Abstract
An apparatus for displaying the driving direction and distance coverage of a motor vehicle, wherein a unit distance coverage signal is generated each time the motor vehicle covers a unit distance, a direction signal indicating the present driving direction of the motor vehicle is generated, and the distance and the direction from a starting point to a destination point can be set and the resulting setting signals are generated. The distance coverage for each driving direction of the motor vehicle is accumulated on the basis of the unit distance coverage signals and the direction signals, and from the accumulated values the vector from the starting point to the present position is calculated. The calculated vector and the vector from the starting point to the destination point which is obtained from the setting signals are used to calculate the vector from the present position to the destination. The present driving direction of the motor vehicle is indicated on a first display section in response to the direction signal, and the direction and the distance of the vector from the present position to the destination are displayed on a second display section on the same display panel o…
