and longitude 232 of the charging facility as the location information of the charging facility within the travelable range based on the acquired current position of the vehicle A and the travelable distance. 33, the position of the charging facility is acquired (step S2).

  In this embodiment, the location information of what is within the range that can be traveled as the charging facility is read in step S2, but the present invention is not limited to this, and the charging facility existing in the prefecture where the vehicle is currently located, Information on charging facilities in the range of may be read. The vehicle-mounted device 3A may be capable of freely setting the range of the charging facility where the location information is read.

  Next, the control unit 32 of the vehicle-mounted device 3A includes information on the operating status of the charging facility whose location information has been read in step S2 (charging facility operating status information, see FIG. 4) and information on the reservation status (charging facility reservation status information). , (See FIG. 5) is transmitted to the reservation management apparatus 2 (step S3).

  When the control unit 22 of the reservation management device 2 receives the transmission request for the operation status information and the reservation status information from the vehicle-mounted device 3A (step S201), the control unit 22 of the charge facility operation status storage unit 24 sends a request for the requested charging facility. The operation status information is read (step S202), and the reservation status information of the requested charging facility is read from the charge reservation storage unit 25 (step S203).

  FIG. 8 is a diagram illustrating an example of a data table stored in the charging facility operation status storage unit 24 of the reservation management device 2. In the data table shown in FIG. 8, as the operating status of the charging facility, the identification ID of the vehicle-mounted device mounted on each reserved vehicle, the latitude and longitude indicating the location of the charging facility, and the charging start time 244 of each vehicle. And the scheduled charging end time 245 are stored in association with each other.

  FIG. 9 is a data table stored in the charge reservation storage unit 25 of the reservation management device 2. In the data table shown in FIG. 9, as the charging facility reservation status, the identification ID of the vehicle-mounted device mounted in each vehicle that has made a reservation, the latitude and longitude indicating the location of the charging facility, and the scheduled charging start time for each vehicle 254 and scheduled charging end time 255 are stored.

  The control unit 22 of the reservation management device 2 extracts charging facilities and time zones that can be reserved using these data tables. Specifically, the control unit 22 of the reservation management device 2 uses the data table stored in the charging facility operation status storage unit 24 to indicate the charging facility and time zone that are vacant at the current time acquired by a timing unit (not shown). At the same time, the charging facility and time zone that are available in the future are extracted from the data table stored in the charging reservation storage unit 25.

  As a specific example, assuming that the current time is 9:13, the charging facility operating state of FIG. 8 does not include charging facilities at latitude 488135 and longitude 182135, so that the charging is performed at 9:13, which is the current time. It can be seen that the facility is not being charged. Further, in the charging facility reservation situation of FIG. 9, it can be seen that the charging reservation scheduled start time at the charging facility at latitude 488135 and longitude 182135 is 10:00, and no reservation is made until 9:59. Therefore, it can be seen that the charging facility at latitude 488135 and longitude 182135 is a facility that can be reserved between 9:13 and 9:59 (hereinafter referred to as “vacant facility”).

  Similarly, assuming that the current time is 9:13, in the charging facility operating state of FIG. 8, charging start time of charging facilities at latitude 491735 and longitude 185735 is 8:55, and scheduled end time is 9:15. Therefore, it can be seen that the electric vehicle is currently being charged at the charging facility, and that the charging facility cannot be used until 9:15, which is the scheduled end time of the charging. Further, in the charging facility reservation situation of FIG. 9, the start time of the next charging reservation of the charging facility at latitude 491735 and longitude 185735 is 10:00. Therefore, in the charging facility, it can be understood that the charging facility is an empty facility from 9:15 after the end of the currently performed charging to 9:59 before the start of the next charging reservation.

  Returning to the flowchart of FIG. 7, the control unit 22 of the reservation management apparatus 2 extracts a charging facility and a time zone that can be reserved from the read operation status information and reservation status information of the charging facility (step S <b> 204). Information on possible charging facilities and time zones is transmitted to the vehicle-mounted device 3A (step S205).

  Next, when the control unit 32 of the vehicle-mounted device 3A receives information on the rechargeable charging facility and time zone transmitted from the reservation management device 2 (step S4), the received reservable charging facility and time zone information is received. Is displayed on the display 35 (step S5).

  Next, when the control unit 32 of the vehicle-mounted device 3A receives selection of a specific charging facility and time zone selected by the driver based on the information displayed on the display 35 (step S6), the control unit 32 is selected as the received charging destination. Information indicating the specific charging facility and the time zone is transmitted to the reservation management device 2 (step S7).

  When the control unit 22 of the reservation management apparatus 2 receives the information transmitted from the vehicle-mounted device 3A and indicating the charging facility selected as the charging destination of the vehicle A and the time zone for charging (step S206), the received information It memorize | stores in the charge reservation memory | storage part 25 (step S207). In this way, the reservation of the charging facility is completed.

