摘要
对SUV在高速转向时的侧翻稳定性进行研究,建立Carsim车辆动力学模型,基于轮胎动态的横向载荷转移原理,设计了一种通过模糊控制方法控制侧向加速度调节车轮制动力实现SUV主动抗侧翻的防侧翻控制器,针对高速紧急工况下SUV车型侧翻过程在Simulink环境中对车辆模型进行动态侧翻稳定性仿真分析。
The rollover stability of SUV in high speed steering was studied;a vehicle dynamics model was built with the software of Carsim. Based on the lateral load transfer principle of dynamic tire, an anti-rollover controller was designed, and the lateral ac-celeration was controlled through fuzzy control method to regulate wheel braking force in order to achieve the excellent active antirollover. The model of the vehicle was stability controlled in the software of Simulink. Through the simulation test with the vehicle without any controllers and the vehicle with traditional ESC, the results show that the controller can improve the anti-rollover ability of SUV under limit conditions, and improve the handling stability of SUV.
