Adaptive distance and speed control system for vehicle, limits desired speed obtained by control function to maximal speed dependent on relative speed

摘要

A sensor (14), e.g. a radar, measures a distance (d) and a relative speed (Vr) of the target object in front of the vehicle. An input device (18) receives a set speed value (Vset) and a control device (10) with three functions. A speed control function adjusts a speed to the set speed, a distance control function adjusts the distance to the target object to the set distance, and a limiting function limits a desired speed (Vsoll) to the maximal speed (Vlim) dependent on the relative speed (Vr)
