A vehicular exterior rearview mirror assembly includes a mirror reflective element assembly. The mirror reflective element assembly includes a main reflective element backing plate and a main reflective element. The main reflective element includes a glass substrate having a mirror reflector coated at a surface thereof. The mirror reflector-coated glass substrate of the main reflective element is attached at the main reflective element backing plate. The mirror reflective element assembly includes an auxiliary reflective element backing plate and an auxiliary wide angle reflective element. The auxiliary wide angle reflective element is positioned on the auxiliary reflective element backing plate. The auxiliary reflective element backing plate is attached to the main reflective element backing plate via an attachment mechanism.

A camera monitoring system for a vehicle includes an interior rearview mirror assembly with a video display screen disposed behind the interior mirror reflective element. The video display screen is operable to display video images derived at least in part from image data captured by at least one video camera of a plurality of video cameras of the equipped vehicle. Image data captured by at least a driver-side viewing video camera and a passenger-side viewing video camera is provided to an image processor and is processed by the image processor to detect vehicles present exterior of the equipped vehicle. Responsive at least in part to detection of another vehicle, video images derived at least in part from image data captured by the driver-side viewing video camera, a rear viewing video camera and/or the passenger-side viewing video camera are displayed by the video display screen.

A vehicular camera system includes a black-out layer disposed at an upper central region of a windshield as installed in a vehicle, an attachment member configured for attachment at the upper central region of the windshield where the black-out layer is disposed, and an accessory module including a camera. The accessory module is configured to detachably mount at the attachment member at the windshield such that the lens of the camera is spaced from the windshield, and such that the camera views forward of the vehicle through an aperture in the black-out layer via a tapered structure that is widest at the windshield and that tapers from the windshield towards where the lens of the camera is located. The tapered structure is at an acute angle relative to the vehicle windshield. The camera captures image data for a driver assistance system of the equipped vehicle.

An accessory system for a vehicle includes an attachment member attached at an interior surface of a vehicle windshield and an accessory module configured to detachably mount to the attachment member. The accessory module and attachment member are configured so that when the accessory module mounts to the attachment member, an electrical element of the accessory module is biased toward and against the inner surface of the windshield. The electrical element includes a camera and, with the accessory module mounted to the attachment member, the camera has a forward field of view through the windshield. The camera may be associated with at least one of (i) a headlamp control system, (ii) a lane departure warning system, (iii) an adaptive cruise control system, (iv) a sign recognition system, (v) a night vision system, (vi) a pedestrian detection system and (vii) a pre-crash avoidance system.

A mirror reflective element assembly for a vehicular exterior rearview mirror assembly includes a principal mirror element, a wide angle mirror element and an illumination element that at least partially circumscribes the wide angle mirror element. The illumination element emits illumination at least partially around the wide angle mirror element that is viewable by a person viewing the exterior rearview mirror assembly when the mirror assembly is disposed at a side of a vehicle. At least one of (i) the illumination element, responsive to determination that an ambient light level is below a threshold level, is operable to provide a light level that is less than about 100 candelas per square meter, and (ii) the illumination element, responsive to determination that an ambient light level is above a threshold level, is operable to provide a light level that is greater than about 200 candelas per square meter.
