Brake system and braking method for rail vehicles

A rail vehicle having a brake system that includes:

• a brake control unit configured to provide braking functions and to output a force actuating variable;
• an actuator control unit configured to provide functions for generating a frictional braking force, based on the force actuating variable, and to output an actuating variable;
• a braking force unit configured to provide functions for generating a frictional braking force based on the actuating variable;
• a first braking path which includes functions that are active between control inputs of the brake system and the generation of braking force;
• and
• a second braking path which includes functions that are active between control inputs of the brake system, or when predetermined brake system state variables are present, and the generation of braking force,
• wherein the brake control unit is configured to provide braking functions of the first braking path and the second braking path;
