What Is Torque Sensor?

The rack & pinion gear connected to the tire supporting the actual weight of vehicle constrains the revolving of universal joint when the driver turns the steering wheel. At this time, a kind of spring, the torsion bar between the column output shaft and input shaft is twisted.

In other words, this sensor detects the driver's intention of steering by measuring the amount of torsion (Steering angle)
