Description
Technical field
The utility model belongs to HUD technical field more particularly to a kind of intelligent dimming drives display device.
Background technique
HUD (head-up display system) projects all kinds of display information on the front windshield of automobile in real time.HUD can be with
Driver need not bow, important information can be seen clearly；Driver is avoided to disperse because of the movement bowed to road ahead
Attention, can also reduce driver observe distant road situation with closely check that navigation, information of vehicles sight frequently turn
Change the visual fatigue of initiation.Currently, the first is conventional reflector formula HUD there are mainly three types of HUD on the market, by by terminal
The transparent reflection film of display content projection windshield after mirror image processing, thus in the head up display of eyes imaging.It is this kind of
HUD mainly includes that a HUD host and one piece of semi-transparent semi-reflecting projection film directly glue projection film after installing HUD host
It is attached to the suitable position of shield glass.This kind of HUD purchasing price is very cheap, but the display effect on daytime is non-
It is often poor, it does not see almost, only night can just show colorful color, and it is easy to appear ghost images when in use.
Second is transparent screen HUD, and product carries one piece of transparent OLED display screen, this is that a solidified using transparent screen shows content
Head up display.Transparent screen HUD is directly installed on above instrument board and uses, and display effect is got well than reflection type mirror HUD, still
Display position is relatively low, without depth feelings, on this semi-transparent semi-reflecting optical thin film that can also project windshield stickup, at this time
It needs to show OLED into content mirrors processing.The third is the reflective HUD of projection, is the new line based on DLP projection or LCD reflection
Display, the usually included transparent concave mirror of a fritter, amplifies small image, and image appears to have certain depth feelings,
But unlike described in publicity, " seeming to project on road surface ".Project reflective HUD there is also Railway Project be, visually
Angle very little, the slightly inclined inclined body of driver are possible to can't see content；In addition, some are apprehensive for imaging on four angles, have
When give the feeling of dizziness, transparent concave mirror is not suitable for being made too big.These three types of generally existing two problems of display, one
The aspect display that comes back will receive front windshield mirror surface bring reflections affect, and on the other hand, when driving quickly flashes road surface letter
Breath and outside are perforated through the ambient light come, can all cause to interfere strongly to display effect.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of intelligent dimming driving display device, it can effectively reduce front
The reflection of wind glass-mirror reduces and quickly flashes information of road surface and the external ambient light for being perforated through and when driving, promotes display
Effect.
A kind of intelligent dimming driving display device, including light modulation film, automatic control module, projector, radar, sensor；
2.5 degree of position is the area Shi Min above horizontal line where face pilot's line of vision on front windshield, on front windshield
Where face copilot sight above horizontal line 2.5 degree position for periphery field of vision, the area Shi Min and periphery field of vision about
The longitudinal centre line of front windshield is symmetrical；Light modulation film is affixed on the area Shi Min and periphery field of vision, and radar, sensor are installed on vehicle body
Outside, projector are installed on console, light modulation film, projector, radar, sensor and automatic control module electrical connection.

Glue-line is pasted on front windshield.
As a preference, projector is installed on above console by projector's mounting bracket, and the left side of projector
The right side 40cm of range direction disk center axis, the front side of projector is apart from front windshield 30cm.
As a preference, projector is the laser-projector of miniature DLP chip drives.
As a preference, radar is installed on the front side of vehicle body, the left and right sides, sensor be installed on vehicle body front and back side,
The left and right sides.
As a preference, sensor includes visual sensor.
A kind of intelligent dimming driving display methods, using a kind of above-mentioned intelligent dimming pilot instrument, radar and sensor inspection
Measuring car body surrounding enviroment information, and will test information and pass to automatic control module；Automatic control module judge detection information without
Abnormal, light modulation film remains powered on state, and pellucidity is presented in light modulation film；Automatic control module judges that detection information is in abnormal shape
State, automatic control module cut off the power supply of light modulation film, and spray pattern is presented in light modulation film, while automatic control module controls projector
Information warning is projected on light modulation film.
As a preference, automatic control module judges that detection information is in abnormality, red color lump is thrown by projector
It penetrates on the light modulation film of all field of vision outside, realizes color warning；It is simultaneously that the information warning Projection Display of concrete type is quick in view
On the light modulation film in area.
As a preference, automatic control module judges that detection information is in abnormality, light modulation film presentation 0.1 second transparent
With the flashing state of opaque alternating conversion in 0.3 second.
As a preference, this method is used for High-Speed Automatic driving, automatic control module judges that detection information is in
When abnormality, by way of information alert, driver is reminded to carry out driving adapter tube；It carries out driving adapter tube in driver
Afterwards, automatic control module switches to lasting energized state, and light modulation film becomes transparence.
Automatic control module is using 16 single-chip microcontrollers of Freescale as the automatic control module of core.
The advantages of the utility model：Light modulation film is pasted in the area front windshield Shang Shimin and periphery field of vision, and is passed through
The information for radar and sensor the detection vehicle periphery being mounted on the outside of vehicle body, and the information detected is passed into automatic control
Module, if judging detection information exception, cuts off the power supply of light modulation film, so that light modulation film by the judgement of automatic control module
Information warning is projected on light modulation film in spray pattern, and by projector, so that driver pays close attention to information warning,
And detection information it is not abnormal when, then do not influence to drive when keeping the pellucidity of light modulation film, therefore abnormal conditions can be not detected
The visual field of member, information warning can be clearly displayed when detecting abnormal conditions, display effect is good, and it is normal not influence vehicle again
Driving；When abnormal conditions, red color lump will be incident upon on the light modulation film of periphery field of vision, realizes color warning, simultaneously
In the case where specifically warning type information Projection Display that can cause driver alert at the same time on the light modulation film in the area Shi Min again
Driver is allowed to notice detailed information warning；When detecting abnormal conditions, automatic control module can control projector and to adjust
Display in 0.1 second and 0.3 second transparent continuous alternate persistently transition status is presented in light film, while prompting driver alert again
Avoid blocking the visual field of driver；The right side 40cm of the left side range direction disk center axis of projector, the front side distance of projector
Windshield 30cm, therefore not only drop shadow effect is good, and can guarantee the normal driving for not interfering driver.