  By the way, the vehicle may not reach the charging facility at the reserved time. The causes include, for example, that the electricity stored in the battery is insufficient and the reserved charging facility cannot be reached, or that the battery has sufficient electricity but the arrival is delayed due to traffic congestion. Therefore, in the first embodiment, assuming that there are two vehicles placed in such a situation (vehicle A and vehicle B), by exchanging reservations, the charging facilities newly reserved by the respective vehicles are changed. An example of becoming reachable will be described (see FIG. 1).

  FIG. 10 is a flowchart showing a procedure for changing a charging facility reservation. The driver of the vehicle A who has difficulty reaching the reserved charging facility at the reserved time operates the input unit 34 of the vehicle-mounted device 3A and starts the reservation changing operation.

  First, the controller 32 of the vehicle-mounted device 3A determines whether or not it is difficult to reach the charging facility, the position information of the vehicle A by GPS, the reserved charging facility stored in the memory 33, and the scheduled start time of charging. The determination is made based on the average speed 264 of the vehicle A, the remaining battery level, and the like.

  Specifically, when the vehicle 32 travels at the average speed of the vehicle A from the current position of the vehicle A to the reserved charging facility, the control unit 32 of the vehicle-mounted device 3A reaches the charging facility by the scheduled start time of charging. If it is not possible, or even if it can be reached, if the interval between the expected arrival time and the scheduled start time falls below a predetermined time, it is determined that it is difficult to reach the charging facility. In addition, the control unit 32 of the vehicle-mounted device 3A, when traveling the distance from the current position of the vehicle A to the reserved charging facility, cannot travel with the remaining battery remaining amount, or even if it can travel, the battery remaining amount is predetermined. If the value is lower than the value, it is determined that it is difficult to reach the charging facility.

  Then, when it is determined that it is difficult to reach the reserved charging facility, the control unit 32 of the vehicle-mounted device 3A displays on the display 35 that it is difficult to reach the charging facility. Then, the driver who sees the display can change the reservation to another reachable charging facility. The reservation is changed by the driver operating the input unit 34 or the display 35.

  When the reservation change instruction from the driver is given by the operation of the input unit 34, the control unit 32 of the vehicle-mounted device 3A first uses the navigation system 36 as the vehicle status information of the vehicle A at the current position of the vehicle A. Information on a certain latitude and longitude is acquired, and information on a travelable distance is acquired from the remaining battery level (step S11).

  Next, the control unit 32 of the vehicle-mounted device 3A obtains the latitude and longitude of the charging facility from the memory 33 as the location information of the charging facility within the travelable range based on the acquired current position and travelable distance of the vehicle A. Read (step S12).

  Next, the control unit 32 of the vehicle-mounted device 3A includes information indicating an empty facility included in the travelable charging facility in which the location information is read in step S2, and replacement candidates associated with the travelable charging facility. A transmission request (exchange candidate request) with charging reservation information (including at least one of the location of the charging facility and the scheduled charging time) indicating an unreachable reservation of the other electric vehicle is transmitted to the reservation management device 2 ( Step S13: First exchange candidate request transmission means).

  Here, the unreachable reservation means the charging facility reserved at the scheduled charging start time, which is derived by the control unit 22 of the reservation management device 2 based on the information on the reservation status of the charging facility and the vehicle status of each vehicle shown in FIG. It is a reservation that is difficult to reach. Information included in the unreachable reservation includes, for example, the latitude and longitude of the reservation destination of the vehicle that cannot reach the reserved charging facility.

  When the control unit 22 of the reservation management apparatus 2 receives a transmission request (replacement candidate request) of information on unreachable reservations of the vacant facilities that can travel and other electric vehicles associated with the charging facilities that can travel ( Step S211: First receiving means), from among charging facilities within a travelable distance, an empty facility at the current time is extracted from a data table stored in the charging facility operating status storage unit 24 as a reservable free facility At the same time, a free facility that will be generated in the future is extracted from the data table stored in the charge reservation storage unit 25 (step S212).

  Next, the control unit 22 of the reservation management device 2 determines that the electric vehicle that transmitted the replacement candidate request out of the charging reservation information of another electric vehicle different from the electric vehicle that transmitted the replacement candidate request is the vehicle status of the electric vehicle. Charging reservation information that can be used from the driving status indicated by the information and cannot be used by the other electric vehicle in the driving status indicated by the vehicle status information of the other electric vehicle (the location of the charging facility and the estimated charging time Are extracted) (step S213: first extracting means). The unreachable reservation is derived as follows by the control unit 22 of the reservation management apparatus 2.

  First, the control unit 22 of the reservation management device 2 includes the current position (latitude 262, longitude 263) of each vehicle stored in the vehicle status storage unit 26 (see FIGS. 2 and 6) and the charging facility location storage unit 23. Based on the position (latitude 231 and longitude 232) of the reserved charging facility stored in (refer to FIGS. 2 and 3), the distance between each vehicle and the charging facility of the reservation destination by each vehicle is calculated.

  Then, the control unit 22 of the reservation management device 2 reaches the charging facility based on the calculated distance and the average speed 264 or the travelable distance 265 of each vehicle stored in the vehicle status storage unit 26. Determine the possibility.

