Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.

The association relationship of the associated objects is described by "and / or", which means that there can be three relationships, for example: A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone.

Therefore, the technical features limited by "first" and "second" can explicitly or implicitly include at least one of the features.

[0045] Figure 1 FIG. 1 shows a method flowchart of an embodiment of the modification method of the internal parameters of the intelligent cockpit controller provided by the present application, Figure 1 As shown in FIG. 1, the modification method of the internal parameters of the intelligent cockpit controller includes the following steps.

[0046] S101, verifying an unlocking file of the intelligent cockpit controller based on the factory data of the vehicle; the unlocking file is generated based on the vehicle information corresponding to the intelligent cockpit controller with the to-be-modified parameters;

[0047] S102, when the verification passes, determining a parameter list to be modified of the intelligent cockpit controller based on the unlocking file;

[0048] S103, modifying parameters of the cockpit controller based on the parameter list to be modified and an input activation code; the activation code is generated based on a random code and a confusion code.

[0049] Optionally, the unlocking file can be stored in a U disk or other storage medium, and the unlocking file is used to verify the vehicle cockpit controller whose parameters are to be modified. The U disk can be used to write and communicate with the cockpit controller to complete the start of the writing function. The vehicle cockpit controller includes a central control screen, and the central control screen can be used to select or fill in the vehicle configuration to determine the internal parameters that need to be modified.

[0050] In S101, vehicle information such as a VIN code, a controller serial number, a controller vendor code, etc. can be collected. An unlocking file is generated based on vehicle information corresponding to the intelligent cockpit controller whose parameters are to be modified, the unlocking file contains a VIN code, a controller serial number, a controller vendor code, a software version number, an unlocking flag, and various parameter information, and is encrypted and saved in a fixed format to obtain an encrypted unlocking file.

[0051] The information in the unlocking file is compared and verified with the factory data of the vehicle to ensure the authenticity and validity of the unlocking file.

[0052] In S102, when the verification passes, the unlocking file is read from the U disk or other storage medium, and each item of information in the unlocking file is parsed according to a fixed format to extract a parameter list to be modified. A parameter list to be modified is generated based on the parsed parameter information, and the list contains all parameters to be modified and their corresponding modification values.

[0053] In S103, an activation code is generated using a random code and a preset confusion code, the generated activation code is input on the central control screen, and the correctness of the activation code needs to be verified before the parameter modification operation is performed during the modification process. The parameter list to be modified is displayed on the central control screen to facilitate the modification of the parameters. After the parameter modification is completed, the new parameter values are saved to the internal storage of the intelligent cockpit controller to complete the modification.

[0054] The content of the U disk unlocking file is matched with the vehicle parameters, and the parameter change options are generated on the specific interface of the central control screen to prevent the change from failing due to parameter input errors.

[0055] Compared with the prior art, the modification method of internal parameters of the intelligent cockpit controller provided by the embodiment of the application generates an encrypted unlocking file according to vehicle information corresponding to the intelligent cockpit controller of the to-be-modified parameter, verifies the unlocking file of the intelligent cockpit controller through the factory data of the vehicle to ensure the authenticity and validity of the unlocking file, determines a to-be-modified parameter list according to the unlocking file after the verification passes, and modifies the parameters of the cockpit controller according to the input activation code and the to-be-modified parameter list, so that the internal parameters of the controller are conveniently and safely modified through the central control screen of the intelligent cockpit without the need of special host computer software and diagnostic instrument tools, and the safety and timeliness are improved.

[0056] In some embodiments of the application, the unlocking file comprises:

[0057] The VIN code, the controller serial number, the controller supplier code, the software version number, the unlocking flag, and the parameter information.

[0058] When the vehicle configuration is changed or the vehicle intelligent cockpit controller is replaced, the unlocking file is edited through the vehicle information that needs to be changed.

[0059] The unlocking file comprises the VIN code, the controller serial number, the controller supplier code, the software version number, the unlocking flag, and the parameter information, and the encrypted unlocking file is generated in a fixed format.

[0060] The unlocking file is sent to the on-site operator, the on-site operator copies the unlocking file to a U disk, and the U disk is inserted into the USB interface of the vehicle, and the cockpit controller reads the U disk unlocking file.

[0061] In some embodiments of the application, the verification of the unlocking file of the intelligent cockpit controller based on the factory data of the vehicle comprises:

[0062] The factory data is compared with the VIN code, the controller serial number, and the controller supplier code.

[0063] When the factory data is consistent with the VIN code, the controller serial number, and the controller supplier code, the verification passes.

