[0043] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0045] In the related art, digital keys are, for example, Bluetooth keys or NFC keys. The Bluetooth key can unlock the door without contact and can even unlock the door without the user feeling it. The NFC key does not rely on battery power and is more reliable.

[0046] The Bluetooth key communicates with the vehicle's key control device through the Bluetooth channel to achieve key identification. The NFC key module communicates with the vehicle's NFC card reader through the NFC channel, and the NFC card reader communicates with the key control device to achieve key identification. It can be seen that the main control logic of digital keys such as Bluetooth keys or NFC keys is in the key control device. As an electronic control unit, the key control device will inevitably have hardware failures and control logic failures. When the key control device fails, the vehicle cannot be unlocked, affecting the normal use of the vehicle and providing a poor user experience.

[0047] The current solution is to add a dynamic key authentication module to detect the connection status of the key control device. If the key control device is abnormal, the key stored in the dynamic key authentication module is used to implement the unlocking function. This solution can effectively solve the unlocking problem when the key control device fails. However, the method of adding a dynamic key authentication module still has disadvantages. On the one hand, an additional dynamic key authentication module is required, which increases the corresponding cost. On the other hand, although the vehicle can be unlocked, because the key control device fails, the key control device still needs to be further repaired after unlocking to ensure normal driving use.

[0048] In order to solve the above problems, an embodiment of the present disclosure provides a method for unlocking a vehicle. Figure 1 This is a flow chart of a vehicle unlocking method provided by an embodiment of the present disclosure. This method can be executed by a vehicle unlocking device provided by an embodiment of the present disclosure. The vehicle unlocking method provided by an embodiment of the present disclosure can be applied to application scenarios where a vehicle needs to be unlocked. Figure 1 As shown, the method comprises the following steps:

[0049] S101 . Determine whether a key control device satisfies a first preset fault condition.

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

[0051] Figure 2 A schematic diagram of the structure of a vehicle provided in an embodiment of the present disclosure is shown in FIG. 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 a device such as an NFC card reader that can read the vehicle key information stored in the digital key 7. In the subsequent embodiments, the key information reading device 1 is described as an NFC card reader, and the subsequent embodiments are not repeated. The key control device 2 can be connected to the key information reading device 1 and the vehicle body control device 3 through a CAN bus, and the vehicle body control device 3 is connected to the door lock system 4 through a CAN bus.

[0053] Take the digital key 7 as an NFC key for example. The NFC key communicates with the key information reading device 1 through the NFC channel to identify the vehicle key, so that the key information reading device 1 obtains the vehicle key information. The vehicle key information may include key ID information and key information, for example. Each NFC key has a unique key ID information, which is used to unlock a vehicle. The key information may be information encrypted from the key ID information. After completing the key configuration process, the key control device 2 stores the key information in the NFC key to support the reading and use of the key information reading device 1 when performing the subsequent unlocking operation.

[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, 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 to unlock the vehicle.

[0055] If no feedback information indicating successful unlocking is received within the first preset time, it means that the vehicle is not unlocked normally, and an operation of determining whether the key control device meets a first preset fault condition is performed.

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

[0057] In some embodiments, the key control device will perform periodic self-tests. If an abnormality is found during the self-test, a corresponding diagnostic trouble code (DTC) will be generated. When the key information reading device performs message detection on the key control device, if a diagnostic trouble code of the key control device is detected, it is determined that the key control device has a fault.

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

[0059] In some other embodiments, it is also possible to determine that a key control device has failed by combining detection of a fault code of the key control device and detection of abnormal message data fed back by the key control device to the key information reading device, which is not limited in the embodiments of the present disclosure.

[0060] S102 : In response to the key control device meeting a first preset fault condition, controlling the key control device to restart.

[0061] Specifically, after determining that the key control device meets the preset fault condition, the key control device can be controlled to restart. The restart of the key control device can solve the software failure caused by the system operation problem of the key control device itself, so that the key control device can restore the unlocking function.

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

[0063] For example, 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 dotted line in the figure shows the wiring harness used to connect the key information reading device 1 and the key control device 2. 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 failure of the unlocking logic caused by the system operation problem of the key control device 2 itself, thereby improving the user experience.

