WEIGHTING AN APPLICATION OF AN ASSISTANCE FUNCTION IN A POWER STEERING SYSTEM OF A VEHICLE

摘要

Method for modulating an application of an assistance function of a power steering system in a vehicle, said vehicle comprising, at least two wheels, a steering wheel, an assistance motor applying an assistance torque (CRP) on a rack, said method implementing an evaluation step (3) of an application gain (GA) of said assistance function, an estimation step (2) of the assistance torque associated with said assistance function (CR), and a step of multiplying (4) the assistance torque associated with said assistance function (CR) and application gain (GA), characterized in that the evaluation step (3) of the application gain (GA) comprises a first phase (31) of determining a first gain (G1) dependent on a yaw speed (VL) and an angle of the steering wheel direction (αD).
