Regulating a railway vehicle
First Claim
1. Apparatus for use in a first railway vehicle for regulating said vehicle, the apparatus comprising:
- calculating means for calculating running profiles of distance with respect to velocity among a plurality of fixed locations;
first receiving means for receiving the time at which at least one of the fixed locations will become clear for use by said first railway vehicle;
second receiving means for receiving the timetabled arrival and departure times scheduled for said first railway vehicle at any of said fixed locations;
means for controlling the calculation by said calculating means of a calculated running profile on the basis of the information received by the first and second receiving means by selecting and optimizing one of journey time, power consumption and inter-vehicle headway;
said calculating means further calculating an arrival time of said first railway vehicle;
means for operating the traction and braking system of said first vehicle for use in driving said first vehicle to the calculated running profile; and
means for reporting to a second railway vehicle the calculated arrival time of said first vehicle at any of said fixed locations.

Abstract
Apparatus for use in a railway vehicle for regulating it, comprising: means for calculating running profiles between two or more fixed destinations; means for receiving, either from a second or subsequent railway vehicle, directly or via separate means, the time at which one or more of the destinations will become clear for use by the railway vehicle; means for knowing what balance to apply to trade-offs between two or more operational strategies; means for knowing the timetabled arrival and departure times scheduled for it at any destination; and means for reporting to any second or subsequent railway vehicle, either directly or via separate means, its calculated arrival time at any destination.

2. A railway vehicle regulation system including first and second railway vehicles, wherein each of said vehicles includes apparatus for regulating the respective railway vehicle, the apparatus including:
-
calculating means for calculating running profiles of distance with respect to velocity among a plurality of fixed locations; first receiving means for receiving the time at which at least one of the fixed locations will become clear for use by the respective railway vehicle; second receiving means for receiving the time tabled arrival and departure times scheduled for the respective railway vehicle at any of said fixed locations; means for controlling the calculation by said calculating means of a calculated running profile on the basis of the information received by the first and second receiving means by selecting and optimizing one of journey time, power consumption and inter-vehicle headway; said calculating means further calculating an arrival time of one of said first and second railway vehicle; means for operating the traction and braking system of the respective railway vehicle for use in driving the respective vehicle to the calculated running profile; and means for reporting to the other of said first and second railway vehicles the calculated arrival time of the respective vehicle at any of said fixed locations. - View Dependent Claims (3, 4, 5)
