Abstract:
A vehicular vision system includes at least one camera and an image processor. The camera is disposed at a vehicle and has an exterior field of view rearward of the vehicle. The camera is operable to capture image data. The image processor is operable to process captured image data. The vision system, responsive at least in part to image processing of captured image data, is operable to determine a trailer angle of a trailer that is towed by the vehicle. The vision system is operable to determine a path of the trailer responsive to a steering angle of the vehicle and the vision system is operable to display information for viewing by the driver to assist the driver in driving the vehicle with the trailer.
Abstract:
A vehicular camera includes a lens, a printed circuit board and an imager. The lens has a plurality of optical element and is disposed at a lens holder. The imager is disposed at the printed circuit board. The adhesive is initially curable in an initial radiation curing process that comprises exposure to UV light, and initially-cured adhesive is further curable to a further cured strength in a secondary thermal curing process. The adhesive is initially cured via the initial radiation curing process after the lens is brought into focus with the imager and is optically center-aligned therewith. The initially-cured adhesive, as cured via the initial radiation curing process, holds the lens optically center-aligned and in focus with the imager. After the initial radiation curing process, the lens holder, adhesively attached to one of the printed circuit board and the holding element, is moved to the secondary thermal curing process.
Abstract:
A vision system for a vehicle includes a rearward facing camera disposed at a rearward portion of a vehicle. With a trailer attached to the vehicle and rearward of the vehicle, a processor is operable to process captured images and, responsive at least in part to the processing, is operable to determine a plurality of trailer and vehicle-trailer interface parameters. The system is operable to calculate a calculated trailer angle based at least in part on calculations involving the parameters and a steering angle of the vehicle. Responsive to processing of images captured by the camera, the system is operable to determine a determined trailer angle of the trailer relative to a longitudinal axis of the vehicle. Responsive to the determined trailer angle and the calculated trailer angle, the system is operable to determine a degree of offset between the calculated trailer angle and the detected trailer angle.
Abstract:
A camera for a vision system of a vehicle includes a front housing portion, a circuit board and a rear housing portion. The front housing portion includes a lens and the rear housing portion includes first and second connectors for electrically connecting to a vehicle wire harness when the camera is disposed at a vehicle. The circuit board includes circuitry established thereat, with the circuitry being associated with an imager of the camera. The first connector includes a multi-pin connector portion having at least one terminal for electrically connecting to at least one first circuit element at the circuit board. The second connector includes a coaxial cable connector portion that receives a connecting end of a coaxial cable for electrical connection to at least one second circuit element at the circuit board. The first and second connectors are at least in part molded at the rear housing portion.
Abstract:
A vision system of a vehicle includes a camera disposed at an exterior portion of a vehicle and having a field of view exterior of the vehicle. The camera has a camera housing and a lens. A cover element is removably disposed at the camera. The cover element includes a curved transparent portion and a mounting portion. The curved transparent portion of the cover element, when the cover element is disposed at the camera, protects the lens so that the lens is not exposed to the environment external the vehicle. The cover element may be configured to be fixedly mounted at the exterior portion of the vehicle, such that the camera is removably mounted at the vehicle by detachable attachment at the cover element.
Abstract:
A camera module for a vehicle vision system includes a circuit element including an imaging sensor, associated circuitry and a circuitry connector. A cable has a cable portion and a cable connector for connecting to the circuitry connector. A housing portion includes a lens receiving portion and a cable receiving portion that mate together to substantially house the circuit element. The lens receiving portion includes a lens assembly. The cable receiving portion includes a connector receiving portion configured to receive and retain the cable connector therein and a wire receiving portion configured to receive and retain the cable portion therein. The tube has an appropriate form for a given cable shape and the tube encompasses at least a portion of the wire receiving portion and the cable portion. The tube substantially seals around the portion of the wire receiving portion and the cable portion.
Abstract:
A camera for mounting on a vehicle includes a front housing member, a rear housing member, a lens member mounted to the front housing member and an imaging element positioned to receive images from the lens member. A circuit board is mounted to the front housing member and is configured to send to another component signals relating to images received by the imaging element. The circuit board has at least one front electrical connector thereon. The rear housing member has at least one rear electrical connector extending therefrom, with the rear electrical connector electrically connected to the front electrical connector. The rear housing member has a rear alignment structure that aligns the rear electrical connector with respect to the front electrical connector. The rear housing member and the front housing member are unaligned and the rear housing member mates with the front housing member.
Abstract:
A vision system of a vehicle includes a plurality of cameras with exterior overlapping fields of view. The vision system is operable to calibrate at least one of the cameras and includes a plurality of targets disposed at locations near the vehicle and within the fields of views of the cameras. A display device is operable to display images captured by the cameras of the vision system. A plurality of user inputs may be provided and a user may selectively actuate the user inputs to manipulate images captured by the cameras to align portions of a target in overlapping regions of the captured images of adjacent cameras to calibrate the cameras. The vision system may calibrate cameras automatically, such as responsive to the targets moving into the fields of views of the cameras, whereby the vision system may calibrate the cameras as the vehicle is moved along an assembly line.
Abstract:
A vehicular driver monitoring system includes a camera disposed at a mirror head of an interior rearview mirror of a vehicle and viewing at least the head of a driver of the vehicle. The camera moves together and in tandem with the mirror head when the mirror head is adjusted by the driver of the vehicle to adjust a rearward view of the driver. Responsive to the driver of the vehicle adjusting the orientation of the mirror head, and responsive to processing at the ECU of image data captured by the camera, the vehicular driver monitoring system maintains the camera's view of at least the head of the driver as it was before the driver adjusted the orientation of the mirror head. The vehicular driver monitoring system, at least in part via processing at the ECU of image data captured by the camera, monitors the driver of the vehicle.
