The present invention relates to imaging systems or vision systems for vehicles.
Use of imaging sensors in vehicle imaging systems is common and known. Examples of such known systems are described in U.S. Pat. Nos. 8,324,552; 8,314,689; 8,222,588; 8,203,440; 7,994,462; 7,655,894; 7,339,149; 7,344,261; 7,459,664; 7,423,248; 6,097,023; 5,949,331; 5,670,935; and/or 5,550,677, which are hereby incorporated herein by reference in their entireties.
The present invention provides a vision system or imaging system for a vehicle that utilizes one or more cameras to capture images exterior of the vehicle, and provides the communication/data signals, including camera data or image data, which may be displayed or processed to provide the desired display images and/or processing and control, depending on the particular application of the camera and vision or imaging system. The present invention provides a camera module that houses an imager and lens holder and lens at the windshield of vehicle. The lens holder comprises enhanced attachment means or elements that attach the lens holder at the imager circuit board to mount the lens at the imager. Optionally, the lens may attach at the imager circuit board without use of a lens holder. The present invention provides a fastenerless surface mount or surface attachment of the lens or lens holder to the imager circuit board without use of additional or separate fasteners or screws. Optionally, the present invention provides a solder attachment of the imager circuit board to a housing of the camera.
These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.
The drawings illustrate, by way of example only, embodiments of the present disclosure.
A vehicular camera system can be installed on the inside of the front windshield of a vehicle, such as a car, truck, bus, or van. Such a camera system may be used for a variety of functions such as object detection, lane keeping, and high beam control.
As shown in
The lens holder assembly 16 is shown in more detail in
The lens holder assembly 16 as described requires an assembly step of attaching the lens holder 26 to the imager PCB 24, such as by fasteners or fastening screws 28 or the like. This attachment step requires time and separate additional fasteners and thus adds to the assembly process and cost. Additionally, a gasket 27 may be required to seal the image sensor 25 from dust and stray light.
The present invention provides an improved lens holder 30, which is shown in
As illustrated, the pins 33 may utilize “pin in paste” soldering and engage or receive or insert into the apertures in the PCB, whereby the ends 33 of the pins that protrude through the imager PCB may be soldered at the PCB to connect the lens retaining member 31 of lens holder 30 to the imager PCB 34. Optionally, in an alternative embodiment, the pins 33 may be angled and soldered onto pads on the imager PCB 34 so as to not require holes in or through the imager PCB 34.
Optionally, the lens retaining member 31 may be plated at its lower or PCB engaging end and then placed at a solder paste established on the imager side of the PCB. Then, when the lens retaining member 31 is placed at the PCB 34 and heated, it is soldered in place. After the lens retaining member or barrel is affixed at the imager PCB (either via the pins or plated end or the like), the lens is then placed and/or adjusted or set to actively align the lens with the imager.
The metal insert or retaining element of the lens holder may comprise any suitable configuration and may comprise a pin 33 or pins that protrude from the lens retaining member and are received into holes or apertures at or through the imager PCB when the lens holder is attached at the imager PCB. The lens retaining member thus may be “plugged” into the imager PCB and soldered or otherwise affixed thereat. Optionally, the lens retaining member may comprise apertures or hollow receivers that receive pins that protrude from the imager PCB, whereby the pins may be soldered at the PCB and, after they are received in the apertures of the lens retaining member, may be soldered or bonded or otherwise affixed at the lens retaining member. Optionally, the PCB or the lens retaining member may comprise an annular channel (such as a metallic annular shaped channel element that may be insert molded into the end of the lens holder) that receives a plurality of pins of the lens retaining member or the imager PCB therein at different locations around the circumference of the lens holder when the lens holder is disposed at and/or attached at the imager PCB. The various metal inserts or pins are configured to engage the PCB or protrude through the PCB or engage pins attached at the PCB, whereby the metal inserts are soldered at the PCB to affix the lens retaining member relative to the PCB.
Optionally, the plastic lens retaining member 31 preferably comprises an attachment feature (not shown) for mounting the lens holder assembly (comprising the lens 14, lens holder 30 and imager PCB 34) to a cover (such as to upper cover 12a, discussed above). The imager PCB 34 may then be held only by solder joints which connect pins 33 with the imager PCB 34.
Optionally, and with reference to
Thus, the present invention provides a lens holder that has an enhanced attachment at the imager PCB, thus providing a reduced cost and reduced processing assembly of the lens and imager and PCB. The lens holder attachment configuration of the present invention includes retaining elements that are insert molded into a plastic lens holding element or member and that comprise pins or retaining elements that engage and/or protrude through the imager PCB and that are soldered thereat to secure or retain or attach the lens holder at the imager PCB, without use of fasteners or screws. The present invention thus provides a fastenerless surface mount or surface attachment of the lens holder to the imager circuit board without use of additional or separate fasteners or screws. Thus, the present invention provides a camera assembly for a forward facing camera module of a vehicle that has fewer components and is easier to assemble.
