[0034] Under the above operating environment, the embodiment of the present invention provides the following Figure 2 The vehicle component identification method shown, Figure 2 is a flow chart of a vehicle component identification method according to an embodiment of the present invention. Figure 2 As shown, the method includes the following implementation steps:

[0035] Step S201, obtaining component manufacturing information and project information corresponding to a target component in a vehicle;

[0036] Step S202, based on the component manufacturing information, determining a serial number field and a model code field, wherein the serial number field is used to represent a bit-by-bit unique serial number of the target component, and the model code field is used to represent model information of a basic model part in the target component;

[0037] Step S203, encode the project information to obtain a project code field;

[0038] Step S204, performing hash data compression processing on the serial number field, the model code field and the project code field to obtain a check code field;

[0039] Step S205, using the serial number field, the model code field, the project code field and the check code field, a target identifier is generated, wherein the target identifier is used to represent the identity information of the target component.

[0040] The above-mentioned component manufacturing information may be the manufacturing information recorded by the above-mentioned target component during the manufacturing stage. According to the component manufacturing information, the bitwise unique serial number of the target component and the model information of the basic model parts can be determined. Through the above-mentioned bitwise unique serial number, it can be ensured that the target component is configured with unique serial identification information. It should be noted that the above-mentioned bitwise unique serial number is not the same as the device serial number. The above-mentioned basic model parts may be parts of the basic model or standard model used in the design and manufacture of the target component. According to the above-mentioned component manufacturing information, the model information of at least one basic model part in the target component is determined.

[0041] The above-mentioned project information may be information of a task project corresponding to the target component. For example, when the above-mentioned target component is an electronic control unit (ECU) of a vehicle, the above-mentioned project information may be ECU project information, and the ECU project includes design tasks and development tasks of the vehicle electronic control system, and the ECU project is used to monitor and control various functions of the vehicle (such as engine control function, brake function, steering function and air conditioning function, etc.). The project code field can be encoded according to the project information.

[0042] Furthermore, the serial number field, the model code field and the project code field are subjected to hash data compression processing to obtain a check code field, which may be a data summary of the serial number field, the model code field and the project code field. The authenticity and integrity of the identity information related to the target component (i.e., the serial number field, the model code field and the project code field) can be determined through the check code field.

[0043] Combined with the above-mentioned serial number field, model code field, project code field and check code field, the generated target identifier can represent the multi-level identity information corresponding to the target component, thereby ensuring the uniqueness of the target identifier, enhancing the flexibility of the target component identifier generation scheme, further improving the accuracy of target component identity recognition, and ensuring the safety and intelligence level of the vehicle.

[0044] In an embodiment of the present invention, the component manufacturing information and project information corresponding to the target component in the vehicle are obtained; based on the component manufacturing information, the serial number field and the model code field are determined, wherein the serial number field is used to represent the bit-by-bit unique serial number of the target component, and the model code field is used to represent the model information of the basic model parts in the target component; the project information is encoded to obtain the project code field; the serial number field, the model code field and the project code field are subjected to hash data compression processing to obtain the check code field; the target identifier is generated by using the serial number field, the model code field, the project code field and the check code field, wherein the target identifier is used to represent the identity information of the target component. Thus, the embodiment of the present invention can achieve the purpose of generating the check code field in combination with the component manufacturing information and the project information of the target component and then generating the target identifier, thereby achieving the technical effect of generating a unique and difficult-to-counterfeit identifier for the target component, improving the flexibility of identifier generation, and enhancing the safety of the vehicle, thereby solving the technical problem that the identifier obtained by the component identifier generation scheme provided in the related art lacks uniqueness, is easy to be counterfeited and has poor flexibility, resulting in poor vehicle safety.

[0045] The above method of the embodiment of the present invention is further introduced below.

[0046] In an application scenario, according to the above method steps provided by an embodiment of the present invention, a vehicle component is configured as follows: Figure 3 The identifier field shown constitutes the generated target identifier. Specifically, Figure 3 As shown, the target identifier includes 16 bytes, recorded as Byte0 to Byte15, and the 16 bytes include a serial number field, a model code field, a project code field and a check code field.

[0047] Optionally, in the above step S202, determining the serial number field based on the component manufacturing information may further include the following execution steps:

[0048] Step S221, parsing the component manufacturing information to obtain a bitwise unique serial number, wherein the bitwise unique serial number is a decimal serial number;

[0049] Step S222: Encode the bit-wise unique serial number into a first number of binary bytes to obtain a serial number field.

