Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an environmental information detection method, device, storage medium, and vehicle. Background Technology

[0002] With the development of industrial technology in the automotive industry, vehicles are increasingly involved in people's daily lives and work. Faced with various scenarios, vehicle function development is gradually moving towards intelligent services, and electronic exterior rearview mirror systems are one such direction. Electronic exterior rearview mirror systems can collect information about the environment behind the vehicle through onboard cameras and display it on a connected electronic screen. However, when the electronic exterior rearview mirror system malfunctions, the driver cannot clearly see the information about the environment behind the vehicle. Therefore, an environmental information detection method is needed to accurately detect the information about the environment behind the vehicle, thereby assisting users in controlling and parking the vehicle. Summary of the Invention

[0003] This application provides an environmental information detection method, device, storage medium, and vehicle, which can solve the technical problem in the related art that the vehicle condition and environmental information cannot be obtained after the electronic rearview mirror malfunctions, causing driving safety hazards.

[0004] In a first aspect, embodiments of this application provide an environmental information detection method, the method comprising:

[0005] In response to a fault signal from the electronic exterior rearview mirror system, determine the fault location corresponding to the fault signal and determine the rear corner detection device and display screen corresponding to the fault location;

[0006] Based on the first rear corner environmental information collected by the rear corner detection device, the rear corner detection device is controlled to be in a preset detection mode;

[0007] The device receives second rear corner environmental information collected by the rear corner detection device when it is in a preset detection mode, and displays the corresponding display content on the displayable screen.

[0008] Secondly, embodiments of this application provide an environmental information detection device, the device comprising:

[0009] The rearview fault determination module is used to respond to the fault signal of the electronic exterior rearview mirror system, determine the fault location corresponding to the fault signal of the electronic exterior rearview mirror system, and determine the rear corner detection device and display screen corresponding to the fault location;

[0010] The detection device activation module is used to control the rear corner detection device to be in a preset detection mode based on the first rear corner environmental information collected by the rear corner detection device;

[0011] The environmental information receiving module is used to receive the second rear corner environmental information collected by the rear corner detection device when it is in a preset detection mode, and to display the corresponding display content of the second rear corner environmental information on the displayable screen.

[0012] Thirdly, embodiments of this application provide a computer storage medium storing a plurality of instructions adapted for loading by a processor and executing the steps of the method described above.

[0013] Fourthly, embodiments of this application provide a vehicle including a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being adapted to be loaded by the processor and to execute the steps of the method described above.

[0014] The beneficial effects of the technical solutions provided in some embodiments of this application include at least the following:

[0015] This application provides an environmental information detection method. In response to a fault signal from an electronic rearview mirror system, it determines the fault location corresponding to the fault signal, as well as the corresponding rear-angle detection device and display screen. Based on the first rear-angle environmental information collected by the rear-angle detection device, it controls the rear-angle detection device to enter a preset detection mode. It receives second rear-angle environmental information collected by the rear-angle detection device while in the preset detection mode, and displays the corresponding content on the display screen. Since the rear-angle detection device installed on the vehicle body can detect objects and their distances in the environment behind the vehicle, when a fault signal from the electronic rearview mirror system occurs, the rear-angle detection device corresponding to the fault location can be used to detect the environmental information behind the vehicle at the fault location. Furthermore, the rear-angle detection device can adaptively adjust itself to the preset detection mode based on the environmental information, thereby flexibly and accurately collecting the second rear-angle environmental information. The detected environmental information is then displayed on the available display screen. This allows for accurate display of the rear-angle environment to the user in rearview mirror fault scenarios, effectively assisting the user in safe vehicle control, improving the reliability and safety of the vehicle's rearview system, and ensuring user driving safety.

[0025] To make the features and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0027] With the integration and advancement of automotive R&D technology and artificial intelligence technology, intelligent vehicle services are becoming an increasingly important highlight and selling point for vehicles in diverse scenarios. Among these, electronic exterior rearview mirror systems are one of the key directions of intelligent vehicle services.

