Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an unlocking method, device, and vehicle. Background Technology

[0002] Currently, the automotive industry is rapidly moving towards intelligence, personalization, and security. Among these advancements, vehicle access technology has undergone significant changes, evolving from the initial mechanical keys to remote keys, and now to the widely used intelligent keyless entry systems, greatly improving user convenience. Vehicle security has long been a core issue in the industry's development and a focus of technological innovation. Therefore, for current users, relying solely on keyless entry systems to unlock their vehicles still presents certain security risks. Summary of the Invention

[0003] In view of this, the purpose of this application is to propose an unlocking method, device and vehicle to solve the technical problem of poor security in related technologies.

[0004] To achieve the above objectives, a first aspect of this application provides an unlocking method applicable to a mobile terminal, the unlocking method comprising: The user's biometric information is obtained based on the user's operation request, the obtained biometric information is stored in a database, and the biometric information in the database is compared with the pre-authorized identification information. In response to determining that the biometric information matches the pre-authorized identification information successfully, and determining that the current mode is unlock mode or screen-off mode, the biometric information is sent to the vehicle system so that the vehicle system can unlock the vehicle; In response to determining that the vehicle system has received the biometric information, the database is formatted.

[0005] Based on the same inventive concept, a second aspect of this application also provides an unlocking method applicable to in-vehicle infotainment systems, the unlocking method comprising: Receive biometric information sent by a mobile terminal and compare the received biometric information with pre-authorized identification information; In response to determining that the biometric information matches the pre-authorized identification information successfully, the received biometric information is deleted, the key signal of the key is received through the vehicle's low-frequency antenna, and the vehicle is unlocked based on the received key signal.

[0006] Based on the same inventive concept, a third aspect of this application also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor implements the method described above when executing the computer program.

[0007] Based on the same inventive concept, a fourth aspect of this application also provides a vehicle including the electronic equipment described above.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0012] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0013] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0014] In related technologies, with the rapid advancement of information technology and the increasing demand from consumers for intelligence and personalization, the automotive industry is accelerating its intelligent transformation. Traditional vehicle unlocking methods are no longer sufficient to meet the market's high standards for efficiency, security, and user experience. Therefore, the integration of identity recognition technology and modern communication technology to innovate vehicle access control systems has become a key path to promote the upgrading of automotive security technology.

[0015] Currently, keyless entry is the mainstream access method for unlocking and closing vehicles when leaving the vehicle. It uses digital keys to replace traditional physical keys to improve the convenience and flexibility of vehicle control. As the core of the vehicle's electronic system, the vehicle controller's increased intelligence enables it to handle complex logical judgments and security verification tasks, such as integrating user authentication and user location detection functions, providing strong support for realizing intelligent vehicle unlocking.

[0016] Therefore, the main unlocking methods for vehicles currently typically involve remote unlocking with digital keys, or automatic unlocking via keyless entry systems that detect the presence of a user carrying a digital key near the vehicle. These systems can be combined with user authentication mechanisms, such as fingerprint or facial recognition, to determine if the user is the owner or authorized user, thereby improving overall vehicle security. However, unlocking vehicles with digital keys still has its drawbacks. Due to the continuous development of internet technology, when the owner or authorized user uses their personal identification information to lock or unlock the vehicle, this information can be maliciously obtained by criminals, leading to information leaks and increasing the risk of vehicle theft. Since the user's identity information is crucial for unlocking the vehicle, it can cause the vehicle's off-vehicle unlocking function to malfunction, or even result in the theft of valuables or the vehicle itself, making it difficult to guarantee vehicle security.

