[0075] To make the above objects, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0076] Figure 1 The vehicle control method provided by the embodiment of the present invention is shown, which is applied to a PEPS controller of a vehicle. The method includes the following steps:

[0077] Step S101: Receive an encrypted control instruction forwarded by the communication module of the vehicle. The encrypted control instruction comes from a key terminal, and the encrypted control instruction carries a first identifier, where the first identifier represents the data type of the encrypted control instruction. Among them, the key terminal is an ordinary key terminal or a digital key terminal. The data type of the encrypted control instruction sent by the ordinary key terminal is a high-frequency data type, and the data type of the encrypted control instruction sent by the digital key terminal is a short-range wireless communication data type.

[0078] In the above step S101, the encrypted control instruction is sent by an ordinary key terminal or a digital key terminal. The ordinary key terminal refers to a traditional integrated remote control key, and the data type of the encrypted control instruction it sends is a high-frequency data type; since the digital key has no substantial form and can realize the key function through a mobile phone or a smart wearable device, the digital key terminal refers to a mobile phone or a smart wearable device that can realize the key function. There are many types of digital keys, including: Bluetooth keys, NFC keys, and UWB keys, etc. The data type of the encrypted control instruction sent by the digital key terminal is a short-range wireless communication data type, that is, the encrypted control instructions sent by different types of digital keys such as Bluetooth keys, NFC keys, and UWB keys all belong to the short-range wireless communication data type.

[0079] The PEPS (Passive Entry Passive Start) controller of the vehicle is connected to the communication module of the vehicle through the Controller Area Network (CAN) bus. That is, the PEPS receives the encrypted control instructions forwarded from the communication module through the CAN bus. The encrypted control instructions received by the PEPS carry a first identifier that can characterize the data type of the encrypted control instructions. The PEPS controller can determine the data type of the encrypted control instructions according to the first identifier. The first identifier is divided into a high-frequency data identifier and a near-field wireless communication data identifier. In addition, the communication module for forwarding the encrypted control instructions sent by the key terminal refers to the near-field wireless communication module. This communication module has multiple data transmission functions and can simultaneously receive the encrypted control instructions of the high-frequency data type sent by the ordinary key terminal and the encrypted control instructions of the near-field wireless communication data type sent by the digital key terminal, and send the received encrypted control instructions to the PEPS controller through the CAN bus.

[0080] Step S102: According to the first identifier, decrypt the encrypted control instructions according to the instruction decryption algorithm corresponding to the first identifier, and execute the decrypted control instructions.

[0081] In the above step S102, the instruction decryption algorithm refers to the decryption algorithm used to decrypt the encrypted control instructions. The instruction decryption algorithms for encrypted control instructions of different data types are different. According to the first identifier, the data type of the encrypted control instructions can be identified. Therefore, according to the type of the first identifier, the instruction decryption algorithm for decrypting the encrypted control instructions can be determined. When the PEPS controller receives the encrypted control instructions, it first identifies the first identifier carried in the encrypted control instructions, and judges the instruction decryption algorithm for decrypting the encrypted control instructions according to the first identifier. Then, it decrypts the received encrypted control instructions according to the decryption algorithm corresponding to the first identifier, and controls the vehicle to execute the corresponding control functions. The corresponding control functions include: key functions such as turning off the engine, unlocking, and opening the door.

[0082] In this embodiment, the same PEPS is used to control and receive the encrypted control instructions forwarded from different key terminals by the communication module, decrypt the encrypted control instructions according to the instruction decryption algorithm corresponding to the first identifier carried in the encrypted control instructions, and control the vehicle to execute the decrypted control instructions to realize the key functions. Compared with the previous relatively independent design of digital keys and ordinary keys, this method realizes the control of the vehicle by two different keys based on the same set of hardware systems, reduces the number of key device parts, reduces the development difficulty and process inconsistency problems, saves the design cost, and realizes the integrated design of different key systems.

[0083] In an alternative embodiment, according to the first identifier, decrypt the encrypted control instruction according to the instruction decryption algorithm corresponding to the first identifier, and execute the decrypted control instruction, including:

[0084] Determine the data type of the encrypted control instruction according to the first identifier, and extract a function indication bit from the encrypted control instruction, where the function indication bit represents the control function indicated by the encrypted control instruction;

[0085] According to the first identifier and the function indication bit, determine a second identifier for decrypting the instruction decryption algorithm corresponding to the encrypted control instruction, where the second identifier represents the type of the instruction decryption algorithm;

[0086] Decrypt the encrypted control instruction according to the decryption algorithm indicated by the second identifier, and execute the decrypted control instruction.

