摘　　要：分析了半挂汽车列车转向的特点,对其稳定性控制原理进行了研究,包括横摆角速度跟踪控制和防倾覆控制。在此基础上,建立了半挂汽车列车多体动力学模型,采用虚拟样机技术,对横摆角速度跟踪控制和防倾覆控制进行运动学与动力学仿真。结果表明,装用车辆动态控制系统后,提高了半挂汽车列车高速紧急避障时的操纵稳定性,因而,其避障行驶的极限条件大大宽松。The feature of steering control, including yaw rate tracking control for semi-trailer combination is analyzed, and the principle of stability and anti-roll control, is studied. Based on this, a multi-body model for semi-trailer combination is set up, and the kinematics and dynami dynamics cs simulations for yaw rate tracking and anti-roll controls are performed using virtual prototype technology. The results show that with vehicle dynamics con- trol, the handling and stability of semi-trailer combination in high-speed obstacle avoidance are improved, and hence the limit conditions for its obstacle avoidance operation are greatly relaxed.