[0050] The bit-by-bit unique decimal serial number is parsed from the component manufacturing information to obtain the bit-by-bit unique serial number. A bit-by-bit unique serial number means that each bit in each serial number is unique, and there are no repeated numbers or letters. The use of a bit-by-bit unique serial number to identify and recognize vehicle components can ensure the uniqueness and traceability of the vehicle component. In addition, the design of a bit-by-bit unique serial number can prevent fraudulent incidents of counterfeiting serial numbers and improve the safety of vehicles.

[0051] Furthermore, the above-mentioned first number is used to determine a field length preset for the sequence number field according to scenario requirements, that is, the sequence number field contains a first number of bytes.

[0052] Still like Figure 3 As shown, in the 16 bytes of the target identifier, the first byte (byte 0) to the fifth byte (byte 4) are used to record the serial number field. Each byte includes an eight-bit binary number. Based on this, for example, when the decimal bitwise unique serial number is 6147, Byte0 takes the value of 00000000, Byte1 takes the value of 00000000, Byte2 takes the value of 00000000, Byte3 takes the value of 00011000, and Byte4 takes the value of 00000011. For another example, when the decimal bitwise unique serial number is 8348602, Byte0 takes the value of 00000000, Byte1 takes the value of 00000000, Byte2 takes the value of 01111111, Byte3 takes the value of 10100011, and Byte4 takes the value of 10111010.

[0053] According to the above execution steps of the embodiment of the present invention, the bit-by-bit unique serial number of the target component is recorded in the target identifier, and the target component is identified by the target identifier, so that the bit-by-bit unique serial number of the target component can be tracked and identified.

[0054] Optionally, in the above step S202, based on the component manufacturing information, determining the model code field may further include the following execution steps:

[0055] Step S223, parsing the component manufacturing information to obtain the part number of the basic model part, wherein the part number is an unsigned hexadecimal serial number;

[0056] Step S224: based on a preset effective digit, encode the part number into a second number of binary bytes to obtain a model code field.

[0057] The Basic Model Part Number (BMPN) is parsed from the component manufacturing information. The second number is the length of the model code field determined according to the application scenario requirements, for example, Figure 3 As shown in the figure, the model code field contains 4 bytes, namely the 6th byte (byte 5) and the 9th byte (byte 8). Based on this, the BMPN of the target component is encoded as an unsigned hexadecimal sequence number, which is stored in the memory, and the least significant bit of the BMPN is stored starting from Byte 8 and stored in order to Byte 5, and is filled with 0 until Byte 5 to Byte 8 are fully filled according to the application scenario requirements.

[0058] For example, when the decimal serial number of BMPN is 12608547, in the encoded model code field, Byte5 has a value of 00000000, and the corresponding hexadecimal serial number is 0×00; Byte6 has a value of 11000000, and the corresponding hexadecimal serial number is 0×C0; Byte7 has a value of 10100100, and the corresponding hexadecimal serial number is 0×A4; Byte8 has a value of 00100011, and the corresponding hexadecimal serial number is 0×23.

[0059] According to the above-mentioned execution steps of the embodiment of the present invention, the part number of the basic model part in the target component is recorded in the target identifier, and the target component is identified by the target identifier, so that the basic model part in the target component can be tracked and identified.

[0060] Optionally, in the above step S203, encoding the project information to obtain the project code field may further include the following execution steps:

[0061] Step S231, obtaining a project character string to be encoded from the project information, wherein the project character string includes a plurality of characters in a hexadecimal character encoding format;

[0062] Step S232, encode the project character string into a third number of binary bytes to obtain a project encoding field.

[0063] The project string is obtained from the project information. The format of each character in the project string can be hexadecimal-encoded ASCII (i.e., standard information interchange code format) uppercase letters or numbers. The third number is the length of the project code field determined according to the application scenario requirements, for example, Figure 3 As shown, the item code field contains 4 bytes, namely the 10th byte (ie Byte9) and the 13th byte (ie Byte12).

[0064] For example, when the project string obtained in the project information is "HF01", in the encoded project code field, Byte9 has a value of 01001000, and the corresponding hexadecimal sequence number is 0×48; Byte10 has a value of 01000110, and the corresponding hexadecimal sequence number is 0×46; Byte11 has a value of 00110000, and the corresponding hexadecimal sequence number is 0×30; Byte12 has a value of 00110001, and the corresponding hexadecimal sequence number is 0×31.

[0065] According to the above-mentioned execution steps of the embodiment of the present invention, the component project information corresponding to the target component is recorded in the target identifier, and the target component is identified by the target identifier, so that the component project information corresponding to the target component can be tracked and identified.

