Description

Technical Field

[0001] The present invention relates to the field of automobile rearview mirrors, and in particular to an intelligent streaming media interior rearview mirror system and a working method thereof. Background Art

[0002] With the continuous development of smart car technology, driver and occupant monitoring functions have become a key component to ensure driving safety and improve cabin comfort. Existing driver monitoring systems (DMS) and occupant monitoring systems (OMS) usually rely on physical rearview mirrors or other locations in the cabin for integration. The cameras of these systems are generally arranged at the A-pillar or steering column of the cabin, and rely on video signal lines to transmit image data to the vehicle host for processing. For example, the physical rearview mirror products produced by Magna have been mass-produced on Volkswagen models. Its DMS camera is integrated under the screen and only has DMS functions. However, existing solutions face some challenges: (1) Current DMS and OMS systems usually use two independent cameras to monitor the driver and occupants respectively, which not only increases the complexity of the layout of the power harness and video harness, but also increases the system cost. (2) Although the camera is arranged on the A-pillar, although this method can cover the driver's face, it occupies part of the space of the A-pillar and requires drilling holes on the A-pillar, which in turn affects the strength of the A-pillar and increases production costs. (3) If the camera is placed on the steering column, although it can save space on the A-pillar, this arrangement may affect the driver's field of view, especially the observation of the instrument screen. At the same time, the accuracy of the DMS may also be affected because the relative angle between the camera position and the driver's face is relatively fixed and cannot be flexibly adjusted according to the different postures of the driver. In addition, most existing technologies require the camera signal to be connected to the cockpit central control host through a video harness for processing, and rely on the computing power of the central control host to run and calculate the driver / passenger monitoring behavior algorithm, which will put pressure on the vehicle's computing resources and there will be computing delay problems.

[0045] First Embodiment

[0046] like Figure 1 Figure 2 As shown, this embodiment provides an intelligent streaming media rearview mirror system, including an outside rearview camera, an inside camera and a streaming media rearview mirror, and a streaming media rearview mirror ECU is integrated in the streaming media rearview mirror. This system provides high-definition rearview images, driver and passenger monitoring, and intelligent linkage functions through efficient hardware design, intelligent algorithms and advanced communication protocols. The inside camera is integrated on the streaming media rearview mirror to realize the driver / passenger monitoring function. The outside rearview camera is mainly used to provide a real-time video stream behind the vehicle and display the rearview image for the streaming media rearview mirror. The streaming media rearview mirror ECU (electronic control unit) is the core control unit of the streaming media rearview mirror, which is responsible for receiving and processing image data from outside and inside cameras, and integrates multiple functions such as image signal processing (ISP), DMS / OMS algorithm processing, and display control.

[0047] like Figure 1 As shown, in terms of appearance, the in-cabin camera is arranged at the lower jaw of the streaming media rearview mirror, at the Y0 position of the entire streaming media rearview mirror structure. Different from the traditional DMS / OMS arrangement, the traditional solution requires opening holes near the A-pillar, steering wheel column, and ceiling light to install the camera, which will affect the beauty and structural integrity of the interior. In this embodiment, the in-cabin camera is integrated into the streaming media rearview mirror, which can not only effectively capture the facial features and behaviors of the driver and passengers in the cabin, but also effectively avoid opening holes and making some structures on the interior to place the camera, thereby not affecting the integrity and simplicity of the interior. In terms of hardware, the in-cabin camera and the ECU of the streaming media rearview mirror are integrated in the same module. The in-cabin camera uses OV's OX05B1S IR / RGB dual-mode camera, which is connected to the streaming media rearview mirror ECU through the board-side MIPI signal to ensure efficient data transmission. The ECU is equipped with a DMS / OMS algorithm, which can process the image data collected by the in-cabin camera in real time and supports two working modes: IR (infrared) and RGB (visible light). Among them, the IR mode is used for the driver monitoring system (DMS), which mainly analyzes the driver's eye movements, facial expressions and other features. In addition to recognizing the face ID, it can also determine whether there are safety hazards such as fatigue driving or distracted driving (supporting smoking, drinking, and phone call monitoring), and can also automatically adjust the air conditioning vents according to the person. The RGB mode is used for the occupant monitoring system (OMS), which takes photos and videos of the occupants, monitors the facial expressions, gestures and other behaviors of the occupants in the car, such as detecting whether there are any objects left by the occupants or detecting the safety of children. After receiving the image signals from the in-cabin camera and the out-cabin rearview camera, the streaming media rearview mirror ECU performs ISP processing and DMS / OMS algorithm analysis, and sends the processed signals to the central controller (CDC) through the CAN bus for display.

[0048] The rearview camera outside the cabin is set at the rear of the vehicle, responsible for collecting real-time images behind the vehicle, and connected to the streaming media rearview mirror ECU through the LVDS harness or Fakra video interface to transmit high-definition video signals to it. After receiving the video signal, the ECU performs ISP processing and transmits the signal to the streaming media rearview mirror display. In addition, the streaming media rearview mirror ECU and the CDC central control host can transmit and interact with data through the integrated CAN communication module, thereby realizing the control and setting of the rearview mirror.

