Abstract
A vehicle rearview mirror system suitable for use in a vehicle comprises an interior rearview mirror assembly, at least one control and, preferably, at least one exterior rearview mirror assembly. The interior rearview mirror assembly includes an interior electro-optic reflective element having an electrically variable reflectivity. The exterior rearview mirror assembly includes an exterior electro-optic reflective element having an electrically variable reflectivity. The at least one control at least controls a reflectivity level of the interior electro-optic reflective element, preferably in accordance with a duty cycle of a pulse width modulated signal. The at least one control may further control a reflectivity level of the exterior electro-optic reflective element via a bus system of the vehicle. The control or controls may communicate and/or control an accessory of the vehicle via the bus system of the vehicle. The controls may comprise a control node of a vehicle control network.
