Converter for cruise control system

摘要

A converter for use with a constant speed vehicle cruise control system including a speedometer for generating a self speed signal representative of the self speed of the vehicle and a speed adjustment control responsively coupled to the speedometer for maintaining the self speed of the vehicle at a preset speed. The converter adapts the control system to a constant distance system, and comprises a rangefinder for generating a distance signal corresponding to the distance of the vehicle from a front vehicle, and a distance-dependent speed adjustment device coupled to the rangefinder and to the speedometer for generating a synthetic-speed signal corresponding to the set speed required for maintaining a predetermined distance between the two vehicles. A selector switch allows either the self speed or synthetic-speed signals to be connected to the speedometer of the cruise control system.
