The invention has the beneficial effects as follows: by ramp rate sensor and acceleration pick-up, the slope trend to vehicle makes anticipation, the safety air bag triggering corresponding side when vehicle run-off the straight in time starts, the safety of protection navigating mate and passenger.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art 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 the control block diagram of a kind of side-turning proof safety system of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Accident research shows, safety air bag can reduce the chance of injury of navigating mate greatly, but during vehicle rollover, only forward side air bag is difficult to reach actv. protection, and moment occurs rollover accident, when front airbag-releasing, can cause unnecessary injury.
The present invention by ramp rate sensor and acceleration pick-up the slope trend to vehicle make anticipation, the safety air bag triggering corresponding side when vehicle run-off the straight in time starts, protection navigating mate and the safety of passenger.
As shown in Figure 1, a kind of side-turning proof safety system, comprising: ramp rate sensor 11, is arranged on the vehicle frame center pillar of both sides, detects vehicle angle of inclination, exports angle signal; Acceleration pick-up 12, is connected to gauge panel speed display instrument, detects vehicle acceleration, exports acceleration signal; A/D converter 13, is connected to described ramp rate sensor and acceleration pick-up, described sensor output analog signals is converted to digital signal; Controller 22, is connected to the mouth of described A/D converter, by the output signal of described sensor compared with internal reference, exports control signal; First safety air bag 31, is arranged on ceiling above left-hand door, and deployed condition covers left-hand door glass; Second safety air bag 32, is arranged on ceiling above right car door, and deployed condition covers right automobile door glass; The control signal that the controlled device of opening and closing of described first safety air bag 31, second safety air bag 32 exports controls.
Preferably, the expanding body integration of the first safety air bag, the second safety air bag and the 3rd safety air bag is three kinds: launch pattern, 80% expansion pattern and 50% expansion pattern completely.