[0087] In this embodiment, the instruction decryption algorithms for encrypted control instructions of different data types and different functions are different, that is, the instruction decryption algorithms for encrypted control instructions with the same control function but different data types are different, and the instruction decryption algorithms for encrypted control instructions with the same data type but different control functions are different. For example, the instruction decryption algorithms for the "open the car door" encrypted control instruction of the high-frequency data type and the "open the car door" encrypted control instruction of the near-field wireless communication data type are different, and the instruction decryption algorithms for the "open the car door" encrypted control instruction of the high-frequency data type and the "lock the car door" encrypted control instruction of the high-frequency data type are also different. Since the data type of the encrypted control instruction can be judged according to the first identifier in the encrypted control instruction, and the control function of the encrypted control instruction can be determined according to the function indication bit, therefore, after receiving the encrypted control instruction, the PEPS controller judges the instruction decryption algorithm for decrypting the encrypted control instruction according to the first identifier and the function indication bit.

[0088] In a preferred embodiment, the vehicle is configured with multiple communication modules, and the method further includes:

[0089] The encrypted control instruction carries the first identifier and an identity tag, where the identity tag represents the identity information of the communication module;

[0090] Decrypt the encrypted control instruction according to the decryption algorithm indicated by the second identifier, and execute the decrypted control instruction, including: decrypt each encrypted control instruction according to the decryption algorithm to obtain a decrypted control instruction, where the control instruction carries an identity tag; compare multiple control instructions; when at least two of the control instructions are the same, execute the control instruction.

[0091] In this embodiment, a plurality of communication modules are configured in the vehicle. Each communication module has multiple data transmission functions, can receive the encrypted control instructions sent by the digital key terminal and the ordinary key terminal, and send the encrypted control instructions to the PEPS controller. Each communication module has a unique identity tag that can represent its own identity information. The identity tag of the communication module is carried in the encrypted control instructions forwarded by each communication module. The PEPS controller can query the corresponding communication module according to the identity tag. After the PEPS controller decrypts multiple received encrypted control instructions, the control instructions obtained after decryption still carry the identity tag. The PEPS controller compares the control instructions carrying different identity tags. If the data in at least two control instructions is exactly the same, it indicates that the data of the control instructions has not been modified and the control instructions are accurate. Furthermore, the PEPS controller controls the vehicle to execute the control instructions.

[0092] In this embodiment, since each communication module can receive the encrypted control instructions sent by different key terminals, it avoids the key function failure caused by a communication module not receiving the encrypted control instructions sent by the key terminal. Moreover, the PEPS controller compares multiple control instructions to avoid the key function failure caused by a certain data being modified, thereby ensuring the accuracy of the key function control.

[0093] In an alternative embodiment, before receiving the encrypted control instructions forwarded by the communication module of the vehicle, it further includes:

[0094] Receiving the control instructions sent by the key terminal, obtaining the pre-set root secret key paired with the key terminal from the cloud server, and specifying a third identifier for the key encryption algorithm used to encrypt the pre-set root secret key. The third identifier represents the type of the key encryption algorithm;

[0095] Encrypting the pre-set root secret key according to the key encryption algorithm, and sending the encrypted pre-set root secret key to the key terminal to implement the legitimacy verification of the key terminal by using the encrypted pre-set root secret key.

[0096] In this embodiment, before the PEPS controller receives the encrypted control instruction forwarded by the communication module, it is also necessary to verify the legitimacy of the key terminal. The PEPS controller first receives the control instruction sent by the key terminal. This control instruction refers to an unencrypted control instruction that is directly sent from the key terminal to the PEPS controller. After the PEPS controller receives the control instruction sent by the key terminal, it obtains the preset root key paired with the key terminal from the cloud server. Each type of key terminal corresponds to a different preset root key. The preset root key of the ordinary key terminal is of the low-frequency data type, and the preset root key of the digital key terminal is of the near-field wireless communication data type. The preset root key contains information for identity verification such as vehicle information, key information, and verification password. In addition, the PEPS controller designates a key encryption algorithm for encrypting the preset root key. The type of this key encryption algorithm is related to the type of the key terminal, that is, the key encryption algorithms for the preset root keys of the ordinary key terminal and the digital key are different. After the PEPS controller encrypts the preset root key according to the key encryption algorithm, it sends the encrypted preset root key to the key terminal.

