DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0019] In a first aspect, an embodiment of the present application provides a method for implementing a USB flash drive upgrade of an automobile instrument system.

[0020] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the method for implementing the USB flash drive upgrade of the automobile instrument system in this application. Figure 1 As shown, the method for implementing the USB flash drive upgrade of the automobile instrument system includes: S1: Create corresponding public and private keys, and encrypt the target file containing the instrument configuration information request instruction based on the public key and write it to the USB flash drive; S2: decrypting the target file of the USB flash drive inserted into the vehicle instrument based on the private key, obtaining the instrument configuration information request instruction and executing it to obtain the instrument configuration information; S3: Obtaining an upgrade package for the current version of the vehicle instrument to be upgraded based on the obtained instrument configuration information, generating an upgrade instruction for indicating the current version of the vehicle instrument to be upgraded based on the public key, and writing the upgrade package and upgrade execution instruction into a USB flash drive; S4: Decrypting the upgrade instruction based on the private key to obtain the current version of the automobile instrument that needs to be upgraded and comparing it with the current automobile instrument information, and upgrading the automobile instrument based on the upgrade package according to the comparison result.

[0021] Furthermore, in one embodiment, a corresponding public key and private key are created, and a target file containing a meter configuration information request instruction is encrypted based on the public key and then written to a USB flash drive, specifically including: S101: Create a corresponding pair of public and private keys, and store the private key in a car meter; S102: Create an instrument configuration information request instruction, and write the created instrument configuration information request instruction into the created target file; S103: Encrypt the target file based on the public key, and write the encrypted target file into the USB flash drive.

[0022] Specifically, a public key and a private key are created, where the private key runs in the car instrument and the public key is used by the client. Then, an instrument configuration information request instruction is created to obtain the instrument configuration information, and the created instrument configuration information request instruction is written into the created target file. The target file is encrypted using the public key, and the encrypted target file is copied to a USB flash drive.

[0023] Furthermore, in one embodiment, decrypting a target file on a USB flash drive inserted into a car instrument panel based on the private key, obtaining the instrument configuration information request instruction and executing the instruction to obtain the instrument configuration information specifically includes: S201: inserting the USB disk containing the target file into the USB port of the vehicle instrument panel; S202: After the vehicle instrument detects and obtains the USB flash drive, the target file is decrypted using the private key to obtain an instrument configuration information request instruction; S203: Execute the instrument configuration information request instruction to obtain the instrument configuration information and write it into the USB disk, and disconnect the USB disk from the USB interface of the vehicle instrument.

[0024] Specifically, a USB flash drive containing a target file is inserted into the USB port of a car instrument. After the car instrument detects the USB flash drive, it uses a private key to decrypt the target file in the USB flash drive, obtains an instrument configuration information request instruction, and executes corresponding operations according to the instrument configuration information request instruction to obtain the instrument configuration information. The obtained instrument configuration information is then written to the USB flash drive, and the USB flash drive is unplugged.

[0025] In this application, instrument configuration information includes the instrument MCU (Micro Controller Unit) version, the instrument SoC (System on Chip) version, instrument configuration parameter information, and the vehicle VIN (Vehicle Identification Number). Instrument configuration parameter information includes basic instrument configuration parameters.

[0026] Furthermore, in one embodiment, an upgrade package for the version of the automobile instrument currently to be upgraded is obtained based on the obtained instrument configuration information, and an upgrade instruction for indicating the version of the automobile instrument currently to be upgraded is generated based on the public key, and the upgrade package and the upgrade execution instruction are written to a USB flash drive, specifically including: S301: Reading instrument configuration information from a USB flash drive based on the client, and establishing a connection between the client and a remote server to send the read instrument configuration information to the remote server; S302: Based on the instrument configuration information, the remote server returns all currently upgradeable version information of the automobile instrument to the client; S303: The client selects the version to be upgraded based on the information of all currently upgradeable versions of the vehicle instrument returned by the remote server, and downloads the upgrade package corresponding to the currently upgraded version to a USB flash drive; S304: Generate an upgrade instruction for indicating the current version of the vehicle instrument that needs to be upgraded, write the generated upgrade instruction into a preset file, encrypt the preset file using the public key, and then write it into a USB flash drive; The upgrade package is encrypted using a public key on the remote server.

[0027] It should be noted that a remote server stores different versions of various automotive instrument cluster software, and a client connects to the remote server. After the corresponding client software reads the instrument cluster configuration information from a USB flash drive, it sends it to the remote server. The remote server then returns information about all currently available upgradeable versions of the automotive instrument cluster to the client based on the instrument cluster configuration information. Based on the information returned by the remote server, the client selects the current version to be upgraded, downloads the upgrade package corresponding to the current version to the USB flash drive, and then generates an upgrade instruction representing the current version of the automotive instrument cluster to be upgraded. The generated upgrade instruction is written to a preset file, which is encrypted using the public key before being written to the USB flash drive.

