Functional features
Accurate speed measurement: By working with relevant components in the vehicle transmission system, such as the transmission output shaft, etc., using electromagnetic induction or Hall effect principles, the instantaneous speed of the vehicle is accurately measured, and converted into an electrical signal and transmitted to the vehicle's electronic control unit (ECU).
Stable signal transmission: It has good anti-interference ability and can work stably in the complex electromagnetic environment of the vehicle, ensuring that the speed signal is accurately transmitted to the ECU, providing a reliable basis for the vehicle's speedometer display, cruise control, automatic transmission shift control, etc.
Safety guarantee: It also plays an important role in the vehicle's safety system. For example, in systems such as the anti-lock braking system (ABS) and the electronic stability program (ESP), timely and accurate vehicle speed signals help the system better judge the vehicle's driving status, so as to take corresponding control measures and improve the safety of vehicle driving.
