  • the switching of the destination determination method in the destination setting unit 22d is not limited to this example.
  • the destination when the vehicle 1d departs, the destination may be set by determining the destination of the vehicle 1d based on the location information of the second user, and the set destination may be notified to the route search unit 23.
  • the destination review condition when the destination review condition is satisfied, the destination may be reset by determining the destination of the vehicle 1d based on the schedule information of the second user, and the reset destination may be notified to the route search unit 23.
  • the destination review condition in this case is, for example, a condition that the location information of the second user cannot be received for a certain period of time or more, but is not limited to this.
  • FIG. 10 is a flowchart showing an example of route determination processing in the information processing unit 2 of this embodiment.
  • FIG. 8 shows an example in which the first user is a child and the second user is the guardian of the first user, but the first and second users are not limited to this, and similar processing is performed even when the second user is other than a guardian.
  • the information processing unit 2d performs steps S1 to S3 in the same manner as in the first embodiment.
  • the information processing unit 2d determines whether or not the destination review condition is satisfied (step S21).
  • the destination setting unit 22d determines whether or not the destination review condition is satisfied.
  • step S21 is repeated. If the destination review condition is met (step S21 Yes), step S11 is performed as in the second embodiment.
  • the information processing unit 2d resets the destination using the location information (step S12a). For example, the destination setting unit 22d resets the destination by determining the guardian's location indicated by the location information stored in the information storage unit 24 as the destination, and notifies the route search unit 23d of the set destination.
  • the information processing unit 2d then redetermines the route using the set destination (step S13a), and ends the route determination process.
  • the route search unit 23d uses the map information stored in the information storage unit 24 to search for a route for the vehicle 1d from the current position of the vehicle 1d indicated by the position information output from the self-location identification unit 5 to the reset destination, and resets the route by determining the route obtained by the search as the route for the vehicle 1.
  • the example shown in FIG. 10 is just one example and is not limited thereto.
  • the destination of vehicle 1d may be redetermined based on the schedule information of the second user.
  • a destination review condition a switching condition for switching from determining the destination of vehicle 1d based on the position information of the second user to determining the destination of vehicle 1d based on the schedule information of the second user
  • the destination of vehicle 1d may be redetermined based on the schedule information of the second user. In this way, the destination determination method may be switched multiple times.
  • the information processing unit 2d shown in FIG. 10 is also realized by a computer system, like the information processing units 2 and 2b in the first embodiment and the information processing unit 2c in the second embodiment.
  • the destination setting unit 22d and the route search unit 23d shown in FIG. 9 are realized by the control unit 101 shown in FIG. 6 executing a program stored in the storage unit 103 shown in FIG. 6.
  • the storage unit 103 is also used to realize the destination setting unit 22d and the route search unit 23d shown in FIG. 10.
  • the vehicle 1d performs the route determination process as in the example shown in FIG. 1, but this is not limited to the above, and the information processing device may perform the route determination process as in the example shown in FIG. 4.
  • the information processing device 7 includes a destination setting unit 22d and a route searching unit 23d instead of the destination setting unit 22 and the route searching unit 23 shown in FIG. 4, and the information acquisition unit 21 acquires schedule information from the information providing device 6 and acquires location information from the user terminal 10.
  • the division of functions between the information processing device and the vehicle is not limited to this example, as in the first embodiment.
  • FIG. 10 shows an example in which vehicle 1d is an autonomous vehicle
  • the configuration and operation of this embodiment can also be applied to manually driven vehicles, similar to the example shown in FIG. 5.
  • information processing unit 2b shown in FIG. 5 includes destination setting unit 22d and route search unit 23d instead of destination setting unit 22 and route search unit 23 shown in FIG. 5, and information acquisition unit 21 acquires schedule information from information providing device 6 and acquires location information from user terminal 10.
  • the information processing unit 2d switches between determining the destination of the vehicle 1d based on the schedule information of the second user and determining the destination of the vehicle 1d based on the location information of the second user.
  • This provides the same effect as in embodiment 1 and allows the destination to be set more appropriately depending on the situation. For example, if the first user riding in the vehicle 1d is a child and the second user is the child's guardian, and after the destination is set based on the guardian's schedule information and the vehicle 1d departs, if the distance between the set destination and the vehicle 1d falls below a threshold, the destination determination method can be switched to adjust the destination according to the guardian's actual location.
