As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
Vehicles are often equipped with cameras to aid in viewing areas surrounding the vehicles, as well as areas within the vehicle. These cameras may be integrated within the vehicle and configured to draw power from the vehicle's power supply, such as the vehicle's battery. These cameras may also communicate with the vehicle via a communication system within the vehicle. Often times additional cameras are desired for additional viewing areas, such as a rear seat of the vehicle or a rear exterior of the vehicle to view a towable item such as a trailer. However, after-market cameras are difficult to integrate with existing vehicle systems, can require a central communication module just for the cameras, can be costly to install, and can fail to provide sufficient quality images. Many of these systems have limited transmission distances, lack image quality, require a wired power source, require an additional mobile device application to be downloaded in order to synchronize with a vehicle head-unit, require an additional display in addition to the existing center stack display, etc.
Disclosed herein is a vehicle camera system having at least one camera assembly configured to be selectively installed in or on a vehicle. The camera assembly may have a separate communication component capable of interfacing with vehicle processors for easy pairing between the two devices. The camera assembly may be easily installed and removed so as to be movable from one location on a vehicle to another, and between multiple vehicles, trailers, etc. The camera assembly may be mounted on an exterior or an interior of the vehicle, and multiple mounting options are included in the assembly. The assembly may include a higher quality antenna to facilitate wireless communication between the camera assembly and the vehicle processor. The camera may also include a portable power source such as a battery. Due to the ease of set-up, this camera assembly may be easily configurable and desirable for aftermarket, factory installed, and factory invoiced markets. Thus, an easily configurable camera assembly is provided that increases the quality of images and communication, as well as allows for a user-friendly and less costly installation.
Multiple camera assemblies may be simultaneously used by the camera system and each may be connected with the vehicle processor and head-unit. A switchable view may be permitted at a display at the head-unit to provide a user with multiple viewing options and areas.
The vehicle 102 may include a head-unit 110. The processor 104 and memory 106 may be embodied in the head-unit 110. The head-unit 110 may include a display 114. The display 114 may be arranged within the vehicle dash board or center console. The display 114 may also include a heads up display (HUD). The display 114 may include a user interface (not separately shown), configured to receive user input. The display 114 may be configured to present information, images, and options to a passenger of the vehicle 102. Specifically, the display 114 may be configured to receive image data from one or more vehicle cameras and present images to the driver.
The processor 104 may include a wireless transceiver 116. The transceiver 116 may be a wireless radio configured to receive and transmit images and/or communications wirelessly with other compatible devices, such as a camera assembly 120, described herein. The transceiver 116 may be for example, a BLUETOOTH module, a ZIGBEE transceiver, a WiFi™ transceiver, an IrDA transceiver, an RFID transceiver, etc. The transceiver 116 may create a wireless network between the processor 104 and the camera assembly 120 in order to receive images wirelessly from the camera assembly 120. While the transceiver 116 is shown as being with the processor 104, the transceiver 116 may be embodied within the head-unit 110. Similarly, the head-unit 110 may include the processor 104, or may be in communication with the vehicle processor 104. More than one transceiver 116 may be included within the vehicle 102. The vehicle 102 may also include one or more antennas, communication networks, etc.
The camera system 100 may include at least one camera assembly 120 configured to capture images. As shown by way of example in
The interior camera assemblies 120 may provide images relating to the interior of the vehicle 102. In one example, the camera assemblies 120 may be arranged to view a rear seated child seat. The images from the camera assembly 120 may provide a visual to the driver of the child in the backseat. This may be especially helpful to parents as rear-facing child restraint systems are being used more frequently and for a longer duration.
Specific examples of the plurality of camera assemblies 120 may include a rear back-up camera 120a, a side mirror camera 120b, a front camera 120c, an interior vehicle camera 120d, and a rear trailer camera 120e. These examples are just that, and camera assemblies 120 may be arranged at a plurality of other locations around, in and on the vehicle 102 and trailer 122.
The camera assembly 120 is described in more detail with respect to
The camera assembly 120 may include an antenna 218 configured to transmit and receive wireless communications. The antenna 218 may be external, as illustrated by way of example in
The antenna 218 may interface with a communication component 238 to transmit and receive wireless communications. Camera assembly 120 may communicate with the transceiver 116 within the vehicle 102. The communication component 238 may be a Wi-Fi interface DCIO 3.0, a BLUETOOTH UART 802.11 operating at a 5 Ghz or 2.4 Ghz LAN protocol, for example. The antenna 218 may have a wide range, such as at least 70 feet. The communication component 238 is discussed in further detail below with respect to
The camera assembly 120 may include a mounting portion 230, or mounting element, configured to attach to various exterior and interior components of the vehicle 102. In one example, the mounting portion 230 may include an attachment mechanism such as a suction-cup configured to adhere to a smooth surface. In another example, the mounting portion 230 may include an attachment mechanism such as an adhesive. In another example, the mounting portion 230 may include magnetic attachment points. In still another example, the mounting portion 230 may include standard, or non-standard, bolt and receiving threaded receptacle.
