Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

Before introducing the digital car key control method, device, system and storage medium of the present disclosure, the application scenarios of the embodiments of the present disclosure will be introduced first.

Compared with traditional physical car keys, the status of digital car keys can be flexibly managed and controlled. For example, the cloud management platform for digital car keys can be connected to various external platforms or devices (such as car factory applications, mobile phone factory native applications, customer service systems, offline stores, etc.), Keys are controlled and managed, such as controlling key sharing, key loss reporting, key recovery, and key deletion for digital car keys.

Fig. 1 is a flow chart of the instruction transmission of a digital car key shown in the present disclosure. Referring to Figure 1, the car factory cloud service can send remote instructions to the TBOX (Telematics Box, remote communication terminal) of the vehicle. After receiving the remote instructions, the TBOX sends the remote instructions to the central computing platform of the vehicle body through the internal communication network of the vehicle body. After receiving the remote command forwarded by TBOX, the central computing platform of the vehicle body sends the remote command to the digital car key service processor through the internal communication network of the vehicle body.

The digital car key service processor responds to the remote command and returns the execution result to the vehicle body central computing platform. After receiving the execution result returned by the digital car key business processor, the central computing platform of the vehicle body returns the execution result to TBOX, and then TBOX returns the execution result to the car factory cloud service. After receiving the execution result, the depot cloud service confirms that the remote command has been executed.

However, in some scenarios, the vehicle may be in a communication-difficult scenario such as a basement. At this time, the communication between the vehicle and the cloud service of the car factory is unstable, resulting in remote instructions that may not be transmitted to the vehicle smoothly. In some scenarios, the communication link between the vehicle and the automaker's cloud service may also be abnormal. At this time, the remote command of the automaker's cloud service may not be smoothly transmitted to the vehicle.

When remote commands cannot be transmitted to the vehicle, the user's car experience may be affected. For example, in some scenarios, the vehicle's digital key may be suspended. At the same time, because the vehicle cannot successfully receive the remote command for restoring the function of the digital car key, the digital car key cannot be activated. Finally, the following cycle is formed: the vehicle cannot receive remote commands to restore the function of the digital car key in the current environment —> the vehicle needs to be driven to an area where remote commands can be received —> the digital car key is suspended and the vehicle cannot be driven — >Restoring the function of the digital car key requires receiving a remote command for restoring the function of the digital car key—>The vehicle cannot receive the remote command for restoring the function of the digital car key in the current environment.

To this end, an embodiment of the present disclosure provides a method for controlling a digital car key, which is executed by a server. The server may be, for example, the car factory cloud service in FIG. 1 . Based on the stipulations of the digital car key protocol, the server can also be any device for sending control commands of the digital car key.

Fig. 2 is a flowchart of a digital car key control method shown in an embodiment of the present disclosure. Referring to Fig. 2, the method includes:

In step S21, it is determined that the vehicle is in a state where command reception is abnormal.

In some implementations, the server may send the first control instruction to the vehicle, and if no response information from the vehicle to the first control instruction is received within the first duration threshold, it is determined that the vehicle is in the instruction Receive exception status.

In some implementations, the server may determine that the vehicle is in an abnormal state of receiving instructions when detecting that the vehicle is offline.

Exemplarily, the server can perform heartbeat detection on the vehicle. If the server does not receive a heartbeat response from the vehicle within the set time period, it is determined that the vehicle is offline, and that the vehicle is in an abnormal state of command reception. In this case, the server can determine that the vehicle is in an abnormal state of receiving the instruction without sending the first control instruction.

In step S22, the first control instruction is sent to the terminal of the owner of the vehicle, so that the terminal sends the first control instruction to the vehicle through the near field communication link between the terminal and the vehicle, and the first control instruction is used to control the vehicle Control the state of the digital car key in the car.

For example, the server may search for the owner bound to the vehicle and the owner's terminal, and send the first control instruction to the terminal. In this way, the terminal can send the received first control instruction to the vehicle through the near field communication link, and the vehicle can control the status of the digital car key in the vehicle according to the received first control instruction. Wherein, the near field communication link may be a communication link based on Bluetooth, NFC, UWB and other technologies.

The above solution can transmit the control command by means of the terminal, so it can improve the success rate of control command transmission, and further improve the control stability of the digital car key.

Fig. 3 is a flowchart of a digital car key control method shown in an embodiment of the present disclosure. Referring to Fig. 3, the method includes:

In step S31, it is determined that the vehicle is in a state where command reception is abnormal.

