Technical Field

[0001] This application relates to the field of electronic rearview mirror technology, and in particular to a position management system, method, vehicle, and storage medium for an electronic exterior rearview mirror. Background Technology

[0002] With the development of the automotive industry and the advancement of technology, vehicle safety and convenience have become key concerns for manufacturers and consumers. Traditional optical exterior rearview mirrors are gradually being replaced by electronic exterior rearview mirrors, which not only provide a wider field of vision and higher safety, but also integrate more intelligent functions.

[0003] In related technologies, the field of electronic exterior rearview mirrors can be divided into "electronic exterior rearview mirrors with folding function" and "electronic exterior rearview mirrors without folding function". The electronic exterior rearview mirrors with folding function can achieve a simple manual folding function through a combination of spring pins, and can achieve an electric folding function by integrating a folding motor, so as to reduce the width occupied when parking the vehicle and protect the exterior rearview mirror from external collision damage.

[0004] However, the relevant technologies are insufficient in ensuring that the electronic exterior rearview mirrors are in the correct working position, especially in extreme weather conditions. For example, low temperatures may cause the exterior rearview mirrors to freeze in their non-working positions, thus preventing them from unfolding to the preset angle. This would prevent the camera from capturing accurate image information, which poses a potential threat to driving safety and urgently needs to be improved. Summary of the Invention

[0026] Figure 6 This is a structural schematic diagram of a vehicle provided according to an embodiment of this application. Detailed Implementation

[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0028] The following description, with reference to the accompanying drawings, outlines an electronic exterior rearview mirror location management system, method, vehicle, and storage medium according to embodiments of this application. The aforementioned technologies mentioned in the background section have shortcomings in ensuring that electronic exterior rearview mirrors are in the correct working position, especially under extreme weather conditions. For example, low temperatures may cause the exterior rearview mirrors to freeze in their non-working positions, preventing them from unfolding to the preset angle and preventing the camera from capturing accurate image information. This poses a potential threat to driving safety. This application provides a position management system for electronic exterior rearview mirrors. In this system, a temperature sensor and microswitch integrated into the folding area of ​​the electronic exterior rearview mirror can detect whether the mirror is in a non-working state due to human factors or environmental conditions. The signal is sent to the ECU, which processes and judges the state of the mirror. If an abnormality is detected, such as the mirror failing to unfold due to freezing, or an abnormal position when the temperature is above freezing, the ECU will issue a warning to the user through the central control screen and provide guidance on solutions to ensure the mirror returns to normal operation. Through intelligent management and a user-friendly prompt mechanism, driving safety is ensured, the functionality and reliability of the electronic exterior rearview mirror are enhanced, and a safer and more convenient driving experience is provided for the driver. This solves the shortcomings of related technologies in ensuring that electronic exterior rearview mirrors are in the correct working position, especially in extreme weather conditions, such as low temperatures, which may cause the exterior rearview mirrors to freeze in their non-working positions and thus fail to unfold to the preset angle, preventing the camera from collecting accurate image information, which poses a potential threat to driving safety.

[0029] Specifically, Figure 1 This is a schematic diagram of the structure of an electronic exterior rearview mirror position management method provided in an embodiment of this application.

[0030] like Figure 1 As shown, the electronic exterior rearview mirror position management system 10 includes:

[0031] Temperature sensor 100 is located at the folding part of the electronic exterior rearview mirror and is used to collect the ambient temperature signal of the environment in which the electronic exterior rearview mirror is located.

[0032] It is understandable that, such as Figure 2As shown, the electronic exterior rearview mirror in this embodiment has a folding function. The electronic exterior rearview mirror with the folding function has two movement states: folding inward and folding outward. The lens rotates back and forth around the folding axis. This embodiment can collect vehicle image signals through the electronic exterior rearview mirror with the folding function, providing support for the subsequent transmission of these image signals to the vehicle's internal system for processing and display.

[0033] In actual implementation, the temperature sensor 100 in this embodiment is disposed at the folding part of the electronic rearview mirror to collect the ambient temperature signal of the environment in which the electronic rearview mirror is located, so as to ensure that the local temperature changes that may affect the operation of the electronic rearview mirror can be accurately detected.

