Detailed Implementation

[0018] 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.

[0019] The following description, with reference to the accompanying drawings, describes a vehicle guard mode control method according to an embodiment of this application. Addressing the issues mentioned in the background section regarding the current automotive third-space mode, which still falls short in meeting the safety, experience, and personalization needs of certain users, such as women, this application provides a vehicle guard mode control method.

[0020] Figure 1 This is a flowchart illustrating a vehicle guard mode control method provided in an embodiment of this application.

[0021] like Figure 1 As shown, the guard mode control method for this vehicle includes the following steps: In step S101, in response to the vehicle's guard mode activation command, the vehicle's voiceprint recognition module is activated. The voiceprint recognition module is used to control the vehicle's language recognition function to recognize the voice information issued by the corresponding user in the preset voiceprint list.

[0022] The voiceprint recognition module is an integrated hardware and software unit built into the vehicle, which may include: a microphone unit, a voiceprint feature extraction algorithm, a local storage unit, and voice permission verification logic. In normal driving or short rest mode, the module can go into sleep mode with low power consumption. Once it receives the command to activate the guard mode, the system wakes up, powers on, loads voiceprint data, and enters the real-time authentication working state. The guard mode is a high-security scenario, and the vehicle cannot be controlled by voice by just anyone. Voiceprint must be used for identity isolation.

[0023] Regarding the guard mode activation command, in one embodiment of this application, it includes: in response to the vehicle receiving a target command sent by the user, generating a guard mode activation inquiry message and providing the guard mode activation inquiry message to the user; in response to the feedback result corresponding to the received guard mode activation inquiry message being a confirmation activation command, generating a guard mode activation command.

[0024] In this embodiment, the target instruction specifically refers to the user's operation instruction to trigger the in-vehicle nap function or the in-vehicle audio-visual entertainment function. For example, three triggering methods can be set: clicking the vehicle screen, voice wake-up, and starting a timed nap alarm. The vehicle's central controller can monitor the vehicle's interaction instructions in real time. Once it recognizes that the user has initiated the nap or entertainment function, it immediately executes the subsequent pop-up query logic to generate a query message asking whether the guard mode is enabled. This query message can include two types of expanded forms: 1) Visual information (in-vehicle screen pop-up): The text prompts "Do you want to turn on the guard mode? After turning it on, it will monitor the surroundings in real time and ensure the safety of resting in the car." It is accompanied by two interactive buttons: turn on and turn off. At the same time, it displays a brief introduction to the core functions of the guard mode (such as 360-degree all-round camera monitoring, graded sound and light warnings, one-click alarm, etc.). 2) Voice inquiry: The car's infotainment system will announce, "We have detected that you have activated the nap mode. Do you wish to activate the guard mode?" This set of pop-up window and voice prompts is collectively referred to as the "Guard Mode Activation Inquiry". After the user sees or hears the inquiry, they will give feedback. The system collects the feedback signal, and when it recognizes that the user has confirmed activation, the vehicle's internal system generates a standardized Guard Mode Activation command that can be sent to all hardware modules of the vehicle. This command is the overall trigger signal for the vehicle's safety protection logic.

[0025] In one embodiment of this application, after responding to the vehicle's guard mode activation command, the method further includes: determining whether the preset voiceprint list is empty; if the preset voiceprint list is empty, then activating the vehicle's voiceprint recording function; and storing the user's voiceprint information obtained through the voiceprint recording function in the preset voiceprint list.

[0026] Upon receiving the command to activate the guard mode, the vehicle wakes up the voiceprint recognition module and then performs this judgment. This is a pre-verification step in the guard mode initialization. The preset voiceprint list, also known as the voiceprint whitelist, can be encrypted and stored locally in the vehicle's infotainment system. It stores the voiceprint feature templates of registered vehicle owners and is the sole basis for voice authentication in the guard mode. The voiceprint module reads the local storage area to check if any valid voiceprint data exists in the list. If the list is not empty: If the owner's voiceprint is already present, proceed directly to the real-time voice collection and identity comparison logic. The list is empty: The user has never registered a voiceprint and is a first-time user. Voice permission control cannot be performed, so the registration process will begin.