In step S32, the original control instruction is encrypted to obtain the first control instruction.

Wherein, the first control instruction is used to decrypt the vehicle to obtain the original control instruction, and the original control instruction is used to control the state of the digital car key in the vehicle.

In some embodiments, the server may encrypt the original control instruction by using the public key of the vehicle.

Exemplarily, when the vehicle is registered, the vehicle can generate a public-private key pair, and submit the public key in the public-private key pair to the server. In this way, the server can encrypt the original control instruction by using the public key to obtain the first control instruction. In this case, after the vehicle receives the first control instruction, it can decrypt the first control instruction with the private key corresponding to the public key, so as to obtain the original control instruction.

In some implementations, the server can encrypt the original control instruction with a symmetric key agreed with the vehicle.

Exemplarily, when the server communicates with the vehicle, a symmetric key can be generated, and the symmetric key can be stored in the server and the vehicle. In step S32, the server may encrypt the original control instruction with the symmetric key to obtain the first control instruction. In this case, after the vehicle receives the first control instruction, it can decrypt the first control instruction through the symmetric key in the vehicle, so as to obtain the original control instruction.

In step S33, the first control instruction is sent to the terminal of the vehicle owner, so that the terminal sends the first control instruction to the vehicle through the near field communication link between the terminal and the vehicle.

The above solution can transmit the control command by means of the terminal, so it can improve the success rate of control command transmission, and further improve the control stability of the digital car key. In addition, considering that the control command is transmitted to the vehicle via an external link, the above solution also encrypts the original control command to be transmitted when the control command is transmitted through the terminal, so the security of the command transmission process can be improved.

Fig. 4 is a flowchart of a digital car key control method shown in an embodiment of the present disclosure. Referring to Fig. 4, the method includes:

In step S41, it is determined that the vehicle is in a state where command reception is abnormal.

In step S42, first identification information of the first control instruction is generated.

For example, the server may assign an ID (Identity Document, identity identification number) to the first control instruction. The first identification information may include an ID assigned by the server to the first control instruction.

In step S43, the first control instruction and the first identification information are sent to the terminal, so that the terminal sends the first control instruction and the first identification information to the vehicle through a near field communication link.

Wherein, the first control command is used to control the state of the digital car key in the vehicle.

In this way, by assigning the first identification information to the first control instruction, it is helpful for the server to determine the relationship between the relevant response result of the vehicle and the instruction sent by the server.

For example, in a possible implementation manner, on the basis of Fig. 4, the method further includes:

receiving the execution result sent by the vehicle and the second identification information associated with the execution result, the execution result and the second identification information being sent by the vehicle after the network is restored;

determining a second control instruction associated with the execution result according to the second identification information;

In a case where the execution result indicates that the execution of the second control instruction fails, the second control instruction and the second identification information are sent to the vehicle.

That is to say, the vehicle can directly send the execution result of the instruction and the second identification information of the instruction to the server. The server may determine the second control instruction associated with the execution result according to the second identification information. If the second control instruction is not executed successfully, the server may send the second control instruction and the second identification information to the vehicle. Correspondingly, the terminal may send the second control instruction and the second identification information to the vehicle through the near field communication link.

In the above solution, by assigning identification information to the control instruction, it is helpful for the server to determine the relationship between the execution result of the vehicle and the control instruction sent by the server. For example, the server may determine the control instruction associated with the execution result according to the identification information, and maintain the execution state of the control instruction inside the server according to the execution result. When there is an unsuccessfully executed control instruction, the server can also resend the unsuccessfully executed control instruction to the vehicle.

In a possible implementation manner, on the basis of Fig. 4, the method further includes:

receiving the encryption execution result sent by the terminal and the third identification information associated with the encryption execution result, the encryption execution result and the third identification information are sent by the vehicle to the terminal, and the encryption execution result is sent by the vehicle to the original The execution result is encrypted;

determining a third control instruction associated with the encryption execution result according to the third identification information;

Decrypting the encrypted execution result to obtain the original execution result;

In the case where the original execution result indicates that the execution of the third control instruction fails, send the third control instruction and the third identification information to the terminal, so that the terminal can transmit the third control instruction through the near field communication link The third control instruction and the third identification information are sent to the vehicle.

That is to say, the vehicle can encrypt the original execution result to obtain the encrypted execution result. The vehicle may also send the encryption execution result and the third identification information to the terminal, so that the terminal sends the encryption execution result and the third identification information to the server.

