DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0047] Please refer to Figure 1 As shown in the drawings, in some embodiments, the present application provides an electronic rearview mirror system of a vehicle, which comprises a first electronic rearview mirror module and a second electronic rearview mirror module.

[0048] The first electronic rearview mirror module comprises a first image acquisition unit 1 for acquiring first image data and a first display unit 3 in communication connection with the first image acquisition unit 1.

[0049] The second electronic rearview mirror module comprises a second image acquisition unit 2 for acquiring second image data, a second display unit 4 in communication connection with the second image acquisition unit 2 and an image processing unit 5 integrated on a driving board of the second display unit 4.

[0050] The image processing unit 5 is configured to receive the first image data sent by the first image acquisition unit 1, process the first image data and send the processed first image data to the first display unit 3 for display, receive the second image data sent by the second image acquisition unit 2, process the second image data and send the processed second image data to the second display unit 4 for display.

[0051] In a specific embodiment of the present application, the first image acquisition unit 1 and the second image acquisition unit 2 are both wide-angle cameras, which are respectively used to acquire the rear view image of one side of the left side or the right side of the vehicle and are converted into image data and transmitted to the image processing unit 5. The image processing unit 5 is a SoC (System on Chip), and after the image processing unit 5 receives the first image data and the second image data from the first image acquisition unit 1 and the second image acquisition unit 2, the image processing unit 5 processes the image data through color correction, color restoration, distortion correction, etc., and then transmits the third image data formed by processing the first image data transmitted by the first image acquisition unit 1 to the first display unit 3 for real-time display, and transmits the fourth image data formed by processing the second image data transmitted by the second image acquisition unit 2 to the second display unit 4 for real-time display. The first display unit 3 and the second display unit 4 are one of an LCD display screen, an OLED display screen, or a TFT-LCD display screen.

[0052] In the present application, the image processing unit 5 integrated on the driving board of the second display unit 4 can process the image data acquired by the first image acquisition unit 1 and the second image acquisition unit 2, so that the first display unit 3 and the second display unit 4 share one image processing unit 5. Compared with the prior art in which two display units need to be equipped with two image processing units, the use of the number of image processing units 5 is reduced, and the hardware cost and maintenance cost of the system are reduced.

[0053] In the present application, the image processing unit 5 is integrated on the driving board of the second display unit 4, compared with the way of setting the image processing unit 5 independently of the first display unit 3 and the second display unit 4, the way of the present application can make the image processing unit 5 be installed together with the second display unit 4 after integration, which simplifies the installation procedure, reduces the demand for installation space, and facilitates the wiring setting between the second display unit 4 and the image processing unit 5.

[0054] In some embodiments, the electronic rearview mirror system of the vehicle can include more rearview mirror modules, and the more rearview mirror modules can share one image processing unit with the first electronic rearview mirror module and the second electronic rearview mirror module. In some embodiments, the electronic rearview mirror system of the vehicle further includes a microcontroller unit 6 (MCU) and a CAN transceiver 7. The microcontroller unit 6 and the CAN transceiver 7 are both integrated on the driving board of the second display unit 4. The microcontroller unit 6 is in communication connection with the image processing unit 5, and is used to process the third image data and the fourth image data received from the image processing unit 5 to form fifth image data, and transmit the fifth image data to the gateway 8 of the vehicle through the CAN transceiver 7.

[0055] Please refer to Figure 1 andFigure 2 As shown, in a specific embodiment, the image processing unit 5 is interconnected with the microcontroller unit 6 through a serial peripheral interface (SPI). The microcontroller unit 6 is interconnected with the vehicle gateway 8 through a CAN transceiver 7, and further interacts with the vehicle bus to connect the electronic mirror system with other vehicle systems such as BCM (Body Control Module) and VCU (Vehicle Control Unit).

