Abstract
An installation for the control of a motor vehicle drive unit which includes a reciprocating piston engine, a hydraulically actuated clutch and a transmission. A drive pedal pick-up controls the throttle valve and therewith the engine torque by way of a first characteristic curve converter while it applies a signal by way of a second characteristic curve converter a to a control apparatus, to which is also fed at the same time the engine rotational speed n. The control apparatus forms the product a.multidot.n.sup.2 and applies the same as output signal to the electromagnetic actuating mechanism of the hydraulic clutch so that the pressure thereof and also the torque in the clutch is proportional to the product a.multidot.n.sup.2.
