Embodiment Construction

[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0041] The present invention provides a vehicle HUD backlight adjustment method and device, the purpose of which is to overcome the inability of the prior art vehicle HUD200 (Head Up Display) to adjust the backlight brightness according to the use environment, thereby failing to achieve the purpose of energy saving and consumption reduction. Increasing the possibility of heating, affecting the user's use, long-term fixation is not conducive to eye health, and the defect that the backlight brightness adjustment curve is fixed and affecting the user's experience. By adjusting the brightness of th...

Abstract

The invention discloses a vehicle HUD backlight adjusting method and apparatus. The method includes acquiring the ambient light intensity of a vehicle HUD and converting the ambient light intensity into a digital signal; identifying and forwarding the digital signal; outputting a PWM signal based on the identified digital signal; and converting the PWM signal into the corresponding voltage signal to adjust the backlight intensity of the vehicle HUD. The vehicle HUD backlight adjusting method and apparatus can meet the needs of different user groups, play a role in energy saving, heating reduction, eyesight protection, and meanwhile facilitate driving safety.

Description

Technical field [0001] The present invention relates to the field of vehicle-mounted intelligent equipment, and more specifically, to a method and device for adjusting vehicle HUD backlight. Background technique [0002] Most of the traditional car products (such as car machines, PNDs, rearview mirrors, etc.) do not have the function of automatically adjusting the backlight. They can only be adjusted manually or according to the setting of the time period to distinguish between day and night scenes. Therefore, the existing products cannot achieve the purpose of energy saving and consumption reduction, and at the same time increase the possibility of heat generation, which affects the use of users, and long-term watching is not good for eye health. [0003] Although the existing mobile terminal backlight adjustment technology is relatively mature, the mobile phone program can automatically adjust the backlight brightness by collecting the light intensity value of the ambient light, ...
