[0040] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of Specific Embodiments

[0041] Here, specific embodiments will be described in detail, and examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following specific examples do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0042] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented, for example, in an order different from those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, products, or devices.

[0043] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or fully authorized by all parties, and the collection, use, and processing of relevant data need to comply with relevant laws, regulations, and standards, and corresponding operation entrances are provided for users to choose to authorize or refuse.

[0044] Exemplarily, Figure 1 It is a comparison schematic diagram of a conventional external rearview mirror and a narrow-bezel external rearview mirror. As Figure 1 shown in (a) of, the periphery of the lens of the conventional external rearview mirror surrounds a plastic housing, and space is reserved for the lens to rotate; as Figure 1As shown in (b), the narrow-frame rearview mirror lens is integrated with the plastic housing. Currently, vehicle exterior rearview mirrors generally feature impact-absorbing mechanisms to protect both occupants and the mirror itself. This mechanism relies on an elastic locking mechanism between the motor and the mirror housing. The mirror housing can be disengaged from the motor and rotated in the Y direction to cushion any impact. Figure 2 The figure is a schematic diagram of the position of the rearview mirror housing after being hit. Figure 2 (a) in Figure 2 (b) and Figure 2 As shown in (c), the rearview mirror housing changes its position at different angles after being hit by external force.

[0045] In related technologies, functional logic is typically determined by obtaining variables such as the operating current and position voltage output by the motor to achieve adjustment of the exterior rearview mirror. However, when the exterior rearview mirror is impacted or manually twisted, the mirror housing and the exterior rearview mirror motor become unlocked. Even after the mirror housing is unlocked, the motor module continues to output variables such as the operating current and position voltage, causing the control module to misjudge that the mirror is still in the normal locked state. This creates a "blind spot" that the control module cannot perceive. Consequently, when the control module receives adjustment instructions for the exterior rearview mirror, due to the misjudgment that the mirror is still in the normal locked state, the control instructions it issues cannot be effectively executed, resulting in the failure of the adjustment function. Furthermore, this abnormal state cannot usually be automatically restored and requires manual intervention and mechanical reset to re-establish the locking relationship between the mirror housing and the motor, seriously affecting user experience and driving safety.

[0046] In order to solve the above problems, an embodiment of the present application provides a vehicle's exterior rearview mirror adjustment solution. By identifying variables such as operating current and position voltage and introducing drive time monitoring, the position change of the rearview mirror housing within the set adjustment time is monitored and compared with the position change threshold to determine whether the rearview mirror housing and the motor are unlocked; when it is determined that the rearview mirror housing and the motor are unlocked, an indication information is reported to the on-board host, triggering the automatic reset mechanism of the exterior rearview mirror, and executing the adjustment instruction to adjust the position of the exterior rearview mirror after the reset is completed, thereby effectively reducing the problem of the rearview mirror being unable to be adjusted due to the rearview mirror housing and the exterior rearview mirror motor being unlocked; in addition, through intelligent status monitoring, fault diagnosis and automatic reset mechanism, the vehicle can automatically reset the exterior rearview mirror under extreme working conditions, greatly improving the intelligence level and safety performance of the entire vehicle, and reducing the possibility of users driving without exterior rearview mirrors, which is of positive significance for improving the user's car experience and driving safety.

[0047] The following uses specific embodiments to elaborate in detail on the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0048] Figure 3 FIG. 1 is a schematic flow chart of an external rearview mirror adjustment method for a vehicle provided by an exemplary embodiment of the present application. The external rearview mirror adjustment method for a vehicle provided by an embodiment of the present application is applied to a control module in an external rearview mirror reset system of a vehicle. As Figure 3 shown, the external rearview mirror adjustment method for the vehicle includes the following steps:

[0049] S301. In response to an adjustment instruction for the external rearview mirror, adjust the position of the external rearview mirror, and obtain the position change amount of the rearview mirror housing within a set adjustment duration.