[0064] The first line of VIN code is read according to a fixed format and saved into a variable vinCode in the memory, the second line of controller serial number is read and saved into a variable device SerialNumber in the memory, the third line of controller manufacturer code is read and saved into a variable manufacturerCode in the memory, the fourth line of controller software version number is read and saved into a variable softVersion in the memory, the fifth line of unlock flag is read and saved into a variable lockFlag in the memory, and the sixth line of parameter information is read and saved into an array parameter[] in the memory.

[0065] After the controller saves the unlock file, the VIN code, the controller serial number and the controller manufacturer code read from the data saved by the controller when leaving the factory are compared with vinCode, SerialNumber and manufacturerCode.

[0066] When the VIN code, the controller serial number and the controller manufacturer code read from the data saved by the controller when leaving the factory are consistent with vinCode, SerialNumber and manufacturerCode saved in the memory, the verification is passed. Otherwise, the verification is not passed.

[0067] In some embodiments of the present application, the determination of the to-be-modified parameter list corresponding to the intelligent cockpit controller based on the unlock file comprises:

[0068] Based on the software version number, a list of modifiable parameters corresponding to each version is generated.

[0069] Based on the parameter information and the list of modifiable parameters, the to-be-modified parameter list is generated.

[0070] In some embodiments of the present application, the generation of the to-be-modified parameter list based on the parameter information and the list of modifiable parameters comprises:

[0071] Based on the parameter information, a to-be-modified parameter and a modification value of the to-be-modified parameter are determined.

[0072] The to-be-modified parameter and the modification value are compared with the list of modifiable parameters to generate the to-be-modified parameter list.

[0073] After the verification is passed, the controller generates a list of all parameters that can be changed according to the software version number softVersion, then generates a parameter list file that needs to be changed according to the parameters of the array parameter[], and sets the unlock flag of the controller to 1.

[0074] After the above steps are completed inside the controller, the central control screen pops up a write-protect unlocking file confirmation interface, and after clicking confirmation, the unlocking file reading and unlocking are completed.

[0075] Exemplarily, the controller first reads the softVersion field in the unlocking file to determine the software version of the current vehicle. According to the identified software version, the controller accesses the parameter library or configuration database inside it, which contains a list of changeable parameters corresponding to each software version.

[0076] According to the query result, a list of all changeable parameters of the current software version, i.e., a modifiable parameter list, is generated. The modifiable parameter list includes information such as the name, type, default value, and acceptable modification range of the parameter.

[0077] The controller traverses the parameter[] array in the unlocking file, which contains parameters to be modified and modification values of the parameters to be modified. The parameter to be modified is the parameter that the user wants to modify, and the modification value is the desired value after modification.

[0078] For each parameter in parameter[], a matching item is searched in the generated changeable parameter set. If a matching item is found and the modification value is within the acceptable modification range, the parameter is determined to be a parameter to be modified. According to all the parameters to be modified and the modification values, a list of parameters to be modified is generated.

[0079] The modification method of the internal parameters of the intelligent cockpit controller provided by the embodiment of the application can enable anyone to modify the internal parameters of the controller according to the instructions without the need for a special host computer software and a diagnostic instrument tool. Meanwhile, because the controller reads the U disk unlocking file and verifies the vehicle parameters, the operation interface of the central control screen determines the modification range of the internal parameters of the controller according to the parameters of the unlocking file, and the on-site operator only needs to select, thereby preventing modification errors and avoiding the case that the vehicle cannot be modified due to CAN bus failure.

[0080] In some embodiments of the application, the activation code is determined by the following method:

[0081] The random code and the preset confusion code are confused to generate a seed code;

[0082] The seed code is encrypted to generate the activation code.

[0083] In some embodiments of the application, modifying the parameters of the cockpit controller based on the list of parameters to be modified and the input activation code includes:

[0084] When the activation code is verified, the list of parameters to be modified is displayed on the central control screen;

[0085] Based on the list of parameters to be modified displayed on the central control screen, the parameters of the cockpit controller are modified.

[0086] After unlocking, the controller parameter modification menu will appear in the menu of the central control screen. Click the modify parameter menu, an 8-digit random code will appear and you will be prompted to enter the password.

[0087] A seed code (seed) is generated by mixing an 8-bit random code with a fixed 8-bit preset obfuscation code. The seed is encrypted using an encryption algorithm to generate an activation code (key). Enter the key into the password field on the central control screen. After unlocking, enter the parameter modification interface, follow the prompts to enter the parameters, and click OK to save the parameters.

[0088] After completing the parameter modification, the controller will automatically restart and initialize. At the same time, after the restart is completed, the controller parameter modification function will be locked again. You need to flash the unlock file again before you can enter the parameter modification interface again.

