Abstract
A vehicle traction controller controls vehicle traction and directional stability by determining the rotational velocity of the vehicle. The rotational velocity of the vehicle is measured and compared to a predefined range. If the rotational velocity is outside of the predefined range, then a wheel torque value, which is indicative of a braking force to be applied independently of driver initated braking, is generated for each wheel which is on a side of the vehicle as determined by the rotational velocity. The wheel torque value is compared to a range of values, which is based on road surface friction, and altered if the wheel torque value is outside of the range of values. Wheel spin and skid control is employed to reduce wheel spin and skid.
