Description
Technical field：
The present invention relates to a kind of car parking active safety system and its control method.
Background technology：
With the development of society, increasingly paying attention to the security of car, car all employs double-loop air brakes.
But still with the presence of some unsafe hidden danger, for example car, in starting, driver releases parking braking, service brake
Operating pressure do not reach again just, or even also have and slip by slope the danger of brakeless power.
The content of the invention：
The present invention is to provide a kind of car parking active safety system to solve the above-mentioned problems of the prior art
And its control method.
The technical solution adopted in the present invention has：A kind of car parking active safety system, including inflating pump, drier,
Four-loop protection valve, parking brake gas receiver, afterwards brake gas receiver, it is preceding braking gas receiver, brake pedal, parking magnetic valve, hand control valve,
Brake chamber and preceding brake chamber, one end of the drier are connected with inflating pump afterwards, and the other end is connected with four-loop protection valve,
Parking brake gas receiver, rear braking gas receiver and preceding braking gas receiver are connected with four-loop protection valve, brake pedal respectively with preceding braking
Gas receiver, braking gas receiver, preceding brake chamber are connected with rear brake chamber afterwards, parking magnetic valve air inlet and parking brake gas receiver phase
Even, gas outlet is connected with hand control valve, and manual valve air gate is connected with rear brake chamber.
Further, the parking magnetic valve is open type 2/2-way magnetic valve.
The present invention also provides a kind of control method of car parking active safety system, including
1) when preparing starting when car is in parking braking state, the controller of system is received from preceding braking gas receiver
With the pressure V of rear braking gas receiver；
2) if the pressure V of above-mentioned reception is more than the minimum operating pressure Vmin of service brake, parking magnetic valve not work
Make；
If 3) the pressure V of the reception is less than the minimum operating pressure Vmin of service brake, the controller control of system
Parking closed electromagnetic valve processed, parking braking continue to act on, until the pressure V of preceding braking gas receiver and rear braking gas receiver is more than most
Low operating pressure Vmin.
The present invention has the advantages that：The present invention is simple to operate, applied extensively, cost is relatively low, highly reliable.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention discloses a kind of car parking active safety system, including inflating pump 1, drier 2, four times
Road protection valve 3, parking brake gas receiver 4, rear braking gas receiver 5, preceding braking gas receiver 6, brake pedal 7, parking magnetic valve 8, manual control
Valve 9, rear brake chamber 10 and preceding brake chamber 11, one end of drier 2 are connected with inflating pump 1, the other end and four loop protections
Valve 3 is connected, and four-loop protection valve 3 is connected with rear braking gas receiver 5, preceding braking gas receiver 6 and parking brake gas receiver 4, brake pedal 7
It is connected respectively with preceding braking gas receiver 6, rear braking gas receiver 5, preceding brake chamber 11, rear brake chamber 10, parking magnetic valve 8 enters
Gas port is connected with parking brake gas receiver 4, and gas outlet is connected with hand control valve 9, and the gas outlet of hand control valve 9 is connected with rear brake chamber 10.
Parking magnetic valve 8 in the present invention is open type 2/2-way magnetic valve, and the magnetic valve has two gas ports, respectively
For：Air inlet, gas outlet.Air inlet is connected with parking brake gas receiver 4, and gas outlet is connected with hand control valve 9.When the controller in system
When controlling control parking 8 closing of magnetic valve of parking magnetic valve 8, parking braking air circuit is closed, and parking braking is worked.
Inflating pump 1, drier 2, four-loop protection valve 3, brake pedal 7, hand control valve 9, rear brake chamber in the present invention
10th, the operation principle of preceding brake chamber 11 is protected with the inflating pump in prior art microbus air braking system, drier, four loops
It is identical to protect valve, brake pedal, hand control valve, rear brake chamber, the operation principle of preceding brake chamber, therefore no longer the present invention is gone to live in the household of one's in-laws on getting married
State.
The control method of above-mentioned car parking active safety system, including
1) when preparing starting when car is in parking braking state, the controller of system is received from preceding braking gas receiver
The 6 and pressure V of rear braking gas receiver 5；
2) if the pressure V of above-mentioned reception is more than the minimum operating pressure Vmin of service brake, the not work of parking magnetic valve 8
Make；
If 3) the pressure V of the reception is less than the minimum operating pressure Vmin of service brake, the controller control of system
Parking magnetic valve 8 processed is closed, and parking braking continues to act on, until the pressure V of preceding braking gas receiver 6 and rear braking gas receiver 5 big
In minimum operating pressure Vmin.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