Optionally, and as shown in
The lens or lens housing or assembly thus may have two or more pins or posts or pads for the PCB attachment or securement. The posts may be insert molded into the plastic housing or may be otherwise secured to the plastic housing (or to a metal housing or other substrate or material, depending on the camera application). Optionally, for a metallic lens housing or holder, the pins or posts may be incorporated into the housing design and formed with or as part of the metallic housing.
As can be seen with reference to
Optionally, the lens assembly of lens barrel may be attached or adhered directly to the circuit board, thereby obviating the need for the lens holder. For example, and with reference to
In the illustrated embodiment, the imager PCB 224 includes a pair of apertures or holes 224a at either side of the image sensor 225 (but they could be located elsewhere at the PCB) for receiving tabs 228a of the clips 228 to position the clips at the appropriate or selected or designed location at the PCB 224. The clips 228 also include attachment tabs or pads 228b that engage or contact solder pads or the like at the PCB 224 when the tabs 228a are received in the holes 224a of the PCB 224. Thus, and as can be seen with reference to
As shown in
The imager assembly of the present invention thus eliminates the need for a plastic lens holder. Instead, two steel clips are soldered or otherwise attached at the imager PCB and serve to attach the imager PCB to the housing of the camera. For example, the tabs 228c, 228d of the clips 228 may attach at or to respective tabs or bosses of the camera housing, such as via a fastener that may insert through the holes 228e in the tabs 228d of the clips 228. The UV-activated adhesive is dispensed directly onto the PCB, and the lens is adhered onto the PCB after it has been activated and aligned.
Optionally, it is envisioned that instead of using adhesive to attach the lens directly onto the PCB, the lens may be attached via piezo-electric elements. For example, the piezo-electric elements may be attached or soldered onto the PCB, whereby the lens may be adhered onto the piezo-electric elements. Using an auto-focus algorithm, a voltage may be applied to the piezo-elements while driving, whereby the piezo-electric elements may adjust the lens relative to the imager and PCB, thereby compensating for any defocusing or misalignment that may occur due to material expansion of the lens or PCB or other camera components that typically occurs with temperature or humidity changes.
Optionally, the forward facing camera may be disposed at or housed at a casing or module (such as at a windshield electronics module or the like) that is configured to attach at an interior or in-cabin surface of a vehicle windshield. Optionally, the module and camera may utilize aspects of the imaging systems and/or modules discussed above or such as described in U.S. Pat. Nos. 8,256,821; 7,946,505; 7,188,963; 7,004,593; 6,824,281; 6,968,736; 6,690,268; 6,250,148; 6,341,523; 6,593,565; 6,428,172; 6,501,387; 6,329,925; and 6,326,613, and/or in U.S. patent application Ser. No. 10/538,724, filed Jun. 13, 2005 and published Mar. 9, 2006 as U.S. Publication No. US-2006-0050018, and/or U.S. patent application Ser. No. 13/258,850, filed Sep. 22, 2011 (Attorney Docket DON01 P-1596), which are all hereby incorporated herein by reference in their entireties. Optionally, the forward facing camera may be disposed at a module that is spaced from the windshield, such as at or near or part of the interior rearview mirror assembly, or the forward facing camera may be disposed at or in the interior rearview mirror assembly that is attached at an in-cabin portion of the vehicle, while remaining within the spirit and scope of the present invention.
Optionally, the camera module or forward facing imaging (FFI) machine vision camera module may include a stray light shield that may include a light baffling or light trapping structure or configuration or system that limits or reduces extraneous light that passes through a window or windshield of the equipped vehicle from exterior the vehicle from being directly or indirectly imaged by the forward facing camera that is at or near the windshield and that views through the windshield.
Optionally, baffles or light baffling elements of the baffle configuration or structure may be disposed or established at a plate or substrate, which may be disposed at or in the module and may be arranged generally horizontally in front of and below the imaging sensor (or a lens or optical assembly of the imaging sensor or camera), with the baffles extending laterally in a cross car direction in front of the imaging sensor or camera. The baffles or light baffling elements may be generally vertically arranged at the plate or substrate or base of the baffle structure, so that the light baffling elements may be generally vertically oriented when the base of the structure is generally horizontally disposed at the vehicle (with selected angles of the opposite surfaces of the light baffling elements as discussed below).
