Abstract
A control apparatus for controlling the glare shield of a reflecting mirror of a vehicle, wherein the reflecting mirror is provided with on the upper half and lower half portions respectively first and second electro-optic elements whose transmittance of light being variable, and when a first photo detecting circuit determines that incident light on the reflecting mirror detected by an incident light detector is the direct sunlight, a first control circuit applies a voltage to the first electro-optic element to cause the upper half portion of the reflecting mirror to become a glare shield condition, and when a second photo detecting circuit determines that the incident light detected by an incident light detector is light of a headlight of a following vehicle, a second control circuit applies the voltage to the second electro-optic element to cause the lower half portion of the reflecting mirror to become the glare shield condition.
