Abstract

The invention discloses an automatic-driving control system and control method for high-speed train capable of preventing signal overrunning, belonging to the technical field of the high-speed train automatic driving system. The system comprises a train operation curve generation module, which is used for generating an expected operation control curve of the high-speed train. A train position coupling module, configured to obtain distance-time coupling information of the train according to a desired operation control curve; a train speed coupling module, configured to obtain the train speed-time coupling information according to the desired operation control curve and the distance-time coupling information; the train acceleration control module is configured to control the acceleration ofthe train according to the speed-time coupling information. The invention realizes the automatic operation of the high-speed train by generating the train operation control curve under the ATP protection curve. At the same time, through the organic fusion of ATP and ATO data, the overspeed and overdistance operation of high-speed train is avoided, the false alarm or emergency braking event causedby overspeed and overdistance is avoided, and the operation efficiency of high-speed train is improved.
