    Abstract: A stationary vision system at a road along which vehicles travel includes an imaging sensor disposed at the road and having a field of view that encompasses a portion of the road. A wireless communication device is operable to wirelessly communicate with vehicles traveling along the road. A control includes a data processor operable to process image data captured by the image sensor. The control is operable to communicate with vehicles traveling along the road via the wireless communication device. The control, responsive to processing of image data captured by the imaging sensor, generates a three dimensional (3D) model of the portion of the road encompassed by the field of view of the imaging sensor. The control transmits the 3D model to vehicles traveling along the road.

    Abstract: A vehicular camera includes a housing having a front housing portion and a rear housing portion, with the front housing portion including a lens barrel accommodating a lens assembly, and with the rear housing portion including a connector portion configured to connect to a wire harness of a vehicle. An imager circuit board is disposed in an inner cavity of the housing, with an imager disposed at a first side of the imager circuit board and in optical alignment with the lens assembly. The imager circuit board is retained in the inner cavity by a spring element that engages the rear housing portion and urges the imager circuit board relative to the rear housing portion in a direction parallel to a longitudinal axis of the lens assembly and in a direction toward the lens barrel and the lens assembly.

    Abstract: A vision system for a vehicle includes a camera and a control. The control determines information on traffic signs and determines whether an indicated speed limit is for the lane being traveled by the vehicle. The vision system determines whether the indicated speed limit is for the lane being traveled by the vehicle responsive to a determination that the sign is at the left side of the lane and has an indicator representative of the right side of the lane and leaves the field of view at its left side, determination that the sign is at the right side of the lane and has an indicator representative of the left side of the lane and leaves the field of view at its right side, or determination of a speed limit sign at both sides of the road being traveled by the vehicle with both signs indicating the same speed limit.

    Abstract: A camera for a vehicle vision system includes a housing having a front housing portion with a lens barrel and lens assembly, and a rear housing portion with a connector. The front and rear housing portions are mated together to establish an inner cavity in the housing. An imager circuit board is disposed in the inner cavity of the housing, with an imager disposed at the imager circuit board and optically aligned with the lens assembly. When the front and rear housing portions are mated together, perimeter flanges of the front and rear housing portions may be curled to have multiple folds to seal the front housing portion relative to the rear housing portion. The imager circuit board may be held in the inner cavity by a spring element that urges the imager circuit board in a direction toward the lens assembly.

    Abstract: A method for assembling a vehicular camera includes providing a housing having a metal front housing portion and a metal rear housing portion. The front housing portion includes a lens barrel, and the rear housing portion includes a connector portion configured to connect to a vehicle wire harness. An imager circuit board is positioned at the front housing portion with an imager aligned with the at least one lens. The connector circuit board is retained via a spring element at a location spaced from the imager circuit board, with circuitry of the connector circuit board electrically connected to circuitry of the imager circuit board. The rear housing portion is joined with the front housing portion and the spring element engages the rear housing portion and the second side of the imager circuit board to retain the connector circuit board at the location spaced from the imager circuit board.

    Abstract: A vision system of a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. A tag or retroreflective element is disposed at another vehicle. With the camera disposed at the vehicle and when the tag element is present in the camera's field of view, an image processor is operable to process captured image data to determine a pattern of the tag element present in the field of view of the camera. The image processor compares the determined pattern of the tag element to a database of patterns and classifies the tag element at least in part responsive to determination that the determined pattern of the tag element generally matches a pattern of the database. The pattern of the tag element disposed at the other vehicle includes information pertaining to a type of the other vehicle.