[0028] Traditional optical rearview mirrors, including interior and exterior mirrors, have a history of over a century. They provide drivers with information about pedestrians, vehicles, and roads behind and to the sides of the vehicle, and their importance to driving safety is widely recognized. However, traditional exterior mirrors have some drawbacks. First, they increase wind resistance. The higher the drag coefficient, the greater the wind resistance the vehicle has to overcome, resulting in higher fuel consumption. Currently, most vehicles have a drag coefficient of around 0.2 to 0.4, while exterior mirrors contribute 0.01 to 0.03 to the drag coefficient, a significant factor that can affect the vehicle's range. Second, the accuracy of the image reflected in traditional rearview mirrors is affected by actual conditions. For example, in heavy rain or darkness, the image reflected in the mirror often becomes blurry and unclear, severely impacting the user's observation and creating safety hazards for vehicle control and driving. Third, traditional rearview mirrors often have blind spots. Due to the size of the mirror and the adjustable angle, the information they can provide is relatively limited. In addition, passengers in other seats may also obstruct the driver's view, resulting in a lack of information reception and thus affecting driving safety.

[0029] Building upon this foundation, during the development of intelligent vehicle functions and services, an Electronic Rearview Mirror System (CMS) was developed. This system is a combination of a camera and a display, enhancing the driver's visual perception of the vehicle's surroundings and rear sides, further improving driving safety and comfort. Specifically, it uses an external camera to capture environmental images of the vehicle's surroundings and rear sides, processes the data, and displays the images on a screen inside the vehicle's cabin. It also integrates blind spot warning and obstacle detection functions. The electronic rearview mirror boasts advantages such as small size, retractability, low wind resistance, clear image quality, and a more technologically advanced feel. It allows drivers to perceive all-around road conditions without significantly altering their viewing angle, gradually replacing traditional rearview mirror systems in vehicles. Compared to traditional optical rearview mirrors, it offers advantages such as reduced vehicle weight, reduced drag and noise, and resolution of blind spot issues.

[0030] Because vehicles using electronic rearview systems are susceptible to malfunction, and given the significant impact of these systems on user safety, a malfunction in the rearview mirrors can cause users to lose awareness of the environment to the rear corners and sides of the vehicle, posing a significant threat to driving and vehicle control safety.

[0031] Therefore, this application provides an environmental information detection method that, in response to a fault signal from an electronic rearview mirror system, determines the fault location corresponding to the fault signal, as well as the rear corner detection device and display screen corresponding to the fault location; controls the rear corner detection device to be in a preset detection mode based on the first rear corner environmental information collected by the rear corner detection device; receives the second rear corner environmental information collected by the rear corner detection device when it is in the preset detection mode, and displays the display content corresponding to the second rear corner environmental information on the display screen, thereby solving the technical problem that the vehicle condition environment information cannot be obtained after the electronic rearview mirror malfunctions, causing driving safety hazards.

[0032] Please see Figure 1 , Figure 1 This is an exemplary system architecture diagram of an environmental information detection method provided in an embodiment of this application.

[0033] like Figure 1 As shown, the system architecture may include vehicle 101, network 102, and server 103. Network 102 serves as the medium for providing a communication link between vehicle 101 and server 103. Network 102 may include various types of wired or wireless communication links, such as: wired communication links including fiber optic, twisted-pair, or coaxial cable; and wireless communication links including Bluetooth, Wireless-Fidelity (Wi-Fi), or microwave communication links, etc.

[0034] Vehicle 101 can interact with server 103 via network 102 to receive or send messages to server 103, or vehicle 101 can interact with server 103 via network 102 to receive messages or data sent to server 103 by other users. Vehicle 101 can be hardware or software. When vehicle 101 is hardware, it can be various electronic devices, including but not limited to smartwatches, smartphones, tablets, laptops, and desktop computers. When vehicle 101 is software, it can be installed in the aforementioned electronic devices, and can be implemented as multiple software programs or software modules (e.g., to provide distributed services) or as a single software program or software module; no specific limitation is made here.

[0035] In this embodiment, when the vehicle 101 responds to a fault signal from the electronic exterior rearview mirror system, it determines the fault location corresponding to the fault signal and the rear corner detection device and display screen corresponding to the fault location. Further, the vehicle 101 controls the rear corner detection device to be in a preset detection mode based on the first rear corner environmental information collected by the rear corner detection device. At this time, the vehicle 101 can receive the second rear corner environmental information collected by the rear corner detection device when it is in the preset detection mode, and display the display content corresponding to the second rear corner environmental information on the display screen.

