Anti-Lock & Traction Control: Purpose

Fig 1: ABS/TCS Communication Diagram

The ABS (anti-lock brake system)/TCS (traction control system) allows for mutual communication between the following two systems.

1. The Anti-Lock Brake System (ABS) consists of electronic and hydraulic components. It allows for control of braking force so locking of the wheels can be avoided.

   The ABS:

   1. Improves proper tracking performance through steering wheel operation.
   2. Eases obstacle avoidance through steering wheel operation.
   3. Improves vehicle stability.
2. The TCS (traction control system) controls engine torque via throttle and fuel-cut control systems and A/T shift schedule, preventing the drive wheels from spinning. This in turn prevents the vehicle rear end from skidding to either side, resulting in improved starting ability, acceleration, as well as overall vehicle stability.
