Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, device, equipment, and storage medium for reminding users when they have forgotten their mobile phones. Background Technology

[0002] With the rapid development of automotive intelligence and connectivity technologies, digital car keys have gradually replaced traditional physical keys. Users can conveniently unlock and start their vehicles through smart terminals (such as mobile phones), significantly improving the user experience.

[0003] However, users often forget their phones in their cars, and then search for them everywhere when they get home. This not only wastes time and energy, but may also affect subsequent communication and travel arrangements because they cannot retrieve their phones in time, causing trouble and inconvenience to users. Summary of the Invention

[0004] This application provides a method, device, equipment, and storage medium for reminding users when they forget their mobile phone, which can help users quickly find out the location of their mobile phone and improve the effectiveness of the reminder and the user experience.

[0005] One aspect of this application provides a method for reminding users to leave their phones behind, the method comprising: The Bluetooth signal of a mobile phone inside the target vehicle is detected by the multi-antenna Bluetooth detection unit of the target vehicle, and the mobile phone is determined to be left inside the target vehicle based on the Bluetooth signal. The operating status of the target vehicle is detected; wherein the categories of the operating status include the engine off and locked status; The system uses multi-sensor fusion at the smart home terminal to determine whether the driver and passengers of the target vehicle have returned home, generates a corresponding home return status signal, and sends the home return status signal to the target vehicle through an encrypted communication link. When the control unit of the target vehicle simultaneously determines that the mobile phone is inside the target vehicle, the target vehicle is in a locked and turned-off state, and the home status signal indicates that the driver and passengers have returned home, a reminder command is generated for the mobile phone. The target vehicle is controlled to send the reminder command to the smart home terminal through the encrypted communication link, thereby triggering the smart home terminal to execute a preset reminder operation.

[0006] Exemplarily, in some embodiments, the method further includes: The system receives the communication address and device model of the smart home terminal input by the user through the central control touch screen of the target vehicle or the terminal software of the target vehicle, and records the communication address and device model into the storage unit of the target vehicle. The user's identity information and the Bluetooth identifier of the mobile phone used by the user are recorded into the storage unit; Based on the communication address of the smart home device, the encrypted communication link is established, and the encryption key of the encrypted communication link is synchronized to the smart home device.

[0007] Exemplarily, in some embodiments, the method further includes: The system receives user-defined settings on the terminal software; wherein the settings are used to indicate the content of the reminder instruction, the number of times to repeat the reminder, and the interval between repeat reminders.

[0008] For example, in some embodiments, determining whether the mobile phone is inside the target vehicle based on the mobile phone's Bluetooth signal includes: Detect whether the Bluetooth signal of the mobile phone matches the Bluetooth identifier of the pre-recorded mobile phone; When it is determined that the mobile phone Bluetooth signal and the Bluetooth identifier match, and the strength of the mobile phone Bluetooth signal is continuously greater than a preset threshold for more than a first duration, it is determined that the mobile phone is left inside the target vehicle, and the identity information of the driver and passenger corresponding to the left-behind mobile phone is determined according to the Bluetooth identifier.

[0009] For example, in some embodiments, determining whether the occupants of the target vehicle have returned home through multi-sensor fusion at the smart home terminal includes: Based on the identity information of the driver and passengers corresponding to the detained mobile phones, the target personnel to be identified are determined; The status of the door lock is detected through the smart home terminal; If the state of the door lock changes, the smart home terminal detects whether the target person exists in the surrounding area. If the target person exists, determine that the driver and passengers of the target vehicle have returned home.

[0010] For example, in some embodiments, sending the reminder instruction to the smart home device to trigger the smart home device to perform a preset reminder operation includes: Send the reminder command to the smart home terminal; The current ambient noise is detected through the smart home terminal; The broadcast volume is determined based on the ambient noise, and a reminder operation is performed based on the reminder instruction and the broadcast volume.

[0011] For example, in some embodiments, the reminder operation based on the reminder instruction and the broadcast volume includes: According to the reminder instruction, perform a reminder operation according to the broadcast volume; The smart home device detects whether the driver or passenger provides any feedback or response. If the driver or passenger does not provide feedback, after waiting for a preset interval, the step of performing a reminder operation according to the reminder instruction and the broadcast volume is repeated until the driver or passenger provides feedback or the preset number of repeated reminders is reached.

[0012] On the other hand, embodiments of this application provide a reminder device for forgetting a mobile phone, the device comprising: The first determination unit is used to detect the mobile phone Bluetooth signal inside the target vehicle through the multi-antenna Bluetooth detection unit of the target vehicle, and determine whether the mobile phone is left inside the target vehicle based on the mobile phone Bluetooth signal. A detection unit is used to detect the operating status of the target vehicle; wherein the categories of the operating status include the engine off and locked state; The second determination unit is used to determine whether the driver and passengers of the target vehicle have returned home through multi-sensor fusion of the smart home terminal, generate a corresponding home return status signal, and send the home return status signal to the target vehicle through an encrypted communication link. The generation unit is used to generate a reminder command for the mobile phone when the control unit of the target vehicle simultaneously determines that the mobile phone is left inside the target vehicle, the target vehicle is in a locked and turned-off state, and the home status signal indicates that the driver and passenger have returned home. An execution unit is used to control the target vehicle to send the reminder instruction to the smart home terminal through the encrypted communication link, so as to trigger the smart home terminal to execute a preset reminder operation.

