Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Head up display system as shown in Figure 1, including head up display 1, instrument 12, camera 2 and rotating mechanism 10.
As shown in Figure 1, the head up display 1 includes control module 11, the display screen 7 being connect respectively with control module 11
The image reflecting surface 8 being connect with power management module 6 and with display screen 7.As shown in Fig. 2, head up display 1 is arranged in instrument
The position of 4 lower section about 50mm of dash board.Head up display 1 is managed required power supply by power management module 6, when vehicle electricity
When source is in ON gears 13, head up display 1 is opened, and is closed when vehicle power supply is in off gears.
As shown in Figure 1, the instrument 12 is connect with control module 11, control module 11 obtains letter to be shown from instrument 12
Breath（Such as：Important navigation information and warning message）And it is sent to display screen 7 and shows, and pass through image reflecting surface 8 and gear
Wind glass 9 amplifies in back reflection to driver's eyes.
As depicted in figs. 1 and 2, the camera 2 is arranged in front of driver, for acquiring driver eye positions, and
Obtain eye position information.In the present embodiment, camera 2 is mounted on sunshading board 3, is connected by LVDS lines and control module 11
It connects, can more accurately read driver eye positions.
As shown in Fig. 2, the output shaft of rotating mechanism 10 is connect with image reflecting surface 8, for adjusting the angle of image reflecting surface 8
Degree and position, such as：It moves left and right and/or is moved forward and backward and/or moving in rotation.In the present embodiment, rotating mechanism 10 is existing
There is technology, details are not described herein again.
As shown in Fig. 2, the camera 2 and rotating mechanism 10 are connect respectively with control module 11,11 basis of control module
The eye position information generates image reflecting surface rotational angle information, and image reflecting surface rotational angle information is sent to and is turned
Motivation structure 10.Rotating mechanism 10 is moved according to the image reflecting surface rotational angle information-driven described image reflecting surface 8 received；
By image adjustment to optimum field position.Such as：When control module 11 judges that image is to the left, then driven by rotating mechanism 10
Image reflecting surface 8 moves right, and image is adjusted to the right optimum position.Similarly, when control module 11 judges that image is to the right,
Then drive image reflecting surface 8 that image is adjusted to optimum position to the left to left movement by rotating mechanism 10.The control module
11 obtain display area information also according to eye position information, and control module 11 adjusts display screen 7 according to the display area information
Display area size, by image adjustment to most suitable size.I.e. when control module 11 judges according to eye position information
Go out the distance between eyes and the windshield 9 of driver it is nearer when, then it is assumed that image is too small at this time, need adjust display screen 7
Display area.Such as：The display gross area of display screen 7 is S, is 0.5S, but image is too small at this time before adjusting, and needs to increase aobvious
Show area, display area is adjusted to S automatically shows.
As shown in Fig. 2, also the eyes of driver and windshield can be measured with distance measuring sensor 5 in the present embodiment
The distance between 9, distance measuring sensor 5 is mounted on windshield 9, which connect with control module 11.Control
Module 11 adjusts the size of the display area of display screen 7 based on the distance between eyes and windshield 9.
As shown in figure 3, the system logic of the utility model.Driver's open system, system judge that " image automatically adjusts
No unlatching ".If be not turned on, system image automatic regulation function does not work.If opened, " detection of camera 2 drives system
Member's eye position ", and pass through after the data that LVDS bundle of lines detects are sent to control module 11, control module 11 first judges " to scheme
Seem no in optimum position ".If system directly carries out " whether image size properly judges ", if not, system will be schemed
After " adjusting to optimum position ", then " whether image size properly judges " carried out.If system judges image, size is suitable, is
System is directly entered " camera 2 detects driver eye positions " next time, if image size is improper, control module 11 is figure
As being carried out again after adjusting to suitable size " camera 2 detects driver eye positions " next time.
