Detailed Description

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

Before introducing the control method, device, system and storage medium of the digital car key, an application scenario of the embodiment of the disclosure is first described.

Compared with the traditional physical car key, the state of the digital car key can be flexibly managed and controlled. For example, the cloud management platform of the digital car key can dock various external platforms or devices (such as a car factory application, a mobile phone factory native application, a customer service system, an off-line store, etc.), and control and manage the digital car key by sending a remote instruction to the vehicle, such as controlling operations of key sharing, key loss, key recovery, key deletion, etc. on the digital car key.

Fig. 1 is a flow chart illustrating the transmission of an instruction for a digital car key as shown in the present disclosure. Referring to fig. 1, a vehicle factory cloud service may send a remote instruction to a TBOX (Telematics BOX) of a vehicle, and after the TBOX receives the remote instruction, send the remote instruction to a vehicle body central computing platform through a vehicle body internal communication network. And after receiving the remote command forwarded by the TBOX, the vehicle body central computing platform sends the remote command to the digital vehicle key service processor through the vehicle body internal communication network.

The digital car key service processor responds to the remote instruction and returns an execution result to the car body central computing platform. After receiving the execution result returned by the digital car key service processor, the car body central computing platform returns the execution result to the TBOX, and then the TBOX returns the execution result to the cloud service of the car factory. And after the cloud service of the vehicle factory receives the execution result, confirming that the remote instruction is executed.

In some scenarios, however, the vehicle may be in a scenario where communication is difficult, such as a ground garage, where communication between the vehicle and the cloud service is unstable, resulting in that remote commands may not be smoothly transmitted to the vehicle. In some scenarios, an abnormality may also occur in the communication link between the vehicle and the vehicle factory cloud service, at which time the remote instruction of the vehicle factory cloud service may not be smoothly transmitted to the vehicle.

The user's experience of driving in a vehicle may suffer when remote instructions cannot be transmitted to the vehicle. For example, in some scenarios, a digital car key of a vehicle may be in a suspended state. Meanwhile, the vehicle cannot successfully receive a remote instruction for recovering the digital car key function, so that the digital car key cannot be started. The following cycle is eventually formed: the inability of a vehicle to receive a remote command for recovering the digital car key function in the current environment— the need to drive the vehicle to an area where the remote command can be received — the digital car key is suspended results in the inability to drive the vehicle — the need to receive a remote command for recovering the digital car key function — the inability of the vehicle to receive a remote command for recovering the digital car key function in the current environment.

For this reason, the embodiment of the present disclosure provides a control method of a digital car key, which is executed by a server, and the server may be, for example, a car factory cloud service in fig. 1. The service end can also be any device for sending control instructions of the digital car key based on the provision of the digital car key protocol.

Fig. 2 is a flowchart of a method for controlling a digital car key according to an embodiment of the present disclosure, and referring to fig. 2, the method includes:

in step S21, it is determined that the vehicle is in a state in which the instruction reception is abnormal.

In some embodiments, the server may send the first control instruction to the vehicle, and if no response information of the vehicle to the first control instruction is received within a first time length threshold, determine that the vehicle is in a state of abnormal instruction reception.

In some embodiments, the server may determine that the vehicle is in a state of abnormal command reception when detecting that the vehicle is in an offline state.

For example, the server may perform heartbeat detection on the vehicle. If the service end does not receive the heartbeat response of the vehicle within the set time, the vehicle is determined to be in an off-line state, and the vehicle is determined to be in a state with abnormal instruction reception. In this case, the server side can determine that the vehicle is in a state in which the instruction reception is abnormal without transmitting the first control instruction.

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

For example, the server may find the vehicle owner bound to the vehicle and the terminal of the vehicle owner, and send the first control instruction to the terminal. In this way, the terminal can send the received first control command to the vehicle through the near field communication link, and the vehicle can control the state of the digital vehicle key in the vehicle according to the received first control command. The near field communication link may be a communication link based on bluetooth, NFC, UWB or the like technology.

The scheme can transmit the control instruction by means of the terminal, so that the success rate of the transmission of the control instruction can be improved, and the control stability of the digital car key is further improved.

