  2. Description of the Related Art Conventionally, a car navigation apparatus that can search for a gas station or the like as a destination and perform route search and route guidance has been used. A car navigation device capable of guiding a charging station for an electric vehicle has also been proposed. However, unlike charging of fuel such as gasoline or hydrogen, charging a battery in an electric vehicle usually takes a certain time or more. For this reason, even if a charging station or a rechargeable parking lot is searched and searched for as a destination, and route guidance is provided, charging cannot be performed or sufficient charging time cannot be ensured depending on the usage status of the power supply equipment. For this reason, there is a possibility that the remaining battery level required for the subsequent running cannot be secured. Such a problem is a problem common to all moving bodies driven using electric power.

  In view of the above-described problems, an object of the present invention is to provide an appropriate power supply environment according to the use situation of power supply equipment for a mobile body driven by power.

In order to solve the above problems, the present invention includes the following means in the server device. That is, the present invention is a server device communicably connected to an information processing device mounted on a vehicle driven by electric power from a battery, wherein the vehicle is connected to a power feeding facility capable of supplying power to the battery. Vehicle information acquisition means for acquiring vehicle information including information capable of grasping an estimated arrival time and a stay time of the vehicle at the power supply facility; and a schedule for using the power supply facility according to the estimated arrival time and the stay time. A utilization schedule acquisition means for acquiring; a power supply plan creation means for creating a power supply plan for the power supply facility recommended for the vehicle at the estimated arrival time and the stay time based on the utilization schedule and the vehicle information; A power supply plan output means for outputting the power supply plan to the information processing device; and an output of the power supply plan. Reservation accepting means for accepting a reservation application for use of the power supply facility including the vehicle identification information from the information processing device, and the vehicle identification information included in the reservation application, for the estimated arrival time and the stay time. And a usage schedule updating unit that updates the usage schedule in association with a usage frame of the power supply facility.

  As described above, charging a battery usually takes a certain amount of time, and temporarily searches for a destination having a power supply facility as a destination (for example, a charging station or a chargeable parking lot) and a route search. However, even if route guidance is provided, depending on the usage status of the power supply equipment, it is necessary to secure the remaining battery level for subsequent driving because charging is not possible or sufficient charging time cannot be secured. May not be possible. Therefore, in the present invention, a power supply plan to be presented to the vehicle is created according to the vehicle information and the power supply facility usage schedule, and the power supply facility is reserved according to the power supply plan. We decided to provide an appropriate power supply environment.

  A server device according to the present invention is a server device having a function of accepting a power supply reservation from an information processing device such as a car navigation device mounted on a vehicle driven by power from a battery mounted on the vehicle.

When the power supply reservation process according to the present invention is executed at the start of travel or during travel, the remaining battery level at the time of processing reference is the remaining battery level at the time of processing (current). When the power supply reservation process is executed in advance based on the above and the power supply facility is reserved before the start of traveling, the processing reference time is a time such as a travel start time in the operation schedule, and is acquired in this case. The remaining battery level at the time of processing reference is acquired by predicting the remaining battery level at a future time when the remaining battery level needs to be acquired, such as a predetermined time in the operation schedule.

  The power supply facilities may have different power supply capabilities. The amount of power that can be charged during the stay depends on the stay time. For this reason, in this invention, it is supposed that the judgment material for performing more advantageous electric power feeding will be provided by estimating the battery remaining charge after a stay.

  In addition, the server device according to the present invention obtains the identification information of the vehicle when the vehicle enters the power supply facility, and authenticates the entering vehicle by collating with the identification information of the updated use schedule. And a power supply permission issuing means for issuing a power supply permission for the authenticated vehicle to the power supply facility.

  By issuing the vehicle authentication and the power supply permission issuance by the authentication unit and the power supply permission issuing unit, the facility in the power supply facility (specifically, the parking space where the power transmission unit is installed) is changed to the estimated arrival time of the vehicle. It is possible to ensure adequately.

  FIG. 4 is a diagram illustrating a functional configuration of the in-vehicle device 1 according to the present embodiment. In the information processing apparatus according to the present embodiment, the CPU 13 interprets and executes the destination search program developed in the RAM 10, so that the input reception unit 21, the destination candidate search unit 22, the route search unit 23, the arrival Pre-necessary remaining amount prediction unit 24, battery remaining amount acquisition unit 25, arrival battery level prediction unit 26, post-stay required remaining amount prediction unit 27, stay time acquisition unit 28, post-stay battery level prediction unit 29, destination It functions as the vehicle-mounted device 1 including the candidate narrowing-down unit 30, the output unit 31, the reservation processing unit 32, and the route guide unit 33.