[0013] On the other hand, embodiments of this application provide an electronic device, including a processor and a memory; The memory is used to store computer programs; The processor executes the computer program to implement the aforementioned method for reminding users when they have forgotten their mobile phone.

[0014] On the other hand, embodiments of this application provide a computer-readable storage medium storing a computer program, which is executed by a processor to implement the aforementioned method for reminding users when they have forgotten their mobile phones.

[0015] On the other hand, embodiments of this application also provide a computer program product, which includes a computer program stored in a computer-readable storage medium. The processor of a computer device reads the computer program from the computer-readable storage medium and executes the computer program, causing the computer device to perform the aforementioned method for reminding users to forget their mobile phones.

[0016] This application provides a method, apparatus, device, and storage medium for reminding users when their mobile phones are forgotten. By linking the vehicle and smart home terminals, this application improves the effectiveness of reminding users when their phones are left in a vehicle. The target vehicle uses a multi-antenna Bluetooth detection unit to detect the Bluetooth signal of the mobile phone inside the vehicle to determine whether the phone is left inside and whether the vehicle is locked and turned off. Simultaneously, the smart home terminal uses multi-sensor fusion to determine whether the occupants have returned home and sends this home status signal to the target vehicle via an encrypted communication link. After simultaneously confirming that the phone is left inside the vehicle, the vehicle is locked and turned off, and the occupants have returned home, the control unit of the target vehicle generates a reminder command and sends it to the smart home terminal via an encrypted communication link, thereby triggering the execution of a preset reminder operation. This application achieves the accuracy of reminder timing through cross-scenario (vehicle and home) collaborative perception and decision-making; at the same time, by utilizing reminder methods in a home environment, it ensures that the reminder can be reliably perceived by the user, allowing the user to quickly know the location of the phone, thus improving the effectiveness of the reminder and the user experience.

This application achieves the accuracy of reminder timing through cross-scenario (vehicle and home) collaborative perception and decision-making; at the same time, by utilizing reminder methods in a home environment, it ensures that the reminder can be reliably perceived by the user, allowing the user to quickly know the location of the mobile phone, thus improving the effectiveness of the reminder and the user experience.

[0025] System architecture and scenario description used in the embodiments of this application Please refer to Figure 1 , Figure 1 The diagram shows a system architecture diagram of a mobile phone forgetting reminder method provided in this application embodiment, which includes a smart home terminal 150, a vehicle terminal 140, an Internet 130, a gateway 120, a backend server 110, etc.

[0026] In this embodiment, the smart home terminal 150 can be a smart control hub device deployed in the user's living environment. It may include a multi-sensor fusion sensing module, an environmental status analysis unit, an intelligent decision-making module, and a home device linkage control module. The smart home terminal 150 can connect to home devices such as indoor positioning base stations, environmental sensor arrays, smart speakers, and smart displays via a local area network or wireless communication protocol to collect and process in real time human activity signals, environmental noise data, and device status information within the home area. Simultaneously, the smart home terminal 150 can interact with the backend server 110 (and the vehicle terminal 140) via a gateway 120 and the Internet 130 to synchronize the vehicle's ignition status, in-vehicle Bluetooth detection results, and reminder commands, ensuring that reminder operations are executed in the home environment at the most appropriate time. This application does not impose any limitations on this aspect.

[0027] Vehicle-side 140 refers to the onboard computing and communication control unit integrated in the target vehicle, which may include a multi-antenna Bluetooth detection engine, a vehicle operating status monitoring module, an encrypted communication interface, and an intelligent decision-making unit. Vehicle-side 140 can connect to in-vehicle hardware such as the Bluetooth antenna array, ignition switch status sensor, and door lock sensor via the vehicle bus or local wireless communication link to detect and determine in real time whether a mobile phone is left inside the vehicle and whether the vehicle is in a locked, off-road state. Simultaneously, vehicle-side 140 can establish an encrypted communication link with smart home terminal 150 via Internet 130 to send requests for home arrival status signals and receive feedback on the execution of reminder commands, achieving cross-scenario collaborative reminders. This application does not impose any limitations on this aspect.

[0028] Internet 130 refers to public or private communication infrastructure that provides network connectivity and data transmission services, enabling remote data communication between vehicle terminal 140 and smart home terminal 150, and supporting the stable operation of encrypted communication protocols. This application does not impose any restrictions on this.

[0029] The backend server 110 refers to a computer system that provides data support and collaborative services to the vehicle terminal 140 and the smart home terminal 150. Compared to the terminal devices, the backend server 110 has higher requirements in terms of data processing capabilities, concurrent capacity, system stability, and network security. The backend server 110 can be a high-performance physical server in a cloud platform, a cluster of multiple servers, a virtual machine instance in a virtualization environment, or a comprehensive cloud service node that includes capabilities such as cloud storage, cloud computing, big data analysis, and artificial intelligence algorithm services. This application does not impose any restrictions on this.

