Abstract:This paper studies the automatic driving control technology of freight trains and proposes an automatic driving control system with perception,planning and control that integrates the existing network and signal system.A target curve planning method is proposed based on the train signal,line information data,and train model. The information about train running conditions,target force,target air brake decompression,and so on is planned in real time. With the target curve information as the control fedforward,the feedforward control technology with operating condition constraints is used to control the train operation in real time. In order to improve the accuracy of control,the parameter identification technology based on the Kalman filter is adopted. Speed and acceleration information are used as state quantities to identify train parameters. According to the proposed train automatic driving control framework of planning-control-parameter identification,the whole-line train automatic driving testfrom zero speed activate to aceleration,interval operation,deceleration and stop has been successfully carried out on the test train. The test results indicate that the control method proposed in this paper is practical and meets application requirements.