[0097] After receiving the encrypted preset root key, the key terminal decrypts the encrypted preset root key to obtain the preset root key, and compares the information contained in the preset root key with the information pre-stored in the key terminal. If the information is consistent, the verification passes. For example, if the license plate number information contained in the preset root key is consistent with the license plate number information pre-stored in the key terminal, the verification passes, indicating that the key terminal can control the vehicle. After the verification passes, the key terminal sends out the encrypted control instruction, and the communication module forwards the encrypted control instruction to the PEPS controller.

[0098] In this embodiment, before the key terminal controls the vehicle, it is necessary to verify the legitimacy of the key terminal, which ensures the safety of vehicle control; during the verification process, when the PEPS controller sends the preset root key, it needs to encrypt the preset root key, which further improves the security.

[0099] In an alternative embodiment, encrypting the preset root key according to the key encryption algorithm and sending the encrypted preset root key to the key terminal includes:

[0100] Sending the preset root key and the third identifier to the security chip in the PEPS controller of the vehicle;

[0101] Encrypting the preset root key according to the key encryption algorithm represented by the third identifier, and sending the encrypted preset root key to the key terminal.

[0102] The PEPS controller in the vehicle contains an MCU (Microcontroller Unit) and a security chip. The security chip is responsible for verifying the identity of critical data (for example, verifying the identity of a digital key terminal or a regular key terminal). In practical applications, the MCU sends the preset root key obtained from the cloud server and the third identifier of the key encryption algorithm for encrypting the preset root key to the security chip. Here, the third identifier represents the type of the key encryption algorithm, and the security chip can determine the key encryption algorithm for encrypting the preset root key based on the third identifier. After receiving the preset root key and the third identifier, the security chip encrypts the preset root key according to the key encryption algorithm corresponding to the third identifier and returns the encrypted preset root key to the MCU. Finally, the MCU sends the received encrypted preset root key to the key terminal.

[0103] In this embodiment, encrypting the preset root key by the security chip improves the security. The preset root keys of different key terminals are encrypted based on the security chip of the same PEPS controller, reducing the number of security chips used. And by sharing one security chip, the development difficulty and the problem of process inconsistency are reduced, and the cost is saved at the same time.

[0104] In an optional embodiment, the sending the encrypted preset root key to the key terminal includes:

[0105] When the key terminal is a regular key terminal, the encrypted preset root key is sent to the regular key terminal through a low-frequency antenna;

[0106] When the key terminal is a digital key terminal, the encrypted preset root key is sent to the digital key terminal through a short-range wireless communication channel between the digital key terminal and the PEPS controller.

[0107] In practical applications, the data type of the preset root key corresponding to the regular key terminal is a low-frequency data type, and low-frequency data can only be transmitted through a low-frequency antenna for data line transmission. The data type of the preset root key corresponding to the digital key terminal is a short-range wireless communication data type, and short-range wireless communication data can be transmitted through a short-range wireless communication channel. Therefore, when the key terminal is a regular key terminal, the PEPS controller sends the encrypted preset root key to the regular key terminal through a low-frequency antenna. When the key terminal is a digital key terminal, the PEPS controller directly sends the encrypted preset root key to the digital key terminal through a short-range wireless communication channel.

[0108] As Figure 2 shown, according to another aspect of the present invention, a vehicle control method is provided, which is applied to the communication module of the vehicle. The method includes:

[0109] Step S201: Receive an encrypted control instruction sent by a key terminal of the vehicle, where the key terminal is an ordinary key terminal or a digital key terminal.

[0110] Step S202: Add a first identifier to the encrypted control instruction according to the data type of the encrypted control instruction, where the data type of the encrypted control instruction sent by an ordinary key terminal is a high-frequency data type, and the data type of the encrypted control instruction sent by a digital key terminal is a near-field wireless communication data type.

[0111] Step S203: Forward the encrypted control instruction carrying the first identifier to the PEPS controller of the vehicle to trigger the PEPS controller to decrypt the encrypted control instruction carrying the first identifier and execute the decrypted control instruction.

