Step S22: and acquiring road condition information in front of the vehicle.
Specifically, the road condition information in front of the vehicle is obtained through the navigation information of the map navigation system, and/or the road condition information in front of the vehicle is obtained by analyzing the image obtained by the vehicle-mounted camera, and/or the point cloud model of the vehicle-mounted radar is subjected to 3D characteristic analysis, so that the road condition information in front of the vehicle is obtained.
Specifically, in one embodiment, the road condition information in front of the vehicle is periodically acquired according to a first preset time. For example, when the first preset time is 10 seconds, the traffic information in front of the vehicle is acquired every 2.5 seconds, and when the first preset time is 20 seconds, the traffic information in front of the vehicle is acquired every 5 seconds.
Step S23: and acquiring the time when the vehicle enters the dark environment according to the road condition information.
Specifically, the road condition information is analyzed to obtain the distance between the vehicle and the dark environment, and the driving time required for the vehicle to enter the dark environment is obtained according to the current vehicle speed or the average vehicle speed of the vehicle in a past period of time. Wherein, dark environment includes scenes such as tunnel, underground parking garage.
Specifically, in one embodiment, the traffic information is analyzed to obtain the congestion condition of the road ahead and the distance between the vehicle and the dark environment, and the driving time required for the vehicle to enter the dark environment is obtained according to the current vehicle speed or the average vehicle speed of the vehicle in the past period and the congestion condition of the road ahead.
Step S24: and judging whether the time for the vehicle to enter the dark environment is less than a first preset time.

Specifically, when the display brightness of the display is adjusted to the preset brightness, the brightness adjustment authority of the head-up display is taken over (that is, only the method for adjusting the display brightness of the display can adjust the display brightness of the head-up display), and the display brightness of the head-up display is adjusted to the preset brightness in advance, so that the view of the driver is prevented from being blocked by the display content with too high brightness when the driver enters a dark environment.
Specifically, in an embodiment, when the display brightness of the display is adjusted to the preset brightness, the brightness adjustment authority of the display on the driver side or the front row of the vehicle is taken over (that is, only the method for adjusting the display brightness of the display of the invention can adjust the display brightness of the display on the driver side or the front row of the vehicle) to adjust the display brightness of the display on the driver side or the front row of the vehicle to the preset brightness in advance, so that the eyes of the driver are prevented from being stimulated by excessively high display brightness when the driver enters a dark environment, the occurrence of visual fatigue is reduced, and the driving experience of the driver is improved.
Step S26: and controlling the display brightness of the display to be kept unchanged within a second preset time.
Specifically, timing is started after the display brightness of the display is adjusted to be the preset brightness, the display brightness of the display is controlled to be kept unchanged at the preset brightness within the second preset time, and the brightness adjustment authority of other vehicle control systems for the display is restored after the timing is finished (namely, the brightness of the display can be adjusted by other control systems after the timing is finished).
Specifically, in one embodiment, the second preset time is obtained according to a driving time required for the vehicle to enter the dark environment and a buffering time for the human eyes to enter the dark environment.
According to the method for adjusting the display brightness of the display, the road condition information in front of the vehicle can be obtained, the time when the vehicle enters the dark environment is obtained according to the road condition information in front, the display brightness of the display is adjusted in advance according to the time when the vehicle enters the dark environment, the phenomenon that the visual field of a driver is shielded by display content with too high brightness when the driver enters the dark environment is effectively avoided, and the driving safety is improved.
