  • Power Steering Control Module J500

What You Should Know About the Electro-mechanical Power Steering System:

With electro-mechanical power steering, there is no requirement for hydraulic assistance to support the steering. Eliminating hydraulic oil from the steering system helps to protect the environment.

The electro-mechanical power steering system is a dual pinion type. This is characterized by two pinions (steering and drive pinions), which enable the necessary steering force to be transmitted to the steering rack.

To assist the steering, an electric motor is actuated based on input response. The system provides the driver with assistance depending on the driving conditions (servotronic).

The electro-mechanical power steering supports return of the steering wheel back to the center position via the “active return” function. This results in a well-balanced feeling and extremely accurate straight-line stability in every driving situation.

With the straight-line stability function, a force is generated and applied to make it easier for the driver to steer the vehicle in a straight line when the vehicle is being affected constantly by side winds or driven up or down hills.
