[0067] Figure 4 This is a structural block diagram of a vehicle key authentication device provided in an embodiment of the present invention. Detailed Implementation

[0068] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0069] When a vehicle's safety element chip malfunctions, the vehicle cannot authenticate the key, unlock the doors, or start the vehicle, forcing the driver to call a tow truck to a repair shop. This significantly impacts the user experience and the vehicle's reputation. To address this problem, this invention provides a vehicle key authentication method. When the microcontroller detects a connection event of the vehicle key, it initiates authentication with the safety element chip. It then obtains the authentication result generated by the safety element chip and determines whether the chip is malfunctioning. If the chip is malfunctioning, it checks the validity of the vehicle key. If valid, it authenticates the key. This allows the microcontroller to authenticate the key even when the safety element chip malfunctions, preventing the inability to authenticate the key and unlock the doors or start the vehicle, thus improving the user experience.

[0070] Reference Figure 1 The diagram illustrates a flowchart of a vehicle key authentication method according to an embodiment of the present invention. The method is applied to a microcontroller, which is installed in a vehicle. The vehicle also has a security element chip installed. The method may specifically include the following steps:

[0071] Step 101: When a connection event of the vehicle key is detected, an authentication for the vehicle key is initiated to the security element chip.

[0072] In this embodiment of the invention, the vehicle may be equipped with a microcontroller unit (MCU) and a safety element chip, such as... Figure 2 The diagram shows a structural block diagram of a vehicle component connection according to an embodiment of the present invention. The microcontroller can be set in the main controller of the vehicle. The main controller can also be equipped with a Bluetooth communication chip and a safety element chip. The microcontroller is communicatively connected to the Bluetooth communication chip and the safety element chip respectively. The vehicle can also be equipped with a central control host and a near-field communication chip. The central control host and the near-field communication chip are respectively connected to the main controller.

[0073] In this embodiment of the invention, when the microcontroller detects a connection event for the vehicle key, it can initiate authentication for the vehicle key with the security element chip. The connection event for the vehicle key can be triggered by either a Bluetooth communication chip or a near-field communication chip.

[0074] Specifically, in this invention, the vehicle key that matches the vehicle can be of two types: one is a card key with NFC (Near Field Communication) functionality, and the other is an application provided by the vehicle manufacturer. The application connects to the vehicle via Bluetooth on the mobile terminal. For example, when unlocking the car door with an NFC-enabled card key, the card key can be brought close to the vehicle's near-field communication chip. The near-field communication chip then triggers a connection event for the vehicle key, allowing subsequent door unlocking. Alternatively, the vehicle can be unlocked via an application provided by the vehicle manufacturer. After logging into the application, the user connects to the vehicle's Bluetooth communication chip via Bluetooth on the mobile terminal. The Bluetooth communication chip then triggers a connection event for the vehicle key, allowing subsequent door unlocking.

[0075] Step 102: Obtain the authentication result generated by the security element chip, and determine whether the security element chip is abnormal based on the authentication result.

[0076] In this embodiment of the invention, after the microcontroller initiates authentication for the vehicle key with the secure element chip, the secure element chip can authenticate the vehicle key. The authentication method in this invention can be as follows: when the microcontroller detects a connection event of the vehicle key, it can obtain the security key corresponding to the vehicle key through a Bluetooth communication chip or a near-field communication chip, and send the security key to the secure element chip. The secure element chip can authenticate the security key and generate a corresponding authentication result. After the secure element chip generates the corresponding authentication result, the microcontroller can obtain the authentication result generated by the secure element chip and determine whether the secure element chip is abnormal based on the authentication result.

[0077] In one embodiment, the authentication result may include failure. Determining whether the security element chip is abnormal based on the authentication result may include: if the authentication result is failure, sending a reset command to the security element chip to cause the security element chip to respond to the reset command and reset; detecting whether the reset of the security element chip is successful; if the reset of the security element chip is unsuccessful, determining that the security element chip is abnormal.

[0078] Specifically, if the certification result of the security element chip is unsuccessful, the microcontroller can send a reset command to the security element chip. After receiving the reset command, the security element chip will reset. If the reset fails, it can be determined that the security element chip is abnormal, indicating that the security element chip has malfunctioned.

