Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted combination lock technology, and more specifically, to a control method, domain controller, and system for a vehicle-mounted combination lock. Background Technology

[0002] As people's living standards improve, they are becoming more aware of and demanding of personal privacy. Many car models are now equipped with in-car password boxes to store personal belongings.

[0003] While existing in-vehicle keypad locks are placed inside the vehicle, their control systems are independent of the vehicle's infotainment system, increasing research and development costs as well as control costs. Furthermore, users need to enter a password on the control panel to unlock them, which is inconvenient and lacks security.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a control method, domain controller, and system for an in-vehicle password box. By interacting with the VIU (Vehicle Information Unit), the encryption, decryption, unlocking, and locking of the in-vehicle password box are controlled, improving operational flexibility and security. Furthermore, the domain controller controls the in-vehicle password box, achieving integration between the in-vehicle password box and the vehicle's infotainment system, thus reducing costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a method for controlling a vehicle-mounted combination lock, comprising:

[0008] Acquire the setting signal used to control the vehicle's keypad lock;

[0009] Based on the set signal, a target operation type for the vehicle-mounted keypad is determined; the target operation type includes at least one of encrypting, decrypting, unlocking, and locking the vehicle-mounted keypad.

[0010] The service interface on the vehicle information unit (VIU) corresponding to the target operation type is invoked, so that the VIU responds to the invocation operation of the service interface and drives the on-board password box to perform the target operation; the service interface includes at least one of encryption service interface, decryption service interface, unlocking service interface and locking service interface.

[0011] In a second aspect, the present invention provides a domain controller, comprising:

[0012] At least one processor, and a memory communicatively connected to at least one of the processors;

[0013] The memory stores instructions executable by at least one of the processors, which, when executed by at least one of the processors, enable the at least one of the processors to perform any of the control methods for the vehicle-mounted keypad.

[0014] Thirdly, the present invention provides a control system for an in-vehicle password box, comprising: a domain controller and a vehicle information unit (VIU) connected in communication;

[0015] The domain controller executes any of the control methods described for the vehicle-mounted keypad;

[0016] The VIU is used to respond to the domain controller's call to the service interface and drive the vehicle password box to perform the target operation;

[0017] The target operation includes at least one of encryption, decryption, unlocking, and locking.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention controls the encryption, decryption, unlocking and locking of the vehicle password box through the interaction between the domain controller and the VIU, so that the user no longer needs to manually enter the password on the vehicle password box, which improves the flexibility of operation and enhances the user experience; controlling the vehicle password box through the domain controller instead of the user directly operating the vehicle password box also improves the security of the vehicle password box.

[0020] (2) The present invention uses a domain controller to control the encryption, decryption, unlocking and locking of the vehicle password box, eliminating the need for a separate control system for the vehicle password box. This achieves the integration of the vehicle password box and the vehicle machine, which helps to reduce R&D and control costs.

[0021] (3) The present invention realizes the signal transmission between the domain controller and the VIU through the service interface call, which increases the security of the transmitted signal. At the same time, encapsulating the function into a service interface during programming can simplify the code and reduce the development burden. Attached Figure Description

[0029] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0030] Example 1

[0031] Figure 1 This is a schematic diagram of the control system for an in-vehicle password box provided in this embodiment. The system includes a domain controller and a Vehicle Information Unit (VIU) connected by communication. Optionally, the domain controller can be a Smart Cockpit Domain Controller (CDC). The method provided in this embodiment will be described below using the CDC as an example.

[0032] The vehicle-mounted keypad requires five input / output ports (I / O ports) to respond to control commands sent by the VIU and to provide feedback on the keypad's status. See Table 1 for the five signal names, signal types, valid levels, and I / O ports.

[0033] Table 1 Interface Information for Vehicle Password Confiscation Box

[0034]

[0035] In Table 1, DI represents digital input signal, and H-bridge represents the signal type of DC motor control circuit.

[0036] See Figure 1The locking mechanism of the vehicle's combination lock is hardwired to the VIU's interface; this hardwire is used for power supply and signal transmission. The VIU primarily drives the unlocking and locking of the combination lock, and receives status signals from the door and lock. The VIU connects to the CDC via Ethernet (ETH). The CDC is used for encrypting and decrypting the combination lock, receiving password input from the vehicle's screen, comparing passwords, and calling the VIU's service interface to perform corresponding operations based on the comparison results. Optional, see [link to relevant documentation]. Figure 1 The system also includes a Telematics Box (T-BOX) to provide a notification when the vehicle's keypad lock door is not closed. The installation location of this system within the vehicle depends on the specific requirements of the vehicle and is not limited to any particular location.

