Abstract
Abstract The present invention relates to an automated railway system and to a method of leading a vehicle by means of a control center from an automatically controlled area to an area of individual control. The speed-determining criteria in the area of individual control, for example, maximum speeds and stopping points, are stored in the control center and used to determine a transition speed and a transfer point which, in turn, are communicated as corresponding running commands to the vehicle still being in the area of the control center.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
98 words
A method of leading a vehicle by means of a control center from an automatically controlled area to an area of individual control, taking into account signals and the like, comprising the steps of storing in said control center speed determining criteria in the area of individual control, e.g. maximum speed and stopping points; determining from said stored criteria a transition speed between said two areas and a transfer point between said two areas; and communicating said transition speed and said transfer point as running commands to said vehicle when it is still in said automatically controlled area.
Claim 2
Independent Claim
98 words
A method of leading a vehicle by means of a control center from an automatically controlled area to an area of individual control, taking into account signals and the like, comprising the steps of storing in said control center speed determining criteria in the area of individual control, e.g. maximum speed and stopping points; determining from said stored criteria a transition speed between said two areas and a transfer point between said two areas; and communicating said transition speed and said transfer point as running commands to said vehicle when it is still in said automatically controlled area.
Claim 3
Dependent Claim
45 words
A method according to claim 1, further including the steps of reducing the speed of said vehicle in said automatically controlled area to the maximum speed permissible in said area of individual control, and said transfer point is the common boundary of said two areas.
Claim 4
Dependent Claim
46 words
A method according to claim 1, wherein said transfer point is the common boundary of said two areas, and said transition speed is selected so that said vehicle can be stopped by individual control at the first possible stopping point in said area of individual control.
Claim 5
Dependent Claim
67 words
A method according to claim 1, further including the step of reducing the speed of said vehicle in said automatically controlled area as if said vehicle were to stop at the common boundary of said two areas; and turning said vehicle over to individual control by said control center before said common boundary when said vehicle has reached the maximum permissible speed in said automatically controlled area.
Claim 6
Dependent Claim
55 words
A method according to claim 1, further including the steps of reducing the speed of said vehicle in said automatically controlled area until said vehicle could be stopped by individual control at the first possible stopping point in said area of individual control; and turning said vehicle over to individual control by said control center.
Claim 7
Dependent Claim
32 words
A method according to claim 1, further including the step of turning said vehicle over to individual control by said control center before a last distance signal within said automatically controlled area.
