基于模型预测控制的汽车底盘协调控制策略

通过电子控制系统主动干预车辆的纵向、横向和垂向动力学特性，可以提高车辆的稳定性和操纵性，进而保证车辆的安全行驶。将主动转向、主动横摆力矩控制和主动悬架结合，根据轮胎的力学特性，利用模型预测控制策略，通过轮胎力分配，实现底盘三向动力学的协调控制，并进行了仿真验证，结果表明与两向动力学协调控制相比，该控制策略可以有效提高整车的主动安全性。

Vehicle Chassis Coordination Control Strategy Based on Model Predictive Control

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.
