Abstract

A vehicle vision system includes a bracket having an attachment portion configured to attach at an in-cabin surface of a vehicle windshield. The bracket includes a camera module attachment portion and at least one of (i) a rain sensor attachment portion and (ii) an interior rearview mirror assembly attachment portion. With the bracket attached at the windshield, a camera module is mountable to the bracket. When the camera module is mounted at the bracket attached at the in-cabin surface of the windshield, a stray light shield shields the image sensor array of the camera module from light emanating from within the vehicle cabin. At least when the camera module is mounted at the bracket attached at the windshield, the stray light shield is disposed at the camera module and a lens of the camera module views via the pocket through the windshield of the vehicle.