[0036] Server 103 can be a business server providing various services. It should be noted that server 103 can be either hardware or software. When server 103 is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or as a single server. When server 103 is software, it can be implemented as multiple software programs or software modules (e.g., used to provide distributed services), or as a single software program or software module; no specific limitations are made here.

[0037] Alternatively, the system architecture may not include server 103. In other words, server 103 may be an optional device in the embodiments of this specification. That is, the method provided in the embodiments of this specification can be applied to a system structure that only includes vehicle 101. The embodiments of this application do not limit this.

[0038] It should be understood that Figure 1 The number of vehicles, networks, and servers shown is only illustrative; the number can be any number depending on the implementation requirements.

[0039] Please see Figure 2 , Figure 2 This is a flowchart illustrating an environmental information detection method provided in an embodiment of this application. The executing entity in this embodiment can be a vehicle performing environmental information detection, a processor within the vehicle performing the environmental information detection method, or an environmental information detection service within the vehicle performing the environmental information detection method. For ease of description, the following example uses the electronic exterior rearview controller in the vehicle's electronic exterior rearview mirror system as the processor to illustrate the specific execution process of the environmental information detection method.

[0040] like Figure 2 As shown, environmental information detection methods can include at least:

[0041] S202. In response to a fault signal from the electronic exterior rearview mirror system, determine the fault location corresponding to the fault signal and determine the rear corner detection device and display screen corresponding to the fault location.

[0042] Optionally, drivers need to use interior and exterior rearview mirrors to observe road and vehicle conditions to the sides and rear of the vehicle during driving, facilitating vehicle control. Therefore, exterior rearview mirrors are closely related to driving safety. In modern intelligent vehicles, electronic exterior rearview mirrors are an important component. They use high-quality cameras to capture environmental images, process these images digitally, and display them on a built-in electronic rearview display screen, providing users with a clear and accurate view of the rear environment. However, when electronic exterior rearview mirrors malfunction, users cannot see the side and rear environment of the vehicle, posing a significant safety hazard.

[0043] Optionally, to provide more accurate information about the surrounding environment to guide users when parking or reversing, vehicles are typically equipped with detection sensors capable of detecting obstacles and moving objects within a certain range around the vehicle. Therefore, to help users understand the rear view environment even when the electronic side mirrors malfunction, the vehicle's existing detection sensors can be used to detect the surrounding environment, replacing the currently missing rear view information and ensuring user safety while driving.

[0044] Specifically, rear corner detection devices, as existing vehicle detection equipment used for collision avoidance and parking, are commonly installed at the left and right rear corners of a vehicle to achieve all-around environmental monitoring around the vehicle. When multiple rear corner detection devices are present in a vehicle, and the electronic exterior rearview mirror malfunctions, depending on the specific circumstances of the malfunction, one or more of these devices may be required. That is, when the electronic exterior rearview mirror malfunctions, the system first needs to respond to the fault signal emitted by the faulty component to perform a simple analysis and judgment of the rearview malfunction information, identifying the corresponding rear corner detection device. Furthermore, to provide environmental information to the user, a suitable display screen for displaying the environmental information collected by the rear corner detection device also needs to be determined. This process allows for the selection of effective rear corner detection devices and display screens from all available rear corner detection devices, addressing the problem of insufficient rear corner environmental information.

[0045] Further, please refer to Figure 3 , Figure 3 This is a schematic diagram illustrating a control method for an electronic exterior rearview mirror provided in an embodiment of this application. Figure 3 As shown, an electronic exterior rearview mirror system typically includes three categories of components: an electronic exterior rearview camera, an electronic exterior rearview display, and an electronic exterior rearview controller. There is one electronic exterior rearview camera and one electronic exterior rearview display on each side. Common electronic exterior rearview mirror systems have two control schemes; for the first one, please refer to [link to relevant documentation]. Figure 3(A) Two electronic exterior rearview cameras are connected to the same electronic exterior rearview controller via a coaxial cable, such as an LVDS harness. One electronic exterior rearview controller drives the left and right electronic exterior rearview displays to show images. For the second method, please refer to [link / reference]. Figure 3 (B) Two electronic rearview cameras are connected to two electronic rearview controllers via coaxial cables, such as LVDS harnesses. The two electronic rearview controllers drive the left and right electronic rearview displays to display images.