  The first method calculates the estimated arrival time of each vehicle to the charging facility reserved based on the calculated distance and the travelable distance 265 of each vehicle stored in the vehicle status storage unit 26. Then, it is determined whether or not the vehicle can be used when the vehicle reaches the reservation charging facility at the estimated arrival time. Specifically, even if the control unit 22 of the reservation management device 2 can travel the distance, if the interval between the expected arrival time and the scheduled start time for the facility falls below a predetermined time, It is difficult to reach the charging facility and it is determined that it cannot be used. On the other hand, the control unit 22 of the reservation management device 2 travels the distance, and the charging facility can be used when the interval between the estimated arrival time and the scheduled start time is within a predetermined time. Is determined.

  Based on the calculated distance and the average speed 264 of each vehicle stored in the vehicle status storage unit 26, the second method calculates the estimated arrival time of each vehicle to the reservation charging facility, It is determined whether or not the vehicle can be used when the vehicle reaches the reservation charging facility at the estimated arrival time. Specifically, when the vehicle travels at an average speed 264, the control unit 22 of the reservation management device 2 is difficult to reach the charging facility if the vehicle cannot travel the distance by the scheduled charging start time. Judged as unavailable. On the other hand, when the vehicle travels at the average speed 264, the control unit 22 of the reservation management device 2 determines that the charging facility can be used if the vehicle can travel the distance by the scheduled charging start time.

Further, when the distance is longer than the travelable distance 265, or when the distance is shorter than the travelable distance 265, the control unit 22 of the reservation management device 2 It is determined that it is difficult to reach the charging facility.

  And the control part 22 of the reservation management apparatus 2 extracts the reservation which has become difficult to reach the charging facility reserved at the charging start scheduled time determined as described above as the unreachable reservation.

  That is, in step S213, among the charging reservation information of other electric vehicles different from the vehicle A on which the vehicle-mounted device 3A that transmitted the replacement candidate request is mounted, the vehicle A that transmitted the replacement candidate request is the vehicle of the vehicle A. At least one of the location of the charging facility and the scheduled charging time that can be used from the driving status indicated by the status information and cannot be used by the other electric vehicle in the driving status indicated by the vehicle status information of the other electric vehicle. It functions as an extracting means for extracting charging reservation information including one.

  Returning to the flowchart of FIG. 10, the control unit 22 of the reservation management device 2 includes information indicating an empty facility within the travelable distance and other electric vehicles associated with the charging facility within the travelable distance. Charge reservation information indicating an unreachable reservation is transmitted to the vehicle-mounted device 3A (step S214: first transmission means).

  The control unit 32 of the in-vehicle device 3A becomes an exchange candidate associated with the charging facility located within the travelable distance from the reservation management device 2 and the information indicating the vacant facility available for travel within the travelable distance. When receiving the charge reservation information indicating the unreachable reservation of another electric vehicle (step S14: first charge reservation information receiving means), the received information indicating the reservable vacant facilities and the unreachable reservation as a replacement candidate are received. The charging reservation information shown is displayed on the display 35 (step S15). Here, the control unit 32 of the vehicle-mounted device 3A determines the position (latitude 252 and longitude 253) of the charging facility included in the information indicating the reservation status of other electric vehicles as information indicating the empty facility in step S14. Obtained from the information being received. And the control part 32 of 3A of onboard equipment displays the position of the said facility as information which shows an empty facility.

  Next, when the driver operates the input unit 34 and the display 35 to select a desired item from the list of actual reservation information displayed on the display 35, the control unit 32 of the vehicle-mounted device 3A Information indicating the contents of the operation is received, and reservation information is selected (step S16).

  Next, the control unit 32 of the vehicle-mounted device 3A determines whether or not the selection by the driver accepted in step S16 has been made for the charge reservation information indicating the unreachable reservation (step S17).

  When the selection by the driver is performed for the charge reservation information indicating the unreachable reservation (step S17: Yes), the control unit 32 of the on-vehicle device 3A specifies the charge reservation information to be exchanged indicating the selected unreachable reservation. The designation information is transmitted to the reservation management apparatus 2 (step S18: first designation information transmission means).

  On the other hand, if the selection by the driver is not made for the unreachable reservation in step S17, that is, if it is made for the vacant facility (step S17: No), the control unit 32 of the vehicle-mounted device 3A selects the selected vacant facility. Is stored in the memory 33 as a reservation destination (step S19). Then, the control unit 32 of the vehicle-mounted device 3A transmits information on the charging facility that is the selected vacant facility and the time zone to the reservation management device 2 (step S20). Information on the charging facility and time zone selected by the driver is stored in the charging reservation storage unit 25 of the reservation management device 2.

  FIG. 11 is a flowchart showing processing by the reservation management apparatus 2 that has received the designation information to be exchanged.

  First, when the control unit 22 of the reservation management device 2 receives the designation information to be exchanged from the vehicle A (step S31: second receiving means), the reservation of the vehicle B that is the exchange request destination from the charge reservation storage unit 25. The situation is searched (step S32).

  Next, the control unit 22 of the reservation management apparatus 2 determines whether or not the vehicle B is still holding a reservation for which the driver of the vehicle A requests replacement based on the search result of the reservation status of the vehicle B. (Step S33).

