Technical Field

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

[0002] With the development of vehicle technology, in recent years, especially in new energy vehicles, digital keys have gradually replaced traditional mechanical keys as the unlocking method, and are becoming the mainstream unlocking method for vehicles.

[0003] In related technologies, the main control logic of digital keys, such as Bluetooth keys or NFC (Near Field Communication) keys, resides in the key control device. This means that the vehicle is unlocked through communication between the digital key and the key control device. As an electronic control unit, the key control device is inevitably susceptible to hardware failures and control logic malfunctions. When the key control device malfunctions, it cannot transmit key information or perform related logic processing, resulting in unlocking failure, impacting normal vehicle use, and leading to a poor user experience. Summary of the Invention

[0004] To address the aforementioned technical issues, this disclosure provides a vehicle unlocking method, unlocking device, and vehicle, which improves vehicle unlocking reliability, enhances user experience, and reduces vehicle costs.

[0005] In a first aspect, this disclosure provides a method for unlocking a vehicle, the vehicle including a key information reading device, a key control device, and a vehicle body control device;

[0006] The unlocking method includes:

[0007] Determine whether the key control device meets the first preset fault condition;

[0008] In response to the key control device meeting the first preset fault condition, the key control device is controlled to restart;

[0009] Determine whether the key control device after restarting can send an unlock command to the vehicle control device;

[0010] In response to the failure of the key control device to send an unlock command to the body control device after a restart, the key information reading device is controlled to send an unlock command to the body control device to unlock the vehicle.

[0011] Optionally, the first preset fault condition includes at least one of: detecting a fault code of the key control device and detecting abnormal message data fed back by the key control device to the key information reading device.

[0012] Optionally, before determining whether the key control device meets the first preset fault condition, the method further includes:

[0013] The key control device sends an unlock command to the vehicle control device;

[0014] Determine whether a successful unlocking notification is received within the first preset time period;

[0015] If no successful unlocking feedback is received within a first preset time, the system performs an operation to determine whether the key control device meets the first preset fault condition.

[0016] Optionally, determining whether the key control device can send an unlock command to the vehicle control device after restarting includes:

[0017] After a second preset time following the restart of the key control device, the key control device is controlled to send an unlock command to the vehicle control device;

[0018] Based on the fact that no successful unlocking feedback was received within the third preset time, it was determined that the key control device failed to send an unlocking command to the vehicle control device after restarting.

[0019] Optionally, the step of controlling the key information reading device to send an unlock command to the vehicle control device to unlock the vehicle includes:

[0020] Obtain the first vehicle key information sent by the vehicle key;

[0021] Determine whether the second vehicle key information stored in the key information reading device matches the first vehicle key information;

[0022] In response to the second vehicle key information stored in the key information reading device matching the first vehicle key information, the key information reading device is controlled to send an unlocking command to the vehicle control device to unlock the vehicle.

[0023] Optionally, after controlling the key information reading device to send an unlock command to the vehicle control device, the method further includes:

[0024] The vehicle control device determines whether the key control device meets preset fault conditions.

[0025] In response to the key control device meeting a second preset fault condition, the vehicle body control device is controlled to unlock the vehicle.

[0026] Optionally, the second preset fault condition includes at least one of: detecting a fault code of the key control device and detecting abnormal message data fed back by the key control device to the body control device.

[0027] Secondly, this disclosure also provides a vehicle unlocking device, comprising:

[0028] The fault diagnosis module is used to determine whether the key control device meets the first preset fault condition;

[0029] The restart control module, in response to the key control device meeting the first preset fault condition, controls the key control device to restart;

[0030] The instruction sending and judging module determines whether the key control device after restarting can send an unlocking instruction to the vehicle control device;

[0031] The unlocking control module, in response to the key control device failing to send an unlocking command to the body control device after a restart, controls the key information reading device to send an unlocking command to the body control device, thereby unlocking the vehicle.

[0032] Thirdly, this disclosure also provides a computer-readable storage medium that stores a program or instructions; the program or instructions cause a computer to perform the steps of the method as described in the first aspect.

[0033] Fourthly, this disclosure also provides a vehicle including a processor and a memory, wherein the processor executes the steps of the method described in the first aspect by invoking a program or instructions stored in the memory.