[0046] Therefore, when electronic exterior rearview mirrors malfunction, the source of the fault is generally the electronic exterior rearview camera or the electronic exterior rearview display screen. Thus, the fault source of the electronic exterior rearview mirror system fault signal is either a fault in the electronic exterior rearview camera or a fault in the electronic exterior rearview display screen. It should be noted that when the fault source is a fault in either the electronic exterior rearview camera or the electronic exterior rearview display screen, the electronic exterior rearview controller responds to the electronic exterior rearview mirror system fault signal and executes subsequent steps. However, in practical applications, there may also be situations where the electronic exterior rearview controller malfunctions. If the electronic exterior rearview controller malfunctions, other controllers in the vehicle, such as the vehicle controller, will directly control the vehicle based on the detection results from the rear corner detection device to ensure the user's driving safety.

[0047] Optionally, when a fault signal appears in the electronic exterior rearview mirror system, it indicates that the system is malfunctioning. This malfunction results in a missing view of the rearview image, and the location of the missing image is the fault location corresponding to the electronic exterior rearview mirror system. For example, if the fault signal indicates a malfunction in the electronic exterior rearview camera on the left side of the vehicle, then the left side of the vehicle is the fault location where the rearview image is missing. In special cases, if the fault signal indicates a malfunction in the electronic exterior rearview controller, then both the left and right sides of the vehicle are fault locations where the rearview image is missing. Therefore, when determining the rear corner detection device and display screen corresponding to the electronic exterior rearview mirror system fault signal, the fault location can be determined based on the fault location indicated by the fault signal. This ensures that the rear corner detection device and display screen at the effective location provide the user with the necessary rear corner environmental information.

[0048] S204. Based on the first rear corner environmental information collected by the rear corner detection device, control the rear corner detection device to be in the preset detection mode.

[0049] Optionally, during vehicle operation, in addition to fixed obstacles, moving objects such as people and other vehicles may appear in the environment behind the vehicle. The relative distance and position of these moving objects to the vehicle may change irregularly at any time. Therefore, in order to collect more accurate rear-angle environmental information through the rear-angle detection device, the rear-angle detection device can have an adaptive monitoring function. The adaptive monitoring function means that when the rear-angle detection device collects the first rear-angle environmental information, which may contain information about moving objects, the rear-angle detection device can adaptively switch to a preset detection mode based on the first rear-angle environmental information. For example, if the first rear-angle environmental information indicates that the moving object is far away, then a mode that can detect objects at a greater distance will be activated; if the first rear-angle environmental information indicates that the moving object is close, then a mode that can detect objects at a closer distance will be activated.

[0050] Optionally, after determining the required rear corner detection device and the display screen, the rear corner detection device can be controlled to enter a preset detection mode based on the first rear corner environmental information collected by the rear corner detection device. The preset detection mode is the detection mode corresponding to the first rear corner environmental information that has been set in advance. In this way, the rear corner detection device adjusts its own detection mode according to the first rear corner environmental information it has collected, so as to achieve adaptive monitoring and detection of the target object, and collect more accurate second rear corner environmental information to assist the user in controlling the vehicle, ensuring the user's driving safety and experience.

[0051] S206. Receive the second rear corner environmental information collected by the rear corner detection device when it is in the preset detection mode, and display the corresponding display content of the second rear corner environmental information on the displayable screen.

[0052] Optionally, when the rear corner detection device is in a preset detection mode, it can detect the second rear corner environmental information in the vehicle's rear corner environment. After collecting the environmental information, the rear corner detection device will transmit the environmental information to the controller. The controller receives the second rear corner environmental information collected by the rear corner detection device in the preset detection mode and performs information analysis and preprocessing on the second rear corner environmental information to determine the display content corresponding to the second rear corner environmental information. For example, if there is a moving target, the corresponding pattern or animation of the moving target will be displayed. If there is a fixed obstacle, the corresponding icon and warning reminder of the fixed obstacle will be displayed. That is, after receiving the second rear corner environmental information, the display content corresponding to the second rear corner environmental information can be displayed on the display screen so that the user can know the current vehicle status through the display screen, which is convenient for the user to control the vehicle and drive.