  When the reservation requesting the exchange is still for the vehicle B, that is, when the reservation is associated with 10B that is the identification ID of the vehicle B (step S33: Yes), the control unit 22 of the reservation management apparatus 2 determines the exchange result. Until reservation information of the vehicle B stored in the charging reservation storage unit 25 cannot be changed (step S34).

  Next, the control unit 22 of the reservation management device 2 transmits a replacement request to the vehicle-mounted device 3B of the vehicle B that is the replacement request destination having the identification information included in the charging reservation information designated by the designation information (step) S35: Second transmission means). As this exchange request, the identification ID of the vehicle B, the location (latitude, longitude) of the charging facility where the vehicle B has made a reservation, the scheduled charging time (the scheduled charging start time and the scheduled charging end time), and the transmission source vehicle A Includes the location (latitude, longitude) of the charging facility where the charging is reserved and the scheduled charging time (the scheduled charging start time and the scheduled charging end time).

  On the other hand, when the reservation requesting the exchange is not already for the vehicle B, that is, when the reservation is not associated with the vehicle B ID 10B (step S33: No), the control unit 22 of the reservation management device 2 An error message for selecting another reservation is transmitted to the vehicle-mounted device 3A (step S36).

  FIG. 12 is a flowchart illustrating processing by the vehicle-mounted device 3B of the vehicle B that has received the replacement request.

  First, the control unit 32 of the vehicle-mounted device 3B includes the location included in the charging reservation information of the vehicle A that is the request source (the transmission source of the specified information) transmitted from the reservation management device 2 and the charging reservation information of the vehicle B. When an exchange request with the scheduled charging time is received (step S41: first exchange request receiving means), the contents of the exchange request are displayed on the display unit 35 (step S42).

  Next, the control unit 32 of the vehicle-mounted device 3B determines whether or not the response request displayed on the display unit 35 has been selected by the driver of the vehicle B (step S43). This selection is performed by the driver operating the input unit 34 and the display unit 35.

  When there is a response selection (step S43: Yes), the control unit 32 of the vehicle-mounted device 3B determines whether the selection is a response to a replacement request (step S44).

  When selection according to the exchange request has been made (step S44: Yes), the control unit 32 of the vehicle-mounted device 3B indicates information indicating that the exchange has been accepted with respect to the reservation management device 2 (response result of the exchange request). (Acceptance result information indicating) is transmitted (step S45: first response result information transmitting means).

  On the other hand, when the selection to reject the exchange request has been made (step S44: No), the control unit 32 of the vehicle-mounted device 3B receives information indicating that the exchange has not been accepted for the reservation management device 2 (to the exchange request). (Acceptance result information indicating the acceptance result) is transmitted (step S46: first acceptance result information transmitting means).

  Returning to step S43 described above, if there is no response selection for the exchange request information (step S43: No), the control unit 32 of the vehicle-mounted device 3B determines whether or not a predetermined time has passed without the response selection being made. Is determined (step S47).

  When the predetermined time has elapsed (step S47: Yes), the control unit 32 of the vehicle-mounted device 3B transmits information notifying that the timeout has occurred to the reservation management device 2 (step S48). Information notifying that the timeout has occurred is transmitted to the on-vehicle device 3A of the requesting vehicle A via the reservation management device 2.

  On the other hand, when the predetermined time has not elapsed (step S47: No), the process returns to step S43, and it is determined whether or not the response unit has been selected by the control unit 32 of the vehicle-mounted device 3B.

  FIG. 13 is a flowchart showing an operation by the reservation management apparatus 2 that has received the acceptance result information.

  First, when the control unit 22 of the reservation management apparatus 2 receives the acceptance / rejection result information indicating the acceptance / rejection result to the exchange request transmitted from the vehicle-mounted device 3B of the vehicle B that is the transmission destination of the exchange request (Step S51: No. 1). (3 receiving means), it is determined whether or not the information indicating the response of the received exchange request is information to accept the exchange (step S52).

  When the response result information is information for exchange (step S52: Yes), the control unit 22 of the reservation management apparatus 2 replaces the exchange candidate request stored in the charge reservation storage unit 25 based on the exchange request. (Latitude) between the charge reservation facility associated as the charge reservation information of the vehicle A that is the transmission source (request source) and the charge reservation facility associated with the charge reservation information of the vehicle B that is the request destination And longitude) and scheduled charging time (scheduled charging start time and scheduled charging end time) are exchanged, respectively. (Step S53: Exchange means). Note that the control unit 22 of the reservation management device 2 describes the exchange of the actual reservation information of the vehicle A and the actual reservation information of the vehicle B in the identification ID column of the data table of the charging facility reservation status shown in FIG. It may be performed by exchanging 10A which is the identification ID of the vehicle A and 10B which is the identification ID of the vehicle B.

  Next, the control unit 22 of the reservation management apparatus 2 stores the change contents of the data table of the charging facility reservation status after the reservation exchange, and updates the data in the charging reservation storage unit 25 (step S54).

  Next, the control unit 22 of the reservation management apparatus 2 notifies the onboard unit 3A of the requesting vehicle A and the onboard unit 3B of the requesting vehicle B that the exchange of the reservation information has been completed. (Step S55), reservation exchange ends.

