The present application is to be implemented or applied in other different embodiments, and the details of the present application can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, and are not intended to limit the scope of protection of the present application.

[0025] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present application, and only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The shapes, number and proportions of the components in actual implementation can be arbitrarily changed, and the layout pattern of the components can be more complex.

[0026] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application, however, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details, and in other embodiments, the known structures and devices are shown in the form of block diagrams rather than in the form of details, to avoid making the embodiments of the present application difficult to understand.

[0027] Figure 1 A rearview mirror adjusting system shown in an exemplary embodiment of the present application includes an operation and display module, a control module, an active adjusting demand module, a rearview mirror body, a seat sensor and a camera.

[0028] In an embodiment of the present application, during driving of a vehicle by a user, a center of gravity position of a main driver is generated based on a seat sensor of the main driver. When the seat sensor detects a person, the output center of gravity position of the main driver should be continuously and linearly obtained, and can be adjusted according to the posture of the person and updated in real time. Based on a camera in the vehicle, the positions of two eyes of the main driver are recognized, and the middle position is taken to generate an eye center position. In the embodiment, the camera mainly focuses on the object in the height when collecting the eye center position, and the height accuracy of the eye center position is preferentially ensured.

[0029] In an embodiment of the present application, the control module acquires the center of gravity position and the eye center position of the driver, and generates a target spatial coordinate point based on the center of gravity position and the eye center position of the driver, obtains a target angle of the rearview mirror in a preset coordinate-angle table built in the control module based on the target spatial coordinate point, and generates a rearview mirror control instruction according to the target angle of the rearview mirror to control the rearview mirror body to intelligently adjust.

[0030] In an embodiment of the present application, in the intelligent adjustment process of the rearview mirror, the active adjustment demand of the user has the highest priority, and no matter what the target angle of the rearview mirror is, when the user manually adjusts the angle of the rearview mirror, the rearview mirror body is adjusted according to the user adjustment instruction.

[0031] In an embodiment of the present application, the control module further acquires the current vehicle speed, and when it is judged that the current vehicle speed is greater than a preset speed threshold, for example, when the vehicle speed is greater than 120 km / h, the rearview mirror no longer automatically adjusts, and the user is informed by the operation and display module that the automatic adjustment is exited due to overspeed. At this time, the control module only responds to the active adjustment demand of the user. The 120 km / h in this embodiment is only an illustrative embodiment of the present application, and the preset speed threshold can also be other values. The 120 km / h does not limit the scope of the present application.

[0032] In an embodiment of the present application, the operation and display module is used for the user to turn on and off the automatic adjustment function of the rearview mirror. When the rearview mirror is adjusted, the operation and display module pushes a message suggesting the user to turn on the automatic adjustment of the rearview mirror, acquires a user instruction, the user instruction is used to represent the permission state of the user to the message, if the permission state is permission, the user allows to turn on the automatic adjustment of the rearview mirror, and the rearview mirror is adjusted based on the target angle of the rearview mirror.

[0033] In an embodiment of the present application, the operation and display module is used to limit the use scene of the automatic adjustment function of the rearview mirror. When the vehicle is in a non-P gear, the automatic adjustment function of the rearview mirror is turned off and cannot be turned on. The operation and display module can also display a text function explanation and an overspeed pop-up window to the user.

[0034] In an embodiment of the present application, the active adjustment demand module is a rearview mirror control demand that can be realized by the user actively operating, including all passive adjustment paths on the vehicle, such as physical / virtual buttons, voice control, etc.

[0035] In an embodiment of the present application, the rearview mirror body is used to respond to the adjustment demand of the control module in various directions.

[0036] Please refer to Figure 2 , Figure 2is a rearview mirror adjustment method flowchart shown by an example embodiment of the present application, in an example embodiment, the rearview mirror adjustment method comprises at least steps S210 to S230, which are described in detail as follows:

[0037] Step S210, obtain the driver's center of gravity position and the eye center position.