[0050] Exemplarily, when the control module receives the adjustment instruction, it drives the motor to adjust the position of the external rearview mirror, synchronously starts the timer to start timing, starts the position acquisition component to sample the position information of the rearview mirror housing, and stores the motor operating current, position voltage, and actual position of the rearview mirror housing in real time, so as to obtain the position change amount of the rearview mirror housing within a set adjustment duration, such as 200 ms. Among them, the adjustment instruction includes, but is not limited to, a position memory call instruction, a reverse tilt trigger instruction, or a manual adjustment request instruction, etc.; the position acquisition component is specifically used to monitor the position or displacement of the rearview mirror housing in the Y-axis direction, and the position acquisition component may include, but is not limited to, a Hall effect sensor, an optical encoder, or a strain gauge force sensor, etc.

[0051] S302. When the position change amount is less than or equal to the position change amount threshold, stop adjusting the position of the external rearview mirror, and report indication information to the vehicle's in-vehicle host. The indication information is used to characterize that the rearview mirror housing is disengaged from the lock of the external rearview mirror motor, and the in-vehicle host is used to issue a reset instruction for the external rearview mirror according to the indication information.

[0052] Exemplarily, assume that the position change amount threshold is, for example, 1°, 2°, or 3°; correspondingly, when the position change amount Δθ1 is greater than 2°, continue to adjust the position of the external rearview mirror until the adjustment is in place and then cut off the power supply of the motor; when the position change amount Δθ1 is less than or equal to 2°, immediately stop adjusting the position of the external rearview mirror, and report indication information to the vehicle's in-vehicle host through the Controller Area Network (CAN) bus. The indication information is, for example, the status code "0xE1", and this status code is used to characterize that the rearview mirror housing is disengaged from the lock of the external rearview mirror motor, and the in-vehicle host is used to issue a reset instruction for the external rearview mirror according to the indication information.

[0053] S303. Respond to the received reset instruction and reset the outside rearview mirror.

[0054] Correspondingly, when the control module receives the reset instruction, it resets the outside rearview mirror according to the set reset logic.

[0055] S304. After detecting that the outside rearview mirror is reset, execute the adjustment instruction to adjust the position of the outside rearview mirror.

[0056] Exemplarily, continuously monitor the position change of the outside rearview mirror. When it is detected that the reset of the outside rearview mirror is completed, load the adjustment instruction again to drive the motor to adjust the position of the outside rearview mirror, such as automatic folding, position memory, or tilting down when reversing, etc.

[0057] It should be noted that the above-set adjustment duration, such as 200 ms, the position change amount threshold, such as 1°, 2°, or 3°, and the status code "0xE1" are only examples. In actual applications, they can be set according to specific requirements and are not limited here.

[0058] The method for adjusting the outside rearview mirror of a vehicle provided by the embodiment of the present application can accurately determine whether the rearview mirror housing is disengaged from the lock of the outside rearview mirror motor by obtaining the position change amount of the rearview mirror housing within the set adjustment duration and comparing it with the position change amount threshold, effectively reducing the recognition blind area of the outside rearview mirror being disengaged from the locked state; after determining the disengagement from the lock, promptly report the indication information to the in-vehicle host, trigger the automatic reset mechanism of the outside rearview mirror, and execute the adjustment instruction to adjust the position of the outside rearview mirror after the reset is completed, thereby effectively reducing the problem that the rearview mirror cannot be adjusted due to the disengagement of the rearview mirror housing from the lock of the outside rearview mirror motor. In addition, through the intelligent status monitoring, fault diagnosis, and automatic reset mechanism, the vehicle can automatically reset the outside rearview mirror under extreme working conditions, greatly improving the intelligent level and safety performance of the whole vehicle, and reducing the possibility of the user driving without an outside rearview mirror, which has a positive significance for improving the user's driving experience and driving safety.

[0059] In some embodiments, resetting the outside rearview mirror includes: obtaining the current position of the rearview mirror housing and the historical position of the rearview mirror housing after being adjusted by the previous adjustment instruction; based on the position difference between the current position and the historical position, providing a driving voltage to drive the outside rearview mirror to reset.

