Introduction to Wheel Speed Sensors
Wheel speed sensors (WSS) are critical components in modern automotive systems, primarily used in Anti-lock Braking Systems (ABS), Traction Control Systems (TCS), and 电子设备 Stability Control (ESC). These sensors monitor the rotational speed of each wheel and transmit real-time data to the vehicle’s Electronic Control Unit (ECU). By detecting variations in wheel speed, the ECU can modulate brake pressure or engine torque to prevent wheel lockup or loss of traction. There are two main types: passive (variable reluctance) sensors and active (Hall effect or magnetoresistive) sensors. Passive sensors generate an AC voltage signal as a toothed ring passes by a magnetic coil, while active sensors use a semiconductor to produce a digital square wave signal, offering higher accuracy at low speeds. Wheel speed sensors are found in passenger cars, commercial trucks, motorcycles, and even railway systems, making them indispensable for vehicle safety and performance.