[0079] In this embodiment of the invention, if the security element chip is successfully reset, an authentication of the vehicle key is initiated to the security element chip; the authentication result of the security element chip re-authenticating the vehicle key is obtained; and the security element chip is determined to be abnormal based on the authentication result of the re-authentication of the vehicle key.

[0080] Specifically, if the microcontroller determines that the security element chip has been successfully reset, it can initiate authentication of the vehicle key again. The security element chip will authenticate the vehicle key again and generate an authentication result again. The microcontroller can obtain the authentication result generated by the security element again and determine whether the security element chip is abnormal based on the authentication result of the re-authentication of the vehicle key.

[0081] In one embodiment, determining whether the security element chip is abnormal based on the authentication result of re-authenticating the vehicle key may include: determining whether the authentication result is failed or the response timed out; if the authentication result is failed or the response timed out, then determining that the security element chip is abnormal.

[0082] In this invention, if the microcontroller determines that the safety element chip is abnormal, it can send a warning signal to the central control unit. The central control unit can output warning information based on the warning signal, thereby prompting the driver that the safety element chip is abnormal and needs to be repaired in a timely manner.

[0083] Step 103: If the security element chip is abnormal, determine whether the vehicle key is valid.

[0084] In this embodiment of the invention, when the microcontroller determines whether the security element chip is abnormal based on the authentication result, if the security element chip is determined to be abnormal, it can then determine whether the vehicle key is valid.

[0085] In one embodiment, the vehicle is further equipped with a near-field communication (NFC) chip. When a connection event of the vehicle key is detected, authentication of the vehicle key is initiated with the security element chip. This may include: when a connection event of the vehicle key triggered by the NFC chip is detected, obtaining first key identity information corresponding to the vehicle key sent by the NFC chip; the first key identity information is obtained by the NFC chip from the vehicle key; sending the first key identity information to the security element chip and initiating authentication of the vehicle key; determining whether the vehicle key is valid, which may include: determining whether the first key identity information is the same as pre-stored second key identity information; if the first key identity information is the same as the second key identity information, then the vehicle key is determined to be valid.

[0086] Specifically, when a driver uses a key card with NFC functionality to unlock the car door, they can bring the key card close to the vehicle's near-field communication (NFC) chip. This triggers a connection event for the vehicle key. At this time, the microcontroller can obtain the first key identity information corresponding to the key card through the NFC chip and determine whether the first key identity information is the same as the pre-stored second key identity information. If the first key identity information and the second key identity information are the same, the vehicle key is determined to be valid. The second key identity information can be pre-configured by the driver and stored in the vehicle's EEPROM (Electrically Erasable Programmable Read-Only Memory) non-volatile space.

[0087] In another embodiment, the vehicle may also be equipped with a Bluetooth communication chip; determining whether the vehicle key is valid may further include: determining whether the connection event of the vehicle key is triggered by the Bluetooth communication chip and the connection is successful; if the connection event of the vehicle key is triggered by the Bluetooth communication chip and the connection is successful, then the vehicle key is determined to be valid.

[0088] Specifically, the driver can log in to the application provided by the vehicle scenario and connect to the vehicle via the Bluetooth function of the mobile terminal. This will trigger the vehicle key connection event by the vehicle's Bluetooth communication chip. Since the application provided by the vehicle manufacturer will set a password when logging in, the driver must log in to the application with the password. If the driver successfully logs in to the application with the password and successfully connects to the Bluetooth communication chip of the vehicle, it also indicates that the driver is the owner of the vehicle. Therefore, it can be determined that the vehicle key that has successfully connected to the Bluetooth communication chip is legitimate.

[0089] Step 104: If the vehicle key is valid, then authenticate the vehicle key.

[0090] In this embodiment of the invention, when the microcontroller determines whether the vehicle key is valid, if the vehicle key is valid, it can be authenticated by the microcontroller. It should be noted that the method by which the microcontroller authenticates the vehicle key in this invention can be the same as the method by which the security element chip authenticates the vehicle key. Therefore, when the security element chip malfunctions, the microcontroller can authenticate the vehicle key; if authentication is successful, the vehicle key can be used normally. If authentication fails, the central control unit outputs a corresponding prompt message.