[0027] This voiceprint recognition mechanism automatically detects the voiceprint list when the guard mode is activated. If no voiceprint is stored, it guides the user to register and save it on-site. On the one hand, it eliminates the need for users to manually register in the settings interface in advance, improving ease of use. On the other hand, it establishes a whitelist of voice permissions for car owners, blocking voice commands from strangers and preventing criminals from using voice to turn off the alarm or unlock the car door. This fills the security loophole of voice control in the guard mode. It relies on the original car voice hardware to achieve identity authentication without adding additional hardware costs, ensuring operational security in the car resting scenario.

[0028] In one embodiment of this application, in response to the vehicle's guard mode activation command, the method further includes: displaying relevant information about the vehicle entering guard mode on an external screen above the vehicle's exterior hood.

[0029] After voiceprint recognition and recording are completed, the vehicle controller can immediately send a display command to the external screen, activating simultaneously with the in-vehicle security function. This screen is existing vehicle hardware, requiring no additional equipment. It faces pedestrians and people approaching the vehicle, serving as a visual interaction channel, unlike the central control screen which is only visible inside the vehicle. For example, the screen can be set to display fixed text: "In security mode, the vehicle will continuously monitor the surrounding environment to clearly inform external personnel that the vehicle is monitoring the surroundings in real time and has security alarm capabilities."

[0030] In step S102, the environment around the vehicle is monitored to obtain environmental monitoring information of the vehicle.

[0031] This step is the environmental monitoring procedure after the guard mode is activated. After the guard mode activation command takes effect, the vehicle continuously conducts real-time monitoring of the entire area around the vehicle, collects and generates environmental monitoring information around the vehicle, and provides data basis for subsequent abnormal information such as graded warnings, illegal door opening judgment, and hijacking identification.

[0032] For example, the vehicle's 360-degree external surround view camera can be used as the core data collection device to monitor and cover the area within 1 meter around the vehicle, focusing on identifying targets such as pedestrians and hands pulling on the car door, continuously collecting images and distance data throughout the process, and outputting environmental monitoring information in real time.

[0033] Environmental monitoring information may include, but is not limited to: Pedestrian distance information: Calculates the real-time distance between pedestrians and the vehicle, distinguishing between two threshold levels: 1m and 0.5m; Human presence information: Whether people appear in the image and their movement trajectory; Door handle action information: Identify the frequency of repeated door handle pulls by external personnel; Real-time video feed: Panoramic view of the vehicle exterior, simultaneously saved for uploading to the backend when a one-click alarm is triggered.

[0034] In step S103, the environmental monitoring information is analyzed and identified to obtain abnormal information around the vehicle, and in step S104, the vehicle is controlled according to the abnormal information.

[0035] These two steps build upon the environmental monitoring information collected in the previous step and consist of two core components: first, analyzing and identifying the monitoring data to extract various abnormal information around the vehicle; and second, based on the identified different types of abnormalities, controlling the vehicle's sound and light, door locks, external screens, driver assistance, alarms, and other equipment to perform different protective actions, forming an automated safety closed loop of perception, judgment, and response.

[0036] In actual operation, the vehicle system can receive raw environmental monitoring data such as images from 360-degree surround view cameras, pedestrian distance measurement, and door handle movements. It then analyzes and processes the data using in-vehicle image recognition algorithms, distance threshold logic, and behavior statistics rules to extract key features such as the distance between pedestrians and the vehicle, pedestrian approach trajectories, and door handle pulling frequency. By comparing these features with preset safety judgment standards, the system distinguishes between ordinary pedestrians and risky behaviors and ultimately outputs different levels of surrounding anomaly information, providing a basis for the vehicle to implement graded warnings and alarm control.

[0037] To clearly illustrate the previous embodiment, in one embodiment of this application, the abnormal information includes a person entering within a preset distance of the vehicle. The method of controlling the vehicle based on the abnormal information includes: obtaining the distance between the person and the vehicle, generating a voice control command for the vehicle based on the distance, and controlling the vehicle based on the voice control command.

[0038] This embodiment defines one type of abnormal information: pedestrians entering the vehicle's preset warning distance range; upon identifying this abnormality, the system can calculate the distance between the person and the vehicle in real time. For example, based on a 360-degree surround-view visual ranging algorithm, it can calculate the precise distance from the pedestrian to the vehicle in real time and continuously update the distance value as the core parameter for distinguishing warning levels. Then, based on the distance, it generates corresponding sound control commands and sends commands to drive the vehicle's external speakers to emit graded warning sound effects, thereby achieving tiered external deterrence.

