Method for controlling a compressed air brake device of a rail vehicle in the case of forced, emergency or emergency braking

摘要

The invention relates to a method for controlling a controlled electro-pneumatic brake device (2) with brake pressure control and an unregulated brake pressure control device (4) for generating an unregulated brake pressure and at least one pneumatic brake actuator (16) having compressed air braking device of a rail vehicle in the case of a forced, rapid or emergency braking. The invention provides that, in response to a signal for triggering forced, rapid or emergency braking, a) the controlled electro-pneumatic brake device (2) and the uncontrolled brake pressure control device (4) are activated simultaneously and b) a first value (10) for the brake pressure generated by the controlled, electro-pneumatic brake device (2) or a first value (10) for a pilot pressure representing this brake pressure and a second value (12) for the brake pressure generated by the unregulated brake pressure control device (4) or a second value (12) are compared with one another for a pilot pressure representing this brake pressure, this comparison taking place by the action of the first value (10) and the second value (12) on mechanical components of an exclusively pneumatic-mechanical comparison device (14), and c) depending on this comparison, a brake pressure based solely on the first value (10) or out is finally driven on the basis of the second value (12) or on the basis of the first value (10) and the second value (12) in the at least one pneumatic brake actuator (16).
