Then, the route search unit 231 sets a route candidate from the departure point to the destination as a provisional route. Note that the route candidates from the departure point to the destination may be determined based on traffic information acquired by the traffic information acquisition unit 237, which will be described later. For example, if the traffic information is congestion information indicating the state of congestion in the area where the vehicle 300 travels, or traffic congestion statistical information, the route candidate is a route that avoids the congestion in the area where the vehicle 300 travels. may

Further, when the traffic information is road information, the route candidate may be a route that avoids roads that are closed due to factors such as road construction or traffic accidents. If the traffic information is weather information, the route candidate may be a route that avoids locations where road surface conditions are estimated to be poor (locations with torrential rain or snowfall).

The route search unit 231 may calculate route candidates from the departure point to the destination using the Dijkstra algorithm as an algorithm in graph theory for efficiently solving the shortest path problem. The route search unit 231 may also calculate route candidates from the departure point to the destination using various algorithms for solving the shortest route problem, such as the Bellman-Ford method and the Warshall-Floyd method. In addition, the route search unit 231 may use the Ising model or annealing to calculate route candidates from the departure point to the destination.

The route search unit 231 acquires the specified arrival time to the destination included in the request, and based on the specified arrival time and the time required for the vehicle 300 to pass through the route candidates and reach the destination, , the departure time may be calculated. The calculated departure time may be output via communication section 210 . Here, the output departure time may be presented to the user via the display unit 160 of the terminal 100, for example.

Note that the route searching unit 231 may calculate the charging time of the vehicle 300 at the charging spot extracted by the charging spot extracting unit 235, which will be described later. In this case, the route search unit 231 adds the travel time required to travel the route candidate from the departure point to the destination and the charging time, and calculates It is also possible to calculate the time required.

In addition, when the determination unit 239, which will be described later, determines that the vehicle 300 cannot reach the destination by traveling the temporary route, the route search unit 231 selects route candidates from the departure point to the destination, A route candidate passing through the ground may be reset as a tentative route. At the time of resetting, route candidates from the departure point to the destination may be determined based on traffic information acquired by the traffic information acquisition unit 237, which will be described later. The waypoint may be a charging spot extracted by the charging spot extraction unit 235, which will be described later.

Further, when the determination unit 239, which will be described later, determines that the vehicle 300 can travel the temporary route and reach the destination, the route search unit 231 selects the temporary route as a driving route to be used for route guidance of the vehicle 300. It may be set. The travel route set by the route search unit 231 is output to the outside of the server 200 and displayed on the terminal 100 or used for travel by the vehicle 300, for example.

When vehicle 300 passes through a charging spot while vehicle 300 passes through the provisional route and is scheduled to be charged at the charging spot, the remaining charge amount of vehicle 300 is set in advance at the charging spot. The power consumption calculation unit 233 may calculate the transition of the remaining charge of the vehicle 300 as a value larger than the threshold.

In addition, the power consumption calculation unit 233 may estimate whether or not there is a point where the remaining charge of the vehicle 300 is equal to or less than a predetermined threshold while the vehicle 300 travels on the provisional route. If the point where the remaining charge of vehicle 300 is equal to or less than a predetermined threshold is not a charging spot, it can be determined that vehicle 300 cannot travel ahead of that point. Therefore, if there is a point other than the charging spot on the temporary route where the remaining charge of the vehicle 300 is equal to or less than the predetermined threshold value, the power consumption calculation unit 233 determines that the vehicle 300 may not calculate the transition of the remaining charge.

The determining unit 239 (determining means) determines whether or not the vehicle 300 can travel the temporary route and reach the destination based on the remaining charge of the vehicle 300 . More specifically, when the power consumption calculation unit 233 estimates that there is a point where the remaining charge of the vehicle 300 is equal to or less than a predetermined threshold while the vehicle 300 is traveling along the provisional route, the determination unit 239 It is determined that the vehicle 300 cannot reach the destination by traveling the temporary route.

On the other hand, when the power consumption calculating unit 233 estimates that there is no point where the remaining charge of the vehicle 300 is equal to or less than the predetermined threshold value while the vehicle 300 travels along the provisional route, the determination unit 239 determines that the vehicle 300 It is determined that the destination can be reached by traveling the temporary route.

The charging spot extracting unit 235 (charging spot extracting means) adds charging spots in the area including the departure point and the destination as transit points. More specifically, the charging spots located on the candidate route from the departure point to the destination or near the candidate route are extracted. For example, the charging spot extraction unit 235 extracts charging spots within a reachable range of the vehicle 300 from the starting point based on the remaining charge of the vehicle 300 . Then, the charging spot extraction unit 235 sets the extracted charging spot as a waypoint to be used when resetting the provisional route in the route searching unit 231 .

The charging spot extraction unit 235 may add one or more charging spots as waypoints. For example, as a result of setting one or more charging spots as waypoints, the provisional route set by the route search unit 231 may be a candidate route that passes through one or more charging spots. .