[0030] The mobile phone forgetting reminder method provided in this application embodiment can be executed by the vehicle terminal 140, generating a reminder command through local decision-making, and interacting with the smart home terminal 150 via the Internet 130 to trigger the reminder operation; or, it can be executed based on multi-party data interaction between the vehicle terminal 140, the smart home terminal 150, and the backend server 110, using cloud computing power for status verification or strategy optimization, and this application does not limit it.

[0032] General Description of Embodiments in this Application Please refer to Figure 2 , Figure 2 A flowchart illustrating a method for reminding users of a forgotten mobile phone, as provided in an embodiment of this application, is shown. Figure 2 As shown, a mobile phone forgetting reminder method according to one embodiment of this application includes, but is not limited to, the following steps: Step 210: Detect the Bluetooth signal of the mobile phone inside the target vehicle using the multi-antenna Bluetooth detection unit of the target vehicle, and determine whether the mobile phone is left inside the target vehicle based on the Bluetooth signal. Step 220: Detect the operating status of the target vehicle; wherein, the category of the operating status includes the engine off and locked status; Step 230: Determine whether the driver and passengers of the target vehicle have returned home through multi-sensor fusion at the smart home terminal, generate a corresponding home return status signal, and send the home return status signal to the target vehicle through an encrypted communication link; Step 240: When the control unit of the target vehicle simultaneously determines that the mobile phone is inside the target vehicle, the target vehicle is in a locked and turned-off state, and the home status signal indicates that the driver and passengers have returned home, a reminder command is generated for the mobile phone. Step 250: Control the target vehicle to send the reminder command to the smart home terminal through the encrypted communication link, so as to trigger the smart home terminal to execute the preset reminder operation.

[0033] This application provides a method for reminding users when they forget their mobile phones. This method aims to improve the problem in related technologies where users forget their mobile phones in their cars after leaving their vehicles and there is a lack of effective cross-scenario linkage mechanisms, resulting in untimely, inaccurate, or poor user experience reminders. By constructing a reminder framework that enables collaborative perception, joint condition judgment, and cross-terminal triggering between the vehicle and smart home terminals, accurate and effective reminders for forgotten mobile phones can be achieved.

[0034] Specifically, this method first detects the Bluetooth signal of a mobile phone inside the vehicle using a multi-antenna Bluetooth detection unit to determine if the phone is left inside. Simultaneously, it detects the vehicle's operating status to confirm if it is in a locked, off-center state. Based on this, a smart home system uses multi-sensor fusion to sense whether the occupants have returned home and generates a home arrival status signal, which is then sent to the vehicle via an encrypted communication link. Finally, when the vehicle's control unit simultaneously determines that the phone is inside, the vehicle is locked, and receives a signal indicating that the occupants have returned home, it generates a reminder command for the phone and sends it to the smart home system via an encrypted communication link, triggering a preset reminder operation within the home environment. This method combines in-vehicle Bluetooth detection, vehicle status monitoring, home environment perception, and cross-device encrypted communication, enabling home-based reminders to be triggered only in high-probability scenarios where the user has returned home and the phone has indeed been forgotten. This significantly improves the accuracy of reminders and user experience, effectively solving the problem of users searching for their phones.

[0035] Below, in conjunction with Figure 2 This paper introduces and explains the various process steps of the mobile phone forgetting reminder method in the embodiments of this application.

[0036] In step 210, the Bluetooth signal of the mobile phone inside the target vehicle is detected by the multi-antenna Bluetooth detection unit of the target vehicle, and the mobile phone is determined to be left inside the target vehicle based on the Bluetooth signal.

[0037] In this embodiment, a multi-antenna Bluetooth detection unit integrated in the vehicle is used to actively and accurately detect Bluetooth signals within the target vehicle's interior space, which is crucial for determining whether a mobile phone has been left inside. This method differs from techniques that rely solely on door open / close signals or coarse scanning with a single Bluetooth antenna. Through a distributed multi-antenna layout and multi-dimensional signal analysis, it significantly improves the accuracy and reliability of the determination.

[0038] Specifically, in this embodiment, the multi-antenna Bluetooth detection unit may include at least four (e.g., six to eight) high-sensitivity Bluetooth signal receiving antennas. These antennas are optimally arranged in different locations within the vehicle, such as the front center console, the A-pillars on both sides, the headliner, and the top of the trunk, to form a three-dimensional coverage of the vehicle cabin (including the front and rear seat areas) and the trunk space, eliminating detection blind spots. When determining whether a mobile phone is left in the vehicle, the multi-antenna Bluetooth detection unit continuously or responsively scans the environment for mobile phone Bluetooth signals to obtain the corresponding result.

[0039] In step 220, the operating status of the target vehicle is detected.

[0040] In this embodiment, accurately obtaining the operating status of the target vehicle is a necessary prerequisite for triggering the forgetting reminder. This step aims to monitor the key vehicle status closely related to the user's departure from the vehicle in real time or near real time, especially whether the target vehicle has entered the safe parking state and the user has left, with the engine off and locked.

