摘要： 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.

摘要： A method for performing an evasive maneuver with a commercial vehicle-trailer combination includes ascertaining that a collision between the commercial vehicle-trailer combination and a collision object is impending. The method further includes determining an evasion trajectory by which the commercial vehicle-trailer combination can evade the collision object without coming into contact with the collision object, determining a desired steering angle based on the evasion trajectory and activating an active steering system of the commercial vehicle-trailer combination in dependence on the determined desired steering angle such that the commercial vehicle-trailer combination moves along the evasion trajectory from a starting traffic lane to a target traffic lane so as to perform the evasive maneuver. The method additionally includes determining a desired vehicle deceleration and initiating an electronic braking system of the commercial vehicle-trailer combination in dependence on the desired vehicle deceleration so as to brake the commercial vehicle-trailer combination.

摘要： A method for determining a coefficient-of-friction, the method including braking a first wheel of a vehicle such that a slip between the first wheel and a roadway is less than a slip between a second wheel of the vehicle and the roadway, and determining a coefficient-of-friction between the first wheel and the roadway based on the behavior of the first wheel during the braking. The method optionally including hazard braking the vehicle.
