By the way, the % mold of the present invention is characterized in that when the inside of the vehicle reaches a certain range including a predetermined target point, the direction in which the vehicle should proceed next is indicated by display, voice, etc. at this point. Therefore, in this example, '4
As shown in FIG. 2, if two L cars travel from the starting point 8 to the destination Dt via the target points Vl, Vx, Vs, then the starting point 8, the target points Vx, Vs, Vs, and Position information on the destination display m1iil is given using the keyboard 26. This position information is set according to the coordinates corresponding to the display image mK. Furthermore, areas P1, Ps, and Ps are set for starting display of the target points Vl, Vs, and VsKti in the direction of movement of the vehicle.

These areas Ps, Ps, Ps have a range of, for example, a medium diameter of 13011& in terms of actual distance. The position data of these areas Pt, Ps, Ps is recorded on a cassette tape, and when the displayed map is played back, the position data is read at the same time and stored in the RAM 16, and the vehicle's travel trajectory is recorded in these O areas PI, Ps, Ps. When Σ is displayed in Ps, the microcomputer 14 performs calculations to display the direction in which the car should proceed next.

Next, a method for detecting the traveling direction of the vehicle will be explained. The method for detecting the direction of movement of a vehicle at a target point is as shown in sq, when the traveling trajectory of the vehicle is displayed within the area Ps of the target point Vs. The traveling direction of the vehicle is calculated depending on whether it is included. That is, the traveling direction of the vehicle is calculated by the process 11 shown in the flowchart of FIG. First, when the vehicle travels along the route according to the travel route map to the destination, in step 100 it is determined whether the travel trajectory at the current location of the vehicle is displayed within the scope of area P road at the target point 4. A judgment is made. NO in step 100
