The server device 13 includes a processing computer 41, a storage device 42, and a communication device 43. The processing computer 41 includes an arithmetic processing unit such as a microcomputer in which various control programs are mounted, and exhibits various functions by executing the control program. Specifically, the processing computer 41 includes an actionable range acquisition unit 51, an extraction unit 52, a route acquisition unit 53, a selection unit 54, a priority setting unit 55, and the like as functional units.

[Function and processing procedure of processing computer 41]
Hereinafter, details of each functional unit in the processing computer 41 of the server apparatus 13 will be described with reference to the flowchart in FIG.
When the processing computer 41 of the server device 13 receives various types of information including a destination information provision request instruction from the in-vehicle device 12 via the communication device 43 (step S1 in FIG. 4), the function of the actionable range acquisition unit 51 A range in which the vehicle 11 can act is acquired (step S2). Specifically, the actionable range acquisition unit 51 obtains the actionable range of the vehicle 11 from the position information of the own vehicle, the remaining battery information, and the electricity cost information transmitted from the in-vehicle device 12. First, the actionable range acquisition unit 51 obtains the maximum distance that the vehicle 11 can travel from the battery remaining amount information and the power consumption information according to the battery remaining amount. Next, a range in which the vehicle 11 can actually act is estimated based on the maximum travel distance. In an actual road, there are various factors that cause the electric cost to deteriorate, such as intersections, railroad crossings, slopes, curves, and sudden acceleration / deceleration, with the vehicle 11 turning left and right before reaching the destination. Further, it may be necessary to consider not only traveling to the destination but also returning to the original position (current position). Therefore, as shown in FIG. 1, the actionable range acquisition unit 51 sets, as the actionable range, a circular range having a radius R that is shorter than the maximum travel distance with the current position of the vehicle 11 as the center.

  The radius R of the actionable range is a distance that can be traveled with a sufficient margin in consideration of various factors as described above, for example, 1/3 to 1/4 of the maximum travel distance. The distance can be about. For example, when the maximum travel distance is about 100 km, the range within a radius of about 25 to 35 km from the current position of the vehicle 11 can be set as the actionable range. Further, the actionable range is not limited to the circular range, and may be a square range with the current position of the vehicle 11 as the center.

  Also, the actionable range can be obtained as follows. In other words, power consumption necessary for traveling is defined in advance for each road (link), and the roads connected to the current location are selected, and at the same time, the power consumption defined for each road is integrated, When this integrated value reaches the remaining battery level, the road is set as the boundary of the actionable range. This process is performed brute force on all roads connected to the current location. With this method, although the calculation load slightly increases, a more accurate actionable range according to the remaining battery capacity can be obtained.

  The extraction unit 52 in the processing computer 41 extracts a facility (destination) that matches the action purpose transmitted from the in-vehicle device 12 from the actionable range (step S3). For example, as shown in FIG. 1, facilities A to D within the actionable range are extracted as destinations, and facilities E to G outside the actionable range are excluded from the destinations. For example, if the action purpose is “shopping” − “food”, a supermarket or a convenience store is extracted from the actionable range. In this way, by extracting destinations that match the action purpose within the actionable range, it is possible to narrow down the destinations that can be reached to some extent by the current remaining battery level without searching for a route to the destination. . Therefore, it is possible to reduce the calculation load for acquiring the route to the destination.

  As a result of the destination extraction process, if there is no corresponding destination, the server device 13 transmits information indicating that there is no destination to the in-vehicle device 12 (step S11 in FIG. 4). Exit.

The route acquisition unit 53 in the processing computer 41 performs processing for acquiring a route to the destination extracted by the extraction unit 52. Specifically, first, the vehicle type of the vehicle 11 is determined based on the information transmitted from the in-vehicle device 12 (step S5 in FIG. 4). Then, the route acquisition unit 53 searches for a route to each destination according to the type of the vehicle 11 (step S6).
For example, when the type of the vehicle 11 is an electric vehicle that can travel on an expressway, the route is searched including the passage of the expressway in the route to the destination. Conversely, when the type of vehicle 11 is an electric motorcycle or personal mobility that cannot travel on the highway, the route is searched after excluding the highway on the route to the destination.

  The route search can be performed by acquiring a route that minimizes the link cost from the current position to the destination by a conventionally known route search logic, for example, the Dijkstra method. The route acquired by the route acquisition unit 53 is not limited to the one that prioritizes the distance to the destination, but may be one that prioritizes the arrival time and one that prioritizes the power consumption.

  The selection unit 54 in the processing computer 41 selects an actually-achievable destination from the extracted destinations (step S7 in FIG. 4). Specifically, the estimated arrival time when the vehicle 11 travels from the current position to the destination through the searched route is obtained, and the estimated arrival time is calculated from the sales information of the destination read from the storage device 42. It is determined whether or not it is inside. When the estimated arrival time is within business hours, the selection unit 54 selects the facility as a destination, and when the estimated arrival time is outside business hours, the selection unit 54 excludes the facility from the destination. Process. In the example shown in FIG. 1, the facilities A to C are selected as destinations because the estimated arrival times are within business hours, and the facilities D are excluded from the destinations because the estimated arrival times are outside business hours. Is done. As a result of such destination selection processing, if there is no destination that can be reached within business hours, the processing computer 41 transmits information indicating that there is no destination to the in-vehicle device 12 (see FIG. 4, step S11), the process is terminated.

