First Claim
Patent Images
1. A method for adjusting a reflectance of a mirror of a vehicle, the method comprising the steps of:
- identifying a characteristic of the vehicle;
determining an ambient light condition outside the vehicle;
determining a glare from the mirror; and
adjusting the reflectance of the mirror based on the characteristic, the ambient light condition, and the glare.

Abstract
Methods and systems are provided for adjusting a reflectance of a mirror of a vehicle. A first sensor measures an ambient light condition outside the vehicle. A second sensor measures a glare from the mirror. A controller identifies a characteristic of the vehicle, and adjusts the reflectance of the mirror based on the characteristic, the ambient light condition, and the glare.

17. A mirror assembly for a vehicle, the mirror assembly comprising:
-
a mirror having an adjustable reflectance; a first sensor configured to measure an ambient light condition outside the vehicle; a second sensor configured to measure a glare from the mirror; an input device configured to receive an input; and a controller coupled to the first sensor, the second sensor, the input device, and the mirror, the controller configured to; identify a characteristic of the vehicle using the input; select a relationship relating the reflectance, the glare, and the ambient light condition, based on the characteristic; determine an optimal reflectance based on the relationship using the glare and the ambient light condition as variable inputs; and adjust a voltage provided to the mirror in an amount that adjusts the reflectance of the mirror to equal the optimal reflectance. - View Dependent Claims (18, 19, 20)