  The destination candidate searching unit 22 searches for a destination candidate that matches the search condition from the point information database. In the present embodiment, the destination candidate searching unit 22 compares the necessary remaining amount before arrival with the current battery remaining amount, and searches only for destination candidates that can be reached with the current battery remaining amount. In addition, the route search unit 23 searches for a route to the destination candidate with reference to the map data.

The required remaining amount prediction unit 24 before arrival predicts the necessary remaining amount before arrival required for traveling to the destination candidate by calculating the power consumption when traveling on the travel route searched by the route search unit 23. . In addition, the post-stay required remaining amount predicting unit 27 predicts the post-stay required remaining amount by calculating power consumption when traveling on the travel route after stay searched by the route searching unit 23.

And the destination candidate narrowing-down part 30 narrows down the destination candidate provided with the electric power feeding equipment from which the battery remaining amount after stay exceeds the required remaining amount after stay from the searched destination candidate. Note that, in this embodiment, the destination candidate narrowing unit 30 narrows down to destination candidates provided with power supply facilities when the battery level at arrival is lower than the necessary remaining amount after staying.

<Details of destination search processing>
5 and 6 are flowcharts showing the flow of the destination search process according to the present embodiment. The processing shown in this flowchart is started when a search condition for searching for a destination is input. Note that the specific contents and order of the processes shown in this flowchart are examples, and it is preferable that processes suitable for the embodiment are appropriately adopted as the process contents and order.

  Note that, in the present embodiment, mainly the case of executing the destination search process at the start of traveling or during traveling, the remaining battery level at the time of the processing reference acquired in the processing described later is the processing The battery level at the time (current), but when the destination search process is executed in advance based on the operation schedule before the start of driving and the advance plan for using the power supply facility is created, The remaining battery level acquisition unit 25 predicts and acquires the remaining battery level at a future time when the remaining battery level needs to be acquired, such as a predetermined time in the schedule. To do.

  Here, the operation schedule is information including a vehicle operation plan for a predetermined period, for example, one or a plurality of destinations (including final destinations), estimated arrival times for each destination, and at each destination. It includes the staying time, scheduled departure time for each destination, information for designating a route to be preferentially searched (whether toll roads can be used, etc.), and the like. By executing the destination search process in advance based on the operation schedule and creating an advance plan for using the power supply equipment, it is possible to make a detailed plan including the charging plan before the actual operation of the vehicle. .

  In step S101, an input of search conditions for searching for a destination is accepted. The input receiving unit 21 is a search condition input by a user via an input / output device 8 such as a touch panel display or buttons provided in the in-vehicle device 1, an auxiliary storage device built in the in-vehicle device 1, or an external storage device. The input of the search condition read from is received (step S101). Note that the input search conditions may simply be one or a plurality of search conditions, or may be input in the form of an operation schedule including more detailed information. Thereafter, the process proceeds to step S102.

  In steps S102 and S103, a destination candidate search and a route search are performed. When the search condition is received by the input receiving unit 21, the destination candidate searching unit 22 searches for point information stored in the point information database in accordance with the search condition, thereby searching for a destination candidate that matches the search condition. (Step S102). In addition, the route search unit 23 refers to the map data and searches for a route (route) to the searched destination candidate (step S103). Note that the search for the destination candidate and the route search can be performed using the search technology and search technology used in the conventional car navigation system, and thus detailed description thereof is omitted. Thereafter, the process proceeds to step S104.

In step S104, the remaining battery capacity required to reach the destination candidate (hereinafter also referred to as “required remaining capacity before arrival”) is predicted. The required remaining amount prediction unit 24 before arrival calculates the remaining battery amount required to arrive at the destination candidate when traveling to the destination candidate through the route searched in step S103.

  The required remaining amount until the destination candidate (required remaining amount before arrival) is most simply calculated by multiplying the power consumption per mileage by the distance of the search route or the power consumption per travel time to the destination candidate. It can be calculated using a method of multiplying the travel time until. However, in order to calculate the required remaining amount before arrival more accurately, the required remaining amount prediction unit 24 before arrival determines the power consumption such as the inclination of the route, time zone, season, temperature, traffic information, the driver's accelerator operation tendency, etc. It is also possible to collect information on factors that affect the amount of information and calculate the necessary remaining amount before arrival by taking these information into account. For example, when an element that affects some electricity consumption is acquired by collecting information, a more accurate pre-arrival required residue can be obtained by setting a coefficient according to the degree of the element and correcting the required remaining amount before arrival. The amount can be predicted. Note that various units such as the amount of power, time, distance, or a load expressed in a unique format may be adopted as a unit of the necessary remaining amount before arrival calculated.