[0038] In an embodiment of the present application, the driver's center of gravity position is collected by a seat sensor of the driver's seat on the vehicle. When the seat sensor detects a person, the output driver's center of gravity position is continuous and linear. The seat sensor on the seat can update the driver's center of gravity position in real time according to the user's posture adjustment.

[0039] In an embodiment of the present application, the eye position of the user is recognized by an image collection device on the vehicle, such as an in-vehicle camera, and the eye center position is obtained by taking the middle position. In actual collection, the main concern is the reference object in height, and the height accuracy of the eye center position is the priority.

[0040] Step S220, generate a target space coordinate point based on the driver's center of gravity position and the eye center position.

[0041] In an embodiment of the present application, the X-axis and Y-axis of the three-dimensional coordinate system are generated based on the vehicle body chassis plane; the Z-axis of the three-dimensional coordinate system is generated according to the rearview mirror position midpoint; the projection point of the rearview mirror on the X-axis and Y-axis is taken as the origin of the three-dimensional coordinate system; and the target space coordinate point is generated based on the three-dimensional coordinate system, the driver's center position and the eye center position.

[0042] In an embodiment of the present application, a target space coordinate point is generated based on the collected driver's center of gravity position and eye center position.

[0043] Step S230, obtain the rearview mirror target angle according to the target space coordinate point and the preset coordinate-angle table, and adjust the rearview mirror.

[0044] In an embodiment of the present application, the corresponding rearview mirror target angle is found in the preset coordinate-angle table based on the target space coordinate point, and the rearview mirror is adjusted based on the rearview mirror target angle. The preset coordinate-angle table is a mapping relationship between the target space coordinate point and the rearview mirror target angle, which is preset in advance based on the user's personal habits and the vehicle type.

[0045] In an embodiment of the present application, if the target space coordinate point is in the first coordinate interval, the target angle of the rearview mirror is the first angle; if the target space coordinate point is in the second coordinate interval, the target angle of the rearview mirror is the second angle; if the target space coordinate point is in the third coordinate interval, the target angle of the rearview mirror is the third angle; if the target space coordinate point is in the fourth coordinate interval, the target angle of the rearview mirror is the fourth angle; if the target space coordinate point is in the fifth coordinate interval, the target angle of the rearview mirror is the fifth angle. In this embodiment, each coordinate interval and the corresponding angle are set based on experience by those skilled in the art, and the user can also customize the coordinate interval and the angle.

[0046] In an embodiment of the present application, considering that different users have different needs for the line-of-sight angle of the rearview mirror, the preset coordinate-angle table is updated and modified by the rearview mirror correction angle and the rearview mirror update angle in the preset coordinate-angle table, so that it is more suitable for the user's rearview mirror use habit.

[0047] In an embodiment of the present application, after step S230, if a rearview mirror angle adjustment instruction is received, a rearview mirror correction angle is obtained according to the rearview mirror angle adjustment instruction and the current rearview mirror angle, and the rearview mirror is adjusted based on the rearview mirror correction angle; a rearview mirror update angle is obtained based on the rearview mirror correction angle and the target angle of the rearview mirror; and the rearview mirror update angle replaces the target angle of the rearview mirror in the preset coordinate-angle library to update the preset coordinate-angle table.

[0048] In an embodiment of the present application, a message suggesting that the user turn on the automatic adjustment of the rearview mirror is pushed; a user instruction is obtained, which is used to represent the permission state of the user to the message; if the permission state is permission, the user allows to turn on the automatic adjustment of the rearview mirror, and the rearview mirror is adjusted based on the target angle of the rearview mirror; if the permission state is not permission, the user does not allow to turn on the automatic adjustment of the rearview mirror, and the adjustment of the rearview mirror is stopped.

[0049] In an embodiment of the present application, if the user actively controls the rearview mirror to adjust, the priority of the user is the highest, at which time the automatic adjustment of the rearview mirror is paused, and the angle adjusted by the user is used as the reference. The user can also set the opening and closing of the automatic adjustment function of the rearview mirror.