[0041] Specifically, when detecting the operating status of a target vehicle, the vehicle control unit can communicate in real time with the vehicle's powertrain controller, body controller, etc., via an onboard bus (such as the CAN bus). It monitors the status of the engine ignition switch or start button to determine whether the vehicle's powertrain system is off (i.e., in the off state). Simultaneously, it monitors the locking sensor signals of all doors (including the trunk lid). When the system detects that the ignition switch is in the "OFF" position and confirms through door lock status or central locking control signals that all doors have been successfully locked, it determines that the vehicle is currently in an off-state and locked state. This state is a direct indication that the user has parked, left the vehicle, and intends to leave.

[0042] In this embodiment, turning off and locking the vehicle is used as one of the conditions for triggering the reminder. This ensures that the reminder mechanism is only activated in risky scenarios where the user has actually left the vehicle. It avoids invalid or interfering reminders in scenarios where the vehicle is still in motion or temporarily stopped (such as refueling or briefly getting out of the car), thereby improving the relevance of the reminder and the user experience.

[0043] In step 230, the multi-sensor fusion of the smart home terminal determines whether the driver and passengers of the target vehicle have returned home, generates a corresponding home status signal, and sends the home status signal to the target vehicle through an encrypted communication link.

[0044] In this embodiment of the application, the determination of the user's home status by the smart home terminal is another condition for constituting cross-scene linkage. This step integrates information from multiple environmental sensors to intelligently and reliably identify the complex life scenario of the driver and passengers having returned home, thereby accurately positioning the triggering time of the reminder in the home environment where the user is most likely to need the reminder and can effectively receive the reminder.

[0045] Specifically, smart home devices (such as smart home gateways, smart speaker hubs, or smart door lock systems) integrate various sensors. Their decision-making logic typically employs a multi-condition collaborative verification approach. First, the smart door lock's status sensor detects whether the entrance door has undergone a state transition sequence from unlocked to locked, a common operation after someone enters the house. Second, using infrared human body sensors, millimeter-wave radar, etc., deployed indoors, it detects whether continuous human activity signals appear within a preset short period (e.g., 30 seconds) after the door lock transition. To further improve accuracy and distinguish between family members and visitors, the system can also compare detected human activity patterns (such as movement trajectories and frequently visited areas) with pre-learned or preset user behavior characteristics. Only when all three conditions (or subsets thereof, depending on configuration) are met simultaneously—door unlock-lock, continuous human activity detected indoors, and activity characteristics matching the user—do the smart home processing unit determines that the occupant (e.g., the car owner) has returned home and generates a corresponding home arrival status signal. The home status signal is sent to the vehicle via a pre-established, encrypted internet-based communication link (such as a TCP / IP connection with AES encryption) as one of the inputs for the vehicle to make comprehensive decisions.

[0046] In step 240, when the control unit of the target vehicle simultaneously determines that the mobile phone is inside the target vehicle, the target vehicle is in a locked and off state, and the home status signal indicates that the driver and passengers have returned home, a reminder command is generated for the mobile phone.

[0047] In this embodiment, the vehicle-side control unit integrates information from the vehicle's own sensors and remote smart home devices. Only when three independently determined conditions (the phone is left in the car, the vehicle is turned off and locked, and the person has returned home) are met simultaneously does it confirm that a high-probability forgetting risk scenario has occurred, where the phone has been left in the locked car and the user has returned home, and generates a reminder instruction accordingly.

[0048] Specifically, the vehicle control unit continuously receives and maintains the "phone left in the vehicle" flag from step 210, the "vehicle off and locked" status from step 220, and the "homecoming status signal" delivered via an encrypted link from step 230. Internally, it implements a logical AND gate check. Only when all three inputs are logically true (or valid) does the control unit trigger a decision and generate a structured reminder instruction.

[0049] For example, a reminder instruction typically includes an instruction type identifier (such as a phone forgetting reminder) and related control parameters. These control parameters can be populated based on system configuration or user-defined settings, such as specifying a template ID or custom text for the reminder content, a suggested playback volume level, whether to enable repeated reminders, and the number and interval of repetitions. This collaborative triggering mechanism fundamentally avoids the high false alarm rate caused by single-condition triggering (such as reminding only when leaving the car), and also differs from existing technologies that do not consider whether the user has entered a valid environment for receiving reminders (home). This ensures that reminders are both necessary and timely, greatly improving the system's intelligence level and user acceptance.

[0050] In step 250, the target vehicle is controlled to send a reminder command to the smart home terminal via an encrypted communication link, thereby triggering the smart home terminal to execute a preset reminder operation.

[0051] In this embodiment, after the vehicle completes accurate scene determination and instruction generation locally, it does not issue a potentially invalid reminder on the vehicle (because the user has moved away from the vehicle), but instead delegates the execution action to the device in the user's current home environment.

