Background technology
Automobile on road surface gets more and more, and vehicle accident is more and more frequent.During galloping, owing to the effect of inertia of material, automobile and passenger thereof store huge inertia energy.Just in case at this moment automobile generation head-on crash, these energy abrupt releases, will produce huge impulsive force, its consequence is hardly imaginable.Because during frontal crash of vehicles, speed moment reduces, and even replys resting state.Passenger inside the vehicle, during this, will bear huge forward impact power, will be it is therefore possible to injured.In prior art, in order to when collision scenario, buffer the impulsive force of the person, people have invented air bag.But, statistical data according to some national highway safety management departments, while air bag often saves 100 passenger life in collision vehicle accident, also because of the inappropriate expansion of air bag and the incorrect seating position of occupant and sitting posture, unfortunately 57 occupants are caused to lose life.
In real world, the collision of automobile is to occur moment, and again in moment knot speed, the short people of being of its time cannot perceive.When car accident occurs, particularly in the accident of vehicle front collision, air bag to play a role and necessary to complete in the moment that human body starts to turn forward, and the secondary accident hurted sb.'s feelings during airbag-releasing the most easily occurs.Will within the shortest time airbag opening, such requirement is extremely harsh, because collision does not has any tendency, nobody can know that when occur, and it opens, for air bag, the time leaving a little.For solving this technical problem, in prior art, it is all to produce huge air pressure by system ignition charge, utilizes gases at high pressure airbag-releasing.Speed during air-bag deployment is the most high in this case, and its impact dynamics is equivalent to ignite a small-sized bomb at one's side people.Although air bag quality is little, but this impact velocity is not a peanut for human body, if the very high speed that it is opened unfortunately is hit, its consequence is serious equally.Above-mentioned reason is always to have so much people to be hindered even main causes of death by air bag.
If air bag is opened proper, can be to add an air cushion between human body and body of a motor car to absorb the inertia energy of human body, play certain protective effect.If but open improper, it is likely that killer can be become.Detect in existing technology that car crass leans on is velocity sensor, problem be that velocity sensor have to send out heavily collide time, velocity sensor just has signal to export, such arrangement stays to the time of airbag-releasing extremely short, will open air bag in the shortest time, prior art have to be by the method for blast.Explosive Energy produces rapidly gases at high pressure airbag-releasing, but the highest speed can produce the biggest impact.The biggest impact energy is fatal equally.Visible, the effort of indented material is the most not fully up to expectations, and still have greatly improved space.How allowing automobile allow air bag open before colliding is purpose of the present invention place.
Summary of the invention
In order to make air bag safety can open before collision scenario, avoid air bag after collision scenario, open when human body leans forward and easily hurt sb.'s feelings, this invention takes following technical measures: range unit is installed on automobile and is used for measuring this car and front truck or other barriers of this car and distance, range unit connects computer, computer connects the igniter of gas generator, gas generator connecting safety air bag.
In order to make air bag safety can open before collision scenario, avoid air bag after collision scenario, open when human body leans forward and easily hurt sb.'s feelings, this invention takes following technical measures: range unit is installed on automobile and is used for measuring this car and front truck or other barriers of this car and distance, range unit connects computer, computer connects the igniter of gas generator, and gas generator connects air relief valve, air relief valve connecting safety air bag.
Benefit of the invention is that the distance of this car and front truck or this car and other direction barriers can constantly be measured by diastimeter by installing diastimeter on automobile.After the data recorded pass to computer, computer just can calculate Ben Che and front truck or this car and the relative velocity of other barriers and instant distance.Computer uses artificial intelligence to judge whether the safe coefficient between two cars or this car and other barriers reaches dangerous grade, decides whether to open according to the assessment of this intelligence or the time of airbag opening and mode.Thus can make the decision whether air bag is opened before collision scenario, provide the time of abundance to opening of air bag.The invention difference from existing technology is that it can be before collision scenario, and passengers inside the car's health is at the front opening air bag that leans forward.Air bag is made to have time enough and to select gentle blast or can open in the least inoffensive mode of dynamics of decompression after blast.Overcome opening of air bag in prior art to open with very fast, the technological deficiency easily hurted sb.'s feelings, the shortcoming hurted sb.'s feelings is reduced or eliminated greatly in air bag opening procedure, preferably protects the safety of occupant after collision occurs.
Detailed description of the invention
Using the generation of acceleration transducer detection car crass in prior art, this measure causes air bag just can only open after collision scenario, and this is the root of problem existing for air bag.Air bag to open competence exertion safeguard protection effect to human body within the extremely short time before collision scenario leans forward.This is an extremely exacting terms, and therefore, the mode that blast can only be used in the prior art to open is opened.But this unfolding mode itself is again a kind of mode being in extreme danger.The present invention, in order to overcome above-mentioned technological deficiency, have employed the generation of intelligent decision car crass, prevents in advance, the way opened in advance.Open in advance, it is simply that front opening air bag or start the program of opening and open will collided.The present invention is in order to reach the effect above, have employed the technological means that artificial intelligence predicts that when the time of collision generation substitutes detection collision scenario under prior art, speed morphs, by can be so that opening of air bag strives for the more time, make air bag can use multiple secured fashion, at collision scenario front opening.
The present invention installs diastimeter on automobile, constantly finds range the barrier of the place side that vehicle front or the present invention are installed with diastimeter.Diastimeter connects computer, and computer processes the data collected, and calculates Ben Che and front truck or the relative velocity of barrier and distance.When both relative velocity and distance reach dangerous degree, computer starting artificial intelligence calculates the time point that two cars or automobile will collide, the then airbag opening in a secured manner of the appropriate time before this time point with barrier.
The definition of above-mentioned degree of danger depends primarily on the response time of system, and wherein the safety of air bag opens the time used is crucial.Be contained in the front of automobile by the present invention as a example by.For guaranteeing safety, preferably before colliding, air bag can be opened safely.That is relative distance Y between automobile and the barrier in front, divided by the relative velocity X between current automobile and front truck, the time T of gained, it is necessary to open the time used more than the response time Z(air bag safety of system), this is to ensure that the safe most important condition.That is when Z is for time fixing, and X is the biggest, and the risk distance (risk distance under this speed) between automobile and barrier is the longest.Otherwise it is the most anti-.It it is exactly dangerous degree when T is equal to or less than Z.This relation illustrates there is different warning distances (or claiming risk distance) under different relative velocities.This rule is just applicable to automobile varying environment in use, and it can effectively avoid misoperation.Such as when berth, parking lot, automobile is the least with relative speed X of periphery object, has been fixing due to Z, so allowing automobile the least with the relative distance of barrier (risk distance under this speed).Can ensure that park be time, the least relative distance Y, air bag also will not be opened, efficiently avoid misoperation.On the other hand, when automobile travels with normal speed, the risk distance that system allows just is greatly increased.These characteristics are consistent with surface conditions.