[0053] This application provides an environmental information detection method. In response to a fault signal from an electronic rearview mirror system, the method determines the fault location corresponding to the fault signal, as well as the corresponding rear-angle detection device and display screen. Based on the first rear-angle environmental information collected by the rear-angle detection device, the method controls the rear-angle detection device to enter a preset detection mode. It receives the second rear-angle environmental information collected by the rear-angle detection device in the preset detection mode and displays the corresponding content on the display screen. Since the rear-angle detection device installed on the vehicle body can detect objects and their distances in the environment behind the vehicle, when a fault signal from the electronic rearview mirror system occurs, the rear-angle detection device corresponding to the fault location can be used to detect the environmental information behind the vehicle at the fault location. Furthermore, the rear-angle detection device can adaptively adjust itself to the preset detection mode based on the environmental information, thereby flexibly and accurately collecting the second rear-angle environmental information. The detected environmental information is then displayed on the available display screen. This allows for accurate display of the rear-angle environment to the user in rearview mirror fault scenarios, effectively assisting the user in safe vehicle control, improving the reliability and safety of the vehicle's rearview system, and ensuring user driving safety.

[0054] Please see Figure 4 , Figure 4 This is a flowchart illustrating an environmental information detection method provided in an embodiment of this application.

[0055] like Figure 4 As shown, environmental information detection methods can include at least:

[0056] S402. In response to the fault signal of the electronic exterior rearview mirror system, determine the fault location corresponding to the fault signal of the electronic exterior rearview mirror system and determine at least one rear corner detection device in the vehicle located on the same side as the fault location, and determine whether the electronic exterior rearview display screen on the same side corresponding to the fault location is operating normally. If the electronic exterior rearview display screen on the same side is operating normally, determine that the electronic exterior rearview display screen on the same side is a displayable screen.

[0057] Optionally, after the electronic exterior rearview mirror system malfunctions, the controller first receives a fault signal from the faulty component. In response to the fault signal, the controller determines the fault location and, based on that location, identifies the corresponding rear corner detection device and the display screen. As described in the above embodiments, the electronic exterior rearview mirror system fault signal is emitted by the faulty component. The controller records the location of each component in its information. Therefore, in response to the fault signal, the controller can simultaneously determine the fault location corresponding to the fault signal. Specifically, the component's location information refers to its position on the side of the vehicle, such as the left or right side.

[0058] Optionally, if there is a lack of rear view environment information on the side where the electronic exterior rearview mirror system fault signal occurs, then when using a rear corner detection device for auxiliary detection, the rear view environment information on the same side of the vehicle as the fault is required. That is, after determining the fault location corresponding to the electronic exterior rearview mirror system fault signal, at least one rear corner detection device on the same side of the vehicle as the fault location needs to be identified as the detection device for detecting rear corner environment information.

[0059] Optionally, when determining the displayable device, considering that the in-vehicle display screens include the electronic exterior rearview displays on both sides and the central control display screen, and that the electronic exterior rearview displays are usually only used to display the rear view on the corresponding side, while the central control display screen is used to display the in-vehicle terminal interface, in order to reduce the impact of the faulty side on the display of other display screens, it can be first determined whether the electronic exterior rearview display on the same side corresponding to the fault location is operating normally. If the electronic exterior rearview display on the same side is operating normally, for example, if the fault source of the electronic exterior rearview mirror system fault signal is a faulty electronic exterior rearview camera, it means that the electronic exterior rearview display and the electronic exterior rearview controller are intact at this time. That is, the electronic exterior rearview controller can normally receive signals and send them to the electronic exterior rearview display for display. At this time, it can be determined that the electronic exterior rearview display on the same side is a displayable screen.

[0060] S404. If the same-side electronic rearview display screen cannot operate normally, determine whether the non-same-side electronic rearview display screen corresponding to the fault location is operating normally.

[0061] Optionally, if the same-side electronic rearview display screen cannot operate normally, for example, if the fault source of the electronic rearview mirror system fault signal is a fault in the electronic rearview display screen, it means that the electronic rearview display screen cannot display normally at this time. Then it is necessary to further determine whether the non-same-side electronic rearview display screen corresponding to the fault location is operating normally, that is, to determine whether the non-same-side electronic rearview display screen corresponding to the fault location can be used as a display screen.