[0017] In view of this, this application provides an unlocking method applicable to mobile terminals, with the mobile terminal as the executing entity, such as... Figure 1 As shown, the unlocking methods include: S110: Obtain the user's biometric information based on the user's operation request, store the obtained biometric information in a database, and compare the biometric information in the database with pre-authorized identification information; In this step, a mobile terminal can be used to obtain the user's operation request and, based on the user's operation request, obtain the user's biometric information for preliminary verification of the user's identity. The mobile terminal can be a smartphone or smartwatch, among other devices. Specifically, when verifying the user's identity using the mobile terminal, the user can input an operation request through the mobile terminal's function keys, such as triggering the biometric information collection button. After receiving the operation request, the mobile terminal can collect the user's biometric information through its biometric information collection module and store the acquired biometric information in a database for user identity verification. Subsequently, when verifying the user's identity, the biometric information stored in the database can be retrieved and compared with pre-authorized identification information to determine whether the acquired biometric information matches the pre-authorized identification information, thereby determining whether the user is the vehicle owner or an authorized user.

[0018] The following further explains the user's biometric information and the biometric information acquisition module in conjunction with the above steps. The user's biometric information can be static biometric information, such as fingerprints, facial features, and iris scans, or it can be dynamic biometric information with a higher security level, such as gestures and facial expressions. Therefore, based on the biometric information mentioned above, the mobile terminal can obtain the user's biometric information through a corresponding biometric information acquisition module, such as a fingerprint acquisition module or an image acquisition device, to ensure the completeness and accuracy of the biometric information acquisition. In addition, the database mentioned above can be a storage module within the mobile terminal or a cloud server, so that the mobile terminal can store, retrieve, or delete the acquired biometric information; pre-authorized identification information can be pre-built and stored in the mobile terminal for easy retrieval and use when verifying biometric information, which will not be elaborated here.

[0019] S120: In response to determining that the biometric information matches the pre-authorized identification information successfully, determine that the current mode is unlock mode or screen-off mode, and send the biometric information to the vehicle system so that the vehicle system can unlock the vehicle; In this step, after the mobile terminal obtains the user's biometric information, it determines whether the obtained biometric information matches the pre-authorized identification information. Specifically, when the mobile terminal determines that the obtained biometric information matches the pre-authorized identification information, it can determine that the user operating the mobile terminal is the vehicle owner or an authorized user. At the same time, based on the current mode of the mobile terminal, the user's vehicle usage intention is further determined. Since there is a communication connection between the mobile terminal and the vehicle's infotainment system, when it is determined that the current mode of the mobile terminal is unlock mode or screen-off mode, the mobile terminal can send the biometric information matching the mobile terminal to the vehicle's infotainment system for unlocking, thus meeting the user's unlocking needs, preventing the vehicle from being maliciously unlocked, and improving the overall vehicle security.

[0020] S130: In response to determining that the vehicle system has received the biometric information, the database is formatted.

[0021] In this step, after the successfully matched biometric information is sent to the vehicle's infotainment system via a mobile terminal, the mobile terminal can also verify the vehicle's reception of the biometric information, thus indicating that the user operating the mobile terminal is the vehicle owner or authorized user. Specifically, when the mobile terminal receives a confirmation message from the vehicle's infotainment system, indicating that the mobile terminal has successfully received the biometric information, it means that the mobile terminal has successfully sent the biometric information. At this time, the mobile terminal will format the biometric information stored in the database to prevent the leakage of the user's biometric information, avoid criminals unlocking the vehicle using the retained biometric information, thereby increasing the risk of theft and improving the overall security of the vehicle.

[0022] Specifically, such as Figure 1 As shown, using a mobile terminal as the execution entity, after receiving a user's operation request, the mobile terminal obtains the user's biometric information based on the request and stores it in a database. It then compares the biometric information in the database with pre-authorized identification information to verify if the user is the vehicle owner or an authorized user. When the mobile terminal determines that the obtained biometric information matches the pre-authorized identification information, the user passes the mobile terminal's verification, and the user is confirmed as the vehicle owner or authorized user. Since there is a communication connection between the vehicle's infotainment system and the mobile terminal, the mobile terminal can send the matched biometric information to the vehicle's infotainment system. After sending the biometric information matched by the mobile terminal to the vehicle's infotainment system, the mobile terminal determines whether the vehicle's infotainment system has received the biometric information and prompts the user to complete the initial unlocking of the vehicle. When the mobile terminal receives a confirmation message from the vehicle's infotainment system, it indicates that the biometric information was successfully sent. At this point, the mobile terminal formats the biometric information in the database to prevent user information leakage, avoid malicious unlocking of the vehicle by retaining biometric information, reduce the risk of vehicle theft, and improve vehicle security.