[0060] Exemplarily, obtain the current position data of the rearview mirror housing collected by the position acquisition component, and obtain the current position data of the rearview mirror housing, such as the current angle θ_current; access the historical position data stored at the target storage location, such as in a non-volatile memory (Electrically Erasable Programmable Read-Only Memory, abbreviated as EEPROM), such as the historical position θ_last, which is the position of the rearview mirror housing recorded after the execution of the previous adjustment instruction; determine the position difference between the current position and the historical position, that is, Δθ2 = θ_current - θ_last, and this position difference refers to the offset between the current position of the rearview mirror and the historical position; based on the position difference, determine the required driving voltage, and the magnitude and direction of the driving voltage depend on the magnitude and direction of the position difference; further, provide a corresponding driving voltage to the motor according to the position difference to drive the external rearview mirror to reset.

[0061] In the embodiments of the present application, by obtaining the current position and the historical position of the rearview mirror housing, and determining a high-precision position difference based on the difference between the current position and the historical position, and further providing a corresponding driving voltage based on the position difference to drive the external rearview mirror to automatically reset; compared with the traditional method that relies on manual adjustment by the user, this automatic reset method not only improves the convenience of operation, but also ensures that the rearview mirror can quickly and accurately return to the preset position, thus significantly improving the user experience and driving safety.

[0062] In some embodiments, based on the position difference between the current position and the historical position, a driving voltage is provided to drive the external rearview mirror to reset, including: if the position difference is greater than 0, a positive driving voltage is provided to drive the external rearview mirror to reset; if the position difference is less than 0, a negative driving voltage is provided to drive the external rearview mirror to reset.

[0063] Exemplarily, assume that the position difference Δθ2 between the current position and the historical position is 10°, that is, Δθ2 is greater than 0, then a positive driving voltage, such as a 12V voltage, is provided to drive the external rearview mirror to reset, for example, in the clockwise direction; if Δθ2 is -10°, that is, Δθ2 is less than 0, then a negative driving voltage, such as a -12V voltage, is provided to drive the external rearview mirror to reset, for example, in the counterclockwise direction.

[0064] It can be understood that the magnitude of the driving voltage provided according to the position difference above is only an example. In actual applications, a driving voltage corresponding to the magnitude of the position difference can also be provided. For example, when Δθ2 is greater than 10°, a 12V voltage is provided; when Δθ2 is greater than 5° and less than or equal to 10°, a 9V voltage is provided; when Δθ2 is greater than 0° and less than or equal to 5°, a 6V voltage is provided; correspondingly, when Δθ2 is less than -10°, a -12V voltage is provided; when Δθ2 is greater than -10° and less than or equal to -5°, a -9V voltage is provided; when Δθ2 is greater than -5° and less than 0°, a -6V voltage is provided. Here, the magnitude of the forward driving voltage or the reverse driving voltage provided is not limited.

[0065] In the embodiments of the present application, by automatically determining the reset direction according to the mathematical sign (i.e., positive or negative) of the position difference, the precise control of the reset direction of the external mirror is realized, effectively solving the reset problem of the external mirror under complex working conditions, thereby providing a key technical guarantee for the intelligent driving system.

[0066] In some embodiments, after detecting that the external mirror is reset, an adjustment instruction is executed to adjust the position of the external mirror, including: detecting that the external mirror rotates, and determining that the external mirror reset is completed; executing the adjustment instruction to adjust the position of the external mirror.

[0067] Exemplarily, after receiving the reset instruction, the control module quickly responds and controls the relevant mechanism to release the locked state of the rearview mirror housing and the motor of the external mirror, so as to realize the state reset of the external mirror; at the same time, obtain the position information of the rearview mirror housing collected by the position acquisition component, and judge whether the position of the external mirror has changed based on the position information. When it is detected that the position of the external mirror has changed, that is, when the external mirror starts to rotate, it is determined that the external mirror reset is completed; further, the adjustment instruction is loaded again to drive the motor to adjust the position of the external mirror, such as automatic folding, position memory, or downward flipping when reversing, etc.

[0068] In some embodiments, after detecting that the external mirror is reset, an adjustment instruction is executed to adjust the position of the external mirror, including: detecting that the rearview mirror housing rotates to the historical position of the rearview mirror housing after being adjusted by the previous adjustment instruction, determining that the external mirror reset is completed; executing the adjustment instruction to adjust the position of the external mirror.

