[0054] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0055] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0056] First, let me explain the terms used in this application:

[0057] Electronic Control Unit (ECU): The core control module of an automotive electronic control system, based on a microcontroller (MCU) architecture, is responsible for receiving sensor signals, processing data, and controlling the working state of vehicle subsystems to achieve intelligent management of various vehicle systems.

[0058] Vehicle system controller: This refers to the control module that controls various vehicle systems (such as in-vehicle infotainment system (IVI), advanced driver assistance system (ADAS), etc.). It is responsible for managing and controlling the various subsystems of the vehicle to ensure the safe, efficient and comfortable operation of the vehicle.

[0059] Configuration word: In fields such as computers, microcontrollers, and automotive electronics, this refers to a key data structure used to define hardware or software functional parameters. It is typically stored in non-volatile memory (such as EEPROM, Flash, etc.) as binary bit fields or encoded values. Its core function is to control device functions, adapt to hardware differences, or customize system behavior through specific combinations of configuration words.

[0060] As automobiles become increasingly electronic and intelligent, the functions of electronic control units (ECUs) are becoming more complex, requiring the configuration and management of an ever-growing number of parameters. These parameters are typically stored in the ECU's non-volatile memory in the form of configuration words.

[0061] Since the configuration words contain key parameters about vehicle hardware configuration and function settings, other vehicle systems such as the in-vehicle infotainment system (IVI) and advanced driver assistance system (ADAS) need to read and correctly parse these configuration words from the electronic control unit to adapt to different vehicle models, regions or user preferences and achieve specific functions (such as whether specific hardware exists, whether a certain function is enabled, etc.).

[0062] However, traditional configuration word parsing methods often lack flexibility and scalability, have high development complexity, and cannot meet the needs of rapid iteration and platformization of automotive cockpits.

[0063] To address the aforementioned technical issues, this application provides a vehicle discrete configuration method, electronic device, storage medium, and program product. By configuring multiple segments and concatenating them according to byte order, the vehicle configuration word is parsed, effectively increasing the flexibility and scalability of the configuration word technical solution.

[0064] Below, in conjunction with Figure 1 This application describes the architecture of the vehicle discrete configuration system involved.

[0065] Figure 1 This is a schematic diagram of the architecture of a vehicle discrete configuration system provided in an embodiment of this application. (See attached diagram.) Figure 1 In some embodiments, the vehicle discrete configuration system includes a configuration word cloud 101, a vehicle electronic control unit 102, and at least one vehicle system controller 103. The electronic control unit 102 is communicatively connected to both the configuration word cloud 101 and the at least one vehicle system controller 103.

[0066] Configuration word cloud 101 is used to store discrete logic configuration tables, which include basic information for each configuration word, such as the name, description, number of retries, and multiple discrete data bit field tables.

[0067] Specifically, the name is used to assign a unique identifier to the configuration word, facilitating quick identification; the description briefly explains the core function of the configuration word, including the corresponding hardware module and configuration range; the retry count is the maximum retry threshold when writing the configuration word to the hardware register. When a write fails (e.g., bus busy, hardware not responding), it will automatically retry. If it still fails after the retry count, an error will be reported. For example, if the retry count is set to 3, an error will be reported after 3 retries to ensure the reliability of the configuration; the discrete data bit field table is used to discretely record the independent bit regions (data bit fields are not contiguous) corresponding to different functions in the configuration word. Each data bit field corresponds to the basic information of a configuration item and is the carrier of the configuration word bit structure.

[0068] Specifically, the discrete logic configuration table is generated based on the configuration word summary table. The project products summarize and organize the configuration word summary table (e.g., an Excel spreadsheet) according to the vehicle definition and product selection, and upload it to the configuration word cloud platform 101. The configuration word cloud platform 101 then uses an automated script to parse the configuration word summary table and generate the discrete logic configuration table (e.g., a JSON table).