[0091] It should be noted that the microcontroller in this invention authenticates the vehicle key only within the current ignition cycle. The current ignition cycle can refer to the process from when the driver starts / powers on the vehicle to when the vehicle is turned off / powered off. That is, the microcontroller in this invention authenticates the vehicle key only in emergency situations. After the vehicle is turned off / powered off, if the vehicle needs to be started / powered on again, the microcontroller will not authenticate the vehicle key, and the vehicle will not be able to start / power on. This allows the driver to immediately drive the vehicle to a repair center for maintenance after discovering an abnormality in the safety element chip, avoiding the safety risks caused by users not maintaining the safety element chip for a long time.

[0092] In this embodiment of the invention, authenticating a vehicle key may include: determining the number of times the vehicle key will be authenticated by a microcontroller after a security element chip malfunctions; if the number of authentications is less than a preset number, then the vehicle key will be authenticated.

[0093] For example, if the preset number of attempts is 3, and after the safety element chip malfunctions, the microcontroller will authenticate the vehicle key 2 times, then the microcontroller can authenticate the vehicle. After successful authentication, the driver can use the vehicle key normally. This avoids situations where the driver is unable to reach a repair center in time to repair the safety element chip due to the current ignition cycle, resulting in the vehicle key being unusable next time. The preset number of attempts can be set by the driver according to their needs; the specific number of attempts is not limited in this invention.

[0094] In this embodiment of the invention, when a vehicle key connection event is detected, an authentication request for the vehicle key is initiated to the security element chip. The authentication result generated by the security element chip is obtained, and the chip's malfunction is determined based on the result. If the security element chip is malfunctioning, the validity of the vehicle key is determined. If the vehicle key is valid, authentication is performed. Thus, when the security element chip malfunctions, the microcontroller can authenticate the vehicle key, preventing the inability to authenticate the key and unlock the doors or start the vehicle when the security element chip is faulty. This also improves the user experience.

[0095] For better explanation of the present invention, see reference to Figure 3 The present invention will be explained. Figure 3 A flowchart illustrating the steps of another vehicle key authentication method provided by an embodiment of the present invention is shown.

[0096] The microcontroller receives a connection event from the near-field communication chip or Bluetooth communication chip triggered by the vehicle key, and then initiates authentication of the vehicle key with the security element chip. If the authentication result obtained by the microcontroller is successful, the vehicle key can be used normally. If the authentication result obtained by the microcontroller is unsuccessful, a reset command is sent to the security element chip. After receiving the reset command, the security element chip resets. The microcontroller checks whether the reset of the security element chip is successful. If the reset of the security element chip is unsuccessful, it determines that the security element chip is abnormal and sends a warning signal to the central control host. The central control host outputs warning information based on the warning signal.

[0097] If the microcontroller detects that the security element chip has been successfully reset, it will re-initiate authentication for the vehicle key with the security element chip. The security element chip will then re-authenticate the vehicle key and generate a re-authentication result. If the microcontroller obtains a successful re-authentication result for the vehicle key, the vehicle key can be used normally.

[0098] If the microcontroller fails to authenticate the vehicle key again or the response times out, it sends a warning signal to the central control unit (CCU), which then outputs a warning message. Simultaneously, the microcontroller checks the validity of the vehicle key. If invalid, it sends a warning signal to the CCU, which outputs a warning message. If valid, the microcontroller authenticates the vehicle key. If authentication succeeds, the key can be used normally; if authentication fails, it sends a warning signal to the CCU, which outputs a warning message.

[0099] In this embodiment of the invention, when a vehicle key connection event is detected, an authentication request for the vehicle key is initiated to the security element chip. The authentication result generated by the security element chip is obtained, and the chip's malfunction is determined based on the result. If the security element chip is malfunctioning, the validity of the vehicle key is determined. If the vehicle key is valid, authentication is performed. Thus, when the security element chip malfunctions, the microcontroller can authenticate the vehicle key, preventing the inability to authenticate the key and unlock the doors or start the vehicle when the security element chip is faulty. This also improves the user experience.