The server may determine the third control instruction associated with the execution result according to the third identification information. If the third control instruction is not executed successfully, the server may send the third control instruction and the third identification information to the vehicle.

In the above solution, by assigning identification information to the control instruction, it is helpful for the server to determine the relationship between the relevant response result of the vehicle and the control instruction sent by the server. For example, the server may determine the control instruction associated with the execution result according to the identification information, and maintain the execution state of the control instruction inside the server according to the execution result. When there is an unsuccessfully executed control instruction, the server can also resend the unsuccessfully executed control instruction to the vehicle.

Moreover, in the above solution, when the vehicle sends the original execution result and the third identification information to the server through the terminal, it also encrypts the original execution result, which helps to improve the security of information transmission.

It should be noted that, in the above embodiments, the control method of the digital car key is exemplarily described by taking the encryption of the original execution result by the vehicle as an example. However, in some implementations, the vehicle may also encrypt the original execution result and the third identification information together, and transmit the encrypted result to the terminal, so that the terminal transmits the encrypted result to the server, which is not limited in this disclosure.

Based on the same inventive concept, an embodiment of the present disclosure also provides a method for controlling a digital car key, which is executed by a terminal. The terminal may be the terminal in any of the foregoing embodiments, and the terminal may be a mobile phone, a tablet device, a wearable device, and the like. Fig. 5 is a flowchart of a digital car key control method shown in an embodiment of the present disclosure. Referring to Fig. 5, the method includes:

Wherein, the first control instruction is sent by the server when it is determined that the vehicle is in an abnormal state of receiving the instruction, and the first control instruction is used to control the state of the digital car key in the vehicle.

In a possible implementation manner, the first control instruction is an encrypted control instruction, the first control instruction is obtained by encrypting the original control instruction by the server, and the first control instruction is used for the vehicle to decrypt the obtained The original control instruction is used to control the state of the digital car key in the vehicle.

receiving the encryption execution result sent by the vehicle and the third identification information associated with the encryption execution result, where the encryption execution result is obtained by encrypting the original execution result by the vehicle;

Wherein, the third identification information is used by the server to determine the third control instruction associated with the encrypted execution result, and the encrypted execution result is used by the server to decrypt to obtain the original execution result, and the original The execution result is used by the server to determine whether the third control instruction is successfully executed, so as to send the third control instruction and the third control instruction to the terminal if the third control instruction is not successfully executed. Identification information.

That is to say, the vehicle can encrypt the original execution result to obtain the encrypted execution result. The vehicle may also send the encryption execution result and the third identification information to the terminal, so that the terminal sends the encryption execution result and the third identification information to the server.

The server may determine the third control instruction associated with the execution result according to the third identification information. In some implementations, if the third control instruction is not executed successfully, the server may send the third control instruction and the third identification information to the vehicle.

It should be noted that there may be one or more first control instructions, for example, the first control instructions may include a series of control instructions. Correspondingly, the first identification information may include the identification of each control instruction in the series of control instructions. In the above embodiment, the third control instruction may be one or more control instructions in the series of control instructions, or other control instructions other than the first control instruction, which is not limited in the present disclosure. .

In the above solution, by assigning identification information to the control instruction, it is helpful for the server to determine the relationship between the relevant response result of the vehicle and the control instruction sent by the server. For example, the server may determine the control instruction associated with the execution result according to the identification information, and maintain the execution state of the control instruction inside the server according to the execution result. When there is an unsuccessfully executed control instruction, the server can also resend the unsuccessfully executed control instruction to the vehicle.

It is also worth noting that, for the above method embodiments, for the sake of simple description, they are expressed as a series of action combinations, but those skilled in the art should know that the present disclosure is not limited by the described action sequence. For example, the step of receiving the first identification information of the first control instruction sent by the server and the step of receiving the first control instruction sent by the server may be performed together or sequentially; The step of providing the first identification information and the step of sending the first control instruction to the vehicle through a near field communication link may also be performed together or sequentially. Secondly, those skilled in the art should also know that the embodiments described in the specification are all examples, and the actions involved are not necessarily required by the present invention.

