Compared with the prior art, the active alarming and rear-end collision preventing device of the car has the advantages that the detecting and sensing device collects acceleration data when the car brakes or the displacement data of a brake pedal or the pressure data of a brake medium so as to accurately judge whether emergency brake of the car happens, and the acousto-optical alarm signal is sent at the first time to remind a driver of a rear car to pay more attention so that rear-end collision accidents are reduced.
Description
Technical field
The present invention relates to the automotive safety technical field, especially a kind of safety device of initiatively warning that prevents automobile generation rear-end collision.
Background technology
Along with automobile gets into daily life in a large number, ride safety of automobile more and more receives publicity and payes attention to.With regard to common rear-end collision accident; Be because after the front truck emergency brake mostly; Back car fails in time to understand front truck to be emergency brake or gently to touch on the brake, thereby causes braking strength not enough, fails to cause the rear-end impact accident at finite time and the interior timely parking of distance.In order effectively to avoid and reduce the generation of rear-end collision accident, prior art generally is on automobile, to install initiatively to detect radar, car automatic deceleration after the distance between two cars is less than safety distance the time.But this kind method is initiatively detecting, feeling of passivity answers, and influenced by road speed and environment etc., and the anti-effect that knocks into the back is barely satisfactory.In addition, existing active arrangement for detecting cost is higher, and implementation method is rather complicated, can only be installed on the automobile of higher gears, popularizes comparatively difficult.
Summary of the invention
The anti-device that knocks into the back that the purpose of this invention is to provide that a kind of cost is low, the automobile of easy realization is initiatively warned; Can make automobile directly send the emergency brake signal through this device; Remind the back car to note taking emergency brake or promptly dodge measure, to reduce the generation of rear-end collision.
The objective of the invention is through adopting following technical scheme to realize:
Automobile is initiatively warned and is prevented knocking into the back device, comprises detection sensing device, primary processor and the sound and light alarm device of order electrical connection successively, and said detection sensing device is to the primary processor output detection signal; Whether said primary processor receives the output signal from said detection sensing device, judges whether to exceed pre-set threshold, to determine to sound and light alarm device outputting alarm signal; Said sound and light alarm device is sounded or the light warning signal after the warning signal of reception from said primary processor, perhaps sends the acousto-optic warning signal simultaneously.
As optimal technical scheme of the present invention, said detection sensing device comprises displacement pickup, and said displacement pickup links to each other with brake pedal and can be according to detected brake pedal displacement to the primary processor output detection signal.
As optimal technical scheme of the present invention, said detection sensing device is an acceleration pick-up, said acceleration pick-up according to detected pickup value to the primary processor output detection signal.
As optimal technical scheme of the present invention, said detection sensing device is a pressure sensor, and said pressure sensor and braking automobile braking medium pipeline links to each other, and according to detected automobile brake medium pipeline force value to the primary processor output detection signal.
As optimal technical scheme of the present invention, said sound and light alarm device comprises loud speaker that sends the emergency brake voice prompt and the stoplight stop lamp that sends the emergency brake prompting.
As optimal technical scheme of the present invention, said sound and light alarm device comprises one group of bar shaped or cylindricality indicator lamp, and said indicator lamp is according to the braking strength corresponding increase of size or reduce the quantity that shows bar shaped or cylindricality light piece.
As optimal technical scheme of the present invention, said sound and light alarm device comprises that at least one is separately set in the emergency brake lamp of automobile tail.
With respect to prior art, the present invention has with an advantage that judges: 1, lower, the easy realization of cost; The present invention is through displacement pickup, pressure sensor or acceleration pick-up; Can accurately promptly the automobile urgent brake car be judged and point out; According to the brake pedal stroke or trample the dynamics of brake, the reduction value of pickup in the unit time, emergency brake or general brake are judged; Whether determine to sound and light alarm device outputting alarm signal according to judged result.Can let the back car in the very first time, learn the emergency brake action of front truck like this, take emergency brake immediately or promptly dodge measure, help to prevent to knock into the back, increase traffic safety.
2, comprehensive benefit is obvious; The present invention only needs on existing automobile, to increase a little part, and the cost increase seldom prevents the safe effect that knocks into the back but increased greatly, and is more convenient to use and promote.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, survey sensing device, 2, primary processor, 3, sound and light alarm device.