[0023] Therefore, as can be seen from the above, the unlocking method provided in this application compares and verifies the acquired user's biometric information to determine whether the user is the vehicle owner or authorized user through pre-authorized identification information, ensuring the accuracy of vehicle unlocking. After the biometric information verification is completed, the matched biometric information is also deleted to avoid leakage of user information, reduce the risk of malicious vehicle unlocking, enhance the overall vehicle security, and protect user privacy. In addition, using a mobile terminal to verify the user's biometric information can reduce vehicle cost investment, reduce interference from external factors in the acquisition and transmission of biometric information, and help improve the accuracy of vehicle unlocking.

[0024] In some embodiments, sending biometric information to the vehicle's infotainment system includes, prior to: S121: Determine the first distance to the vehicle based on the obtained vehicle location information; In this step, before sending biometric information to the vehicle's infotainment system using the mobile terminal, the distance between the mobile terminal and the vehicle can be determined to further determine whether the user intends to use the vehicle. Since a communication connection is established between the mobile terminal and the vehicle's infotainment system, the mobile terminal can obtain the vehicle's location information through the infotainment system. Then, based on the location information of the mobile terminal and the vehicle, the first distance between the two can be determined to judge the user's intention to use the vehicle and ensure the accuracy of unlocking the vehicle.

[0025] S122: In response to the first distance being greater than the first preset distance, a risk warning message is generated and sent to the user, so as to determine whether to continue sending biometric information according to the user's instructions; In this step, after the mobile terminal determines the first distance between the mobile terminal and the vehicle, it can judge the user's intention to use the vehicle based on the first distance. If the first distance determined by the mobile terminal is greater than a first preset distance, it means that the distance between the user operating the mobile terminal and the vehicle is too far. At this time, the mobile terminal generates a risk warning message and sends it to the user, reminding the user that unlocking the vehicle is risky under the current circumstances, and asking whether the user should continue to send biometric information to the vehicle system to support the vehicle system to continue to initially unlock the vehicle.

[0026] In addition, the mobile terminal can continue sending biometric information or stop sending biometric information based on user feedback. For example, when a user receives a risk warning message via mobile and can reach the vehicle within a short period of time (e.g., 1-10 minutes), the user can enter the "continue execution" command into the mobile terminal to complete the remote verification of the vehicle. For example, if the user is inside a building, biometric information can be sent to the vehicle downstairs in advance to shorten the waiting time when using the vehicle. If the user is in another location, biometric information can be sent to a vehicle located locally in advance to perform remote identity verification so that other authorized users can unlock the vehicle with a spare key, improving the flexibility of vehicle use. When a user receives a risk warning message via mobile and no longer wants to use the vehicle, the user can enter the "stop execution" command into the mobile terminal to stop sending biometric information and stop remote verification. This is for example, if the user has something urgent to attend to and stops using the vehicle, or if the user makes an operational error, to ensure vehicle security. S123: In response to the first distance being less than or equal to the first preset distance, biometric information is sent to the vehicle system.

[0027] In this step, when the mobile terminal determines that the first distance is less than or equal to the first preset distance, it means that the user carrying the mobile terminal is relatively close to the vehicle, that is, the user has moved to the vicinity of the vehicle. Therefore, the user has a higher probability of unlocking the vehicle and a relatively high demand for vehicle use. Since the mobile terminal establishes a communication relationship with the vehicle system, the mobile terminal can send biometric information to the vehicle system. After the vehicle system receives the biometric information, it is conducive to completing the initial unlocking of the vehicle, thereby shortening the user's waiting time while ensuring vehicle security.