The camera holder or module (including the camera and housing portion) may be configured to attach to a bracket that is attachable at the in-cabin surface of the vehicle windshield, such as via attachment to one or more attachment elements adhesively attached at the in-cabin surface of the vehicle windshield. The bracket may have an aperture for at least partially receiving and/or aligning with the camera and lens, such that the camera views through the windshield of the vehicle when the camera holder is attached at the bracket that is attached at the windshield. The camera holder and/or the bracket and/or a separate element provides a light shield having a wedge-shaped or tapered recess or pocket at the camera lens, whereby the camera views through the recess or pocket and through the windshield (such as by utilizing aspects of the camera systems described in U.S. Pat. Nos. 8,256,821 and/or 6,824,281, and/or U.S. patent application Ser. No. 13/470,860, filed May 14, 2012 (Attorney Docket DON01 P-1853), which are hereby incorporated herein by reference in their entireties). The wedge-shaped recess or pocket may be defined or formed by a base portion and opposite sidewalls that taper towards the lens and that extend generally upwards from the base portion to form the wedge-shaped recess or pocket between the in-cabin surface of the windshield and the base portion.
Because of the number of components established at the main circuit board of the camera module, it is desirable to have the main circuit board comprise a double sided PCB with circuitry and components established at both sides of the circuit board. The flexible connector or cable provides LVDS signals conveying image data captured by the imager to the image processor of the main circuit board. Alternately, image data captured by the imager may be conveyed to the image processor via the likes of Ethernet or by the protocols described in U.S. Pat. No. 7,697,027, which is hereby incorporated herein by reference in its entirety. The aperture or opening or hole in the main circuit board provides for passage of the flexible connector through the circuit board so as to establish electrical connection to the opposite side of the main circuit board, and the aperture or opening or hole in the main circuit board also at least partially receives a portion of imager assembly (such as a portion of the imager circuit board and/or imager and/or lens holder and/or lens) to provide a lower profile camera system or module.
Optionally, the camera module may include ventilation means for ventilating the module at the windshield (such as by utilizing aspects of the modules described in U.S. patent application Ser. No. 11/721,406, filed Jun. 11, 2007 and published Dec. 3, 2009 as U.S. Publication No. US-2009-0295181, and/or U.S. patent application Ser. No. 12/393,223, filed Feb. 26, 2009 (Attorney Docket MAG04 P-1504), which are hereby incorporated herein by reference in their entireties).
The camera or sensor may comprise any suitable camera or sensor. Optionally, the camera may comprise a “smart camera” that includes the imaging sensor array and associated circuitry and image processing circuitry and electrical connectors and the like as part of a camera module, such as by utilizing aspects of the vision systems described in International Publication Nos. WO 2013/081984 and/or WO 2013/081985, which are hereby incorporated herein by reference in their entireties.
The system includes an image processor operable to process image data captured by the camera or cameras, such as for detecting objects or other vehicles or pedestrians or the like in the field of view of one or more of the cameras. For example, the image processor may comprise an EyeQ2 or EyeQ3 image processing chip available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel, and may include object detection software (such as the types described in U.S. Pat. Nos. 7,855,755; 7,720,580; and/or 7,038,577, which are hereby incorporated herein by reference in their entireties), and may analyze image data to detect vehicles and/or other objects. Responsive to such image processing, and when an object or other vehicle is detected, the system may generate an alert to the driver of the vehicle and/or may generate an overlay at the displayed image to highlight or enhance display of the detected object or vehicle, in order to enhance the driver's awareness of the detected object or vehicle or hazardous condition during a driving maneuver of the equipped vehicle.
The vehicle may include any type of sensor or sensors, such as imaging sensors or radar sensors or lidar sensors or ladar sensors or ultrasonic sensors or the like. The imaging sensor or camera may capture image data for image processing and may comprise any suitable camera or sensing device, such as, for example, a two dimensional array of a plurality of photosensor elements arranged in at least 640 columns and 480 rows (at least a 640×480 imaging array, such as a megapixel imaging array or the like), with a respective lens focusing images onto respective portions of the array. The photosensor array may comprise a plurality of photosensor elements arranged in a photosensor array having rows and columns. Preferably, the imaging array has at least 300,000 photosensor elements or pixels, more preferably at least 500,000 photosensor elements or pixels and more preferably at least 1 million photosensor elements or pixels. The imaging array may capture color image data, such as via spectral filtering at the array, such as via an RGB (red, green and blue) filter or via a red/red complement filter or such as via an RCC (red, clear, clear) filter or the like. The logic and control circuit of the imaging sensor may function in any known manner, and the image processing and algorithmic processing may comprise any suitable means for processing the images and/or image data.
For example, the vision system and/or processing and/or camera and/or circuitry may utilize aspects described in U.S. Pat. Nos. 7,005,974; 5,760,962; 5,877,897; 5,796,094; 5,949,331; 6,222,447; 6,302,545; 6,396,397; 6,498,620; 6,523,964; 6,611,202; 6,201,642; 6,690,268; 6,717,610; 6,757,109; 6,802,617; 6,806,452; 6,822,563; 6,891,563; 6,946,978; 7,859,565; 5,550,677; 5,670,935; 6,636,258; 7,145,519; 7,161,616; 7,230,640; 7,248,283; 7,295,229; 7,301,466; 7,592,928; 7,881,496; 7,720,580; 7,038,577; 6,882,287; 5,929,786 and/or 5,786,772, and/or International Publication Nos.
