Abstract
A device for controlling the engine drive power for automotive vehicles with traction control. A hydraulically actuatable control apparatus (1, 1') is inserted between the drive control pedal (7, 7') and the control member (10, 10') of the vehicle engine. The housing (2, 27) of the control apparatus (1, 1') is stationary and accommodates a piston (3, 30) which is axially slideably by the introduction of auxiliary pressure. The piston is coupled to the drive control pedal (7, 7'), on the one hand, and to the control member (10, 10'), on the other hand. A biased non-return valve (21, 45) which opens by a pedal-side tappet (18, 38) in the event of reduction of the pedal force (F) causes resetting of the control member (10, 10') when the pedal (7, 7') is released. An increase of the pedal force (F) during traction control will not result in a change in the position of the control member.