[0049] The streaming media rearview mirror ECU exchanges information and communicates with other ECUs through the CAN bus, and the ECU supports an Ethernet interface, which can be connected to the central gateway in the car, and the video of the camera in the cabin can be pushed to other ECUs connected to the central gateway controller in real time, so as to realize the communication between the streaming media rearview mirror and other control domains in the cockpit, so that the functions of the streaming media rearview mirror can be greatly expanded compared with other streaming media rearview mirrors. The CAN bus and Ethernet communication protocol between the streaming media rearview mirror ECU and the central control unit (CDC) realizes the linkage function between the streaming media rearview mirror display screen and the instrument screen, central control screen, and HUD screen in the cabin. At the same time, the ECU supports OTA (Over-The-Air) firmware upgrades through Ethernet to ensure that the rearview mirror system can be updated at any time to enhance functions and performance.

[0050] It can be seen that this technical solution uses an ECU with computing power on the media rearview mirror and an IR / RGB dual-mode camera to realize the driver / passenger monitoring function, so that the streaming media rearview mirror can have the ability to process algorithms independently, and can also drive the streaming media rearview camera to display the streaming media rearview picture, realizing a standard ECU software. The in-cabin camera uses OV's OX05B1S IR / RGB dual-mode camera, which is connected to the streaming media rearview mirror ECU through the board-side MIPI signal, and the out-cabin rearview camera is connected to the streaming media rearview mirror ECU through the LVDS wiring harness; the driver monitoring, passenger monitoring and streaming media rearview mirror rearview camera video signals are isolated in hardware and do not interfere with each other.

[0051] like Figure 2As shown, in addition to the in-cabin camera, the streaming media rearview mirror also includes a combined display screen 1, a hood 2, a front shell 3, a rear shell 9, an LED-PCBA, a main PCBA (4), a heat sink, a camera PCBA (6), a lens bracket 5, a ball head base 7 and a ball head cover 8, etc., wherein the combined display screen 1 is formed by fully bonding a glass cover plate and an LCD display screen by OCA glue, and is responsible for displaying the image output of the streaming media rearview mirror, providing high-definition rearview images and other vehicle information. The hood 2 is used to reduce the reflection of external light sources on the display screen, optimize the display effect, and ensure that the image is clearly displayed even under strong light. The front shell 3 and the rear shell 9 serve as the external protection structure of the streaming media rearview mirror, protecting the internal electronic components from external impact, and fixing the entire structure through the bayonet to ensure the overall stability of the product. The LED-PCBA is responsible for controlling the LED lighting part of the streaming media rearview mirror, providing a uniform backlight for the mirror surface, and ensuring the clarity of the image in a low-light environment. The main PCBA (4) and the camera PCBA (6) are the main components of the streaming media rearview mirror ECU. The main PCBA (4) is a core circuit board with an integrated image signal processing (ISP) function, which is responsible for processing the image signals collected by the external and internal cameras, and pushing the processed data to the LCD display for display. The heat sink provides heat dissipation for the main PCBA and other high-power electronic components, keeps the system running stably, and prevents overheating. The camera PCBA (6) is an integrated image sensor and signal processing unit, which is responsible for collecting image data from the internal camera and the external rearview camera, and transmitting the image signal to the main PCBA for processing. The lens bracket 5 is used to fix the lens and sensor board of the camera, ensuring that the camera is stable and accurately captures the image. The ball head base 7 and the ball head cover 8 are fixed by screws, providing an adjustable installation method for the streaming media rearview mirror, allowing the rearview mirror to adjust its angle according to the driver's needs. The connector 11 includes a power connector, a video connector and an Ethernet connector, which are installed on the ball head rod 10 by snaps, and is responsible for providing power and data transmission interface for the streaming media rearview mirror.The assembly process includes the following steps: (1) the ball head cover 8 is fixed to the ball head base 7 by screws; (2) the ball head rod 10 is inserted into the ball head base 7, and the ball head base 7 is reversely fixed to the rear shell 9 by screws, and the protruding jaw structure under the rear shell 9 is used to install the in-cabin camera; the power connector, the video connector and the Ethernet connector are installed on the ball head rod 10 by buckles; (3) the glass cover plate is fully bonded to the display screen by OCA glue to form a combined display screen 1, and the main PCBA (4) is fixed to the display screen and the display screen by screws. The screen and the glass form an integrated assembly; (4) the heat sink is fixed to the main PCBA (4) by screws; (5) the glass assembly is fixed to the front shell 3 by gluing, and the sunshade 2 is clamped to the front shell 3 by a bayonet; (6) the front cabin camera is fixed to the camera bracket 5 by AA glue, the IR light board and the camera sensor board are fixed to the camera bracket 5 by screws, and the camera bracket 5 is reversely fixed to the rear shell 9 by screws; (7) the front shell 3 and the rear shell 9 are clamped by a bayonet to complete the assembly of the entire rearview mirror structure.