[0056] The third and fourth image data outputted by the image processing unit 5 are transmitted to the microcontroller unit 6 through the SPI interface. The microcontroller unit 6 receives the third and fourth image data from the image processing unit 5, processes them to form fifth image data, and further analyzes these image data according to specific algorithms. For example, the microcontroller unit 6 can determine whether there is a potential safety threat (e.g. detecting an obstacle, lane departure), and prepare corresponding warning information. The microcontroller unit 6 formats the image data to be sent into fifth image data according to the requirements of CAN protocol. This includes image data packaging, priority setting, adding check bits, etc. to ensure that the fifth image data can be correctly transmitted on the CAN network. The microcontroller unit 6 then sends the formatted fifth image data packet to the gateway 8 through the external CAN transceiver 7, and the gateway 8 forwards it to the vehicle CAN bus. The CAN transceiver 7 is responsible for the signal conversion of the physical layer, converting digital signals into electrical signals suitable for CAN bus transmission. The fifth image data is placed on the CAN bus, which can be received by all nodes connected to the bus. This means that other vehicle systems (such as instrument panel, ADAS system, etc.) can obtain these information and take corresponding actions accordingly. The microcontroller unit 6 can also receive information from the vehicle bus through the CAN transceiver 7, such as status updates or control commands from other systems. These information can be used to adjust the operating mode of the image processing unit 5 or other system parameters. If necessary, the microcontroller unit 6 can forward the received information back to the image processing unit 5, so that the image processing unit 5 can adjust its processing strategy according to the latest situation. By using the microcontroller unit 6 as an intermediary, the data flow of the entire system is more orderly, and the burden of the image processing unit 5 directly communicating with the vehicle bus is reduced. Moreover, since many logical controls can be implemented directly on the microcontroller unit 6, such design is also beneficial for software updates and maintenance, without the need to frequently modify the image processing unit 5 firmware.

[0057] The CAN transceiver 7 and the gateway 8 are connected through CAN-H and CAN-L, so that the image data is transmitted by differential signals between the two, which can ensure reliable and efficient communication in an environment where there may be a large amount of electrical noise, improve the quality of data transmission, and enhance the overall stability and safety of the system.

[0058] Referring to Figure 1 As shown in some embodiments, the electronic rearview mirror system of the vehicle further comprises a deserializer 9 integrated on the driving board of the second display unit 4. The deserializer 9 is used to convert the serial first image data and second image data transmitted by the first image acquisition unit 1 and the second image acquisition unit 2 into parallel image data respectively, and then transmit the parallel image data to the image processing unit 5, so that the image processing unit 5 forms third image data and fourth image data according to the parallel image data.

[0059] Specifically, the deserializer 9 and the image processing unit 5 are connected through two MIPI_CSI (Camera Serial Interface) interfaces. The serial first image data transmitted by the first image acquisition unit 1 is converted into parallel image data by the deserializer 9 and then transmitted to the image processing unit 5 through one MIPI_CSI interface, and the serial second image data transmitted by the second image acquisition unit 2 is converted into parallel image data by the deserializer 9 and then transmitted to the image processing unit 5 through the other MIPI_CSI interface, so that the multiple processing cores or processing units on the image processing unit 5 can process the first image data and the second image data based on the first image acquisition unit 1 and the second image acquisition unit 2 at the same time, improving the efficiency and speed of processing.

[0060] In some embodiments, the electronic rearview mirror system of the vehicle further comprises a first LVDS (Low Voltage Differential Signaling) input line 10 connected between the first image acquisition unit 1 and the deserializer 9, and a second LVDS input line 11 connected between the second image acquisition unit 2 and the deserializer 9. The first image data transmitted by the first image acquisition unit 1 is transmitted to the deserializer 9 through the first LVDS input line 10. The second image data transmitted by the second image acquisition unit 2 is transmitted to the deserializer 9 through the second LVDS input line 11. The first image data to be transmitted between the first image acquisition unit 1 and the deserializer 9 and the second image data to be transmitted between the second image acquisition unit 2 and the deserializer 9 can be transmitted at a low voltage differential signal high speed, low power consumption and strong anti-interference through the corresponding LVDS input line.

