Abstract
A device for automotive vehicles for both traction control and cruise control is equipped with a common servo motor (13) which, by way of a self-locking gear (14), by way of a switchable friction gear (17) and by way of a linkage (23, 24; 25, 26) acts upon a transmission device interposed into the path of force transmission from an accelerator pedal (1) to the throttle-flap (2) of an internal-combustion engine or to the adjusting lever of the injection pump of a spark-ignition engine. Depending on the switch position of the friction gear (17), the servo motor (13) permits control of either the traction (VR) or the speed (GR). During traction control, a release of the accelerator pedal (1) leads at any time to closing of the throttle-flap (2), while an increase of the pedal force does not have any effect on the position of the throttle-flap. After the activation of cruise control, it is still possible to increase the engine power by further depressing the accelerator pedal (1).
