Abstract (en)

[origin: EP0913565A2] An apparatus for controlling the torque of an engine (2) of a vehicle. The vehicle has a drive train for transmitting power of the engine (2) to a driving wheel (W). An electronic control unit (ECU)(71) corrects the fuel injection amount based on the fluctuation of the engine speed to reduce torsional vibration of the drive train. The engine torque is regulated through the correction of the fuel injection amount to reduce the torsional vibration. The ECU (71) does not correct the fuel injection amount when the engine speed is below a predetermined lower limit. The lower limit is different for each shift position of the transmission (36), so that the torsional vibration is accurately reduced in any shift position. <IMAGE>
