Technical field
The present invention relates to automobile safety protective technical field, more particularly, the control method of security diagnostics module when relating to a kind of automobile rear-collision.
Background technology
Along with the sharply increase of automobile pollution, the casualties that automobile collision accident causes has become the serious problem of society today widely paid close attention in the world, and automotive safety also becomes the important topic of car industry.For reducing the injured risk of passenger and the outer personnel of Che in collision accident, each auto vendor constantly researches and develops collision safety technology, increases the quantity of the security configurations such as air bag simultaneously.But, because crash event is very short, require that each security configuration must be in place within a few tens of milliseconds, therefore a lot of security configuration is all promote with gunpowder point is quick-fried, opportunity as quick-fried in fruit dot is improper, client not only can be made to complain the mistake effect of security configuration, and the huge explosive force of gunpowder can bring unexpected injury to occupant.Therefore, usually need security configuration not work in low speed collision situation, and correctly in place in high velocity impact situation.
In the research and development link of automobile safety protective technology, the work of various security configuration needs to carry out Accurate Calibration by series of experiments opportunity, acts on risk by mistake, play the object of protection passenger to reach reduction.
As shown in Figure 1, in prior art, a kind of automotive safety configuration-system comprises: front crash sensor 301,302, side collision sensor 303,304, security diagnostics module 40, car body control module 50, door solution lock unit 511, double jump lamp 512, remote assisting system 410, front impact airbag 411, side collision air bag 412, safety belt pretensioner 413 and battery relay 414(as the high pressure breaker device of cutting off the electricity supply, get an electric shock to prevent occupant).Wherein, front crash sensor 301,302 for measuring the pickup at vehicle traveling direction when collision occurs, and is supplied to security diagnostics module 40; Side collision sensor 303,304, for measuring pickup when collision occurs on the direction vertical with vehicle traveling direction, is also supplied to security diagnostics module 40.Pickup when security diagnostics module 40 occurs according to collision on vehicle traveling direction and perpendicular direction sends instruction to car body control module 50, and controls corresponding security configuration module and carry out action.Car body control module 50 control gate solution lock unit 511 unlocking doors, light two flashing light 512.Security diagnostics module 40 is reported to the police by remote assisting system 410 simultaneously, all or part of when judging severe crash occurs in security diagnostics module 40 quick-fried front impact airbags 411, side collision air bag 412, safety belt pretensioner 413 and battery relays 414.Wherein, security module judges that the standard of generation severe crash comes from measurement and calibration in an experiment, and this standard is used as parameter of measurement with velocity contrast before and after car crass usually.
Although automobile rear-collision fatal rate is lower, it easily causes whiplass, and after neck wound, the process of rehabilitation is very complicated, very long, some or even the permanent injury that can not be cured.The occupant injury that rear collision brings has caused the concern of auto vendor.
Release in prior art automotive safety protection mainly pay close attention in an experiment with front collision and side collision operating mode the work to various security configuration demarcate opportunity; and then the action of various security configuration is controlled when colliding and occurring; although these security configurations can reduce the injured risk of occupant in rear collision accident to a certain extent; but; due to these technology seldom focus on even ignore automobile rear-collision time security protection to occupant; and the more situations such as collision rift fuel leakage of paying close attention to, therefore fail to meet the automotive safety demand day by day risen.
Therefore, the control method of security diagnostics module when being necessary to design a kind of automobile rear-collision, the risk of security configuration effect by mistake when it can reduce automobile rear-collision effectively.
