Abstract
The present invention relates to a yaw stability control system for a vehicle using a steering system and a method of controlling by detecting the occurrence of understeer, determining the degree of understeer after the occurrence of understeer is detected determining if the determined degree of understeer exceeds a threshold value, saving the steering wheel torque value and steering wheel angle value when determined that a calculated drop in steering wheel torque exceeds the threshold value, calculating a guidance torque, a driver-intended steering wheel angle, and updating the steering wheel angle at the start of the guidance torque calculation, applying the guidance torque to the steering of the vehicle, and using the driver-intended steering wheel angle for yaw stability control.