  In steps S105 and S106, the remaining battery level at the time of processing reference (current when the destination search process is executed during operation) is acquired and compared with the required remaining amount before arrival for each destination candidate. . The remaining battery level acquisition unit 25 acquires the remaining battery level from the charge / discharge control device 131 of the in-vehicle battery 133 mounted on the vehicle (step S105). The remaining battery level acquired here may be in a format that can be compared with the remaining battery level necessary to reach the destination candidate. For example, the ratio to the full charge, the travelable time, the travel time It can be obtained in the form of possible distance. The acquired battery remaining amount is converted into a comparable form if necessary, and compared with the necessary remaining amount before arrival predicted in step S104 (step S106). Thereafter, the process proceeds to step S107.

  In steps S107 and S108, the destination candidates are narrowed down according to the comparison result, and the remaining battery level at the time of arrival at the destination candidate (hereinafter also referred to as “the remaining battery level at arrival”) is predicted. The destination candidate searching unit 22 determines whether each destination candidate is reachable with the remaining battery level at the time of the processing reference based on the comparison result in step S106 (step S107). Then, the arrival battery level prediction unit 26 calculates the arrival battery level for the destination candidate determined to be reachable with the remaining battery level at the processing reference (step S108). Specifically, the battery level prediction unit 26 at the time of arrival is based on the battery level at the time of processing reference and the power consumption when traveling to the destination candidate on the route obtained as a result of the search in step S103. Calculate battery level on arrival. For example, if the remaining battery power and power consumption are expressed in terms of travel time, travel distance, etc., it can be calculated by simply subtracting the power consumption when driving from the remaining battery power at the time of processing to the destination candidate. It is. Thereafter, the process proceeds to step S109.

  In step S109, the necessary remaining amount after stay necessary for traveling after the destination stay is predicted. After the stay at the destination candidate ends and the destination candidate is departed, the post-stay required remaining amount predicting unit 27 further includes a destination having the next charging facility and a final destination (such as home) in a series of operation schedules. Calculate the required remaining amount after staying required for traveling until. For this reason, the route search unit 23 searches for a route after leaving the destination candidate. Then, the required remaining amount prediction unit 27 after staying uses the route search result after the destination stay by the route search unit 23, and travels through the searched route, the next destination that can be supplied with power or the final destination By calculating the remaining battery capacity required to arrive at the destination, the required remaining capacity after the stay is predicted. The specific calculation method of the required remaining amount is substantially the same as the calculation of the remaining battery amount necessary for arrival at the destination candidate by the required remaining amount prediction unit 24 before arrival described in step S104. Omitted. Thereafter, the process proceeds to step S110.

In step S110, based on the power supply capacity of the power supply facility, the remaining battery level at arrival, and the staying time, the remaining battery level at the time of departure of the destination candidate when staying at the destination candidate (hereinafter referred to as “battery remaining after staying”). Also referred to as “amount”). The stay time acquisition unit 28 accepts input by the user via the input / output device 8, acquires from a previously created operation schedule, or estimates from attribute information of the destination candidate, etc. Get stay time. When acquiring from the operation schedule, the stay time can be acquired by predicting the estimated arrival time at the destination candidate and calculating the difference from the departure time scheduled in the operation schedule. The estimated arrival time can be calculated most simply by adding the travel time calculated by dividing the distance of the searched route by the average vehicle speed or the like to the processing reference time (for example, the current time). However, more accurate estimated arrival time may be calculated by considering information based on traffic jam information and the like.

  Here, the attribute information of the destination candidate is information indicating the character of the staying place that is the destination candidate (preferably information that can be estimated how long the user stays). For example, if the attribute of the destination candidate is a convenience store, the stay time acquisition unit 28 can predict the stay time as several minutes, and if the attribute of the destination candidate is a shopping center, The time can be predicted as several hours. Moreover, as such a staying time, the user's average staying time for every point information etc. which were accumulate | stored in the point information database, the information center 2, the electric power feeding equipment management server 3, etc. can be used.

