The invention discloses a virtual coupling tracking control system and method for a railway vehicle, and the system comprises a wireless communication unit which is used for achieving the automatic communication connection between a front railway vehicle and a rear railway vehicle through a wireless communication technology; the self-sensing identification unit is used for autonomously identifying the front vehicle when the vehicle enters the virtual coupling operation mode and sensing and measuring the running state information of the two vehicles in real time, and the running state information comprises vehicle kinetic parameters, the relative distance between the vehicles, the relative speed and the acceleration information; the relative braking distance calculation unit is used for calculating the relative braking distance of the front and rear vehicles in real time according to the vehicle state information sensed in real time by taking guiding safety as a target; the self-adaptive tracking control unit is used for determining the expected traction braking force of the rear vehicle by adopting a self-adaptive reward and punishment method based on the traction braking force of the front vehicle; and under the constraint condition that the distance between the front vehicle and the rear vehicle is always larger than the relative braking distance, the expected traction braking force is used for controlling the rear vehicle to run in a self-adaptive tracking mode.

    本发明公开了一种轨道车辆的虚拟联挂追踪控制系统及方法,包括:无线通信单元,用于使用无线通信技术实现前后轨道车辆之间的自动通信连接;自感知识别单元,用于在车辆进入虚拟联挂运营模式时,自主识别前方车辆,并实时感知测量两车辆运行状态信息,包括:车辆动力学参数、车辆间的相对距离、相对速度和加速度信息;相对制动距离运算单元,用于根据实时感知的车辆状态信息,以导向安全为目标,实时计算前后车辆相对制动距离;自适应追踪控制单元,用于基于前车的牵引制动力,采用自适应奖惩方法确定后车的期望牵引制动力;以前后车辆之间的距离始终大于相对制动距离为约束条件,以所述期望牵引制动力控制后车自适应追踪运行。
