Research of automobile stability system with four wheel steering by variable structure control with sliding mode

According to the Direct Yaw Moment Control method and Variable Structure Control with Sliding Mode,based on vehicle side-slip angle and yaw rate,3 different kinds of vehicle handling stability controller are designed.At Simulink simulation flat,do simulation experiment of the concept car model with the direct yaw moment control;and which control strategy should be apply in different specifically vehicle working conditions,how the control parameters impact the control quality have been studied.