[0050] In an embodiment of the present application, for safety considerations, the automatic adjustment function of the rearview mirror can only be turned off but not turned on when it is not in the P gear; the user can also be provided with a textual function description and a display of an overspeed pop-up window.

[0051] In an embodiment of the present application, after S230, the target angle of the rearview mirror is stored, and the next time the vehicle is powered on, the rearview mirror is automatically adjusted to the target angle of the rearview mirror.

[0052] In an embodiment of the present application, before S230, the current vehicle speed is detected, and if the current vehicle speed is greater than a preset vehicle speed threshold, the adjustment of the rearview mirror is prohibited.

[0053] In an embodiment of the present application, the current vehicle speed is detected, and if the current vehicle speed is greater than 120 km / h, the rearview mirror no longer performs automatic adjustment, and the user is notified through the vehicle screen that "speeding has been detected, and the automatic adjustment of the rearview mirror has been exited", at this time, the rearview mirror only responds to the active adjustment of the user.

[0054] Please refer to Figure 3 , Figure 3 is a rearview mirror adjustment flowchart shown by another exemplary embodiment of the present application, which at least includes steps S301 to S309, which are described in detail as follows:

[0055] Step S301, personnel data is collected and updated in time, and the personnel data includes the center of gravity position and the eye center position of the main driver.

[0056] Step S302, spatial data is generated and converted into control instructions, and the target spatial coordinate point is generated based on the center of gravity position and the eye center position of the main driver. The target angle of the rearview mirror is obtained according to the target spatial coordinate point and the preset coordinate-angle table, and if there is a correction angle of the rearview mirror, the update angle of the rearview mirror is obtained based on the correction angle of the rearview mirror and the target angle of the rearview mirror, the update angle of the rearview mirror is taken as the new target angle of the rearview mirror, and the control instructions are generated according to the target angle of the rearview mirror to control the automatic adjustment of the rearview mirror.

[0057] Step S303, whether the user turns on the function switch of the automatic adjustment of the rearview mirror is detected, if yes, it jumps to step S306, and if no, it jumps to step S304.

[0058] Step S304, if the user does not turn on the function switch of the automatic adjustment of the rearview mirror, the active adjustment of the user is performed, the user angle of the rearview mirror is obtained based on the input source of the user such as key, virtual case or sound, and the rearview mirror is adjusted.

[0059] In step S305, the rearview mirror user angle determines the user's adjustment requirements, converts these requirements, and continuously optimizes the rearview mirror correction angle. If the user has not enabled the rearview mirror automatic adjustment function, the user-operated rearview mirror user angle is compared with the rearview mirror target angle to form a rearview mirror correction angle. The rearview mirror correction angle is continuously updated based on the user's operation. The rearview mirror update angle is obtained based on the latest rearview mirror correction angle and the rearview mirror target angle. When the user selects to enable the rearview mirror automatic adjustment function, the rearview mirror target angle is replaced with the rearview mirror update angle, and the rearview mirror is adjusted based on the updated rearview mirror target angle. The updated rearview mirror target angle is stored in the vehicle upon power-off and updated to the preset coordinate-angle table, which is then recalled upon power-on.

[0060] Step S306: If the user has turned on the rearview mirror function, the rearview mirror is automatically adjusted continuously and proactively with a certain periodicity based on the rearview mirror target angle.

[0061] Step S307 determines whether the user has made any active adjustments to the rearview mirror. If the user has not, the process returns to step S301, where user data is continuously collected and the driver's center of gravity and eye center positions are updated in real time. New target space coordinates and a target rearview mirror angle are generated to continuously and periodically control the rearview mirror angle. If the user has made any active adjustments to the rearview mirror, the process proceeds to step S308.

[0062] Step S308: If the user actively adjusts the rearview mirror to obtain a rearview mirror user angle, the rearview mirror is adjusted based on the rearview mirror user angle.

