The battery 15 of the power-feeding vehicle 13 includes a battery that charges and discharges electric power for power feeding to the power-feed-receiving vehicle 12.
The procedures in
In S201, the power-feed-receiving vehicle 12 sends identification information, travel information, position information, and battery information, to the server device 10. The power-feed-receiving vehicle 12 sends each type of information to the server device 10 when the remaining charge of the battery falls below an optional reference and insufficient electric power is foreseen, or when the user determines that power feeding is necessary and inputs an instruction to the in-vehicle device 14 to send a power feed request. The determination reference for predicting insufficient electric power is, for example, an optional state of charge (SOC) value (30% to 40%) or less. The identification information is information that identifies the power-feed-receiving vehicle 12. The travel information includes the destination of the power-feed-receiving vehicle 12, the travel route from the current position to the destination, an estimated time of arrival, and so forth. The travel route is searched for by an automotive navigation system of the power-feed-receiving vehicle 12. When the information regarding the destination and the current position is sent from the power-feed-receiving vehicle 12 to the server device 10, and the server device 10 searches for a travel route, the server device 10 may hold the information regarding the travel route. The battery information includes information such as capacity, remaining charge, temperature, and so forth, of the battery 15. S201 is executed for each of one or more power-feed-receiving vehicles 12.
In S202, the server device 10 acquires position information and battery information from one or more power-feeding vehicles 13. The server device 10 requests various types of information for each power-feeding vehicle 13 from the one or more power-feeding vehicles 13, and acquires information sent from each power-feeding vehicle 13 in response to the request. The battery information includes information regarding the capacity and the remaining charge in the battery 15.
In S203, the server device 10 creates a power feed proposal. The power feed proposal includes either or both of facility information indicating a power feed facility near the travel route of the power-feed-receiving vehicle 12, and rendezvous information indicating a rendezvous point where the power-feed-receiving vehicle 12 can rendezvous with the power-feeding vehicle. Detailed procedures of S203 are shown in
In S301, the control unit 103 derives a travelable range. The travelable range is a range of distance that the power-feed-receiving vehicle 12 can travel on the remaining charge in the battery 15, along the travel route of the power-feed-receiving vehicle 12. The control unit 103 derives the travelable range using an optional algorithm, based on the identification information, the position information, and the battery information, acquired from the power-feed-receiving vehicle 12. For example, the control unit 103 derives the travel distance that the power-feed-receiving vehicle 12 is capable of traveling on the remaining charge in the battery 15 based on the identification information regarding the power-feed-receiving vehicle 12. The storage unit 102 stores identification information regarding the power-feed-receiving vehicle 12 so as to be associated with specification information regarding the vehicle, including mileage per unit electric power. The control unit 103 uses the mileage per unit electric power to derive a range of distance that can be traveled on the remaining charge in the battery 15 at that time, centered on the current position of the power-feed-receiving vehicle 12. The control unit 103 similarly derives a travelable distance range corresponding to passage of an optional period of time (e.g., several tens of minutes to several hours from the current time). The control unit 103 then derives a sum set of the derived travelable distance ranges over time, as the travelable range.
Returning to
In S304, the control unit 103 ranks the power feed facilities. The control unit 103 ranks the power feed facilities in order of how short waiting time is from the arrival of the power-feed-receiving vehicle 12 until the power feed facility becomes available. For example, the control unit 103 acquires information regarding reservations for power feeding at each power feeding facility from a server that manages and controls the power feeding facilities. Further, the control unit 103 uses the position information regarding each power feed facility to derive an estimated arrival time at which the power-feed-receiving vehicle 12 can arrive at each power supply facility from the current position. The control unit 103 then derives, for each power feed facility, the waiting time from the estimated arrival time of the power-feed-receiving vehicle 12 to the time when the power supply facility will become available, and ranks the power feed facilities in order of how short the waiting time is.
In S305, the control unit 103 generates information for displaying the power feed facilities. The control unit 103 generates an image for display by superimposing, on a map, the position, the destination, and the travel route, of the power-feed-receiving vehicle 12, positions of the power feed facilities, and ranks thereof.
In S306, the control unit 103 derives rendezvous points within the travelable range of the power-feed-receiving vehicle 12. A rendezvous point is a parking lot at which space can be secured for the power-feed-receiving vehicle 12 and the power-feeding vehicle 13 to park adjacent to each other. The control unit 103 searches for parking lots within the travelable range of the power-feed-receiving vehicle 12, as rendezvous points, from the map information.
