摘要
针对重型车辆防侧翻控制算法进行研究,基于差动制动防侧翻理论,将模糊控制与PID控制相结合,设计车辆防侧翻控制器,将车辆输入输出参数模糊化,进行模糊推理及解模糊化,建立模糊规则,开发基于预警的车辆防侧翻PID控制算法,在双移线转向输入工况下对基于差动制动和模糊PID控制的重型车辆防侧翻控制算法进行仿真分析,从仿真结果可以看出车辆在双移线试验工况中施加控制后横摆角速度、质心侧偏角及侧向加速度都得到改善,提高了车辆行驶的稳定性。结果表明基于差动制动和模糊PID控制的重型车辆防侧翻控制算法能够有效的防止车辆侧翻。
Fuzzy control and PID control are combined to study the anti-rollover control algorithm of heavy vehicle based on the differential braking anti-rollover theory.The Vhicle input and output parameters all deal with fuzzy measure,and inference rules are established,Anti-rollover PID Control Algorithm for heavy vehicle based on Early Warning are designed.The simulation results show that the yaw rate,the centroid side angle and the lateral acceleration of the vehicle are improved after the control of the vehicle in Lane Change Test condition,and the stability of the vehicle is improved.The results show that the control algorithm base on differential braking and fuzzy PID control can effectively prevent the vehicle from turning over.