[0061] In some embodiments, the electronic rearview mirror system of the vehicle further comprises a first FAKRA (abbreviation of German "Fachkreis Automobil") connector 12 and a second FAKRA connector 13. The first LVDS input line 10 is connected to the deserializer 9 through the first FAKRA connector 12 to transmit the first image data sent by the first image acquisition unit 1 to the deserializer 9, improving the convenience and stability of the connection between the first LVDS input line 10 and the deserializer 9. The second LVDS input line 11 is connected to the deserializer 9 through the second FAKRA connector 13 to transmit the second image data sent by the second image acquisition unit 2 to the deserializer 9, improving the convenience and stability of the connection between the second LVDS input line 11 and the deserializer 9.

[0062] In an optional embodiment, the male end of the first FAKRA connector 12 connects one end of the first LVDS input line 10, and the female end of the first FAKRA connector 12 is directly connected in communication with the deserializer 9. Through the plug-in connection between the male end of the first FAKRA connector 12 and the female end of the first FAKRA connector 12, the communication connection between the first LVDS input line 10 and the deserializer 9 can be quickly realized.

[0063] In an optional embodiment, the male end of the second FAKRA connector 13 connects one end of the second LVDS input line 11, and the female end of the second FAKRA connector 13 is directly connected in communication with the deserializer 9. Through the plug-in connection between the male end of the second FAKRA connector 13 and the female end of the second FAKRA connector 13, the communication connection between the second LVDS input line 11 and the deserializer 9 can be quickly realized.

[0064] In some embodiments, the electronic rearview mirror system of the vehicle further comprises a serializer integrated on the driving board of the second display unit 4, which is used to convert the parallel third image data and fourth image data processed by the image processing unit 5 into serial image data respectively and send them to the corresponding first display unit and second display unit, and then transmit them to the corresponding first display unit 3 and second display unit 4 at a high rate for display.

[0065] In some embodiments, the serializer includes a first serializer 14 and a second serializer 15. The first serializer 14 is arranged between the image processing unit 5 and the first display unit 3 and is connected to the image processing unit 5 through an HDMI (High-Definition Multimedia Interface) interface, so as to convert the third image data sent by the image processing unit 5 through the HDMI interface from parallel to first serial image data and then transmit the first serial image data to the first display unit 3 at a high speed and over a long distance. The second serializer 15 is arranged between the image processing unit 5 and the second display unit 4 and is connected to the image processing unit 5 through a MIPI_DSI (Display Serial Interface) interface, so as to convert the fourth image data sent by the image processing unit 5 through the MIPI_DSI interface from parallel to second serial image data and then transmit the second serial image data to the second display unit 4 at a high speed and with low power consumption for picture display.

[0066] By arranging the first serializer 14 and the second serializer 15 to transmit image data to the first display unit 3 and the second display unit 4 respectively, the image data transmitted to the first display unit 3 and the second display unit 4 can avoid sharing a serializer, thereby avoiding an increase in delay or a decrease in frame rate. Moreover, the use of two serializers can maintain the simplicity and consistency of the system architecture, and at the same time, leaves room for the addition of more display units or other extensions in the future.

[0067] In some embodiments, the electronic rearview mirror system of the vehicle further includes an LVDS output line 17 connected between the first serializer 14 and the first display unit 3, so that the first serial image data sent by the first serializer 14 can be transmitted to the first display unit 3 at a high speed through the LVDS output line 17 in the form of a low-voltage differential signal.

[0068] In some embodiments, the electronic rearview mirror system of the vehicle further includes a third FAKRA connector 16 for connecting the LVDS output line 17 with the first serializer 14. Through the use of the third FAKRA connector 16 in cooperation with the LVDS output line 17, the connection between the LVDS output line 17 and the first serializer 14 is facilitated, and the stability of the connection between the LVDS output line 17 and the first serializer 14 is improved.

