Abstract

A brake control device for a brake system of a rail vehicle, wherein the brake control device detects strain during a braking process on at least one friction brake device actuated during the braking process, the brake control device further stores wear data based on the detected strain in a memory device. Also disclosed is a brake system for a rail vehicle having such a brake control device, a rail vehicle having such a brake system and/or such a brake control device, and a method for operating a brake control device for a brake system of a rail vehicle.

Claims

1. A brake control device for a brake system of a rail vehicle, which determines a load of at least one friction brake device operated during a braking process;

wherein the brake control device is additionally stores wear data based on the determined load in a memory device.

2. The brake control device of claim 1, wherein the brake control device determines the load of a plurality of friction brake devices during a braking process and to stores wear data for each of the friction brake devices, which are each assigned to the corresponding friction brake device.

3. The brake control device of claim 1, wherein the brake control device actuates the brake system based on wear data.

4. The brake control device of claim 3, wherein the brake control device actuates a plurality of friction brake devices asymmetrically based on the wear data.

5. The brake control device of claim 1, wherein the brake system is a pneumatic brake system which has at least one pneumatically operable friction brake device.

6. The brake control device of claim 1, wherein the brake control device emits a signal based on the wear data which contains maintenance information relating to the at least one friction brake device.

7. The brake control device of claim 1, wherein the brake control device is connected to a sensor device, which enables data to be transmitted to the brake control device, based on which the brake control device determines the load.

8. A brake system for a rail vehicle having a brake control device as claimed in claim 1.

9. A rail vehicle having a brake system as claimed in claim 8 and/or a brake control device as claimed in claim 1.

10. A method of operating a brake control device for a brake system of a rail vehicle, the method comprising:

determining, using the brake control device, a load of at least one friction brake device of the brake system actuated during a braking process; and

storing, using brake control device, wear data based on the determined load.
