ABSTRACT:
A device for controlling at least one variable influencing the drive torque of a motor vehicle uses the difference between acceleration of a driven wheel and the vehicle longitudinal acceleration as a control variable. The exceeding of a slip threshold within specific time windows after the driven wheel speed has fallen below the threshold or after increasing the drive torque is used as a check for the correct dosage of drive torque and the slip threshold itself is adjusted depending on the vehicle longitudinal acceleration. This permits an optimum propulsive acceleration and the control device to adapt to changing road conditions.
