Vehicle rear-view mirror - has antidazzle shutter moving in response to photodetector, detecting vehicle approaching from behind
DE 3041692 A1
Abstract
The rear view mirror has an antidazzle facility, having a shutter controlled by a photodetector connected to a control device that controls the shutter's servomotor. The control device is a comparator that compares a signal describing ambient light level with the light from the headlights of a vehicle approaching from behind. The two signals may be derived from the same photodetector or from two separate photodetectors. The signal describing ambient light level is used to suppress the operation of the antidazzle shutter.
