Abstract

The embodiment of the invention provides a rail vehicle brake control method and device. The rail vehicle brake control method includes the steps that a deceleration instruction is received and comprises target deceleration; first brake force is applied to a rail vehicle and is preset corresponding to the target deceleration; real-time deceleration of the rail vehicle is measured; second brake force is determined according to the difference of the real-time deceleration of the rail vehicle and the target deceleration and the first brake force; the second brake force is applied to the rail vehicle. By means of the method and device, brake force needing to be applied can be accurately determined when the total load information of the rail vehicle can not be obtained through displacement and pressure of a spring material on a bogie.

Description

technical field [0001] The invention relates to automatic control technology, in particular to a rail vehicle braking control method and device. Background technique [0002] With the development of rail vehicle technology, rail vehicles are becoming the first choice for more and more passengers to travel. During the running of rail vehicles, due to frequent passengers getting on and off the train, the total load of rail vehicles is constantly changing. In order to provide passengers with more For a comfortable rail vehicle driving experience, the braking control system of rail vehicles needs to provide more accurate braking force. [0003] An existing method for calculating the braking force that needs to be applied is: by collecting load information according to the change of the displacement and pressure of the spring on the bogie of the rail vehicle, the braking system of the rail vehicle calculates the braking force that needs to be applied according to the load informa...
