Then, the vehicle position is displayed (step 4).

If the own vehicle position is not on the map in step 2, the process proceeds to step 10, where the current own vehicle position information is input and read into the destination route storage unit 3, and step 1 is executed.
At 1, a map is displayed on the display unit 2 and the process proceeds to step 3.

Next, in step 5, the control unit 5 determines whether or not the own vehicle position and the waypoint are approaching based on the information of the own vehicle position measuring unit 1, and proceeds to step 6; A warning sound is emitted from the speaker 10 and the process proceeds to step 7, where it is determined whether the vehicle is turning right or left based on information from the direction sensor 7 and displayed on the display unit 2.
Proceed to. If the own vehicle position and the waypoint are not approaching, the process proceeds directly to step S8.

In step 8, the control unit 5
Determines whether or not the own vehicle position and the destination are approaching based on information of the own vehicle position measuring unit 1, and if so, emits an alarm sound from the speaker 10 in step 9 and returns to the first step. If not, the process returns to the first step.

In the subroutine shown in FIG. 5 (waypoint change routine), referring to FIG. 1 as well, the process is started, and in step 1, the driver inputs whether or not to delete a waypoint through the input unit 4. If not, the process proceeds to step 6. If the process is to be deleted, the process proceeds to step 2. In step 3, a waypoint to be deleted is selected from the group of waypoints displayed on the display unit 2. In step 3, the waypoint selected by the input unit 4 is selected. Delete a waypoint.
Then, the process proceeds to step 4 to input whether or not to end the waypoint change routine through the input unit 4. If not ended, the process returns to step 1. After the registration in the route storage unit 3, the process returns to the first step.

Also, from step 6, whether or not to add a waypoint is input by the input unit 4, and if not added, the process directly proceeds to the above step 4, and thereafter, the control proceeds in the above order. In step 7, where to add the destination is determined through the input waypoints in the destination route storage unit 3, and in the next step 8, the input unit 4
Then, the waypoint is input, and the process proceeds to the step 4, and thereafter, the control is advanced in the order.

In the subroutine shown in FIG. 6 (routing route selection routine for traffic congestion and construction), referring also to FIG.
First, in step 1, the input unit 4 is used to input a detour position due to traffic congestion, construction, or the like.
Then, it is determined whether or not the planned route and the detour position coincide with each other based on information in the destination route storage unit 3 and the like. If they do not match, the process proceeds to step 8, and if they do, the process proceeds to step 3. , Enter whether or not to make a detour. If not, go to step 8;
To enter whether or not to automatically calculate a detour route.

If the automatic calculation is not performed, the process proceeds to the waypoint change routine of step 9, which is ended, and the process proceeds to step 8. In the case of automatic calculation, step 5
, The control unit calculates the first detour route, and displays the calculation result on the map of the display unit 2 in step 6.

Then, the process proceeds to the next step 7, where it is input whether or not to change the waypoint. If the waypoint is not changed, the process proceeds to a waypoint change routine of step 9, which ends the process, and proceeds to step 8. If it is to be changed, the process proceeds to step 8, a map centering on the own vehicle position is displayed on the display unit 2, and the process returns to the first step.
