The invention provides a semi-trailer traction towing table active steering vehicle, a long marshalling train and a steering control method, and belongs to the technical field of train steering. The semi-trailer traction towing table active steering vehicle comprises a front steering towing table and a semi-trailer, the front end of the semi-trailer is erected on the front steering towing table, and the front steering towing table is used for being connected with a front vehicle; the front steering dragging table comprises a rotation driving device, a front dragging table axle and wheels on the two sides, and the rotation driving device can drive the front dragging table axle to rotate so that the rear vehicle can move along the moving track of the front vehicle. The invention further provides a long marshalling train and an active steering control method of the trailer, track following of the full trailer without limitation of the pitch number is achieved through active steering of the front steering towing table, meanwhile, a calculation method of an active steering angle is given, it is ensured that the tractor and all rear vehicles run on the same track, and the control method is suitable for large-scale popularization and application. The problem of track deviation is solved.

    本发明提供一种半挂牵引拖台主动转向车辆、长编组列车及转向控制方法,列车转向技术领域,半挂牵引拖台主动转向车辆包括前转向拖台和半挂车,半挂车的前端搭设于前转向拖台上,前转向拖台用于与在前的车辆连接,前转向拖台包括回转驱动装置、前拖台车桥和两侧车轮,回转驱动装置能够驱动前拖台车桥回转以使得在后的车辆沿着在前的车辆的移动轨迹移动。本发明还提供了一种长编组列车以及挂车主动转向控制方法,本发明通过前转向拖台的主动转向实现不限节数的全挂车的轨迹跟随,同时给出了主动转向转角的计算方法,确保牵引车与后方所有车辆均在同一轨迹上行驶,解决了轨迹偏差问题。
