Description

Technical Field

[0001] This application relates to the field of automotive anti-theft technology, specifically to a method, device, electronic device, and storage medium for unlocking a transmission system. Background Technology

[0002] Car anti-theft systems are designed to prevent unauthorized starting of the engine or other major power sources of a vehicle. In related technologies, this is typically achieved through steering mechanism locking systems or gear shift mechanism locking systems. However, with advancements in motor control technology, some new energy vehicles have eliminated gear shift mechanism locking systems. To optimize costs, steering mechanism locking systems are often also eliminated, and the vehicle's locking status is controlled by the locking state of the transmission system.

[0003] In related technologies, the electronic parking brake system is powered by the vehicle's small battery (usually a 12V storage battery). Even if the car key's anti-theft authentication fails, the user can connect the electronic parking brake system to the small battery by pressing the one-button start switch, and the small battery will then power the electronic parking brake system. At this time, if the user presses the brake pedal and presses the electronic parking brake release switch, the parking mechanism integrated into the rear brake will release.

[0004] In other words, as long as the user can enter the car and press the one-button start switch, the car's transmission system can be unlocked, rendering the transmission system incapable of anti-theft function.

[0005] It should be noted that the information disclosed in the background section of this application is intended only to enhance the understanding of the general background of this application, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] In view of this, this application provides a method, device, electronic device and storage medium for unlocking a transmission system, in order to solve the problem in the prior art that as long as the user can enter the car and press the one-button start switch, the transmission system of the car can be unlocked, thus rendering the transmission system without anti-theft function.

[0007] In a first aspect, embodiments of this application provide a transmission system unlocking method, applied to a vehicle controller, the method comprising:

[0008] Obtain key signal;

[0009] Determine whether the key signal matches the expected key signal, and obtain the matching result between the key signal and the expected key signal;

[0010] Based on the matching result between the key signal and the expected key signal, a matching status signal is sent to the electronic parking system.

[0011] In this embodiment, the vehicle controller determines whether the key signal matches the expected key signal, and sends a matching status signal to the electronic parking system based on the matching result. It is understood that if the key signal matches the expected key signal, the electronic parking system can unlock the transmission system; if the key signal does not match the expected key signal, unlocking the transmission system is not allowed, thereby preventing unauthorized movement of the vehicle and achieving the effect of car theft prevention.

[0012] In one possible implementation, sending a matching status signal to the electronic parking system based on the matching result of the key signal and the expected key signal includes:

[0013] If the key signal matches the expected key signal, a first matching status signal is sent to the electronic parking system;

[0014] If the key signal does not match the expected key signal, a second matching status signal is sent to the electronic parking system.

[0015] In this embodiment, if the vehicle controller determines that the key signal matches the expected key signal, it sends a first matching status signal to the electronic parking system. This first matching status signal indicates that the key signal matches the expected key signal. If the vehicle controller determines that the key signal does not match the expected key signal, it sends a second matching status signal to the electronic parking system. This second matching status signal indicates that the key signal does not match the expected key signal. By sending the matching status signal from the vehicle controller to the electronic parking system, the electronic parking system can respond in accordance with the key signal matching result, thereby preventing unauthorized movement of the vehicle by criminals.

[0016] In one possible implementation, sending the first matching status signal to the electronic parking system includes:

[0017] The system periodically sends a first matching status signal to the electronic parking system at preset time intervals.

[0018] If the electronic parking system lacks a memory function and the vehicle controller only sends the first matching status signal once, the user may need to restart the car to unlock it, impacting the user experience. Therefore, in this embodiment, after the vehicle controller determines that the key signal matches the expected key signal, it periodically sends the first matching status signal to the electronic parking system at preset time intervals. It can be understood that periodically sending the first matching status signal to the electronic parking system ensures that when the key signal matches, the user can unlock the vehicle at any time, guaranteeing a smooth user experience.

[0019] In one possible implementation, sending the second matching status signal to the electronic parking system includes:

[0020] The system periodically sends a second matching status signal to the electronic parking system at preset time intervals.

[0021] If the electronic parking brake system lacks a memory function and the vehicle controller only sends the second matching status signal once, the electronic parking brake system may be unable to confirm whether the current key signal matches the expected key signal when the user presses the release switch, resulting in an inability to respond promptly and accurately. Therefore, in this embodiment, after determining that the key signal does not match the expected key signal, the vehicle controller periodically sends a second matching status signal to the electronic parking brake system at preset time intervals. It can be understood that periodically sending the second matching status signal to the electronic parking brake system ensures that the system can confirm the matching status of the current key signal and the expected key signal in real time, thereby enabling a timely and accurate response.