[0034] The temperature sensor 100 in this embodiment not only helps to achieve accurate monitoring of ambient temperature, but also achieves multiple goals such as improving safety, enhancing user experience, and increasing the reliability of electronic rearview mirrors through the effective use of this data.

[0035] Microswitch 200 is located at the folding point of the electronic exterior rearview mirror and is used to collect the opening and closing circuit signal corresponding to the opening and closing circuit of the electronic exterior rearview mirror.

[0036] It is understood that, in the embodiments of this application, a temperature sensor 100 and a micro switch 200 are respectively placed at the folding part of the electronic exterior rearview mirror and fixed inside the lens of the electronic exterior rearview mirror with screws or clips.

[0037] In actual implementation, the micro switch 200 in this embodiment is set at the folding part of the electronic rearview mirror to collect the opening and closing circuit signals corresponding to the opening and closing circuit of the electronic rearview mirror. This not only realizes accurate monitoring of the position status of the electronic rearview mirror, but also enhances the safety, reliability and user experience of the system by effectively utilizing this information.

[0038] In this embodiment, the temperature sensor 100 and the micro switch 200 are placed at the folding part of the electronic exterior rearview mirror to form an electronic exterior rearview mirror assembly, thereby providing support for the subsequent connection of the electronic exterior rearview mirror assembly to the ECU via a wiring harness.

[0039] The position management module 300 is connected to the electronic exterior rearview mirror, the temperature sensor 100 and the micro switch 200. It is used to determine at least one position management action of the electronic exterior rearview mirror based on the ambient temperature signal collected by the temperature sensor 100 and the open / closed signal collected by the micro switch 200, and to execute at least one position management action.

[0040] It is understood that the position management module 300 in this application embodiment can be an electronic control unit (ECU), which is connected to the central control screen via a wiring harness; the wiring harnesses of the temperature sensor 100 and the micro switch 200 are connected to the vehicle ECU along with the wiring harness of the exterior rearview mirror assembly.

[0041] In actual implementation, the position management module 300 in this embodiment is connected to the electronic exterior rearview mirror, the temperature sensor 100, and the micro switch 200. It is used to receive the ambient temperature signal collected by the temperature sensor 100 and the open / closed circuit signal collected by the micro switch 200 to determine at least one position management action of the electronic exterior rearview mirror and execute at least one position management action. For example, when the temperature is detected to be below freezing and the micro switch is in the open circuit state, the driver is immediately prompted to manually de-ice or attempt to restart automatically to ensure that the electronic exterior rearview mirror is always kept in the best working state and to ensure driving safety.

[0042] In this embodiment, the ECU can collect the opening and closing signals of the micro switch 200 and the temperature of the temperature sensor 100 to perform preset operations. The ECU can detect the working position of the electronic rearview mirror to avoid the electronic rearview mirror from being in a non-working state due to human factors (unintentional bumps) or environmental factors (such as low temperature freezing), thereby affecting the driver's driving safety.

[0043] Optionally, in one embodiment of this application, the position management module 300 is further configured to perform frequency detection on the state of the micro switch 200 at preset time intervals when the micro switch 200 is detected to be in a closed state, so as to determine that the electronic exterior rearview mirror is in a working position that meets the preset correct conditions.

[0044] It is understood that the working position with preset correct conditions in the embodiments of this application can be the correct lens working position.

[0045] In actual implementation, such as Figure 3 As shown, in this embodiment of the application, the position management module 300 is further used to ensure that when the micro switch 200 is detected to be in a closed state, the display screen does not make any prompts, the vehicle can start normally, and the ECU can perform frequency detection through a preset time to always ensure that the lens is in the correct working position.

[0046] For example, in embodiments of this application, the detection cycle can be appropriately extended when the vehicle is stationary or parked, for example, once every 5 to 10 minutes; as another example, after the vehicle enters the driving state, the detection cycle can be shortened to ensure higher safety, for example, once every 2 to 5 seconds.

[0047] In this embodiment, when the lens of the electronic rearview mirror is in the forward or backward folding state, the position and angle of the camera will change due to the folding, resulting in inaccurate images and affecting driving safety. When the lens is in the forward or backward folding state, the micro switch 200 is in the open circuit state. When the ECU receives the open circuit state command, it collects the temperature signal of the temperature sensor 100 and outputs the signal to the display screen according to the preset logic.