[0039] The preset distance can be set to two threshold levels: 1 meter and 0.5 meters. As long as the camera detects a pedestrian entering the 1-meter warning range, it will determine that an abnormal information such as "person approaching" is generated, triggering the subsequent sound level reminder logic, controlling the external speakers to emit a "cough cough" warning sound, and emitting a "cough cough" warning sound again when the distance is 0.5 meters.

[0040] In one embodiment of this application, the abnormal information includes unauthorized door opening behavior, wherein controlling the vehicle based on the abnormal information includes: controlling the vehicle to simulate engine roaring, flashing lights and sounding the horn alarm until a cancellation command is received from the user.

[0041] This embodiment designs a dedicated handling logic for the high-risk abnormal information of unauthorized door opening: After the system identifies that an external person has repeatedly pulled on the car door handle for unauthorized intrusion, if the door handle is pulled open more than twice, it can be regarded as unauthorized door opening, and multiple sound and light linkage alarms are triggered simultaneously, such as activating the simulated engine roar sound + flashing of all lights such as high beams + honking alarm, to continuously deter and drive away suspicious persons. The entire alarm action will not stop automatically. The alarm action will only end after the system detects the user's voiceprint, actively cancels the alarm, and receives confirmation.

[0042] The alarm can be deactivated in two ways: either by issuing a voice command and passing the voiceprint verification, or by manually clicking the deactivation button on the central control screen. The alarm cannot be deactivated by voice or operation from strangers, thus preventing criminals from deliberately terminating the protection.

[0043] Upon detecting unauthorized door opening, the system triggers multiple high-intensity alarms, including simulated engine sounds, flashing lights, and horn blaring, providing a stronger deterrent effect. The alarms can only be deactivated by the vehicle owner via voiceprint or screen operation, preventing unauthorized personnel from maliciously closing the protection and effectively resisting malicious door-pulling intrusion, significantly enhancing personal safety in situations where individuals are alone and resting in the vehicle.

[0044] In one embodiment of this application, the abnormal information includes a vehicle user being hijacked. Controlling the vehicle based on the abnormal information includes: controlling the vehicle to activate the assisted driving automatic following function and maintaining a preset distance from the user, as well as controlling the vehicle to emit a warning sound, while sending environmental monitoring information to the target platform and performing an automatic alarm operation until a cancellation command is received from the user.

[0045] This embodiment can be designed with exclusive handling logic for the extremely dangerous scenario of user hijacking: after the system identifies hijacking-related abnormal information, it automatically starts the assisted driving automatic following, maintains a fixed safe distance, and plays warning sounds in a loop. At the same time, it uploads the surrounding monitoring video to the car manufacturer's backend and triggers an alarm. The entire protection process is in effect and can only be terminated by the car owner issuing a cancellation command.

[0046] Specifically, the system can determine that the vehicle owner is in a high-risk hijacking situation by combining signals such as in-vehicle voiceprints, in-vehicle images, and external coercion, generate hijacking-related abnormal information, and trigger the highest level of emergency protection. Emergency protection may include: 1. The vehicle starts the assisted following logic, continuously maintaining a preset safe distance of 1 meter from the target vehicle to prevent the driver from being taken to a remote and deserted area, providing conditions for the background and the police to track and locate the vehicle.

[0047] 2. The vehicle plays a warning voice message every 3 seconds to inform the outside world that the video has been uploaded and the vehicle can be located and an alarm has been triggered; at the same time, the environmental monitoring images and vehicle location collected by the 360 ​​camera are uploaded to the car manufacturer's headquarters server (target platform), and the background alarm process is initiated simultaneously to retain complete audio-visual evidence.

[0048] The warning sound can be set to "Relevant video has been uploaded to the car headquarters. If there is a dangerous situation, an alarm will be triggered based on the vehicle's location," and the text will be displayed simultaneously on the external screen above the hood.

[0049] The hijacking warning, following vehicle, voice alert, and background alarm will not stop automatically. The entire set of emergency actions will only be deactivated after the car owner, whose voiceprint has been verified, has safely entered the vehicle and manually / voicely issues a cancellation command. This is to prevent hijackers from shutting down the protective measures and destroying evidence. Alternatively, the user can issue the command via a mobile phone that is already connected to the in-vehicle internet.

