Description
Technical field
The present invention relates to automobile assistant driving technical fields, and in particular to a kind of vehicle blind zone monitoring and warning system and side
Method.
Background technique
In recent years Chinese automobile and Traffic conflicts are grown rapidly, but various traffic accidents also occur again and again, are caused wide
General concern, or even become serious social concern.According to another authoritative investigation statistics, since the vehicle in driving process has observation
Blind area and crash and accounted for significant proportion.In front of the left and right sides of automobile, left and right sides rear and tailstock left and right sides be
Viewing blind zone.For some oversize vehicles since vehicle body is big, headstock is high, wheelbase is long, existing blind area can be more, at car door and Chinese herbaceous peony
The region of side is all likely to become blind area.
It is at present to change the shape of existing rearview mirror for the most common solution of kart, or in common backsight
Increase a small rearview mirror on the basis of mirror.But if gluing one small wide-angle circle mirror on eyeglass ontology, sighting distance error can be very big,
In addition there are also effective areas, and small, anamorphose is distorted the disadvantages of big.In addition, multiple auxiliary observation mirrors or camera are installed, although
The observation to vehicle tail, left and right rear side may be implemented, but may also lead to driver and need while paying attention to multiple auxiliary views
Mirror is easily dispersed attention in this way, is unfavorable for safe driving.Although having some solution visuals field now for kart
The scheme of blind area, but for truck always without preferable total solution.Foreign countries are mainly by large car at present
Blind area demarcated, the pedestrian that gives a previous notice, non-motor vehicle etc. are far from blind area, active escape from danger region.The country is still within
Primary stage generally onboard installs voice prompt device additional, i.e., when vehicle prepares to turn right, sends out voice prompting, prompt
Pedestrian etc. is far from blind area.It is also disclosed some rearview mirrors for blind area monitoring in the prior art and turns to hunting gear, passes through company
Rearview mirror and automobile steering system are connect, rearview mirror is made to follow the steering of automobile and rotate, reduces automobile during the turn, due to
The viewing blind zone that turning radius is poor and is formed, so that driving safety is improved, but this solution can only be in turning, lane change
When play a role, and be unable to the various road conditions of flexible adaptation.To sum up, various types vapour is not still can be suitably used in the prior art
Vehicle and the preferable blind area monitoring and warning system of using effect.
Summary of the invention
