ABSTRACT:
A device for regulating the traveling speed of a motor vehicle, compares a signal proportional to the actual speed of the vehicle with a signal proportional to the set or desired speed, and superposes on one or both of the signals a periodic signal having at least one periodically recurring section of non-linear characteristic, to obtain a control signal whose amplitude is modulated as a function of the magnitude of deviation between the actual speed signal and the set speed signal, and the control signal is transmitted to a control stage influencing the fuel-air mixture supplied to the engine of the vehicle.
