ABS Sensor: A Comprehensive Global Guide for Automotive Professionals and Buyers

Introduction to ABS Sensors: Function, Types, and Core Technology

An Anti-lock Braking System (ABS) sensor, also known as a wheel speed sensor, is a critical component in modern automotive safety systems. Its primary function is to monitor the rotational speed of each wheel and transmit this data to the 电子设备 Control Unit (ECU). The ECU uses this information to detect wheel lock-up during braking, modulating brake pressure to maintain traction and steering control. ABS sensors are typically either passive (variable reluctance) or active (Hall effect or magnetoresistive). Passive sensors generate an AC signal as a toothed ring passes by, while active sensors, which are more common in modern vehicles, produce a digital square wave signal that provides accurate speed data at very low speeds. The global demand for ABS sensors is driven by increasing vehicle production, stricter safety regulations (such as mandatory ABS in many countries), and the growing adoption of Advanced Driver-Assistance Systems (ADAS).