[0062] S406. If the non-same-side electronic rearview display screen is operating normally, then the non-same-side electronic rearview display screen is determined to be a displayable screen.

[0063] Optionally, if the non-same-side electronic rearview display screen is operating normally, it can be determined as a displayable screen. When using the non-same-side electronic rearview display screen to display the content corresponding to the second rear corner environmental information on the faulty side, specifically, a portion of the display area can be partitioned off from the non-same-side electronic rearview display screen to display the content of the faulty side without affecting the original display content on the non-same-side electronic rearview display screen. Alternatively, if the non-same-side electronic rearview display screen is not operating normally, it can be further determined whether the central control display screen is operating normally. If the central control display screen is operating normally, it can be directly used as a displayable screen, with a portion of its area partitioned off to display the content corresponding to the rear view environment.

[0064] S408. Control the rear corner detection device to be in close-range detection mode, and determine whether there is a target object in the rear corner environment based on the first rear corner environmental information collected by the rear corner detection device.

[0065] Optionally, as described in the above embodiments, the rear corner detection device can have an adaptive monitoring function. The adaptive monitoring function means that when the rear corner detection device collects the first rear corner environmental information, which may contain information about moving targets, the device can adaptively enter a preset detection mode based on this information.

[0066] Specifically, the rear corner detection device can be a millimeter-wave detection device, such as millimeter-wave radar. The millimeter-wave radar of a vehicle usually has several functions: (1) Collision avoidance function: The vehicle millimeter-wave radar can detect the distance and speed information of surrounding vehicles, pedestrians, obstacles and other objects to realize the collision avoidance function in the forward, backward and side directions. When the vehicle approaches other objects, the system will issue an alarm or automatically brake to avoid collision accidents; (2) Automatic parking function: When parking, the vehicle millimeter-wave radar can detect the distance and position information of surrounding objects to help the driver more accurately grasp the distance between the vehicle and the surrounding environment, thereby realizing the automatic parking function; (3) Blind spot monitoring function: The vehicle millimeter-wave radar can monitor the blind spot of the vehicle. When other vehicles or pedestrians enter the blind spot, the system will issue an alarm to remind the driver to pay attention; (4) Lane departure warning function: The vehicle millimeter-wave radar can monitor the driving trajectory of the vehicle. When the vehicle deviates from the lane, the system will issue an alarm to remind the driver to adjust the driving direction of the vehicle in time. Vehicle millimeter-wave radar can also be combined with other sensors, navigation systems and other technologies to achieve more intelligent driving assistance functions, such as adaptive cruise control, traffic sign recognition and intelligent speed limits.

[0067] Furthermore, the aforementioned functions of vehicle millimeter-wave detection equipment are mainly manifested in close-range and long-range detection of the vehicle's rear-view environment. Therefore, the two common detection modes of millimeter-wave detection equipment are close-range detection mode and long-range detection mode. The close-range detection mode is close-range wide-angle detection, that is, the detection distance is relatively short and the detection width is relatively wide. It is usually used when the vehicle is in reverse gear or reverse gear (R gear) to help the driver obtain information about objects in a wider range around the vehicle when reversing. The long-range detection mode is long-range narrow-angle detection, that is, the detection distance is relatively long and the detection width is relatively narrow. It is usually used when the vehicle is in drive gear (D gear) to help the driver obtain information about objects in a farther range behind the vehicle when driving.

[0068] Optionally, when a fault signal is generated in the electronic rearview mirror system and the rear corner detection device is required, the rear corner detection device can determine the detection mode it needs to switch to according to the specific information in the rear corner environment. In one feasible embodiment, when there is a target in the rear corner environment, more attention should be paid to whether there is a potential risk of the target being too close to the side of the vehicle within a relatively close and wide range of the rear corner of the vehicle. Therefore, a close-range detection mode with a wide angle of close range is more needed. Conversely, when there is no target in the rear corner environment, more attention should be paid to whether a target will appear within a relatively far range of the rear corner of the vehicle. Therefore, a long-range detection mode with a narrow angle of long range is more needed.

