Abstract :
This paper describes an advanced vehicle control method using independent four wheel steering system and roll stiffness control for advanced vehicle control system (AVCS) handling and stability. At accelerating and at braking on a cornering of a vehicle, each tire force coefficient of the vehicle is very different because of load transfer and nonlinearity of tire forces. Therefore, four-wheel-steering (4WS) system is not effective for the vehicle control and stability not only at high lateral accelerating condition but also a low coefficient of friction. If the tire force coefficient are controlled, it is possible that the vehicle has more stable behavior even at the critical situation. In this paper, it is shown that the integrated vehicle control using independent 4WS and roll stiffness control with a tire load rate has a good effect to the vehicle stability
