ABS System

Overview

Anti-lock braking system (ABS) detects the wheel speeds by means of the wheel speed sensors. When a
wheel skids or tends to lock up, its electronic control unit (ECU) adjusts the braking force applied on the
wheel on the real-time basis according to the signal from the wheel speed sensor, thus preventing the
wheel from skidding or locking up, improving the steering control ability and driving stability of the
vehicle in an emergency, ensuring that the driver can carry out an effective emergency avoidance
operation, and reducing the emergency braking distance under most road conditions. The ABS system
consists mainly of ECU, electronic valve (adjusting valve), wheel speed sensors, ABS fault indicator light,
and diagnostic system.
