During work, first open electric air pump 3, make air tank 4 air pressure reach normal operating air pressure；Direct current 12V power supply gives electricity
Sub-control unit is powered, and ignition switch closes provides ignition signal to electronic control unit；Open wheel drive motors, wheel turns
Dynamic, four wheel speed sensors provide tach signal to electronic control unit:
Not stepping on brake pedal, electronic control unit is not received by brake signal, and electronic control unit does not gives four three
Three-way magnetic valve is powered, and 3-position-3-way solenoid valve is in diagram UNICOM state, air tank air gauge display gas receiver air pressure, pipeline
Air gauge and brake chamber air gauge are all shown as 0.
Stepping on brake pedal, electronic control unit receives brake signal.During beginning, vehicle wheel rotational speed is very fast, Electronic Control list
Meta-analysis, judging the now non-locking of wheel, electronic control unit is not powered to 3-position-3-way solenoid valve, at 3-position-3-way solenoid valve
In diagram UNICOM state, brakes is in conventional brake state, and brake control valve communicates with brake chamber pipeline, air tank gas
Pressure table display gas receiver air pressure, pipeline air gauge and brake chamber air gauge all show brake pressure, and two pressure are equal and with system
Dynamic pedal travel increases, its value also synchronizes to increase.
Continuing to step on brake pedal, vehicle wheel rotational speed is slack-off, and when vehicle wheel rotational speed drops to a certain value, electronic control unit divides
Analysis, judge now wheel will locking, electronic control unit leads to small area analysis to 3-position-3-way solenoid valve, at 3-position-3-way solenoid valve
In intermediate orientation, three passages are all spaced from each other, i.e. brake control valve is all spaced from each other with brake chamber pipeline and air,
Now, air tank air gauge still shows that gas receiver air pressure, pipeline air gauge show the pressure corresponding with brake-pedal travel；As
Continuing to strengthen brake-pedal travel, pipeline air gauge air pressure continues to raise but brake chamber air gauge pressure will keep constant, anti-
Only wheel lock up.Continuing to decline at vehicle wheel rotational speed, electronic control unit leads to big electric current, 3-position-3-way electricity to 3-position-3-way solenoid valve
Magnet valve is in lower end position state, and brake chamber communicates with air, brake chamber release partial gas pressure, prevents wheel from embracing further
Extremely, now, air tank air gauge still shows that gas receiver air pressure, pipeline air gauge show the pressure corresponding with brake-pedal travel
Power, but brake chamber air gauge pressure will decline.After brake chamber air pressure declines, vehicle wheel rotational speed will rise, electronic control unit
To 3-position-3-way solenoid valve power-off, 3-position-3-way solenoid valve returns diagram UNICOM state, and brake chamber air pressure increases again, increases
Brake efficiency.
During running brake hard, electronic control unit constantly receives wheel speed signal, judges wheel by analyzing, calculating
Kinestate, and control 3-position-3-way solenoid valve and be in different duties, so that wheel is in all the time close to locking
State, to improve braking ability and the riding stability of automobile.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