[0028] In some embodiments, the database is formatted, prior to which the following steps are performed: S131: Mark the biometric information in the database as invalidation feature information, record the number of invalidation feature information entries in the database, generate invalidation prompt information and send it to the user to prompt the user that the biometric information has expired; In this step, the mobile terminal can send biometric information to the vehicle's infotainment system for unlocking. Since the matched biometric information is still stored in the database, to prevent the retained biometric information from affecting the next unlock, the mobile terminal can mark the sent biometric information in the database as invalid feature information and record the number of invalid feature information entries in the database. At the same time, the mobile terminal will also generate an invalidation prompt message and send it to the user to inform the user that the sent biometric information has expired and that new biometric information is required for identity verification.

[0029] S132: In response to the determination that the number of failure feature information entries has reached a preset storage threshold, the database is formatted to clear the failure feature information in the database.

[0030] In this step, biometric information that has been sent from the database is marked as invalid feature information to prevent the reuse of matched biometric information, which would reduce the accuracy of mobile terminal authentication. Specifically, when a preset storage threshold for the amount of biometric information in the mobile terminal database is determined, the database can be formatted to clear invalid feature information. This increases database storage space, preventing it from affecting the storage of subsequent invalid feature information, and also prevents the leakage of invalid feature information, reducing the risk of vehicle theft. The preset storage threshold can be set based on the mobile terminal's settings. For example, the preset storage threshold can be set to one or at least two. When the preset storage threshold is set to one, the risk of biometric information leakage is reduced, ensuring sufficient storage space for invalid feature information and better security. When the preset storage threshold is set to at least two, the frequency of database formatting by the mobile terminal is reduced, alleviating the computational burden and reducing power consumption.

[0031] In some embodiments, the unlocking method further includes: In response to determining that the current mode is lock screen mode, the system stops sending biometric information to the vehicle system, formats the database to clear the failure feature information in the database, and keeps the vehicle locked.

[0032] In practice, after obtaining the user's biometric information based on the user's operation request, the mobile terminal can judge the obtained biometric information based on pre-authorized identification information to determine the user's vehicle usage needs. When it is determined that the user's biometric information matches the mobile terminal's biometric information, it means that the user has passed the mobile terminal's identity verification and has a vehicle usage need. To meet the user's vehicle usage needs, the mobile terminal can send the user's biometric information to the vehicle's infotainment system for the system to re-verify the user's identity and perform initial unlocking. More specifically, if the mobile terminal is in lock screen mode when sending biometric information to the vehicle's infotainment system, it means that the user has stopped operating the mobile terminal, and no further identity verification is required, so the probability of the user refusing to use the vehicle is relatively high. At this time, the mobile terminal can stop sending biometric information to the vehicle's infotainment system, reducing the mobile terminal's energy consumption. At the same time, the mobile terminal can also format the database to clear the biometric information that has been stopped from being sent. This can prevent the mobile terminal from continuing to send biometric information to the vehicle's infotainment system after unlocking, thus improving the accuracy of vehicle unlocking. On the other hand, it can ensure that the database has sufficient memory, avoiding insufficient memory from affecting the next identity verification.

[0033] In some embodiments, the unlocking method further includes: S141: In response to the failure of matching biometric information with pre-authorized identification information, record the number of matching failures, generate a matching failure prompt message and send it to the user; In this step, after obtaining the user's biometric information using a mobile terminal, the mobile terminal compares the obtained biometric information with pre-authorized identification information to verify whether the user providing the biometric information is the vehicle owner or an authorized user. For the mobile terminal, if the biometric information obtained by the mobile terminal fails to match the pre-authorized identification information, the mobile terminal can record the number of matching failures to determine whether there is malicious unlocking of the vehicle through the mobile terminal. At the same time, the mobile terminal will also generate a matching failure prompt message to remind the user that the currently entered biometric information cannot pass the verification, the mobile terminal cannot confirm that the user is the vehicle owner or an authorized user, and therefore the conditions for unlocking the vehicle are not met.

