Abstract

A device for the control of the traveling speed of a motor vehicle with a regulating unit actuateable by the vehicle driver, particularly a gas pedal, and means for transmission of the movement of the same to an element, particularly the throttle valve, which influences the fuel-air mixture. An electrical controller is provided, the desired value input of which is applied with the output signal of a first electrical position indicator, the latter being coupled with the regulating unit and the actual value input of which is applied with the output signal of a second electrical position indicator, the latter being coupled with the setting member or positioning actuator of an electrical setting or adjusting device, the actuator standing in connection with the element which influences the air-fuel mixture. Upon actuation of the brake or clutch, a coupling device, between a servomotor of the electrical controller and the actuator, is disconnected for a short time.