[0069] The electronic control unit 102 sends a request to the configuration word cloud 101 based on vehicle information such as vehicle model, order, or region. The configuration word cloud 101 determines the logical configuration values ​​(e.g., air conditioning type: automatic, sunroof: present) for each configuration data segment based on the vehicle information carried in the request. Then, the configuration word cloud 101 encodes or packages these logical configuration values ​​into a continuous raw byte stream (i.e., raw configuration byte data) and sends it to the electronic control unit 102. The electronic control unit 102 then discretly writes this raw configuration byte data to a specific non-volatile storage area. Simultaneously, the raw configuration byte data is written in a scattered and discontinuous manner using discrete bit segments.

[0070] The vehicle system controller 103 is used to acquire and parse the original configuration byte data stored in the electronic control unit 102 to obtain the logical configuration value contained in the original configuration byte data, and then adjust the configuration of the vehicle system based on the acquired logical configuration value.

[0071] In this embodiment, the vehicle system controller 103 needs to enable relevant functions based on the vehicle's hardware configuration. Traditional configuration words, when encountering insufficient planned configuration bits during the expansion iteration process, require re-shifting and adding new bits to meet the expansion needs, resulting in poor scalability and inability to meet platform requirements. Therefore, to improve the flexibility and scalability of vehicle configuration word distribution and increase efficiency, an automated tool is used to generate a configuration word mapping table based on the product selection configuration summary table. The current software solution implements parsing, combination, and retry strategies for multiple discontinuous, cross-byte original configuration data segments. Storing configuration data based on discrete, discontinuous byte bits can flexibly handle the shifting risk caused by insufficient planned configuration bits. Expansion can be achieved simply through discrete configuration without modifying the parsing code, effectively improving development and release efficiency.

[0072] It should be noted that, Figure 1 This is merely a schematic diagram of the architecture of a vehicle discrete configuration system provided in an embodiment of this application. This embodiment of the application does not represent... Figure 1 The document does not limit the actual form of the various devices included, nor does it specify the form of the devices. Figure 1 The interaction or connection methods between various devices are limited, and can be set according to actual needs in the specific application of the technical solution.

[0073] Based on the aforementioned vehicle discrete configuration system architecture, the technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0074] Figure 2 This is a flowchart illustrating a vehicle discrete configuration method provided in an embodiment of this application. (See attached diagram.) Figure 2 In some embodiments, this vehicle discrete configuration method is applied to the vehicle's onboard system controller, which communicates with the electronic control unit. The specific process includes the following steps:

[0075] S201, Obtain the original configuration byte data stored in the electronic control unit; wherein, the original configuration byte data includes configuration data segments discretely stored in the electronic control unit through at least one data bit segment, and the configuration data segments include the logical configuration values ​​of the corresponding configuration items.

[0076] Optionally, the acquisition of raw configuration byte data specifically includes:

[0077] Step 1: Send a configuration data request to the electronic control unit; wherein, the configuration data request is used to request the electronic control unit to send raw configuration byte data to the vehicle system controller.

[0078] Specifically, the vehicle system controller sends a configuration data request to the electronic control unit, requesting the electronic control unit to send the stored raw configuration byte data to the vehicle system controller.

[0079] Specifically, the configuration data request carries information such as a unique identifier, timestamp, data range, and authentication information.

[0080] Specifically, when the vehicle system controller and the electronic control unit communicate via the CAN channel, the configuration data request uses a CAN diagnostic request frame.

[0081] Step 2: Receive the raw configuration byte data transmitted by the electronic control unit.

[0082] In this process, after the electronic control unit sends the raw configuration byte data to the vehicle system controller, the vehicle system controller receives the raw configuration byte data.

[0083] Optionally, before sending the configuration data request to the electronic control unit, the following may also be included:

[0084] Step 1: Listen to the raw configuration byte data stored in the electronic control unit.

[0085] The vehicle system controller continuously monitors the original configuration byte data stored in the electronic control unit to check whether the original configuration byte data stored in the electronic control unit has changed.

[0086] Specifically, the vehicle system controller can use techniques such as polling, event-driven mechanisms, and message queues to monitor the raw configuration bytes stored in the electronic control unit. Polling detects data changes by periodically and proactively querying the data source, a simple technique to implement. Event-driven mechanisms capture changes in real time by listening to events proactively triggered by the data source, offering fast response times and low resource consumption. Message queues allow producers to push messages to the queue when data changes, and consumers subscribe to the queue to receive change notifications, decoupling system components and supporting asynchronous processing.

