The invention relates to the technical field of railway vehicles, and provides a railway vehicle overspeed control method and system and a railway vehicle. The rail vehicle overspeed control method comprises the steps that the vehicle speed is obtained; upon determining that the vehicle speed is greater than the first speed threshold and less than the second speed threshold, applying blockade traction; upon determining that the vehicle speed is greater than a second speed threshold, lockout traction, emergency braking, and maximum service braking are applied. When the vehicle speed of the rail vehicle exceeds a first speed threshold, blocking traction is applied. And if the vehicle speed continues to rise and exceeds the second speed threshold value, emergency braking is applied, the maximum service braking serves as redundancy, the speed reduction effect is improved, and the vehicle running safety is improved. Graded control deceleration is carried out after the vehicle is overspeed, the vehicle deceleration effect can be effectively improved, and safe and stable operation of the vehicle is guaranteed.
本发明涉及轨道车辆技术领域,提供一种轨道车辆超速控制方法、系统及轨道车辆。其中,轨道车辆超速控制方法,包括:获取车辆速度;在确定车辆速度大于第一速度阈值且小于第二速度阈值时,施加封锁牵引;在确定车辆速度大于第二速度阈值时,施加封锁牵引、紧急制动及最大常用制动。在轨道车辆的车辆速度超过第一速度阈值时,施加封锁牵引。若是车辆速度继续升高且超过第二速度阈值时,施加紧急制动并通过最大常用制动作为冗余,增加减速效果,提高车辆运行的安全性。在车辆超速后进行分级控制减速,能够有效地提高车辆减速效果,以及保证车辆运行安全稳定。
