wheel speed
Wheel speed sensors are critical components in modern vehicle safety and performance systems, serving as essential elements in anti-lock braking systems (ABS) and traction control. These sophisticated devices continuously monitor the rotational velocity of each wheel, providing real-time data to the vehicle's electronic control unit. Operating through electromagnetic principles, wheel speed sensors generate electrical signals proportional to the wheel's rotation rate, typically producing between 100 to 2000 pulses per revolution depending on the specific application. The sensor consists of a permanent magnet and a toothed ring, creating magnetic field variations that are converted into electrical signals as the wheel rotates. This technology enables precise measurement of individual wheel speeds, which is crucial for maintaining vehicle stability and optimizing brake force distribution. Modern wheel speed sensors have evolved to incorporate advanced features such as integrated diagnostics and enhanced signal processing capabilities, making them more reliable and accurate than ever before. These sensors play a vital role in various vehicle systems, including electronic stability control, hill-start assist, and adaptive cruise control, contributing significantly to overall vehicle safety and performance optimization.