[0069] In an optional embodiment, a male end of the third FAKRA connector 16 is connected to one end of the LVDS output line 17, and a female end of the third FAKRA connector 16 is connected to the first serializer 14. By inserting the male end of the third FAKRA connector 16 into the female end of the third FAKRA connector 16, the communication connection between the LVDS output line 17 and the first serializer 14 can be quickly realized.

[0070] In the embodiments of the present application, the positions of the two rearview mirror modules are not specifically limited and can be set according to actual needs. In some specific embodiments, the first image acquisition unit 1 is arranged on the first side of the vehicle, the second image acquisition unit 2 is arranged on the second side of the vehicle, the first display unit 3 is arranged on the first side of the vehicle interior, and the second display unit 4 is arranged on the second side of the vehicle interior. The first side and the second side are different sides of the vehicle and are one of the left and right sides of the vehicle.

[0071] For example, the first image acquisition unit 1 is arranged on the right side of the vehicle at the position of the rearview mirror, and the second image acquisition unit 2 is arranged on the left side of the vehicle at the position of the rearview mirror. Correspondingly, the first display unit 3 is arranged on the right side of the vehicle cabin at the A-pillar or the door edge, and the second display unit 4 is arranged on the left side of the vehicle cabin at the A-pillar or the door edge.

[0072] In the above position setting, the wiring needs to be set to improve the safety and aesthetics of the wiring of the electronic rearview mirror system of the vehicle. In specific embodiments, the first LVDS input line 10 is arranged along the interior of the instrument panel of the vehicle and extends from the first side of the vehicle to the second side of the vehicle interior, the second LVDS input line is arranged along the interior of the door of the vehicle (specifically the second side door) and extends from the second side of the vehicle to the second side of the vehicle interior, and the LVDS output line 17 is arranged along the interior of the instrument panel of the vehicle and extends from the second side of the vehicle interior to the first side of the vehicle. In this way, the first LVDS input line 10, the second LVDS input line 11 and the LVDS output line 17 are prevented from being exposed, thereby improving the safety and aesthetics of the wiring of the electronic rearview mirror system of the vehicle.

[0073] In some embodiments, the image processing unit 5 is interconnected with the deserializer 9, the first serializer 14 and the second serializer 15 through an IIC (Inter-Integrated Circuit) interface, so that the image processing unit 5 can send control commands and configuration parameters to the deserializer 9, the first serializer 14 and the second serializer 15 through the IIC interface to adjust their working modes, resolutions, frame rates, etc. The image processing unit 5 can also perform fault diagnosis through the IIC interface to quickly locate the problem, thereby facilitating maintenance and repair. The IIC interface provides a simple and flexible communication method between the image processing unit 5 and the deserializer 9, the first serializer 14 and the second serializer 15, which helps to reduce the cost of the system and improve the reliability of the system.

[0074] In some embodiments, the electronic rearview mirror system of the vehicle further comprises a DDR (Double Data Rate SDRAM) unit and a FLASH (memory) unit connected to the image processing unit 5 respectively, the DDR unit 18 is used to provide temporary data storage and processing capability for the image processing unit 5, and the FLASH unit 19 is used to store the image data processed by the image processing unit 5, so as to improve the overall performance and response speed of the image processing unit 5, so that the image processing unit 5 can process more complex images and image data, and the image data can still be kept without loss when the system is powered off.

[0075] In some embodiments, the electronic rearview mirror system of the vehicle further comprises a battery unit 20, which is used to supply power to each power-consuming unit (such as the image acquisition unit, the image processing unit 5 and the image transmission unit) in the electronic rearview mirror system of the vehicle. During use, an external power supply first sends a power supply signal to the battery unit 20, the battery unit 20 optimizes the power supply signal, and the battery unit 20 sends the optimized power supply signal to each power-consuming unit to provide stable voltage for each power-consuming unit.
