Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Fig. 1 to Fig. 5 is please referred to, the present invention provides a kind of vehicle-mounted new line display methods, comprising the following steps:
Step S1, system initialization, modules are initialized in system.
Step S2, information collection and reception, including the acquisition of OBD data, intensity of illumination identification, rearview mirror host information biography
Defeated, external equipment information receives.Specifically, in the present embodiment, the acquisition of OBD data is to realize HUD and vapour by vehicle-mounted ODB interface
The connection of the car running computer (ECU) of vehicle, and then system can be in convenient reading vehicle ECU about speed, revolving speed, tire pressure, machine oil, vapour
It oil, tire temperature, error code etc. but is not limited to these parameters and communicates parsing module by OBD OBD data are parsed into corresponding vehicle
Information.Specifically, in the present embodiment, intensity of illumination identification process is to acquire environment real-time lighting intensity by photosensitive sensor,
It is transmitted to HUD and carries out intensity of illumination identification, carry out the adjustment of HUD backlight illumination, by environment-identification intensity of illumination to reach
Optimal display result.Specifically, in the present embodiment, the transmission of rearview mirror host information is that the rearview mirror main body passes through UART serial ports
Be connected with HUD of the invention, wherein host information transmission transmitting be the rearview mirror host send need HUD to show
Data or control command.Rearview mirror host acquisition rear of vehicle environmental information (including speed/revolving speed, navigation information etc.
Information of the inconvenience in rearview mirror LCD) it is transmitted to HUD and is shown, avoid driver from frequently checking rearview mirror bring
Inconvenient and security risk.Host is by UART serial ports or USB interface and HUD communication connection of the present invention, by the navigation picture on host
Face and booting welcome page are shown on head up display HUD.Specifically, in the present embodiment, external equipment information reception process
It is to be connect by communications such as bluetooth module or WIFI modules with external equipments such as mobile phones, HUD can by ANCS agreement
It obtains the information in mobile phone and carries out the content in mobile phone to throw screen display, the screen of mobile phone can be projected to the display screen of HUD
On, or will incoming call, information (such as wechat) be shown on the display screen of HUD, facilitate driver to check mobile phone, avoid because operation
Mobile phone and bring security risk.
Collected information is carried out being processed and converted to accord with by step S3, information processing and conversion, the microcontroller in HUD
Number, one or more of figure, text, number output information exported, these information are carried out to throw screen display；
Step S4 adjusts display effect, and the adjusting of display effect is carried out to output information.Before each depot's vehicle
Windshield is inclined-plane, the plane of HUD to front windshield be not it is parallel, additionally, due to the vehicle having front windshield also
Divide single layer, bilayer, different car owners can also carry out pad pasting to windshield, and have one layer of patch to have two layers of patch the case where, such HUD warp
It crosses reflection multilayer and refraction may cause ghost image, and one layer of reflective membrane can be pasted and be modified, simultaneously because Chinese herbaceous peony windshield is
Inclined, it is inclined to distort to lead to the content projected away, as shown in figure 5, one " H " is projected from the position HUD, by front windshield
Oblique angle and adhering film to glass reflected refraction be finally shown " A " to distort or fall " A ", so being shown
It adjusts.Specifically, the display of output information is adaptively adjusted by display enhancing algorithm and intensity variation in the present embodiment
Effect.
As shown in Fig. 2, the realization of display enhancing algorithm is the following steps are included: step for the flow chart of display enhancing algorithm
S41, HUD content are shown；Whether step S42, display feedback, feedback display content need to adjust, and such as show that content does not need to adjust
It is whole then to enter in next step, it is reversely adjusted if display content needs to adjust, completes to enter in next step after reversed adjust.Institute
Stating reversed adjust is angle and the direction for adjusting HUD display screen, makes the plane keeping parallelism of HUD display screen and front windshield
(as shown in Figure 4).Whether the display effect of step S43, display effect confirmation, confirmation display content are correct, if showing correctly
It is shown, such as shows incorrect, then return to the step S42.Specifically, user can be aobvious according to adjusting the case where HUD
The effect shown, for example " A " for being shown and distorting is seen in front of HUD projection, it at this moment can be according to the step S42's
Display feedback needs to adjust display effect to determine, then corresponding " H " by the display for customizing LCD in HUD is changed to down " A ",
The display effect projected away in this way is just offset, and then confirms display effect again, until being adjusted to relatively good angles of display.
As shown in figure 3, the process adaptive for intensity of illumination, specifically includes the following steps: step Q1, acquisition environment is real-time
Luminous intensity, system acquire the variation of ambient light intensity by photosensitive sensor；Step Q2, by ambient light intensity and backlight illumination
It is classified, varying environment luminous intensity corresponds to different backlight illuminations；Ambient light intensity is classified from 0X00-0XFF, it is different
Ambient light intensity corresponds to different backlight illuminations, and backlight illumination is accordingly divided into 0X00-0XFF (255) grade, and correspondence is different
Ambient light intensity；Step Q3 adjusts backlight illumination grade according to the classification of ambient light intensity, and stronger illumination is needed backlight
What is adjusted is stronger, while the contrast shown will also highlight the effect of background and display font, highlighted effect.Institute
Stating and adjusting display effect in step S4 further includes switching different background contrasts according to system time.Such as it can be according to white
It and night switch two different background contrasts, daytime background colour and display content contrast are transferred to higher position, night
Evening is by background colour and shows the more soft of content adjustment, convenient for driving observation road surface, eyes long-time observation is avoided to cause eye
Eyeball fatigue.
Step S5, content are shown, are carried out HUD content to the output information adjusted and are shown.By adjustment display effect, make
The display picture that must come back is more friendly intuitive, not will cause blind area, checks convenient for driver.
