Abstract: In the ideal tracking interval, the tracking train is susceptible to the operation of the preceding train; and effective braking must be taken to maintain the safety distance. In order to avoid the interference from the preceding train, improve the comfort of the tracking train and reduce the braking energy consumption of the train, the tracking process was firstly divided into different stages by using the idea of segmentation, and the coasting interval required for tracking the train in each stage was calculated separately. At the same time, Bang-Bang control idea was used to optimize the coasting interval in different stages, so as to ensure the operation efficiency of the line. Through the simulation analysis of MATLAB, the interval tracking spacing became larger after adding the coasting interval, but in exchange for better comfort of tracking train and lower braking energy consumption.
