Abstract
A device for the control of the traveling speed of a motor vehicle with a regulating member actuatable by the vehicle driver and giving off an electrical signal, the regulating member being connected with the desired-value input of an electrical controller, the output signal of which acts on an adjustment actuator. The latter is coupled with the element which influences the fuel-air mixture, particularly the throttle valve, and the instantaneous position of the adjustment actuator is transmitted as an electric signal to the actual-value input of the controller. A correction circuit is connected with the actual-value input or the desired-value input of the controller. For the correction of the throttle-valve displacement which is dependent on the regulating member, this circuit produces a signal which is a function of one or more operating parameters which are related to the fuel consumption.
