How Does the Power Steering System Work?

[StArcher]

The working principle of the power steering system is that when the steering shaft rotates, the torque sensor converts the relative angular displacement generated between the input and output shafts under the action of the torsion bar into an electrical signal and transmits it to the ECU. The ECU determines the rotation direction of the motor and the magnitude of the assist current based on the signals from the vehicle speed sensor and torque sensor, thereby achieving real-time control of the power steering. Solutions for when the power steering system warning light is on: Check whether the generator, power steering pump, and steering mechanism are damaged; inspect the connection points of each component for looseness; verify that the tire pressure is within the normal range; replace the power steering pump or steering mechanism components if necessary. Components of the automotive power steering system: It consists of a torque sensor, vehicle speed sensor, electronic control unit (ECU), motor, and electromagnetic clutch.
