Advantage of the present utility model:
The utility model is not changing the original device of vehicle, does not increase under the principle of driver's mental burden, has solved the weak point of original device preferably, has possessed fog precipitation snow, road barricade, the four kinds of functions of normally overtaking other vehicles, overtake other vehicles by force; Adopt two kinds of light, the voice modes of prompting simultaneously, early warning in advance in 200 meters active distances, and easy to use, quick and precisely, make the driver have the sufficient time take to dodge, slow down, measure such as parking, avoid or reduce traffic accident taking place.
1, fog precipitation snow function: to be that driving is big avoid fog precipitation snow weather, and when bad climate occurring, all driving vehicles are all opened this signal, make the driver know that front and back have or not vehicle ', thereby strengthen observing, and deceleration is gone slowly.Avoided can't see the wigwag of front vehicles because of the road poor visibility, dodge too late a period of time again when finding, cause several and even tens major traffic accidents that car knocks into the back mutually.
2, road barricade function: road barricade mainly contains roadupkeep, obstacle, car accident etc., when driving vehicle finds that obstacle appears in road ahead, press the roadblock button, back car receives that front truck roadblock signal feeds back front truck at once, or back car give a signal rearward again, make the interlock of driving vehicle roadblock signal, in time take measures.
3, the function of normally overtaking other vehicles: when driving vehicle need be overtaken other vehicles, press the button of overtaking other vehicles, front truck receives that the car signal of overtaking other vehicles in back feeds back the back car at once, and expression back car can be overtaken other vehicles.And front truck is initiatively dodged or is slowed down, and creates safety condition easily when overtaking other vehicles for the back car, and the back car is passed through smoothly.Avoided inaccurate, reacted accident untimely or that overtake other vehicles by force and cause because of judging.
4, the function of overtaking other vehicles by force: be that national public servants, public security traffic, road remove obstacles, fire-fighting, rescue etc. be when executing the task, the special-purpose control key that its vehicle uses, the function that also possesses simultaneously the general vehicle precaution device, when needs use, start this function (the general vehicle precaution device can only receive this signal, and can not launch this signal), front truck receives that this signal immediately reacts, and initiatively take to dodge, slow down or stop, it is passed through safely, improved work efficiency.Avoided can't hear because of reasons such as vehicle good seal performance, full size vehicle noise height, and then do not dodge, do not slow down (deliberately except the factor), the passive situation that makes it be difficult to pass through.
Because far infrared has special wavelength, this device in view of emission is to adopt the pulse standard, does not have misidentification to the non-pulse wave that is provided with to not reaction of visible light yet, and therefore, its identification error is zero.
