Vehicle Chassis Coordination Control Strategy Based on Model Predictive Control

Abstract:

Through active intervention in the vehicle vertical, horizontal and vertical dynamics, electronic control systems can improve stability and steerability of vehicle, thereby ensuring the safe driving. According to the mechanical properties of the tire, this article will coordinate active steering, active yaw moment control and active suspension with the use of model predictive control and tire force allocation strategy to achieve the coordination among the vertical, horizontal and vertical dynamics. Computer simulation results showed that the control strategy could effectively improve vehicle active safety.
