In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present application. Instead, it is merely an example of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0036] The automobile electronic outside rearview mirror has the advantages of expanding the field of view, reducing the blind area, being less affected by bad weather environment, effectively reducing the wind resistance and wind noise, etc., and can well solve the problems of "not seeing all, not seeing clearly, being disturbed, and large wind resistance" of the traditional glass rearview mirror, thereby effectively improving the safety of driving.

[0037] Figure 1 It is a structural schematic diagram of an existing automobile electronic outside rearview mirror system. As shown in Figure 1 The existing automobile electronic outside rearview mirror system generally adopts a structure composed of a main controller 101, a left image acquisition unit 102, a right image acquisition unit 103, a left display screen 104, a right display screen 105, and a plurality of wire harnesses. The left image acquisition unit 102 and the right image acquisition unit 103 are respectively installed near the positions of the traditional rearview mirrors installed on the left and right sides of the vehicle body, the main controller 101 is generally placed at the bottom of the driver's seat or the bottom of the center console, and the display screens are installed on the left and right sides of the vehicle, for example, on the inside of the left and right doors, on the inside of the left and right A-pillars, or near the A-pillars.

[0038] The left image acquisition unit 102 and the right image acquisition unit 103 are used to acquire the rear view pictures of the left and right sides of the vehicle, transmit them to the main controller 101 for processing, and then display them on the left display screen 104 and the right display screen 105 respectively, thereby providing the driver with the rear view of the left and right sides of the vehicle body. The main controller 101 is connected with the left image acquisition unit 102, the right image acquisition unit 103, the left display screen 104, and the right display screen 105 through wire harnesses. Therefore, the existing automobile electronic outside rearview mirror system has many components and complex wiring.

[0039] Therefore, the present application provides a new automobile electronic outside rearview mirror system, which integrates the controller and the display screen into one component, reduces the components and wire harnesses, and reduces the wiring complexity.

[0040] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0041] Figure 2 This is a schematic diagram of the structure of an automotive electronic exterior rearview mirror system provided in an embodiment of this application. Figure 2 As shown, the system may include, for example, two sets of display devices. Each set of display devices includes: an exterior rearview mirror image acquisition unit and an electronic exterior rearview mirror display assembly; wherein the exterior rearview mirror image acquisition unit is connected to the electronic exterior rearview mirror display assembly.

[0042] In this embodiment, the exterior rearview mirror image acquisition unit is deployed on one side of the vehicle body, for example, near the mounting position of a conventional rearview mirror located outside the vehicle body, for acquiring images of the rear view on that side. Exemplarily, the exterior rearview mirror image acquisition unit can be a component equipped with any image acquisition sensor. The image acquisition sensor mentioned here can be, for example, a camera sensor.

[0043] The electronic exterior rearview mirror display assembly has control and display functions. It is used to receive rear view images acquired by the corresponding exterior rearview mirror image acquisition unit, and to process and display the rear view images. For example, this electronic exterior rearview mirror display assembly is typically deployed inside the vehicle and near the A-pillar or the front door, allowing the driver to easily observe the rear view on that side.

[0044] Generally speaking, refer to Figure 2 As shown, in one of the two sets of display devices, the exterior rearview mirror image acquisition unit (hereinafter referred to as the left exterior rearview mirror image acquisition unit 201) is deployed near the position where the traditional rearview mirror is installed on the left side of the vehicle body. It is used to acquire the rearview field image of the left side of the vehicle. The corresponding electronic exterior rearview mirror display assembly (hereinafter referred to as the left electronic exterior rearview mirror display assembly 203) is deployed inside the vehicle and near the left A-pillar or the left front door. It is used to receive the rearview field image acquired by the left exterior rearview mirror image acquisition unit, process and display the rearview field image of the left side of the vehicle, so that the driver can observe the rearview field situation on the left side through the electronic exterior rearview mirror display assembly.

