Abstract:
A vehicular vision system includes a camera and an image processor operable to process captured image data. When the vehicle is towing a trailer, and based at least in part on image processing of image data captured by the camera during maneuvering of the vehicle and the trailer, the vision system estimates a length of the trailer. Image data captured during maneuvering of the vehicle and the trailer includes image data captured when the vehicle is maneuvered with the trailer at an angle relative to the vehicle. The vision system, responsive at least in part to image processing of captured image data, determines a trailer angle of the trailer that is towed by the vehicle, and is operable to determine a path of the trailer responsive to a steering angle of the vehicle and the determined trailer angle of the trailer and the estimated length of the trailer.

Abstract:
A dynamic calibration method for calibrating a trailer angle detection system of a vehicle towing a trailer includes providing cameras configured to be disposed at the vehicle so as to have respective fields of view. Image data captured by at least some of the cameras is processed as the vehicle is driven forwardly and towing the trailer. A location of a portion of the trailer is determined via processing of captured image data. Responsive at least in part to processing of captured image data, a plurality of trailer parameters and vehicle-trailer interface parameters are determined. The plurality of trailer parameters and vehicle-trailer interface parameters are determined while the vehicle is driven forwardly and towing the trailer. The trailer angle detection system of the vehicle is calibrated responsive to determination that the trailer portion is not where the system expects it to be when the vehicle is traveling straight forward.
Abstract:
A method of assembling a vehicular camera includes providing a front camera housing and a lens assembly and dispensing an adhesive bead in an uncured state at at least one of (i) an attaching portion of the lens assembly and (ii) the front camera housing. The attaching portion and the front housing member are mated together with the adhesive bead therebetween. With the attaching portion and front housing member mated together, lens optics of the lens assembly are aligned with respect to an imaging array of the front camera housing. After such alignment, the adhesive bead is cured to a first cure level via ultraviolet light exposure to join the lens assembly and the front housing member. The lens assembly and front camera housing so joined are moved to a further curing station, where the adhesive bead is further cured to a second cure level.
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 method of assembling a vehicular camera includes providing a lens assembly having a base portion, a lens barrel and a plurality of optical elements in the lens barrel, and providing a circuit element having a circuit board and an imaging array. An adhesive bead is dispensed at the base portion and/or circuit element. The circuit element is placed at the base portion with the adhesive bead therebetween and the optical elements are aligned with the imaging array via a six axis robotic device when the circuit element is at the base portion and in contact with the adhesive bead. The adhesive bead is cured to a first cure level via exposure of the adhesive bead to ultraviolet light. The assembly is moved to a second curing stage and the adhesive bead is cured to a second cure level via heating the adhesive bead.
Abstract:
An imaging system for a vehicle includes an imaging sensor and a video display device. The imaging system generates an overlay that is electronically superimposed on the displayed images to assist a driver of the vehicle when executing a backup maneuver. The overlay has first, second and third overlay zones, with the overlay zones indicative of respective distance ranges from the rear of the vehicle to respective distances. As indicated to the driver viewing the video display screen when executing a backup maneuver, the first distance is closer to the rear of the vehicle than the second distance and the second distance is closer to the rear of the vehicle than the third distance. The first overlay zone may be a first color and the second overlay zone may be a second color and the third overlay zone may be a third color.
Abstract:
A vehicle vision system includes a camera configured to be positioned on a vehicle and a processing system operatively coupled to the camera. The processing system is operable to process image data captured by the camera. The image data is representative of a scene viewed by the camera. The processing system may further generate an image having three image panes including a central image pane derived from a first subset of captured image data and two side image panes derived from second and third subsets of captured image data. Each of the side image panes are shaped as parallelograms and arranged with respect to the central image pane to appear folded with respect to the central image pane. The processing system can output the image to a display for viewing by a driver of the vehicle.
Abstract:
A vehicular interior rearview mirror assembly includes a mirror head adjustably attached at a mounting base. The mirror head includes a mirror reflective element having a reflector-coated glass substrate having a front side and a rear side separated by a thickness of the glass substrate. A driver monitoring camera is accommodated by the mirror head and views through a camera region of the glass substrate of the mirror reflective element. A refraction-compensating element is disposed between a lens of the driver monitoring camera and the camera region of the glass substrate of the mirror reflective element. The refraction-compensating element has a first side and a second side that is not parallel to the first side. The refraction-compensating element offsets refraction of light that passes through the camera region of the glass substrate of the mirror reflective element.
Abstract:
A vehicular camera includes an imager, a housing having front and rear housing members, a lens member, and a circuit board. A female electrical connector assembly is disposed at the circuit board and includes a set of female electrical connectors. The rear housing member includes a male electrical connector having a set of electrically conductive pins. Each electrically conductive pin includes an inward-extending pin portion and an outward-extending pin portion. The outward-extending pin portions pass outward through a wall portion of the rear housing member into a socket connection portion of the rear housing member and the inward-extending pin portions extend inward from an inner surface of the wall portion of the rear housing member and plug into and electrically connect with respective female electrical connectors of the set of female electrical connectors when the rear housing member is mated with the front housing member.
