What is the Function of a Torque Sensor?
1 Answers
Torque sensor is used to: measure the torque transmitted between the steering wheel and the output shaft of the steering gear, and convert the torque magnitude into a voltage signal sent to the ECU. The torque sensor, also known as a torsion sensor, moment sensor, torque meter, or torque gauge, is categorized into dynamic and static types. As a crucial electronic control component in electric power steering systems, its principle is similar to that of a potentiometer. The two input terminals are connected to the VCC and GND ports of the electronic control unit via circuits, supplying 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 circuits.
