In a specific example, the technical problem to be solved by the embodiments of the present invention is to provide a whole vehicle screen brightness adjustment scheme capable of meeting different user requirements, and is particularly suitable for a high-end vehicle type with a front row containing multiple screens. As shown in fig. 1 a:

The whole brightness adjustment has two realization modes, wherein the first mode is to set a hard switch for adjusting the brightness of the whole vehicle at the position of an instrument screen plate, and the second mode is to set a soft switch for adjusting the brightness through a multifunctional steering wheel in the instrument screen. The instrument screen sets the brightness according to the brightness setting input request of the hard switch or the soft switch, and simultaneously forwards the brightness request to the information entertainment host computer display screen, the auxiliary driving entertainment display screen and the air conditioner panel, so that the aim of integrally adjusting the height of the screen of the surrounding environment of the front-row driver by the brightness adjusting switch is fulfilled.
The brightness adjusting range of each screen is 0-100, the step length is 1, and the visual effect is stepless adjustment.
The hard switch travel can be set to 720 degrees in 2 weeks, and the gear is kept constant between 0 and 100. The soft switch and the multifunctional steering wheel are combined to adjust, so that the step size of the gear can be set to 5, and the brightness display value is 0, 5, 10 …, 90, 95 and 100 in 21 gears during soft switch adjustment.

The instrument screen, the infotainment host, the assistant driving entertainment screen and the air conditioner screen adjust the screen brightness according to the illumination intensity value input by the sunlight and rainfall sensor. The solar-rainfall sensor can divide the environment into night, dawn (including dusk, tunnel and tree shade) and day according to the measured visible light intensity and infrared light intensity. When the illumination intensity is lower than L1, the whole vehicle is in a night mode, the illumination intensity value measured by the sunlight and rainfall sensor is divided into N1 levels, and the value of N1 is determined by calibration. When the illumination intensity value is between [ L1, L2], the whole vehicle is in a dusk mode, the illumination intensity measured by the sunlight and rainfall sensor is divided into N2 levels, and the value of N2 is determined by calibration specifically; when the light intensity value is larger than L2, the whole vehicle is in a daytime mode, the light intensity value measured by the sunlight and rainfall sensor is divided into N3 levels, and N3 is determined specifically by calibration.