The mounting portion 230 may affix the camera assembly 120 to the vehicle 102 in either a permanent or semi-permanent manner. Additionally or alternatively, the mounting portion 230 may temporarily affix the camera assembly 120 to the vehicle 102, allowing for the camera assembly 120 to be easily removable. In this example, the camera assembly 120 may be easily moved from one location on the vehicle 102 to another. For example, in one situation the driver may wish to affix the camera assembly 120 to the interior of the vehicle 102, facilitating a view of a rear seat. In another example, and during a subsequent trip, the driver may wish to affix the camera assembly 120 to an exterior of the trailer 122. Additionally, at certain times, the driver may wish to not use the camera assembly 120 and simply remove the assembly 120 from the vehicle 102. The camera assembly 120 may be installed and removed as desired, and even moved from one vehicle 102 or trailer 122 to another.
The camera assembly 120 may include a power component 220 configured to provide power to the camera assembly 120. The power component 220 may include various forms of power supplies such as the battery 212 and/or a direct power source 232, such as a wired AC power supply. The power component 220 may include a power management processor 234 configured to manage power supply. For example, the power management processor 234 may determine when to power the camera assembly 120 and when to not power the camera assembly 120. This may include powering down the assembly 120 during non-use (e.g., during non-drive times). The processor 234 may also determine to supply power during certain drive situations. For example, the processor 234 may elect to power the assembly 120 while the vehicle 102 is backing up, thus permitting the camera assembly 120 to provide imaging during this maneuver. The processor 234, in another example, may elect to power the assembly 120 when the vehicle 102 is in drive, but not when the vehicle 102 is in park.
The battery 212 may be rechargeable. The battery 212 may be recharged by an external power supply and may include a USB charging port at an interface 248.
The camera assembly 120 may further include the communication component 238. This may include the antenna 218. The communication component 238 may also include a WiFi™ Radio component 240 and a radio frequency front end (RF FE) component 242. The WiFi™ radio component 240 may facilitate communication between the vehicle processor 104 and the camera assembly 120 via WiFi™ communication protocols. The communication component 238 may interface with various antennas 258.
The RF FE component 242 may be configured to receive and process signals and provide the signals to the antenna 218. For example, the WiFi™ radio component 240 may implement the Institute of Electrical and Electronics Engineers (IEEE) 802.11.ac standard for communication and additionally allowing for communication via older 802.11 protocols including 802.11g and 802.11n. This standard permits beamforming which will in turn allow for long transmission distances at high bandwidths, allowing the camera assembly 120 to transmit image data at much greater distances than typical assemblies. The communication component 238 may also facilitate BLUETOOTH 5.0 technology to communicate with the vehicle processor 104. This may allow for improved audio/visual transmission distances, authentication, and increased image quality.
The vehicle head-unit 110 may, via the vehicle processor 104, include a software configured to provide various credentials. These credentials may include a vehicle specific two-dimensional code 252 or authentication image, such as a QR code, bar code, etc. The example vehicle code 252 shown in
During the initial set up, the user may place the camera assembly 120 in front of the display 114. The user may turn on the camera assembly 120, and capture an image of the vehicle code 252. The camera processor 210 may process the code 252 and use the code 252 to identify the vehicle 102.
Upon receiving the vehicle code 252, the camera assembly 120 may initiate pairing with the vehicle 102 via a wireless network 254. The wireless network 254 may be a WiFi™ network, BLUETOOTH, WLAN, etc. Security and encryption may be implemented via a WiFi™ protection setup (WPS) or WiFI Protected Access II (WPA-2). The camera may have the ability to act as an access point or the client to ensure that data transmitted over the wireless network 254 is secure and undetectable by third parties.
Notably, the camera system 100 may include multiple camera assemblies 120 which use the wireless network 254 supplied by the vehicle 102. The camera assemblies 120 may also interface directly with the vehicle processor 104 instead of having a central processor for just the camera assemblies 120. This allows for greater flexibility of installation locations, interchangeability within the camera system 100, etc. The camera assemblies 120 may be easily moved from one location to the next, and from one vehicle, trailer, etc., to another.
At block 510, the head-unit 110 may pair with the camera assembly 120 via the processes as described above with respect to
At block 515, once the camera assembly 120 is paired with the head-unit 110, the head-unit 110 may receive image data from the camera assembly 120 via the wireless network 254. The process 500 may continue until the camera assembly 120 is removed from the vehicle 102. The camera assembly 120 may he temporarily attached to the vehicle 102, as well as be moved from one vehicle to another.
