ABSTRACT:
A navigation system for motor vehicles determines a plurality of zones for determining the approach of the vehicle to a route intersection. The zones are pie-shaped sectors of circles having the next intersection at its center and having radii that vary with respect to the vehicle velocity. The zones lie along an approach course the vehicle takes in approaching the next intersection. When the vehicle enters any one of the zones thus determined, one of the zones is selected according to the current velocity of the vehicle such that the higher the vehicle velocity is, the larger the radius of the circle corresponding to the selected zone is. The driver is then informed that the vehicle is approaching the intersection and is informed of the direction to take at the intersection.
