Abstract
The utility model relates to a rear-ending preventing device for an automobile by active warning. The rear-ending preventing device comprises a probing sensing device, a main processor and an audible and visual alarming device electrically connected sequentially. The probing sensing device outputs a detection signal to the main processor. The main processor receives the output signal from the probing sensing device to judge whether the output signal exceeds a predetermined threshold value or not so as to decide whether an alarming signal is output to the audible and visual alarming device or not. The audible and visual alarming device receives the alarming signal from the main processor and sends an audible and visual alarming signal synchronously. The probing sensing device comprises a displacement sensor, a pressure sensor or an acceleration sensor. Compared with the prior art, the rear-ending preventing device provided by the utility model exactly judges whether emergency brake occurs for the automobile or not by collecting acceleration data or displacement data of a brake pedal or pressure data of a braking medium when the automobile brakes by the probing sensing device, and sends the audible and visual alarming signal immediately to remind an automobile behind to pay attention so as to reduce rear-ending accidents.
Description
Technical field
The utility model relates to the automotive safety technical field, especially a kind of active alarm safety apparatus that prevents automobile generation rear-end collision.
Background technology
Along with automobile enters 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, because after the front truck emergency brake mostly, rear car fails in time to understand front truck to be emergency brake or gently to touch on the brake, thereby causes braking strength inadequate, 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 to install at automobile initiatively to detect radar, car automatic retarding 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 affected 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.
The utility model content
The purpose of this utility model provides that a kind of cost is low, the automobile of easy realization is initiatively warned rear-end device, can make the automobile straight sending and receiving go out the emergency brake signal by this device, car notes taking emergency brake or Emergency avoidance measure after reminding, to reduce the generation of rear-end collision.
The purpose of this utility model is achieved by the following technical solution:
The automobile rear-end device of initiatively warning comprises detection sensing device, primary processor and sound and light alarm device that order successively is electrically connected, and described detection sensing device is to the primary processor output detection signal; Whether described primary processor receives the output signal from described detection sensing device, judges whether to exceed predefined threshold value, to determine to sound and light alarm device outputting alarm signal; Described sound and light alarm device is sounded or the light warning signal after the warning signal of reception from described primary processor, perhaps sends simultaneously the sound flash alarm system signal.
As optimal technical scheme of the present utility model, described detection sensing device comprises displacement pickup, and described displacement pickup links to each other with brake pedal and can be according to the brake pedal displacement that detects to the primary processor output detection signal.
As optimal technical scheme of the present utility model, described detection sensing device is acceleration pick-up, and the pickup value that described acceleration pick-up basis detects is to the primary processor output detection signal.
As optimal technical scheme of the present utility model, described detection sensing device is pressure sensor, and described pressure sensor links to each other with the automobile brake medium pipeline, and according to the automobile brake medium pipeline force value that detects to the primary processor output detection signal.
As optimal technical scheme of the present utility model, described sound and light alarm device comprises the loud speaker that sends the emergency brake voice prompt and sends the stoplight stop lamp of emergency brake prompting.
As optimal technical scheme of the present utility model, described sound and light alarm device comprises one group of bar shaped or cylindricality indicator lamp, and described 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 utility model, described sound and light alarm device comprises that at least one is separately set in the emergent braking lamp of automobile tail.
With respect to prior art, an advantage the utlity model has to judge: 1, lower, the easy realization of cost; The utility model is by displacement pickup, pressure sensor or acceleration pick-up, can be accurately promptly to automobile emergency brake judge 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 allow so rear car within the very first time, learn the emergency brake action of front truck, take immediately emergency brake or Emergency avoidance measure, help to prevent from knocking into the back, increase traffic safety.
2, comprehensive benefit is obvious; The utility model only needs to increase a little part at existing automobile, and the cost increase seldom prevents the safe effect that knocks into the back but greatly increased, more convenient to use and popularization.
