Abstract
The invention discloses an external airbag system for automobiles. The external airbag system comprises a collision sensing unit sensing the distance between a vehicle and an obstacle; a vehicle speed acquiring unit which is connected with a vehicle bus in a communication manner, a processing unit, an explosion start unit and an external airbag, wherein the vehicle speed acquiring unit acquires the current vehicle speed; the processing unit receives an obstacle distance transmitted by the collision sensing unit and vehicle speed signals uploaded by the vehicle speed acquiring unit, and calculates collision occurring time, and when a certain time threshold is reached, start signals are sent out; the explosion start unit receives the start signals sent by the processing unit, and the external airbag is inflated to be started. An external all-direction radar and a corresponding calculation unit are arranged, so that it is guaranteed that the external airbag can be started before external vehicle collision occurs. Therefore, damage to the vehicle is reduced and hurt to passersby can be reduced. The technique adopted by the external airbag system is mature and reliable and is very suitable for a wide range of popularization and use.
Description
Technical field
The present invention relates to the outer gas-bag system of a kind of automobile.
Background technology
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.
Summary of the invention
The present invention is directed to the proposition of above problem, and the outer gas-bag system of a kind of automobile 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;
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;
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.
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.
Collision perception unit, speed of a motor vehicle acquiring unit, processing unit and blast start unit are communicated to connect by vehicle bus.
Owing to have employed technique scheme, the outer gas-bag system of a kind of automobile 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, also can reduce the injury to passerby simultaneously.The technology maturation adopted is reliable, is extremely suitable for promoting on a large scale and using.
Accompanying drawing explanation
In order to the technical scheme of clearer explanation embodiments of the invention or prior art, introduce doing one to the accompanying drawing used required in embodiment or description of the prior art simply below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is module diagram of the present invention
Detailed description of the invention
For making the object of embodiments of the invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear complete description is carried out to the technical scheme in the embodiment of the present invention:
As shown in Figure 1: the outer gas-bag system of a kind of automobile, mainly comprises: the collision perception unit of perception vehicle and obstacle distance; The speed of a motor vehicle acquiring unit communicated to connect with vehicle bus, obtain the current speed of a motor vehicle and processing unit, the vehicle speed signal that the collision thing Distance geometry speed of a motor vehicle acquiring unit that collision perception unit described in reception transmits is uploaded, calculate the time that collision occurs, when reaching regular hour threshold value, send actuation signal; 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.
The explosion type starter gear adopted, can ensure that safety air bag just can launch completely before colliding, and decreases the damage of vehicle self to the full extent.
Further, described blast start unit and outer air bag are at least fixed on vehicle front bumper, car door and rear bumper.As long as there is the danger of collision in vehicle direction, the air bag in all the other directions is just all opened, and drops to minimum by the loss of vehicle.
In order to ensure the sensitivity to impact detection, as a preferably embodiment, described collision perception unit comprises the car radar be arranged on vehicle front bumper, car door and rear bumper.
In order to ensure transmission stability and the speed of data, as a preferably embodiment, collision perception unit, speed of a motor vehicle acquiring unit, processing unit and blast start unit are communicated to connect by vehicle bus.The bus utilizing present vehicle to use in a large number carries out communications, can ensure the speed of Signal transmissions on the one hand.Also there is very high reliability simultaneously.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
