The invention discloses a railway vehicle and an obstacle detection method and system thereof, the effectiveness of a collision event is judged according to the size and duration of an obstacle detection signal, the false alarm phenomenon caused by the fact that an alarm is given when a pushed-away obstacle does not affect driving is avoided, the accuracy of obstacle detection is improved, the reliability of brake control is ensured when obstacle collision occurs, the safety performance of the vehicle is improved, and the influence range of obstacle collision faults is reduced; the host adopts a double two-out-of-two framework, so that the reliability of the obstacle detection system is improved, and the safety performance of the vehicle is further improved; in addition, braking is detected, the effectiveness of the output braking signal is guaranteed, closed-loop feedback and fault self-inspection of the obstacle detection system are achieved, and the safety performance of the vehicle is further guaranteed.

    本发明公开了一种轨道车辆及其障碍物检测方法与系统,通过障碍物检测信号的大小和持续时间来判断碰撞事件的有效性,避免了被推开的障碍物不影响行车而发出报警导致的误报现象,提高了障碍物检测的准确性,保证了在障碍物碰撞发生时进行制动控制的可靠性,提高了车辆安全性能,降低了障碍物碰撞故障的影响范围;并且主机采用二乘二取二架构,提高了障碍物检测系统的可靠性,进一步提高了车辆安全性能;还对制动进行检测,保证输出的制动信号的有效性,实现了障碍物检测系统的闭环反馈和故障自检,进一步保证了车辆安全性能。
