Embodiment 1

[0036] The invention provides a method for adjusting the backlight of an intelligent rearview mirror, see figure 1 , the method includes:

[0037] 101. Collect external light intensity information;

[0038] In this step, the light-sensing chip, the light-sensing sensor or the brightness sensor collects the external light intensity information in a preset period, and performs sampling processing on the external light intensity information. The collected different light intensity information can be converted into different voltage values ​​and output to the baseband chip or the control system CPU. Generally, the higher the light intensity value, the larger the output voltage value, and the lower the light intensity value, the smaller the output voltage value.

[0039] 102. Determine the light intensity level corresponding to the external light intensity information, where different light intensity levels correspond to different backlight brightness of the smart rearview mirror;...

Embodiment 2

[0059] Embodiment 2 of the present invention provides a backlight adjustment system of an intelligent rearview mirror, such as figure 2 As shown, the system includes:

[0060] The collecting device 21 is used to collect the external light intensity information;

[0061] The determining device 22 is used to determine the light intensity level corresponding to the external light intensity information, wherein different light intensity levels correspond to different backlight brightness of the smart rearview mirror;

[0062] The adjustment device 23 is configured to adjust the brightness of the backlight according to the light intensity level corresponding to the external light intensity information.

[0063] Wherein, the collection device 21 may be a photosensitive chip, a photosensitive sensor or a brightness sensor. The determining device 22 and the adjusting device 23 may be a baseband chip or a control system CPU.

[0064] The backlight adjustment system of the smart rea...

Abstract

The invention discloses a backlight adjustment method of an intelligent rearview mirror and a system thereof and relates to the vehicle illumination technology field. The backlight adjustment method of the intelligent rearview mirror comprises the following steps of collecting outside light intensity information; determining a light intensity grade corresponding to the outside light intensity information, wherein the different light intensity grades correspond to different backlight brightness of the intelligent rearview mirror; and according to the light intensity grade corresponding to the outside light intensity information, adjusting the backlight brightness. By using the backlight adjustment method of the intelligent rearview mirror and the system thereof, according to the outside light intensity information, the backlight brightness of the intelligent rearview mirror can be automatically adjusted; manual adjustment is not needed and a driving risk is reduced; and intelligent rearview mirror energy consumption can be effectively reduced and usage time of an automobile storage battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle lighting, in particular to a method and system for adjusting a backlight of an intelligent rearview mirror. Background technique [0002] With the continuous advancement of automobile technology, the safety and convenience of automobile driving have attracted more and more attention. During the driving process of the user, the brightness of the external environment may change, such as driving out of a tunnel, etc. The change of the external brightness may cause the driver to be unable to see the image displayed on the LCD behind the rearview mirror. During the driving process, the LCD brightness is adjusted manually, which increases the safety hazard. Contents of the invention [0003] In view of this, the present invention provides a method and system for adjusting the backlight of an intelligent rearview mirror to solve the technical problem in the prior art that hidden safety hazards arise d...