Fig. 3 is a flowchart of a control method of a digital car key according to an embodiment of the present disclosure, and referring to fig. 3, the method includes:

in step S31, it is determined that the vehicle is in a state in which the instruction reception is abnormal.

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

The first control instruction is used for decrypting the vehicle to obtain an original control instruction, and the original control instruction is used for controlling the state of a digital vehicle key in the vehicle.

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

For example, at vehicle registration, the vehicle may generate a public-private key pair and submit the public key of the public-private key pair to the server. In this way, the server side can encrypt the original control instruction through the public key to obtain the first control instruction. In this case, after the vehicle receives the first control instruction, the first control instruction may be decrypted by a private key corresponding to the public key, thereby obtaining the original control instruction.

In some embodiments, the server may encrypt the original control instruction by a symmetric key agreed with the vehicle.

For example, when the server communicates with the vehicle, a symmetric key may be generated, and the symmetric key may be stored in the server and in the vehicle. In step S32, the server may encrypt the original control instruction by using the symmetric key to obtain a first control instruction. In this case, after the vehicle receives the first control instruction, the vehicle may decrypt the first control instruction by using a symmetric key in the vehicle, thereby obtaining the original control instruction.

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

The scheme can transmit the control instruction by means of the terminal, so that the success rate of the transmission of the control instruction can be improved, and the control stability of the digital car key is further improved. In addition, in consideration of transmission of the control command to the vehicle via the external link, the above scheme encrypts the original control command to be transmitted when the control command is transmitted by means of the terminal, so that the safety of the command transmission process can be improved.

Fig. 4 is a flowchart of a control method of a digital car key according to an embodiment of the present disclosure, and referring to fig. 4, the method includes:

in step S41, it is determined that the vehicle is in a state in which the instruction 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, identification number) to the first control instruction. The first identification information may include an ID allocated by the server side for the first control instruction.

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

The first control instruction is used for controlling the state of a digital car key in the vehicle.

In this way, by allocating the first identification information to the first control instruction, the server side is facilitated to determine the relationship between the relevant response result of the vehicle and the instruction sent by the server side.

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

receiving an execution result sent by a vehicle and second identification information associated with the execution result, wherein the execution result and the second identification information are sent by the vehicle after the vehicle resumes networking;

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

and sending the second control instruction and the second identification information to the vehicle under the condition that the execution result represents that the second control instruction fails to be executed.

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

In the scheme, the identification information is distributed for the control instruction, so that the service side is facilitated to determine the relation between the execution result of the vehicle and the control instruction sent by the service side. For example, the server may determine, according to the identification information, a control instruction associated with an execution result, and maintain, according to the execution result, an execution state of the control instruction inside the server. When the control instruction which is not successfully executed exists, the server side can also send the control instruction which is not successfully executed to the vehicle again.

In a possible embodiment, the method further comprises, on the basis of fig. 4:

receiving an encryption execution result sent by a terminal and third identification information associated with the encryption execution result, wherein the encryption execution result and the third identification information are sent to the terminal by a vehicle, and the encryption execution result is obtained by encrypting an original execution result by the vehicle;

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

decrypting the encryption execution result to obtain the original execution result;

and under the condition that the original execution result represents that the execution of the third control instruction fails, sending the third control instruction and the third identification information to the terminal so that the terminal can send the third control instruction and the third identification information to the vehicle through the near field communication link.

That is, the vehicle may encrypt the original execution result to obtain an encrypted execution result. The vehicle may further 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.

And the server side can determine a third control instruction associated with the execution result according to the third identification information. And under the condition that the third control instruction is not successfully executed, the server side can send the third control instruction and the third identification information to the vehicle.

In the scheme, the identification information is distributed to the control instruction, so that the service side is helped to determine the relation between the relevant response result of the vehicle and the control instruction sent by the service side. For example, the server may determine, according to the identification information, a control instruction associated with an execution result, and maintain, according to the execution result, an execution state of the control instruction inside the server. When the control instruction which is not successfully executed exists, the server side can also send the control instruction which is not successfully executed to the vehicle again.

