ABSTRACT:
The present invention relates to a digital system for maintaining the speed of a motor vehicle at a preselected speed. The desired speed of the vehicle is set into a digital memory bank and the instantaneous actual speed of the vehicle is determined by a digital readout. The desired vehicle speed and the actual speed of the vehicle are compared to produce a digital error signal which is used to control the throttle setting of the vehicle to cause the actual speed of the vehicle to equal the desired speed.
