Abstract
The utility model relates to a device for controlling a safe air bag on a vehicle, in particular to a vehicle air bag control system. The system comprises an air bag ECU and a gas generator which is controlled by the air bag ECU and used for inflating an air bag and further comprises a cutter controlled by the air bag ECU and used for cutting an air bag stretching belt. Due to additional arrangement of the cutter, when vehicles collide, the air bag ECU controls the cutter to cut, so after being ignited, the air bag has a large size and pressure, and safety protection for passengers with a large figure is improved than that of a traditional ignition mode.
Description
Technical field
The utility model relates to a kind of device that the safety air bag being arranged on vehicle is controlled, and relates in particular to a kind of Vehicular air bag control system.
Background technology
In the airbag structure of existing front, its form is comparatively single, comprise utricule more, be arranged on the drawstring on utricule, and be arranged on the deflation hole on utricule, and by the setting of drawstring, the volume can actv. control utricule launching, and by the setting of deflation hole, can control the pressure of gas in utricule.In the control system of air bag; mainly to control gas generator by air bag ECU utricule is inflated; make vehicle in the time of collision; according to car speed information; to obtain value of vehicle acceleration to judge whether to reach the igniting threshold values of air bag; in the time reaching igniting threshold values, air bag point is quick-fried, and then realizes the protection to occupant.When above-mentioned air bag, to put quick-fried logic simple, makes vehicle at different collision velocitys, or passenger is while varying in size, all adopts the quick-fried form of same point, can not realize the safer protection to passenger.
Utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of Vehicular air bag control system with multiple airbag-releasing form, and it has further improved passenger's safety.
For achieving the above object, Vehicular air bag control system of the present utility model, comprises air bag ECU, is controlled and gas generator to airbag aeration by air bag ECU, also comprises the cutter of being controlled by air bag ECU, air bag drawstring is cut off.
By setting up cutter, make vehicle in when collision, by air bag, ECU cuts off cutter, so that air bag point has larger volume and pressure after quick-fried, quick-fried formal at traditional point, has strengthened the safety guard-safeguard to the larger occupant of build.
As to improvement of the present utility model, also comprise be connected with air bag ECU, to detecting device that in vehicle running state and car, member condition detects.By setting up detecting device, can make air bag ECU comprehensively judge according to the motoring condition of vehicle and passenger's state, to control the pressure size in volume or the air bag of air bag, further strengthen the applicability of air bag, improve occupant's safety.
As the restriction to aforesaid way, described detecting device comprises the car speed sensor that car speed is detected.By car speed is detected, to judge that vehicle is collision under high-speed or the collision under low speed in the time bumping, so that air bag ECU is put quick-fried volume and pressure according to different speed control air bags.
As the restriction to aforesaid way, described detecting device comprises the position detector that vehicle seat position is detected.By position detector, realize the detection to passenger's volume size, so that air bag ECU is put quick-fried volume and pressure according to different occupant's volume control air bags.
As the restriction to aforesaid way, described position detector is position transduser or the cushion sensor OCS arranging on the seat.
As the restriction to aforesaid way, described detecting device comprises setting weight sensor on the seat.Set up weight sensor, can detect occupant's weight, realize passenger's type (child, Ms or man) is judged, so that air bag ECU is put quick-fried volume and pressure according to different passenger type control air bags.
In sum, adopt the technical solution of the utility model, increased air bag and put quick-fried form, more can be adapted to different vehicle form states and passenger's state so that air bag puts when quick-fried, further improved taking advantage of of passenger and driven safety.
Brief description of the drawings

Fig. 1 is the connection structure block diagram of the utility model embodiment;
Fig. 2 is the annexation sketch of Fig. 1 in the time being combined with air bag;
Fig. 3 is the annexation sketch of Fig. 2 in the time cutting off air bag drawstring.
In figure:
1, utricule; 2, air bag drawstring; 3, deflation hole; 4, air bag ECU; 5, gas generator; 6, cutter; 7, detecting device; 701, car speed sensor; 702, position detector; 703, weight sensor.
Detailed description of the invention
Existing Vehicular air bag structure, as shown in Figure 2, it mainly comprises utricule 1, be arranged on the air bag drawstring 2 on utricule 1, and be arranged on the deflation hole 3 on utricule 1, and by the setting of air bag drawstring 2, the volume can actv. control utricule 1 launching, and by the setting of deflation hole 3, can control the pressure of utricule 1 interior gas.
The Vehicular air bag control system that the present embodiment relates to, that the existing airbag structure based on is as above controlled, by Fig. 1 in conjunction with shown in Fig. 2, it comprises air bag ECU4, is controlled and gas generator 5 to airbag aeration by air bag ECU4, also comprises the cutter 6 of being controlled by air bag ECU4, air bag drawstring 2 is cut off.Cutter 6 can adopt the conventional controllable device with cutting knife, by the cut-out to air bag drawstring 2, can change the expanding volume of utricule 1.
The detecting device 7 that member condition detects in the signal input part of air bag ECU4 is also provided with vehicle running state and car, the detecting device 7 in the present embodiment comprises car speed sensor 701, position detector 702 and weight sensor 703.Wherein, car speed sensor 701 is for Vehicle Speed is detected, and the information of detection is sent to air bag ECU4; Position transduser 702 is mounted on seat, and it detects for the position to seat, to judge the occupant's volume on seat, can adopt installation position transduser or cushion sensor OCS on the seat; Weight sensor 703 is same to be arranged on the seat, for the drive and passengers weight on seat is detected, and the weight information of detection is issued to air bag ECU, according to this weight information, air bag ECU judges occupant's type, also can binding site sensor, occupant's type is comprehensively judged.
While protecting the occupant of small volume in collision happens; signal is sent to air bag ECU by position transduser or OCS; weight sensor can detect occupant's weight simultaneously; in judging occupant's volume, judge occupant's type, now; air bag ECU does not cut off air bag drawstring; and control deflation hole 3 exhausts, volume and the internal pressure of utricule 1 are less, are conducive to protect the occupant of small volume.
In the time of vehicle collision, car speed sensor 701 detects vehicle speed signal, when air bag ECU judges the collision of vehicle under low speed according to vehicle speed signal, air bag drawstring do not cut off or time delay after cut off, and then make the pressure in utricule less, be conducive to the protection to occupant.
In the time that air bag ECU judges vehicle in high-speed crash according to vehicle speed signal; air bag ECU controls cutter 6 and cuts off air bag drawstring; control not exhaust of deflation hole simultaneously; make the volume of pressure in utricule and utricule larger; its state as shown in Figure 3, has been realized the more effectively protection to occupant under high-speed crash.
While protecting large build occupant in collision happens; seat position information is sent to air bag ECU by position transduser; air bag ECU controls cutter and cuts off air bag drawstring; not exhaust of deflation hole; make the volume of pressure in utricule and utricule larger, realized the more effectively protection to large build occupant.