In addition, in the above scheme, when the vehicle sends the original execution result and the third identification information to the server through the terminal, the original execution result is encrypted, so that the safety of information transmission is improved.

In the above embodiments, the control method of the digital car key is exemplified by encrypting the original execution result by the car. However, in some embodiments, the vehicle may 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, the embodiment of the disclosure also provides a control method of the digital car key, which is executed by the terminal. The terminal may be a terminal in any of the above embodiments, and the terminal may be a mobile phone, a tablet device, a wearable device, or the like.

And the server side can determine a third control instruction associated with the execution result according to the third identification information. In some embodiments, in a case where the third control instruction is not successfully executed, the server may send the third control instruction and the third identification information to the vehicle.

It should be noted that the first control instruction may be one or more, for example, the first control instruction may include a series of control instructions. Accordingly, the first identification information may include an 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 may be another control instruction other than the first control instruction, which is not limited by the disclosure.

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

For example, in one implementation, the vehicle may send a first execution result of the first control instruction to the server. For example, the vehicle may send a first execution result of the first control instruction to the server when detecting that the networking state is normal, such as when recovering from the disconnected network state to the networking state.

In one embodiment, 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; and sending the second execution result to the terminal so that the terminal sends the second execution result to the server, wherein the second execution result is used for the server to decrypt and obtain the first execution result.

By encrypting the first execution result, the safety of the data transmission process can be improved.

The embodiments of the steps of the above method have been described in detail in the examples of the control method of the digital car key performed by the execution body of the step, and for brevity of the description, the disclosure is not repeated herein.

Fig. 7 is a control flow chart of a digital car key according to an embodiment of the disclosure, and referring to fig. 7, the flow includes:

the cloud service assembly of the vehicle factory prepares a remote instruction A to be issued to the vehicle, and the remote instruction A is sent to the TBOX of the vehicle through a vehicle-vehicle factory cloud service network communication link customized by the vehicle factory.

And due to the fact that the vehicle is disconnected due to the abnormality, the cloud service of the vehicle factory determines that the vehicle cannot receive the remote command A. I.e., determining that remote instruction a failed to issue.

And the cloud service of the vehicle factory encrypts and generates a remote instruction B according to an encryption algorithm. For example, the remote instruction a may be assigned an instruction ID, and the instruction ID and the remote instruction a may be encrypted together to obtain the remote instruction B.

The cloud service of the vehicle factory sends a remote instruction B to mobile phone equipment of a user (hereinafter, the user is taken as an owner of the vehicle).

The car owner carries the mobile phone equipment to the parking position, and the mobile phone equipment sends a remote instruction B to the digital car key service processor through a near field communication channel (such as NFC, bluetooth and the like).

After the digital car key service processor receives the remote instruction B, the remote instruction B is decrypted according to a decryption algorithm corresponding to the encryption algorithm, a remote instruction A and an instruction ID are obtained, and the remote instruction A is executed.

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

And after the vehicle is recovered to be networked, the instruction ID and the execution result of the remote instruction A are sent to the vehicle factory cloud service through the TBOX.

As illustrated in connection with fig. 7, in some scenarios, a vehicle owner desires to recover a digital vehicle key that has been lost, but after submitting a recovery application to a vehicle factory cloud service, the vehicle factory cloud service detects that the vehicle is in a disconnected state. In this way, the vehicle factory cloud service may send instructions to be sent to the vehicle owner's handset device.

The vehicle owner can carry the mobile phone equipment to go to a vehicle parking position; the mobile phone equipment sends an instruction for recovering the digital car key to the car 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 the usable state, and the car owner can unlock again and drive the car to leave the network breaking area. And after the vehicle resumes networking, the vehicle sends an instruction execution result to the cloud compensation.

By adopting the scheme, under the condition that the vehicle is disconnected, a user can forward a remote instruction to the digital car key service processor of the vehicle through a near field communication channel between the mobile phone equipment and the vehicle, so that the issuing and executing of the digital car key service instruction are completed.