[0022] In one possible implementation, prior to acquiring the key signal, the method further includes:

[0023] A third matching status signal is sent to the electronic parking system, the third matching status signal being used to indicate that the vehicle controller is powered on but has not acquired a key signal.

[0024] In this embodiment, before the vehicle controller acquires the key signal, a third matching status signal is sent to the electronic parking system to indicate that the vehicle controller is powered on but has not acquired the key signal. It can be understood that the vehicle controller uses the third matching status signal to indicate that it is powered on, so that the electronic parking system or other systems can obtain the power-on status of the vehicle controller.

[0025] Secondly, embodiments of this application provide a transmission system unlocking method applied to an electronic parking system, the method comprising:

[0026] Receive the matching status signal sent by the vehicle controller;

[0027] The locking state of the transmission system is adjusted according to the matching status signal sent by the vehicle controller.

[0028] In this embodiment, the electronic parking system adjusts the locking state of the transmission system based on the matching status signal sent by the vehicle controller. It can be understood that the matching status signal sent by the vehicle controller is a signal sent by the vehicle controller based on the matching result of the key signal. Therefore, the electronic parking system's response based on the matching status signal is more accurate and timely, improving the vehicle's response speed and enhancing the user experience.

[0029] In one possible implementation, adjusting the locking state of the transmission system based on the matching status signal sent by the vehicle controller includes:

[0030] If the matching status signal sent by the vehicle controller is the first matching status signal, then the transmission system is unlocked.

[0031] In this embodiment, if the matching status signal received by the electronic parking system is the first matching status signal, the transmission system is unlocked. If the matching status signal is not the first matching status signal, the electronic parking system will not allow the transmission system to be unlocked. In other words, unless the key signal matches the expected key signal, the electronic parking system will not allow the transmission system to be unlocked, thereby achieving the purpose of car anti-theft.

[0032] Thirdly, embodiments of this application provide a vehicle controller, including:

[0033] Key signal acquisition module, used to acquire key signals;

[0034] The judgment module is used to determine whether the key signal matches the expected key signal and to obtain the matching result between the key signal and the expected key signal;

[0035] The matching status signal sending module is used to send a matching status signal to the electronic parking system based on the matching result between the key signal and the expected key signal.

[0036] Fourthly, embodiments of this application provide an electronic parking system, including:

[0037] The matching status signal receiving module is used to receive the matching status signal sent by the vehicle controller;

[0038] The lock state adjustment module is used to adjust the lock state of the transmission system according to the matching state signal sent by the vehicle controller.

[0039] Fifthly, embodiments of this application provide a transmission system unlocking system, including:

[0040] The vehicle controller described in the third aspect;

[0041] The electronic parking system described in the fourth aspect.

[0042] In a sixth aspect, embodiments of this application provide a computer-readable storage medium including a stored program, wherein, when the program is executed, it controls the device where the computer-readable storage medium is located to perform the method described in either the first or second aspect.

[0043] It is understood that the vehicle controller provided in the first three aspects, the electronic parking system provided in the fourth aspect, the transmission system unlocking system provided in the fifth aspect, and the computer-readable storage medium provided in the sixth aspect are used to execute the method provided in this application. Therefore, the beneficial effects they can achieve can be referred to the beneficial effects in the corresponding methods, and will not be repeated here.

[0044] In this embodiment, the vehicle controller determines whether the key signal matches the expected key signal, and sends a matching status signal to the electronic parking system based on the matching result. It is understood that if the key signal matches the expected key signal, the electronic parking system can unlock the transmission system; if the key signal does not match the expected key signal, unlocking the transmission system is not allowed, thereby preventing unauthorized movement of the vehicle and achieving the effect of car theft prevention.

[0051] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0052] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0054] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0055] Car anti-theft systems are designed to prevent unauthorized starting of the engine or other major power sources of a vehicle. In related technologies, this is typically achieved through steering mechanism locking systems or gear shift mechanism locking systems. However, with advancements in motor control technology, some new energy vehicles have eliminated gear shift mechanism locking systems. To optimize costs, steering mechanism locking systems are often also eliminated, and the vehicle's locking status is controlled by the locking state of the transmission system.

[0056] In related technologies, the electronic parking brake system is powered by the vehicle's small battery (usually a 12V storage battery). Even if the car key's anti-theft authentication fails, the user can connect the electronic parking brake system to the small battery by pressing the one-button start switch, and the small battery will then power the electronic parking brake system. At this time, if the user presses the brake pedal and presses the electronic parking brake release switch, the parking mechanism integrated into the rear brake will release.