[0048] Optionally, in one embodiment of this application, the position management module 300 further includes: a first judgment unit, configured to determine whether the ambient temperature signal is less than or equal to a preset temperature threshold when the micro switch 200 is detected to be in an open circuit state; a first display unit, configured to display restart information or ignore information indicating that the electronic exterior rearview mirror meets the preset ice-breaking conditions when the ambient temperature signal is less than or equal to the preset temperature threshold; a first management unit, configured to execute at least one position management action of the electronic exterior rearview mirror according to the restart information indicating that the preset ice-breaking conditions are met, to manage the electronic exterior rearview mirror to restart the folding function twice, and to allow the vehicle to start when the micro switch is in a closed state, otherwise, to prompt the electronic exterior rearview mirror ice-breaking failure information; and a first release unit, configured to release the vehicle start restriction according to the ignore information indicating that the preset ice-breaking conditions are met.

[0049] It is understood that the preset temperature threshold in this application embodiment can be 0 degrees Celsius; the restart information that meets the preset ice-breaking conditions in this application embodiment can be the restart information of "The electronic exterior rearview mirror is frozen. Please manually break the ice and then click restart".

[0050] For example, in this embodiment, when the microswitch 200 is detected to be in an open circuit state, it can determine whether the ambient temperature signal collected by the temperature sensor 100 is less than or equal to 0 degrees Celsius. Using the first display unit, if the ambient temperature signal is less than or equal to 0 degrees Celsius, the vehicle's large screen will display a message: "The electronic exterior rearview mirror is frozen. Please manually de-ice it and then click 'Restart'." The UI interface has two states: "Restart" on the left and "Ignore" on the right, displaying restart information indicating that the electronic exterior rearview mirror meets the preset de-iceing conditions, or ignoring the message. If the user clicks "Restart," this embodiment can execute at least one position management action for the electronic exterior rearview mirror, managing the folding function of the electronic exterior rearview mirror to restart twice. When the microswitch 200 is in a closed state, a 10-second countdown pop-up message "Electronic exterior rearview mirror de-iceing completed, vehicle can be started" disappears, allowing the vehicle to start. If the microswitch 200 is detected to be in an open circuit state, a message indicating de-iceing failure of the electronic exterior rearview mirror is displayed, with a 10-second countdown message indicating "De-iceing failed," and then the "Restart" pop-up message appears. In this embodiment, when the user clicks "ignore", the first release unit can release the vehicle's starting restriction based on the ignore information that meets the preset ice-breaking conditions.

[0051] This embodiment of the application integrates the functions of a micro switch 200, a temperature sensor 100, and a position management module 300 to achieve intelligent management and user-friendly prompts for the electronic exterior rearview mirror in low-temperature and frozen conditions. Through clear visual prompts and guidance, it ensures that drivers can correctly handle the freezing problem of the electronic exterior rearview mirror in low-temperature conditions, avoiding safety hazards caused by obstructed vision. Through intelligent management and user-friendly prompt mechanisms, the reliability and user experience of the electronic exterior rearview mirror in low-temperature and frozen conditions are significantly improved, ultimately achieving higher driving safety and user satisfaction.

[0052] It should be noted that the preset ice-breaking conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0053] Optionally, in one embodiment of this application, the position management module 300 further includes: a second judgment unit, configured to determine whether the ambient temperature signal is greater than a preset temperature threshold when the micro switch 200 is detected to be in an open circuit state; a second display unit, configured to display restart information or ignore information of the electronic exterior rearview mirror meeting preset abnormal conditions when the ambient temperature signal is greater than the preset temperature threshold; a second management unit, configured to perform at least one position management action of the electronic exterior rearview mirror based on the restart information meeting preset abnormal conditions, to manage the electronic exterior rearview mirror to restart the folding function twice, and allow the vehicle to start when the micro switch 200 is in a closed state, otherwise, prompt the user with the corresponding error information and suggest repairing the electronic exterior rearview mirror; and a second release unit, configured to release the vehicle's start restriction based on the ignore information meeting preset abnormal conditions.

[0054] It is understood that, in the embodiments of this application, the restart information that meets the preset abnormal conditions can be the restart information of "electronic rearview mirror is abnormal and needs to be restarted".

