Brake control device for a braking system of a rail vehicle, braking system, rail vehicle and method for carrying out a state analysis of a rail vehicle

1. A brake control device for a braking system of a rail vehicle,

wherein the brake control device is connected to a sensor device for receiving vibration data,

wherein the brake control device identifies at least one periodic signal from the vibration data and stores comparison data based on the vibration data,

wherein the brake control device carries out a state analysis of the rail vehicle based on the comparison data and/or at least one periodic signal, wherein the brake control device carries out the state analysis while the rail vehicle is not being braked or while at least one brake device assigned to the sensor device is not activated, and

wherein the sensor device comprises at least one vibration-sensitive sensor for detecting a brake moment and/or a brake force exerted by a friction brake device.

2. The brake control device of claim 1 , wherein the brake control device compares, in the state analysis, data based on vibration data received from the sensor device with stored comparison data.

3. The brake control device of claim 1 , wherein the sensor device is assigned to at least one friction brake device.

4. The brake control device of claim 1 , wherein the brake control device is connected to at least one wheel rotation speed sensor.

5. The brake control device of claim 1 , wherein the brake control device carries out the state analysis based on line data which concern a route traveled by the rail vehicle.

6. The brake control device of claim 1 , wherein the brake control device establishes, in the state analysis, a derailment of at least one wheel based on a non-periodic signal from the sensor device.

7. A braking system for a rail vehicle with a brake control device, wherein the brake control device is connected to a sensor device for receiving vibration data,

wherein the brake control device identifies at least one periodic signal from the vibration data and stores comparison data based on the vibration data,

wherein the brake control device carries out a state analysis of the rail vehicle based on the comparison data and/or at least one periodic signal, wherein the brake control device carries out the state analysis while the rail vehicle is not being braked or while at least one brake device assigned to the sensor device is not activated, and

wherein the sensor device comprises at least one vibration-sensitive sensor for detecting a brake moment and/or a brake force exerted by a friction brake device.

8. A rail vehicle with a braking system comprising a brake control device, wherein the brake control device is connected to a sensor device for receiving vibration data,

receiving, by a brake control device, vibration data which are transmitted by a vibration-sensitive sensor device;

identifying at least one periodic signal in the vibration data by the brake control device;

storing comparison data based on the vibration data by the brake control device; and

performing a state analysis of the rail vehicle by the brake control device based on the comparison data and/or the at least one periodic signal, wherein the state analysis is performed while the rail vehicle is not being braked or while at least one brake device assigned to the sensor device is not activated, and

wherein the sensor device comprises at least one vibration-sensitive sensor for detecting a brake moment and/or a brake force exerted by a friction brake device.
