ABSTRACT:
A traction control system and method of a four-wheel drive vehicle comprises an engine control apparatus, a brake drive apparatus for automatically and independently applying brake to each of four wheels, wheel speed detecting means, vehicle speed detecting means, steering angle detecting means, yaw rate detecting means, target yaw rate calculating means, yaw rate deviation calculating means, slip amount calculating means for calculating an actual slip amount, reference slip amount storing means for memorizing a reference slip amount, target slip amount determining means for determining a target slip amount based on the reference slip amount, traction control judging means for outputting a traction control signal when a traction control is needed, target braking force calculating means, target engine torque calculating means. When a traction control is needed, the target slip amount determining means determine a target slip amount of a wheel needing the traction control. The target braking force calculating means produce a braking force according to the difference between the target slip amount and the actual slip amount and brake is automatically applied to a wheel requiring the traction control through the brake drive apparatus. At the same time, the target engine torque calculating means produce a signal to the engine control apparatus so as to reduce engine torque.
