The invention discloses a self-adaptive control working method for a vehicle-mounted instrument screen. The self-adaptive control working method comprises the following steps: S1, establishing a self-adaptive control system; s2, adjusting the brightness according to a self-adaptive control system; s3, determining the current environment of the vehicle; s3-1, current time information and coordinate positioning information are obtained through the MCU, and whether the vehicle is in a daytime state or a night state is judged according to the current time zone and the time information; s3-2, determining the adjustable range of the screen brightness in the daytime state; s3-3, determining the adjustable range of the screen brightness in the night state; s3-4, in the daytime state, the brightness of the current external natural light is obtained in real time through a photosensitive chip, and the brightness of the screen is adjusted through an LED backlight module according to the obtained brightness of the natural light; and S3-5, in a night state, when the time is at night, the brightness of the current external natural light is obtained in real time through the photosensitive chip, and the brightness of the screen is adjusted through the LED backlight module according to the obtained brightness of the natural light. The brightness of the instrument display screen can be automatically adjusted, and intelligence and high efficiency are achieved.

    本发明公开了一种车载仪表屏自适应控制工作方法,包括以下步骤:S1:组建自适应控制系统;S2:根据自适应控制系统进行亮度调节;S3:确定车辆当前所处环境;S3‑1:通过MCU获取当前时间信息和坐标定位信息,根据当前所处时区和时间信息判断处于白天状态还是夜晚状态;S3‑2:确定白天状态下屏幕亮度的可调节范围;S3‑3:确定夜晚状态下屏幕亮度的可调节范围;S3‑4:当处于白天状态时,通过光敏芯片实时获取当前外部自然光的亮度,并根据获取的自然光亮度,通过LED背光模块调节屏幕亮度;S3‑5:当处于夜晚状态时,当时间处于通过光敏芯片实时获取当前外部自然光的亮度,并根据获取的自然光亮度,通过LED背光模块调节屏幕亮度。能够自动对仪表显示屏幕的亮度进行调节,智能高效。
