Abstract
A torque-biasing system (10) includes a torque-biasing device (12) and a control unit (14) for use in a motor vehicle. The torque-biasing system is preferably installed in a vehicle having a first front wheel (18) with a first rotational speed and second wheel (20) with a rear rotational speed and an engine (22) with a torque output. The control unit (14) functions to determined when and how to bias the torque output of the front and rear wheels, and to control the torque-biasing device (12) based on this determination.
