Abstract
The utility model discloses a car gets into automatic opening device of passing lamp before tunnel, it is including installing the laser radar in car the place ahead air -inlet grille centre, install the treater at the inboard nook of steering wheel below baffle, and by the passing lamp of its switching of treater control, laser radar is used for acquireing car the place ahead road information to give the treater with car the place ahead road message routing, the treater is used for carrying out the analysis to car the place ahead road information that laser radar gathered and makes analysis result to relatively make evaluation result with the actual range between tunnel and the car and default distance, control the passing lamp according to analysis result and evaluation result and open. Adopt above -mentioned device, when analysis result for there being the tunnel, and the actual range is when being less than default distance, treater output pin producing signals makes the passing lamp open, the driver just can be very clear before getting into the tunnel this moment sees and in time makes corresponding action by the road condition in the tunnel, avoids the emergence of traffic accident.
Description
Technical field
The utility model relates to automotive lighting field, and particularly a kind of automobile enters passing light automatic open device before tunnel.
Background technology
When automobile enters tunnel, chaufeur can pass through the environment of a relative darkness, human eye needs the adaptation time of about 3 ~ 10 seconds, during this period of time, eyes are in fringe substantially, though have illuminating street lamp in some tunnels, but still can not compared with daylight, as car bulb is not opened, chaufeur can not find in time and process contingent emergency situations, and the accident of car crash just likely can occur.If car light is opened after entering tunnel, driver's eyes during this period of time will be in fringe, because vehicle travels speed on road, may cause serious traffic accident equally.
Utility model content
The purpose of this utility model is to provide a kind of being arranged on that automobile enters passing light automatic open device before tunnel, and this installation cost is low, be applicable to large-scale promotion, without the need to M/C and reliability is high.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme to be achieved.
A kind of automobile enters passing light automatic open device before tunnel, comprises and is arranged on the Centromedian laser radar of vehicle front air-inlet grille; Be arranged on the treater in shelter inside baffle plate below bearing circle; And controlling its passing light opened by treater, vehicle front road information for obtaining vehicle front road information, and is sent to treater by described laser radar; Described treater is used for carrying out analysis to laser radar collection vehicle front road information and makes analysis result, and the actual distance between tunnel with automobile is compared with predeterminable range result of making an appraisal, and control passing light unlatching according to analysis result and evaluation result.
As preferably, described predeterminable range is 20 meters.
As preferably, described laser radar is the SE-J1200A model laser radar of Tian Yan laser Science and Technology Ltd..
As preferably, described treater is Freescale S12 series microprocessor.
As preferably, described processor model is MC9S12XS128.
The beneficial effects of the utility model are: adopt said apparatus, laser radar is utilized to obtain the road conditions of vehicle front, collection road information is transferred to treater, treater is through pretreatment, judge whether front has tunnel, and the distance between real-time detection vehicle and the portal detected, whether described analysis result is for existing tunnel, described evaluation result is whether described actual distance is less than predeterminable range 20 meters, when described analysis result is for existing tunnel, and described actual distance is when being less than predeterminable range, treater output pin produces signal, passing light is opened, if passing light is opened before entering tunnel, so chaufeur just very clearly can see the road conditions in tunnel before entering tunnel, make corresponding action in time, by the generation avoided traffic accident.
Accompanying drawing explanation
Fig. 1 is principle of work block diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of automobile described in the utility model enters passing light automatic open device before tunnel, comprises laser radar, treater, passing light.
Described laser radar is arranged on vehicle front air-inlet grille centre, for obtaining vehicle front road information, and vehicle front road information is sent to treater; Described laser radar is the SE-J1200A model laser radar that Tian Yan laser Science and Technology Ltd. produces.
Described treater to be arranged on below bearing circle shelter inside baffle plate, attractive in appearance and facilitate wiring; Described treater I/O interface is electrically connected with laser radar output signal line; Described treater is Freescale S12 series microprocessor, and concrete model is MC9S12XS128.Described treater is used for analyzing laser radar Information Monitoring and making analysis result, and makes an appraisal and result of making an appraisal to the actual distance between tunnel and automobile.For there is tunnel and there is not two kinds, tunnel situation in described analysis result, treater, by judging whether front has diameter to be greater than the depression of 7.5 meters, judges whether front has tunnel.Described evaluation result is that described actual distance is less than predeterminable range 20 meters, and described actual distance is not less than predeterminable range 20 meters.When analysis result is for existing tunnel, and when actual distance is less than predeterminable range 20 meters, system is thought unsafe, and treater controls to open passing light.
When triggering automobile ignition switch, this system starts, and by the road information of laser radar Real-time Collection vehicle front, treater removes useless point and noise spot to Information Monitoring, then analyzing and processing is carried out to road information, judge whether road ahead exists tunnel, and by predeterminable range compared with the actual distance in the road information of detection between Tunnel ahead with vehicle, judge that the passing light of vehicle is the need of unlatching, detailed process is, when there is tunnel, and actual distance is when being less than predeterminable range 20 meters, system is thought unsafe, treater controls to open passing light, to ensure that chaufeur can see situation in Tunnel ahead clearly accurately, thus ensure the driving safety of vehicle.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
