Along with the development of auto-domain, traffic safety more and more receives publicity.Present automotive airbag has become the standard configuration of most vehicle, and in various traffic accident, actv. protects the safety of chaufeur and member, and is updating in process.
But in the collision process of vehicle, the damage of vehicle and pedestrian and opponent vehicle is but always inevitable, such as present vehicle, in order to alleviate the injury to pedestrian, has started bumper/spoiler, the fender guard of saying vehicle, and it is soft as much as possible that driving engine office lid and case cover do.Although the object of well protection pedestrian can be reached; but also result in the decline of the intensity of vehicle itself; at vehicle and other vehicle; such as heavy-duty vehicle; suffer heavy losses in the collision of passenger vehicle and train; and due to the crumple of vehicle structure, extruded the space of member in car greatly, and then caused the generation of tragedy.
Can air bag in vehicle be mounted at outside vehicle as crossed, in collision, front opening occur, namely can play the effect of protection pedestrian, also can protect the vehicle of one's own side and the other side simultaneously, the loss of vehicle is dropped to minimum.
When collision happens, the a lot of because have of final collision result can be affected, traditional account form is all judge with the speed of vehicle, lack the consideration to other factors, the weight of such as car body, this just must cause the deficiency estimated the energy produced during collision happens, under being applied in outer air bag situation, likely because air bag opens amplitude not quite, cause the damage of vehicle.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of outer gas-bag system of automobile changing speed of expansion according to automobile momentum of development, have:
The collision perception unit of perception vehicle and obstacle distance;
The speed of a motor vehicle acquiring unit communicated to connect with vehicle bus, obtains the current speed of a motor vehicle;
The car weight acquiring unit communicated to connect with vehicle bus, obtains the quality of current car body;
Processing unit, the vehicle speed signal that the collision thing Distance geometry speed of a motor vehicle acquiring unit that the collision perception unit described in reception transmits is uploaded, calculating the time that collision occurs, when reaching regular hour threshold value, sending actuation signal; Simultaneously according to the quality of the described speed of a motor vehicle and car body, calculate the momentum of current car body;
Blast start unit and outer air bag: blast start unit receives the actuation signal that described processing unit issues, and outside airbag aeration, opens outer air bag;
Each described outer air bag has multiple air-filled pore, each air-filled pore and a start unit UNICOM of exploding, i.e. a corresponding multiple blast start unit of outer air bag; Described processing unit determines according to Current vehicle momentum the quantity that the blast start unit that each air bag is corresponding starts; Momentum is larger, and the blast start unit of startup is more, and accordingly when momentum is less, it is fewer that blast start unit starts quantity.
Described blast start unit and outer air bag are at least fixed on vehicle front bumper, car door and rear bumper.
Described collision perception unit comprises the car radar be arranged on vehicle front bumper, car door and rear bumper.
Described collision perception unit, speed of a motor vehicle acquiring unit, processing unit and blast start unit are communicated to connect by vehicle bus.
Described blast start unit, comprises the base of fixing vehicle body, is fixed on the multiple blast generating boxes arranged in modularization on base.
Owing to have employed technique scheme, a kind of outer gas-bag system of automobile changing speed of expansion according to automobile momentum provided by the invention, by arranging external omnidirectional's radar and corresponding calculating unit, the air bag of vehicle in the front opening outside of generation external impact can be ensured, reduce the suffered damage of automobile, adopt modular exploding unit simultaneously, can all open, also can open according to the large fraction of the momentum of current car body.The technology maturation adopted, is extremely suitable for promoting on a large scale and using.
