Abstract
A method controls a compressed-air braking device of a rail vehicle in the case of automatic, quick, or emergency braking, said compressed-air braking device having a controlled electropneumatic braking device having brake pressure control, an uncontrolled brake pressure control device for producing an uncontrolled brake pressure, and at least one pneumatic brake actuator. In response to a signal to trigger automatic, quick, or emergency braking, the controlled electropneumatic braking device and the uncontrolled brake pressure control device are activated simultaneously and a first value for the brake pressure produced by the controlled electropneumatic braking device or a first value for a pilot control pressure representing the brake pressure and a second value for the brake pressure produced by the uncontrolled brake pressure control device or a second value for a pilot control pressure representing the brake pressure are compared with each other.
