How Do ABS Sensors Keep Your Driving Safe?

An Anti-Lock Brake System (ABS) sensor is a vital safety part. It cooperates with the vehicle’s ABS control module to stop wheels from locking up during emergency braking, helping drivers keep steering capability and vehicle stability even on slippery roads.

Modern vehicles are equipped with a full set of ABS-related sensors. They deliver real-time data to the control unit, enabling accurate and responsive braking performance.

Working Principle

Wheel Speed Sensor: Installed on each wheel, it uses magnetic and coil components to detect rotating speed and transmit corresponding electric signals to the ABS module.
Yaw Rate Sensor: Adopts piezoelectric technology to monitor the vehicle’s vertical-axis rotation, capturing acceleration and deceleration changes.

The ABS module analyzes data from wheel speed sensors, yaw rate sensors and lateral acceleration sensors to judge potential wheel lock. Once detected, the system dynamically adjusts brake pressure to retain tire traction and driving stability. Meanwhile, it links with the engine ECU to moderate power output for better road grip.