[0045] In the two sets of display devices, the external rearview mirror image acquisition unit (hereinafter referred to as the right external rearview mirror image acquisition unit 202) in the other set of display devices is deployed near the position where the traditional rearview mirror is installed on the right side of the vehicle body. It is used to acquire the image of the right rearview field of view of the vehicle. The corresponding electronic external rearview mirror display assembly (hereinafter referred to as the right electronic external rearview mirror display assembly 204) is deployed inside the vehicle and near the right A-pillar of the vehicle body or near the right front door. It is used to receive the rearview field of view image acquired by the right external rearview mirror image acquisition unit, process and display the image of the right rearview field of view of the vehicle, so that the driver can observe the right rearview field of view through the electronic external rearview mirror display assembly.

[0046] The automobile electronic outside rearview mirror system provided by the application can realize image processing and display by using the electronic outside rearview mirror display assembly with the control and display functions, and does not need to additionally set a main controller to process the image, thereby reducing components. The automobile electronic rearview system provided by the embodiment only needs to connect the electronic outside rearview mirror display assembly with the outside rearview mirror image acquisition unit. Compared with the mode in the prior art that the main controller needs to be connected with the image acquisition unit and the display screen respectively, the automobile electronic outside rearview mirror system can reduce the wire harness, thereby reducing the wiring complexity.

[0047] The structure of the electronic outside rearview mirror display assembly included in the display device will be described below by taking one of the display devices as an example. Figure 3 The hardware structure schematic diagram of the automobile electronic outside rearview mirror system provided by the embodiment is shown in FIG. 1. The electronic outside rearview mirror display assembly included in the display device will be described below by taking one of the display devices as an example. Figure 3 The electronic outside rearview mirror display assembly may, for example, include a control unit 301, an image signal processing unit 302, a display control unit 303, an electronic outside rearview mirror display screen 304, and a deserializing unit 305.

[0048] The control unit 301 is connected with the image signal processing unit 302, the display control unit 303, the electronic outside rearview mirror display screen 304, and the deserializing unit 305 respectively. The deserializing unit 305 is connected with the outside rearview mirror image acquisition unit 311 and the image signal processing unit 302 respectively. The display control unit 303 is connected with the image signal processing unit 302 and the electronic outside rearview mirror display screen 304 respectively.

[0049] The image signal processing unit 302 is configured to perform image processing on the rearview field image, improve the quality of the rearview field image, and make the processed rearview field image more consistent with the actual scene. For example, linear correction, noise removal, bad point correction, white balance, and other correction operations on the rearview field image. The image signal processing unit 302 may, for example, be an image signal processing (ISP) chip or an ISP circuit.

[0050] The electronic exterior rearview mirror display assembly further comprises a deserializing unit 305. The deserializing unit 305 is connected with the exterior rearview mirror image collecting unit 311 and the image signal processing unit 302 respectively, and is used for converting the format of the rearview field image received from the exterior rearview mirror image collecting unit 311 into the format received by the image signal processing unit 302. For example, because the exterior rearview mirror image collecting unit 311 and the electronic exterior rearview mirror display assembly are two individuals, the signal of the exterior rearview mirror image collecting unit 311 needs to be output after the processing of the internal deserializing unit thereof, and is transmitted to the electronic exterior rearview mirror display assembly through the connected wire harness. The exterior rearview mirror image collecting unit 311 can output the rearview field image in a format conducive to ensuring the transmission quality of the rearview field image, and the format can be converted into a format matching the receiving format of the image signal processing unit 302 through the deserializing unit 305, so as to improve the transmission quality of the rearview field image.

[0051] The image signal processing unit 302 can send the processed rearview field image to the display control unit 303. The embodiment does not limit the transmission mode or communication protocol of the image signal processing unit 302 and the display control unit 303 for transmitting the processed rearview field image.

[0052] The display control unit 303 is used for driving the electronic exterior rearview mirror display screen 304 to display the processed rearview field image according to the processed rearview field image. For example, the display control unit 303 converts the received rearview field image into a signal recognizable by the screen, and transmits the signal to the electronic exterior rearview mirror display screen 304. The display control unit 303 can be a display control chip or a display control circuit, for example. The embodiment does not limit the transmission mode or communication protocol of the display control unit 303 and the electronic exterior rearview mirror display screen 304 for transmitting the processed rearview field image.

