[0060] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0061] In this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function. It should be understood that there is no logical or temporal dependency between "first," "second," and "nth," nor are there any restrictions on quantity or execution order.

[0062] In this application, the term "at least one" means one or more, and "multiple" means two or more.

[0063] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, data stored, data displayed, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0064] The following is a brief introduction to the terminology used in this application.

[0065] Passive Entry Passive Start (PEPS): This is a keyless entry and start system that can automatically sense the key and control the vehicle to unlock or start.

[0066] Remote Keyless Entry (RKE): A device that enables remote locking and unlocking of a vehicle via wireless radio frequency signals.

[0067] Body Control Module (BCM): A component used to coordinate and control the electrical equipment of the vehicle body (such as door locks, lights, etc.).

[0068] Instrument Cluster Module (ICM): A component that controls the information displayed on the vehicle's instrument cluster.

[0069] In-Vehicle Head Unit (IHU): This is the main unit that integrates multiple functions such as audio playback, video display, Bluetooth connection, and navigation positioning, and can drive speakers to emit sound.

[0070] Central locking: The vehicle's central control door locks can centrally control the locking and unlocking of all four doors.

[0071] Arming and disarming: Arming refers to activating the vehicle's anti-theft mode, while disarming refers to deactivating the vehicle's anti-theft mode, allowing the door to be opened normally.

[0072] Figure 1 This is a schematic diagram of a vehicle door superlock control system provided in an embodiment of this application. See also... Figure 1 The system 100 includes a passive entry start controller 101, a body controller 102, a superlock controller 103, and a door superlock 104. That is, the various controllers are connected to each other through an on-board wired network to form a superlock control system.

[0073] In some embodiments, the remote key communicates with the passive entry and start controller 101 via a wireless radio frequency signal; the passive entry and start controller 101 is connected to the body controller 102 via an in-vehicle wired network; the superlock controller 103 is connected to the body controller 102 via an in-vehicle wired network; and the door superlock 104 and the superlock controller 103 are connected via a common wiring harness, together forming an actuator. The in-vehicle wired network refers to the communication lines inside the vehicle, such as a Controller Area Network (CAN) bus or a Local Interconnect Network (LIN) bus, used for data transmission and communication between various electronic control units.

[0074] The passive entry start controller 101 receives the radio frequency signal sent by the remote key and generates instructions. Specifically, after detecting a user request for the superlock function, the passive entry start controller 101 sends a corresponding signal to the body controller 102. The body controller 102 receives instructions and controls the central locking system, manages the vehicle anti-theft mode, and sends superlock control instructions, such as controlling the central locking system to lock or unlock, or to activate or deactivate the vehicle anti-theft mode (i.e., arm or disarm). Superlock control instructions may include at least one of a superlock locking instruction and a superlock unlocking instruction. The superlock controller 103 responds to the superlock control instructions to drive the door superlock 104 to perform locking or unlocking actions. The actuator, composed of the door superlock 104 and the superlock controller 103, performs the locking, unlocking, and status detection of the door superlock. Optionally, the key controller in system 100 detects whether the user requests the superlock to lock or unlock via the remote key using radio frequency, and also serves to wake up the network.

[0075] In some embodiments, system 100 further includes an instrument panel and an in-vehicle multimedia host. The instrument panel and the in-vehicle multimedia host are respectively connected to the body controller 102 via a wired in-vehicle network. The instrument panel and the in-vehicle multimedia host are used to perform visual and audible prompts to inform the user of the superlock function status, such as whether the superlock is locked or unlocked. More specifically, after the body controller 102 recognizes that the preconditions for the superlock are met and receives the superlock control command from the passive entry start controller 101, it sends a signal to the instrument panel to indicate the superlock function status and to the in-vehicle multimedia host to drive the speaker to implement an in-vehicle alarm. For example, the preconditions include the vehicle being stationary, the vehicle power being off, and all doors being closed.

[0076] Figure 2 This is a flowchart illustrating a control method for a vehicle door superlock according to an embodiment of this application. This method is executed by the control system of the aforementioned vehicle door superlock. See also... Figure 2 The method includes the following steps:

[0077] 201. The passive entry start controller receives the locking signal sent by the remote key.

[0078] In this embodiment, the passive entry start controller and the remote key communicate via wireless radio frequency signals. When the lock button on the remote key is pressed, the remote key sends a wireless radio frequency lock signal, which is received by the passive entry start controller.

[0079] In some embodiments, the superlock control locking logic is executed under certain preconditions. For example, the preconditions are that the vehicle power is off and all four doors, the hood, and the trunk lid are closed. Here, the vehicle power is off, meaning the power state KeySts = OFF, such as when the ignition switch is not inserted or when the electronic key is not activated.

