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 to recover the display unit with the time according to the colour fading permeability variations curve
Normal display state.
8. rearview mirror control system as claimed in claim 7, it is characterised in that the rearview mirror is also included：Front photoreceptor, if
The front of the rearview mirror is placed in, the front photoreceptor is used for the front photosensitive value for sensing the rearview mirror；
The processor is additionally operable to judge whether the front photosensitive value of the front photoreceptor sensing is less than or equal to default front sense
Optical gate threshold value, when the front photosensitive value, which is more than this, presets positive photosensitive threshold value, determines that the second dazzle value is pre- not less than this
If dazzle threshold value.
9. rearview mirror control system as claimed in claims 6 or 7, it is characterised in that the rearview mirror is also included：Front is photosensitive
Device, is arranged at the front of the rearview mirror, and the front photoreceptor is used for the front photosensitive value for sensing the rearview mirror；
The processor is additionally operable to judge whether the front photosensitive value of the front photoreceptor sensing is more than default positive photosensitive threshold
Value, when the front photosensitive value, which is more than this, presets positive photosensitive threshold value, determines that the first dazzle value exceedes the default dazzle door
Threshold value.
10. rearview mirror control system as claimed in claims 6 or 7, it is characterised in that the processor is additionally operable to determine that environment is bright
Whether degree reaches default ambient brightness threshold value, when it is determined that the ambient brightness reach the default ambient brightness threshold value and this first
When dazzle value exceedes the default dazzle threshold value, first temperature value of the electric driven color-changing part is determined.
