The invention discloses a high-speed train auxiliary driving control method and system, and the method comprises the steps: constructing a high-speed train operation process end-edge-cloud cooperation system, and constructing a speed and level mechanism characteristic model based on the dynamic analysis of the speed change mechanism characteristics and level change mechanism characteristics of the high-speed train operation process; determining a high-speed train aided driving control strategy prediction model based on the LSTM according to the train and line data, the speed and level mechanism characteristic model and the LSTM neural network structure obtained from the cooperative system; the edge layer is combined with data acquired in real time and data acquired by the end layer, and determines a high-speed train aided driving control strategy by using an LSTM-based high-speed train aided driving control strategy prediction model which is downloaded from the cloud layer, is established offline based on a large amount of historical data, and is based on the LSTM; and the information is sent to a vehicle-mounted edge computing node through a 5G network to carry out auxiliary driving control. The method can improve the prediction accuracy of the auxiliary driving control strategy in the operation process of the high-speed train.