  On the other hand, in the above-described step S52, when the response result information is information that does not respond to the exchange (step S52: No), the control unit 22 of the reservation management apparatus 2 is a transmission candidate request source (request source). Information notifying that the exchange has not been accepted is transmitted to the vehicle-mounted device 3A of the vehicle A (step S56).

  And the control part 22 of the reservation management apparatus 2 is exchanged as a changeable candidate with respect to onboard equipment 3A, when the replacement | exchange request | requirement is received from the onboard equipment 3A of the vehicle A which is a request origin after a predetermined time. The charging reservation storage unit 25 is set so as not to reflect the information related to the vehicle B as the extraction result (step S57), and the reservation exchange is terminated.

  As described above, according to the charging facility reservation system of the present embodiment, it is possible to quickly reserve other charging facilities that can be used when the electric vehicle cannot reach the reserved charging facility and By accepting reservations for reachable vehicles instead of reservations, the operating rate of the charging facility can be increased.

(Second Embodiment)
In the second embodiment, a case where a plurality of types of reservations are made will be described. In the present embodiment, two reservations are made: an actual reservation and a next candidate reservation. The actual reservation is a reservation made for a vacant facility made by the procedure shown in FIG. In the next candidate reservation, when the actual reservation cannot be made at the desired charging facility, the charging facility that is desired to be reserved rather than the actual reservation is reserved in an auxiliary sense. That is, the next candidate reservation is a reservation that may overlap with the charging facility and time zone of the actual reservation by another vehicle. The next candidate reservation is a reservation for enabling charging at a charging facility different from the actual reservation when the actual reservation destination charging facility cannot be reached at the actually scheduled charging start time. For this reason, when the next candidate reservation is used, there is a possibility that the reservation is exchanged with another electric vehicle.

  In the charging facility reservation system according to the present embodiment, for two vehicles A and B that are difficult to reach the actual reservation destination charging facility, the same is made in the time zone overlapping with the actual reservation of the vehicle A and the next candidate reservation of the vehicle A. It is possible to reserve a new charging facility that can be reached by exchanging with the actual reservation of the vehicle B that has reserved the charging facility.

  FIG. 14 is a block diagram schematically showing the configuration of the charging facility reservation system 1 according to the second embodiment. The charging facility reservation system 1 of the present embodiment is shown in FIG. 2 except that the charging reservation storage unit 25 is eliminated from the reservation management device 2 and an actual reservation state storage unit 27 and a next candidate reservation state storage unit 28 are added. The configuration is the same as that of the charging facility reservation system 1 of the first embodiment. Therefore, here, the actual reservation status storage unit 27 and the next candidate reservation status storage unit 28 will be described as a description of the configuration, and description of other configurations will be omitted. In addition, the same code | symbol is attached | subjected about the structure which is common in the charging facility reservation system 1 which concerns on a present Example shown in FIG. 14 and the charging facility reservation system 1 which concerns on 1st Embodiment shown in FIG. .

  FIG. 15 is a data table stored in the actual reservation status storage unit 27 of the reservation management apparatus 2. As shown in FIG. 15, the actual reservation status storage unit 27 includes, as information indicating the actual reservation status of the charging facility, the identification ID of the vehicle-mounted device mounted on each vehicle, which is identification information of the electric vehicle, from the vehicle. The charging reservation information for each electric vehicle in which the latitude and longitude that are the locations of the charging facilities reserved as the charging destination, the estimated charging start time that is the estimated charging time for each vehicle, and the estimated charging end time are stored.

  FIG. 16 is a data table stored in the next candidate reservation status storage unit 28 of the reservation management apparatus. As shown in FIG. 16, the next candidate reservation status storage unit 28 has, as information indicating the status of the next candidate reservation of the charging facility, an identification ID of the vehicle-mounted device mounted on each vehicle, which is identification information of the electric vehicle, Next candidate charge reservation information for each electric vehicle that associates the latitude and longitude, which are the locations of the charging facilities reserved as auxiliary charging destinations from the vehicle, the estimated charging start time and the scheduled charging end time for each vehicle. Remember.

  FIG. 17 is a flowchart showing a procedure for reserving an electric vehicle charging facility.

  First, the control unit 32 of the vehicle-mounted device 3A mounted on the vehicle A acquires the latitude and longitude information, which is the current position of the vehicle A, using the GPS of the navigation system 36 as the vehicle status information of the vehicle A. At the same time, the travelable distance information is acquired from the remaining battery capacity (step S61).

  Next, the control unit 32 of the vehicle-mounted device 3A obtains the latitude and longitude of the charging facility from the memory 33 as the location information of the charging facility within the travelable range based on the acquired current position and travelable distance of the vehicle A. Read and acquire the position of the charging facility (step S62). This step S62 is performed in the same manner as step S2 in the flowchart of FIG.

  Next, the control unit 32 of the vehicle-mounted device 3A transmits to the reservation management device 2 a transmission request for information on the operation status and the actual reservation status information for the charging facility whose location information has been read in step S62 (step S63). .