[0112] In this embodiment, the communication module is a near-field wireless communication module, which has multiple data transmission functions, can receive an encrypted control instruction of a high-frequency data type sent by an ordinary key terminal and an encrypted control instruction of a near-field wireless communication data type sent by a digital key terminal, and send the received encrypted control instruction to the PEPS controller through the CAN bus.

[0113] After receiving the encrypted control instruction, the communication module can identify the data type of the encrypted control instruction. The data types of the encrypted control instruction include a high-frequency data type and a near-field wireless communication data type. After the communication module determines the data type of the encrypted control instruction, a first identifier is added to the encrypted control instruction. The first identifier represents the data type of the encrypted control instruction, including a high-frequency data identifier and a near-field wireless communication data identifier. Specifically, a high-frequency data identifier is added to the encrypted control instruction of the high-frequency data type sent by the ordinary key terminal, and a near-field wireless communication data identifier is added to the encrypted instruction of the near-field wireless communication data type sent by the digital key terminal.

[0114] In this embodiment, the same communication module is used to receive the encrypted control instructions of the ordinary key terminal or the digital key terminal and forward the encrypted control instructions to the PEPS controller, realizing the integrated design of two different types of key systems and solving the problem of a large number of key parts caused by the independent design of different key hardware systems in the past.

[0115] In an optional embodiment, before adding a first identifier to the encrypted control instruction according to the data type of the encrypted control instruction, the method further includes:

[0116] Determine the data type and the indicated control function of the encrypted control instruction;

[0117] Determine the standard length corresponding to the encryption control instruction according to the data type and the control function, where encryption control instructions with different data types and different control functions correspond to different standard lengths;

[0118] Verify whether the length of the encryption control instruction is consistent with the standard length;

[0119] Add a first identifier to the encryption control instruction according to the data type of the encryption control instruction, including: when the length is consistent with the standard length, add a first identifier to the encryption control instruction according to the data type of the encryption control instruction.

[0120] Since the lengths of encryption control instructions with different data types and different control functions are different, that is, the lengths of encryption control instructions with the same control function but different data types are different, and the lengths of encryption control instructions with the same data type but different control functions are different. For example, the "open the car door" encryption control instruction of the high-frequency data type and the "open the car door" encryption control instruction of the near-field wireless communication data type have different lengths, and the "open the car door" encryption control instruction of the high-frequency data type and the "lock the car door" encryption control instruction of the high-frequency data type also have different lengths. Therefore, each encryption control instruction with different control functions and different data types has a standard length, and the standard lengths of various encryption control instructions are pre-stored in the communication module. When the communication module receives an encryption control instruction sent from the key terminal, it identifies the data type of the encryption control instruction and determines the control function corresponding to the encryption control instruction, queries the pre-stored standard length of the encryption control instruction according to the data type and the control function, and compares the length of the received encryption control instruction with the standard length. If the lengths of the two are consistent, it indicates that the encryption control instruction is accurate, and after adding a first identifier representing the data type to the encryption control instruction, it is forwarded to the PEPS controller.

[0121] In this embodiment, by verifying the length of the encryption control instruction, the accuracy of the encryption control instruction is ensured, and the vehicle control safety is further improved.

[0122] As Figure 3 shown, according to another aspect of the present invention, a vehicle control method is provided, which is applied to the key terminal of the vehicle. The method includes:

[0123] Step S301: Determine the instruction encryption algorithm according to the data type of the control instruction to be sent by the key terminal.

[0124] Step S302: Encrypt the control instruction according to the instruction encryption algorithm to obtain an encryption control instruction.

[0125] Step S303: Send the encrypted control instruction to the communication module of the vehicle to trigger the communication module to add a corresponding first identifier to the encrypted control instruction, and then forward the encrypted control instruction carrying the first identifier to the PEPS controller of the vehicle.

[0126] In this embodiment, the key terminal sends out the encrypted control instruction which is the control instruction after being encrypted. The encryption process does not change the data type of the control instruction, that is, the data types of the control instruction and the encrypted control instruction are the same. The data types of the control instructions sent by different key terminals are different, and the corresponding instruction encryption algorithms for different data type control instructions are different. That is, the high-frequency data type corresponds to the instruction encryption algorithm for high-frequency data, and the near-field wireless communication data type corresponds to the instruction encryption algorithm for near-field wireless communication data. Before the key terminal sends the encrypted control instruction, the control instruction is first encrypted according to the instruction encryption algorithm corresponding to its data type, and then the encrypted control instruction is sent to the communication module. In addition, the control instruction is encrypted by using a symmetric encryption method, that is, the encryption method and the decryption method of the control instruction are the same, and the instruction encryption algorithm and the instruction decryption algorithm of the control instruction can be determined through the data type of the control instruction.