[0037] Optionally, the CDC also communicates with a portable mobile terminal (e.g., a mobile phone), which performs the same functions as the in-vehicle screen. The following embodiments use an in-vehicle screen as an example, but are also applicable to portable mobile terminals. For example, the CDC obtains the user's input password and facial image for the in-vehicle keypad from the portable mobile terminal, and uses this information to encrypt, decrypt, unlock, and lock the in-vehicle keypad.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0039] (1) The present invention controls the encryption, decryption, unlocking and locking of the vehicle password box through the interaction between the domain controller and the VIU, so that the user no longer needs to manually enter the password on the vehicle password box, which improves the flexibility of operation and enhances the user experience; controlling the vehicle password box through the domain controller instead of the user directly operating the vehicle password box also improves the security of the vehicle password box.

[0040] (2) The present invention uses a domain controller to control the encryption, decryption, unlocking and locking of the vehicle password box, eliminating the need for a separate control system for the vehicle password box. This achieves the integration of the vehicle password box and the vehicle machine, which helps to reduce R&D and control costs.

[0041] Example 2

[0042] Figure 2 This is a flowchart illustrating a control method for a vehicle-mounted combination lock according to an embodiment of the present invention. This method is applicable to situations involving the control of a vehicle-mounted combination lock. See also... Figure 2 and combined Figure 1 The control system for the vehicle-mounted keypad shown in this embodiment includes the following methods:

[0043] S110, Obtain the setting signal used to control the vehicle's password box.

[0044] The setting signal is a signal used to control the vehicle-mounted keypad to perform the target operation. This embodiment does not limit the content of the setting signal.

[0045] S120. Determine the target operation type for the vehicle-mounted keypad according to the set signal.

[0046] The target operation type includes at least one of encrypting, decrypting, unlocking, and locking the vehicle-mounted keypad.

[0047] Optionally, the CDC preset logic determines the unlocking, locking, encryption, and decryption operations for the vehicle's combination lock based on the set signals. To ensure system security, in this embodiment, the CDC does not directly drive the vehicle's combination lock. Instead, the VIU connects to the five I / O ports of the vehicle's combination lock to transmit high and low level signals to drive the combination lock to perform the corresponding target operations.

[0048] In this embodiment, the code driving the target operation in the VIU is pre-encapsulated as a service interface, including at least one of an unlock service interface, a lock service interface, an encryption service interface, and a decryption service interface. Since the VIU and CDC are different controllers, the CDC's call to the service interface in the VIU is actually a cross-domain service call.

[0049] S130. Call the service interface on the vehicle information unit (VIU) corresponding to the target operation type, so that the vehicle information unit (VIU) responds to the call operation of the service interface and drives the vehicle password box to perform the target operation.

[0050] After CDC calls any service interface, VIU responds to CDC's call to that service interface and drives the vehicle keypad to perform unlocking, locking, encryption, or decryption operations.

[0051] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0052] (1) The present invention controls the encryption, decryption, unlocking and locking of the vehicle password box through the interaction between the domain controller and the VIU, so that the user no longer needs to manually enter the password on the vehicle password box, which improves the flexibility of operation and enhances the user experience; controlling the vehicle password box through the domain controller instead of the user directly operating the vehicle password box also improves the security of the vehicle password box.

[0053] (2) The present invention uses a domain controller to control the encryption, decryption, unlocking and locking of the vehicle password box, eliminating the need for a separate control system for the vehicle password box. This achieves the integration of the vehicle password box and the vehicle machine, which helps to reduce R&D and control costs.

[0054] (3) The present invention realizes the signal transmission between the domain controller and the VIU through the service interface call, which increases the security of the transmitted signal. At the same time, encapsulating the function into a service interface during programming can simplify the code and reduce the development burden.

[0055] Example 3

[0056] This embodiment refines the automatic unlocking scheme for the vehicle-mounted keypad based on the above embodiments. Specifically, according to the set signal, the target operation type for the vehicle-mounted keypad is determined, including: obtaining the unlocking mode of the vehicle-mounted keypad and obtaining the corresponding set signal according to the unlocking mode; if the set signal meets the set conditions, controlling the vehicle's Driver Monitoring System (DMS) to identify the user's identity; if the user's identity is the vehicle owner, determining the target operation type as unlocking. The set signal includes at least one of the following: a key signal, a wireless communication signal connected to the vehicle's infotainment system, a vehicle location signal, and a current time signal.

