Abstract:
A camera sub-assembly for a vehicular camera includes a cylindrical lens barrel and a lens holder. The cylindrical lens barrel is received in a cylindrical lens barrel receiving structure of the lens holder. An axial face of an annular flange of the cylindrical lens barrel is juxtaposed with an axial face at the outer end of the cylindrical lens barrel receiving structure of the lens holder with an adhesive disposed therebetween. An imager is disposed at a first side of an imager printed circuit board, which is attached at the lens holder. With the cylindrical lens barrel held in position relative to the imager by the adhesive, a frontmost optical element of a plurality of optical elements accommodated by the cylindrical lens barrel is distanced further from the imager than any other optical element of the plurality of optical elements. The frontmost optical element may be a glass lens element.
Abstract:
A method for backing up a trailer hitched to a vehicle includes mounting a rear backup camera at a vehicle and hitching a trailer at the hitch of the vehicle. Responsive to processing captured image data by a processor of the control, at least a portion of the trailer tongue of the trailer is detected using an edge detection algorithm. Responsive to processing at the control of image data captured by the rear backup camera during a backing up maneuver of the trailer hitched to the vehicle, trailer angle of the trailer relative to a longitudinal axis of the vehicle is determined. The control, based at least in part on trailer angle of the trailer, controls a steering system of the vehicle during the backing up maneuver of the trailer hitched to the vehicle to back up the trailer hitched to the vehicle along a rearward trajectory.
Abstract:
A vehicular vision system includes a camera, a distance sensor and a controller having at least one processor. Image data captured by the camera and sensor data captured by the distance sensor are processed at the controller. The controller, responsive to processing of captured image data and of captured sensor data, detects an object. The controller determines the distance to the detected object based at least in part on difference between the positions of the detected object in captured image data and in captured sensor data. The controller, responsive to processing of captured image data and of captured sensor data, and responsive to the determined distance to the detected object, determines that the detected object represents a collision risk. The controller alerts a driver of the vehicle of the collision risk and/or controls the vehicle to mitigate the collision risk.
Abstract:
A trailering assist system for a vehicle includes a rearward facing camera disposed at a rearward portion of a vehicle equipped with the trailering assist system. The rearward facing camera is operable to capture image data representative of the scene rearward of the equipped vehicle. When a trailer is near and/or attached to the equipped vehicle and is rearward of the equipped vehicle, a processor is operable to process the captured image data and, responsive at least in part to such processing, is operable to determine a trailer angle of the trailer relative to a longitudinal axis of the equipped vehicle.
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 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:
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.
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 vehicular vision system includes a side-viewing camera mounted within an exterior rearview mirror assembly attached at a side of a vehicle equipped with the vehicular vision system. The side-viewing camera has a field of view at least sideward of the side of the equipped vehicle at which the exterior rearview mirror assembly is attached. The side-viewing camera captures an image of a scene occurring exterior of the equipped vehicle. The captured image includes an image data set representative of the exterior scene. A control includes an image processor, and the image data set is provided to the control. The control processes a reduced image data set of the image data set provided to the control to detect edges present exterior of the equipped vehicle within an area of interest of the scene occurring exterior of the equipped vehicle that is within the field of view of the side-viewing camera.
Abstract:
A vehicular camera includes a front camera housing and a lens assembly having cylindrical barrel portion that is at least partially received at the front camera housing. An adhesive is disposed in an uncured state at the front camera housing and/or at the printed circuit board and laterally outboard of the imager. With the adhesive in the uncured state, an air gap exists between the inner surface of the lens and the imager. The adhesive is initially cured from the uncured state to an initially-cured state in an initial radiation curing process that comprises exposure to UV light for a first time period. With the adhesive in the initially-cured state, the front camera housing, with the printed circuit board adhesively attached thereto, is further cured to a further more cured state in a secondary curing process undertaken for a longer time period than the first time period.
