摘要： A power steering system includes a rotary slide valve which has a housing, an input shaft and an output shaft which can be rotated relative to each other to a limited extent. A centering piston is provided which is non-rotatably and axially movably connected with the input shaft and delimits a pressure space in the housing. The rotary slide valve further comprises a centering ring which is non-rotatably connected with the output shaft, and arm inlet to the pressure chamber. The pressure chamber has a controlled outlet. There is also proposed a method of operating such a power steering system.

摘要： A method of controlling a power steering system having an adjusting mechanism for adjusting at least one vehicle wheel is disclosed herein. The system includes a steering wheel, a position sensor, and a drive system, such as a servo pump driven by an electric motor, to provide steering assistance a steering wheel and a position sensor. It is determined whether the adjusting mechanism is approaching an end position. If it is found that the adjusting mechanism is approaching the end position, then the drive system is controlled in such a way that it provides a diminishing steering assistance.
