Situation below in conjunction with several actual Frequent Accidents of driving illustrates the importance that prevents the prior-warning device that automobile is knocked into the back that employing is above-mentioned.
Automobile one starts all relevant with throttle, advances and accelerates and will refuel, and ramp to stop will subtract oil.Chaufeur is when running into the burst emergency situation under normal circumstances, and the first reaction is exactly that anxious accelerator releasing touches on the brake, to realize the parking hedging.And the normal person does another action abandoning an action, needs the 0.5-1 reaction time of second, to the automobile of running at high speed, calculates its 13.9-27.8 rice that advanced by 100 yardages, and 150 yards are calculated as 20.8-41.6 rice, and this is exactly the distance of saving somebody's life in danger and disaster constantly.This automobile prior-warning device that prevents from being knocked into the back gives warning in advance exactly, helps exactly you to win this help distance.
Current automobile is under normal motoring condition, only when touching on the brake, follow-uply know just that with car front truck will slow down or stop, and stoplight stop lamp is fixing red light, the stroboscopic yellow light that can not show a candle to the car emergency hazard way light is obvious, more easily causes follow-up attention with the car chaufeur.Experimental results show that, if can before front truck touches on the brake, know its deceleration or parking second by 0.5-1, thereby cause follow-up attention with the car chaufeur, and the hedging measure of taking to brake, just rear-end collision can be reduced by 80%, even the serious accident that causes car crash that the chain of rings can be knocked into the back reduces 90--95%.
This prior-warning device sends early warning when sharply changing exactly (namely sharply refuel or subtract rapidly oil) at gas, i.e. the follow-up car chaufeur of following point out in the emergent hazard way light flicker of this car, and this car is dangerous.
In addition, because chaufeur high-pressure or fatigue in driving procedure, having is exactly to desert to wait in particular cases again, and the prominent emergency situation of meeting is floored the hedging that brakes to phenomenon of taking throttle as brake one pin and miss.This situation happens occasionally in rear-end collision, and often all is the pernicious rear-end collision of car crash.Just greatly aggravated the infringement to this car because of this misoperation, even cause car crash.And the rear-end collision accident that car knocks into the back after easily causing.It is exactly when the Das Gaspedal quilt is afterburning suddenly that this prior-warning device has been arranged, and not only steps on to go down, and sends early warning simultaneously, i.e. the follow-up car chaufeur of following is pointed out in the emergent hazard way light flicker of this car, and this car is dangerous.Thereby avoid knocking into the back or the generation of rear-end collision accident.
For vehicle drive beginner or Getting Started, the defect of when stopping starting, the most easily violating, the bad strength of starting control of stopping, easily violent step on the accelerator had so both easily caused the generation of rear-end collision, and had strengthened exhaust emissions and not environmental protection.Therefore, use the above-mentioned prior-warning device that prevents that automobile from being knocked into the back to avoid because of knocking into the back of causing of faulty drive and reduce the generation of pernicious traffic story.
