Abstract

A protection method for a railway network, which is divided into section segments by section elements and can be traveled upon by vehicles. In order to optimize the vehicle sequence in the railway network, different train sequence point types are specified and different braking curves of the same braking curve type are provided by the vehicles. Each of the different braking curves of the same braking curve type of the particular vehicle is associated with one of the different train sequence point types.

Claims

1. A protection method for a rail network that is divided by track elements into track sections and on which vehicles can travel, the method comprising:

specifying different types of headway points; and

providing, by the vehicles, different braking curves of a same type of braking curve, and assigning each of the different braking curves of the same type of braking curve for a respective vehicle to a respective one of the different types of headway points;

wherein at least one braking target point, which is a danger point, forms a headway point of a first type of headway points, and a first braking curve of the respective vehicle is assigned to the at least one braking target point, which is a danger point, and the first braking curve of the respective vehicle does not allow the respective vehicle to slip over the at least one braking target point;

wherein at least one further braking target point, which is not a danger point, forms a headway point of a second type of headway points, a second braking curve of the respective vehicle is assigned to the at least one further braking target point, which is not a danger point, and the second braking curve of the respective vehicle allows the respective vehicle to slip over the at least one further braking target point; and

wherein the different braking curves of the same type of braking curve include the first braking curve and the second braking curve.

2. The protection method according to claim 1, which comprises specifying a track element being a switching device as a braking target point, which is a danger point.

3. The protection method according to claim 1, which comprises specifying a track element being a bumper as a braking target point, which is a danger point.

4. The protection method according to claim 1, which comprises specifying a braking target point, which is a danger point, with reference to a current position of a vehicle end of a stationary vehicle in a track section for a following vehicle.

5. The protection method according to claim 1, which comprises specifying a track element being a spring-loaded switching device as a further braking target point, which is not a danger point.

6. The protection method according to claim 1, which comprises specifying a current position of a vehicle end of a moving vehicle in a track section as a further braking target point, which is not a danger point, for a following vehicle.

7. The protection method according to claim 1, which comprises specifying a track element embodied as a fictitious double entry/exit element as a braking target point, which is not a danger point.