[0052] Specifically, the vehicle controls its 4G / T-Box and other remote communication modules to send the reminder command generated in step 240 back to the smart home terminal via the secure encrypted communication link. The smart home terminal's communication module receives and decrypts the command, then parses the control parameters. Subsequently, the smart home terminal's control logic, based on the command content, schedules appropriate home devices to execute preset reminder operations. For example, it can control a smart speaker in the living room or bedroom to play a voice prompt at an appropriate volume, such as, "You may have left your phone in the car, please check." Besides voice announcements, reminder operations can also be extended to controlling smart bulbs to flash specific colors, popping up notifications on smart TVs or smart screens, etc. In this way, reminders are clearly and directly presented in the home life scenarios where users are most likely to perceive them, thereby improving the core pain point of users returning home to find their phones missing and searching everywhere without realizing they were in the car, completing a full closed loop from risk detection to effective notification.

[0053] It is understood that the mobile phone forgetting reminder method provided in this application improves the effectiveness of reminding users when their mobile phones are left in the car by linking the vehicle and smart home terminals. The target vehicle uses a multi-antenna Bluetooth detection unit to detect the mobile phone's Bluetooth signal inside the vehicle to determine if the phone is left inside and whether the vehicle is turned off and locked. Simultaneously, the smart home terminal uses multi-sensor fusion to determine if the occupants have returned home and sends this home status signal to the target vehicle via an encrypted communication link. After confirming that the mobile phone is left inside the vehicle, the vehicle is turned off and locked, and the occupants have returned home, the target vehicle's control unit generates a reminder command and sends it to the smart home terminal via an encrypted communication link, thereby triggering the execution of a preset reminder operation. This application achieves the accuracy of reminder timing through cross-scenario (vehicle and home) collaborative perception and decision-making; at the same time, by utilizing a reminder method in a home environment, it ensures that the reminder can be reliably perceived by the user, allowing the user to quickly know the location of the mobile phone, thus improving the effectiveness of the reminder and the user experience.

[0054] Specifically, in some embodiments, the method further includes: The system receives the communication address and device model of the smart home terminal input by the user through the central control touch screen of the target vehicle or the terminal software of the target vehicle, and records the communication address and device model into the storage unit of the target vehicle. The user's identity information and the Bluetooth identifier of the mobile phone used by the user are recorded into the storage unit; Based on the communication address of the smart home device, the encrypted communication link is established, and the encryption key of the encrypted communication link is synchronized to the smart home device.

[0055] This application provides a method for system initialization and secure pairing, which aims to establish a reliable device identity binding and secure communication foundation for subsequent cross-terminal communication and collaborative reminders, and ensure that the entire system operates reliably and securely among preset authorized devices.

[0056] Specifically, in this embodiment, when the vehicle owner uses this function for the first time, they need to manually input or select from a device list the smart home devices that need to be linked with their vehicle, such as a smart speaker in the living room or a smart door lock at the entrance, through the settings interface integrated on the vehicle's central control touchscreen or through a dedicated mobile app (which can be paired with the vehicle's infotainment system). The input information must include at least the addressable information of the smart home device in the network, such as its IP address in the home LAN, the device's unique ID (such as MAC address or serial number), and usually the device model must also be selected or entered to ensure compatibility. This information is recorded and permanently stored in a non-volatile storage unit on the vehicle side. At the same time, the system also needs to bind the user's identity (e.g., through account login or vehicle owner identity verification) and the unique Bluetooth identifier (such as Bluetooth MAC address) of the mobile phone used as a digital key. This is the key to the vehicle side being able to accurately identify the target mobile phone from among many Bluetooth devices.

[0057] After completing the device information entry, the communication link establishment phase begins. The vehicle initiates a connection request based on the stored smart home device's communication address. To ensure communication security and prevent data leakage or unauthorized access, this embodiment employs encryption and two-way authentication mechanisms during connection establishment. A typical implementation involves the vehicle generating or obtaining an Advanced Encryption Standard (AES) key from the cloud. During the initial connection attempt, the vehicle and smart home devices exchange and verify a dynamically generated, one-time verification code (e.g., by scanning a QR code, entering a PIN code, or relaying through a trusted cloud service) to complete two-way device authentication and confirm the devices as legitimate and trustworthy. After successful authentication, the vehicle synchronizes the AES encryption key to the smart home device via a secure channel (e.g., based on temporary session key encryption). Subsequently, all status signals and command transmissions between the vehicle and smart home devices will be encrypted and decrypted using this shared AES key, thereby establishing a secure dedicated virtual channel over the public internet. The entire initialization process typically features a clear guided interface and status prompts to ensure users can successfully complete the configuration.

[0058] It is understandable that the initialization method provided in this application establishes a precise binding relationship across devices (vehicle, home, mobile phone) through a structured information entry process, laying the foundation for subsequent precise perception and collaborative control. More importantly, the introduction of a dynamic verification-based two-way identity authentication and AES key synchronization mechanism ensures system security from the source of communication link establishment, effectively preventing man-in-the-middle attacks, data theft, or unauthorized device impersonation, protecting user privacy and vehicle control security, and making the entire vehicle-home linkage solution both convenient and reliably secure.