[0069] Exemplarily, after receiving a reset instruction, the control module quickly responds and controls the relevant mechanisms to release the locked state between the rearview mirror housing and the motor of the external rearview mirror, and drives the rearview mirror housing to rotate to the historical position of the rearview mirror housing after the last adjustment instruction is adjusted, so as to realize the state reset and position reset of the external rearview mirror; at the same time, obtain the position information of the rearview mirror housing collected by the position acquisition component, and judge whether the position of the external rearview mirror has changed based on the position information. When it is detected that the position of the external rearview mirror is consistent with the historical position of the rearview mirror housing after the last adjustment instruction is adjusted, that is, when the rearview mirror housing rotates to this historical position, it is determined that the external rearview mirror reset is completed; further, load the adjustment instruction again, and drive the motor to adjust the position of the external rearview mirror, such as automatic folding, position memory or downward flipping when reversing, etc.

[0070] In the embodiment of the present application, by automatically detecting the reset state of the external rearview mirror, it is possible to accurately judge when to execute the adjustment instruction. This automated adjustment method reduces human intervention, improves the accuracy and efficiency of operation; and the automated adjustment process reduces the frequent manual adjustment of the external rearview mirror, thereby reducing the possibility of mechanical wear and helping to extend the service life of the external rearview mirror.

[0071] In some embodiments, obtaining the position change amount of the rearview mirror housing of the external rearview mirror within a set adjustment duration includes: when starting to adjust the position of the external rearview mirror, obtaining the first position of the rearview mirror housing; after adjusting the position of the external rearview mirror for a set adjustment duration, obtaining the second position of the rearview mirror housing; based on the difference between the first position and the second position, obtaining the position change amount of the rearview mirror housing within the set adjustment duration.

[0072] Exemplarily, at the start moment of position adjustment when, the initial position θ_start of the rearview mirror housing is collected by the position acquisition component, and this position is used as the starting reference point for the adjustment process; according to the preset adjustment instruction, the position of the external rearview mirror is adjusted within a set adjustment duration Δt, such as 200 ms; when when, that is, after 200 ms, the real-time position (i.e., the second position) θ_current of the rearview mirror housing is obtained again through the position acquisition component; through the formula Δθ1 = |θ_start - θ_current|, calculate the difference between the first position θ_start and the second position θ_current and take the absolute value of this difference, so as to obtain the position change amount of the rearview mirror housing within the set adjustment duration Δt.

[0073] In the embodiment of the present application, by obtaining the first and second positions of the rearview mirror housing, the position change of the external rearview mirror during the adjustment process can be accurately monitored. This accuracy helps to accurately determine whether the rearview mirror housing is disengaged from the motor, thereby effectively ensuring the effectiveness of the external rearview mirror adjustment and the accuracy of the adjustment operation.

[0074] Figure 4 Another flowchart of the method for adjusting the external rearview mirror of a vehicle provided by an exemplary embodiment of the present application. The method for adjusting the external rearview mirror provided by the embodiment of the present application is applied to the control module in the external rearview mirror reset system of the vehicle. As Figure 4 shown, the method for adjusting the external rearview mirror of the vehicle includes the following steps:

[0075] S401. In response to an adjustment instruction for the external rearview mirror, adjust the position of the external rearview mirror, and obtain the position change amount of the rearview mirror housing of the external rearview mirror within a set adjustment duration.

[0076] Exemplarily, obtain the position change amount of the rearview mirror housing of the external rearview mirror within a set adjustment duration, such as 200 ms. Among them, the adjustment instruction includes, but is not limited to, a position memory call instruction, a reverse tilt trigger instruction, or a manual adjustment request instruction, etc.

[0077] S402. Determine whether the position change amount is less than or equal to the position change amount threshold.

[0078] If not, execute S403;

[0079] If so, execute S404.

[0080] S403. Continue to execute the adjustment instruction to complete the position adjustment of the external rearview mirror.

[0081] S404. Stop the position adjustment of the external rearview mirror, and report indication information to the vehicle's in-vehicle host. The indication information is used to represent that the rearview mirror housing is disengaged from the motor of the external rearview mirror. The in-vehicle host is used to issue a reset instruction for the external rearview mirror according to the indication information.

