Parking relay valve 13 is then returned to, and through parking relay valve 13 and the two-position three way return electron parking valve 9.Main brake valve 8
Locellus 17 before another output terminal distributes to two through a quick release valve 15.
Commercial car electronic parking system according to the invention can realize i.e. static basic function and dynamic parking and release, face
When parking function, emergency brake function, release function of starting to walk, stop working control model and uphill starting function.
As shown in the figure：Static state/dynamic parking function replaces traditional hand valve with parking switch, and pull-up EPB switches are table
Show and pull the hand brake, under push away EPB switch represent release parking brake.When pulling up EPB switches, ECU can say the word electron parking valve, allow electronics
The parking solenoid valves of parking valve are primary, and the air pressure of control mouth of parking relay valve is allowed to be arranged from the exhaust outlet of electronic parking valve
Fall so that the air pressure of spring cylinder exhausts, and achievees the purpose that parking.Under when pushing away EPB switches, ECU can then say the word electron parking
Valve, the solenoid valves for allowing release are primary, and the air inlet of air pressure from electronic parking valve of gas receiver is allowed to enter delivery outlet, enter
The control mouth of parking relay valve so that the delivery outlet of parking relay valve has output pressure to transport to spring cylinder, achievees the purpose that driving.
Emergency brake：When vehicle needs emergency brake, when speed is more than such as 7km/h, priority acccess control electronic parking
The temporary parking solenoid valve of valve carries out service brake, and after speed is less than 7km/h, ECU can control the parking electricity of electronic parking valve
Magnet valve carries out parking braking, and vehicle will not sideslip or whipping.
Starting release：When driver drives, such as forget RELEASE PARKINGBRAKE, system when detecting speed, ECU can say the word to
Electronic parking valve, unclamps parking brake automatically.The process is different from manual parking, is automatic parking.
It flames out and stop：When vehicle stall, such as non-parking, ECU can say the word electron parking valve, automatic parking.The mistake
Journey is different from manual parking, is automatic parking.
Uphill starting function：Realize ramp miscellaneous function.Pass through the speed signal of collection vehicle, gear signal, throttle letter
Number, engine torque signal and ramp angles signal, according to different situations, in different gasoline throttle angles, ECU, which makes, sentences
It is disconnected, parking switch is unclamped automatically, realizes smoothly starting.
In order to which the superiority of EPB systems according to the invention is seen more clearly, first by EPB systems according to the invention with

It is GB 12676-2014 that the system, which performs standard,《Commerial vehicle and the requirement of trailer brake system technology and experiment side
Method》Standard requirement.The product is independently researched and developed by my company scientific and technical personnel.
Commercial car electronic parking system according to the invention is that Rui Li groups input and tissue are researched and developed, and auspicious stand is China
Most of main engine plants (space lead to, greatly fortune, Shan vapour, Yangtze River, Yangze river and Huai river, a vapour etc.) supplier.Needed for EPB according to the invention
The resources such as processing can be extended on the basis of original, the parts of use use import except the parts thereof in controller
Outside part, remaining electronic parking valve, turn-knob valve, switch are all using home part, this Project Product degree domestic height.
8,500,000 yuan of this project total investment quota, according to market information and the development trend in automobile future, future market is to electronic
The demand of air compressor machine will be more than 100,000 sets or more.According to my company's comprehensive strength, we have examined during trial production
Having considered production capacity, tooling configuration, device configuration, staff training etc. influences the factor of productivity, by the life for producing 3000 sets per year
Production capacity power estimated, 4800 yuan of this product totle drilling cost, 7000 yuan of average sales price, annual 21000000 yuan of sales volume, return of investment
Rate is 66%, profit and tax investment ratio 90.8%, 1.52 investment payback times, remarkable benefit.
This project EPB systems, which increase, flames out and stop function, and during vehicle stall, even if having forgotten to pull the hand brake, system can be automatic
Complete parking；Increase starting release function, during vehicle start, driver has forgotten RELEASE PARKINGBRAKE, and parking braking can also automatically terminate；Increase
Uphill starting function is added, vehicle, will not rollback in uphill starting；Increase temporary parking function, waiting traffic lights or
It will not have to step on brake always again when being temporary parking, it is therefore prevented that the foot of driver generates fatigue, reduces and drives intensity, reduces thing
Therefore generation.Temporary parking function can also reduce the discharge of parking chamber air pressure simultaneously, reduce the demand of compressed air, reach section
The effect of energy.So that vehicle is more intelligent, easy, safety, the generation of accident is reduced.
