摘　　要：为了兼容欧洲列车控制系统(Europe train control system,ETCS)最高版本(基线3)中高速列车的目标速度和距离监控功能,文章提出一种基于二阶Bézier曲线、避免触发紧急停车的车载速度曲线计算方法。其主要用于车载列车自动防护(ATP)系统中,利用列车的当前位置和速度来监督该速度曲线,以确保列车速度在任何时刻均处于安全范围内,能有效避免因制动造成的过度磨损并节省牵引能量。In order to complete the function of speed and distance monitoring for high speed train and be compatible with the highest version of the ETCS, it presented a real-time calculation method of train speed based on quadratic Bézier curve to avoid triggering emergency stop. The method is mainly applied for ATP. The speed profile is monitored in the train control system with the current location and speed of the train to ensure that the train speed is within safe limits at all times. This method can avoid excessive wear of braking and save traction energy.
