Abstract
A device and method for electromechanically braking rail vehicles use a brake system that includes a brake control unit configured to provide braking functions and output an actuation variable, a braking force unit configured to provide functions for generating a frictional braking force based on the actuation variable, a first braking path with braking functions that are active between control inputs by the brake system and the generation of a braking force, and a second braking path with braking functions that are active between control inputs by the brake system and the generation of a braking force.
Claims21
A brake system for a rail vehicle, the brake system comprising:
- a brake control unit configured to provide braking functions and to output a force actuating variable or an actuating variable;
- a braking force unit configured to provide functions for generating a frictional braking force based on the force actuating variable or the actuating variable;
- a first braking path including functions that are active between control inputs of the brake system and the generation of braking force;
- and
- a second braking path including 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 braking force unit is configured to receive a switching signal and, upon receiving a switching signal in the braking force unit, to switch from the first braking path to the second braking path, or to switch from the second to the first braking path.
A rail vehicle having a brake system having:
- a brake control unit configured to provide braking functions and to output a force actuating variable or an actuating variable;