[0082] Exemplarily, when the position change amount Δθ1 is less than or equal to the position change amount threshold, such as 2°, immediately stop the position adjustment of the external rearview mirror, and report indication information to the in-vehicle host through the CAN bus. The indication information is, for example, the status code "0xE1". This status code is used to represent that the rearview mirror housing is disengaged from the motor of the external rearview mirror. The in-vehicle host is used to issue a reset instruction for the external rearview mirror according to the indication information.

[0083] S405. In response to receiving the reset instruction, obtain the current position of the rearview mirror housing and the historical position of the rearview mirror housing after being adjusted by the previous adjustment instruction.

[0084] S406. Determine the position difference between the current position and the historical position.

[0085] Exemplarily, the current position corresponds to θ_current, and the historical position corresponds to θ_last; the position difference Δθ2 = θ_current - θ_last.

[0086] S407. Determine whether the position difference is greater than 0.

[0087] If so, that is, the position difference is greater than 0, execute S408;

[0088] If not, that is, the position difference is less than 0, execute S409.

[0089] S408. Provide a forward driving voltage to drive the external rearview mirror to reset.

[0090] Among them, the forward driving voltage is, for example, 12V; correspondingly, the external rearview mirror is driven to reset, for example, in the clockwise direction.

[0091] S409. Provide a reverse driving voltage to drive the external rearview mirror to reset.

[0092] Among them, the reverse driving voltage is, for example, -12V; correspondingly, the external rearview mirror is driven to reset, for example, in the counterclockwise direction.

[0093] S410. After detecting that the external rearview mirror has been reset, execute the adjustment instruction to adjust the position of the external rearview mirror.

[0094] Exemplarily, continuously monitor the position change of the external rearview mirror. When it is detected that the external rearview mirror has completed the reset, load the adjustment instruction again to drive the motor to adjust the position of the external rearview mirror, such as automatic folding, position memory, or tilting down when reversing.

[0095] In summary, the present application has at least the following advantages:

[0096] First, by obtaining the position change amount of the rearview mirror housing within the set adjustment duration and comparing it with the position change amount threshold, it is possible to accurately determine whether the rearview mirror housing is disengaged from the motor of the external rearview mirror, effectively reducing the recognition blind area of the external rearview mirror being disengaged from the locked state; after determining the disengagement from the lock, promptly report the indication information to the vehicle-mounted host, trigger the automatic reset mechanism of the external rearview mirror, and execute the adjustment instruction to adjust the position of the external rearview mirror after the reset is completed, thereby effectively reducing the problem that the external rearview mirror cannot be adjusted due to the disengagement of the rearview mirror housing from the motor of the external rearview mirror. In addition, through the intelligent state monitoring, fault diagnosis, and automatic reset mechanism, the vehicle can automatically reset the external rearview mirror under extreme working conditions, greatly improving the intelligent level and safety performance of the whole vehicle, and reducing the possibility of the user driving without an external rearview mirror, which has a positive significance for improving the user's driving experience and driving safety.

[0097] II. By obtaining the current position and historical position of the rearview mirror housing, determining a high-precision position difference based on the difference between the current position and the historical position, and further providing a corresponding driving voltage based on the position difference to drive the outside rearview mirror to automatically reset; compared with the traditional method that relies on manual adjustment by the user, this automatic reset method not only improves the convenience of operation, but also ensures that the rearview mirror can quickly and accurately return to the preset position, thus significantly enhancing the user experience and driving safety.

[0098] III. By automatically determining the reset direction according to the mathematical sign (i.e., positive or negative) of the position difference, thereby achieving precise control of the reset direction of the outside rearview mirror, effectively solving the reset problem of the outside rearview mirror under complex working conditions, and thus providing key technical support for the intelligent driving system; and, by automatically detecting the reset state of the outside rearview mirror, it can accurately determine when to execute the adjustment instruction. This automatic adjustment method reduces human intervention, improves the accuracy and efficiency of operation; and the automatic adjustment process reduces the frequent manual adjustment of the outside rearview mirror, thereby reducing the possibility of mechanical wear and helping to extend the service life of the outside rearview mirror.

