Abstract
A device for the control of the traveling speed of a motor vehicle with a control member actuatable by the vehicle driver, particularly a gas pedal, which is coupled with a first position encoder or indicator, with an electric controller for the transmission of the adjustment movement of the control member to an element, which element influences the fuel-air mixture, particularly to a dosing member of a fuel injection pump, by means of an electric motor, the electric motor being in operative connection with the dosing member and acting against the force of a return spring, which electric motor is supplied with a motor current which current is formed in the controller, as well as with a second position encoder which second position encoder is coupled with the dosing member, the second position encoder being arranged in a feedback circuit with inclusion of the controller. The construction and sizing of the feedback circuit is such that the motor current variation which is formed by the feedback circuit is limited to or by an amount sufficient for the correction of the greatest possible position error of the regulating unit.