[0053] The electronic exterior rearview mirror display screen 304 is used for displaying the received rearview field image. The electronic exterior rearview mirror display screen 304 can be any type of display screen, such as a liquid crystal display screen, a touch display screen, etc.

[0054] When the electronic exterior rearview mirror display screen 304 only has a display function, it can comprise a display module to realize the display function. The display module can be a liquid crystal display module, for example.

[0055] When the electronic exterior rearview mirror display screen 304 has a touch function in addition to the display function, it can comprise a display module and a touch module. The touch module can be a module that detects the position of user touch by sensing the change of capacitance, for example. The electronic exterior rearview mirror display screen 304 with the touch module can send a control signal to the control unit 301 in a touch manner, so as to realize the control of the electronic exterior rearview mirror display assembly. For example, the brightness adjustment of the display screen.

[0056] The control unit 301 can configure parameters for the image signal processing unit 302, the display control unit 303, the electronic outside rearview mirror display screen 304, and the deserializing unit 305, and monitor the states.

[0057] Taking the image signal processing unit 302 as an example, the control unit 301 can transmit the signal of the parameter configuration to the image signal processing unit 302, so that the image signal processing unit 302 operates according to the configured parameters. Through the parameter configuration, the function of the image signal processing unit 302 in the electronic outside rearview mirror display assembly (i.e., what processing is performed on the received image), the signal path (i.e., from where the image is received, and to which unit the processed image is sent), and the state signal reported to the control unit 301 can be configured.

[0058] The state signal is used to represent whether the image signal processing unit 302 has a fault. The state signal can be reported to the control unit 301 when the state of the image signal processing unit 302 changes, so that the control unit 301 can timely learn the state of the image signal processing unit 302. It should be understood that the parameter configuration and state monitoring of other units can refer to the description of the image signal processing unit 302, and will not be repeated here.

[0059] In specific implementation, the control unit 301 can be any unit having a control function, for example, a microcontroller unit (MCU).

[0060] The electronic outside rearview mirror display assembly provided in the application is composed of the control unit 301, the image signal processing unit 302, the display control unit 303, the electronic outside rearview mirror display screen 304, and the deserializing unit 305, and the connection between the units realizes the image processing and display functions. Compared with the prior art, which needs two components, a main controller and a display screen, to realize the image processing and display functions, the number of components is reduced. Moreover, the electronic outside rearview mirror display assembly provided in the application only needs to be connected with the outside rearview mirror image acquisition unit 311, which can reduce the wire harness and thus reduce the wiring complexity, compared with the prior art, in which the main controller needs to be connected with the image acquisition unit and the display screen respectively.

[0061] Further, the electronic outside rearview mirror display assembly further includes a serial unit 308. The serial unit 308 is used for format conversion of the rearview image. The serial unit 308 is connected with the display control unit 303 and the domain controller 309 respectively. The automobile electronic outside rearview mirror display assembly and the domain controller 309 belong to two individual connections, and the connection between the automobile electronic outside rearview mirror display assembly and the domain controller 309 can be realized through the serial unit 308.

[0062] The serial unit 308 is connected with a domain controller 309 of the vehicle, and the domain controller 309 of the vehicle is connected with a vehicle display screen 310 of the vehicle. The domain controller 309 of the vehicle can control and manage various systems of the vehicle, and realize information interaction between in-vehicle systems. The vehicle display screen 310 can be any display screen installed inside the vehicle body and conveniently observed by the driver within the range of the driver's sight during driving, for example, can be a center display screen, or can be a co-pilot display screen, and is related to the display screen contained in the vehicle and its deployment.

[0063] In this implementation, the control unit 301 can control the display control unit 303 to transmit the processed rear view field image to the domain controller 309 through the serial unit 308. The present embodiment does not limit the manner in which the control unit 301 implements the above control operation, for example, the above control operation can be realized by parameter configuration, or by a separate control instruction. The control unit 301 can also perform parameter configuration and state monitoring on the serial unit 308.

[0064] Correspondingly, the domain controller 309 transmits the received processed rear view field image to the vehicle display screen 310 of the vehicle, to realize display of the rear view field image based on the vehicle display screen 310.

