Problems solved by technology

However, if the brightness level is adjusted directly according to the current lux value, there may be a problem, that is, the brightness level may be directly switched from a very low level to a very high level. For example, when driving out of a tunnel, the inside of the tunnel is very dark. The light outside the tunnel is very strong; and if the speed of the car is fast under the street lights at night, it may cause the problem of switching brightness back and forth.
These may affect the driver's vision and affect driving safety
[0004] In addition, when the vehicle is driving, the road surface is uneven, causing the vehicle to bump. The light sensor may produce abnormal values ​​of light perception, which will also affect the brightness adjustment. Therefore, the existing brightness switching cannot meet the user's requirements and affect the user. Experience

Abstract

The invention discloses a method for automatically and smoothly switching brightness based on an optical machine. The method comprises a step of sampling a light sensation lux value by using a set time interval, a step of performing abnormal value removing processing on the multiple sampled light sensation lux values to obtain light sensation lux values which is subjected to removing, and a step of smoothing the light sensation lux values is subjected to removing to obtain smoothed data, and adjusting the brightness of head-up display according to the smoothed data. A technical scheme providedby the invention has a high user experience.

Description

technical field [0001] The invention relates to the fields of electronics and vehicles, in particular to a method for smooth switching of automatic brightness based on optics and a vehicle and a vehicle terminal. Background technique [0002] Devices with a screen or light engine generally have an automatic brightness adjustment function, which can automatically adjust the brightness of the device screen or the brightness of the light machine according to the current light brightness of the device to bring the best visual effect to the user. As a vehicle-mounted intelligent terminal, for complex road conditions during driving, such as: entering a dim tunnel, driving out of a dim tunnel to a brightly lit road, an environment where there are street lights at intervals of tens of meters at night, and so on. [0003] The light sensor will calculate the current lux value according to the surrounding environment, and then use the lux value to adjust the brightness level of the scr...