[0057] Multiple unlocking modes are pre-set on the in-vehicle screen, including key unlocking, communication unlocking, location unlocking, and time unlocking. Users can select at least one unlocking mode to control the unlocking of the in-vehicle keypad. The CDC obtains the user-selected unlocking mode through the in-vehicle screen and retrieves the corresponding setting signal based on the unlocking mode. Specifically, key unlocking mode corresponds to the key signal, communication unlocking mode corresponds to the wireless communication signal connected to the vehicle's infotainment system, location unlocking mode corresponds to the vehicle's location signal, and time unlocking mode corresponds to the current time signal (obtainable from the vehicle's infotainment system). The setting signal must meet the set conditions, including the key signal being authenticated by the vehicle owner, the wireless communication signal connected to the vehicle's infotainment system being a set name, the vehicle being located within a set geographical range, and the current time signal being within a set time period. The CDC identifies the user based on the connected driver monitoring system. If the user is the vehicle owner (i.e., the user has passed owner authentication), the target operation type is determined to be unlocking. The unlocking service interface on the VIU is invoked, thereby the VIU drives the in-vehicle keypad to unlock, and the motor switch button of the in-vehicle keypad is opened.

[0058] The automatic unlocking scheme provided in this embodiment will be illustrated through several specific examples below.

[0059] 1. Key unlocking mode: After the key signal is authenticated by the owner, the vehicle's driver monitoring system identifies the user as the owner. When the owner is in the driver's seat, the vehicle's combination lock can be automatically unlocked. The combination lock can be opened by pressing a switch button. The combination lock is usually installed near the driver's seat for the owner's convenience in storing and retrieving items.

[0060] 2. Communication Unlock Mode: Users can set the vehicle's keypad lock to automatically unlock when connected to a specific Wi-Fi network via the "Lock" option in the vehicle's intelligent system settings. Multiple signal names can be set, making it easy to determine whether the vehicle system will automatically connect to the specified Wi-Fi network in a home garage or company garage. Then, based on the vehicle's driver monitoring system, the system will identify the user as the owner, and the keypad lock will be automatically unlocked when the owner is in the driver's seat.

[0061] 3. Location-Based Unlock Mode: Ensure the vehicle's location function is enabled and can receive location signals normally; the owner can save the current location signal. To ensure unlocking efficiency, the geographical range for automatic unlocking is typically defined as the latitude and longitude of a location plus a radius (R). R can be set by the user, usually 10, 50, 100 meters, etc. After the user sets it, the vehicle can automatically unlock the in-vehicle keypad after the owner authenticates upon entering the area.

[0062] 4. Time-based unlock mode: Car owners can set a preset time period. During this time period, after user authentication by the car owner, the vehicle's keypad lock will automatically unlock. After the time period expires, the keypad lock will automatically lock. The vehicle's keypad lock control system obtains the current time via the T-BOX and compares it with the set time period. If the comparison is successful, the lock will unlock; otherwise, it will remain locked.

[0063] In some situations, the vehicle owner may not need to unlock the vehicle's keypad lock after entering the vehicle, making it necessary to capture the owner's usage needs. Specifically, if the user is the vehicle owner, the domain controller identifies the user's location inside the vehicle, which can be determined using the in-vehicle camera. If the vehicle's keypad lock is located within a predetermined range (e.g., 0.5 meters) of the driver's seat, the domain controller determines the target operation type for that keypad lock to be unlocking when it detects the user's presence in the driver's seat. In other words, if the owner sits down and there is a keypad lock nearby, it indicates a need to unlock, and the unlocking operation is performed. Conversely, no operation is performed on keypad locks not located within the predetermined range of the driver's seat. If the keypad locks are located in different positions inside the vehicle, the domain controller selects the nearest target keypad lock based on the user's position and determines the target operation type for that target keypad lock to be unlocking. For example, if there is a keypad lock next to the driver's seat and another keypad lock in the back seat, the owner sitting in the back seat will be closest to the rear keypad lock and will attempt to unlock it.

