Problems solved by technology

That is, even if the train could travel at a faster speed, there is no other way than to allow the train to travel at a slower speed due to fear of possible emergency braking
[0014] As such, the conventional train running system has a drawback in that the number of train runs on the relevant line is reduced, thereby lowering operational efficiency from an economical point of view

Embodiment Construction

[0046] Various exemplary embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some exemplary embodiments are shown. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. On the contrary, the described aspects are intended to embrace all such modifications, improvements, and variations that fall within the stated scope and novel aspects of the present disclosure.

[0047] This disclosure relates to train speed limits for the ATO, which is an automatic train operating device and employs a model-based observer design to predict future train speeds, calculating when a train will exceed the ATP speed limit in such-and-such seconds value and prevents the train from facing a hazardous situation by performing a service braking operation before the train exceeds the speed limit to allow emergency braking.

[0048] That is, TTSLC{inte...

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.

Description

technical field [0001] Teachings according to exemplary embodiments of the present disclosure relate generally to apparatus for controlling the speed of a railway vehicle, and more particularly to apparatus for controlling the speed of a railway vehicle in an automated train operation system. 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 (running) is to make the train run at a predetermined target speed in each operation section, and to enable the train to stop effectively and safely at the designated position of the railway station, and to effectively and Safely run trains between stations. [0004] Automatic train operation can be achieved without a driver, and even if there is a driver, the driver does not have to actively participate in the operation of the train, but only provides a minimal portion of the brake...
