The invention discloses a rail transit vehicle parking control method and system. The method comprises the steps of adjusting the operation electric braking force of a vehicle in real time at each braking time point according to the deviation value of the actual speed of the vehicle and a reference speed, and when the actual speed of the vehicle is reduced to Vt, unloading the electric braking force, and using air braking for reaching a parking point. Parking control is divided into two stages, a virtual calibration point is set in the first stage, and the braking force is adjusted in real time according to the deviation value of the position speed of the virtual calibration point and the reference speed. In the second stage, a sliding section at the front end of the parking point is set,after the vehicle reaches the calibrationalignment point, the vehicle travels in a force unloading mode, and finally air braking is used for accurate parking. According to the method, the control precision of electric braking and air braking can be greatly improved, the phenomena of over-calibration and under-calibration are prevented, and the vehicle running efficiency is improved.
本发明公开了一种轨道交通车辆停车控制方法及系统,在每一个制动时间点,根据车辆的实际速度与基准速度的偏差值,实时调整车辆运行电制动力;当车辆实际速度降至Vt时,卸载电制动力,使用空气制动到达停车点。本发明将停车控制分两个阶段,在第一阶段设定虚拟标定点,并根据虚拟标定点位置速度与基准速度的偏差值,实时调整制动力。在第二阶段设定停车点前端滑行段,车辆到达对标点后,采用卸力方式行进,最终使用空气制动精准停车。本发明可以极大地提高电制动和空气制动的控制精度,防止停车时出现冲标和欠标现象,提高车辆运行效率。
