More specifically, the program P2 of the second determination unit 26 reflects the preference of the passenger P in the driving route according to the preference of the driver D tentatively determined above.

As a result, a driving route (for example, a route with a small number of stops and a scenic view) that matches the preference of the driver D (for example, a route with a small number of stops) and the preference of the passenger P (for example, a route with a good view) A good route) is extracted and selected as an operation route (final decision).

Then, the determined driving route is input to the display unit 27 as route data and displayed on the display unit 27 so that the driver D can be guided.

Further, in the above-mentioned route setting system 1, a dynamic map system can be adopted. If a dynamic map system is adopted, for example, road congestion information, signal information, weather information, etc. are updated in real time, and the preference of driver D (for example, a route with a small number of stops) and the preference of passenger P (for example). , The driving route can be appropriately modified (rerouted) so as to match the scenic route).

4. Action / Effect The above-mentioned route setting system 1 has a first determination unit 24 that provisionally determines a driving route according to the preference of the driver D, and a second determination unit 24 for reflecting the preference of the passenger P on the driving route. Since the determination unit 26 is provided, not only the preference of the driver D but also the preference of the passenger P can be reflected in the driving route.

5. Another Embodiment As shown in FIG. 2, the route setting system 1 can further include a selection unit 29.

As a result, the preference data of the passenger P held in the second input unit 25 is not input to the program P2 of the second determination unit 26. As a result, the preference of the passenger P is not reflected in the driving route. That is, the driving route reflecting only the preference of the driver D is displayed on the display unit 27.

In such a route setting system 1, the driver D can select whether or not the preference of the passenger P input to the second input unit 25 is reflected in the driving route in the selection unit 29. Therefore, the route can be set with priority given to the preference of the driver D over the preference of the passenger P, and the driving comfort and the driving safety can be improved.

In the above embodiment, the driver D's preference is input to the first input unit 23, and the driving route is tentatively determined by the first determination unit 24, but the driver D is tentatively determined by the first input unit 23. It is not necessary to input the preference of. In such a case, the current location of the automobile 10, the destination of the automobile 10, and the preference of the passenger P are input to the second determination unit 26, respectively, and the program P2 of the second determination unit 26 is the current location of the automobile 10. The driving route can be determined based on the destination of the automobile 10 and the preference of the passenger P.