[0064] This embodiment can determine whether the user intends to operate the combination lock by detecting whether the user is in the driver's seat; by unlocking the combination lock closest to the user, the user can operate it conveniently.

[0065] Optionally, in addition to the automatic unlocking method described above, password or facial recognition can also be used for unlocking. Specifically, the setting signal here includes an unlock command signal. Based on the setting signal, the target operation type for the vehicle's keypad is determined, including: controlling the vehicle's driver monitoring system to identify the user's identity, or responding to the key signal to perform owner authentication; if the user's identity is that of the owner or the key signal passes owner authentication, in response to the user-triggered unlock command signal, obtaining the vehicle keypad password or facial image entered by the user on the vehicle's screen; if the password or facial image passes authentication, the target operation type is determined to be unlocking; if the user's identity is not that of the owner and the key signal fails owner authentication, in response to the user-triggered unlock command signal, obtaining the vehicle keypad password entered by the user on the vehicle's screen; if the password passes authentication, the target operation type is determined to be unlocking.

[0066] Figure 3 This is a schematic diagram of the unlocking operation provided in an embodiment of the present invention. Taking the domain controller as a CDC as an example, the method includes the following operations:

[0067] S300, Start, then execute S310 and S320 respectively.

[0068] S310, Pass vehicle owner authentication. This specifically includes the user's identity being verified as the vehicle owner or the key signal passing vehicle owner authentication.

[0069] S311. Click "Unlock" on the vehicle screen to generate an unlock command signal.

[0070] S312. Compare the entered password with the original password to see if they match, and check if the facial recognition result belongs to the vehicle owner. If yes, unlocking is successful; otherwise, unlocking fails.

[0071] S313, Unlock successful. Then CDC calls VIU's unlock service interface, and VIU drives the vehicle's keypad lock to unlock.

[0072] S314, Unlock failed.

[0073] S320, Owner authentication failed. This specifically includes situations where the user is not the owner of the vehicle and the key signal has not been authenticated by the owner.

[0074] S321. Click "Unlock" on the vehicle screen to generate an unlock command signal.

[0075] S322. Compare the entered password with the original password. If they match, the unlock is successful; otherwise, the unlock fails.

[0076] S323, Unlock successful. Then CDC calls VIU's unlock service interface, and VIU drives the vehicle's keypad lock to unlock.

[0077] S334, Unlock failed.

[0078] After the user is authenticated as the vehicle owner, clicking "Unlock" on the in-vehicle screen generates an unlock command signal. The screen displays options to enter a password or a facial image, as well as the location of the vehicle's keypad lock inside the vehicle. The user can choose to enter either a password or a facial image. The CDC (Controlled Detection and Retrieval) system compares the entered password with the original password (i.e., the password set when encrypting the keypad lock) and verifies if the facial recognition result belongs to the vehicle owner. If the password matches or the facial image belongs to the vehicle owner, the keypad lock unlocks successfully; if the password does not match and the facial image does not belong to the vehicle owner, unlocking fails, and a failure message is displayed on the in-vehicle screen. When the user is not authenticated as the vehicle owner, clicking "Unlock" on the screen allows only password input. The CDC compares the entered password with the original password. If the password matches, unlocking succeeds; if the password does not match, unlocking fails, and a failure message is displayed on the in-vehicle screen.

[0079] Optionally, if unlocking fails, a pop-up window can prompt the user to re-enter the password, and the CDC will continue the comparison operation. The user can re-enter the password a maximum of a specified number of times (e.g., 5 times). After exceeding the specified number of times, the user will be prompted to wait for a certain period of time (e.g., 1 minute) before entering the password again, and facial recognition will be disabled for unlocking during this period. After the password is entered correctly, the CDC calls the unlocking service interface to unlock the vehicle's keypad.

[0080] This embodiment provides both vehicle owners and non-vehicle owners with facial recognition or password unlocking methods, increasing the diversity of unlocking options.

[0081] Example 4

[0082] Based on the above embodiments, this invention provides an automatic locking scheme after unlocking.

