High-frequency steering detecting method for vehicle, involves limiting brake pressure that is produced by vehicle assistance system to lower maximum pressure when state variable representing change of rotating motion exceeds limit values

摘要

The method involves determining state variable representing a change of rotating motion of a vehicle around a vehicle vertical axis, where the change of rotating motion is change in steering angle. A brake pressure (pbr) that is produced by a vehicle assistance system is limited to a lower maximum pressure (pmax) when the state variable representing the change of rotating motion exceeds limit values (Llow, Lhigh). An independent claim is also included for a vehicle assistance system i.e. electronic stability program, in a vehicle comprising a regulator and/or controller for detecting high-frequency steering in a vehicle.