[0055] In actual implementation, this embodiment can determine whether the ambient temperature signal is greater than 0 degrees Celsius when the microswitch 200 is detected to be in an open circuit state. If the ambient temperature signal is greater than 0 degrees Celsius, the vehicle's large screen will display "Electronic exterior rearview mirror malfunction, function needs to be restarted." The UI interface has two states: "Restart" on the left and "Ignore" on the right, displaying restart information or ignore information indicating that the electronic exterior rearview mirror meets preset malfunction conditions. If the user clicks "Restart," this embodiment can execute at least one position management action of the electronic exterior rearview mirror, managing the electronic exterior rearview mirror to restart the folding function twice. If the microswitch 200 is in a closed state, a "Vehicle can be started" countdown pop-up will disappear after 10 seconds, allowing the vehicle to start. If the microswitch 200 is detected to be in an open circuit state, a "Electronic exterior rearview mirror malfunction, please go to a 4S shop for repair as soon as possible" countdown will occur after 10 seconds, returning to the aforementioned "Restart" pop-up. This embodiment can also use the second release unit to release the vehicle's starting restriction based on the ignore information indicating that the preset malfunction conditions are met when the user clicks "Ignore."

[0056] This application embodiment can further determine whether the ambient temperature signal is greater than 0 degrees Celsius when the microswitch 200 is detected to be in an open circuit state, and provide corresponding prompts and processing mechanisms according to different situations. This ensures that the driver can understand the working status of the electronic exterior rearview mirror in a timely manner, especially when abnormalities occur under non-icy conditions, avoiding safety hazards caused by obstructed vision. Through intelligent management and user-friendly prompt mechanisms, the reliability and user experience of the electronic exterior rearview mirror in abnormal situations are significantly improved under non-icy conditions.

[0057] It should be noted that the preset abnormal conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0058] Display module 400 is used to generate at least one prompt message based on at least one location management action, and to display at least one prompt message.

[0059] Understandably, the display module 400 can be a central control screen.

[0060] In actual implementation, such as Figure 4 As shown, in this embodiment of the application, a prompt message corresponding to the electronic exterior rearview mirror can be generated based on at least one location management action, and the prompt message can be displayed to ensure that the driver is notified immediately when any abnormality is detected or user intervention is required. For example, when the temperature sensor 100 detects a risk of low temperature freezing or the micro switch reports an abnormal position status, the central control screen will quickly pop up the corresponding warning message to inform the user of the current situation and suggested operating steps.

[0061] The embodiments of this application can provide prompts to users on the central control screen. Through intelligent management and user-friendly prompting mechanisms, the interactivity and usability of the system are greatly improved, ultimately achieving higher driving safety and user satisfaction.

[0062] Optionally, in one embodiment of this application, the electronic exterior rearview mirror position management system 10 further includes: an acquisition module for acquiring at least one of the environmental data of temperature, humidity and light intensity of the environment in which the electronic exterior rearview mirror is located; and an adjustment module for adjusting the working mode of the electronic exterior rearview mirror based on the at least one of the environmental data.

[0063] In this embodiment, the acquisition module can acquire environmental data such as temperature, humidity and light intensity of the environment in which the electronic rearview mirror is located, so as to accurately understand the current working environment and make a more appropriate response. In this embodiment, the adjustment module can adjust the working mode of the electronic rearview mirror based on at least one environmental data to ensure that the electronic rearview mirror is always in the optimal state. For example, the night vision enhancement mode can be activated under low light conditions, and the heat dissipation mechanism can be activated under high temperature conditions.

[0064] The electronic rearview mirror position management system proposed in this application can detect whether the rearview mirror is in a non-working state due to human factors or environmental conditions by using a temperature sensor and microswitch integrated at the folding point of the electronic rearview mirror. The system sends a signal to the ECU, which processes and judges the state of the rearview mirror. If an abnormality is detected, such as the rearview mirror failing to unfold properly due to freezing, or the rearview mirror being in an abnormal position when the temperature is above freezing, the ECU will issue a corresponding warning to the user through the central control screen and provide guidance on troubleshooting steps to ensure the rearview mirror can return to normal working status. Through intelligent management and a user-friendly prompt mechanism, driving safety is ensured, the functionality and reliability of the electronic rearview mirror are enhanced, and a safer and more convenient driving experience is provided for the driver. This solves the shortcomings of related technologies in ensuring that the electronic rearview mirror is in the correct working position, especially under extreme weather conditions, such as low temperatures, which may cause the rearview mirror to freeze in its non-working position and fail to unfold to the preset angle, preventing the camera from capturing accurate image information, thus posing a potential threat to driving safety.

