The traction control system prevents the wheel slipping, which occurs due to the loss of traction during acceleration. This usually happens on a slippery surface, such as snow or wet road, where the wheels are not able to generate enough traction to move the vehicle. The anti-lock brake system (ABS) also prevents the sliding of the vehicle due to the losing clutch with the road. The main difference between the control systems of the ABS and the traction control system is that the ABS stops the wheel from the loss of traction during braking, while the traction control stops the wheel from the slip, when the car accelerates. Traction control systems are often called other names (for example, the system of anti -slip regulation or control of a stable position); However, traction control is not the same as an electronic system for controlling stability or active control of deviation from the course.
Traction control system
Traction control systems use the speed sensors of the wheel rotation to determine the speed at which the drive wheels rotate. They discover any sliding that is happening between the bus and the road. If the slip is detected, the system slows down the wheel using the brakes or reducing the torque of this wheel, until it is able to produce the required amount of adhesion to move the vehicle. In cars with a standard differential, using the brake to a slipping wheel, the amount of torque on the opposite wheel increases, which may have the best adhesion to the road. If both driven wheels lose the clutch with the road, the traction control system, as a rule, slows down both wheels the same until they restore the clutch with the road.
Some vehicles provide the opportunity to disable the traction control system.
