GeneralDuring nighttime driving, if a large difference in intensity exists between the surrounding light and the lightreflected off the inside rear view mirror from the headlights behind, an automatic glare-resistant EC (ElectroChromic) mirror automatically reduces the reflection rate of the mirror and thus dampens the glare from themirror.D This system uses 2 sensors (surrounding light detection sensor and rear light detection sensor) that arepresent in the inside rear view mirror to detect the difference between the intensity of light in theenvironment, and the light that the inside rear view mirror receives from the rear of the vehicle.D When the ignition*1/engine*2 switch is changed from OFF to IG-ON, this system defaults to AUTOmode.*1: Models without smart entry and start system*2: Models with smart entry and start system" System Diagram A2.

EC Mirror CellThe gel type EC elements are placed between a layer of transparent conductive coating, and a layer ofconductive reflector surfaces, which are placed between 2 sheets of glass. The EC elements have colorcoating characteristics. These characteristics are utilized to electronically very the mirrors reflection ratethrough the electro-chemical oxidation reduction reaction.4. Reflection Rate ControlThis CPU detects the surrounding light using its surrounding light detection sensor, the rear light using itsrear light detection sensor, and determines whether it is day or night based on the intensity of the surroundinglight. At the same time, the intensity of the glare from the rear is determined through the difference in intensitybetween the surrounding and rear light. In accordance with the intensity of the rear light, the reflection rateis varied steplessly. .
