Problems solved by technology

However, because various modes can occur when complex limiting speed profiles are given, it is not easy to respond with only the profile calculation mode described above
That is, with the method described above it is not easy to respond to an arbitrary limiting speed profile depending on the location, so a limitation of the flexibility of automatic train operation arises

Abstract

The present disclosure relates to an apparatus and method for controlling speed in an automatic train operation, capable of estimating and controlling a speed at which a train should run at each position where the train will run in order to satisfy a restrictive speed profile and to make passengers comfortable by observing acceleration limit and jerk limit in case of accelerating or decelerating the train.

Description

[0001] This application claims the prior filing date and priority benefit of Korean Patent Application No. 10-2009-0078059 filed on Aug. 24, 2009, the entire contents of which are hereby incorporated. technical field [0002] The present disclosure relates to a method and apparatus for controlling speed in automated train operation. [0003] More specifically, the present disclosure relates to such a method and apparatus for controlling speed in automatic train operation, which is capable of estimating and controlling the speed at which the train should travel at each location it will travel to, so as to meet the speed limit curves, and passenger comfort by respecting acceleration limits and jerk limits once the train accelerates or decelerates the train. Background technique [0004] Signal control equipment in the railway field is constructed from the technologies of various signaling devices and control systems that are used to prevent accidents, promote safe operation of...