[0069] Therefore, it is understandable that, firstly, when a fault occurs, the rear corner detection device can be controlled to be in close-range detection mode to determine whether there are moving or fixed targets around the vehicle that threaten the vehicle's driving safety. Then, based on the first rear corner environmental information collected by the rear corner detection device, it can be determined whether there are targets in the rear corner environment, and based on the target situation in the first rear corner environmental information, it can be determined what detection mode needs to be used.

[0070] Please see Figure 5 , Figure 5This is a logical schematic diagram of an environmental information detection method provided in an embodiment of this application. Taking an electronic rearview mirror system that controls two electronic rearview cameras and two electronic rearview displays through an electronic rearview controller as an example, the electronic rearview controller in the electronic rearview mirror system sends the working status information of the electronic rearview mirror system to the rear corner radar controller of the rear corner detection module corresponding to the rear corner detection device. When a fault signal of the electronic rearview mirror system occurs, the rear corner radar controller determines the rear corner detection device that needs to be controlled through the fault signal of the electronic rearview mirror system in the working status information. By controlling the rear corner detection device to be in a preset detection mode based on the first rear corner environmental information, the second rear corner environmental information of the vehicle is detected and sent to the electronic rearview controller, so that the electronic rearview controller controls the display screen to display the display content corresponding to the second rear corner environmental information.

[0071] S410. If no target object exists, control the rear corner detection device to enter long-distance detection mode.

[0072] Optionally, as described in the above embodiments, the presence of a target object in the rear corner environment is determined based on the first rear corner environmental information collected by the rear corner detection device, and then the required detection mode for the rear corner detection device is determined based on the target object information. If no target object exists, the rear corner detection device needs to be controlled to be in a long-range detection mode to monitor whether there is a possibility of a target object appearing. Specifically, when the rear corner detection device is a millimeter-wave detection device, controlling the rear corner detection device to be in a long-range detection mode specifically involves adjusting the millimeter-wave detection device to a preset high frequency based on the frequency modulation chip (MMIC) so that the millimeter-wave detection device is in a long-range detection mode.

[0073] S412. If a target object is present, control the rear corner detection device to enter close-range detection mode.

[0074] Optionally, based on the first rear-angle environmental information collected by the rear-angle detection device, it is determined whether a target object exists in the rear-angle environment, and then the detection mode that the rear-angle detection device needs to be in is determined based on the target object information. If a target object exists, it is necessary to control the rear-angle detection device to be in a close-range detection mode to monitor whether there is a possibility of the target object appearing. Specifically, when the rear-angle detection device is a millimeter-wave detection device, controlling the rear-angle detection device to be in a close-range detection mode specifically involves adjusting the millimeter-wave detection device to a preset low frequency based on the frequency modulation chip (MMIC) so that the millimeter-wave detection device is in a close-range detection mode.

[0075] S414. Receive the second rear corner environmental information collected by the rear corner detection device when it is in the preset detection mode, and display the corresponding display content of the second rear corner environmental information on the displayable screen.

[0076] For details regarding step S414, please refer to the description in step S206; it will not be repeated here.

[0077] This application provides an environmental information detection method. First, based on the relationship and operating status of multiple in-vehicle display screens with the fault location, a suitable normally operating display screen is selected as the displayable screen while minimizing the impact on other normally displayed content. When the rear corner detection device is a millimeter-wave detection device, it can have an adaptive monitoring function. The rear corner detection device is controlled to be in a close-range detection mode. Based on the first rear corner environmental information collected by the rear corner detection device, it is determined whether there is a target object in the rear corner environment. If there is no target object, the rear corner detection device is controlled to be in a long-range detection mode to monitor whether a target object will appear. If a target object exists, the rear corner detection device is controlled to be in a close-range detection mode to reduce the hidden danger of the target object being too close to the side of the vehicle. This provides the user with an accurate view of the rear corner environment, effectively assisting the user in safe vehicle control, improving the reliability and safety of the vehicle's rearview system, and ensuring the user's driving safety.

[0078] Please see Figure 6 , Figure 6 This is a flowchart illustrating an environmental information detection method provided in an embodiment of this application.

