  • Pressure Control Method and Pressure Control Device for Braking Cylinder of Rail Vehicle, And Rail Vehicle
    Publication number: 20230219548
    Abstract: Disclosed are a pressure control method and a pressure control device for a braking cylinder of a rail vehicle, and the rail vehicle. The method includes the following steps: acquiring the air charge-release volume of the braking cylinder of the rail vehicle and the air flowrate of the braking cylinder; determining the charge-release duration according to the air charge-release volume of the braking cylinder and the air flowrate of the braking cylinder, and controlling the charge-release working duration of the air charge-release solenoid valve according to the air charge-release duration; when the working duration of the air charge-release solenoid valve reaches the charge-release duration, acquiring the predictive pressure of the braking cylinder, and controlling the working state of the air charge-release solenoid valve according to the predictive pressure.
