Power-Steering Support

Power-steering support is implemented by a conventional rack-and pinion power steering system. Servotronic is available as an option. The electronics and the software for Servotronic are incorporated in the SGM if active front steering is not fitted. For the active front steering system, the software for power-steering support is incorporated in the active front steering control unit. The output stage for activating the Servotronic valve and the valve in the hydraulic pump (ECO) is located in the SGM. The ECO regulates the hydraulic flow rate in the hydraulic pump in order to provide only the flow rate currently required for the power steering.
