The invention discloses a train time source for measuring a time difference between train information sources. The train time source comprises a detection module (DM), a time measurement module (TMM),a transmission module (TM) and a power supply module (PM). The DM detects a train information source (VS) to generate a time measurement signal (MS) and sends the MS to the TMM. The TMM generates time difference time measurement data (TD) between events when different vehicle information sources reach the same space and sends the TD to the TM. The TM generates a time measurement data array transmission signal (TS) and sends the TS to the air space. A train control method comprises that the train obtains the time measurement data array through the TS to calculate a time interval lower limit value (TLLTI) required for ensuring the current train driving safety, and when the time interval reaches the TLLTI, uses braking control to recover the time interval obtained when the train drives to the front and keep the time interval above the TLLTI. According to the invention, the train can automatically and autonomously adopt credible control for a preceding train to effectively overcome the high-speed rear-end collision risk. The invention further provides a preceding train braking intention recognition method, a preceding train integrity checking method and a preceding train early-stage speed measuring method.

    一种测量车辆信源间时间差的车时源,包括检测模块DM、测时模块TMM、传送模块TM和电源模块PM,DM检测车辆信源VS生成测时信号MS送至TMM,TMM生成不同车辆信源到达相同空间事件间时间差测时数据TD送至TM,TM生成包括测时数据数组传送信号TS送至空气空间。一种列车控制方法,列车以TS获取测时数据数组依此计算出保证当前列车行驶安全所需要的时间间隔下限值T,判断当时间间隔达到T时采取制动控制使行驶到达前方获取的时间间隔恢复且保持在T之上。利用本发明,列车可以自动针对其在先列车自主采取可信控制有效克服高速追尾风险。本发明还提供一种在先列车制动意图识别方法、一种在先列车完整性检查方法和一种在先列车前期速度测量方法。
