Description
Technical field
The present invention relates to safety control device for automobile, particularly a kind of automobile tire burst prevention controller.
Background technology
The easy sideslip out of control of direction caused casualties and the property damage accident when motor tire was blown out suddenly, industry is done deep research to the automobile tire burst prevention control technology for this reason, mainly contain at present following several automobile tire burst prevention control technology: (1) super flat tire technology, the core of this technology is the height of reduce motor tire, strengthen the support rigidity on motor tire sidewall, thereby after the wheel Somatic Embryogenesis is blown out, the height of wheel is not significantly descended, in order to the basic rideability of relative low speed is provided for tire, the original intention of this technology is to remove stepney, be not that preventing car is blown out, and this technology after blowing out, also do not report to the police in advance early warning and relief effect, because the ratio of rigidity of this kind tire is larger, will cause like this automobile adhesive ability in the process of moving to descend, want to improve the adhesive ability that travels and just must realize by the width that increases tire, and the tire height descended and can make relatively difficulty of tire dismantling, so the application prospect of this technology is still waiting demonstration; (2) direction is from lock technology, the core concept of this technology is to adopt tyre pressure sensor to detect the tire pressure of motor tire, take turns and just bearing circle is carried out unidirectional self-lock after Somatic Embryogenesis is blown out when detecting certain, this moment, chaufeur can free steer direction dish, can alleviate tyre explosion direction skew afterwards after the bearing circle self-locking, but this technology mainly rests on the presentation, also be in test session, up to the present also there is not place in operation, and after blowing out, also do not report to the police in advance early warning and relief effect; (3) coaxial wheels air pressure interworking technology, the core concept of this technology is that the air chamber of the left and right wheels of the coaxial tire of automobile is communicated, like this after the wheel Somatic Embryogenesis of a coaxial side is blown out, the gas of opposite side tire can pass to the tire of blowing out by fast speed, automobile just can not be because of a side wheel the tire excessive and direction of the rear rolling resistance skew of blowing out like this, thereby reduces the possibility that causes the accident of blowing out; Also have company to propose the another kind of method of similar this technology, namely detecting after a side wheel Somatic Embryogenesis blows out, ignite fast the tire of opposite side, quite similar with this technology mechanism, the reliability of this method is also in further checking; (4) blow out the monitoring and safety control system, the core of this technology is to utilize high-precision Intelligence sensor to detect the pressure information of motor tire, if detecting certain takes turns Somatic Embryogenesis and blows out, then at once signal of tyre burst is transferred to central processing unit, central processing unit can be controlled automatic brake mechanism and carry out braking deceleration and brake, but the side direction adhesion value of automobile is with variation in braking procedure, and namely road holding is bad, so excessive braking deceleration.
