[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of systems and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] It should be noted that, in this article, step codes such as S110, S120, etc. are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the sequence. When implementing the step codes, those skilled in the art may execute S120 first and then S110, etc., but these should all be within the scope of protection of this application.

[0049] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] The present application provides a method for flashing vehicle configuration characters, see Figure 1 , the method comprising:

[0051] Step S110, obtaining the vehicle configuration word of the vehicle, and storing the vehicle configuration word in a storage module of the vehicle.

[0052] It can be understood that the corresponding configuration word is stored in the external memory (EEPROM), and at the same time, it is backed up in the internal analog storage space (NVM non-volatile storage area) to avoid the loss of data of this configuration information in the external memory under abnormal operating conditions of the vehicle.

[0053] Furthermore, there is external E2 hardware in the OneBox hardware. This component can store some data that you do not want to be initialized when the power is on and off. The configuration word information can be stored in this area. In addition, there is a virtual memory used to simulate the external E2 and store the backup configuration word information in this area. These two areas have no effect on each other. Therefore, if the hardware is reset due to some abnormal working conditions, we can still read the backup configuration word information.

[0054] Step S120, generating configuration information corresponding to the vehicle according to the vehicle configuration word, and storing the configuration information in the storage module.

[0055] In one embodiment, it further comprises:

[0056] The storage module is divided into an external memory and a virtual memory, the vehicle configuration word and the configuration information are stored in the external memory, and backed up and stored in the virtual memory.

[0057] Specifically, the configuration information stores functional configuration requirement information. Common functional configuration requirement information includes automatic parking function, electronic stability system, hill control system, electronic parking brake system, adaptive cruise control system on or off, as well as wheel speed sensor, tire type, and motor parameter configuration.

[0058] It is understandable that different OEMs will have different functional configuration requirements. Specific configuration words are written through the DID of the 2E service, as well as configuration information written in advance. Based on the configuration information, the corresponding functions and switch configurations are enabled or disabled. During the initialization phase, it is determined whether the configuration words are valid. If valid, the required functions are switched on and off according to the stored functions and switch configuration information.

[0059] Step S130, when the vehicle is powered on, obtaining a required configuration word, and determining whether the vehicle configuration word in the storage module matches the required configuration word.

[0060] In one embodiment, determining whether the vehicle configuration word matches the required configuration word includes:

[0061] Determine whether the first vehicle configuration word in the external memory matches the required configuration word; if not, determine whether the second vehicle configuration word in the virtual memory matches the required configuration word.

[0062] In one embodiment, after determining whether the vehicle configuration word in the storage module matches the required configuration word, the method further includes:

[0063] If the first vehicle configuration word in the external memory and the second vehicle configuration word in the virtual memory do not match the required configuration word, a preset first fault information is reported.

[0064] It can be understood that the function determines whether the configuration word is valid during the power-on initialization phase, thereby determining whether to enable the function and report a fault.

[0065] Specifically, this function is used to obtain the current configuration word number, which is generally used for diagnostic services to read back the current configuration word information. When the configuration word is valid, it should be consistent with the written configuration word. When invalid, a unified fault code should be responded to.

[0066] Step S140: If yes, then configure the corresponding vehicle functions for the vehicle according to the configuration information corresponding to the vehicle configuration word in the storage module, and write the vehicle configuration word into the electronic control unit of the vehicle.

[0067] In one embodiment, configuring the vehicle with a corresponding vehicle function according to the configuration information corresponding to the vehicle configuration word in the storage module includes:

[0068] The functional configuration requirements corresponding to the vehicle configuration word are stored in the configuration information corresponding to the vehicle configuration word; and the corresponding vehicle functions are turned on or off according to the functional configuration requirements in the configuration information.

[0069] Preferably, when the required configuration word is modified, it is detected whether the version information of multiple flash software modules on the electronic control unit are consistent.

[0070] Furthermore, the multiple flash software modules are divided into a definition software module and a communication software module, the version information is defined by the definition software module, and after determining that the version information of the definition software module is inconsistent with that of the communication software module, the preset second fault information is reported.

[0071] It is understandable that since the vehicle configuration function is not a function that can be controlled by a single module, but requires multiple modules to jointly realize its function, if the OEM changes the vehicle configuration requirements (such as adding or reducing the number of configuration words that the software needs to support, adding or deleting configuration items that the software needs to support), resulting in version differences between modules, there will be interaction deviations that fail to meet customer needs.

[0072] Specifically, the version content is defined in the form of a macro in the vehicle configuration module. A script is written through a compile switch in the code of other modules that interact with it to determine whether the version information has been modified. If the vehicle configuration module has been modified, but the compile switch code in the corresponding module has not been modified, an error will be reported when the code is compiled, thereby reminding the person in charge of the module to check whether the modification of the vehicle configuration module has any impact on its own module. After the check, the version information in the compile switch needs to be updated to be consistent with the vehicle configuration module. After this operation, the problem of interaction deviation between modules can be avoided.

[0073] Through the above method, the decoupling of hardware and software can be achieved, and portability can be enhanced, so that OEMs and parts suppliers can shorten the project development cycle and project development management costs, and the assembly and coordination of the controller and the whole vehicle can be more flexible, thereby avoiding the loss of data of this configuration information in the external memory under abnormal working conditions of the whole vehicle, and detecting whether the vehicle model configuration data is abnormal. At the same time, different functions are configured according to different functional configuration requirements, and the interaction deviation between modules is avoided, thereby improving the user's car experience.
