Abstract
A vehicle stability control method is to be performed by a vehicle stability control system of a motor vehicle, and includes the steps of: detecting an actual yaw rate, and obtaining a plurality of detection values by detecting a vehicle speed and a steering wheel angle, and at least one operation status selected from a lateral acceleration status, a load status and a steering wheel angular speed status; obtaining a plurality of intermediate weight values, from which a steering characteristic value is determined, based on the obtained detection values; obtaining a target yaw rate based on the vehicle speed, the steering wheel angle and the steering characteristic value; and controlling steering of road wheels according to difference between the target and actual yaw rates.
