A method and system for controlling a vehicle brake cylinder pressure

The present application discloses a method and system for controlling a vehicle brake cylinder pressure, to brake the received control command as a trigger signal, the detected current signal and the presence of the full penalty brake interlock brake interlock signal to any one of when the interlock signal, outputs a brake cylinder pressure corresponding to the interlock signal value; upon detecting two interlock signal do not exist, then the system using ECP operation state, the current brake cylinder pressure and the brake controlling a brake cylinder pressure corresponding to the command value determining the output value of the brake cylinder pressure. Compared Traditionally, the ECP system used in the present application the brake control transfer instruction mode electrical signals transmitted by a conventional compressed air into the transfer speed is no longer subject to the influence of the braking velocity, faster transmission; This application is a ECP system based on the operating state, the current brake cylinder pressure and the brake cylinder pressure and the brake control output value determining brake cylinder pressure corresponding to the command value, as compared to the conventional, the control accuracy is improved greatly.
