Problems solved by technology

[0004] Some vehicle HUD concepts and applications proposed in recent years have planned to integrate lane indication and departure warning, adaptive cruise, real-scene navigation, advanced driver assistance system (ADAS), obstacle reminder, and even various entertainment and real-time comprehensive information in the car. Display and other functions are added to the HUD module, so that the driver cannot quickly obtain the corresponding driving information because the HUD displays more and more information
There are also various errors in the actual use of the car HUD, or different drivers driving the vehicle, so if the HUD only fixes one imaging area, it will affect the actual driver to view the HUD information

Embodiment 1

[0027] see figure 1 with figure 2 As shown, it is the optical path diagram and structural block diagram of the vehicle-mounted head-up display system with error calibration function of the present invention.

[0028] Such as figure 1 with figure 2 As shown, a vehicle-mounted head-up display system includes a control panel 1, a front windshield 2 and a head-up display 3 arranged in front of the front windshield 2, and the head-up display 3 includes an image generating unit 31 and several reflectors Mirror, the control panel 1 is connected with the image generation unit 31 for controlling the display image of the image generation unit 31, the display image forms a light beam, and is projected on the front windshield 2 after being reflected by the reflector , so that the driver observes the virtual image 6 of the displayed image.

[0029] Wherein, the head-up display 3 is installed on the vehicle instrument panel between the driving position and the front windshield 2; the ...

Embodiment 2

[0035]As described above, the vehicle-mounted head-up display system differs from this embodiment in that, as image 3 As shown, it is the optical path diagram of the vehicle-mounted head-up display system in this embodiment. A transmissive optical element 7 is arranged between the image generating unit 31 and the reflector, and the transmissive optical element 7 is arranged on the beam path of the first beam 51. , and only a part of the first light beam 51 is projected onto the mirror A 32 after passing through the transmissive optical element 7, and the rest of the first light beam 51 is emitted from the imaging production unit 31 and directly projected onto the mirror A 32, the transmissive optical element 7 is used to change the route of the light beam, so that the first light beam 51 is divided into two light beams and projected on the mirror A 32, and finally the display image sent by the same image generating unit 31 can present Two virtual images at different distances...

Embodiment 3

[0038] As described above, the vehicle-mounted head-up display system differs from this embodiment in that, as Figure 4 As shown, it is a diagram of the distribution area of ​​the display image of the vehicle-mounted head-up display system in this embodiment. The display image on the image generation unit 31 is divided into a main display area 311 and an auxiliary display area 312. The main display area 311 is generally Located in the middle of the image generating unit 31 or occupying most of the image generating unit 31 , the auxiliary display area 312 is located at the edge of the image generating unit 31 .

[0039] The content of the main display area 311 includes navigation information, ADAS, ACC, blind spot detection, obstacle recognition, lane warning warning (LDW), AR-HUD and other information combined with actual traffic conditions, thereby enhancing the driver's understanding of the actual driving environment. Perception; the content of the auxiliary display area 31...

Abstract

The invention provides a vehicle-mounted head-up display system having an error correction function. The vehicle-mounted head-up display system includes a control panel, a front windshield, an error correction unit and a head-up display. The head-up display includes an image generation unit and a mirror. A transmission optical element is arranged between the image generation unit and the mirror. The control panel is connected with the image generation unit, a display image of the image generation unit forms a light beam, and a virtual image is formed on the front windshield. The error correction unit is used to detect the virtual image, and a parameter of the image generation unit is adjusted to make the virtual image optimal. According to the vehicle-mounted head-up display system, the design of the transmission optical element is added, so that the image of two areas at different distances can be achieved on the basis of the single-light-path image generation unit; the error correction function is added, so that the application range of the head-up display system is wider, and it is also ensured that under different conditions, a driver can see clear images.

Description

technical field [0001] The invention relates to the technical field of motor vehicle head-up display systems, in particular to a vehicle-mounted head-up display system with an error calibration function. Background technique [0002] The Head Up Display (HUD) system was originally used on fighter jets. It can project some key flight mission information, such as altitude, speed, flight attitude, and radar fire control information, to the infinite distance in front of the pilot, and the fire control The information and the real scene outside the cockpit can be well fused and instructed. The pilot can grasp the situation information of himself and his surroundings and the enemy without leaving the observation of the situation outside the cockpit. For fighters with high nervousness It is very beneficial for pilots to complete combat missions. [0003] In the field of vehicles, with the development of vehicle electronic systems, more and more information needs to be synthesized ...
