Abstract

Abstract A device for the transmission of the position of a control element, particularly a gas pedal, (which control element is actuatable by the vehicle driver and controls the traveling speed of a motor vehicle, the gas pedal being connected with an electrical position encoder), to an actuator via electrical transmission means, the actuator being coupled with a regulating member, particularly a throttle valve, which member controls the fuel-air mixture of an internal combustion engine. A pedal contact is coupled with the control element, a regulating member contact is coupled with the regulating member and the pedal contact and the regulating member contact are arranged in a logic circuit arrangement (the logic circuit arrangement being connected with a unit that brings about a rotational speed reduction of the internal combustion engine), such that the rotational speed is reduced with a non-actuated control element, but with a simultaneous position of the member that controls the fuel-air mixture in the gas position.