  The post-stay battery level prediction unit 29 acquires information such as the power supply capability of the power supply facility from the information center 2 or each power supply facility via the network, and arrives at the power supply facility capability obtained by this information. To what extent the remaining battery level is restored is calculated. For example, if a destination candidate has a power supply facility that can be charged quickly, the power supply amount per unit time at the destination candidate increases, so even if the stay time is short, the remaining battery level is required after the stay. It is possible to recover more than the remaining amount. The power supply capability can be indicated using a map or the like indicating the relationship between the elapsed time from the start of power supply and the remaining battery level. In this way, the post-stay battery level prediction unit 29 predicts the post-stay battery level when charging during the stay is completed. Thereafter, the process proceeds to step S111.

  In step S111, destination candidates are narrowed down according to the remaining battery level after stay and the necessary remaining amount after stay. The destination candidate narrowing-down unit 30 further narrows down the destination candidates from the destination candidates determined to be reachable with the remaining battery level at the time of processing reference in step S107. Specifically, the destination candidate narrowing-down unit 30 uses the destination candidate power supply equipment by narrowing down the destination candidates to destination candidates whose remaining battery level after staying is equal to or greater than the necessary remaining amount after staying. When power supply for the destination stay time is performed, a destination candidate having a power supply facility capable of recovering the remaining battery level from the remaining battery level upon arrival to the required remaining level after staying is searched for. Thereafter, the process proceeds to step S112.

  Note that, in this embodiment, the destination candidate narrowing unit 30 narrows down to destination candidates provided with power supply facilities when the remaining battery level at arrival is lower than the necessary remaining amount after staying. In this way, if the remaining battery level at arrival is sufficient and charging is not required during the stay, the destination candidate not equipped with the power supply facility is targeted for search, and A wider range of destination candidates. Further, in narrowing down the destination candidates having the power supply facility, the above-described power supply facility information is referred to, and it is determined whether it is suitable for the power receiving unit of the vehicle. Specifically, the transmission method shown in the power supply facility information, the installation position of the coil in the parking space, the movable range of the coil, the diameter of the coil, the resonance frequency, etc. The diameter, whether or not it is within the range of the adjustable resonance frequency, etc. are determined, and narrowing down to appropriate destination candidates is performed.

In steps S112 and S113, the destination candidate and the remaining battery level after stay are output,
Selection of a destination by the user is accepted. The output unit 31 outputs to the input / output device 8 such as a touch panel display the one or a plurality of destination candidates that have been narrowed down to step S111, and the remaining battery power when each destination candidate is selected. Is notified (step S112). At this time, the output unit 13 gives priority to the narrowed-down destination candidates (for example, in order of the remaining battery level after staying), so that the user can grasp an advantageous destination candidate regarding the remaining battery level. Can be made easier. Further, the output unit 31 causes the input / output device 8 to display a message prompting the user to select a destination, and the input receiving unit 21 receives the destination selected by the user via the input / output device 8 (step S113). ). When the selection result by the user is accepted, the process proceeds to step S114.

  In step S114, a reservation process is performed. The reservation processing unit 32 acquires the use schedule (reservation information or vacancy information) at the estimated arrival time at the destination when the power supply facility of the destination selected by the user is a reservable facility. Perform reservation processing. The estimated arrival time acquired in step S110 can be used as the estimated arrival time.

  More specifically, the use schedule of the power supply facilities may be managed by the information center 2 that centrally manages each power supply facility, or is managed by the power supply facility management server 3 installed for each power supply facility. May be. The reservation processing unit 32 acquires the power supply facility usage schedule at the estimated arrival time from the information center 2 or the power supply facility management server 3 via the network. Then, the reservation process is performed by transmitting a reservation application for designating the power supply facility and the use time zone together with information capable of identifying the host vehicle. The information center 2 or the power supply facility management server 3 that has received the reservation application updates the use schedule by storing information that can identify the vehicle of the reservation application transmission source in association with the power supply facility and the use time zone. Thereafter, the process proceeds to step S115.

  In step S115, route guidance is started. In addition, when the purpose of the destination search process shown in this flowchart is to create a prior plan based on the operation schedule, the processes after step S115 are executed after the actual operation of the vehicle is started. The route guidance unit 33 starts route guidance to the destination designated by the user in step S111 for the user by image output to the touch panel display, voice output via a speaker, or the like. The route guidance is performed according to the route searched in step S103. Since the route guidance can be performed using a route guidance technique used in a conventional car navigation system, detailed description thereof is omitted. Thereafter, the process proceeds to step S116.

  In step S116, it is determined whether or not the destination has been reached. When the vehicle arrives at the destination, the route guidance ends and the processing shown in this flowchart ends. If the destination has not been reached, the route guidance is continued and the process proceeds to step S103. That is, in the process shown in this flowchart, a route search process (so-called “replan” or “reroute”) from the current position is repeated periodically or continuously during route guidance.

