ABS is an anti-lock braking system that helps shorten braking distance by preventing wheel-locking in slippery road conditions. It does this by controlling the brake fluid pressure. ABS brakes consist of ECU, HCU, and wheel speed sensors: the ECU serves as the brain of the system; the HCU increases or decreases the oil pressure that is produced when working the pedal; and the wheel speed sensors sense the speed of the four wheels and measure the road conditions. The wheel speed sensors are positioned at the four wheels and send information to the ECU. The ECU calculates the wheel’s slippage, checks the road surface, and gives an order to the HCU so that the braking power can be maximized in all conditions. The HCU operates the motor and value, directly decreasing, maintaining or increasing the brake fluid pressure, and thus controlling the brakes mounted on the wheels.
ABS brakes automatically control the brake fluid pressure, prevents wheel locking, shortens braking distance, and facilitate control of the steering. However, this should not be used to justify driving above safe speeds, because the system cannot overcome the physical rules of nature.