[0034] It should be noted that if the obtained biometric information fails to match the pre-authorized identification information, the mobile terminal can directly delete the failed biometric information to avoid interference from the matched biometric information on the mobile terminal's ability to obtain the next biometric information, thereby improving the accuracy of user authentication.

[0035] S142: In response to determining that the number of consecutive matching failures has reached a preset fault tolerance threshold, activate security verification; In this step, after the mobile terminal determines that the obtained user's biometric information fails to match the pre-authorized features, it will record the number of failures to determine whether there is malicious unlocking behavior based on the number of matching failures. If the number of matching failures between the obtained biometric information and the pre-authorized biometric information reaches a preset fault tolerance threshold, it indicates that the mobile terminal has maliciously unlocked the vehicle. At this time, the mobile terminal can activate security verification to further verify whether the user operating the mobile terminal is the vehicle owner or an authorized user.

[0036] The preset fault tolerance threshold is further explained in conjunction with the above steps. The preset fault tolerance threshold can be the maximum number of consecutive failed biometric matching attempts allowed by the mobile terminal, and this preset fault tolerance threshold can be preset in the mobile terminal. For example, the preset fault tolerance threshold can be set to three times. When the number of consecutive failed biometric matching attempts reaches three, the acquisition of biometric information is suspended, and then the security verification of the mobile terminal is activated, and the user's identity is further verified.

[0037] S143: In response to the confirmation that the security verification has been released, a low-frequency antenna activation command is sent to the vehicle's infotainment system to format the biometric information in the database and send a low-frequency antenna activation command to the vehicle's infotainment system so that the vehicle's infotainment system can receive the key signal from the key via the low-frequency antenna.

[0038] In this step, after the mobile terminal activates the security verification, it needs to further verify the user's identity to confirm whether the user is the vehicle owner or an authorized user. Due to the high complexity and cumbersome process of security verification, its security level can be set higher than that of biometric information. For example, the security verification could be a pre-set security question on the mobile terminal. When the mobile terminal determines that the security verification has been deactivated, it can confirm that the user is the vehicle owner or an authorized user. However, there may be issues with obtaining complete biometric information or obtaining incomplete biometric information, leading to verification failure. In such cases, the mobile terminal can directly delete the matched biometric information from the database to avoid affecting subsequent vehicle unlocking. Furthermore, since the security level of security verification is higher than that of biometric information, the mobile terminal can directly send a low-frequency antenna activation command to the vehicle's infotainment system, allowing the system to receive the key signal via the low-frequency antenna, thus addressing the issue of users being unable to unlock the vehicle using biometric information.

[0039] Based on the same inventive concept, this application also provides an unlocking method, with the vehicle's infotainment system as the executing entity, applicable to vehicle infotainment systems, such as... Figure 2 As shown, the unlocking methods include: S210: Receive biometric information sent by the mobile terminal and compare the received biometric information with pre-authorized identification information; In this step, the vehicle's infotainment system is the main execution entity. The infotainment system receives biometric information sent by the mobile terminal and can verify whether the biometric information sent by the mobile terminal can unlock the vehicle. In specific implementation, after receiving the biometric information sent by the mobile terminal, the infotainment system can compare the received biometric information with the pre-authorized identification information and determine whether the received identification information can be used to unlock the vehicle based on the pre-authorized identification information.

[0040] S220: In response to determining that the biometric information matches the pre-authorized identification information, the received biometric information is deleted, the key signal of the key is received through the vehicle's low-frequency antenna, and the vehicle is unlocked based on the received key signal.

[0041] In this step, when the vehicle's infotainment system determines that the received biometric information from the mobile terminal matches the pre-authorized identification information, it indicates that the user of the mobile terminal is the vehicle owner or authorized user and has a need to use the vehicle. At this time, in order not to affect the next unlocking process of the vehicle, the infotainment system can delete the received biometric information to prevent the leakage of user identity information, and can control the vehicle's low-frequency antenna to turn on so that the low-frequency antenna can receive the key signal from the key. Based on the reception of the key signal, the system can control the vehicle to unlock. That is, when the infotainment system receives the key signal from the key through the low-frequency antenna, it can control the vehicle to unlock, shorten the user's waiting time, and facilitate the user to use the vehicle in a timely manner.

