Description

Technical Field

[0001] The present invention relates to an electronic rearview mirror, and in particular to an electronic rearview mirror adjustment interaction system, an electronic rearview mirror and a car. Background Art

[0002] The field of view provided by traditional rearview mirrors varies with the driver's eye point. For example, if the mirror's position relative to the ground remains unchanged, the lower the driver's eye point is, the higher the indirect field of view through the rearview mirror, and vice versa. However, electronic rearview mirrors do not change with the driver's eye point. However, the default field of view required by regulations may not necessarily be what all drivers want to see in all driving conditions. For example, some drivers prefer to see more of the sky or more of the car body.

[0003] At this point, the driver may face a dilemma. Because adjusting the default field of view for an electronic rearview mirror isn't as intuitive and easy to understand as adjusting a traditional rearview mirror, drivers often become confused during the adjustment process, losing track of the relative relationship between the current adjusted field of view and the default regulatory field of view. While regulations allow for icons to be overlaid on the electronic rearview mirror's display to help the driver understand the mirror's operating status, most icons fail to clearly and intuitively help the driver understand the relative relationship between the current field of view and the default field of view. Summary of the Invention

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0052] The Class IV and Class II fields of view described in this article refer to the Class IV and Class II fields of view described in the Chinese national standard GB15084 or the European standard ECE-R46.

[0053] Example 1:

[0054] like Figure 1-11 As shown, this embodiment provides an electronic rearview mirror adjustment interactive system, including:

[0055] A field of view acquisition module 11, wherein the field of view acquisition module 11 is used to acquire a current field of view image of the electronic rearview mirror;

[0056] The field of view adjustment module 12 is used to adjust the current field of view acquisition range of the electronic rearview mirror;

[0057] The schematic generation module 15 is used to generate a corresponding default field of view schematic and a current field of view schematic based on the current field of view acquisition range and the default field of view acquisition range, and superimpose the default field of view schematic and the current field of view schematic to generate a corresponding field of view deviation schematic, and superimpose it on the current field of view image to produce a corresponding rearview mirror display image.

[0058] In this embodiment, by superimposing the schematic diagrams of the default field of view and the current field of view on the field of view image output by the system, the user is helped to understand the current field of view in a timely manner.

[0059] More specifically, when the driver is driving a large or medium-sized vehicle such as a truck, in situations such as turning, the driver needs to adjust the field of view of the electronic rearview mirror. In this case, the driver adjusts the current field of view of the electronic rearview mirror through an adjustment device such as a button set on the driver's seat. Generally, the adjustment is made to the left or right. When the system receives the adjustment signal, it calculates whether the field of view of the adjusted electronic rearview mirror is consistent with the default field of view. If not, a corresponding field of view deviation indication is generated and superimposed on the original current field of view image and displayed on the electronic rearview mirror, generally set in the upper right corner of the electronic rearview mirror.

[0060] Preferably, the schematic generation module 15 specifically includes: a default field of view schematic generation module, used to generate the default field of view schematic; a current field of view schematic generation module, used to generate the current field of view schematic; a deviation calculation module, used to set the relative position of the current field of view schematic and the default field of view according to the degree of deviation between the current field of view acquisition range and the default field of view acquisition range.

[0061] Generally speaking, the default field of view is stored in the ECU of the car, more specifically, it is set in the flash, and part of the pixels captured by the camera 30 are selectively displayed through the range of the default field of view. The default field of view range 13 can be simply regarded as an immovable square box in the pixel matrix captured by the camera 30, and its position is displayed on the display 40 after abstract processing, so as to inform the user of the range of the default field of view; the current field of view can be regarded as a movable square box, which moves on the pixel matrix according to the user's operation, displays the pixels of its selected range on the display 40, and displays its position after abstract processing by the conversion function on the display 40, and its specific position is obtained by the deviation between the default field of view range 13 and the user adjustment input. At the specific schematic display level, the deviation between the default field of view range 13 and the user adjustment input is mapped to the display 40 after being processed by the conversion function for display.

[0062] Further preferably, when the current field of view 14 is to the left of the default field of view 13, the current field of view is schematically shown to the left relative to the default field of view; when the current field of view 14 is to the right of the default field of view 13, the current field of view is schematically shown to the right relative to the default field of view; when the current field of view 14 is above the default field of view 13, the current field of view is schematically shown to the above the default field of view; when the current field of view 14 is below the default field of view 13, the current field of view is schematically shown to the below the default field of view.

[0063] At the specific schematic display level, the default field of view range 13 is first displayed, and then input and output are performed according to the deviation input by the user. If the content input by the user causes the collection frame of the current field of view to deviate from the default field of view, the corresponding schematic is displayed according to the direction of the deviation input by the user.

[0064] Specifically, when the user inputs a corresponding operation in the X-axis direction or the Y-axis direction, the current field of view 14 moves in the X-direction and the Y-direction relative to the default field of view 13 according to the operation, and then the corresponding movement is indicated, thereby displaying the corresponding indication movement.

