Abstract: Wheel speed sensor is one of the basic sensors necessary for many vehicle safety systems. The basic types of commercial electromagnetic wheel speed sensors are introduced, including the working principles (inductive, Hall and magnetic resistance, etc.) and the general ways of signal preprocessing.The characteristics and differences of different types of sensors are explained with focus on the characteristics of the sensing signals. The application of common active sensors is illustrated with some examples, including installation environment and failure examples. The development of wheel speed sensor is prospected. Through the above, the application status of wheel speed sensor is basically described, so that everyone has a clearer understanding of wheel speed sensor.
Key words: wheel speed sensor; signal acquisition; signal processing