[0042] Specifically, such as Figure 2 As shown, the vehicle's infotainment system (IMS) acts as the execution entity. The IMS verifies whether the biometric information sent by the mobile terminal can unlock the vehicle. Upon receiving the biometric information from the mobile terminal, the IMS compares it with pre-authorized identification information to determine if the received information is sufficient to unlock the vehicle. If the IMS determines that the received biometric information matches the pre-authorized information, it indicates that the user of the mobile terminal is the vehicle owner or authorized user and has a need to use the vehicle. At this point, the IMS deletes the received biometric information to prevent leakage of user identity information. Simultaneously, it controls the vehicle's low-frequency antenna to activate, reducing user waiting time when the IMS receives the key signal from the key via the low-frequency antenna.

[0043] Therefore, this application provides an unlocking method. After receiving biometric information sent by a mobile terminal, the method can further verify the received biometric information through the vehicle's infotainment system, and then control the low-frequency antenna to receive the key signal from the key, thereby completing the vehicle unlocking. This method is beneficial to further improve the accuracy and security of vehicle unlocking. In addition, since the vehicle obtains the user's biometric information through the mobile terminal, it has little impact on the overall vehicle structure and will not increase the vehicle's production cost, thus having good economic benefits.

[0044] In some embodiments, the key signal of the key includes the key's location information. Receiving the key signal via the vehicle's low-frequency antenna and controlling vehicle unlocking based on the received key signal includes: S2211: In response to determining that the low-frequency antenna has received the location information of the key, a second distance between the key and the vehicle is determined based on the location information of the key; In this step, the key signal can include the key's location information to determine the distance between the user carrying the key and the vehicle. In practice, after the vehicle system obtains the key's location information, it can determine the second distance between the key and the vehicle based on the vehicle's current location and the key's location information. Then, it can use the second distances corresponding to two adjacent moments to determine the user's movement trend in order to judge whether the user's probability of using the vehicle has increased.

[0045] S2212: In response to determining that the second distance at the current moment is less than the second distance at the previous moment, the vehicle is unlocked.

[0046] In this step, when the vehicle system determines that the second distance between the vehicle and the key at the current moment is less than the second distance between them at the previous moment, it means that the second distance between the user carrying the key and the vehicle has shortened. That is, compared to the previous moment, the user is closer to the vehicle at the current moment, so the probability of the user using the vehicle at the current moment increases. If the vehicle passes the biometric verification, the vehicle system can control the vehicle to unlock, so that the door can be opened directly when the user is next to the door, ensuring vehicle security while also meeting the user's needs for using the vehicle.

[0047] In some embodiments, the key signal of the key includes the signal strength of the key. Receiving the key signal via the vehicle's low-frequency antenna and controlling vehicle unlocking based on the received key signal includes: S2221: In response to determining the signal strength of the key received by the low-frequency antenna, determine the change in signal strength based on the signal strength at the current moment and the signal strength at the previous moment; In this step, the key signal can include the key's signal strength, and the change in the key's signal strength between different times can be used to determine the user's vehicle usage probability. In specific implementation, the vehicle system can acquire the signal strength of the key at two corresponding times in chronological order, and determine the change in signal strength between the two times based on the signal strength at the two times. Taking the current time and the previous time as an example, the vehicle system can determine the signal strength difference between the two times based on the signal strength at the current time and the signal strength at the previous time, and can use this signal strength difference as the change in signal strength between the two times, so as to determine the user's movement trend based on the change in signal strength and determine whether the user's vehicle usage probability has increased.

[0048] S2222: In response to determining that the change in signal strength between the current time and the previous time is greater than zero, the vehicle is unlocked.

