摘要: 为提高重型半挂汽车列车在极限工况下的防侧翻稳定性,建立了侧向、横摆、侧倾运动的牵 引车和挂车 5自由度动力学模型。运用模型预测控制方法,决定目标控制横摆力矩。以车辆实时横摆 角速度和轮胎载荷转移率为决策依据,对主动转向和直接横摆力矩控制两子系统,进行协调控制。用 TruckSim/Simulink平台,进行联合仿真分析。结果表明:在相同工况下,牵引车、挂车的侧向加速 度最大值分别改善了 7.76%、12.29% ;横摆角速度最大绝对值分别改善了 23.88%、3.39% ;重型半 挂半挂汽车列车的最大铰接角减小了19.87%。因而,相对于传统方法,该防侧翻分层递阶控制,提 高了重型半挂汽车列车的防侧翻稳定性。

Abstract:  A 5 degree-of-freedom dynamic model was established for tractor and trailer lateral with yaw and roll motion for the rollover stability of heavy-duty semi-trailer trains under extreme conditions. A model predictive control method was used to obtain the yaw moments of tractor and trailer with an anti-rollover target controls. Two subsystems of active steering and direct yaw moment control were coordinated and controlled according to the vehicle real-time yaw rate and the tire load transfer rate. The joint simulation analysis was done by using TruckSim/Simulink pair for a layered hierarchical control strategy of semi-trailer. The results show that the maximum lateral accelerations are improved with the rates of 7.76% and 12.29% for the tractors and the trailers respectively under same conditions, the maximum absolutes of yaw angula-rate are improved with the rates of 23.88% and 3.39% respectively, and the maximum articulation angle of the car train is reduced by 19.87%. Therefore, the layered hierarchical control improves the anti-rollover stability of the vehicles due to active steering and direct yaw moment control compared with the traditional heavy-duty semi-trailer train.
