ABSTRACT:
A navigation system for motor vehicles determines a pie-shaped sector zone for triggering an indication of a route intersection on a displayed road map. The zone is defined by a pie-shaped sector of a circle having the intersection at its center, and provided with a radius determined with respect to the velocity of the vehicle. When the vehicle enters the zone corresponding to the vehicle's velocity, it is determined that the vehicle is approaching the intersection, and a next intersection to be passed by the vehicle is indicated on the road map. The driver can thus be guided along a predetermined route.
