Description
Technical field
The present invention relates to safety control device for automobile, particularly a kind of vehicle explosion-proof tire controller.
Background technology
Direction when suddenly puncture car tires easily get out of control deviation caused no casualties and property damage accidents, for which the industry control technology for automotive anti-puncture depth study, there are mainly the following car anti-puncture control technology: (1) ultra-flat tire technology, which is the core to minimize the height of the tire, enhanced support for tire sidewall rigidity and thus the tire after a puncture occurs, the height of the wheel without significant decline in order to provide the tire with a relatively low basic performance, the technology is to remove the original intention of automobile spare tire, not prevent a flat tire, but the technology in the event of a puncture and no advance warning after warning and rescue role, because this tire stiffness is relatively large, this will cause the car adhesion in the process of moving down, in order to improve the adhesion of travel must be achieved by increasing the width of the tire, and the tire height will decrease the tire removal more difficult, so the prospect of this technology has yet to be demonstrated; (2) direction of self-locking technology, the core idea is the use of tire pressure sensors to detect vehicle tire pressure information when detects a tire puncture occurred after locking the steering wheel in one direction, then the driver can freely manipulate steering wheel, steering wheel from lock to reduce the offset direction of the tire after a puncture, but the technology is mainly stays in appearance, but also in the experimental stage, so far not in use, and in the event of a puncture after no advance warning early warning and rescue role; (3) coaxial tire pressure interoperability technology, the core idea is to make car tires left and right wheels coaxial chamber interlinked, so that when the coaxial side of the tire after a puncture occurs, the other side Tire air will quickly spread to puncture tires, so that cars will not be because of the side rear tire rolling resistance tires and the direction of the offset is too large, thereby reducing the likelihood of accidents caused by tire; also the company made a similar Another method technologies, i.e. the detection of the tire to the side of a puncture, the other side of the tire quickly detonated, the mechanism is very similar to the technology, the reliability of this method still further verification; (4) flat tire monitoring and safety control system, the core of this technology is the use of high-precision smart car tire pressure sensor detects the information and if it detects a tire puncture occurs, the signal is immediately transmitted to the flat central processing unit, the central processing unit controls the automatic brake mechanism for braking deceleration and braking, but the car during braking lateral adhesion performance will deteriorate and it is the car's directional stability is not good, it is not excessive braking deceleration.
Can know current runflat control technology or cost is too high by above analysis, or be exactly that poor reliability or technology are not mature enough that what on market, apply also is not too many.