[0080] In some embodiments, based on the passive entry activation controller, the system receives locking signals sent by the remote key a predetermined number of times within a first predetermined time period. This application embodiment does not limit the first predetermined time period or the predetermined number of times; for example, the first predetermined time period may be 2 seconds or 3 seconds, and the predetermined number of times may be two or three. This further defines the reception conditions of the locking signal, effectively preventing erroneous locking caused by misoperation or external interference signals. Only signals meeting the specific time and number of times requirements are recognized by the system, improving the accuracy and security of the super lock system triggering and reducing inconvenience caused to users by unnecessary misoperation.

[0081] For example, after the vehicle remote key is pressed twice within 2 seconds (i.e., Double Click Lock), it passively enters the start controller to receive the remote key signal and send the remote key lock signal (such as RKE LOCK) and the super lock status signal (such as RKE Search Car) to the body controller.

[0082] 202. Based on the locking signal, the vehicle body controller drives the central locking system to perform the locking action and activates the vehicle anti-theft mode.

[0083] In this embodiment of the application, after receiving the locking signal, the body controller first locks and arms the central locking system, and sends a signal indicating that the driver's side door lock status is locked (such as Drive Door LockSts).

[0084] 203. After the vehicle anti-theft mode has been activated and delayed for the second preset time, the vehicle body controller sends a super lock locking command to the super lock controller.

[0085] In this embodiment, the second preset duration is not limited, such as being set to 200 milliseconds or 400 milliseconds. For example, after successful arming, the vehicle controller sends a super lock locking command (such as Super Lock Cmd) to the super lock controller after a 200-millisecond delay.

[0086] Steps 202 to 203 above are an exemplary method in which the body controller sends a superlock locking command to the superlock controller based on the locking signal. This method clarifies the step-by-step response logic after receiving the locking signal: first, the body controller drives the central locking system to lock and arm; after arming is completed and a second preset time delay is applied, the superlock locking command is then sent. This step-by-step operation with a delay avoids mechanical interference that may occur when the central locking system and superlock operate simultaneously, ensuring that the two locks work stably in sequence, improving system reliability, and enhancing vehicle safety.

[0087] 204. The superlock controller responds to the superlock locking command and drives the door superlock to perform the locking action.

[0088] In this embodiment of the application, after receiving the superlock locking command, the superlock controller drives the superlock to lock.

[0089] In some embodiments, after the superlock locks the vehicle doors, the instrument panel controller and the in-vehicle multimedia host in the system drive the instrument panel to perform a visual prompt and the speakers to perform an audible prompt. For example, after receiving the superlock lock command, the instrument panel controller forwards an alarm signal (such as a warning signal) to the in-vehicle multimedia host through the internal protocol of the instrument panel controller and the in-vehicle multimedia host, so that the in-vehicle multimedia host can trigger an in-vehicle audible alarm (such as an acoustic warning) to remind the user. This provides timely and intuitive feedback to the user that the superlock has been successfully locked, avoiding repeated operations due to uncertainty about the locking status and improving the user experience. In addition, the audible and visual prompts also serve as a warning to some extent, enhancing the anti-theft effect of the vehicle and further ensuring vehicle security.

[0090] In other words, when the user double-clicks the lock button on the remote key to send a superlock signal, the passive entry start controller wakes up the vehicle and transmits a superlock locking command. Upon receiving the superlock locking command, the body controller sends the command to the superlock controller to lock the doors. Simultaneously, visual and audible alerts are emitted via network signals from the instrument panel and speakers to provide in-vehicle notification. These steps complete the superlock locking process. More specifically, the locking logic sequence is: user presses button, passive entry start controller transmits signal, body controller locks central locking first, superlock locking command is sent after a delay, and superlock action and audible / visual alerts are provided. That is, the central locking is locked first, then the superlock is locked, which conforms to the mechanical locking sequence requirements.

[0091] For ease of description, see Figure 3 As shown, Figure 3 This is a schematic diagram illustrating a locking process according to an embodiment of this application. After the vehicle remote key is pressed twice within 2 seconds to perform the locking operation, the system passively enters the start controller to receive the remote key signal and sends a remote key locking signal and a superlock status signal to the body controller. Upon receiving the locking signal, the body controller first locks and armes the central locking system and sends a driver's side door lock status signal. After successful arming, after a 200-millisecond delay, the body controller sends a superlock locking command to the superlock controller. Upon receiving the superlock locking command, the superlock controller activates the superlock. Upon receiving the superlock locking command, the instrument panel controller forwards an alarm signal to the in-vehicle multimedia host, enabling the in-vehicle multimedia host to issue an in-vehicle audible alarm to remind the user.

[0092] For ease of description, see Figure 4 As shown, Figure 4This is a schematic diagram illustrating an interaction principle in an embodiment of this application. The body domain module includes a body controller, a passive entry / start controller, and a central gateway (CGW). Based on the above interaction, the body controller sends instruction source information (such as Information Source Order Information) to the central gateway and receives superlock commands and driver's side door lock status. The passive entry / start controller sends instruction source information to the central gateway and receives driver's side door lock status.

[0093] In some embodiments, after the vehicle is armed normally, the super lock needs to be engaged. The user needs to press the remote key twice within 2 seconds to perform the above steps 201 to 204. These steps will not be described in detail here.

