When normal brake application, using electric braking signal or gas brake signal as transmission braking instruction, electric braking signal is pedal 1
Master instruction, electric braking signal input the first brake monitor, and gas brake signal is divided to two-way to be separately connected by two the first shuttle valves 2
Into two the first brake execution units, the gas circuit of the first braking bridge module controls input port.When electric braking signal is effective, the
One brake monitor identifies that braking mode is normal brake application, calculates and distributes through brake force, exports brake pressure adjustment signal, point
Two-way is input to two first braking bridge modules, controls that two first braking bridge modules carry out brake pressure adjustings and output is to the
One brake chamber realizes control for brake.
Electric braking signal is transmitted to the second brake monitor even hung in brake unit by the first brake monitor simultaneously,
Second brake monitor is identical as the structure and working principle of the first brake monitor, and the second brake monitor controls two second
Brake execution unit completes the normal brake application for even hanging brake unit.
When electric braking Signal Fail, pedal 1 controls two first using gas brake signal as transmission braking instruction respectively
It brakes bridge module to carry out brake pressure adjusting and export to two the first brake chambers, realizes control for brake.Due to even hanging braking
Gas circuit between unit and two main brake units is connected to, so gas brake signal also while respectively controls two second brakings
Bridge module carries out brake pressure adjusting and exports to two the second brake chambers, realizes control for brake.
When electric braking Signal Fail, gas brake signal comes into force, and guarantees the normal service brake of vehicle.
When triggering the first external trigger, the dynamic signal of the first external trigger output electrical system to the first brake monitor,
First brake monitor identifies that braking mode is emergency braking, acquires each wheel speed, empty spring pressure in real time, situation of remote etc. is simultaneously located
Reason is calculated emergency braking vehicle brake force and carries out braking force distribution calculating, the first EP valve is inputted in the form of electric braking signal
Group, the first EP valve group of control carry out corresponding emergency braking control pressure and adjust, and the control pressure of the first EP valve group output is through two
A first shuttle valve 2 reaches two first braking bridge modules, and because emergency braking all uses air-pressure brake, brake force should be current
Maximum braking force under vehicle load, therefore pressure of the emergency braking after two the first EP valve groups are adjusted, when being greater than normal brake application
The control pressure of control for brake main valve output.When triggering emergency braking, the pressure exported through two the first shuttle valves 2 should be first
The emergency braking control pressure that EP valve group exports after adjusting, it is multiple which controls two first braking bridge modules progress pressure
Now amplify and be input to brake chamber with gas circuit, realizes emergency braking.
First EP valve group is independent automatically controlled proportional pressure valve group, and air pressure adjustment is mainly by the first brake monitor
It exports emergency braking electric braking signal and carries out pressure adjusting, when the first electric braking Signal Fail, the first EP valve group has bypass
Control pressure supplement, Bypass Control air pressure are set as the control pressure of brake force needed for meeting the fully loaded maximum emergency braking of vehicle.
It is identical when principle is with the first external trigger of triggering when triggering the second external trigger.
Each ABS solenoid valve is connected on the braking pressure delivery outlet of each braking bridge module between brake chamber input port respectively
Air pipe on.Each ABS solenoid valve is controlled by corresponding brake monitor, and by the first brake monitor or the second control for brake
The slip rate of all wheels of device real-time detection.When driving, when system detection to wheel has skidding and locking is inclined to, meeting
It controls corresponding ABS solenoid valve to carry out filling exhaust event, guarantees that the slip rate of all wheels is consistent, realize the braking of braking system
Stability.
The braking control system can internal system progress multiaxis extension, i.e. the first brake execution unit and the second braking execution
Unit can be for one or multiple, and the first brake execution unit and the second brake execution unit in the present embodiment are
Two.
Even hanging brake unit can be one or more, and it is one that brake unit is hung by the company in the present embodiment.Even hang braking
Unit carries out even extension by bus, and brake unit is hung by two main brake units by the companies of being transmitted to such as various brakings manipulation information, even
It hangs brake unit and on-position information etc. is fed back into main brake unit, the company of realizing hangs between brake unit and main brake unit
Coordination match control for brake.Main brake unit can by another road bus and vehicle central control unit and other mobile units into
Row communication, such as receives electric braking feedback information, receives the control for brake instruction etc. that vehicle central control unit issues.Even hang braking
Unit can realize two-way manipulation, manipulate unit based on the main brake unit on vehicle heading, the gas control pressure from pedal 1
By piping connection to brake unit is even hung, guarantee even to hang brake unit when electric control braking fails, gas control mode can normally rise