[0065] In this structure, the display of the rear view field image can be divided into the following two cases, for example:

[0066] The first case is that when the electronic exterior rearview mirror display screen 304 has a display fault, the rear view field image is displayed through the vehicle display screen 310.

[0067] The control unit 301 is connected with the electronic exterior rearview mirror display screen 304, and when the electronic exterior rearview mirror display screen 304 fails, its state signal is fed back to the control unit 301, so that the control unit 301 can monitor the failure of the electronic exterior rearview mirror display screen 304. When it is monitored that the electronic exterior rearview mirror display screen 304 has a display fault, the control unit 301 can send a control instruction to the control display control unit 303 to control the display control unit 303 to display the rear view field image to the vehicle display screen 310 through the serial unit 308 and the domain controller 309. In this way, the vehicle display screen 310 can be used as an alternative screen, so that when the electronic exterior rearview mirror display screen 304 fails, the rear view field image can be displayed through the vehicle display screen 310, thereby improving the fault tolerance of the automobile electronic exterior rearview mirror system and the driving safety.

[0068] The second: in response to the display instruction of the user, the rear view image is displayed through the vehicle display screen 310. If the electronic outside rearview mirror display screen 304 does not have a display failure, the rear view image will be displayed through the electronic outside rearview mirror display screen 304 and the vehicle display screen 310 at the same time, that is, the dual-channel display is realized, which is convenient for the driver to view the rear view image from various angles.

[0069] The display instruction of the user can be sent to the control unit 301 through the controller area network (CAN) bus 307 of the vehicle, for example. In this implementation, the electronic outside rearview mirror display assembly can further include a CAN unit 306 connected with the control unit 301 and the CAN bus 307 of the vehicle. After receiving the display instruction from the CAN bus 307, the CAN unit 306 analyzes the signal that can be recognized by the control unit 301. The CAN bus 307 is a serial communication bus used for communication between various elements in the vehicle.

[0070] The display instruction is used to trigger the control unit 301 to control the display control unit 303 to display the processed rear view image on the electronic outside rearview mirror display screen 304 at the same time as displaying the rear view image on the vehicle display screen 310 through the serial unit 308 and the domain controller 309, realizing dual-channel display. The display instruction can be set by the user through the user interface of the central control screen or through the central control function key. For example, after the CAN unit 306 receives the display instruction sent through the central control function key, the CAN unit 306 analyzes the signal received by the control unit 301 and transmits it to the control unit 301. The control unit 301 can control the display control unit 303 to transmit the processed rear view image to the domain controller 309 through the serial unit 308, and display it on the vehicle display screen 310 through the domain controller 309.

[0071] It should be understood that in the dual-channel display mode, when any one of the electronic outside rearview mirror display screen 304 and the vehicle display screen 310 fails, the other display screen can continue to display the rear view image, and there is no time difference in display failure. Further, when any one of the display screens fails, the other display screen can continue to provide the rear view image for the driver, improving the fault tolerance of the system and the safety of driving.

[0072] The method of the embodiment of the application will be described below through a specific example. Figure 4A structural schematic diagram of a display device of an automobile electronic outside rearview mirror system according to an embodiment of the present application is provided. In the present example, the control unit comprises an MCU 401 and its peripheral circuit; the image signal processing unit comprises an ISP chip 402 and its peripheral circuit; the display control unit comprises a display control chip 403 and its peripheral circuit; the electronic outside rearview mirror display screen 404 comprises a display module, a touch module and their peripheral circuit; the outside rearview mirror image acquisition unit comprises an outside rearview mirror image acquisition camera 411 and its peripheral circuit; the CAN unit comprises a CAN chip 406 and its peripheral circuit; the deserializing unit comprises a deserializing chip 405 and its peripheral circuit; and the serial unit comprises a serializer 408 and its peripheral circuit. Figure 4 The peripheral circuit of each unit is not shown in the figure.

[0073] The specific implementation of each unit of the automobile electronic outside rearview mirror system is as follows:

[0074] The outside rearview mirror image acquisition camera 411 acquires the rearview field image and transmits it to the deserializing chip 405 in accordance with the Gigabit Multimedia Serial Link 2 (GMSL2) standard. The deserializing chip 405 performs format conversion and outputs the rearview field image in accordance with the Mobile Industry Processor Interface Camera Serial Interface-2 (MIPI CSI-2) standard to the ISP chip 402. The ISP chip 402 performs image processing on the rearview field image and outputs it to the display control chip 403.

[0075] The converted rearview field image of the display control chip 403 can be displayed on the electronic outside rearview mirror display screen 404 or the vehicle-mounted display screen 410. The display mode depends on whether the MCU 401 monitors that the electronic outside rearview mirror display screen 404 is faulty or whether the MCU 401 monitors that a display instruction is received. The MCU 401 is connected to other units through the Inter Integrated Circuit (I2C).

[0076] If the MCU 401 monitors that the electronic outside rearview mirror display screen 404 is not faulty, the display control chip 403 is controlled to transmit the rearview field image to the electronic outside rearview mirror display screen 404 in accordance with the Low Voltage Differential Signaling (LVDS) standard, so as to realize display of the rearview field image on the electronic outside rearview mirror display screen 404.

[0077] If the MCU 401 monitors the electronic outside rearview mirror display screen 404 failure, or the MCU 401 receives the display instruction of the CAN signal from the CAN bus 407 of the vehicle analyzed by the CAN chip 406, the display control chip 403 transmits the rearview field image to the serializer 408 in the LVDS standard. Wherein, the CAN signal is in the form of voltage, represented by the potential difference on the CAN_H and CAN_L lines, CAN_H refers to the high bit data line of the CAN bus, and CAN_L refers to the low bit data line of the CAN bus. The CAN chip 406 is connected with the MCU 401 through the CAN transmission signal line (CAN Transport, CAN_TX) and the CAN reception signal line (CAN Receive, CAN_RX). The serializer 408 transmits the rearview field image to the domain controller 409 in the GMSL2 standard, and the rearview field image signal is transmitted to the vehicle display screen 410 through the domain controller 409, and the vehicle display screen 410 displays the rearview field image.

[0078] Optionally, the domain controller 409 can store the rearview field image, and use the stored rearview field image to realize the side blind area monitoring and early warning, the panoramic view field image, and other functions in combination with other components of the vehicle body, so as to realize the multiplexing of the outside rearview mirror image acquisition camera 411, and effectively reduce the design cost and the complexity of the vehicle assembly.

[0079] Compared with the existing system on chip (SOC) scheme, the ISP scheme used in the example has a lower hardware cost.

[0080] The automobile electronic outside rearview mirror system provided in the application can realize image processing and display by using the electronic outside rearview mirror display assembly with control and display functions, without the need of an additional main controller for image processing, so that the number of components can be reduced. The automobile electronic rearview system provided in the application only needs to connect the electronic outside rearview mirror display assembly with the outside rearview mirror image acquisition unit. Compared with the prior art in which the main controller needs to be connected with the image acquisition unit and the display screen respectively, the number of wire harnesses can be reduced, and the wiring complexity is reduced.

[0081] The application also provides a vehicle, which can include the automobile electronic outside rearview mirror system described in the above embodiments. The automobile electronic outside rearview mirror system of the vehicle includes a left outside rearview mirror image acquisition unit, a right outside rearview mirror image acquisition unit, a left electronic outside rearview mirror display assembly, and a right electronic outside rearview mirror display assembly.

[0082] The left outside rearview mirror image acquisition unit is disposed near the position where the conventional outside rearview mirror is installed on the left side of the vehicle body, and the left electronic outside rearview mirror display assembly is disposed in the vehicle and near the position where the left A pillar of the vehicle body is located or the position near the left front door of the vehicle. The right outside rearview mirror image acquisition unit is disposed near the position where the conventional outside rearview mirror is installed on the right side of the vehicle body, and the right electronic outside rearview mirror display assembly is disposed in the vehicle and near the position where the right A pillar of the vehicle body is located or the position near the right front door of the vehicle.
