Modern trackless train has the characteristics of long body and many articulated modules, and the steering control is extremely difficult. This paper first established its Adams dynamic model, and then designed a fuzzy PID controller to generate the yaw moment and rear wheel angle. So that the vehicle can track the trajectory of the first axle when turning. Finally, the control model was established in Matlab and simulated jointly with Adams model. The simulation experiments under step input and sinusoidal input were carried out. The results show that the active steering control strategy based on the combination of direct yaw moment and rear wheel angle can meet the requirements of vehicle steering stability and trajectory following.
