ABSTRACT:
An automobile running position indicator apparatus which comprises a device for generating a unit coverage distance signal each time the automobile has covered a unit distance, a device for generating a direction signal representing the automobile running direction at each time and a device for generating set signals representing the distance and direction from the starting point to the destination. A vectorical length from the starting point to the destination is operated from the set signals. The distance covered by the automobile is accumulated for each direction from the distance signal and the direction signal thereby to calculate a vectorial value length from the starting point to the present position. These vectorial values are used to determine a vectorial length from the present position to the destination, and the resulting vectorial direction and distance are displayed in the same display section.