  The transmission request transmitted from the vehicle-mounted device 3A is accepted by the control unit 22 of the reservation management device 2. And the control part 22 of the reservation management apparatus 2 which received the said information performs the process similar to step S201-step S204 of FIG. 7 mentioned above, and extracts the charging facility and time slot | zone which can be actually reserved.

  And the control part 22 of the reservation management apparatus 2 transmits the information which shows the charging facility and time slot | zone which can be actually reserved to the onboard equipment 3A similarly to FIG.7 S205.

  Returning to the flowchart of FIG. 17, next, when the control unit 32 of the in-vehicle device 3 </ b> A receives the information indicating the charging facility and the time zone that can be actually reserved transmitted from the reservation management device 2 (Step S <b> 64), Information on rechargeable charging facilities and time zones is displayed on the display 35 (step S65). The driver selects a charging facility and a time zone for which an actual reservation is made based on the information on the charging facility and the time zone that can be actually reserved. This selection is performed by the driver operating the input unit 34 and the display unit 35.

  Next, the control unit 32 of the vehicle-mounted device 3A stores information indicating the charging facility and the time zone for performing the actual reservation selected by the driver in the memory 33 as the reservation destination of the actual reservation. (Step S66) Then, the control unit 32 of the vehicle-mounted device 3A transmits to the reservation management device 2 information indicating the charging facility and the time zone for performing the actual reservation (Step S67). The transmitted information indicating the charging facility where the actual reservation is made and the time zone is stored in the actual reservation status storage unit 27 of the reservation management device 2. Thus, the actual reservation of the charging facility is completed.

  Next, the control unit 32 of the vehicle-mounted device 3A displays information indicating the location information (latitude and longitude) of the charging facility within the travelable range acquired in step S62 on the display 35 (step S68). The driver selects a charging facility and a time zone for performing the next candidate reservation through the input unit 34 based on the information of the charging facility within the displayed travelable range.

  Here, when the next candidate reservation is made for a charging facility and time zone that overlaps with an actual reservation of another vehicle, the charging facility is closer to the charging facility where the actual reservation is made and the driver charges it there. It is preferable to select a charging facility and a time zone that have been desired but have not been able to make a real reservation because an actual reservation has been made for another vehicle in the desired time zone. This is because, as will be described later, an actual reservation similar to the next candidate reservation is extracted as a negotiation partner for exchanging the actual reservations. In other words, by setting a charging facility that initially wanted charging at a desired time zone but was unable to make a real reservation because another person had a real reservation, the extracted negotiation partner could This is because a charging facility can be included, and as a result of negotiations, an actual reservation for the facility may be obtained.

  In the present embodiment, the actual reservation similar to the next candidate reservation means that the same charging facility as the charging facility where the next candidate reservation is made is reserved, and the charging start scheduled time and the charging end scheduled time of the next candidate reservation are used. This shows an actual reservation having a charge start scheduled time and a charge end scheduled time within a predetermined range, that is, an actual reservation that overlaps at least partly with the scheduled charge time.

  Next, the control unit 32 of the vehicle-mounted device 3A stores information indicating the charging facility and the time zone in which the next candidate reservation selected by the driver is made in the memory 33 as the next candidate reservation destination (step S69).

  Moreover, the control part 32 of 3A of onboard equipment transmits the information which shows the charging facility and time slot | zone which perform next candidate reservation to the reservation management apparatus 2 (step S70).

  The information indicating the charging facility and the time zone for performing the actual reservation transmitted in step S67 is stored in the actual reservation status storage unit 27 of the reservation management apparatus 2 in the same manner as in step S207 of the flowchart shown in FIG. Further, the information on the charging facility and time zone for performing the next candidate reservation transmitted in step S70 is stored in the next candidate reservation status storage unit 28 of the reservation management apparatus 2 in the same manner as in step S207 of the flowchart shown in FIG. Therefore, explanation is omitted here. Thus, the next candidate reservation for the charging facility is completed.

  If the vehicle cannot reach the actually reserved charging facility, in this embodiment, a more preferable candidate for actual reservation is extracted based on the information on the next candidate reservation, and the extracted candidate is changed to be an actual reservation. By doing so, quick charging is possible. The procedure for changing the actual reservation will be described below.

  The driver of the vehicle A who has difficulty reaching the charging facility actually reserved at the time of the actual reservation starts the reservation changing operation. The reservation changing operation is performed by the driver operating the input unit 34 and the display unit 35.

  Here, whether or not it is difficult to reach the charging facility is determined based on the position information of the vehicle A by GPS, the reserved charging facility stored in the memory 33 and the scheduled start time of charging, the average speed of the vehicle A, the battery It is determined by the control unit 32 of the in-vehicle device 3 </ b> A based on the remaining amount.

  Then, when it is determined that it is difficult to reach the reserved charging facility, the control unit 32 of the vehicle-mounted device 3A displays on the display 35 that it is difficult to reach the charging facility. Then, the driver who sees the display can apply for replacement of the actual reservation of the charging facility. The application for exchanging the actual reservation is performed by exchanging the charging reservation information that is a candidate for exchanging the location of the charging facility and the scheduled charging time included in the charging reservation information of the actual reservation from the vehicle-mounted device 3A of the vehicle A to the reservation management apparatus 2. This is performed by transmitting information indicating a request (exchange candidate request) and transmitting information indicating the next candidate of the vehicle A (second exchange candidate request transmitting means).

