Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
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.
Claim 2
Dependent Claim
183 words
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.
Claim 3
Dependent Claim
206 words
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.
Claim 4
Dependent Claim
206 words
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.
Claim 5
Dependent Claim
38 words
A system according to claim 2, wherein the first receiving means receives the time at which at least one of the fixed locations will become clear for use from the other of said first and second railway vehicles.
Claim 6
Dependent Claim
36 words
A system according to claim 2, wherein the first receiving means receives the time at which at least one of the fixed locations will become clear for use from a central regulation unit of the system.
Claim 7
Dependent Claim
26 words
A system according to claim 2, wherein the reporting means reports the calculated arrival time directly to the other of said first and second railway vehicles.