At this time, the in-vehicle device 1 collects information related to the power consumption tendency such as the driving tendency of the driver and traffic jam information and reflects it in the repeated destination search process. For example, if it is determined that it is difficult to reach the destination that was originally the destination due to increased traffic remaining due to traffic jams, There may be a case where it is determined that charging at the destination is not sufficient for subsequent driving. In such a case, according to the example shown in the present embodiment, the processing after step S103 is performed again, thereby narrowing down to destination candidates that are different from the current destination, and the purpose for the user is determined. You can encourage changes in the ground.

  According to the vehicle-mounted device 1 and the destination search method according to the present embodiment, in a vehicle that is powered by using battery power, the battery for traveling due to the fact that it takes a certain time or more to charge the battery. The possibility that the remaining amount is insufficient can be reduced, and appropriate charging according to the destination and the operation schedule can be performed. In particular, in a power feeding system that performs power feeding by wireless power transmission, users can obtain information on power feeding equipment in advance, find destination candidates that meet the power feeding equipment standards, and obtain sufficient power feeding. It is possible to guide an appropriate destination candidate.

<Configuration of server device>
In the present embodiment, at least one of the information center 2 and the power supply facility management server 3 corresponds to the server device of the present invention. Each of the information center 2 and the power supply facility management server 3 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a HDD (Hard Disk Drive), an input / output device, and the like. Connected information processing apparatuses (not shown). Here, the roles played by the CPU, RAM, HDD, input / output device and the like are substantially the same as those of the vehicle-mounted device 1, and thus the description thereof is omitted.

  The HDD stores various data used by the information center 2 or the power supply facility management server 3 in addition to various programs such as a power supply reservation acceptance program loaded in the RAM. Specifically, the HDD stores power supply facility information including a use schedule related to each power supply facility.

  In the present embodiment, the usage schedule is information that allows the usage schedule of the power supply facility to be grasped, and includes reservation information or vacancy information. In the usage schedule, there is a usage frame defined by the combination of the power supply facility and the time zone, and the vehicle's identification information is stored in association with each usage frame, so that the usage schedule of the power supply facility can be determined. Retained.

  FIG. 7 is a diagram illustrating a functional configuration of the information center 2 or the power supply facility management server 3 according to the present embodiment. The information center 2 or the power supply facility management server 3 (hereinafter also simply referred to as “server device”) according to the present embodiment allows the CPU 13 to interpret and execute the power supply reservation reception program developed in the RAM 10 to obtain vehicle information. It functions as a server device that includes an acquisition unit 41, a usage schedule acquisition unit 42, a power supply plan creation unit 43, a power supply plan output unit 44, a reservation reception unit 45, a usage schedule update unit 46, an authentication unit 47, and a power supply permission issue unit 48. .

  The power supply plan creation unit 43 creates a power supply plan for the power supply facility recommended for the vehicle at the estimated arrival time and the stay time based on the use schedule and the vehicle information. For example, the power supply plan creation unit 43 is created on the basis of information that can be used to determine whether or not to reserve a use frame, information related to the power supply facility, the remaining battery level at arrival, and the stay time, which are created with reference to the use schedule. A power supply plan including the remaining battery level after staying when the user stays at the power supply facility is created.

<Details of reservation processing>
Next, the contents of the reservation process used in the power supply system according to this embodiment will be described. FIG. 8 is a flowchart showing the flow of the reservation process according to the present embodiment. The reservation process shown in this flowchart is a more detailed description of the process in step S114 shown in FIG. 6, and triggered by the user's selection of a destination (step S113). Executed. Note that the specific contents and order of the processes shown in this flowchart are examples, and it is preferable that processes suitable for the embodiment are appropriately adopted as the process contents and order.

  In steps S201 and S202, a usage schedule is inquired. The reservation processing unit 32 of the in-vehicle device includes information that can identify the vehicle on which the in-vehicle device is mounted (hereinafter also referred to as “vehicle identification information”), an estimated arrival time, a stay time after arrival, and a user identifier. And a request message for acquiring a utilization schedule of the power supply facility is transmitted to the server device via the network (step S201). The use schedule of the power supply facilities may be managed by the information center 2 that centrally manages each power supply facility, or may be managed by the power supply facility management server 3 installed for each power supply facility. Here, as the estimated arrival time, the estimated arrival time acquired in step S110 can be used. Further, in addition to the information described above, the request message may include other information such as the standard / specification of the power receiving unit provided in the vehicle, the remaining battery level at the time of processing reference, the route planned to travel, and the like. When the vehicle information acquisition unit 41 of the server device receives the request message (step S202), the process proceeds to step S203.

