Torque sensors are used to adjust the amount of power steering assistance in a vehicle. Here is a detailed introduction to the function of torque sensors: Principle: The principle of a torque sensor is similar to that of a potentiometer. The two input terminals are connected to the VCC and GND ports of the electronic control unit (ECU) via wiring, corresponding to +5V and 0V, respectively. The two output terminals of the torque sensor, namely the main torque IN+ and the auxiliary torque IN-, are connected to the ECU through wiring. Operation Process: It measures the torque transmitted between the steering wheel and the steering gear output shaft, converts the torque magnitude into a voltage signal, and transmits it to the ECU. This, in turn, adjusts the level of power steering assistance. Importance: The torque sensor is a critical electronic control component in the electric power steering system. The quality of its output signal directly affects the safety of vehicle handling, especially for cars driving at high speeds.