[0083] This embodiment also provides a locking operation after the vehicle-mounted keypad is unlocked. Specifically, based on a set signal, the target operation type for the vehicle-mounted keypad is determined, including: when the vehicle-mounted keypad is in the unlocked state, if the set signal is detected to not meet the set conditions, the target operation type is determined to be locking. The set signal includes at least one of the following: a wireless communication signal connected to the vehicle's infotainment system, a vehicle positioning signal, a current time signal, and a current vehicle speed signal. Based on this, the automatic locking method provided in this embodiment specifically includes at least one of the following, described using CDC as the executing entity:

[0084] 1. Communication Locking Method: When the vehicle's keypad is unlocked, the system detects the wireless communication signal automatically connected to the vehicle's infotainment system, such as Wi-Fi; if the Wi-Fi is not a pre-stored Wi-Fi with a specific name, the system automatically locks.

[0085] 2. Location-based locking method: When the vehicle key box is in the unlocked state, the vehicle location signal is detected; if the vehicle is not within the geographical range for automatic unlocking, the lock will automatically lock.

[0086] 3. Time-based locking method: When the vehicle-mounted keypad is in the unlocked state, the current time signal is detected; if the current time is not within the predetermined common time period, the lock will automatically lock.

[0087] 4. Speed-based locking method: When the vehicle keypad is unlocked, the current vehicle speed signal is detected. If the current vehicle speed signal is greater than a set value, the lock will automatically lock. The set value can be preset, for example, 20 km / h. When the CDC receives a current vehicle speed signal from the speed sensor that is less than or equal to the set value, it will not respond. When the current vehicle speed is greater than the set value, it indicates that the vehicle speed is too high and the locking service interface needs to be called, causing the VIU to drive the vehicle keypad to lock.

[0088] Optionally, in some cases, the vehicle owner may leave the vehicle after the keypad lock is unlocked. To prevent the loss of valuables, an automatic unlocking security monitoring strategy is implemented. Specifically, based on a set signal (including a user identity signal), the target operation type for the keypad lock is determined, including: real-time monitoring of the user's identity when the keypad lock is unlocked; if the monitored user identity signal changes from the owner's identity signal to a non-owner's identity signal, and the target operation type is determined to be locking, the locking service interface of the VIU is invoked to drive the keypad lock to automatically lock. In a specific implementation, the owner signal "owner" is first set. The driver monitoring system uses the vehicle's camera to monitor in real-time whether the user in the vehicle is the owner. When the user is identified as the owner through facial recognition technology, the driver monitoring system sends "owner=1" to the CDC; otherwise, it sends "owner=0". When the CDC receives "owner=1", the automatic unlocking function is maintained. When the driver monitoring system detects "owner=1" and then the driver leaves, and another person re-enters, the identity of this person needs to be identified in real-time. If the person is not identified as the owner, "owner=0" is immediately sent. After receiving owner=0, the CDC disables the automatic unlocking function and locks the vehicle's keypad lock, requiring a password to be entered on the vehicle's screen to unlock it.

[0089] In addition to the domain controller actively controlling the locking of the vehicle's keypad, the VIU can also actively perform timeout locking and door closing locking, as detailed in the following scheme:

[0090] 1. Timeout Locking: The VIU detects the door and lock status of the vehicle keypad. If the vehicle keypad is unlocked and closed after a first set time, the VIU drives the vehicle keypad to lock. For example, after the user is authenticated by the vehicle owner, the vehicle keypad function is activated. After the vehicle keypad is successfully unlocked, the VIU drives the keypad motor to unlock the keypad door, which takes T1ms. Then, after waiting for T2ms (e.g., 10ms), the door and lock status of the vehicle keypad are detected. At this time, the first set time is started: if the door is not opened after 30 seconds, the VIU drives the vehicle keypad motor to lock the keypad door.

[0091] 2. Door closing and locking: When the VIU detects that the vehicle password box door changes from open to closed, that is, the user actively closes the door, it will drive the vehicle password box to lock.

[0092] This embodiment provides solutions such as timeout locking, door closing locking, and automatic locking while driving. In particular, it automatically locks when the vehicle speed is high to prevent items from falling out; it also ensures that the vehicle's combination lock is closed when the user does not need it, thus protecting the safety of property and personnel.

[0093] Example 5

[0094] This embodiment refines the encryption and decryption operations of the vehicle-mounted password box based on the above embodiment.

[0095] Optionally, the setting signal includes an encryption command signal; based on the setting signal, the target operation type for the vehicle keypad is determined, including: controlling the vehicle's driver monitoring system to identify the user's identity, or responding to a key signal to perform owner authentication; if the user's identity is the owner or the key signal passes owner authentication, in response to the encryption command signal triggered by the user, the password for the vehicle keypad entered by the user on the vehicle screen is obtained; the target operation type is determined to be encryption. The domain controller calls the encryption service interface of the VIU to drive the vehicle keypad to encrypt.

