An imaging system for a vehicle includes an imaging device having a field of view exteriorly and forward of the vehicle in its direction of travel, and an image processor operable to process the captured images in accordance with an algorithm. The algorithm comprises a sign recognition routine and a character recognition routine. The image processor processes the image data captured by the imaging device to detect signs in the field of view of the imaging device and applies the sign recognition routine to determine a sign type of the detected sign. The image processor is operable to apply the character recognition routine to the image data to determine information on the detected sign. The image processor applies the character recognition routine to the captured images in response to an output of the sign recognition routine being indicative of the detected sign being a sign type of interest.

Imaging system for vehicle

A vehicular video mirror system includes an interior rearview mirror assembly and a video display assembly. The interior rearview mirror assembly includes a mirror casing incorporating a reflective element. The mirror assembly further includes a mirror-mounting portion. The mirror casing is adjustable about the mirror-mounting portion for adjusting the rearward field of view of the reflective element. The video display assembly includes a video screen which is incorporated in a video display housing. The display housing is adapted to be adjustable about the display-mounting portion for adjusting the orientation of the video screen and, further, for moving the display housing to a stowed position whereby the video screen is generally not viewable by a driver when seated in a vehicle seat in the vehicle to thereby minimize the distraction to the driver of the vehicle.

Video mirror systems incorporating an accessory module

A forward-facing vision system for a vehicle includes a forward-facing camera disposed in a windshield electronics module attached at a windshield of the vehicle and viewing through the windshield. A control includes a processor that, responsive to processing of captured image data, detects taillights of leading vehicles during nighttime conditions and, responsive to processing of captured image data, detects lane markers on a road being traveled by the vehicle. The control, responsive to lane marker detection and a determination that the vehicle is drifting out of a traffic lane, may control a steering system of the vehicle to mitigate such drifting, with the steering system manually controllable by a driver of the vehicle irrespective of control by the control. The processor, based at least in part on detection of lane markers via processing of captured image data, determines curvature of the road being traveled by the vehicle.

A vehicular vision system includes a camera having a lens and a CMOS photosensor array having a plurality of photosensor elements. The camera is disposed at an interior portion of a vehicle equipped with the vehicular vision system. The camera one of (i) views exterior of the equipped vehicle through the windshield of the equipped vehicle and forward of the equipped vehicle and (ii) views from the windshield of the equipped vehicle into the interior cabin of the equipped vehicle. A control includes an image processor that processes image data captured by the photosensor array. The image processor processes captured image data to detect an object viewed by the camera. The photosensor array is operable at a plurality of exposure periods and at least one exposure period of the plurality of exposure periods is dynamically variable.

The present invention relates to electrochromic polymeric solid films, manufacturing electrochromic devices using such solid films and processes for making such solid films and devices. The electrochromic polymeric solid films of the present invention exhibit beneficial properties and characteristics, especially when compared to known electrochromic media. The electrochromic polymeric solid films are transformed in situ from a low viscosity electrochromic monomer composition by exposure to electromagnetic radiation, and in so doing minimum shrinkage occurs. The electrochromic polymeric solid films of the present invention also perform well under prolonged coloration, outdoor weathering and all-climate exposure, and provide an inherent safety aspect not known to electrochromic media heretofore.

The specification discloses a method for reducing current leakage and enhancing UV stability by using electrochemichromic solutions whose solvents include, either solely or in combination with other solvents, glutaronitrile (GNT).

Method for reducing current leakage and enhancing uv stability in electrochemichromic solutions and devices

An electro-optic reflective element assembly (510) includes a pair of substrates (512, 514) and an electro-optic medium (516) sandwiched therebetween. Each of the pair of substrates includes at least one conductive or semi-conductive layer (518, 520) disposed thereon. The electrical connections may electrically connect to a respective layer and may be electrically isolated from the other layer, such as via non-conductive regions (514e) of the substrates and/or deletion lines along one of the conductive layers. The pair of substrates may be positioned relative to one another such that overhang portions (512h, 512i) of the front substrate (512) extend beyond the corresponding edges of the rear substrate (514). The overlapping relationship may provide clearance for electrical connection to the conductive layers of the front and rear substrates such that the electrical connections are substantially not viewable through the front substrate.

Electro-optic reflective element assembly

The specification discloses electrochemichromic solutions and devices based on the use of from about 5% by volume of a nonpolymeric material having a high volume resistivity and high dielectric constant to reduce leakage current without unduly increasing solution viscosity. In an alternative aspect, high quantities of such materials are used even though solution viscosity increases to the point of preventing room temperature vacuum backfilling in order to take advantage of other features of such solutions.