Based on the same inventive concept, an embodiment of the present disclosure further provides a method for controlling a digital car key, which is executed by a vehicle, and the vehicle may be the vehicle involved in any of the above embodiments. Fig. 6 is a flowchart of a digital car key control method shown in an embodiment of the present disclosure. Referring to Fig. 6, the method includes:

Wherein, the first control instruction is sent to the terminal when the server determines that the vehicle is in an abnormal state of receiving the instruction, and the first control instruction is used to control the state of the digital car key in the vehicle.

For the way in which the server sends the first control command and the way in which the terminal sends the first control command to the vehicle, please refer to the above-mentioned digital car key control method executed by the server and the above-mentioned digital car key executed by the terminal. The embodiment of the key control method is described, and for the sake of brevity of the description, this disclosure will not describe it in detail.

In step S62, the first control instruction is executed.

The above solution can transmit the control command by means of the terminal, so it can improve the success rate of control command transmission, and further improve the control stability of the digital car key.

In a possible implementation manner, the first control instruction is an encrypted control instruction, and the first control instruction is obtained by encrypting the original control instruction by the server, and the original control instruction is used to encrypt the digital data in the vehicle. The state of the car key is controlled, and the execution of the first control instruction includes:

The above solution can transmit the control command by means of the terminal, so it can improve the success rate of control command transmission, and further improve the control stability of the digital car key. In addition, considering that the control command is transmitted to the vehicle via an external link, the above solution also encrypts the original control command to be transmitted when the control command is transmitted through the terminal, so the security of the command transmission process can be improved.

In a possible implementation manner, after the vehicle executes the first control instruction, it may also send the first execution result of the first control instruction to the server.

For example, in one implementation manner, the vehicle may send the first execution result of the first control instruction to the server. For example, the vehicle may send the first execution result of the first control instruction to the server when it detects that the networked state is normal, such as recovering from the disconnected state to the connected state.

In an implementation manner, the vehicle may send the first execution result to the server through the terminal. For example, the vehicle may encrypt the first execution result of the first control instruction to obtain a second execution result; send the second execution result to the terminal, so that the terminal sends the second execution result To the server, the second execution result is used by the server to decrypt to obtain the first execution result.

Fig. 7 is a control flowchart of a digital car key shown in an embodiment of the present disclosure. Referring to Fig. 7, the process includes:

The car factory cloud service assembles the remote command A that is ready to be delivered to the vehicle, and sends the remote command A to the vehicle's TBOX through the vehicle-car factory cloud service network communication link customized by the car factory.

The vehicle is disconnected from the network due to abnormal reasons, and the car factory cloud service determines that the vehicle cannot receive remote command A. That is, it is determined that the delivery of the remote command A fails.

The car factory cloud service encrypts and generates remote command B according to the encryption algorithm. For example, remote command A may be assigned a command ID, and the command ID and remote command A may be encrypted together to obtain remote command B.

The car factory cloud service sends the remote command B to the mobile phone device of the user (the user is used as the example of the car owner in the following).

The car owner brings the mobile phone device to the parking position of the vehicle, and the mobile phone device sends the remote command B to the digital car key service processor through the near-field communication channel (such as NFC, Bluetooth, etc.).

After receiving the remote command B, the digital car key service processor decrypts the remote command B according to the decryption algorithm corresponding to the encryption algorithm, obtains the remote command A and command ID, and executes the remote command A.

The digital car key service processor sends the execution result of remote command A and the command ID to VCCD (Vehicle Central Controller Domain, the vehicle central control unit), and VCCD sends the execution result of remote command A and the command ID to TBOX.

After the vehicle is back online, the command ID and the execution result of remote command A are sent to the car factory cloud service through TBOX.

An example is given in conjunction with Figure 7. In some scenarios, the car owner expects to restore the digital car key that has been reported lost, but after submitting a recovery application to the car factory cloud service, the car factory cloud service detects that the vehicle is disconnected from the network. In this way, the car factory cloud service can send the instructions to be sent to the vehicle to the car owner's mobile phone device.

The owner of the car can take the mobile phone device to the parking position of the vehicle; the mobile phone device sends an instruction to restore the digital car key to the vehicle digital car key service processor through the near-field communication channel; after the digital car key service processor executes the instruction, the digital car key is restored to In the available state, the owner can re-unlock and drive the vehicle out of the disconnected area. After the vehicle is back online, the vehicle sends the command execution result to the cloud compensation.

With the above solution, when the vehicle is disconnected from the network, the user can also forward the remote command to the vehicle's digital car key service processor through the near-field communication channel between the mobile phone device and the vehicle, and then complete the downloading of the digital car key service command. issue and execute.