  In steps S203 to S205, a usage schedule is acquired and notified to the in-vehicle device. In response to a request from the in-vehicle device, the use schedule acquisition unit 42 of the server device acquires the use schedule of the power supply facility during the staying time after the estimated arrival time in the power supply facility information (step S203). The usage schedule is information related to the use of the power supply facility among the power supply facility information held by the server device, and the availability information of the power supply facility and the reservation information (information indicating the reservation status of reservation slots related to other vehicles) )including. The usage schedule may include information such as remaining power supply time of power supply equipment used by other vehicles, in addition to the vacant information and reservation information. The power supply plan output unit 44 of the server device uses the acquired usage schedule via the network together with other information, for example, information for charge calculation (power supply rate, etc.) and point service information associated with the user identifier. The data is transmitted to the in-vehicle device (step S204), and the reservation processing unit 32 of the in-vehicle device receives the usage schedule and acquires it (step S205). Thereafter, the process proceeds to step S206.

  In steps S206 and S207, the use schedule of the power supply facility is confirmed, and if the reservation is possible, a reservation instruction (selection) by the user is accepted. The reservation processing unit 32 of the in-vehicle device refers to the use schedule acquired in step S205 and determines whether or not the power supply facility can be used when the arrival time arrives at the destination (see FIG. Step S206). Specifically, whether or not the power supply facility can be used is determined based on whether the facility is available at the estimated arrival time based on the availability information or reservation information, This is performed by determining whether or not the power receiving unit corresponds to the power receiving unit, whether or not the power supply facility has a power transmission capability sufficient to receive power during the staying time, and the like.

  As a result of the determination, if the power supply facility is unavailable (or unsuitable for use) at the estimated arrival time, the in-vehicle device notifies the user to that effect using the output unit 31 and searches for the destination again. Execute the process. As a result of the determination, if the power supply facility is available (or suitable for use) at the estimated arrival time, the in-vehicle device uses the output unit 31 to reserve the power supply facility for the user. A notification prompting confirmation of whether or not it is good and a notification of information (charge, power supply rate, point service information, etc.) acquired in step S205 are sent (step S207). Thereafter, the input receiving unit 21 receives a reservation instruction operation or a cancel operation by the user. Thereafter, the process proceeds to step S208.

In steps S208 to S210, a reservation application for using the power supply facility, a reservation reception, and a reservation content are stored. The reservation processing unit 32 of the in-vehicle device, when there is a vacancy in the use schedule at the estimated arrival time, receives a reservation instruction operation by the user, the power supply equipment and the use time zone together with the vehicle identification information to the server device. The designated reservation application is transmitted (step S208). The reservation reception unit 45 of the server apparatus receives the reservation application (step S209), and the use schedule update unit 46 obtains the identification information of the vehicle that is the transmission source of the reservation application, the power supply facility to be reserved and the use time zone (estimated arrival time). The usage schedule is updated by storing in association with the usage frame specified by the time and the staying time (step S210). Thereafter, the process proceeds to step S115 shown in FIG. 6, and route guidance is started.

  Next, the flow of processing when the reserved vehicle arrives at the destination and actually uses the power supply facility will be described. FIG. 9 is a flowchart showing a flow of power supply processing based on reservation according to the present embodiment. The power supply process shown in this flowchart is executed when the reservation process shown in FIG. 8 is completed and the vehicle has arrived at the destination by the route guidance shown in FIG. Note that the specific contents and order of the processes shown in this flowchart are examples, and it is preferable that processes suitable for the embodiment are appropriately adopted as the process contents and order.

  In steps S301 to S303, authentication at the time of entering the power supply facility is performed, and whether or not there is a reservation is confirmed. The authentication is performed by the authentication unit 47 of the server device obtaining information that can identify the vehicle using a method such as communication or sensing (steps S301 and S302). The reservation processing unit 32 of the in-vehicle device may also obtain information that can identify the power supply facility using a method such as communication or sensing, and determine whether the power supply facility is set at the destination. . Specific technologies for authentication include DSRC (Dedicated Short Range Communication), authentication technology by communication via a mobile phone network, and license plate images taken by a camera provided at the warehousing gate. A technique for authenticating the vehicle by image recognition may be used.