[0066] Optionally, in the above step S204, the serial number field, the model code field and the project code field are subjected to hash data compression processing to obtain a check code field, and the following execution steps may also be included:

[0067] Step S241, using a predefined target hash algorithm to perform random mixed calculations on the serial number field, the model code field, and the project code field to obtain a calculation result;

[0068] Step S242, compressing the calculation result to create a hash value, wherein the hash value is a character string of a preset length, and the character string is used to represent summary information of the serial number field, the model code field, and the project code field;

[0069] Step S243, extracting the partial characters at the target position from the hash value;

[0070] Step S244: encode some characters into a fourth number of binary bytes to obtain a check code field.

[0071] The above-mentioned predefined target hash algorithm can be a hash function SHA256, which is an algorithm for creating a smaller "digital fingerprint" (also called a data summary) based on a certain data. The hash function compresses the input data into a data summary, thereby reducing the amount of data and fixing the data format. The hash function SHA256 is used to randomly shuffle and mix the serial number field, the model code field, and the project code field, and the mixed data is compressed to obtain a data fingerprint (also called a hash value or hash value). The above-mentioned data fingerprint is usually represented by a shorter string of random letters and numbers. In the application scenario, the hash function SHA256 is used to calculate a data message of any length, and a 256-bit hash value will be generated.

[0072] The fourth number is the length of the check code field determined according to the application scenario requirements, for example, Figure 3 As shown, the project encoding field includes 3 bytes, namely the 14th byte (ie, Byte 13) and the 16th byte (ie, Byte 15). In the application scenario, the above 256-bit hash value is encoded into the above 3 bytes.

[0073] For example, in the encoded project code field, Byte14 has a value of 00100000, and the corresponding hexadecimal sequence number is 0×20; Byte15 has a value of 00100000, and the corresponding hexadecimal sequence number is 0×20; Byte16 has a value of 00100000, and the corresponding hexadecimal sequence number is 0×20.

[0074] Still like Figure 3 As shown, Byte13 to Byte15 in the target identifier are truncated checksums. The contents of Byte0 to Byte12 are calculated using the hash function SHA256 to obtain the corresponding data summary, which is a 256-bit string. The last 3 bytes of the string are retained and filled into Byte13 to Byte15 of the target identifier. Based on this, according to the checksum field (that is, Byte13 to Byte15) in the target identifier, it is possible to determine whether the contents of Byte0 to Byte12 have been tampered with, thereby determining the integrity and correctness of the target identifier.

[0075] According to the above-mentioned execution steps of the embodiment of the present invention, a verification code field corresponding to the target component is newly added in the target identifier, and the target component is identified by using the target identifier, so that the integrity and authenticity of the identity information corresponding to the target component (including the serial number field, model code word and project code field) can be achieved, so that when the integrity and authenticity of the above-mentioned identity information do not meet the requirements (for example, it has been maliciously tampered with), the corresponding identifier adjustment instruction can be triggered to run, thereby reducing the security risk in the identity identification process of the target component.

[0076] Optionally, in the above step S205, the target identifier is generated by using the serial number field, the model code field, the project code field and the check code field, and the following execution steps may also be included:

[0077] Step S251, arrange and merge the serial number field, model code field, project code field and check code field in a preset order to obtain a target identifier, wherein the preset order is from first to last: serial number field, model code field, project code field, check code field.

[0078] Still like Figure 3 As shown, in the target identifier, the serial number field, model code field, project code field and check code field are arranged in sequence to obtain the above target identifier. That is to say, in the application scenario, the target component is identified using the above 16-byte target identifier, and the multi-level information such as the above serial number field, model code field, project code field and check code field is comprehensively considered to improve the uniqueness and accuracy of the target identifier, and reduce the component identification security risk caused by the component identifier of the target component being easily counterfeited.

[0079] Optionally, the target component is an electronic control unit; the above vehicle component identification method may further include the following method steps:

[0080] Step S261, generating an identity message corresponding to the electronic control unit based on the target identifier;

[0081] Step S262, sending the identity information to a target controller of the vehicle to support the target controller in performing vehicle fault diagnosis related to the electronic control unit.

[0082] The target component is the ECU of the vehicle. The identity message may be a vehicle communication message used to indicate the identity of the ECU. For example, the identity message may be sent to the vehicle controller of the vehicle via the vehicle's communication bus. Further, the vehicle controller may implement a vehicle fault diagnosis function for the ECU based on the identity message.

[0083] In summary, the embodiment of the present invention provides a generation scheme for an ECU identifier (referred to as ECU_ID) based on multi-layer coding rules.
