An apparatus for controlling a brake device of a rail vehicle, the apparatus comprising:
- a characteristic curve changing device for varying a pressure characteristic curve of the brake device dependent on a friction characteristic of a brake pad type used in the brake device, wherein the characteristic curve changing device effects a vertical shift of pressure-speed characteristic curve along the pressure axis dependent on the friction characteristic, and
- a determining device for determining the friction characteristic based on a control signal, which indicates the selected brake pad type
- wherein the friction characteristic of the brake pad type is an average friction coefficient.
A brake system for a rail vehicle, having an apparatus controlling a brake device of the rail vehicle, the apparatus comprising:
- a characteristic curve changing device for varying a pressure characteristic curve of the brake device dependent on a friction characteristic of a brake pad type used in the brake device, wherein the characteristic curve changing device effects a vertical shift of pressure-speed characteristic curve along the pressure axis dependent on the friction characteristic, and
- a determining device for determining the friction characteristic based on a control signal which indicates the selected brake pad type
- wherein the friction characteristic of the brake pad type is an average friction coefficient.