In S308, the control unit 103 ranks the rendezvous points. The control unit 103 ranks the rendezvous points in order of how short the waiting time is from the power-feed-receiving vehicle 12 arriving until the power-feeding vehicle 13 arrives. For example, the control unit 103 uses the position information regarding each power-feeding vehicle 13 to identify the power-feeding vehicle 13 nearest to each rendezvous point. At this time, the control unit 103 may set conditions for selecting the nearest power-feeding vehicle 13, in which the remaining charge in the battery 15 of the power-feeding vehicle 13 is no less than an optional reference value (e.g., 50% in terms of SOC value). Furthermore, the control unit 103 derives the estimated arrival time at which the nearest power-feeding vehicle 13 can arrive at each rendezvous point. The control unit 103 then derives the waiting time from the estimated arrival time of the power-feed-receiving vehicle 12 to the estimated arrival time of the power-feeding vehicle 13 for each rendezvous point, and ranks the rendezvous points in order of how short the waiting time is.
In S309, the control unit 103 generates information for displaying the rendezvous points. The control unit 103 generates an image for display by superimposing, on the map, the position, the destination, the travel route, of the power-feed-receiving vehicle 12, positions of the rendezvous points, and ranks thereof.
In S310, the control unit 103 generates power feed proposal information. The control unit 103 generates an image for displaying power feed facilities, or an image obtained by combining this with an image for displaying rendezvous points, as an image for power feed proposal. That is to say, the image for power feed proposal is an image in which the position, the destination, and the travel route, of the power-feed-receiving vehicle 12, and the positions and ranks of the power feed facilities, are superimposed on the map, or an image in which the positions and ranks of the rendezvous points are superimposed on this image.
Returning to
Returning to
When a rendezvous point is selected, the server device 10 sends a travel instruction to the power-feeding vehicle 13 in S206. The travel instruction is sent to the power-feeding vehicle 13 nearest to the selected rendezvous point. The travel instruction includes information regarding the travel route to the rendezvous point, and a travel start time at which travelling should start. The travel route is derived based on the rendezvous point and the position of the power-feeding vehicle 13. Also, the travel start time is derived based on the travel route.
In S209, the power-feeding vehicle 13 is dispatched in response to the travel instruction. When the travel start time comes, the power-feeding vehicle 13 starts traveling by automated driving in accordance with the travel route. Alternatively, the power-feeding vehicle 13 displays the travel route to an occupant, and starts traveling in response to being manipulated by the occupant.
In S208, the server device 10 sends information regarding the travel route to the power-feed-receiving vehicle 12. When a rendezvous point is selected under consent to the power feed proposal in S205, the server device 10 derives the travel route from the current position of the power-feed-receiving vehicle 12 to the rendezvous point that is selected. Alternatively, when a power feed facility is selected under consent to the power feed proposal in S205, the server device 10 derives the travel route from the current position of the power-feed-receiving vehicle 12 to the power feed facility that is selected. Note that in this case, S206 and S209 are omitted. In the power-feed-receiving vehicle 12, the travel route to the rendezvous point or the power feed facility is displayed, and the user confirms the displayed travel route.
In S210, the power-feed-receiving vehicle 12 starts traveling along the travel route.
In S211, the power-feed-receiving vehicle 12 arrives at the rendezvous point, rendezvouses with the power-feeding vehicle 13, and receives power feeding from the power-feeding vehicle 13, or arrives at the power feed facility and receives power feeding from the power feed facility.
According to an arrangement such as described above, the power-feed-receiving vehicle 12 can acquire either one or both of information regarding the location of the power feed facility near the travel route and information regarding the rendezvous point where roadside charging can be received from the power-feeding vehicle 13, and accordingly the user of the power-feed-receiving vehicle 12 can incorporate a plan for power feeding into the travel plan. Even when traveling through an area where power feed facilities are sparse, the user of the power-feed-receiving vehicle 12 can incorporate a plan for power feeding by roadside charging at a rendezvous point. Furthermore, taking ranking information for each rendezvous point or each power feed facility into consideration enables the user to make a selection to shorten the waiting time. Further, according to the modification, the user can comprehend the estimated arrival time at the destination or delay time. Thus, convenience of power feeding can be improved.