[0099] Figure 5 This is a schematic structural diagram of an outside rearview mirror reset system of a vehicle provided by an exemplary embodiment of the present application. As Figure 5 shown, the outside rearview mirror reset system 50 of the vehicle includes: a position acquisition component 51, a control module 52, and an in-vehicle host 53; wherein:

[0100] The position acquisition component 51 is arranged at one end of the rearview mirror housing close to the outside rearview mirror, and is used to monitor the position of the rearview mirror housing.

[0101] Among them, the position acquisition component 51 is specifically used to monitor the position or displacement of the rearview mirror housing in the Y-axis direction. The position acquisition component 51 may include, but is not limited to, a Hall effect sensor, an optical encoder, or a strain gauge force sensor, etc.

[0102] The control module 52 is connected to the position acquisition component and is used to execute the outside rearview mirror adjustment method of the vehicle described in any one of the above embodiments.

[0103] The in-vehicle host 53 is connected to the control module and is used to issue a reset instruction for the outside rearview mirror according to the indication information reported by the control module.

[0104] Exemplarily, the indication information is, for example, the status code "0xE1", which is used to characterize that the rearview mirror housing is disengaged from the lock of the outside rearview mirror motor. The in-vehicle host 53 is used to issue a reset instruction for the outside rearview mirror to the control module 52 according to the indication information.

[0105] In some embodiments, the in-vehicle host 53 is further configured to: display a prompt message for the unlocking of the exterior rearview mirror on the central control screen of the in-vehicle host.

[0106] Exemplarily, display a prompt message for the unlocking of the exterior rearview mirror in the status bar at the upper right corner of the central control screen. For example, when a mechanical abnormality is detected in the left exterior rearview mirror, a prompt message such as "Mechanical abnormality in the left exterior rearview mirror" is continuously displayed in the status bar until the abnormal situation is resolved.

[0107] In some embodiments, the in-vehicle host 53 is further configured to: pop up a function control for whether to reset on the central control screen of the in-vehicle host, and send a reset instruction to the control module when an operation instruction indicating reset is detected.

[0108] Exemplarily, Figure 6 is a schematic diagram of the function control interface for whether to reset provided by an exemplary embodiment of the present application. As Figure 6 shown, this interface includes an OK control and a Cancel control, aiming to provide a simple interaction option for the user to decide whether to perform the reset operation of the exterior rearview mirror. Correspondingly, when the user selects and clicks the OK control, a reset instruction will be immediately sent to the control module 52 to trigger the automatic reset process of the exterior rearview mirror; if the user selects the Cancel control, no reset instruction will be sent to the control module 52. In this case, the user needs to manually perform the reset operation of the exterior rearview mirror.

[0109] In some embodiments, the in-vehicle host 53 is further configured to: display a prompt message for the unlocking of the exterior rearview mirror on the central control screen of the in-vehicle host; meanwhile, pop up a function control for whether to reset on the central control screen of the in-vehicle host 53, and send a reset instruction to the control module when an operation instruction indicating reset is detected.

[0110] Exemplarily, display a prompt message for the unlocking of the exterior rearview mirror in the status bar at the upper right corner of the central control screen. For example, when a mechanical abnormality is detected in the left exterior rearview mirror, a prompt message such as "Mechanical abnormality in the left exterior rearview mirror" is continuously displayed in the status bar until the abnormal situation is resolved. Meanwhile, a function control interface for whether to reset is popped up on the central control screen of the in-vehicle host 53, and this interface includes an OK control and a Cancel control; correspondingly, when the user selects and clicks the OK control, a reset instruction will be immediately sent to the control module 52 to trigger the automatic reset process of the exterior rearview mirror; if the user selects the Cancel control, no reset instruction will be sent to the control module 52, and manual reset operation depends on manual intervention.

[0111] In the embodiments of the present application, by continuously displaying a prompt message at a prominent position on the central control screen, the user can perceive the abnormal state of the external rearview mirror in the first place; in addition, by providing a reset function control, the user can independently choose whether to perform automatic reset according to the actual situation, enhancing the flexibility of the operation.