[0096] Figure 4 This is a schematic diagram of the encryption operation of the vehicle-mounted password box provided in an embodiment of the present invention. Taking the domain controller as a CDC as an example, the method includes the following operations:

[0097] S400, Start. Execute S410 or S420 respectively.

[0098] S410, Pass vehicle owner authentication. This specifically includes the user's identity being verified as the vehicle owner or the key signal passing vehicle owner authentication.

[0099] The UsageMode signal, authenticated by the vehicle owner, is used by the driver monitoring system connected to the CDC to identify whether the user is the vehicle owner. If the user is identified as the owner, the system sends UsageMode=Convenience to the CDC. At this point, the function to encrypt the in-vehicle keypad is activated. By default, it is initially unencrypted, and the in-vehicle keypad is essentially a storage box. A password input box is then displayed on the vehicle's screen.

[0100] S411. The user sets a password on the vehicle screen, triggering an encryption command signal.

[0101] Specifically, users need to click the option to set a password on the in-vehicle screen and enter the same password multiple times in the pop-up input box before the password can be set successfully. If it fails, the user will be prompted to set it again.

[0102] Optionally, when the user clicks the option to set a password, the CDC will check the status of the vehicle's password locker. If the encryption status and password stored in the CDC are inconsistent with the encryption status and password stored in the VIU, the user will be prompted that the password locker settings are abnormal and that the encryption should be canceled before resetting the password.

[0103] S412, CDC obtains the password for the vehicle keypad entered by the user on the vehicle screen, and determines the target operation type of the vehicle keypad as encryption based on the password.

[0104] After obtaining the password, the CDC stores it in an electrically erasable programmable read-only memory (E2PROM), and at the same time, the vehicle screen displays a message indicating that the password box has been successfully encrypted.

[0105] S413 and VIU respond to the CDC's call to the encryption service interface, set the status of the vehicle keypad to encrypted, and drive the vehicle keypad to lock.

[0106] The CDC calls the VIU's service interface `setEncryptionStatus.CS_TrueFalse =True`, passing the successful encryption status of the combination lock to the VIU. The VIU then locks the combination lock, taking T1ms. After waiting for T2ms (e.g., 10ms), it checks the door and lock status of the combination lock.

[0107] S414 and VIU detect whether the vehicle's keypad lock is closed and locked. If the door is not closed, the user is prompted to close it, and S414 is executed again. If the door is closed and locked, the operation ends.

[0108] VIU will only lock the vehicle's keypad lock when it detects that the door is closed.

[0109] S415, prompt the user to close the door.

[0110] S416, End operation.

[0111] S420, Owner authentication failed. This specifically includes situations where the user is not the owner and the key signal has been authenticated by the owner. Encryption settings are not supported; proceed to S416.

[0112] Optionally, after the vehicle owner is authenticated, the user can change the password by selecting the password change button on the in-vehicle screen. The CDC will store the new password in the E2PROM and display a message on the in-vehicle screen indicating that the password change was successful.

[0113] This embodiment uses the CDC to call the VIU encryption service interface, allowing users to encrypt the vehicle keypad after being authenticated by the vehicle owner, thus improving the security and flexibility of the password settings.

[0114] Optionally, the setting signal includes a decryption command signal; based on the setting signal, the target operation type for the vehicle keypad is determined, including: controlling the vehicle's driver monitoring system to identify the user's identity, or responding to a key signal for owner authentication; if the user's identity is the owner or the key signal passes owner authentication, in response to the user-triggered decryption command signal, the target operation type is determined to be decryption. The domain controller calls the VIU's decryption service interface to drive the vehicle keypad to decrypt. Further, the VIU sets the vehicle keypad's state to decryption and drives the vehicle keypad to unlock.

[0115] Figure 5 This is a schematic diagram of the vehicle-mounted password lock decryption operation provided in an embodiment of the present invention. Taking the domain controller as a CDC as an example, the method includes the following operations:

[0116] S500, Start. Execute S510 or S520 respectively.

[0117] S510, Pass vehicle owner authentication. This specifically includes the user's identity being verified as the vehicle owner or the key signal passing vehicle owner authentication.

[0118] This embodiment can authenticate the vehicle owner using facial recognition or key signals.

