Abstract:
1. A vehicle stability control method to be performed by a vehicle stability control system of a motor vehicle, said vehicle stability control method comprising the steps of: a) detecting an actual yaw rate of the motor vehicle, and obtaining a plurality of detection values by detecting a vehicle speed of the motor vehicle, a steering wheel angle of the motor vehicle, and at least one operation status selected from a lateral acceleration status, a load status and a steering wheel angular speed status of the motor vehicle; b) obtaining a plurality of intermediate weight values, from which a steering characteristic value is determined, based on the detection values obtained in step a); c) obtaining a target yaw rate based on the vehicle speed, the steering wheel angle and the steering characteristic value; and d) controlling steering of road wheels of the motor vehicle according to difference between the target yaw rate obtained in step c) and the actual yaw rate detected in step a); wherein the intermediate weight values include a first weight value corresponding to the lateral acceleration status a second weight value corresponding to the load status, a third weight value corresponding to the vehicle speed, and a fourth weight value corresponding to the steering wheel angular speed status; and wherein the first weight value has a predefined negative relation to the lateral acceleration status, the second weight value has a predefined negative relation to the load status, the third weight value has a predefined positive relation to the vehicle speed, and the fourth weight value has a predefined negative relation to the steering wheel angular speed.
