Abstract
A method for controlling a hydraulic servo steering system in a vehicle includes reading out a collision warning signal to establish that a collision assistance case exists, and in response to determining that the collision assistance case exists, providing a hydraulic fluid by a hydraulic pump of the servo steering system. Serving for steering assistance has an actual volumetric flow-rate that is greater than or equal to a minimum volumetric flow-rate. The method additionally includes increasing a pump speed if the actual volumetric flow-rate is less than the minimum volumetric flow-rate, the pump speed being dependent on an engine/motor speed of a drive engine/motor interacting with the hydraulic pump.