[0057] In other words, as long as the user can enter the car and press the one-button start switch, the car's transmission system can be unlocked, rendering the transmission system incapable of anti-theft function.

[0058] To address the aforementioned problems, this application provides a method for unlocking a transmission system. The method involves the vehicle controller determining whether the key signal matches the expected key signal, and sending a matching status signal to the electronic parking system based on the matching result. It is understood that if the key signal matches the expected key signal, the electronic parking system can unlock the transmission system; if the key signal does not match the expected key signal, unlocking the transmission system is not permitted, thereby preventing unauthorized movement of the vehicle and achieving the effect of vehicle anti-theft. A detailed description is provided below with reference to the accompanying drawings and specific embodiments.

[0059] The transmission system generally consists of a clutch, gearbox, universal joint, final drive, differential, and half-shafts. Its basic function is to transmit power from the engine to the drive wheels of the vehicle, generating driving force and enabling the vehicle to move at a certain speed. Of course, the transmission system can also be used to lock the vehicle, preventing unauthorized movement. Understandably, when the vehicle's transmission system is unlocked, the parking mechanism integrated into the rear brake is released, allowing the vehicle to move normally.

[0060] First, a method for unlocking a transmission system provided in the embodiments of this application will be described in detail.

[0061] See Figure 1 This is a flowchart illustrating a transmission system unlocking method provided in an embodiment of this application. Figure 1 As shown, it mainly includes the following steps.

[0062] Step S101: The vehicle controller acquires the key signal.

[0063] Specifically, after the vehicle controller is powered on, it acquires the key signal. This means that when a user enters the vehicle with the key, the key can send a key signal, which the vehicle controller can then acquire. It should be noted that the key signal can be a signal sent by the car key, a signal sent by a mobile phone or other terminal, or other similar signals. This application embodiment does not specifically limit the type of key signal.

[0064] In practical applications, the vehicle controller is typically not continuously powered. Instead, the vehicle is powered on only after the user presses the start switch. This means the vehicle controller only powers on after the user presses the start switch. Since the vehicle controller cannot acquire the key signal immediately upon power-on, it sends a third matching status signal to the electronic parking system for a short period after power-on. This third matching status signal indicates that the vehicle controller is powered on but has not acquired the key signal. This period of not acquiring the key signal is usually short, typically a few milliseconds, after which the vehicle controller begins acquiring the key signal. Therefore, the vehicle controller only needs to send the third matching status signal once. In one possible implementation, the third matching status signal is 0x0 (i.e., 0000). However, those skilled in the art can set the third matching status signal to other forms according to actual needs, and this application does not impose specific limitations on this. Although the electronic parking brake system does not need to perform any corresponding response operation after receiving the third matching status signal, in some possible implementations, the dashboard or other devices in the car may need the third matching status signal to perform subsequent steps. This is because the vehicle controller sends the third matching status signal to the electronic parking brake system through the Controller Area Network (CAN). Therefore, the dashboard or other devices in the car can receive the third matching status signal through the CAN network and then perform subsequent steps to ensure the normal operation of various vehicle functions.

[0065] Step S102: The vehicle controller determines whether the key signal matches the expected key signal and obtains the matching result of the key signal and the expected key signal.

[0066] Specifically, after the vehicle controller receives the key signal, it determines whether the key signal matches the expected key signal, thereby obtaining the matching result of the key signal and the expected key signal. As mentioned above, the key signal may be a signal emitted by the key carried by the user, a signal emitted by the user's mobile phone, or a signal emitted by the fingerprint unlocking system when the user unlocks with their fingerprint. Of course, the key signal may also be other types of signals, and this application embodiment does not impose specific limitations on this.

[0067] In one possible implementation, when a user enters the car legally, the corresponding device will send a key signal. At this time, after the user presses the one-button start switch, the vehicle controller is powered on and obtains the key signal. Then, the vehicle controller can obtain the result that the key signal matches the expected key signal by judging whether the key signal matches the expected key signal.

[0068] However, when criminals illegally enter the car and press the start button, the vehicle controller powers on and receives the key signal. Because the signal emitted by the device carried by the criminal does not match the expected key signal, the vehicle controller can determine that the key signal does not match the expected key signal. Of course, criminals may also enter the vehicle by prying open the door, so if the criminal does not carry electronic devices, the vehicle controller will still receive a result indicating that the key signal does not match the expected key signal because it cannot receive the key signal.

