Operation

The circular motion of the steering wheel is converted into linear motion of the rack by engaging the rack and
pinion inside the steering gear. The rack can push and pull the tie rod by lateral motion, thus changing the
direction of the front wheel.
The EPS controller controls the rotating direction of steering motor and the assisting current level based on
the torque sensor signals to finish the steering assist. When the vehicle is not turning, the EPS controller does
not send command to the steering motor controller, and the steering motor does not operate.
