Abstract

An apparatus and method for controlling train speed are disclosed, the method including receiving an operation data, estimating a future train speed subsequent to a predetermined time of the train, using the operation data and dynamics model of a train, calculating a TTSLC {Time-To-Speed-Limit Crossing, a time when the train exceeds an ATP (Automatic Train Protection) speed limit}, and outputting a deceleration command by determining an additional braking force, in a case the TTSLC is smaller than a predetermined threshold.

Description

technical field [0001] The present disclosure relates to control technology of train speed. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] In general, the purpose of automatic train operation (operation) is to enable the train to run at a predetermined target speed in each operation section, and to enable the train to stop efficiently and safely at a designated position at a station. [0004] Automatic train operation can be achieved without a driver, and even if there is a driver, the driver does not proactively participate in the operation of the train, but provides a minimal amount of action to perform train braking in the event of an emergency. [0005] In the case of CBTC (Communication Based Train Control) operated by radio communication, train protection is performed by an ATP (Automatic Train Protection) system, and operations such as train speed control are pe...