[0059] Specifically, in some embodiments, determining whether the mobile phone is inside the target vehicle based on the mobile phone's Bluetooth signal includes: Detect whether the Bluetooth signal of the mobile phone matches the Bluetooth identifier of the pre-recorded mobile phone; When it is determined that the mobile phone Bluetooth signal and the Bluetooth identifier match, and the strength of the mobile phone Bluetooth signal is continuously greater than a preset threshold for more than a first duration, it is determined that the mobile phone is left inside the target vehicle, and the identity information of the driver and passenger corresponding to the left-behind mobile phone is determined according to the Bluetooth identifier.

[0060] This application provides a method for accurate in-vehicle mobile phone location determination based on triple verification of identity, strength, and duration. It aims to reliably distinguish whether a mobile phone is temporarily placed or truly forgotten in the vehicle from a complex wireless signal environment, and associate it with the specific user identity, providing a basis for subsequent personalized reminders.

[0061] Specifically, in this embodiment, the determination method is a step-by-step logical judgment process. First, the vehicle continuously scans all Bluetooth broadcast signals received by its multi-antenna Bluetooth detection unit. For each captured signal, the system extracts the unique device identifier carried in its broadcast packet, such as the Bluetooth MAC address. This identifier is compared with a list of Bluetooth identifiers for one or more authorized mobile phones pre-stored in the vehicle's secure storage unit. This list is typically entered by the vehicle owner through the in-vehicle system or a dedicated app during system initialization. Only when the detected signal identifier completely matches any record in the list is the "first layer of identity verification" passed, confirming it as the target mobile phone, rather than the device of other passengers or passersby. This step is the basis for accurate alerts, avoiding triggering alerts for irrelevant devices.

[0062] After confirming the identity, the system reads the received signal strength indicator value of the matched signal. Due to the enclosed effect of the metal body inside the vehicle, the Bluetooth signal strength is usually significantly higher than outside. This application sets an empirical signal strength threshold (e.g., -60dBm) through experiments or calibration. When the strength value of the matched signal consistently exceeds this preset threshold, the system initially determines that the phone is likely inside the vehicle. However, relying solely on a momentary strong signal may lead to misjudgments due to fluctuations caused by changes in the phone's posture in a pocket, hand obstruction, or environmental interference. Therefore, this application introduces time stability verification. The system uses a timer to monitor the continuous duration of the signal strength exceeding the preset threshold. Only when this state is maintained for more than a preset "first duration" (e.g., 3 seconds) is a definitive determination made that "the phone is left inside the car." This first duration setting filters out momentary strong signals generated by a user temporarily bending over to retrieve something from the car or the phone briefly remaining at the car door, ensuring that the determination is based on real-world scenarios where the phone is relatively stationary and left in a seat, storage compartment, or other similar location.

[0063] Furthermore, because the system stores the binding relationship between Bluetooth identifiers and user identities (such as "driver" or "frequent passenger A"), when making a detention decision, it can immediately retrieve and determine the specific driver or passenger identity information corresponding to the detained mobile phone based on the currently matched Bluetooth identifier. For example, the system can mark it as "the owner's (driver's) mobile phone has been forgotten" or "passenger A's mobile phone has been forgotten." This provides data support for potentially more refined reminder strategies (such as reminding different people through different home devices).

[0064] Understandably, the determination method provided in this application embodiment improves the accuracy of determining the presence of a mobile phone inside the vehicle. It not only effectively eliminates external interference signals and non-target devices, but also avoids false triggers caused by brief user operations through time-based verification, enabling the system to accurately identify the specific state of forgetting. Simultaneously, the ability to associate user identity lays the foundation for building a user-centric intelligent vehicle-home service ecosystem, enhancing the system's intelligence and personalization level.

[0065] Specifically, in some embodiments, determining whether the occupants of the target vehicle have returned home through multi-sensor fusion at the smart home terminal includes: Based on the identity information of the driver and passengers corresponding to the detained mobile phones, the target personnel to be identified are determined; The status of the door lock is detected through the smart home terminal; If the state of the door lock changes, the smart home terminal detects whether the target person exists in the surrounding area. If the target person exists, determine that the driver and passengers of the target vehicle have returned home.

[0066] This application provides a method for accurately determining whether someone has returned home based on event triggering and personnel orientation identification. The aim is to intelligently and accurately identify, from the complex activities in the home environment, whether a specific driver or passenger who has forgotten their mobile phone in the car has returned home, thereby accurately linking the triggering of the reminder to the actual risk bearer and avoiding unnecessary interference to other family members.

[0067] Specifically, in this embodiment, the initiation of the determination process is closely related to the identification of the target object. After determining that the mobile phone is left inside the vehicle, the vehicle terminal simultaneously generates and sends a pre-triggered signal containing the identity information of the driver and passenger corresponding to the left-in mobile phone to the smart home terminal. Upon receiving this information, the smart home terminal clearly identifies the target person to be monitored and determined as A, rather than other family members or visitors. This makes the subsequent sensor data collection and analysis highly targeted, which is a prerequisite for accurate identity recognition.

