Railway Train Operation Control Method And System

Patent No. EP3744605 (titled "Railway Train Operation Control Method And System") was filed by Crrc Changchun Railway Vehicles on Nov 22, 2019. The application was issued on Jan 4, 2023.

Patent Summary

A train operation control method based on a CTCS3+ATO system determines if automatic operation conditions are met, outputting prompt information (e.g., flickering buttons) if so. The train enters automatic operation mode upon triggering an ATO starting button on the driver platform. At intermediate stations (excluding starting/terminal stations), if the train is stationary in automatic mode and the ATO starting button is triggered, the system executes station automatic departure, section automatic operation, station automatic parking, door opening protection, and linked train/platform door control. Exit conditions for automatic mode include removal of tractions to $\ge$2 units, unavailable air brakes, speed limiting protection, service/emergency braking, isolated holding braking, or ineffective communication with the automatic operation system.