[0050] In one embodiment of this application, it further includes: in response to receiving a user alarm command, controlling the vehicle door locks, transmitting video data inside and outside the vehicle to the vehicle headquarters server and directly connecting to the alarm, while retaining the four door lock buttons, one-button alarm button, voiceprint recognition button, and audio sound mode and volume adjustment functions inside the vehicle.

[0051] When a user actively triggers a one-click alarm command, the vehicle simultaneously performs three emergency protection actions: locking the doors, transmitting video, and linking to the police alarm. At the same time, all safety operation controls in the central control room are retained, allowing the owner to still independently control the vehicle door locks, alarm volume, and voiceprint permissions in dangerous scenarios, thus balancing safety and autonomy of in-vehicle operation.

[0052] The alarm command originates from the one-button alarm on the vehicle's infotainment screen. This is the highest-level emergency operation initiated by the user, triggering a complete emergency response process. The system immediately locks all four doors and the trunk, completely isolating the entry points for external personnel and preventing criminals from forcibly entering the cabin, thus physically protecting the occupants. The vehicle can retrieve real-time interior and exterior images and historical recordings from the previous 10 minutes, encrypting and uploading them to the automaker's backend server for evidence storage. Simultaneously, a dedicated line can be established to directly connect to the 110 emergency hotline, and vehicle location and surveillance video can be uploaded synchronously, providing complete evidence for police investigation. Furthermore, even with the entire vehicle locked and alarm activated, the central control interface does not lock all functions, allowing for continued access to the following: individual door lock / unlock buttons, the one-button alarm, the voiceprint recognition start / stop button, switching between interior and exterior audio modes, and volume adjustment. The owner can adjust the alarm loudness, individually lock / unlock doors, trigger a secondary alarm at any time, and switch voiceprint authentication status as needed.

[0053] After a one-click alarm is triggered, the doors automatically lock to prevent external intrusion, and simultaneously upload video footage and connect directly to the police to form a complete emergency evidence collection alarm link. At the same time, it does not restrict the owner's central control operation permissions, which can maximize the isolation of external dangers and retain complete accident evidence, while also allowing the owner to flexibly adjust the sound and light alarms, control the door locks and identity verification functions. In extremely dangerous scenarios, it balances the strength of protection and the freedom of operation inside the car, comprehensively improving the self-rescue protection for women who are alone in the car and encounter danger.

[0054] Furthermore, this embodiment of the application can also be set to automatically pop up a guard (bodyguard) mode pop-up window when the user's preset alarm rings, supporting one-click access to the dedicated bodyguard mode operation interface without multiple menu jumps, making the operation path simple. The interface can simultaneously retrieve real-time images from the vehicle's 360-degree external camera, intuitively displaying the vehicle's surrounding environment; the system automatically identifies whether there are pedestrians in the image and provides text / voice prompts to inform the user whether there are any suspicious persons within the monitoring range. The purpose of this design is to allow users to see the situation outside the car in advance through the camera before getting out of the car after waking up, avoiding the risks of people lurking or following in the dark of the parking lot, and giving women alone time to anticipate the external environment.

[0055] In one embodiment of this application, the method further includes: in response to a vehicle's guard mode off command, turning off the voiceprint recognition module and the external screen above the front hood; wherein, in response to detecting that the vehicle alarm is turned on, generating a guard mode off inquiry message and providing the guard mode off inquiry message and environmental monitoring information to the user; in response to the feedback result corresponding to the received guard mode off inquiry message being a confirmation off command, generating a guard mode off command.

[0056] This embodiment defines the entire process of exiting the guard mode, such as... Figure 2 As shown, the entire process of exiting Guard Mode can be summarized into two main steps: the prompt to close and the action of shutting down Guard Mode. Disable the trigger inquiry process: When the alarm rings after the user finishes their nap, or when the user actively taps the car's infotainment system to turn off the guard mode, the system initiates a dual verification: First, verify the voiceprint of the person who initiated the shutdown request via voice: Voiceprint mismatch (N): Ignore the shutdown request and continue running in guard mode; Voiceprint matching for car owner (Y): A pop-up window will appear to confirm whether the user is sure they want to turn off the guard mode.

[0057] User confirmation branch: User selects not to close (N): Returns to the parallel monitoring link, and the guard mode remains on; User confirms shutdown (Y): Generates a guard mode shutdown command and executes the exit operation.