[0068] Subsequently, the smart home system initiates a monitoring process triggered by changes in door lock status. The door lock's (usually the smart lock on the front door) status sensor continuously operates, reporting its status in real time. The system monitors whether a specific sequence of changes in the door lock status has occurred, representing a possible entry of a person. A typical sequence is: from locked to unlocked (open), and after a short time interval, back to locked (closed). This sequence of events represents a high-probability behavioral characteristic of a person entering the home from the outside and completing entry, and is used as a trigger to initiate subsequent person identification.

[0069] When a change in door lock status matching the preset pattern is detected, it is determined that someone may have entered, and the indoor personnel detection and identification process is activated. This process utilizes the environmental perception capabilities integrated into the smart home system, such as facial recognition via wide-angle cameras deployed in areas like the entryway and living room, or detection of human movement trajectories using millimeter-wave radar with directional recognition capabilities, and matching them with preset user behavior models (such as A's habitual home route). The system compares the currently detected person's biometric or behavioral characteristics with the preset characteristics of the target person identified in the previous steps. Here, detection does not refer to general human activity, but specifically to detecting the target person. If the characteristics match successfully, the presence of the target person is confirmed, i.e., "the occupant A of the target vehicle has returned home." If the door lock change detects another family member, this determination process terminates.

[0070] It is understood that the home arrival determination method provided in this application embodiment, through information linkage between the vehicle and home terminals (transmitting the target's identity), utilizes changes in door lock status as an efficient event trigger, and ultimately confirms identity through biometric or behavioral feature recognition, forming a complete and reliable determination chain. This method greatly reduces false system activation caused by the normal entry and exit of other family members, ensuring the high accuracy and intelligence of the reminder mechanism, truly achieving effective reminders at the right time for the right person, and significantly improving the system's usability and user experience.

[0071] Specifically, in some embodiments, sending the reminder instruction to the smart home device to trigger the smart home device to perform a preset reminder operation includes: Send the reminder command to the smart home terminal; The current ambient noise is detected through the smart home terminal; The broadcast volume is determined based on the ambient noise, and a reminder operation is performed based on the reminder instruction and the broadcast volume.

[0072] This application provides an intelligent voice reminder method that adapts to ambient noise, aiming to solve the problem that fixed-volume reminders may be masked by excessive noise or become abrupt and disruptive in complex home scenarios. By sensing the ambient acoustic conditions in real time and dynamically adjusting the output volume, the method ensures that reminder information can be conveyed to the user in a clear, comfortable, and effective manner.

[0073] Specifically, in this embodiment, when the smart home device receives the reminder instruction from the vehicle via an encrypted communication link, it does not immediately broadcast the message at a preset fixed volume. Instead, the system first initiates an environmental perception subprocess. The smart home device (usually a smart speaker, smart control screen, or other device with audio input / output capabilities) uses its built-in microphone array to collect background sound signals of the current indoor environment momentarily before broadcasting (e.g., within 0.5 seconds). The system quickly analyzes this audio signal to quantify the environmental noise level. This detection process is fast and accurate, effectively identifying whether the environment is relatively quiet (e.g., at night), has continuous moderate noise (e.g., television sound, conversation), or has momentary high noise (e.g., kitchen range hood sound).

[0074] After obtaining the specific value of the current ambient noise, the system proceeds to the volume decision stage. This embodiment of the application pre-defines a set of volume adjustment logic. For example, a target signal-to-noise ratio (SNR) can be set, meaning the desired volume of the reminder voice is higher than the ambient noise by a suitable difference (e.g., 15-20 dB) to ensure clear and intelligible speech. The system calculates the target broadcast volume value based on the detected ambient noise value plus this pre-determined SNR difference. Simultaneously, the system also considers user preferences (such as maximum volume limits or silent night mode) that may be pre-set in the app, as well as the device's own safe volume limit, to ensure compliance with regulations, ultimately determining a broadcast volume level that guarantees audibility while meeting safety and comfort requirements.

[0075] The audio processing unit at the smart home end generates and outputs the final audio drive signal based on the reminder content (such as text or voice template identifier) ​​specified in the received reminder instruction, combined with the dynamically determined playback volume parameters. For example, at a quiet night, the system might gently play the reminder at 30% volume; while during the day, when the living room TV is playing, the system might automatically increase the volume to 60% to ensure penetration. In this way, the reminder operation is no longer mechanical and unchanging, but possesses intelligent characteristics of environmental perception and adaptive adjustment.

[0076] Understandably, the adaptive noise alert method provided in this application significantly improves the user experience and reliability of the alert function. It enables the alert to intelligently integrate into the current home acoustic environment, preventing it from being ignored due to insufficient volume in noisy environments and avoiding disturbance due to excessive volume in quiet environments. This intelligent attention to detail demonstrates that this application not only focuses on functional implementation but also strives to provide a humanized, seamless proactive service, thereby addressing users' actual pain points while enhancing the overall usability and user satisfaction of the product.

