Abstract

A device for the control of the traveling speed of a motor vehicle with a regulating member actuatable by the vehicle driver, the gas pedal emitting an electrical signal, the gas pedal being connected with the desired value input of an electrical controller, the output signal of which acts on a positioning actuator, the latter being coupled with the element, particularly the throttle valve, which influences the fuel-air mixture, the instantaneous setting position of the positioning actuator being transmitted as an electric signal to the actual value input of the controller. The actual value input or the desired value input of the controller is driven by a circuit which produces a signal for influencing the position of the throttle valve, which signal is dependent on at least one factor to be monitored.