[0034] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0035] This disclosure provides a vehicle unlocking method, unlocking device, and vehicle. The vehicle includes a key information reading device, a key control device, and a vehicle body control device. The vehicle unlocking method includes: determining whether the key control device meets a first preset fault condition; responding to the key control device meeting the first preset fault condition, controlling the key control device to restart; determining whether the restarted key control device can send an unlocking command to the vehicle body control device; responding to the restarted key control device failing to send an unlocking command to the vehicle body control device, controlling the key information reading device to send an unlocking command to the vehicle body control device, thereby unlocking the vehicle. Thus, by controlling the restart of the key control device, software faults caused by system operation problems of the key control device itself are resolved, allowing the key control device to restore its unlocking function. Even if the restarted key control device still cannot send an unlocking command to the vehicle body control device, controlling the key information reading device to send an unlocking command to the vehicle body control device unlocks the vehicle. This solves the problem of the vehicle being unable to unlock normally when the key control device malfunctions, improves the reliability of vehicle unlocking, enhances the user experience, and eliminates the need for an additional control module in the vehicle to implement the unlocking function, reducing vehicle costs. Attached Figure Description

[0036] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

[0037] To more clearly illustrate the technical solutions in the embodiments of this disclosure or the prior art, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0039] Figure 2 This is a schematic diagram of the structure of a vehicle provided in an embodiment of the present disclosure;

[0040] Figure 3 A schematic diagram of the structure of a vehicle unlocking device provided in an embodiment of this disclosure;

[0041] Figure 4 This is a schematic diagram of the structure of a vehicle provided in an embodiment of the present disclosure.

[0042] The components include: 1. Key information reading device; 2. Key control device; 3. Body control device; 4. Door lock system; 5. Infotainment host; 6. Central control display screen; and 7. Digital key. Detailed Implementation

[0043] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0044] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0045] In related technologies, digital keys are, for example, Bluetooth keys or NFC keys. Bluetooth keys can unlock and lock without contact, and can even unlock and lock without the user's notice. NFC keys do not rely on battery power and are more reliable.

[0046] Bluetooth keys communicate with the vehicle's key control device via a Bluetooth channel to achieve key recognition. NFC key modules communicate with the vehicle's NFC reader via an NFC channel, and the NFC reader communicates with the key control device to achieve key recognition. It is evident that the main control logic of digital keys such as Bluetooth or NFC keys resides in the key control device. As an electronic control unit, the key control device is inevitably susceptible to hardware failures and control logic malfunctions. When the key control device fails, the vehicle cannot be unlocked, affecting normal vehicle use and resulting in a poor user experience.

[0047] The current solution involves adding a dynamic key authentication module to detect the connection status of the key control device. If the key control device malfunctions, the unlocking function is achieved using the key stored in the dynamic key authentication module. This solution can effectively solve the unlocking and locking problem when the key control device fails. However, adding a dynamic key authentication module still has drawbacks. On the one hand, it requires an additional dynamic key authentication module, increasing the corresponding cost. On the other hand, although the vehicle can be unlocked, the key control device still needs further repair after unlocking to ensure normal driving use.

[0048] To address the aforementioned problems, this disclosure provides a method for unlocking a vehicle. Figure 1 This is a flowchart illustrating a vehicle unlocking method provided in an embodiment of this disclosure. This method can be executed by the vehicle unlocking device provided in this embodiment, and the vehicle unlocking method provided in this embodiment is applicable to application scenarios where vehicles need to be unlocked. Figure 1 As shown, the method includes the following steps:

[0049] S101. Determine whether the key control device meets the first preset fault condition.

[0050] Optionally, before determining whether the key control device meets the first preset fault condition, the method further includes: controlling the key control device to send an unlocking command to the vehicle control device; determining whether a successful unlocking feedback message is received within a first preset time; and, in response to not receiving a successful unlocking feedback message within the first preset time, performing the operation of determining whether the key control device meets the first preset fault condition.