  When acquiring the vehicle identification information, the authenticating unit 47 refers to the use schedule and determines whether or not the vehicle identification information stored in step S210 is stored as the identification information indicating the reserved vehicle in the use schedule. Then, it is determined whether or not there is a power supply reservation for the vehicle related to the acquired identification information (step S303). If the identification information matches as a result of the comparison between the acquired identification information and the identification information stored in the use schedule, the vehicle is authenticated as a vehicle related to the power supply reservation. If there is no reservation for the vehicle, the process proceeds to step S304. If it is confirmed that there is a reservation for the vehicle, the process proceeds to step S305.

  In step S304, a response process for a vehicle for which no reservation exists is executed. The server device outputs a warning, an alarm, or the like to the vehicle user in the power supply facility or the in-vehicle device, or closes the entry gate to the power supply facility, so that the vehicle without reservation uses the power supply facility. To prevent that. However, if the power supply facility is empty when the vehicle arrives at the destination, power may be supplied to the vehicle. When power supply is performed, the use schedule update unit 46 of the server device supplies information that can identify the vehicle obtained in the authentication process to the power supply facility and the use time zone (in this case, the time zone corresponding to the stay time from the current time). Update the usage schedule by associating and saving. Thereafter, the processing shown in this flowchart ends.

  In steps S305 and S306, power is supplied to the vehicle for which the presence of the reservation is confirmed. When the vehicle is authenticated and the existence of the reservation is confirmed, the power supply permission issuing unit 48 issues a power supply permission for the authenticated vehicle to the power supply facility. Upon receiving the issuance of power supply permission, the power transmission unit starts power transmission (step S305), and the power reception unit starts power reception (step S306). Since the details of the power supply are as described with reference to FIG. 2, the description is omitted here. When the power supply to the vehicle set in the usage schedule is completed, the processing shown in this flowchart ends.

  According to the power supply system shown in the present embodiment, it is possible to acquire a reservation schedule and other information related to the power supply facility, select an appropriate power supply facility, and make a reservation for use (securing a use frame) in advance. Here, the usage frame for power supply is reserved using the estimated arrival time, so when the reserved vehicle arrives at the power supply facility, power cannot be supplied because another vehicle is using the power supply facility. The situation can be prevented.

  In the above-described embodiment, the destination is determined from the destination candidates according to the user's selection operation in step S113, and the reservation process is performed for the predetermined destination. Instead of the processing order for determining the ground, another processing order may be adopted. For example, use schedule information is acquired for one or more destination candidates, information is provided to the user, and whether the destination candidate and each destination candidate can be reserved can be reserved. In this case, a processing order may be adopted in which the user determines the destination after indicating information such as what kind of power supply facility can be reserved, and reserves the power supply facility of the determined destination. In addition, when there are a plurality of destination candidates, it may be narrowed down to destination candidates that can be reserved with reference to the use schedule related to each destination candidate. The narrowing down of the destination candidates is performed in consideration of, for example, the specifications of the power supply equipment, the remaining travel distance to the destination candidates, the stay time at the destination candidates, the vacancy schedule of the power supply equipment, and the like.

  In the present embodiment, the server device may create a power supply plan for presenting a recommended power supply plan to the user and provide it to the user. The server device creates a power supply plan with reference to information acquired from the in-vehicle device and presents it to the user. Specific contents presented by the power supply plan include, for example, presentation of the time required until the amount of charge desired by the user (“Full charge possible in XX minutes”, etc.) Presenting remaining battery power, presenting charges, using point services and adding points, presenting discounts on parking charges and power supply charges (such as “free parking for purchases over ¥ ○, discount on power supply charges”, etc.), etc. May be included.

  FIG. 10 is a flowchart showing a flow of reservation processing in which a power supply plan is presented from the server device according to the present embodiment. The reservation process shown in this flowchart is executed in place of the reservation process shown in FIG. Note that the specific contents and order of the processes shown in this flowchart are examples, and it is preferable that processes suitable for the embodiment are appropriately adopted as the process contents and order.

  In steps S401 and S402, a request for a power supply plan is made. The reservation processing unit 32 of the in-vehicle device includes information that can identify the vehicle in which the in-vehicle device is mounted (hereinafter, also referred to as “vehicle identification information”), a scheduled arrival time, a stay time after arrival, and a processing standard. A request message for acquiring a power supply plan presented from the power supply facility is transmitted to the server device via the network, including the remaining battery level, vehicle power consumption, and user identifier (step S401). . By obtaining these pieces of information, the server device can predict the remaining battery level when the vehicle arrives at the power supply facility (corresponding to the “remaining battery level upon arrival”) and create an appropriate power supply plan. . The method for predicting the battery level at arrival is substantially the same as that performed by the battery level prediction unit 26 at arrival of the vehicle-mounted device 1, and thus the description thereof is omitted.

