Abstract

A brake control device for a brake system of a rail vehicle, wherein the brake control device is designed to control at least one electromagnetic track brake device of the brake system on the basis of rail condition data. Also disclosed is a corresponding brake system, a rail vehicle, and a corresponding method.

First claim

The invention claimed is:

1. A brake control device for a brake system of a rail vehicle, the brake control device comprising:
at least one brake force sensor and/or brake torque sensor configured to measure the at least one brake force and/or brake torque at at least one brake device,
wherein the brake control device is designed to actuate at least one magnetic track brake device of the brake system irrespective of actuation of the at least one brake device based on rail state data and based on brake force and/or brake torque data of the at least one brake device,
wherein the at least one brake device is a different brake than the at least one magnetic track brake,
wherein the rail state data comprises adhesion data calculated by the brake control device based on data received from a plurality of pressure sensors, and
wherein the data received from the plurality of pressure sensors comprises data received from pressure sensors at two brake blocks and from a main pressure sensor at a main valve device.

2. The brake control device of claim 1 , wherein the brake control device is further designed to actuate the magnetic track brake device based on speed data.

3. The brake control device of claim 1 , wherein the rail state data comprises wheel slip data.

4. The brake control device of claim 1 , wherein the rail state data can be transmitted to the brake control device by an antiskid device.

5. The brake control device of claim 1 , wherein the rail state data relates to wheels which are arranged downstream of the at least one magnetic track brake device and/or a frictional component of the magnetic track brake device in the direction of travel of the rail vehicle.

6. The brake control device of claim 1 , wherein the brake control device is designed to deactivate the magnetic track brake device when predefined rail state conditions are reached.

7. The brake control device of claim 1 , wherein the rail state data comprises at least an adhesion and/or adhesion coefficient.

8. The brake control device of claim 1 , wherein the brake pressure and/or brake torque data relates to a pressure-operated service brake device.

9. The brake control device of claim 1 , wherein the brake force and/or brake torque data relates to the at least one brake device which is arranged downstream of the at least one magnetic track brake device and/or a frictional component of the magnetic track brake device in the direction of travel of the rail vehicle.

10. The brake control device of claim 1 , wherein the at least one magnetic track brake is configured to be activated by the brake control device to operate simultaneously with the at least one brake device.

11. A brake system for a rail vehicle comprising:
at least one magnetic track brake device, and
a brake control device designed to actuate the at least one magnetic track brake device irrespective of actuation of at least one other brake device of the brake system based on rail state data and based on brake force and/or brake torque data of the at least one other brake device,
wherein the rail state data comprises adhesion data calculated by the brake control device based on data received from a plurality of pressure sensors, and
wherein the data received from the plurality of pressure sensors comprises data received from pressure sensors at two brake blocks and from a main pressure sensor at a main valve device.

12. A rail vehicle comprising:
a brake system having at least one magnetic track brake device, the magnetic track brake device including a plurality of frictional components, and
a brake control device designed to selectively actuate the plurality of frictional components at the magnetic track brake device independent of actuation of at least one other brake device of the brake system based on rail state data and based on brake force and/or brake torque data of the at least the at least one other brake device,
wherein the plurality of frictional components are configured to be actuated separately from one another,
wherein the rail state data comprises adhesion data calculated by the brake control device based on data received from a plurality of pressure sensors, and
wherein the data received from the plurality of pressure sensors comprises data received from pressure sensors at two brake blocks and from a main pressure sensor at a main valve device.

13. A method for actuating at least one magnetic track brake device of a brake system of a rail vehicle comprising:
receiving rail state data at a brake control device;
receiving brake force and/or torque data of at least another brake device at the brake control device;
automatically adjusting a magnetic track brake device, while the at least another brake device continues to operate, based on the rail state data and the brake data;
receiving further rail state data and further brake force and/or torque data;
wherein in response to a determination that braking should continue based on the further brake force and/or torque data, the brake control device determines whether predefined rail state conditions have been reached based on the further rail state data and deactivates the magnetic track brake device,
wherein the rail state data comprises adhesion data calculated by the brake control device based on data received from a plurality of pressure sensors, and
wherein the data received from the plurality of pressure sensors comprises data received from pressure sensors at two brake blocks and from a main pressure sensor at a main valve device.