[0051] Figure 2 This is a schematic diagram of the structure of a vehicle provided in an embodiment of the present disclosure, such as... Figure 2 As shown, the vehicle includes a key information reading device 1, a key control device 2, and a body control device 3; the key control device 2 is electrically connected to the key information reading device 1 and the body control device 3 respectively, and the body control device 3 is electrically connected to the key information reading device 1.

[0052] For example, the key information reading device 1 can be an NFC card reader or other device capable of reading vehicle key information stored in the digital key 7. In subsequent embodiments, the key information reading device 1 will be described as an NFC card reader, and will not be repeated in subsequent embodiments. The key control device 2 can, for example, communicate with the key information reading device 1 and the body control device 3 via a CAN bus. The body control device 3 and the door lock system 4 are also connected via a CAN bus.

[0053] Taking digital key 7 as an example of an NFC key, the NFC key communicates with key information reader 1 through the NFC channel to recognize the vehicle key, thereby enabling key information reader 1 to obtain vehicle key information. Vehicle key information may include, for example, key ID information and key information. Each NFC key has a unique key ID information used to unlock a specific vehicle. The key information may be, for example, information obtained by encrypting the key ID information. After completing the key configuration process, key control device 2 stores the key information in the NFC key, supporting subsequent unlocking operations by key information reader 1.

[0054] When the key control device 2 is working normally, the key information reading device 1 sends the key information to the key control device 2. The key control device 2 verifies the key information. After the verification is successful, it performs security authentication with the body control device 3 and sends the unlocking command to the body control device 3. The body control device 3 controls the door lock system 4 to complete the subsequent unlocking action, thereby unlocking the vehicle.

[0055] If no successful unlocking feedback is received within the first preset time, it indicates that the vehicle has not been unlocked normally, and the operation of judging whether the key control device meets the first preset fault condition will be performed.

[0056] Optionally, the first preset fault condition includes at least one of: detecting a fault code of the key control device and detecting abnormal message data fed back by the key control device to the key information reading device.

[0057] In some embodiments, the key control device performs periodic self-tests. If an anomaly is detected during the self-test, a corresponding Diagnostic Trouble Code (DTC) is generated. When the key information reading device performs message detection on the key control device, if it detects the DTC, it determines that the key control device has malfunctioned.

[0058] In other embodiments, when the key information reading device performs message detection on the key control device, if it detects abnormal message data fed back by the key control device, it indicates that the communication between the key control device and the key information reading device is abnormal, and thus it is determined that the key control device has malfunctioned.

[0059] In some other embodiments, a fault in the key control device can be determined by combining the detection of a fault code in the key control device with the detection of abnormal message data fed back by the key control device to the key information reading device. This disclosure does not limit this approach.

[0060] S102. In response to the key control device meeting the first preset fault condition, the key control device is restarted.

[0061] Specifically, after determining that the key control device meets the preset fault conditions, the key control device can be restarted. Restarting the key control device can resolve software faults caused by system operation problems of the key control device itself, so as to restore the unlocking function of the key control device.

[0062] Optionally, restarting the key control device includes: controlling the sending of a voltage signal to the key control device to restart the key control device.

[0063] For example, such as Figure 2 As shown, the key control device 2 and the key information reading device 1 can be directly connected via a wiring harness. Figure 2 The wiring harness connecting the key information reading device 1 and the key control device 2 is shown in dashed lines. The key information reading device 1 sends a voltage signal to the key control device 2 through the wiring harness to control the key control device 2 to power off and restart. The restart of the key control device 2 solves the problem of the unlocking logic failure caused by the system operation problem of the key control device 2 itself, thus improving the user experience.

[0064] S103. Determine whether the key control device after restarting can send an unlock command to the vehicle control device.

[0065] Optionally, determining whether the restarted key control device can send an unlock command to the body control device includes: controlling the key control device to send an unlock command to the body control device after a second preset time following the restart of the key control device; and determining that the restarted key control device failed to send an unlock command to the body control device based on the fact that no successful unlocking feedback information was received within a third preset time.

[0066] Specifically, after the key control device restarts and waits for, for example, a second preset time (which may be the time required for the key control device to restart), the key information reading device resends the key information to the key control device. If the key control device resumes its unlocking function after restarting, the key control device verifies the key information. After successful verification, the vehicle control device performs security authentication and sends an unlocking command to the vehicle control device. The vehicle control device then controls the door lock system to complete the subsequent unlocking action to unlock the vehicle.

