  • Patent number: 8203440
    Abstract: A vehicular vision system includes a photosensor array having a forward field of view to the exterior of the vehicle through the windshield of the vehicle. A portion of the photosensor array captures image data representative of an item of interest exterior the vehicle and within the forward field of view. A control is responsive to an output of the photosensor array and includes an image processor for processing the image data. At least responsive to the control analyzing the image data, the image sensing system senses the presence of an object within the field of view of the photosensor array, and the image sensing system, responsive at least in part to sensing the presence of the object, at least one of (i) controls a vehicle system using forward field of view information and (ii) supplements control of a vehicle system using forward field of view information.

  • Publication number: 20120140080
    Abstract: A video mirror system for a vehicle includes an interior rearview mirror assembly having an electrochromic reflective element and a video display screen disposed to the rear of the reflective element. The video display screen, when actuated, emits light that passes through a transflective mirror reflector of the reflective element to be visible to a driver of the vehicle viewing the reflective element. The video display screen includes a thin film transistor liquid crystal display element that is back lit by a plurality of white light emitting light emitting diodes. A camera having a field of view rearward of the vehicle is mounted at the rear of the vehicle and, during a reversing maneuver of the vehicle, a video output of the camera is displayed by the video display screen as video images so as to assist the driver in reversing the equipped vehicle.

  • Publication number: 20120053795
    Abstract: A vision system for a vehicle includes a first imaging sensor having a first forward field of view and a second imaging sensor spaced from the first imaging sensor and having a second forward field of view, which at least partially overlaps with the first forward field of view. A control processes image data captured by at least one of the first and second imaging sensors to determine an object present in the first and/or second forward fields of view. The control is operable to modulate a headlamp of the vehicle responsive to the processing of image data captured by the at least one of the first and second imaging sensors.
