Abstract

A brake control device for a brake system for a rail vehicle, the brake system having at least one adhesion-type friction brake device. The brake control device receives brake actuation data, which are assigned to the at least one adhesion-type friction brake device, from a brake actuation sensor device of the brake system. The brake control device receives brake action data, which are assigned to the at least one adhesion-type friction brake device, from a brake action sensor device of the brake system, and to cause the adhesion-type friction brake device to effect a braking process, and to monitor and assign brake actuation data and brake action data to each other during a braking process. Also disclosed is a brake system, a rail vehicle and a method for operating a brake system.