[0089] The method for modifying the internal parameters of the intelligent cockpit controller provided by an embodiment of the present invention adopts a double encryption scheme, namely, the USB flash drive encrypted file unlocks the central control change interface and the central control screen generates a parameter change activation password based on the USB flash drive unlocking file, which further improves the security of parameter modification.

[0090] Figure 2 This is a structural diagram of an embodiment of a system for modifying internal parameters of an intelligent cockpit controller provided by the present invention, as shown in FIG. Figure 2 As shown, the system for modifying the internal parameters of the intelligent cockpit controller includes: an unlock file, used to verify the vehicle cockpit controller whose parameters need to be modified; a USB flash drive, used for flashing and communicating with the cockpit controller to enable the flashing function; and a central control screen, used to select or enter vehicle configuration and determine the internal parameters that need to be modified.

[0091] The present invention uses a universal USB flash drive and a large screen that comes with the smart cockpit. After the USB flash drive is plugged in, the smart cockpit controller reads the vehicle-specific unlocking file in the USB flash drive, matches the controller serial number and the vehicle VIN code with the vehicle parameters, determines the parameters and range that need to be changed, selects the corresponding vehicle parameters through the central control screen operation interface, and then saves the data to the controller memory to complete the internal parameter change of the controller.

[0092] Figure 3 This is a second method flow chart of an embodiment of the method for modifying the internal parameters of the intelligent cockpit controller provided by the present invention, as shown in FIG. Figure 3 As shown, the method for modifying the internal parameters of the intelligent cockpit controller provided by the present invention includes:

[0093] When the user vehicle needs to temporarily change the internal parameters of the controller due to replacement of a new controller or due to other configuration changes of the vehicle, the on-site operator contacts the relevant engineer, and the engineer edits an unlocking file through vehicle information.

[0094] The unlocking file includes VIN code, controller serial number, controller supplier code, software version number, unlocking flag and other information, and the encrypted unlocking file is generated in a fixed format, and the controller unlocking file is sent to the on-site service personnel.

[0095] After the on-site operator obtains the unlocking file, the unlocking file is copied to a U disk, and the U disk is inserted into the USB interface of the vehicle, and the key is screwed to the ON gear to power on. After the cabin controller recognizes the U disk, the unlocking file confirmation interface is popped up.

[0096] After clicking confirmation, the controller reads the unlocking file in the U disk into the controller memory, extracts the VIN code, controller serial number, controller supplier code, software version number, unlocking flag and parameter information in the symbol <> and assigns them to the vinCode, SerialNumber, manufacturerCode, softVersion, parameter and other parameter variables respectively.

[0097] At the same time, the saved vehicle information and controller information of the controller are verified, and when the vinCode, SerialNumber, manufacturerCode and vehicle information are verified successfully, all modified parameter list files are generated according to the controller version for subsequent display on the central control screen.

[0098] On the other hand, when the unlocking file parameters are correct, the unlocking flag is set to the unlocking state. At this time, the unlocking confirmation option is popped up in the central control screen, and the parameter modification interface is unlocked by clicking confirmation.

[0099] After unlocking, a controller parameter modification menu appears in the menu of the central control screen, and by clicking the modification parameter menu, an 8-digit random code appears and prompts to input the activation code. At this time, the on-site operator sends the random code to the relevant engineer.

[0100] The engineer mixes the 8-digit random number with the fixed 8-digit mixed code to generate a seed code, and inputs the seed code into the encryption tool specified before to generate an activation code, and sends the random code to the on-site operator.

[0101] After the on-site operator inputs the activation code in the input activation code interface of the central control screen and clicks confirmation, if the activation code is correct, the parameter modification interface is entered.

[0102] The user inputs relevant parameters on the central control screen interface according to the vehicle configuration, clicks to confirm, and the controller internally checks according to the activation code, unlocking state, current vehicle speed and other states, and if all conditions are met, the parameter modification is prompted to be successful, and it is prompted to automatically restart after 3s.

[0103] The controller completes parameter modification and automatically restarts the controller, and after restarting, the controller returns to the locked state, and if the parameters need to be modified again, the above operations need to be completed again.

[0104] The application adopts the input function of the central control large screen and the USB box of the intelligent cockpit, adopts a double encryption scheme without a special host computer, and conveniently and safely modifies the internal parameters of the controller through the unlocking file, U disk and central control screen interface, without a special host computer tool, safe and fast, and can prevent malicious cracking and tampering.

[0105] The application solves the problem of modifying the internal parameters of the intelligent cockpit controller without a diagnostic instrument or vehicle bus problem, solves the problem of requiring professional after-sales service personnel to rush to the scene for processing, requiring an additional host computer, high cost, and time efficiency that cannot be met, and solves the risk of the service personnel changing and changing errors at will through the host computer.