[0065] Next, the position management device for an electronic exterior rearview mirror according to an embodiment of this application is described with reference to the accompanying drawings.

[0066] Figure 5 This is a schematic diagram of the position management device for the electronic exterior rearview mirror according to an embodiment of this application.

[0067] like Figure 5 As shown, the electronic exterior rearview mirror position management device 10 includes:

[0068] In step S501, the ambient temperature signal and the corresponding switching circuit signal are acquired.

[0069] In step S502, based on the ambient temperature signal and the open / closed signal, at least one position management action of the electronic exterior rearview mirror is determined and executed.

[0070] In step S503, at least one prompt message is generated based on at least one location management action, and at least one prompt message is displayed.

[0071] Optionally, in one embodiment of this application, determining at least one position management action of the electronic exterior rearview mirror includes: when a micro switch is detected to be in a closed state, performing frequency detection on the state of the micro switch at preset time intervals to determine that the electronic exterior rearview mirror is in a working position that meets preset correct conditions.

[0072] Optionally, in one embodiment of this application, performing at least one position management action further includes: determining whether the ambient temperature signal is less than or equal to a preset temperature threshold; if the ambient temperature signal is less than or equal to the preset temperature threshold, displaying restart information or ignore information indicating that the electronic exterior rearview mirror meets preset ice-breaking conditions; performing at least one position management action of the electronic exterior rearview mirror based on the restart information indicating that the preset ice-breaking conditions are met, to manage the electronic exterior rearview mirror to restart the folding function twice, and allowing the vehicle to start when the micro switch is in the closed state; otherwise, displaying information indicating that the electronic exterior rearview mirror failed to break ice; and lifting the vehicle's starting restriction based on the ignore information indicating that the preset ice-breaking conditions are met.

[0073] Optionally, in one embodiment of this application, performing at least one position management action further includes: determining whether the ambient temperature signal is greater than a preset temperature threshold; if the ambient temperature signal is greater than the preset temperature threshold, displaying restart information or ignore information indicating that the electronic exterior rearview mirror meets preset abnormal conditions; based on the restart information indicating that the preset abnormal conditions are met, performing at least one position management action of the electronic exterior rearview mirror to manage the electronic exterior rearview mirror to restart the folding function twice, and allowing the vehicle to start when the micro switch is in the closed state; otherwise, prompting the user with the corresponding error information and suggesting repair of the electronic exterior rearview mirror; and lifting the vehicle's starting restriction based on the ignore information indicating that the preset abnormal conditions are met.

[0074] Optionally, in one embodiment of this application, the method further includes: acquiring at least one of environmental data, including temperature, humidity, and light intensity; and adjusting the working mode of the electronic rearview mirror based on the at least one environmental data.

[0075] It should be noted that the foregoing explanation of the position management system embodiment for the electronic exterior rearview mirror also applies to the position management method of the electronic exterior rearview mirror in this embodiment, and will not be repeated here.

[0076] The electronic exterior rearview mirror position management method proposed in this application can detect whether the exterior rearview mirror is in a non-working state due to human factors or environmental conditions by integrating a temperature sensor and a micro switch at the folding point of the electronic exterior rearview mirror. The signal is sent to the ECU, which processes and judges the state of the exterior rearview mirror. If an abnormality is detected, such as the exterior rearview mirror failing to unfold properly due to freezing, or the exterior rearview mirror being in an abnormal position when the temperature is above freezing, the ECU will issue a corresponding warning to the user through the central control screen and provide guidance on troubleshooting steps to ensure that the exterior rearview mirror can return to normal working status. Through intelligent management and a user-friendly prompt mechanism, driving safety is ensured, the functionality and reliability of the electronic exterior rearview mirror are enhanced, and a safer and more convenient driving experience is provided for the driver. This solves the shortcomings in related technologies in ensuring that the electronic exterior rearview mirror is in the correct working position, especially under extreme weather conditions, such as low temperatures, which may cause the exterior rearview mirror to freeze in its non-working position and fail to unfold to the preset angle, preventing the camera from capturing accurate image information, thus posing a potential threat to driving safety.
