Abstract

The invention provides a railway vehicle brake fusion control system and method. The railway vehicle brake fusion control system comprise a bullet train control units and trailer control units. Each bullet train control unit comprises a bullet train fusion controller which receives a traction force instruction and carries out traction force calculation according to a preset first condition, or receives a brake instruction and carries out total brake force calculation according to the brake instruction, calculates electric brake force and first friction brake force according to a preset secondcondition, a traction system executing device used for executing traction operation according to traction force or executing brake operation according to the electric brake force, and a first frictionbrake driving control and executing device used for executing friction braking operation according to the first friction brake force. Each trailer control unit comprises a trailer fusion controller for receiving a brake instruction and calculating second friction brake force according to a preset third condition, and a second friction brake driving control and execution device for executing friction brake operation according to the second friction brake force. Therefore, the fusion control over traction and brake is completed.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a rail vehicle brake fusion control system and method. Background technique [0002] The current traction control system and brake control system of rail transit vehicles are two independent systems, each with its own independent controller. When the vehicle is braking, it will adopt the hybrid braking method of electric braking and friction braking to reduce the wear of the brake shoes. Generally, electric braking is used first, and the insufficient part of electric braking is supplemented by friction braking, so traction The system and the braking system will be controlled in cooperation. At present, the controllers between the two systems exchange information through the network. Due to the delay in the data transmission process, the hybrid braking cannot be accurately executed, which affects the braking response speed, resulting in electric braking and friction bra...
