摘　　要：提高半挂汽车列车的轨迹跟踪性,是减小其行驶通道圆,提高转向机动性和主动安全性的有效途径;本文基于半挂汽车列车弯路转向理论,提出了半挂汽车列车后轮弯路行驶轨迹跟踪数学模型,并通过simulink仿真验证了数学模型的正确性。It is an effective approach to improve the steering mobility and the active safety of the vehicle by improving the tractor-semitrailer trajectory tracking character. Then, the diameter of turning clearance circle could be decreased. Based on turning theory of tractor-semitrailer on crooked road the mathematical model is established for rear-wheel of tractor-semitrailer trajectory tracking. The validity is verified by simulating demonstration.
