ABSTRACT:
A torque-biasing system (10) including a torque-biasing device (12) and a control unit (14) for use in a vehicle (16). The torque-biasing system is preferably installed and used in a vehicle having a first wheel (18) with a first rotational speed and a second wheel (20) with a second rotational speed, and an engine (22) with a torque output. The control unit (14) calculates an error value based on a different between the first rotational speed and second rotational speed and derives a control signal based upon proportional and integral terms of the error value with a forgetting factor. The control unit then sensor the control signal to the torque-biasing device (12).