  Here, as the estimated arrival time, the estimated arrival time acquired in step S110 can be used. In addition to the information described above, the request message may include other information such as the standard / specification of the power receiving unit provided in the vehicle, the route planned to travel, and the like. When the vehicle information acquisition unit 41 of the server device receives the request message (step S402), the process proceeds to step S403.

In steps S403 to S405, a power supply plan is created and notified to the in-vehicle device. The usage schedule acquisition unit 42 of the server apparatus receives a request message from the in-vehicle device and acquires the usage schedule of the power supply facility, and the power supply plan creation unit 43 determines the power supply plan based on the power supply facility information including the usage schedule. Create (step S403). Specifically, the power supply plan creation unit 43 determines (1) the time required for the remaining battery level to recover from the remaining battery level upon arrival to the required remaining amount after stay or full charge according to the power supply capacity of the power supply facility. (2) The remaining battery level after staying when power is supplied by the power supply facility is calculated based on the information related to the power supply facility (mainly power supply capability), the predicted remaining battery level at arrival and the staying time. (3) Charges are calculated by multiplying the power supply time and the amount of power supplied by the power supply rate, etc. (4) Also, the service point according to the power supply time, power amount, number of times of power supply, etc. Calculation, search based on user identifiers of service points accumulated so far, service point usage guidance, search for discount services for parking fees and power supply fees that can be presented, etc.

  Various information necessary for power supply plan creation such as required remaining amount before arrival, remaining battery amount at arrival, remaining battery amount after stay, required remaining amount after stay, estimated arrival time, mileage, travel time, etc. from in-vehicle device 1 Information necessary for calculation can be obtained and calculated in the server device. A specific method of calculation is substantially the same as that calculated by the in-vehicle device 1.

  The power supply plan may also include reservation availability information. Reservation availability information includes availability information or whether there is an equipment availability at the estimated arrival time based on the reservation information, whether the specifications and specifications of the power supply equipment correspond to the power receiving unit of the onboard vehicle, Is determined by determining whether or not the power transmission capacity is sufficient to receive sufficient power supply during the staying time.

  Then, the power supply plan output unit 44 of the server device creates the time required until the amount of charge desired by the user created in step S403, the remaining battery level when power is supplied by the power supply facility, the charge for power supply, A power supply plan including contents related to various services such as point service, parking fee, power supply fee discount, and the like is transmitted to the vehicle-mounted device via the network (step S404), and the reservation processing unit 32 of the vehicle-mounted device receives this power supply. Obtained by receiving the plan (step S405). Thereafter, the process proceeds to step S406.

  In steps S406 and S407, the power supply plan of the power supply facility is confirmed, and if the reservation is possible, a reservation instruction (selection) by the user is accepted. The reservation processing unit 32 of the in-vehicle device refers to the reservation availability information included in the power supply plan acquired in step S405, and whether or not the power supply facility can be used when the arrival time arrives at the destination. Is determined (step S406).

  As a result of the determination, if the power supply facility is unavailable at the estimated arrival time, the in-vehicle device notifies the user to that effect using the output unit 31 and executes the destination search process again. As a result of the determination, if the power supply facility is available at the estimated arrival time, the in-vehicle device may use the output unit 31 to display the power supply plan and reserve the power supply facility for the user. Notification for prompting confirmation is performed (step S407). Thereafter, the input receiving unit 21 receives a reservation instruction operation or a cancel operation by the user. Thereafter, the process proceeds to step S408.

  In steps S408 to S410, a reservation application for use of the power supply facility, a reservation reception, and a reservation content are stored. Details of the reservation reception and reservation content storage are substantially the same as the processing of steps S208 to S210 shown in FIG. Thereafter, the process proceeds to step S115 shown in FIG. 6, and route guidance is started. In addition, the reservation process of the power supply facility described above may be re-executed (replanned) by changing the conditions in accordance with a change in the traveling state of the vehicle, a change in the route, or a change in the operation schedule.

  According to the power supply system shown in this embodiment, a power supply plan recommended for the power supply facility is created and presented to the vehicle or the user, so that when the reserved vehicle arrives at the power supply facility, another vehicle supplies power. In addition to preventing the situation that the power supply cannot be performed because the equipment is in use, whether or not the power supply equipment can be reserved, the time it takes to complete the charging, the remaining battery level after the stay, the charge, information on the service, etc. This makes it possible to select the most advantageous power supply facility for the user or vehicle.
