Abstract: Automatic Train Operation (ATO) has been widely applied to the onboard signaling system of subway trains, which improves the operation efficiency of subway trains. The braking performance of the train has a greater impact on the precise stop controlled by ATO. The train braking performance, especially the air braking performance, may be unstable to a certain extent, and the response to ATO's braking command may have a large deviation. One of the more important factors is the influence of season and temperature. This paper explores the method of optimizing the seasonal deviation of train braking and adding the adaptive ability of ATO system. In combination with the braking performance change of a certain line, a separate braking control strategy group is made for each braking change period, and switch and adjust is conducted automatically in the corresponding time period (or other setting conditions), so that under different train braking performance, ATO system can achieve precise stopping at the platform and improve the efficiency of passengers getting on and off.

Key words: ATO, control strategy by ATO, seasonal variation of ATO stopping accuracy
