The utility model discloses an automobile intelligent safety overtaking device, which comprises an emitting device (1) (7), a signal processor (2) (8), a sensor (8) (9), a sound and light alarm device (4) (10), a graphic device (5) (11), a black box (6) (12), an anti-interference casing, and an accident test printing device (13). Modulated infrared wave or ultrasonic which is resistent to external interference and can exactly transfer overtaking signals all day is used as automobile overtaking signals to lower the accident rate of overtaking on roads.
Description
The utility model belongs to automotive electronic technology.
The present signal of overtaking other vehicles is used (for example meeting signal, prompting pedestrian signal) with other signal, disperseed attention during the automobile driver operation again, simultaneously under arrow path, bend, mountain highway and various rough weather, owing to the reasons such as signal is imprecise of overtaking other vehicles, the accident that causes highway to be overtaken other vehicles.And in case the accident of overtaking other vehicles takes place, car pipe department can only measure front-and-rear vehicle distance and come the judgement accident according to the oral account of chaufeur with tape measure, is difficult to obtain all satisfied result of both sides' chaufeur like this.In view of the above, seeking the signal system of overtaking other vehicles that the front and back vehicle in a kind of the travelling takes concerted action is to reduce the overtake other vehicles effective ways of accident rate of highway.For this reason, make the utility model.
The utility model be at in-depth study under the prerequisite of the various rules that have an accident during automobile overtaking, utilize infrared modulation ripple or super sonic not to be subject to various external interference, and the principle of can all-weather accurately transmitting signal is with infrared modulation ripple or the super sonic signal of overtaking other vehicles as automobile.The signal of overtaking other vehicles of the automotive use of the utility model and present " People's Republic of China's regulation of road traffic control " the 50 defined: be sound of horn daytime, and be that the method for long-and-short distant light, conversion light is compared night, and obvious superiority is arranged:
1, the signal of overtaking other vehicles is not subjected to external environmental interference (as greasy weather, rainy day etc.).
2, the clear and definite design symbol of overtaking other vehicles is arranged, in driving, be difficult for chaufeur is misunderstood.
3, store the operation signal of various navigating mates by special-purpose black box, for car pipe department provides failure-free, quantitative analysis content and data when the analysis accident.
Automobile intelligent safety overtaking device is by feedway (1) (7), signal processor (2) (8), receiving sensor (3) (9), acoustic-optic alarm (4) (10), graphic display unit (5) (11), black box (6) (12), the disturbance rejection casing, the accident of car pipe department (c) detects type printer (13) and forms (Fig. 1).Front truck dress (7) (8) (9) (10) (11) (12), back car dress (1) (2) (3) (4) (5) (6), car pipe department (c) has (13).
Being the back car with (A) below, is front truck (B), (c) in conjunction with the accompanying drawings the present invention is specified for car pipe department:
