[0056] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0057] The following describes the display method and device of the electronic rearview mirror, the vehicle, and the electronic device according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0058] Figure 1 A schematic flow chart of a display method for an electronic rearview mirror provided in an embodiment of the present disclosure.

[0059] like Figure 1 As shown, the method comprises the following steps:

[0060] Step 101, in response to a vehicle power-on signal, controlling the electrovariable area to display; the electrovariable area is determined by controlling the power-on area of ​​the electrovariable layer on the side windshield.

[0061] The embodiments of the present disclosure are applicable to any vehicle, and are not specifically limited by the embodiments of the present disclosure. It should be noted that in the embodiments of the present disclosure, after the vehicle is powered on, the electro-variable region will also be powered on, in order to prevent the display from failing when the user is driving the vehicle.

[0062] In the embodiment of the present disclosure, the position of the electrovariable area is controlled by controlling the energized area of ​​the electrovariable layer on the side windshield, wherein the energized area is the electrovariable area. The size of the electrovariable area can be changed by setting, for example: if the entire side windshield is set to be divided into 10 electrovariable areas, the entire side windshield ratio is used as the electrovariable area, or each electrovariable area is 1 / 10 the size of the side windshield; further, if the entire side windshield is set to be divided into 13 electrovariable areas, each electrovariable area is 1 / 13 the size of the side windshield. Specifically, the size of the electrovariable area can be preset according to actual application, and the embodiment of the present disclosure does not limit it. At the same time, after the size of the electrovariable area is set, it will not change if it is not manually updated.

[0063] At the same time, in order to clearly illustrate the embodiments of the present disclosure, Figure 2 As shown, Figure 2 This is a schematic diagram of the in-vehicle structure provided by the embodiment of the present disclosure. The side windshield of the vehicle is composed of an electrovariable layer and glass. The electrovariable layer serves as a display background for displaying the collected video. The electrovariable layer is transparent when not powered, just like ordinary glass. After power is supplied, the electrovariable area becomes milky white, and the electrovariable area in this state serves as a display background. By controlling the position of the powered area on the side windshield, the position of the electrovariable area on the side windshield can be flexibly controlled.

[0064] Step 102: Display the video captured by the camera outside the vehicle in a target display area, where the target display area is an area that overlaps with the electro-variable area.

[0065] In the disclosed embodiment, the target display area is an area that overlaps with the electrovariable area, wherein the electrovariable area serves as a display background and the target display area is used to display video images. The electrovariable area after power-on overlaps with the target display area and can be used as a display to display the video images captured by the camera outside the vehicle.

[0066] It should be noted here that when the vehicle is powered on and the monitoring target (vehicle driver) is captured, the vehicle will simultaneously output two feedback signals. One feedback signal is to define the electrovariant area by controlling the energized area of ​​the electrovariant layer; the other feedback signal is to display the video captured by the outside camera in the corresponding target display area through a high-speed video DP signal. After receiving the feedback signal from the vehicle, the vehicle drives the target display area at the corresponding position to display the video captured by the outside camera.

[0067] The display method of the electronic rearview mirror provided by the present disclosure controls the electrovariable area to display in response to the vehicle power-on signal; the electrovariable area is determined by controlling the power-on area of ​​the electrovariable layer on the side windshield, and the video collected by the external camera is displayed in the target display area, and the target display area is the area that coincides with the position of the electrovariable area. The embodiment of the present disclosure combines the target display area with the electrovariable area on the side windshield as the display area to display the video collected by the external camera, which can reduce the space occupied by the independent electronic rearview mirror screen in the vehicle and improve the flexibility of the space layout in the vehicle.

[0068] In one possible implementation of the disclosed embodiment, monitoring targets (vehicle drivers) of different heights need to match different display areas, i.e., electrovariable areas, because of their different sight lines, so that monitoring targets of different heights can more conveniently observe the screen. Therefore, controlling the electrovariable area for display can be implemented in, but not limited to, the following ways: determining the target height information of the head of the monitoring target on the driver's seat from the cabin ceiling; searching for the target energized area of ​​the electrovariable layer corresponding to the target height information according to the correspondence between the preset height information and the energized area, wherein the electrovariable layer includes at least two energized areas, each energized area corresponding to different height information; energizing the queried target energized area to obtain the electrovariable area.

[0069] In the disclosed embodiment, it can be understood that the corresponding electrovariable area is matched according to the target height information of the monitored target, that is, the position of the electrovariable area is adjusted according to the target height information of the head of the monitored target from the cabin ceiling. The preset height information and the correspondence between the energized area of ​​the electrovariable area are stored in the vehicle computer by means of data measurement and entry, that is, the preset function of the correspondence between the target height information of the monitored target and the energized area of ​​the electrovariable area is stored in the vehicle computer. The specific preset function of the correspondence is not limited by the disclosed embodiment. At the same time, the vehicle computer determines the position of the head of the monitored target through a mature image recognition algorithm, and determines the target height information of the monitored target through the relative position of the head and the cabin ceiling, thereby matching the corresponding electrovariable area.

[0070] In order to clearly illustrate the corresponding relationship between the target height information of the monitored target and the electro-variable region, the embodiment of the present disclosure provides Figure 3 To explain, Figure 3 As shown, the corresponding relationship between the height information of the monitored target and the electro-variable area can be Figure 3In the correspondence between the camera and H and V, the camera collects the image of the monitored target, and the vehicle computer determines the target height information of the monitored target through a mature image recognition algorithm, for example: H1, H2, H3. At this time, the vehicle computer matches the target height information of the monitored target to V1, V2, V3 corresponding to the electro-variable area through the preset function of the correspondence.

[0071] It should be noted that in the embodiments of the present disclosure, the position of the electrovariable area is adjusted by adjusting the position of the electrovariable area up and down, that is, adjusting the height position of the electrovariable area on the side windshield. At the same time, the basis for the up and down adjustment of the position of the electrovariable area is not limited to the target height information of the monitoring target, but can also be but not limited to: the height of the vehicle monitoring target, the height of the monitoring target's head relative to the driver's seat, etc. The specific basis for the up and down adjustment of the position of the electrovariable area is not limited by the embodiments of the present disclosure.

[0072] For the same monitoring target, after the height position of the electrovariable area on the side windshield is adjusted, the height position of the electrovariable area on the side windshield will not be adjusted again during use.

[0073] In actual applications, when the monitored target observes the display content of the target display area, the head and body of the monitored target will inevitably move. In order to make the monitored target have the best viewing angle, when the camera monitors that the monitored target moves its head and body position for a large distance in the car, the position of the target display area needs to be adjusted. Therefore, after the video captured by the external camera is displayed in the target display area, the following method can also be used but is not limited to: monitor the target moving distance of the monitored target on the driving seat through the in-vehicle camera; query the target display area corresponding to the target moving distance according to the mapping relationship between the preset moving distance and the energized area of ​​the electrovariable layer, and adjust the video captured by the external camera to the target display area for display.

[0074] In the embodiment of the present disclosure, the target display area is an area that overlaps with the electrovariable area. Therefore, the position adjustment of the target display area can be understood as the position adjustment of the electrovariable area. For the sake of convenience, the subsequent embodiments will explain the position adjustment of the electrovariable area.

[0075] It should be noted here that the position adjustment of the electrovariable area in the embodiment of the present disclosure is a horizontal adjustment, and the adjustment method is the horizontal adjustment of the position of the electrovariable area, that is, the front and rear position of the electrovariable area on the side windshield is adjusted. At the same time, the front and rear position of the electrovariable area on the side windshield is adjusted in real time, that is, according to the different ranges of the moving head and body position of the monitored target in the car monitored by the camera, the front and rear position of the electrovariable area on the side windshield is adjusted accordingly.

[0076] At the same time, related to the above-mentioned embodiment, the front and rear positions of the electrovariable area on the side windshield can also be adjusted in real time according to the target sight range of the monitored target. Therefore, the following method can also be adopted but not limited to: determine the target sight range of the monitored target on the driver's seat through the in-vehicle camera; query the target display area corresponding to the target sight range according to the mapping relationship between the preset sight range and the energized area of ​​the electrovariable layer, and adjust the video collected by the external camera to the target display area for display. By monitoring the target moving distance of the monitored target and determining the sight range of the monitored target, the front and rear positions of the electrovariable area on the side windshield can be adjusted in real time, so that the monitored target can always maintain the best viewing angle, thereby improving the vehicle use experience.

[0077] In one possible implementation of the disclosed embodiment, in order to better display a clear video image and allow the monitoring target to clearly see the video image, the video image is displayed in the target display area as an OLED display. Therefore, the video captured by the external camera is displayed in the target display area. It can be implemented in the following manner but not limited to: the video captured by the external camera is displayed in the OLED display area, wherein the target display area is the OLED display area. Among them, the OLED display area, i.e., the target display area, overlaps with the electro-variable area. The OLED display area (target display area) will be adjusted simultaneously with the adjustment of the electro-variable area, and always keep overlapping. The overlap of the OLED display area (target display area) and the electro-variable area can display a clearer video image.

[0078] In one implementable manner of the disclosed embodiment, when the vehicle is in a parking scenario (P gear state), the target display area on the side windshield will automatically adjust to a position close to the bottom of the window for display, so as to provide more window space for the monitored target. Therefore, after the video captured by the external camera is displayed in the target display area, the following method may also be used but is not limited to: in response to the vehicle's parking signal, the overlapping electrovariable area and the target display area are controlled to move down to the bottom position of the side windshield.

[0079] It should be noted here that while the target display area is automatically adjusted to a position near the bottom of the window for display, the on-board screen will become a display screen for the vehicle's surrounding status. When there are vehicles coming from behind or people passing through or obstacles, it will automatically remind the monitored target to pay attention to safety, bringing a more complete display of perception information, thereby further enhancing the user experience of the monitored target.

[0080] The present disclosure also provides a display method for an electronic rearview mirror, please refer to Figure 4 ,like Figure 4 As shown, including:

[0081] Step 401, in response to a vehicle power-on signal, controlling the electrovariable area to display; the electrovariable area is determined by controlling the power-on area of ​​the electrovariable layer on the side windshield.

[0082] For the description of step 401 , please refer to the relevant detailed description of the above embodiment, and the embodiment of the present disclosure will not be described one by one here.

[0083] Step 402, determining target height information of the head of the monitored target at the driver's seat from the cabin ceiling.

[0084] Step 403, searching for a target energized area of ​​the electrovariable layer corresponding to the target height information according to the correspondence between the preset height information and the energized area, wherein the electrovariable layer includes at least two energized areas, each energized area corresponding to different height information.

[0085] Step 404: energize the queried target energized area to obtain the electro-variable area.

[0086] Step 405: Display the video captured by the camera outside the vehicle in a target display area, where the target display area is an area that overlaps with the electro-variable area.

[0087] Step 406: display the video captured by the external camera in an OLED display area, wherein the target display area is the OLED display area.

[0088] Step 407: monitor the target moving distance of the monitoring target on the driving position through the in-vehicle camera.

[0089] Step 408, according to the mapping relationship between the preset moving distance and the energized area of ​​the electrovariable layer, query the target display area corresponding to the target moving distance, and adjust the video captured by the external camera to the target display area for display.

[0090] Step 409, determining the target sight range of the monitoring target on the driver's seat through the in-vehicle camera.

[0091] Step 410, according to the mapping relationship between the preset visual range and the energized area of ​​the electrovariable layer, query the target display area corresponding to the target visual range, and adjust the video captured by the external camera to the target display area for display.

[0092] In the embodiment of the present disclosure, specific instructions are provided for steps 402-410. At the same time, the embodiment of the present disclosure provides a schematic diagram of the structure of vehicle feedback and execution, such as Figure 5 As shown, after the monitored target enters the vehicle, the vehicle computer determines the target height information of the monitored target through the image of the monitored target captured by the camera, and calculates the electrovariable area according to the preset function of the corresponding relationship between the target height information of the monitored target and the electrovariable area, and outputs 2 feedback signals at the same time, one of which is to define the electrovariable area by controlling the energized area of ​​the electrovariable layer; the other feedback signal is to display the video image captured by the external camera in the corresponding target display area through the high-speed video DP signal. After receiving the feedback signal from the vehicle computer, the vehicle drives the target display area at the corresponding position to display the video image captured by the external camera. When the monitored target moves its head and body position over a large distance in the vehicle, the camera captures the movement, and the vehicle computer adjusts the position of the electrovariable area in time. At the same time, the camera can also capture the line of sight of the monitored target, and adjust the position of the electrovariable area according to the line of sight of the monitored target. During the whole process, the camera automatically captures the image, and the vehicle computer automatically adjusts the position of the electrovariable area, so that the monitored target does not need to operate. It should be noted here that Figure 5 The vehicle-mounted host in the vehicle is the vehicle computer.

[0093] The side windshield defines the target display area by adjusting the electrovariable area, and displays the OLED display area of ​​the plane at the same time. The monitored target can see the display content of the target display area plane. The overlapping display of the OLED display area and the electrovariable area can display a clear picture, allowing the monitored target to clearly see the video picture.

[0094] Step 411, in response to a parking signal of the vehicle, controlling the overlapped electrovariable area and the target display area to move downward to the bottom position of the side windshield.

[0095] For the description of step 411 , please refer to the relevant detailed description of the above embodiment, and the embodiment of the present disclosure will not be described one by one here.

[0096] In summary, the embodiments of the present disclosure can achieve the following effects:

[0097] 1. By combining the target display area with the electro-variable area on the side windshield, the space occupied by the independent electronic rearview mirror screen in the car can be reduced, thereby improving the flexibility of the interior space layout.

[0098] 2. The target height information of the monitored target is determined by a mature image recognition algorithm, and the corresponding electro-variable area is matched according to a preset function of the correspondence between the preset height information and the energized area. The matching of the electro-variable area range can be automatically completed, thereby eliminating the need for monitoring the target to operate.

[0099] 3. The camera automatically captures the images of the target's head and body moving a long distance in the car, as well as the target's field of vision, and adjusts the position of the electro-variable area to adapt to the best viewing angle of the target in real time, thereby improving the user experience of the target.
