ABSTRACT:
A device for the electric control of the speed of an automotive vehicle having a guide signal transmitter developed as settable memory, having a comparison element fed with the guide signal and a vehicle-speed signal, having a control amplifier which is arranged behind the comparison element and gives off a set signal to a setting drive for the displacement of a throttle valve which controls the air-fuel mixture of an internal combustion engine, having a position indicator coupled with the throttle valve apparatus and having a guide signal transmitter developed as settable memory. A comparator for comparing the set signal with a feedback signal given off by the position indicator is provided, the output value of which sets the guide signal transmitter at such a large guide signal that the position of the throttle valve at an end of the setting process, which has been determined during the setting by a driver, is established by the set signal.