[0069] Step S103: The vehicle controller sends a matching status signal to the electronic parking system based on the matching result between the key signal and the expected key signal.

[0070] Specifically, if the key signal matches the expected key signal, the vehicle controller sends a first matching status signal to the electronic parking system; if the key signal does not match the expected key signal, the vehicle controller sends a second matching status signal to the electronic parking system. It can be understood that the first matching status signal indicates that the key signal matches the expected key signal, and the second matching status signal indicates that the key signal does not match the expected key signal.

[0071] In one possible implementation, the first matching status signal can be 0×2 (i.e., 0010), and the second matching status signal can be 0×1 (i.e., 0001). It is understood that when the key signal matches the expected key signal, the vehicle controller sends 0010 to the electronic parking system; when the key signal does not match the expected key signal, the vehicle controller sends 0001 to the electronic parking system. Of course, those skilled in the art can set the first and second matching status signals to other forms according to actual needs, and this application embodiment does not impose specific limitations on this.

[0072] In addition, the matching status signal of the vehicle controller also includes 0×3 (i.e. 0011), which is a reserved signal. If the vehicle controller needs to exchange other information with the electronic parking system in the future, other information can be carried through 0011.

[0073] In practical applications, if the vehicle controller only sends a single matching status signal to the electronic parking system after obtaining a match between the key signal and the expected key signal, a problem may arise where a normal user cannot unlock the vehicle when needed. This is because electronic parking systems typically lack a memory function. In one possible implementation, after a user enters the vehicle and presses the start switch, the vehicle controller powers on and immediately obtains the key signal. Since the key signal emitted by the user's key matches the expected key signal, the vehicle controller should send a first matching status signal to the electronic parking system. If the user presses the start switch but does not perform any further action, and the vehicle controller only sends the first matching status signal once, then when the user needs to unlock the drivetrain, the electronic parking system, lacking a memory function, will be unable to determine whether the current key signal matches the expected key signal. Therefore, the electronic parking system may need to send a confirmation message to the vehicle controller to confirm the match. Understandably, if the vehicle controller only sends the first matching status signal once, the electronic parking system may not be able to respond promptly and accurately, affecting the user experience.

[0074] To address this issue, in this embodiment, when the key signal matches the expected key signal, the vehicle controller periodically sends a first matching status signal to the electronic parking system at preset time intervals. Similarly, when the key signal does not match the expected key signal, the vehicle controller periodically sends a second matching status signal to the electronic parking system at preset time intervals. It is understood that even if the electronic parking system lacks a memory function, by having the vehicle controller periodically send matching status information to the electronic parking system at preset time intervals, the electronic parking system can determine the matching result between the key signal and the expected key signal in real time and perform corresponding response operations based on the result, thereby improving the response speed and accuracy of the electronic parking system. In one possible implementation, the preset time interval can be 10ms. Of course, those skilled in the art can set the time interval to other times according to actual needs, and this embodiment does not impose specific limitations on this.

[0075] Step S104: The electronic parking system adjusts the locking state of the transmission system according to the matching status signal sent by the vehicle controller.

[0076] Specifically, after receiving the matching status signal sent by the vehicle controller, the electronic parking system adjusts the locking state of the transmission system according to the matching status signal sent by the vehicle controller.

[0077] In one possible implementation, if the matching status signal sent by the vehicle controller is the first matching status signal, the electronic parking system unlocks the drivetrain. If the matching status signal sent by the vehicle controller is not the first matching status signal, the electronic parking system does not allow the drivetrain to be unlocked. In other words, regardless of whether the matching status signal sent by the vehicle controller is the second, third, or any other matching status signal, the electronic parking system does not allow the drivetrain to be unlocked.

[0078] If the vehicle controller sends a second matching status signal, it indicates that the key signal in the vehicle does not match the expected key signal or that no key signal is present. Obviously, the electronic parking brake system should not unlock the transmission system in this case. If the vehicle controller sends a third matching status signal, it means that the vehicle controller is only powered on but has not yet detected the key signal. In this case, whether it is a legitimate user or a criminal, as long as they can enter the vehicle and press the start switch, the vehicle controller can send a third matching status signal to the electronic parking brake system. If the electronic parking brake system receives the third matching status signal and unlocks the transmission system, the transmission system unlocking system will lose its anti-theft function.

[0079] In summary, the vehicle controller determines whether the key signal matches the expected key signal and sends a matching status signal to the electronic parking system based on the matching result. In other words, if the key signal matches the expected key signal, the electronic parking system can unlock the transmission system; if the key signal does not match the expected key signal, unlocking the transmission system is not allowed, thus preventing unauthorized vehicle movement and achieving the effect of car theft prevention.

