图片内容介绍
From the brake force calculation diagram, we can see that based on the brake deceleration demand request from master controller or ATO system, the train mass calculated from the real ASP value and the relationship, the total brake force will be calculated by the Gateway Valve.
Electrical dynamic brake force will be applied firstly, and feedback the real ED brake force to Gateway Valve through MVB train BUS, and then Gateway Valve will calculate the pneumatic brake force to meet the total required brake force. After that, Gateway Valve will distribute the EP friction brake force onto individual bogies equally under the adhesion limit of each bogie.
The local brake control will output the brake control pressure to the corresponding bogie mounted friction brake unit to realize the friction brake force based on the request from gateway valve through CAN internal BUS.
For emergency brake, the brake force is automatically applied based on local bogie’s load signal (ASP value).
COF value for service brake and emergency brake application and the relationship between ASP to emergency brake cylinder pressure will be verified and fixed during type test.