[0049] In this step: After the vehicle's infotainment system determines the change in signal strength between two time points, it determines whether the probability of the user using the vehicle has increased based on the change in signal strength. Specifically, the closer the key is to the vehicle, the stronger the signal strength the infotainment system receives from the key through its low-frequency antenna. If the infotainment system determines that the change in signal strength between the current time point and the previous time point is greater than zero, it indicates that the distance between the user and the vehicle has shortened, meaning the user is gradually approaching the vehicle, thus increasing the probability of using the vehicle and indicating a stronger user desire to use it. Once the vehicle has passed biometric verification, the infotainment system can control the vehicle to unlock, allowing the door to be opened directly when the user is near it, ensuring vehicle security while also meeting the user's needs.

[0050] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the process. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.

[0051] It should be noted that the above description describes some embodiments of this application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in a different order than that shown in the above embodiments and still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0052] Based on the same inventive concept, corresponding to any of the above-described embodiments, this application also provides an unlocking device.

[0053] refer to Figure 3 The unlocking device includes a confirmation module 11, a first response module 12, and a second response module 13. The confirmation module 11 is used to obtain the user's biometric information based on the user's operation request, store the obtained biometric information in a database, and compare the biometric information in the database with pre-authorized identification information. The first response module is used to determine whether the current mode is unlock mode or screen-off mode in response to the successful matching of the biometric information with the pre-authorized identification information, and then send the biometric information to the vehicle system for unlocking the vehicle. The second response module is used to format the database in response to the receipt of the biometric information by the vehicle system.

[0054] Specific participation Figure 3The unlocking device provided in this application can receive user operation requests through a confirmation module. After receiving the user's operation request, the control module can obtain the user's biometric information based on the user's operation request, and then store the obtained biometric information in the database. It can also compare the biometric information stored in the database with pre-authorized identification information and send the comparison result to the first response module. When the comparison result received by the first response module is that the biometric information matches the pre-authorized identification information successfully, the first response module determines the current mode of the mobile terminal. When the current mode of the mobile terminal is determined to be the unlock mode or screen-off mode, the first response module can send the biometric information to the vehicle system through wireless network or Bluetooth transmission, so that the vehicle system can initially unlock the vehicle. After receiving the biometric information, the vehicle system can send feedback information to the second response module. After receiving the feedback information, in order to prevent the biometric information stored in the mobile terminal from being leaked or maliciously stolen, the second response module can format the database to clear the sent biometric information, thereby improving the security of vehicle unlocking and locking.

[0055] Furthermore, based on the same inventive concept, corresponding to any of the above-described embodiments, this application also provides another unlocking device.

[0056] refer to Figure 4 The unlocking device includes a receiving module 21 and a control module 22. The receiving module is used to receive biometric information sent by the mobile terminal and compare the received biometric information with pre-authorized identification information. The control module is used to delete the received biometric information in response to determining that the biometric information matches the pre-authorized identification information, receive the key signal of the key through the vehicle's low-frequency antenna, and control the vehicle to unlock based on the received key signal.

[0057] For details, please refer to [link / reference]. Figure 4The unlocking device provided in this application can receive biometric information sent by a mobile terminal through a receiving module. After receiving the biometric information, the receiving module can perform a secondary comparison between the received biometric information and pre-authorized identification information, and then send the current comparison result to the control module. If the control module confirms that the biometric information received by the vehicle system matches the pre-authorized identification information, the control module can delete the received biometric information to reduce the risk of leakage of user biometric information by the vehicle system. At the same time, the control module can control the vehicle's low-frequency antenna to turn on, so as to receive the key signal of the key through the low-frequency antenna, and control the vehicle to unlock based on the received key signal. If the control module determines that the vehicle's low-frequency antenna does not receive the key signal of the key, it means that the user may have stopped using the vehicle or has not moved into the detection range of the low-frequency antenna. At this time, the vehicle can be kept locked to maintain the vehicle's security.
