ABSTRACT:
A device for the control of the traveling speed of a motor vehicle with a regulating unit which is actuatable by the vehicle driver, particularly with a gas pedal, with electrical means for the transmission of the movement of the same to an element which influences the fuel-air mixture, particularly a throttle valve, with an electrical controller, the element which influences the fuel-air mixture being in operative connection with the output of the electrical controller, and with at least one comparator, one of the inputs of the comparator being applied with a voltage which is proportional to the rotational speed of the motor and its other input being applied with an adjustable constant voltage value for the rotational speed limitation. As a controller a PI controller is connected in parallel with a P-controller of great amplification.
