METHOD AND SYSTEM FOR CONTROL OVER PNEUMATIC BRAKES OF RAILWAY ROLLING STOCK Russian patent published in 2020 - IPC B60T8/172 B61L3/12 

FIELD: rail transport.

SUBSTANCE: control method of pneumatic brakes of railway rolling stock, characterized by that: determining the track coordinate, when it is achieved, it is necessary to reduce speed of railway rolling stock; determining the speed of railway rolling stock, which must be in previously determined track coordinate; determining friction coefficient of shoe friction coefficient against program speed; determining a braking coefficient; determining the time during which the braking force acquires the maximum value; determining the time during which pneumatic brakes are released; determining the coordinate of the path in which pneumatic braking is to be started, and the coordinate of the path in which the pneumatic brakes are to be started; when reaching the path coordinate, in which it is necessary to start braking, command to start braking is transmitted to rolling stock control system; when the track coordinate is reached, in which it is necessary to start the pneumatic brakes release, the command to release pneumatic brakes is sent to the rolling stock control system. Machine-readable data medium contains instructions, the execution of which implements execution of the brake control method.

EFFECT: technical result is increase in rolling stock speed and stop control accuracy.