[0127] In this embodiment, the control instruction is encrypted to prevent the control instruction from being maliciously modified during the transmission process, ensure the accuracy of the control instruction, and improve the security of the key system.

[0128] In an alternative embodiment, the method further includes: determining the control function indicated by the control instruction to be sent by the key terminal; determining the instruction encryption algorithm according to the data type of the control instruction to be sent by the key terminal, including: determining the instruction encryption algorithm according to the data type of the control instruction to be sent by the key terminal and the control function.

[0129] In this embodiment, the instruction encryption algorithms for encrypting control instructions with different control functions and different data types are different. For example, the instruction encryption algorithms for encrypting the high-frequency data type control instruction of "opening the door" and the near-field wireless communication data type control instruction of "opening the door" are different, and the instruction encryption algorithms for encrypting the high-frequency data type control instruction of "opening the door" and the high-frequency data type control instruction of "ignition" are different. Therefore, before encrypting the control instruction, the key terminal determines the instruction encryption algorithm according to the control function and data type corresponding to the control instruction.

[0130] In an alternative embodiment, the method further includes: sending a control instruction to the PEPS controller; receiving an encrypted preset root secret key sent by the PEPS controller of the vehicle; using the encrypted preset root secret key to verify the legitimacy of the key terminal; and sending the encrypted control instruction to the communication module of the vehicle, including: after the legitimacy verification of the key terminal passes, sending the encrypted control instruction to the communication module of the vehicle.

[0131] In this embodiment, when the user controls the vehicle through the key terminal, the key terminal first sends a control instruction to the PEPS controller of the vehicle. This function instruction is an unencrypted control instruction. After receiving the control instruction, the PEPS controller returns an encrypted preset root secret key to the key terminal. After receiving the encrypted preset root secret key, the key terminal decrypts the encrypted preset root secret key. If the information contained in the preset root secret key queried after decryption is consistent with the information pre-stored in the key terminal, it indicates that the key terminal is legitimate and can control the vehicle. After the legitimacy verification passes, the key terminal encrypts the control instruction and then sends the encrypted control instruction to the communication module.

[0132] In practical applications, the user only needs to perform one operation on the key terminal. The key terminal first sends a control instruction to the PEPS controller to verify the legitimacy of the key terminal. After the legitimacy verification of the key terminal passes, the key terminal automatically sends an encrypted control instruction, so that the communication module forwards the encrypted control instruction to the PEPS controller to execute the corresponding control function.

[0133] Figure 4 The schematic diagram of the application scenario of the embodiment of the present invention is shown. The digital key terminal 11 and the ordinary key terminal 12 respectively establish signal connections with the PEPS controller installed on the vehicle 15, so that the digital key terminal 11 sends a control instruction of the short-range wireless communication data type to the PEPS controller, and the PEPS controller sends the encrypted preset root secret key to the digital key terminal 11; and the ordinary key terminal 12 sends a control instruction of the high-frequency data type to the PEPS controller, and the PEPS controller sends the encrypted preset root secret key to the ordinary key terminal 12 through the low-frequency antenna 14; the communication module 13 respectively establishes signal connections with the digital key terminal 11 and the ordinary key terminal 12, and is connected to the PEPS controller of the vehicle through the CAN connection, so as to realize that the communication module 13 receives the encrypted control instruction sent by the key terminal and sends the encrypted control instruction to the PEPS controller.

As Figure 5As shown, the key terminals include a digital key terminal and a regular key terminal. Multiple communication modules are configured in the vehicle. The communication modules can receive signals of both the short-range wireless communication data type and the high-frequency data type, that is, receive the encrypted control instructions sent by different key terminals. The PEPS controller includes a micro control unit (MCU) and a security chip. The MCU is used to acquire and send data and control the vehicle. The security chip is used to verify the identity of key data. For example, verify the identity of the digital key or the regular key. The communication module is connected to the PEPS controller through CAN. A low-frequency antenna is also configured in the vehicle. The low-frequency antenna is connected to the PEPS controller.
