The permeability variations curve of the fixed electric driven color-changing part, the back of the backlight module is adjusted according to the permeability variations curve at any time
Brightness is to compensate the display brightness of the display unit.
7. rearview mirror control system as claimed in claim 6, which is characterized in that the processor is also used to determine the rearview mirror
The second dazzle value whether be less than the default dazzle threshold value；
When the second dazzle value is less than the default dazzle threshold value, the second temperature value of the electric driven color-changing part is determined；
The colour fading permeability variations curve of the electric driven color-changing part is determined according to the second temperature value；
Adjust the backlight illumination of the backlight module at any time according to the colour fading permeability variations curve to restore the display unit
Normal display state.
8. rearview mirror control system as claimed in claim 7, which is characterized in that the rearview mirror also includes: front photoreceptor, if
It is placed in the front of the rearview mirror, which is used to sense the front photosensitive value of the rearview mirror；
The processor is also used to judge whether the front photosensitive value of front photoreceptor sensing is less than or equal to default front sense
Optical gate threshold value determines that the second dazzle value does not surpass when the front photosensitive value is less than or equal to the default positive photosensitive threshold value
Cross the default dazzle threshold value.
9. rearview mirror control system as claimed in claims 6 or 7, which is characterized in that the rearview mirror also includes: front is photosensitive
Device is set to the front of the rearview mirror, which is used to sense the front photosensitive value of the rearview mirror；
The processor is also used to judge whether the front photosensitive value of front photoreceptor sensing is greater than the default photosensitive threshold in front
Value determines that the first dazzle value is more than the default dazzle door when the front photosensitive value is greater than the default positive photosensitive threshold value
Threshold value.
10. rearview mirror control system as claimed in claims 6 or 7, which is characterized in that the processor is also used to determine that environment is bright
Whether degree reaches default ambient brightness threshold value, when determine the ambient brightness reach the default ambient brightness threshold value and this first
When dazzle value is more than the default dazzle threshold value, first temperature value of the electric driven color-changing part is determined.