[0067] If no successful unlocking feedback is received within the third preset time, it indicates that the key control device has not restored the unlocking function after restarting, and the key control device failed to send an unlocking command to the vehicle control device after restarting.

[0068] Optionally, controlling the key information reading device to send an unlocking command to the vehicle control device to unlock the vehicle includes: acquiring first vehicle key information sent by the vehicle key; determining whether second vehicle key information stored in the key information reading device matches the first vehicle key information; and in response to the matching of the second vehicle key information stored in the key information reading device with the first vehicle key information, controlling the key information reading device to send an unlocking command to the vehicle control device to unlock the vehicle.

[0069] For example, the key information reading device may pre-store key ID information as the second vehicle key information, obtain the first vehicle key information sent by the vehicle key, and match the second vehicle key information with the first vehicle key information. If the match is successful, the key information reading device is controlled to send an unlocking command to the vehicle control device. The vehicle control device controls the door lock system to complete the subsequent unlocking action based on the unlocking command, thereby unlocking the vehicle.

[0070] Optionally, after the key information reading device sends an unlocking command to the vehicle control device, the method further includes: controlling the vehicle control device to determine whether the key control device meets a second preset fault condition; and in response to the key control device meeting the second preset fault condition, controlling the vehicle control device to unlock the vehicle.

[0071] Specifically, because the key ID information in the key information reader is not encrypted, the security level of the unlocking command sent by the key information reader to the vehicle control device is lower than the security level of the unlocking command sent by the key control device to the vehicle control device. In order to improve the security level of vehicle unlocking, the vehicle control device needs to determine whether the key control device has malfunctioned before controlling the vehicle to unlock, based on the unlocking command sent by the key information reader. This ensures that the key control device still has a malfunction after restarting and cannot send an unlocking command to the vehicle control device, thereby improving the security level of vehicle unlocking.

[0072] Optionally, the second preset fault condition includes at least one of: detecting a fault code of the key control device and detecting abnormal message data fed back from the key control device to the body control device.

[0073] Specifically, after receiving the unlocking command sent by the key information reader, the body control device checks the communication status of the key control device. If a fault code of the key control device is detected, and / or an abnormal message data is detected from the key control device to the body control device, the key control device is determined to be faulty. The body control device skips the security verification with the key control device and controls the door lock system to complete the subsequent unlocking action based on the unlocking command sent by the key information reader, thereby unlocking the vehicle.

[0074] Optionally, after determining that the key control device meets the preset fault conditions, the method further includes: generating a fault message for the key control device.

[0075] Specifically, to ensure driving safety and a consistently good user experience, if a malfunction is detected in the key control device, after addressing the user's need to unlock the vehicle, the body control device can limit the high-voltage starting of the vehicle to improve the safety of vehicle use.

[0076] Figure 2 The diagram exemplarily illustrates an electrical connection between the body control unit 3 and the infotainment host 5, and an electrical connection between the infotainment host 5 and the central control display screen 6. The body control unit 3 sends a malfunction message about the key control unit 2 to the infotainment host 5, such as the vehicle's infotainment system, for example, displaying a message such as "Key control unit malfunction" on the central control display screen. Alternatively, the malfunction can be addressed through voice announcements, such as playing a message like "Key control unit malfunction" or similar phrases, or by using a horn or other similar means.

[0077] This allows users to promptly identify malfunctions in the key control device, enabling them to perform targeted repairs.

[0078] The vehicle unlocking method provided in this disclosure solves software malfunctions caused by system operation problems of the key control device by restarting the key control device, thereby restoring the unlocking function of the key control device. If the key control device still cannot send an unlocking command to the vehicle body control device after restarting, the key information reading device is controlled to send an unlocking command to the vehicle body control device, thus unlocking the vehicle. This solves the problem of the vehicle being unable to unlock normally when the key control device malfunctions, improves the reliability of vehicle unlocking, enhances the user experience, and eliminates the need to add an additional control module to the vehicle to achieve the unlocking function, thereby reducing the cost of the vehicle.
