When the route search switch of the input device 6 is operated, the controller 1 starts this route search process. In step 1, the current position of the vehicle is detected by satellite navigation or self-contained navigation. When the occupant inputs the current position using the input device 6, the current position is used. In the following step 2, the destination set by the passenger is read by the input device 6. In step 3, the optimum route from the current position to the destination is searched using the road map data in the storage device 5.
At this time, the time regulation section (road section where the passage time is regulated) is also targeted for route search. Although various methods have been proposed for the route search method, the description thereof is omitted because it is not directly related to the present invention. In step 4, it is confirmed whether or not there is a time regulation section on the optimum route of the search result. If there is no time-restricted section, the process proceeds to step 6, where a road map around the current position, the optimum route and the current position are displayed on the display 7 to guide the occupant.

み、経路誘導を続ける。When there is a time regulation section on the searched optimum route, the first node of the regulation section is stored in step 5, and then route guidance is started in step 7. In step 8,
It is confirmed whether or not the first node in the restricted section has approached a predetermined distance, and when the distance to the node becomes equal to or less than the predetermined distance, the process proceeds to step 9. It is desirable that the predetermined distance is an appropriate distance that allows the vehicle to travel to a road that bypasses the time-restricted section before it detours, and it is desirable to change the distance according to the type of the road. In step 9, it is confirmed whether or not there is a predetermined time or more before the regulation start time of the time regulation section. If the time is more than the predetermined time, it is determined that the time regulation section can be passed, and the process proceeds to step 10. This predetermined time is equal to or longer than the time required to travel the predetermined distance described above.
The traffic congestion information of the road may be obtained by a road traffic information communication system such as ATIS or VICS and the predetermined time may be changed in consideration of the traffic congestion information in the speed regulation value of the traveling road. On the other hand, when the regulation start time does not exceed the predetermined time and the regulation section cannot be reached outside the regulation time, the time regulation section is excluded in step 12 and the optimum route from the current position to the destination is searched again. . Step 10
Check whether there is a next time regulation section. If there is a next time regulation section, return to step 5 and repeat the above processing. If there is no next time regulation section, proceed to step 11 to guide the route. Continue.