[0064] S103: Determine whether the restarted key control device can send an unlocking instruction to the vehicle body control device.

[0065] Optionally, determining whether the restarted key control device is capable of sending an unlocking command to the body control device comprises: controlling the key control device to send an unlocking command to the body control device after a second preset time after the key control device is restarted; and determining that the restarted key control device fails to send an unlocking command to the body control device based on not receiving feedback information of successful unlocking 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, for example, 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 restores the unlocking function after restarting, the key control device performs a key information verification. After the verification passes, the body control device performs a security authentication and sends an unlocking command to the body control device. The body control device controls the door lock system to complete subsequent unlocking actions to unlock the vehicle.

[0067] If no feedback information indicating successful unlocking is received within the third preset time, it means that the key control device does not restore the unlocking function after restarting, and the restarted key control device fails to send an unlocking instruction to the vehicle body control device.

[0068] Optionally, controlling the key information reading device to send an unlocking command to the body control device to unlock the vehicle includes: obtaining 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; in response to the second vehicle key information stored in the key information reading device matching the first vehicle key information, controlling the key information reading device to send an unlocking command to the body control device to unlock the vehicle.

[0069] Exemplarily, the key information reading device can 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 body control device, and the body control device controls the door lock system based on the unlocking command to complete the subsequent unlocking action to unlock the vehicle.

[0070] Optionally, after controlling the key information reading device to send an unlocking instruction to the vehicle body control device, it also includes: controlling the vehicle body control device to determine whether the key control device meets a second preset fault condition; in response to the key control device meeting the second preset fault condition, controlling the vehicle body control device to unlock the vehicle.

[0071] Specifically, since the key ID information in the key information reading device has not been encrypted, the security level of the unlocking command sent by the key information reading device to the body control device is lower than the security level of the unlocking command sent by the key control device to the body control device. In order to improve the security level of vehicle unlocking, the body control device needs to determine whether a fault has occurred in the key control device based on the unlocking command sent by the key information reading device before controlling the vehicle to unlock, so as to determine whether the key control device is still faulty after restart and cannot send an unlocking command to the body control device, thereby improving the security level of vehicle unlocking.

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

[0073] Specifically, after the body control device receives the unlocking command sent by the key information reading device, it detects the communication status of the key control device. Based on the detected fault code of the key control device and / or the detected abnormal message data fed back by the key control device to the body control device, it determines that the key control device is faulty. The body control device skips the security check 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 reading device, thereby unlocking the vehicle.

[0074] Optionally, after determining that the key control device meets a preset fault condition, the method further includes: generating prompt information of a key control device fault.

[0075] Specifically, to ensure driving safety and a continuous good car-using experience, if a key control device is determined to be faulty, after solving the user's need to unlock the vehicle, the body control device can limit the vehicle's high-voltage starting to improve the safety of vehicle use.

[0076] Figure 2 In the figure, it is shown that the body control device 3 is electrically connected to the infotainment host 5, and the infotainment host 5 is electrically connected to the central control display screen 6. The body control device 3 sends a prompt message of the key control device 2 failure to the infotainment host 5, such as the vehicle computer, and for example, a prompt message such as "the key control device is faulty" can be displayed on the central control display screen. In addition, the vehicle user can also be reminded by voice broadcast, such as playing "the key control device is faulty" or other sentences with similar semantics, or by honking the horn to remind the vehicle user that the key control device is faulty.

[0077] Therefore, it is convenient for the user to find the fault of the key control device in time, so that the user can further repair the key control device in a targeted manner.

[0078] A vehicle unlocking method provided by an embodiment of the present disclosure solves software failures caused by system operation problems of the key control device itself by controlling the key control device to restart, so that the key control device can restore the unlocking function. If the key control device after restart still cannot send an unlocking command to the body control device, the key information reading device is controlled to send an unlocking command to the body control device to unlock the vehicle, thereby solving the problem that the vehicle cannot be unlocked normally when the key control device fails, improving the reliability of vehicle unlocking, improving user experience, and eliminating the need to add an additional control module in the vehicle to realize the unlocking function, thereby reducing the cost of the vehicle.

[0079] The disclosed embodiment also provides a vehicle unlocking device.
