Description: Main principle of work: Automobile when change, the torque (changes)the sensor meeting "to feel" and plans the direction to the steering wheel moment of force which rotates, these signals can issue the electronic control unit through the data bus, the electrically controlled unit can according to the driving moment, plan data signal and so on the direction which transfers, sends out the movement instruction to the electric motor controller, thus the electric motor can according to be concrete needs to output the corresponding size the torque, thus produced has boosted changes.