[0083] Optionally, since a malfunction in the electronic exterior rearview mirror system can result in a loss of information about the vehicle's rear corner environment, potentially jeopardizing lane-changing safety, a warning or alert should be issued to the user if they wish to change lanes when the rearview mirror system malfunctions. This means that the system first determines the potential lane-changing risk by using vehicle control signals triggered by the vehicle control devices, such as turn signals, steering wheel, and headlight stalks. Please refer to [link to relevant documentation]. Figure 5 Specifically, the rear corner radar controller of the rear corner detection module can receive the vehicle control signal triggered by the vehicle control device and send it to the controller for judgment.

[0084] S606. If there is a risk of lane change, the lane change alarm content will be displayed on the display screen, and a lane change alarm prompt will be issued.

[0085] Optionally, when a user operates the vehicle control device, if a lane change risk is detected based on the vehicle control signal triggered by the device, a lane change alarm message is displayed on the screen, and a lane change alarm notification is issued. Specifically, the lane change alarm message may be an animation, pattern, etc., related to the lane change action, and the lane change alarm notification may be an alarm ringtone, voice broadcast, etc., which are not limited in this embodiment.

[0089] Optionally, the second rear-angle environmental information collected by the rear-angle detection device when it is in a preset detection mode includes the target objects in the rear-angle environment and the distance between the target objects and the vehicle. Furthermore, when the rear-angle detection device is a millimeter-wave detection device, it can identify the type of target objects in the rear-angle environment, such as pedestrians, vehicles, bicycles, roadblocks, etc. Since the display device has been determined through the aforementioned steps, the display content can be further determined based on the target objects and distances. The content can be animations, patterns, etc., corresponding to the type of target objects, so that users can more clearly know the objects behind the vehicle and predict their speed and direction of movement, making it easier for users to control the vehicle more safely.

[0090] S612. Display the content on the displayable screen.

[0091] Optionally, after determining the display content, the display content shows the information of the target object and the distance information of the target object through patterns, animations, prompt sound effects, etc. At this time, the corresponding display content is displayed on the displayable screen, so that the user can observe the rear corner environment information of the vehicle through the displayable screen, so that the user can know the current vehicle status through the display screen, which is convenient for the user to control the vehicle and drive.

[0092] In this embodiment, an environmental information detection method is provided. In response to a fault signal from an electronic rearview mirror system, the method determines the fault location corresponding to the fault signal, as well as the corresponding rear corner detection device and display screen. Based on a vehicle control signal triggered by a vehicle control device, it determines whether there is a lane change risk. The vehicle control device includes at least one of a steering lever, a steering wheel, and a headlight lever. If a lane change risk exists, a lane change warning is displayed on the display screen, and a lane change warning prompt is issued. Based on first rear corner environmental information collected by the rear corner detection device, the method controls the rear corner detection device to be in a preset detection mode. It receives second rear corner environmental information collected when the rear corner detection device is in the preset detection mode, identifies targets in the rear corner environment and the distance between the targets and the vehicle based on the second rear corner environmental information, determines display content based on the targets and distance, and displays the display content on the display screen. This allows for timely warnings about lane-changing safety when a user shows a tendency to change lanes, protecting the user's safety and reliability during lane changes. The displayed information about the target object includes its type and distance from the vehicle, enabling the user to clearly understand objects behind the vehicle and predict their speed and direction, thus facilitating safer vehicle control.

If the electronic exterior rearview display screen on the same side is operating normally, then the electronic exterior rearview display screen on the same side is determined to be a displayable screen. If the electronic exterior rearview display screen on the same side is not operating normally, then the module determines whether the electronic exterior rearview display screen on the opposite side corresponding to the fault location is operating normally. If the electronic exterior rearview display screen on the opposite side is operating normally, then the electronic exterior rearview display screen on the opposite side is determined to be a displayable screen.

Since the rear corner detection device installed on the vehicle body can detect objects and their distances in the environment behind the vehicle, when a fault signal occurs in the electronic exterior rearview mirror system, the rear corner detection device corresponding to the fault location can be used to detect the environmental information behind the vehicle at that location. Furthermore, the rear corner detection device can adaptively adjust itself to a preset detection mode based on the environmental information, thereby flexibly and accurately collecting second rear corner environmental information. The detected environmental information is then displayed on an available display screen.