[0065] Further preferably, when there is a deviation between the current field of view 14 and the default field of view 13, the current field of view indicator is set to a preset current deviation field of view color, the default field of view indicator is set to a default deviation field of view color, and the current field of view indicator is superimposed on the default field of view indicator; the default deviation field of view color is orange; and the current deviation field of view color is red. When the current field of view 14 and the default field of view 13 are consistent, the field of view deviation indicator is displayed in a preset default field of view color; the default field of view color is green. The default field of view indicator is set to a rectangular frame; and the current field of view indicator is set to a rectangular frame.

[0066] In terms of specific display methods, when no deviation occurs, the default field of view 13 is displayed, and the field of view range diagram is displayed in green. When a deviation occurs, the default field of view diagram and the current field of view diagram are highlighted to indicate a warning, wherein the default field of view diagram is displayed in orange and the current field of view diagram is displayed in red, and the current field of view diagram is set on the upper layer of the default field of view diagram.

[0067] Further preferably, the current field of view image is a Class II field of view image. The schematic generating module 15 further includes a Class IV field of view schematic generating module 15 for generating a Class IV field of view acquisition range schematic, the Class IV field of view acquisition range schematic being located below or above the current field of view schematic.

[0068] During actual use, the display 40 typically displays the Class II field of view image on the top and the Class IV field of view on the bottom. This can be adjusted up or down as needed, depending on the layout of the Class II and Class IV fields of view of the electronic rearview mirror. However, generally, only the Class II field of view image is adjusted. Therefore, to more intuitively display the deviation in field of view, the icon is configured to resemble the shape of the display 40 itself. Thus, a corresponding Class IV field of view acquisition range icon is provided below the current field of view icon, thereby more intuitively informing the driver of the current field of view.

[0069] Example 2:

[0070] like Figure 1-11As shown, this embodiment provides an electronic rearview mirror, including an ECU unit 10, a display 40, a camera 30, and an adjustment interaction device 20. The ECU unit 10 runs an electronic rearview mirror adjustment interaction system described in Example 1; the adjustment interaction device 20 is used to receive external field of view adjustment interaction and generate a corresponding adjustment signal to adjust the current field of view acquisition range of the camera 30; the camera 30 is used to collect the current field of view image of the current field of view acquisition range; the electronic rearview mirror adjustment interaction system is used to generate the corresponding rearview mirror display image according to the current field of view image and the default field of view acquisition range preset in the ECU unit 10 and the current field of view acquisition range, and display it on the display 40.

[0071] In this embodiment, when the driver is driving a large or medium-sized vehicle such as a truck, in situations such as turning, the driver operates the adjustment interaction device 20 to input the desired deviation. The ECU unit 10 calculates the corresponding current field of view 14 based on the default field of view 13 stored in its flash and the deviation input by the driver. Then, the ECU unit 10 selectively displays part of the pixels captured by the camera 30 as the current field of view image through the current field of view 14, and superimposes the default field of view diagram and the current field of view diagram on the current field of view image after corresponding range mapping processing.

[0072] Specifically, when the user inputs a corresponding operation in the X-axis direction or the Y-axis direction, the current field of view 14 moves in the X-direction and the Y-direction relative to the default field of view 13 according to the operation, and then the corresponding movement is indicated, thereby displaying the corresponding indication movement.

[0073] In terms of specific display methods, when no deviation occurs, the default field of view 13 is displayed, and the field of view range diagram is displayed in green. When a deviation occurs, the default field of view diagram and the current field of view diagram are highlighted to indicate a warning, wherein the default field of view diagram is displayed in orange and the current field of view diagram is displayed in red, and the current field of view diagram is set on the upper layer of the default field of view diagram.

[0074] Example 3:

[0075] Example 3 provides a car, which is equipped with an electronic rearview mirror as described in Example 2, and the adjustment interaction device 20 is arranged on the main driving side of the car.

[0076] Generally, the interactive device is located on the main driver's side of the vehicle, using buttons for easy user operation. When a driver is operating a large or medium-sized vehicle, such as a truck, and in situations such as turning, they adjust the interactive device 20 to input a desired deviation. The ECU 10 then calculates the corresponding current field of view 14 based on the default field of view 13 stored in its flash memory and the deviation input by the driver. The ECU then selectively displays a portion of the pixels captured by the camera 30 as the current field of view image based on the current field of view 14. The default field of view and the current field of view are then mapped and superimposed on the current field of view image for display.

[0077] Through the above embodiments, the present invention generates a corresponding field of view deviation diagram by comparing the current field of view acquisition range and the default field of view acquisition range, thereby clearly helping the driver understand the relative relationship between the current field of view position and the default field of view position, thereby improving overall safety.

[0078] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0079] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
