Running position indicator apparatus
First Claim
1. A running position indicator apparatus comprising:
- distance detector means for generating a distance signal representing the distance covered by an automobile;
direction detector means for generating a direction signal representing the running direction of the automobile;
destination setting means for generating a destination direction signal representing the angle of the direction from the starting point to the destination and a destination distance signal representing the linear distance from the starting point to the destination;
operation means for calculating the vectorial value from the starting point to the destination in response to said destination direction signal and said destination distance signal, calculating the vectorial value from the starting point to the present position from said distance signal and said direction signal, subtracting the vectorial value from the starting point to the present position from the vectorial value from the starting point to the destination thereby to determine a vectorial value from the present position to the destination, and producing a signal representing the direction from the present position to the destination and a signal representing a linear distance from the present position to the destination; and
indicator means for indicating data on the linear distance from the present position to the destination and data on the direction from the present position to the destination in the same indication section in response to the output signal from said operation means.

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.