[0063] Step S309, memorizes and maintains the user angle of the rearview mirror adjusted by the user, converts it into a rearview mirror correction angle based on the position adjusted by the user, and jumps to step S305. If the rearview mirror target angle obtained in step S302 does not differ from the rearview mirror user angle by more than the preset range, the current rearview mirror angle continues to be maintained.

[0064] See Figure 4 , Figure 4 This is a schematic diagram of a three-dimensional coordinate system shown in an exemplary embodiment of the present application, combined with Figure 4 In one embodiment of the present application, the target space coordinate point is generated as follows.

[0065] In one embodiment of the present application, the vehicle model data is combined with the vehicle chassis plane to generate the X-axis ( Figure 4 X) and Y axis ( Figure 4 In this embodiment, the Z axis is generated by the position of the midpoint of the left rearview mirror ( Figure 4 Z), the projection point of the left rearview mirror on the X-axis and Y-axis is used as the coordinate origin ( Figure 4The coordinate system is generated.

[0066] In an embodiment of the present application, the center of gravity of the driver is determined according to the seat sensor output (S1), Figure 4 In the embodiment a), the coordinates of the X-axis and the Y-axis are determined, and in the embodiment b), the height of the Z-axis is determined according to the eye center position output by the camera (S2), Figure 4 In the embodiment a), the coordinates of the X-axis and the Y-axis are determined, and in the embodiment b), the height of the Z-axis is determined according to the eye center position output by the camera (S2), Figure 5 In the embodiment a), the coordinates of the X-axis and the Y-axis are determined, and in the embodiment b), the height of the Z-axis is determined according to the eye center position output by the camera (S2),

[0067] In an embodiment of the present application, based on the target space coordinate point and based on the preset coordinate-angle table, the target angle of the rearview mirror is obtained without the rearview mirror correction angle, and the rearview mirror is automatically controlled to the target angle of the rearview mirror.

[0068] In an embodiment of the present application, if the user actively adjusts the rearview mirror based on the target angle of the rearview mirror controlled automatically, a rearview mirror correction angle is obtained, based on which a false correction space coordinate point range is obtained, and the target space coordinate point and the correction space coordinate point are subtracted in three-dimensional data to obtain an updated space coordinate point. In subsequent adjustment, the real-time target space coordinate point and the memorized correction space coordinate point are superimposed in three-dimensional data, and based on the preset coordinate-angle table, the final target position of the optimized rearview mirror is obtained.

[0069] In an embodiment of the present application, considering that the target space coordinate point will change multiple times and greatly in a short time when the user adjusts the sitting posture, the control module further includes a filtering process for the target space coordinate point. That is, the target space coordinate point value is within a certain three-dimensional range within a certain time (such as 200 ms), which is recognized as a valid value. At this time, the automatic adjustment of the rearview mirror is temporarily not responsive from the perspective of field of view safety, but can respond to the active adjustment of the user.

[0070] In an embodiment of the present application, a three-dimensional coordinate system is generated based on the information of the vehicle, so that the generated target space coordinate point is more accurate.

[0071] In an embodiment of the present application, the rearview mirror correction angle is obtained based on the angle adjusted by the user, and the rearview mirror is adjusted based on the rearview mirror correction angle, so that the automatic adjustment of the rearview mirror is more in line with the personal habits of the user.

[0072] In an embodiment of the present application, the user is asked for permission before the automatic adjustment of the rearview mirror, so that the angle of the rearview mirror can be adjusted according to the will of the user.

[0073] In the embodiment of the present application, the rearview mirror is prohibited from being adjusted when the vehicle speed is greater than the preset threshold, so that the rearview mirror is automatically adjusted at a safe speed to prevent accidents.

[0074] In the embodiment of the present application, the target angle of the rearview mirror is obtained according to a plurality of coordinate intervals, and the appropriate target angle of the rearview mirror can be accurately obtained based on the target space point.

[0075] In the embodiment of the present application, the current rearview mirror angle is stored before power-off, so that the rearview mirror can be quickly adjusted to a reasonable angle when powered on next time, and the subsequent automatic adjustment of the rearview mirror is facilitated.
