Abstract
An apparatus for controlling speed in railway vehicles is disclosed, the apparatus estimates a future train speed and determines a control input (first speed control) configured to control a train speed based on a TTSLC {Time-To-Speed-Limit Crossing, a time taken by a train from a current time to exceed an ATP (Automatic Train Protection) speed profile, which is an ATP speed limit}, and determines a control input (second speed control) configured to control the train speed based on a difference between the ATP speed profile and an actual train speed, whereby the first speed control or the second speed control is selected in response to the TTSLC and outputted to the train.