[0119] S511: When the user cancels the encryption settings on the vehicle screen, a decryption command signal is triggered.

[0120] After the vehicle owner is authenticated, the option to cancel the encryption setting is displayed on the vehicle screen. When the user clicks the option, a decryption command signal is triggered to the CDC. The CDC determines that the target operation type of the vehicle keypad is decryption and calls the VIU decryption service interface.

[0121] S512. Verify if the user is the vehicle owner. If yes, proceed to S513; otherwise, proceed to S514.

[0122] To enhance security, the user's identity is verified again at this point to prevent unauthorized individuals from performing decryption operations.

[0123] Specifically, facial images are captured by the vehicle's camera and compared with pre-stored images of the vehicle owner's face in the CDC. If the images match, the verification is successful; otherwise, the verification fails and the operation ends.

[0124] S513 and VIU respond to the CDC's call to the decryption service interface, set the status of the vehicle password box to the decrypted state, and drive the vehicle password box to unlock.

[0125] The CDC calls the VIU's decryption service interface setEncryptionStatus CS_TrueFalse =False, passing the successful decryption status of the password box to the VIU; at the same time, the vehicle screen displays a message indicating that the password box function has been canceled.

[0126] The VIU sets the current combination lock to decryption mode and stores the decryption status in the E2PROM. The VIU then unlocks the vehicle combination lock, taking T1ms. After waiting for T2ms (e.g., 10ms), it checks the door and lock status of the vehicle combination lock.

[0127] S514, End operation.

[0128] S520, Owner authentication failed. This specifically includes situations where the user is not the owner and the key signal has been authenticated by the owner. Decryption settings are not supported; proceed to S514.

[0129] This embodiment allows users to decrypt the vehicle keypad after being authenticated by the vehicle owner by calling the decryption service interface of the VIU through the domain controller, thereby improving the security and flexibility of password settings.

[0130] Example 6

[0131] This embodiment, based on the above embodiments, refines the visualization and reminder schemes for the status of the vehicle-mounted keypad after the target operation. Specifically, after calling the service interface corresponding to the target operation type on the vehicle information unit (VIU) to enable the VIU to respond to the call to the service interface and drive the vehicle-mounted keypad to perform the target operation, it also includes at least one of the following operations:

[0132] 1. The VIU detects the door and lock status of the vehicle-mounted combination lock; controls the speaker to emit a prompt tone indicating the door and lock status, and / or displays the door and lock status on the vehicle screen. Specifically, after the VIU unlocks the combination lock, it waits for T2ms, detects the door and lock status, and reports them to the CDC. The CDC transmits the door and lock status to the display module of the vehicle screen, displaying the open / closed and unlocked / locked status of the combination lock in the status bar of the vehicle screen via icons. This allows the user to see the specific status of the combination lock on the screen. Furthermore, the CDC controls the speaker to emit a prompt tone indicating that the combination lock has been successfully unlocked, thus improving the user experience.

[0133] 2. In response to the signal sent by the VIU that the vehicle key box has not been closed within the time limit, remind the user to close the door based on the signal that the key box has not been closed within the time limit.

[0134] Specifically, the VIU detects that the vehicle key box door has remained open for a second set time, such as 2 minutes, and sends a signal to the CDC indicating that it has not been closed within the time limit. The CDC then reminds the user to close the door based on the signal, for example, by displaying "Please close the key box" on the vehicle screen.

[0135] 3. When the vehicle is locked and powered off and no one is inside, check whether the vehicle keypad is locked; if the vehicle keypad is not locked, report the unlocked signal to the intelligent digital vehicle platform, so that the intelligent digital vehicle platform sends the unlocked signal to the T-BOX, and reminds the user to close the door through the T-BOX.

[0136] Specifically, after the vehicle is powered off and no one is present, the vehicle's T-BOX receives the open / closed status of the in-vehicle keypad from the Intelligent Digital Vehicle Platform (IDVP) and reminds the user to close the door. IDVP continuously monitors the occupancy signals of the seats and the door status signals. When the occupancy signal is 0, it indicates no one is present. It also monitors the door status from the inside open to the closed state, timing this process (e.g., 10 seconds) to determine that the vehicle is unoccupied. When the vehicle is locked and powered off, the CDC reports the signal that the in-vehicle keypad is not closed to IDVP, which then transmits this information to the user's mobile phone via the in-vehicle T-BOX to remind them to close the door.