  FIG. 18 is a flowchart illustrating an operation performed by the reservation management apparatus 2 that has received information indicating a request for changing an actual reservation.

  First, the control unit 22 of the reservation management apparatus 2 determines whether or not the actual reservation change request information has been received from the vehicle-mounted device 3A of the vehicle A (step S81). When the actual reservation change request information has not been received (step S81: No), the control unit 22 of the reservation management apparatus 2 waits until the actual reservation change request information is received.

  On the other hand, when the actual reservation change request information is received (step S81: Yes: fourth receiving means), the control unit 22 of the reservation management apparatus 2 reads the identification ID of the requested on-vehicle device (step S82). In this embodiment, “10A”, which is the identification number of the vehicle-mounted device 3A of the vehicle A, is read.

  Next, the control unit 22 of the reservation management apparatus 2 reads the actual reservation status from the actual reservation status storage unit 27 (step S83).

  Next, the control unit 22 of the reservation management apparatus 2 reads the next candidate reservation status from the next candidate reservation status storage unit 28 (step S84).

  Next, the control part 22 of the reservation management apparatus 2 extracts the actual reservation information of other vehicles similar to the next candidate reservation of the requesting vehicle A (step S85: second extraction means). As an actual reservation similar to the next candidate reservation, a charging facility that is the same as the charging facility reserved for the next candidate reservation is reserved, and the deviation from the scheduled charging start time and the scheduled charging end time of the next candidate reservation is within a predetermined range. An actual reservation having a certain charge start scheduled time and a charge end scheduled time, that is, an actual reservation that overlaps at least partially with the scheduled charge time is extracted.

  Next, the control unit 22 of the reservation management apparatus 2 determines whether there is a similar actual reservation information extraction result (step S86). If there is no extraction result (step S86: No), the charging facility that has made the next candidate reservation will be vacant after the next candidate reservation, so the control unit 22 of the reservation management device 2 will follow the requesting vehicle A. The candidate is changed to an actual reservation, and the data in the actual reservation status storage unit 27 and the next candidate reservation status storage unit 28 are updated (step S87: changing means).

  Next, the control unit 22 of the reservation management device 2 notifies the onboard unit 3A of the requesting vehicle A that the next candidate reservation has been changed to an actual reservation (step S88), and ends the operation.

  On the other hand, when there is an extraction result of actual reservation information similar to the next candidate reservation in step S86 (step S86: Yes), the control unit 22 of the reservation management device 2 connects the on-vehicle device 3A of the vehicle A that is the request source. The extraction result (exchangeable list) of actual reservation information (at least one or more charging reservation information to be exchange candidates) similar to the next candidate reservation is transmitted (step S89: third transmission means), and the operation is terminated.

  If there is an extraction result of actual reservation information similar to the next candidate reservation, the driver of the requesting vehicle A next selects an actual reservation to be exchanged from the extraction result. In addition, the extraction result of the real reservation information similar to the next candidate reservation is not limited to one, and there may be a plurality of results. When there are a plurality of extraction results of actual reservation information similar to the next candidate reservation, that is, the same charging facility as the charging facility reserved for the next candidate reservation, and other times overlapping with the time slot for which the next candidate reservation was made This is a case where there are a plurality of actual reservations for the vehicle.

  FIG. 19 is a flowchart showing processing by the vehicle-mounted device that has received the exchangeable list.

  First, when the control unit 32 of the vehicle-mounted device 3A mounted on the vehicle A receives an exchangeable list that is a list of charge reservation information that is exchange candidates transmitted from the reservation management device 2 (step S91: second charge reservation). (Information receiving means), the actual reservation information listed in the exchangeable list is displayed on the display 35 (step S92).

  Next, the driver operates the input unit 34 and the display 35 to select a desired one from a list of actual reservation information similar to the next candidate reservation displayed on the display 35 (charging reservation information that is an exchange candidate). When the operation is performed and information indicating the content of the operation is received, the control unit 32 of the vehicle-mounted device 3A selects the actual reservation information (step S93).

  When actual reservation information is selected (step S93: Yes), the control unit 32 of the vehicle-mounted device 3A transmits specification information for specifying the charge reservation information to be exchanged to the reservation management device 2 (step S94: second). The designated information transmitting means), a series of operations are completed. Here, the selected actual reservation information relates to the vehicle B, and the identification ID “10B” is allocated as data stored in the actual reservation status storage unit 27.

  On the other hand, when there is no selection in step S93 (step S93: No), the control unit 32 of the vehicle-mounted device 3A determines whether or not a state in which the selection is not accepted continues for a predetermined time (step S95). When the predetermined time has not elapsed (step S95: No), the process returns to step S93, and the control unit 32 waits until information indicating the content of the selection operation by the driver is transmitted.

