Abstract: Aiming at the algorithm strategy of Automatic Train Operation (ATO) to control the train braking, this paper first introduces the current research status of ATO train control strategy and the train braking system, and then expounds the train braking control strategy based on the calculation of chasing time. Finally, analyzes the application of this control strategy in the train control system of Hefei Line 3, and verifies the effect of ATO on the comfort and parking accuracy during the braking process of a train entering the station, which are of great significance to the research of intelligent train control strategy.

Key words:  , ATO system, braking curve, train control strategy, urban rail

摘要： 针对ATO控制列车制动的算法策略，首先介绍目前ATO控车策略的研究现状与列车制动系统。然后阐述基于追赶时间计算控制的列车制动控制策略。最后分析本控制策略在合肥3号线列控系统的应用，验证ATO控制列车进站制动过程中的舒适度与停车精准度的效果，对列车智能化控车策略的研究具有重要意义。
