Traction Control System (TCS) otherwise called as Acceleration Slip Regulation (ASR) helps in limiting the tire slip on a slippery surface while accelerating. Earlier, drivers used the gas pedal when they drive on a slippery surface. But modern vehicles come with electronic controls for drivers to limit the delivery of power, eliminate wheel slip and aid the driver to accelerate with control. Traction control systems work with the help of speed sensors that are used by the ABS. Based on the differences in the rotational speed, these sensors decide whether any of the wheels has lost traction. If the TCS decides that one wheel is spinning more quickly than the rest, then it uses the brake to control the speed of the particular wheel and brings down the chances of wheel slippery. In most of the cases, the wheel braking of a particular wheel will control the wheel slip but in some cases, TCS also restricts the power supplied by the engine to the slipping wheels. However, traction control cannot be used in the prevention of vehicle getting struck in snow. The two main functions of traction control system is to achieve acceleration performance and directional stability in adverse road conditions where the driver may not able to have control over the car. While accelerating if the tire loses traction then ABS can detect the same, take action for the same and regain traction. Mostly the car manufacturer offer this as a separate option though it shares major components with ABS. The advanced version of TCS can control even throttle levels as well as the brakes.