[0077] Specifically, in some embodiments, the reminder operation based on the reminder instruction and the broadcast volume includes: According to the reminder instruction, perform a reminder operation according to the broadcast volume; The smart home device detects whether the driver or passenger provides any feedback or response. If the driver or passenger does not provide feedback, after waiting for a preset interval, the step of performing a reminder operation according to the reminder instruction and the broadcast volume is repeated until the driver or passenger provides feedback or the preset number of repeated reminders is reached.

[0078] This application provides an intelligent recurring reminder mechanism based on feedback detection, aiming to solve the problem that a single reminder may not be received in time due to the user's temporary inattention, being in a different room, or being busy with other things. This mechanism actively monitors user feedback and provides orderly, non-intrusive recurring reminders when there is no response, ensuring that key information is reliably delivered while avoiding endless harassment, thus achieving a balance between reminder reliability and user experience.

[0079] Specifically, in this embodiment, the mechanism is a logical closed loop comprising execution, monitoring, judgment, and iteration. After the initial reminder operation (e.g., a voice announcement that your phone may have been left in your car), the system does not immediately end the task but immediately initiates a feedback monitoring window. During this window, the smart home device utilizes its multimodal perception capabilities to proactively detect whether the target driver / passenger (i.e., the person who forgot their phone) has made any identifiable feedback response to the reminder. This feedback detection is intelligent and non-intrusive. For example, the system can monitor and identify whether the user has uttered a preset confirmation command (such as "I understand" or "okay") through a microphone array; or it can detect whether the user has made actions such as walking towards the door or picking up keys to retrieve their phone through a camera combined with visual algorithms; or it can sense whether the user has clearly approached the device (smart speaker) that broadcast the reminder to show attention through millimeter-wave radar; more directly, the system can receive a "received" confirmation signal proactively sent by the user through a mobile app (if the user logs in using another device) or a smart home control panel. The system will integrate this multi-source information to determine whether there is a valid feedback response.

[0080] If no valid feedback is detected within the preset feedback listening window (e.g., 5-10 minutes after the initial reminder), the system determines that the reminder may not have been effectively received by the user. In this case, the system will not immediately issue another reminder, but will instead enter a "waiting interval" (e.g., 5 minutes). This provides the user with sufficient time to react and act, while also avoiding the annoyance caused by continuous voice announcements. After the interval ends, the system will automatically trigger a new reminder cycle: again, the volume will be adaptively adjusted based on the current ambient noise (which may differ from the first time due to environmental changes), and the same reminder content will be announced. Afterward, the system will reopen the feedback listening window.

[0081] This cycle of reminder-listening-waiting-reminding will continue until one of two termination conditions is met: first, the system detects a valid response from the user, indicating that the reminder has been successfully delivered and acknowledged, and the task is successfully completed; second, the number of repeated reminders reaches a preset limit (e.g., a maximum of 3 times). If no feedback is received after reaching the limit, the system may log this event and may report it through other backup channels (such as sending notifications to other associated devices), but will stop proactive voice broadcasts on the current home appliance to prevent it from becoming an unnecessary nuisance.

[0082] It is understandable that the intelligent repetitive reminder mechanism provided in this application embodiment ensures the success rate of information transmission through multiple attempts, effectively addressing the actual situation of temporary distraction of user attention. At the same time, its feedback-based termination conditions, preset intervals, and frequency limits ensure that repetitive reminders are controlled and moderate, reflecting intelligent adaptation to users' life scenarios.

[0083] It is understood that the technical solution of this application has at least the following advantages: 1. Solves the pain point of reminders failing when the user is away from the vehicle: By building a cross-scenario linkage architecture between vehicle detection and smart home reminders, the reminder scenario is extended from the vicinity of the vehicle to the inside of the user's living space. This enables reminders to be reliably detected even in scenarios where the user has returned home and is likely to forget, effectively solving the problem of users not being able to receive reminders when they are away from the vehicle.

[0084] 2. Significantly improved reminder accuracy: The system employs a three-condition triggering logic that combines vehicle ignition and locking, mobile phone left in the vehicle, and owner returning home. This, along with multi-antenna precise detection and multi-sensor fusion for home arrival determination, verifies forgotten scenarios from multiple dimensions, greatly reducing invalid or erroneous reminders caused by mis-triggered reminders due to a single condition.

[0085] 3. Optimized user experience: The reminder method is adaptive, automatically adjusting the output volume according to ambient noise to ensure clear hearing, and supports personalized customization of voice content. It also integrates feedback detection and intelligent repeat reminder mechanism to ensure that reminders can reach users in a timely, effective and user-friendly manner.

[0086] 4. Communication security and privacy are guaranteed: By adopting advanced encryption standard algorithms and two-way identity authentication mechanisms, the security of all status and command data transmission between the vehicle and smart home terminals is ensured, effectively preventing data leakage and unauthorized device access, and protecting user information and vehicle control security.

[0087] 5. Wide compatibility and application prospects: This solution is based on mainstream Bluetooth mobile phones, vehicle communication modules and common smart home devices. It does not require complex modifications to the user's existing devices or require the user to carry additional dedicated hardware. It has a low deployment threshold and good universality and large-scale application potential.
