ABSTRACT:
Drive unit for motor vehicles, comprising an internal combustion engine (2), an accelerator pedal and an electronic engine control unit (15) arranged for controlling engine torque and r.p.m. The accelerator pedal is electrically connected to the engine control unit. During acceleration, the engine control unit controls the torque as a function of engine speed for various accelerator pedal positions, as determined by a first computer matrix stored in the control unit, which provides a predetermined additional torque when there is a certain reduction in engine speed. After constant or practically constant vehicle velocity has been achieved at a constant accelerator pedal position, the engine control unit controls the torque as a function of engine speed along a second stored computer matrix, which provides a predetermined greater additional torque when there is said predetermined reduction of the engine speed.
