[0086] Figure 9 and Figure 10 Shows the second embodiment. The second embodiment differs from the above-mentioned embodiments in that, for example, an empirical route that has been traveled in the past is partially used, and a route that has not been traveled in the past is partially searched for a route that matches the outgoing route and the returning route. The same or similar symbols are assigned to the same or similar parts as those in the above-mentioned embodiment, and description thereof will be omitted, and the different parts will be mainly described below.
[0087] Figure 9 An explanatory diagram showing a case in which a route that has been traveled in the past is partially used, and a route that has not been traveled in the past is partially searched for a route that matches the outgoing route and the return route.
[0088] According to the above-described embodiment, regardless of whether the vehicle has been used in the past, a round-trip route that satisf...

[0094] Figure 11 The route search system of the third embodiment is shown. The third embodiment differs from the above-described embodiments in that, for example, a route search device is provided outside the mobile body, and route search information is transmitted from the route search device to a mobility support terminal device mounted on a vehicle. Parts having the same or similar functions as those in the above-mentioned embodiment are assigned the same or similar symbols and their descriptions are omitted, and the different parts will be mainly described below.
[0095] Figure 11 It is an explanatory drawing showing this embodiment. In the above-described embodiments, an example in which the route search device A is mounted in the navigation device 1 was shown. In the present embodiment, an example is shown in which the route search process is executed by the external center device 20 and the route calculation result is transmitted to the movement support terminal d...
