Vehicle-mounted HUD control method, device and system and readable storage medium

[0040] Please refer to figure 1 shown, figure 1 It is a schematic flowchart of the control method of the vehicle-mounted HUD in the present invention.

[0041] The present invention provides a method for controlling a vehicle-mounted HUD, comprising:

[0042] In step S110, it is detected whether sunlight is poured back on the TFT screen.

[0043] In one of the embodiments, it is determined whether there is a solar light backflow by detecting whether there is a backflow light spot on the TFT screen. Specifically, the optical principle of concave mirror magnification and projection is usually used in existing HUD products, that is, the principle similar to the convex lens is used to realize the magnification of the information on the TFT screen and after multiple refractions, and finally projected onto the specified transparent material, while the concave mirror or convex lens has The characteristic of focusing causes the sunlight to be poured back on the TFT screen when the ...

[0055] Please refer to figure 2 and image 3 shown, figure 2 and image 3 They are a schematic diagram of the structure of the control device of the vehicle-mounted HUD in the present invention and a schematic diagram of the installation of the control device of the vehicle-mounted HUD in the present invention.

[0056] The present invention provides a vehicle-mounted HUD control device, comprising: a light spot detection module 210, a light intensity detection module 220 and an anti-backflow control module 230, wherein:

[0057] The light spot detection module 210 is used to detect whether sunlight is poured back on the TFT screen.

[0058] The light intensity detection module 220 is used for detecting the intensity of sunlight poured into the TFT screen.

[0059] The anti-backflow control module 230 is used to determine whether sunlight backflow occurs and the sunlight intensity is greater than a preset value according to the detection results of the spot detection mod...

[0067] Please refer to image 3 shown, image 3 It is a schematic structural diagram of the control system of the vehicle-mounted HUD in the present invention.

[0068] The present invention provides a control system for a vehicle-mounted HUD, including a spot detection unit 310, a light intensity detection unit 320, and a control unit 330 electrically connected to the spot detection unit 310, the light intensity detection unit 320, and the TFT screen at the same time. in:

[0069] The spot detection unit 310 is used to detect whether sunlight is poured back on the TFT screen;

[0070] The light intensity detection unit 320 is used to detect the intensity of sunlight poured into the TFT screen;

[0071] When the detection value of the light spot detection unit 310 is greater than the preset value and the detection value of the light intensity detection unit 320 is greater than the preset value, the control unit 330 controls the TFT screen to shut down.

[0072] The control...
