Research on Automatic Driving Control Strategy for Freight Locomotives in Key Scenarios

At present, the locomotive automatic driving device has been applied to multiple lines and has achieved certain phased results. Due to factors such as complex application scenarios, strong non-linearity and discreteness of control objects, some problems and challenges have arisen during the operation assessment, including impulsive and surging phenomena during train interval operation, non-compliance with station benchmark parking accuracy requirements, failure to start on steep slopes, and difficulty in evaluating air braking performance. These problems seriously affect the smoothness of operation and driving safety. The article studies the automatic driving control technology for key scenarios. Through in-depth analysis of operating procedures and historical operating data, optimization of train dynamics model parameters, establishment of accurate basic resistance models and air braking models, design of expert knowledge base for smooth operation strategy, intelligent parking control strategy, air braking t
