According to the vehicle handling stability of Steer-By-Wire,the immobile steering sensibility type and the yaw rate γ and sideslip angle β control strategy was researched.The hardware-in-loop experiment of Steer-By-Wire based on dSPACE was processed for testing the control strategy.On the basis of experiment about steering transient response in National Standards,the vehicle handling stability of the Vehicle with the control strategy was testing.
