Abstract:
1. A brake system of a rail vehicle, the brake system comprising: a brake actuator which is assigned to a wheel or a wheel set and includes a brake disk and a brake lining which interacts with the brake disk to generate a braking force in response to a braking demand; at least one sensor device that measures a time profile of at least one variable, wherein the at least one variable is one of a wheel rotational speed, a wheel circumferential acceleration, a braking force, a braking torque and brake pressure, wherein the at least one variable represents fluctuations in friction conditions between the wheel or wheel set assigned to the brake actuator and a rail or fluctuations in friction conditions between the brake disk assigned to the brake actuator and the brake lining, wherein the at least one sensor device modulates and outputs a signal which is dependent on the at least one variable, a control device that receives the signal output from the at least one sensor device, wherein the control device adapts a braking force generated by the brake actuator as a function of a deviation of the at least one variable from a predefined or expected time profile of the at least one variable, wherein in response to a deviation that is greater than a permitted deviation at the brake actuator, the braking force at the brake actuator is increased and, for the purpose of compensation, a braking force at a further brake actuator with a deviation that is smaller than the permitted deviation is reduced resulting in the sum of the actual braking forces, of the brake actuator and the further brake actuator corresponding to an overall setpoint braking force corresponding to the braking demand.