  On the other hand, when the predetermined time has elapsed (step S95: Yes), the control unit 32 of the vehicle-mounted device 3A displays an error indicating that a time-out has occurred on the display 35 (step S96), and ends a series of operations.

  When the driver selects the actual reservation information listed in the negotiable list, an exchange request is transmitted from the in-vehicle device 3A to the reservation management device 2. Hereinafter, the operation of the reservation management apparatus 2 that has received the exchange request will be described.

  FIG. 20 is a flowchart showing the operation of the reservation management apparatus 2 that has received the exchange request information.

  First, the control unit 22 of the reservation management apparatus 2 receives an exchange request from the in-vehicle device 3A (step S101).

  Next, the control unit 22 of the reservation management device 2 searches the actual reservation status storage unit 27, confirms the data of the identification ID “10B” indicating the vehicle B that is the replacement request destination (step S102), and requests replacement. It is determined whether or not the actual reservation is held as data with the identification ID “10B” (step S103).

  When the data is stored as the data of the identification ID “10B” (step S103: Yes), the control unit 22 of the reservation management apparatus 2 stores the identification stored in the actual reservation status storage unit 27 until the result of the exchange response is obtained. The actual reservation data with ID “10B” is locked so that it cannot be changed (step S104).

  Next, the control unit 22 of the reservation management device 2 transmits the exchange request information to the vehicle-mounted device 3B of the vehicle B that is the exchange request destination (step S105), and the series of operations ends.

  On the other hand, when it is not held as the data of the identification ID “10B” in step S103 (step S103: No), the control unit 22 of the reservation management device 2 provides the on-vehicle device 3A of the vehicle A that is the request source to An error that prompts the user to select another real reservation as the exchange request destination is transmitted (step S106), and the series of operations ends.

An exchange request between the location and the scheduled charging time is received (second exchange request receiving means), and information indicating the result of the response of the exchange by the driver of the vehicle B (acceptance result indicating the result of the response to the exchange request Information) is transmitted from the vehicle-mounted device 3B to the reservation management device 2 (second response result information transmitting means). Hereinafter, the operation of the reservation management apparatus 2 that has received the acceptance result information will be described.

  FIG. 21 is a flowchart showing the operation of the reservation management apparatus that has received the acceptance result information in the second embodiment.

  First, when the control unit 22 of the reservation management apparatus 2 receives the acceptance / rejection result information indicating the acceptance / rejection result to the exchange request transmitted from the vehicle-mounted device 3B of the vehicle B that is the transmission destination of the exchange request (step S111), It is determined whether or not the received response result information is information to be exchanged (step S112).

  When the response result information is information corresponding to the exchange (step S112: Yes), the control unit 22 of the reservation management apparatus 2 exchanges the actual reservation information based on the exchange request (step S113). Specifically, the control unit 22 of the reservation management device 2 exchanges the actual reservation information of the vehicle A and the actual reservation information of the vehicle B stored in the actual reservation status storage unit 27. This exchange is performed by the control unit 22 in the actual reservation status data table (see FIG. 15) stored in the actual reservation status storage unit 27, and the location (latitude and longitude) of the charging facility of the actual reservation destination of the vehicle A and Exchange the scheduled charging time (scheduled charging start time and scheduled charging end time) with the location (latitude and longitude) of the actual charging facility of vehicle B and the scheduled charging time (scheduled charging start time and scheduled charging end time). It is done by doing.

  Note that the control unit 22 of the reservation management device 2 describes the exchange of the actual reservation information of the vehicle A and the actual reservation information of the vehicle B in the identification ID column of the data table of the charging facility reservation status shown in FIG. It may be performed by exchanging 10A which is the identification ID of the vehicle A and 10B which is the identification ID of the vehicle B.

  After the actual reservation is exchanged, the control unit 22 of the reservation management apparatus 2 deletes the data of the identification ID “10A” in the next candidate reservation status database (see FIG. 16) stored in the next candidate reservation status storage unit 28. (Step S114). In this way, the actual reservation status database and the next candidate reservation status database are updated by the control unit 22 of the reservation management apparatus 2 (step S115).

  Next, the control unit 22 of the reservation management apparatus 2 notifies the onboard device 3A of the requesting vehicle A and the onboard device 3B of the requesting vehicle B that the exchange of reservation information has been completed. Information is transmitted (step S116), and a series of operations are completed.

  On the other hand, when the response result information is information that does not respond to the exchange in step S112 (step S112: No), the control unit 22 of the reservation management device 2 exchanges the onboard device 3A of the vehicle A that is the request source. Is sent to notify that it has not been accepted (step S117).

  And the control part 22 of the reservation management apparatus 2 will be set as a changeable candidate with respect to the onboard equipment 3A, when exchange request information is received from the onboard equipment 3A of the vehicle A which is a request origin after a predetermined time. The actual reservation status storage unit 27 is set so as not to reflect the information related to the vehicle B as the exchange destination as an extraction result (step S118), and the exchange of the reservation is terminated.

  In the vehicle-mounted device 3A of the vehicle A that is the request source that has received information notifying that the exchange has not been accepted, the actual reservation is exchanged with the vehicle B.
