Abstract: Disclosed is a system for regulation of torque demanded from a prime mover of a vehicle, which prime mover responds to the torque demanded by delivering a dynamic torque. This dynamic torque is related by a gear ratio to a dynamic wheel torque which a power train comprising the prime mover imparts to at least one tractive wheel of the vehicle. The system regulates the torque demanded in such a way that a difference between the torque demanded and the dynamic torque is actively limited by employing feedback of the dynamic torque at an earlier time. The torque demanded at a time (t) for the regulation is limited to a maximum value which exceeds the dynamic torque at an earlier time by an offset value. The torque demanded is continuously varied according to the dynamic torque, so that power train oscillations in the vehicle are reduced in number and/or magnitude.
