Brakes and Traction control

Brakes and Traction control or traction control system (TCS), in German known as Antriebsschlupfregelung (ASR), is typically (but not necessarily) a secondary function of the electronic stability control (ESC) on production motor vehicles, designed to prevent loss of traction of driven road wheels. TCS is activated when throttle input and engine torque are mismatched to road surface conditions.

The intervention consists of one or more of the following: Typically, traction control systems share the electrohydraulic brake actuator (which does not use the conventional master cylinder and servo) and wheel speed sensors with ABS.
