Abstract:
A vehicular cabin monitoring system includes a mirror head adjustably attached at a mounting structure configured to attach at an interior portion of a vehicle. The mirror head accommodates a camera and a plurality of light emitting diodes (LEDs) connected in series with each other. A switch is operable in an open state, where current provided by a current driver passes through each individual LED of the plurality of LEDs, and a closed state, where current provided by the current driver passes through a first subset of LEDs of the plurality of LEDs and bypasses a second subset of LEDs of the plurality of LEDs. The switch operates in the open state when the camera captures image data for a first vehicular function, such as occupant monitoring, and operates in the closed state when the camera captures image data for a second vehicular function, such as driver monitoring.
Abstract:
A camera module for a vehicular vision system includes a metallic housing having a metallic upper housing portion and a metallic lower housing portion. A camera is accommodated in the housing and includes an imager circuit board having an imager thereat. The camera includes a lens barrel that protrudes through an aperture of the upper housing portion. A primary circuit board is accommodated in the housing and has an image processor that processes image data captured by the camera. A cooling fan is attached at the lower housing portion and directs airflow between heat dissipating fins of an outer side of the housing, with the heat dissipating fins being in thermal conductive connection via a thermal element with the image processor. The camera module is configured to be disposed at a vehicle windshield so as to have a field of view through the windshield and forward of the vehicle.
Abstract:
A vision system for a vehicle includes a camera disposed at the vehicle and having a field of view exterior of the vehicle. The camera includes an RGB photosensor array having multiple rows of photosensing elements and multiple columns of photosensing elements. An in-line dithering algorithm is applied to individual lines of photosensing elements of the photosensor array in order to reduce at least one of color data transmission and color data processing. The in-line dithering algorithm includes at least one of an in-row dithering algorithm that is applied to individual rows of photosensing elements of the photosensor array and an in-column dithering algorithm that is applied to individual columns of photosensing elements of the photosensor array. The in-line dithering algorithm may be operable to determine most significant bits and least significant bits of color data of photosensing elements of the photosensor array.
Abstract:
A vision system for a vehicle includes an image sensor disposed at a subject vehicle and having a field of view exterior of the subject vehicle. A control is operable to process image data captured by the image sensor to detect an object exterior of the subject vehicle. The control is operable to process captured image data to detect points of interest present in the field of view of the image sensor and, responsive to processing of captured image data, the control is operable to determine movement of the detected points of interest. The control is operable to process captured image data to determine movement vectors and, responsive to processing of captured image data, the control is operable to determine an object of interest in the field of view of the image sensor and exterior of the subject vehicle.
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 vehicular camera system includes an imager assembly that can include an imager disposed on an imager circuit board and a lens positioned to direct light to the imager. A main circuit board is operatively connected to the imager circuit board. The main circuit board can include at least one processor for processing images captured by the imager. The main circuit board has an opening, and at least a portion of the imager assembly extends through the opening.
Abstract:
A rear vision system for a vehicle includes a rearward facing camera disposed at a rearward portion of a vehicle equipped with the rear vision system. The rearward facing camera is operable to captures images 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 images 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 lane keeping system for a vehicle sets a safe zone in which the driver can drive the vehicle. If the system determines that the driver is at risk of leaving the safe zone, the system takes a corrective action, such as notifying the driver or applying a steering correction to the vehicle. The system adjusts the width of the safe zone depending on the driver's capability to stay within the safe zone. A lane centering system may be capable of autonomously steering the vehicle to remain within a lane. The lane centering system may include a controller that determines a target path for the vehicle depending on certain parameters. The controller may model each of the lane delimiters in a simplified form. This facilitates the determination of one of the target paths (the centerline of the lane). The simplified form may be a 3rd order polynomial equation.
Abstract:
In one aspect of the invention, a vehicular camera is provided, comprising a lens, a housing, an imager and a microcontroller that is capable of handling certain functions, such as applying overlays to images received by the imager, dewarping the image and/or providing different viewing modes.
Abstract:
A vehicular scalable integrated control system includes a plurality of cameras, a vehicular scalable integrated control unit, and a display screen for displaying video information to a driver of the vehicle. Visual image data captured by the cameras is processed by an image processor to detect objects in the fields of view of the cameras. The control unit determines a current geographical location of the vehicle and accommodates downloading of applications, which may include a tour guide application, with the tour guide application providing information associated with various geographical locations of a selected tour area. The control unit, responsive to a determination that the current geographical location of the vehicle is at a location identified in the tour guide application for the selected tour area, controls the display screen to display information associated with the identified location of the tour guide application and the current geographical location of the vehicle.