[0028] The downloaded upgrade package is encrypted using the public key on the remote server and is no longer encrypted locally on the client. An upgrade policy typically specifies which software can be upgraded to a preset version. The preset file describes the instructions for upgrading the current vehicle instrument cluster.

[0029] Furthermore, in one embodiment, decrypting the upgrade instruction based on the private key to obtain the current version of the vehicle instrument to be upgraded and comparing it with the current vehicle instrument information, and upgrading the vehicle instrument based on the upgrade package according to the comparison result, specifically includes: S401: inserting a USB flash drive containing an upgrade package and a preset file into a USB port of a vehicle meter, decrypting the preset file using the public key to obtain an upgrade instruction, and obtaining the current version of the vehicle meter that needs to be upgraded; S402: Compare the obtained version of the vehicle instrument that needs to be upgraded with the current vehicle instrument information; S403: After the comparison is passed, the upgrade package is decrypted by the private key according to the comparison result, and the vehicle instrument is upgraded based on the decrypted upgrade package.

[0030] Specifically, a USB flash drive containing an upgrade package and a preset file is inserted into the car instrument. The car instrument searches for the preset file and uses the public key to decrypt it to obtain an upgrade instruction, thereby obtaining the current version of the car instrument that needs to be upgraded. The obtained current version of the car instrument that needs to be upgraded is compared with the current car instrument information. After the comparison is passed, the upgrade package is decrypted using the private key, and the car instrument is upgraded based on the decrypted upgrade package.

[0031] Specifically, based on the current vehicle instrument information, it is determined whether the currently upgraded version of the vehicle instrument matches the vehicle instrument: If yes, the comparison passes; If not, the comparison fails.

[0032] The following is a detailed description of the method for implementing the USB flash drive upgrade of the automobile instrument system of the present application.

[0033] First, create a public key and a private key, then create an xxx.txt file. The xxx.txt file contains the instrument configuration information request instruction. Use the public key to encrypt the xxx.txt file to obtain the yyy.txt file. Copy the yyy.txt file to a USB flash drive. Insert the USB flash drive containing the yyy.txt file into the car instrument. After the car instrument detects the USB flash drive, it uses the private key to decrypt the yyy.txt file in the USB flash drive. When the yyy.txt file is successfully decrypted, it generates the yyy.txt file, reads the contents of the yyy.txt file, obtains the instrument configuration information request instruction, executes the corresponding operation, obtains the instrument configuration information and writes it to the USB flash drive, and then unplugs the USB flash drive. The client reads the instrument configuration information from the USB flash drive and establishes a connection between the client and the remote server to send the read instrument configuration information to the remote server. Based on the instrument configuration information, the remote server returns all the currently upgradeable versions of the automobile instrument to the client. The client selects the current version to be upgraded based on the information of all the currently upgradeable versions of the automobile instrument returned by the remote server, downloads the upgrade package corresponding to the current version to be upgraded to the USB flash drive, generates an upgrade instruction using the public key, writes the upgrade instruction into the zzz.txt file and writes it to the USB flash drive; Insert the USB flash drive containing the zzz.txt file and the upgrade package into the car instrument. The car instrument searches for the zzz.txt file and uses the public key to decrypt it to obtain the upgrade instructions, thereby obtaining the current version of the car instrument that needs to be upgraded. The decrypted information is compared with the information of the current instrument. After the comparison is successful, the upgrade package is decrypted using the private key and the decrypted file is updated to the car instrument system.

[0034] The method for implementing USB flash drive upgrade of an automobile instrument system in an embodiment of the present application creates corresponding public and private keys, encrypts a target file containing an instrument configuration information request instruction based on the public key, and writes the encrypted file to a USB flash drive. Then, the target file inserted into the USB flash drive is decrypted based on the private key to obtain the instrument configuration information request instruction and execute it to obtain the instrument configuration information. Then, an upgrade package for the current version of the automobile instrument to be upgraded is obtained based on the obtained instrument configuration information, and an upgrade instruction for indicating the current version of the automobile instrument to be upgraded is generated based on the public key. The upgrade package and the upgrade execution instruction are written to the USB flash drive. Then, the upgrade instruction is decrypted based on the private key to obtain the current version of the automobile instrument to be upgraded and compare it with the current automobile instrument information. According to the comparison result, the automobile instrument is upgraded based on the upgrade package. By adding an authentication mechanism, only versions that meet certain conditions can be upgraded, thereby achieving accurate and effective upgrade of the automobile instrument system based on the USB flash drive.