[0080] Corresponding to the above embodiments, this application also provides a vehicle controller.

[0081] See Figure 2 This is a schematic diagram of the structure of a vehicle controller provided in an embodiment of this application. Figure 2 As shown, the vehicle controller may include a key signal acquisition module 201, a judgment module 202, and a matching status signal transmission module 203. These components communicate via one or more buses. Those skilled in the art will understand that the structure of the electronic device shown in the figure does not constitute a limitation on the embodiments of this application. It may be a bus topology or a star topology, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0082] Among them, the key signal acquisition module 201 is used to acquire key signals;

[0083] The judgment module 202 is used to judge whether the key signal matches the expected key signal, and to obtain the matching result of the key signal and the expected key signal;

[0084] The matching status signal sending module 203 is used to send a matching status signal to the electronic parking system based on the matching result between the key signal and the expected key signal.

[0085] In addition, corresponding to the above embodiments, this application also provides an electronic parking system.

[0086] See Figure 3 This is a schematic diagram of an electronic parking system provided in an embodiment of this application. Figure 3 As shown, the electronic parking system may include a matching status signal receiving module 301 and a lock status adjustment module 302. These components communicate via one or more buses. Those skilled in the art will understand that the structure of the electronic device shown in the figure does not constitute a limitation on the embodiments of this application. It may be a bus topology or a star topology, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0087] Among them, the matching status signal receiving module 301 is used to receive the matching status signal sent by the vehicle controller;

[0088] The locking state adjustment module 302 is used to adjust the locking state of the transmission system according to the matching state signal sent by the vehicle controller.

[0089] In addition, corresponding to the above embodiments, this application also provides a transmission system unlocking system.

[0090] See Figure 4 This is a schematic diagram of a transmission system unlocking system provided in an embodiment of this application. Figure 4 As shown, the transmission system unlocking system may include a vehicle controller 401 and an electronic parking system 402. These components communicate via one or more buses. Those skilled in the art will understand that the structure of the electronic devices shown in the figures does not constitute a limitation on the embodiments of this application. It may be a bus-shaped structure or a star-shaped structure, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0091] The vehicle controller 401 is used to acquire a key signal; determine whether the key signal matches a expected key signal, obtain a matching result between the key signal and the expected key signal; and send a matching status signal to the electronic parking system based on the matching result between the key signal and the expected key signal.

[0092] The electronic parking system 402 is used to receive a matching status signal sent by the vehicle controller; and to adjust the locking state of the transmission system according to the matching status signal sent by the vehicle controller.

[0093] Corresponding to the above embodiments, this application also provides a flowchart of another method for unlocking a transmission system.

[0094] See Figure 5 This is a flowchart illustrating another transmission system unlocking method provided in this application embodiment. This method can be applied to... Figure 4 The transmission system unlocking system shown mainly includes the following steps.

[0095] Step S501: The vehicle controller sends a matching status signal to the electronic parking system via the CAN network.

[0096] Step S502: The electronic parking system determines whether the matching status signal is the first matching status signal and whether it receives the brake pedal pressing signal and the electronic parking release signal.

[0097] Specifically, when a user needs to unlock the drivetrain, the user will press the brake pedal and press the electronic parking release switch. At this time, the brake pedal controller will send a brake pedal depress signal to the electronic parking system, and the electronic parking system will also receive an electronic parking release signal. The electronic parking system can only control the drivetrain to unlock when the user needs to unlock it. Therefore, when the electronic parking system determines that the matching status signal is the first matching status signal and receives the brake pedal depress signal and the electronic parking release signal, step S503 is executed; when the electronic parking system determines that the matching status signal is not the first matching status signal or does not receive the brake pedal depress signal and the electronic parking release signal, step S504 is executed.

[0098] Step S503: The electronic parking system unlocks the transmission system.

[0099] Specifically, after the electronic parking system releases the rear brake parking mechanism, it simultaneously sends a transmission system unlocking signal to the instrument panel controller, which then controls the parking status indicator light on the instrument panel to turn off.

[0100] Step S504: The electronic parking system does not allow the transmission system to be unlocked.

[0101] For specific details regarding the embodiments of this application, please refer to the above. Figure 1 The descriptions in the illustrated embodiments are omitted for brevity.

The storage medium may be a magnetic disk, optical disk, read-only memory (ROM), or random access memory (RAM), etc.