[0094] In some embodiments, a four-way twin-cell relay and a control chip are used to control the superlock circuit output of each door lock and detect the superlock status through circuit signals, which will not be elaborated further here.

[0095] This application provides a control method for a vehicle door superlock, introducing an independent superlock controller and reusing components such as the passive entry start controller and the body controller. In this configuration, if one component fails, the other modules can still work collaboratively. Based on low cost and functional reuse, this method improves overall safety redundancy, achieves a highly secure superlock function, and enhances the user experience. Furthermore, based on the superlock implementation, the superlock motor can be controlled independently, enabling reuse for multiple functions such as an electronic child lock.

[0096] Having described the locking steps for the superlock above, the unlocking steps for the superlock will now be further explained below. Figure 5 This is a flowchart of another control method for a vehicle door superlock provided in an embodiment of this application. This method is executed by the control system of the aforementioned vehicle door superlock. See also... Figure 5 The method includes the following steps:

[0097] 501. When the door superlock is locked, the unlock signal is received by the passive entry start controller.

[0098] In this application embodiment, various communication methods are supported for triggering vehicle unlocking, including Passive Entry (PE), Remote Keyless Entry (RKE), Near Field Communication Access (Near Access), Bluetooth Low Energy (BLE), and Remote Start. This application does not limit or elaborate on these methods. For example, in any of the above scenarios, the Passive Entry / Start controller sends an unlock signal (e.g., Unlock) to the vehicle body controller.

[0099] It should be noted that when the superlock is engaged, the mechanical key unlocks the superlock and central locking automatically through the lock mechanism.

[0100] 502. Based on the unlock signal, the body controller sends a super lock unlock command to the super lock controller.

[0101] In this embodiment, the vehicle body controller sends a super lock unlock command (such as Super Lock CmdUnlock) to the super lock controller.

[0102] 503. The superlock controller responds to the superlock unlock command and drives the door superlock to perform the unlocking action.

[0103] In this embodiment of the application, after receiving the superlock unlock command, the superlock controller drives the superlock to unlock.

[0104] 504. After sending the super lock unlock command and delaying for the third preset time, the vehicle body controller deactivates the vehicle anti-theft mode and drives the central locking system to perform the unlocking action.

[0105] In this embodiment, the third preset duration is not limited; for example, it can be set to 200 milliseconds or 400 milliseconds. For instance, the central locking system unlocks after a 200-millisecond delay following the sending of the superlock unlock command. This delay further ensures the security of the unlocking process, providing the system with sufficient time for status confirmation and data processing, thus avoiding potential security risks caused by rapid unlocking. Simultaneously, the delay sequence with the superlock unlock conforms to the unlocking requirements of the mechanical structure, ensuring the stability and reliability of the entire unlocking process and improving the safety and stability of vehicle use.

[0106] In other words, when the user presses the unlock button on the remote key, the passive entry start controller wakes up the vehicle and transmits a superlock unlock command. Upon receiving the superlock unlock command, the body controller sends it to the superlock controller to unlock the doors, thus completing the superlock unlocking process. More specifically, the unlocking logic sequence is: user triggers unlocking, passive entry start controller transmits a signal, body controller unlocks the superlock first, and then the central locking system unlocks after a delay. This conforms to the mechanical locking sequence requirements.

[0107] For ease of description, an example unlocking process is given. The passive entry / start controller sends an unlock signal to the body control controller. Upon receiving the unlock signal from the passive entry / start controller, the body control controller sends a superlock unlock command to the superlock controller. After a 200-millisecond delay, the body control controller disarms the system and unlocks the central locking system. Upon receiving the superlock unlock command, the superlock controller activates the superlock to unlock.

[0108] In some embodiments, after the central locking system performs the unlocking action, the instrument panel is driven to perform a visual prompt action and the speaker is driven to perform an audible prompt action through the instrument panel controller and the in-vehicle multimedia host in the system, thereby intuitively prompting the user that the lock has been successfully unlocked. The prompting principle is the same as in the above embodiments, and will not be described again here.

[0109] This application provides a control method for a vehicle door superlock, introducing an independent superlock controller and reusing components such as a passive entry start controller and a body controller. In this configuration, if one component fails, the other modules can still work collaboratively. Based on low cost and functional reuse, this method improves overall safety redundancy, achieving a highly secure superlock function and enhancing the user experience. Furthermore, this approach allows the superlock to be safely and conveniently disengaged when the vehicle needs to be entered, ensuring both safety and user convenience while achieving a balance between security and convenience.

[0113] The first drive module 603 is used by the superlock controller to drive the door superlock to perform the locking action in response to the superlock locking command.

[0114] In some embodiments, the sending module 602 is further configured to drive the central locking system to perform a locking action based on the locking signal and activate the vehicle anti-theft mode; after the vehicle anti-theft mode has been activated and a second preset time has elapsed, the body controller sends a super lock locking command to the super lock controller.

[0119] The receiving module 601 is also used to receive the unlock signal based on the passive entry start controller;