[0058] Guard Mode shutdown process: Upon receiving confirmation of the shutdown command, two shutdown processes will be completed simultaneously: The external display screen on the front hood is off. The in-vehicle voiceprint recognition module issues a command and shuts down its sleep mode; the entire guard mode process is now complete.

[0059] In summary, this application's embodiment, through its guard mode design, addresses the psychological and physiological needs of users experiencing insecurity during naps or in-car entertainment. Leveraging the high integration of hardware and software such as car cameras, audio systems, horns, and in-vehicle interaction systems, it interacts with both inside and outside the vehicle, providing users with a solution to enhance their sense of security in scenarios such as fear of unauthorized access, malicious door opening, or hijacking in parking lots. This transforms the car from a mere means of transportation into a partner and a guardian. The advantages of this solution can be summarized as follows: 1) Experience Advantages: Improvements are made to address the high-frequency pain points of the mainstream car-using groups, such as women or those taking a nap in the car, and provide users with a sense of security and trust. Furthermore, the multi-modal and integrated advantages of automobiles are used to provide users with multi-dimensional and multi-channel solutions.

[0060] 2) Cost advantage: Without the need for large-scale R&D of new products or large-scale experimental verification, the technology achieves the effect of improving the user experience through the multimodal combination and design of existing technologies.

[0061] Furthermore, such as Figure 3 As shown, Figure 3 This is a prototype layout of the central control interface for the Guardian Mode (Bodyguard Mode), divided into two main areas: a top explanatory control area and a lower multi-functional operation area. The functions of each module are as follows: I. Top area: The text description box in the upper left corner explains the core mechanism of the bodyguard mode: After this mode is activated, the vehicle can continuously use external cameras to identify whether anyone is approaching, thereby protecting the safety of the cabin and passengers. This provides a clear explanation of the mode's function to the user.

[0062] Top right corner: Bodyguard mode switch is the master control for the mode, used to turn the entire bodyguard security protection function on and off with one click. It is the main entry point for entering / exiting guard mode.

[0063] II. Bottom Function Operation Area (6 function windows in total): The largest window on the left displays real-time footage from the external 360-degree cameras, showing the outside view captured by the cameras around the vehicle. Users can intuitively view the surrounding people and environment and anticipate external risks in advance.

[0064] The first control at the top center: "Approaching Person Alarm Sound Adjustment" is used to adjust the volume of the first and second level warning sound effects when a pedestrian approaches a vehicle. Users can control the intensity of the close-range alert sound.

[0065] The second control at the top center: One-click lock all doors (including the four doors and the trunk) is an emergency locking control. Clicking it will lock all four doors and the trunk at once, physically preventing outsiders from opening the doors and intruding.

[0066] The first control at the bottom center: "Illegal Door Opening Scene Sound Adjustment" can be used to adjust the volume of the simulated high-intensity alarm sound when malicious door pulling or illegal door opening is detected, allowing for customized deterrent sound effects for high-risk scenarios.

[0067] The second control at the bottom center: External speaker volume adjustment. This control allows you to uniformly control the base volume of the vehicle's external speakers and adjust the alarm volume to suit different parking lots, nighttime, and other scenarios.

[0068] The large window on the far right: The one-click alarm can be used as the highest level emergency function button. After clicking to trigger it, the car manufacturer's backend (such as Jihu) will directly connect with the police, simultaneously upload vehicle video and location, and assist in handling dangerous situations.

[0069] The entire interface integrates real-time external visual monitoring, multi-level alarm volume customization, full vehicle door lock control, and emergency alarm functions into a single page. Users do not need to switch between multiple menus; they can complete all security operations, including environmental viewing, protective sound effect settings, physical vehicle locking, and one-click alarm, all within the bodyguard mode interface. The interaction is centralized and simple, making it suitable for quickly and autonomously handling various external risks when resting alone in the car.

[0070] According to the vehicle guard mode control method proposed in this application, after the guard mode is activated, the voiceprint recognition module can be started simultaneously to verify the owner's identity by using voice commands. At the same time, the monitoring information of the vehicle's surrounding environment is continuously collected and analyzed to identify various external anomalies. Then, based on the different levels of anomalies, the vehicle's sound and light, driving assistance, alarm and other hardware are linked to perform corresponding protective measures. This not only prevents outsiders from maliciously manipulating security functions through voiceprint authentication, but also achieves automatic risk identification and layered active protection by relying on full-domain environmental perception, thereby greatly improving the security of the in-vehicle resting scenario.