  When it is determined that the destination exists as a result of the destination selection process, the priority setting unit 55 in the processing computer 41 sets the priority for the destination according to a predetermined condition (step S9). Specifically, as shown in FIG. 5, the priority setting unit 55 first sets the remaining battery level at the time of arrival for all destinations selected by the selection unit 54 as an initial condition (first condition). The amount is estimated, and the priority is set such that the higher the battery remaining amount, the higher the priority (step S21). For example, if there is a factor that increases power consumption such as an uphill on the route to the destination, the remaining battery level is considered to decrease even if the distance to the destination is short. Set a lower priority for such destinations. On the contrary, when there is a downhill in the route, the remaining battery level is recovered by the regenerative power of the electric motor, and the remaining battery level at the time of arrival is increased. Set a high priority for the ground. Through the above processing, the priority setting unit 55 sets initial priority values for all destinations. By setting the priority based on the remaining battery level when reaching the destination in this way, it is possible to travel to the destination with less power consumption when a destination with a high priority is selected. Become.

  The priority setting unit 55 has a function of adjusting the priority based on other conditions. Specifically, the priority setting unit 55 determines, as the second condition, whether or not the destination has a secondary battery charging facility, or whether or not the charging facility exists on the route to the destination. Adjust priority. The priority setting unit 55 determines whether or not there is a charging facility at the destination or the route (step S22 in FIG. 5). If there is a charging facility, the priority setting unit 55 increases the priority (or there is no charging facility). In this case, a process for lowering the priority is performed (step S23). By adjusting the priority according to the presence or absence of the charging equipment in this way, when a destination with a high priority is selected, there is a high possibility that the charging equipment exists at the destination or route, It is possible to more reliably avoid power shortage when traveling to the destination.

  The first and second conditions described above are conditions relating to the remaining amount of the battery, and are conditions of extremely high importance for the vehicle 11 that travels with the power of the battery and has a short cruising distance. Therefore, the priority setting unit 55 of the present embodiment sets the priority in consideration of these first and second conditions. In addition, since the absolute number of public charging facilities for electric vehicles is small at present, it is very useful to include the presence / absence of charging facilities as a condition for setting priority for route search.

  As the third condition, the priority setting unit 55 adjusts the priority according to the congestion situation of the facility at the expected arrival time at the destination. The storage device 42 stores information such as a busy time slot or an empty time slot as facility information. The priority setting unit 55 determines whether or not the facility is congested at the expected arrival time at the destination (step S24 in FIG. 5), and when it is congested, a process for lowering the priority (or congestion) If not, a process for increasing the priority is performed (step S25). By adjusting the priority according to the congestion situation, when a destination with a high priority is selected, the purpose can be achieved smoothly and efficiently without being involved in the congestion.

  The priority setting unit 55 adjusts the priority according to the use frequency of the destination as the fourth condition. The storage device 42 stores information on destinations that have been guided in the past and information on the travel trajectory of the vehicle 11, and the frequency of use of the facility, for example, the number of times of use in a certain past period can be obtained from the information. The priority setting unit 55 determines whether or not the number of uses is greater than or equal to a predetermined number (step S26). If the number of uses is greater than or equal to the predetermined number, the priority setting unit 55 increases the priority (or the destination where the number of uses is less than the predetermined number). Process for lowering the priority). In this way, by adjusting the priority according to the use frequency of the destination, the higher the priority, the higher the possibility that the user's preference is more suitable.

  The above first to fourth conditions are examples, and in addition to or instead of them, the priority may be set based on other conditions. Moreover, the order of the first to fourth condition determinations can be changed as appropriate. As other conditions, for example, the length of the period from the last use of the facility to the present, the use fee of the facility, the presence or absence of a parking lot, the parking fee, etc. can be adopted.

The processing computer 41 determines whether or not priority adjustment has been performed for all destinations (step S28 in FIG. 5), and if not, the processing is returned to step S22 and performed. If so, the process proceeds to step S10 (see FIG. 4).
Then, the processing computer 41 transmits destination information (location, route, priority, etc.) to the in-vehicle device 12 via the communication device 43, and ends the processing.

  The in-vehicle device 12 displays the received destination information on the display 27 in a state where it can be selected via the input device 29. When the user's desired destination is selected from the destinations displayed on the display 27, the in-vehicle computer 21 displays the route to the destination on the map and starts guidance.

  As described above, according to the destination information providing system of the present embodiment, the processing computer 41 of the server device 13 can act on the vehicle 11 based on the current position of the vehicle 11, the power consumption, and the remaining amount of the secondary battery. A range is acquired, and a destination corresponding to a desired action purpose is extracted from the acquired actionable range. Therefore, the vehicle 11 can reliably reach the destination within the actionable range without causing the battery power shortage.

With respect to the present invention, it should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is not meant to be described above, but is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
In the present embodiment, the processing computer 41 of the server device 13 performs processing such as acquisition of an actionable range of the vehicle 11, extraction of a destination, acquisition of a route, selection of a destination, setting of priority, etc. All or part of these processes may be performed by the in-vehicle computer 21 of the in-vehicle device 12. However, in this case, the computation load on the in-vehicle computer 21 increases and the power consumption of the battery also increases, which may adversely affect the cruising distance. Therefore, by causing the server device 13 outside the in-vehicle device 12 to perform a calculation with a large load as in the present embodiment, it is possible to suppress the power consumption of the battery and secure the cruising distance as much as possible.

The in-vehicle device 12 may be a device installed on the vehicle 11, but may be a mobile terminal such as a smartphone or a tablet terminal. In this case, some of the functions shown in FIG. 3, for example, the function of acquiring the vehicle speed and the function of acquiring the remaining battery level and power consumption are omitted. Therefore, the battery remaining amount may be read from the meter or the like of the vehicle 11 so that the user directly inputs it to the portable terminal, and the power consumption is calculated by the vehicle 11 or calculated by the user. May be directly input to the mobile terminal.
Moreover, the mobile body of the present invention is not necessarily a vehicle (a vehicle that travels by wheels).
