Patent ID: 7047124

Claim:
Drive unit for a motor vehicle, comprising an internal combustion engine ( 2 ), a manually adjustable throttle control ( 16 ) and an electronic engine control unit ( 19 ) for controlling the engine torque and engine speed, and to which the throttle control is electrically connected, a first computer matrix plotting engine torque as a function of engine speed for various throttle control positions being stored in said engine control unit and having in a diagram a first slope for the curves (A) for the throttle control positions, characterized in that a second computer matrix plotting engine torque as a function of engine speed for various throttle control positions is stored in the engine control unit ( 15 ), that the curves (G) for the throttle control positions in the diagram of the second matrix have a steeper slope than the curves (A) in the diagram of the first matrix, and in that the engine control unit is disposed, at a setting of the throttle control ( 16 ) giving rise to an acceleration exceeding a predetermined minimum acceleration, to control the engine torque and engine speed along the curves (A) in the first matrix diagram and, upon a signal indicating a drop below said minimum acceleration, to control the engine torque and engine speed along the curves in the second matrix diagram (G), so that for a certain change in engine speed, a greater change in torque will be provided than when controlling along the curves in the first matrix diagram.