[0087] Step 2: When a change is detected in the original configuration byte data, a configuration data request is sent to the electronic control unit.

[0088] If the original configuration byte data stored in the electronic control unit changes, the vehicle system controller sends a configuration data request to the electronic control unit to request the latest original configuration byte data.

[0089] S202, parse the original configuration byte data to obtain the logical configuration data.

[0090] Optionally, the acquisition of logical configuration data specifically includes:

[0091] Step 1: Traverse the original configuration byte data and extract the logical configuration values ​​of the corresponding configuration items for each configuration data fragment.

[0092] Step 2: Concatenate the logical configuration values ​​of each configuration item to obtain the logical configuration data.

[0093] This involves combining the various logical configuration values ​​extracted from the original configuration byte data into a meaningful and complete logical configuration data.

[0094] Optionally, the extraction of logical configuration values ​​for configuration items corresponding to each configuration data fragment specifically includes:

[0095] Step 1: Traverse the original configuration byte data to obtain at least one configuration data fragment.

[0096] Step 2: For each configuration data fragment, traverse the configuration data fragments and extract the logical configuration values ​​of the corresponding configuration items in the configuration data fragments.

[0097] Specifically, the structure of the original configuration byte data is traversed through a double loop. The starting byte, starting bit, and number of bits occupied by each configuration word in the original configuration byte data are extracted. The byte is located through shift and mask operations. Based on the starting bit and the number of bits to be extracted in the byte, the logical configuration value represented by the current data bit segment is accurately extracted.

[0098] Optionally, the basic information of the configuration item includes multi-segment concatenation rules, which concatenate the logical configuration values ​​of each configuration item to obtain logical configuration data. This includes: for each configuration data segment, concatenating the logical configuration values ​​of the corresponding configuration items based on the multi-segment concatenation rules of the configuration item to obtain logical configuration data.

[0099] Among them, the correct concatenation of multiple logical configuration values ​​is achieved through the multi-segment concatenation rules of configuration items.

[0100] Optionally, before parsing the raw configuration byte data, the method further includes: converting the raw configuration byte data into a data structure that can be processed by the vehicle system controller.

[0101] This involves converting external, human-readable configuration rules into data structures that can be efficiently processed by the internal program of the vehicle system controller, thus preparing the data for subsequent rapid lookup and parsing of each logical configuration item.

[0102] S203, convert the logical configuration data, obtain string configuration data and store it; wherein, the string configuration data includes the string configuration value of at least one configuration item, and the string configuration value is used for the application or service configured by the vehicle system controller to call, so as to adjust the configuration parameters of the vehicle system according to the string configuration value.

[0103] The vehicle system controller calls an interface to convert logical configuration data into string configuration data and sets the converted string values ​​to the corresponding storage system for exposure to upper-layer applications or services. This allows upper-layer applications to adjust their behavior based on the string configuration data, thereby achieving personalization and adaptation of the vehicle's in-vehicle system functions.

[0104] In this embodiment, configuration data is stored based on discrete, non-contiguous byte bits, providing a solution for parsing vehicle configuration words based on multi-segment configuration and byte-order concatenation. This approach flexibly handles the shift risk caused by insufficient planned bits in the configuration word, and expansion can be achieved simply through discrete configuration without modifying the parsing code, thus improving development and release efficiency. Furthermore, based on discrete storage of configuration words, it effectively solves the problem of how to combine multiple scattered, non-contiguous bit segments from the original data of the electronic control unit into logical configuration data, increasing the flexibility and scalability of the configuration word technology solution.

[0105] Figure 3 A flowchart illustrating another vehicle discrete configuration method provided in this application embodiment is shown below. Figure 3 In some embodiments, this vehicle discrete configuration method is applied to the vehicle's electronic control unit, which is communicatively connected to at least one on-board system controller. The specific process includes the following steps:

[0106] S301, Obtain the raw configuration byte data imported from the configuration word cloud; wherein, the configuration word cloud is used to store the discrete configuration logic table generated based on the configuration word summary table, and the raw configuration byte data is extracted from the discrete configuration logic table according to the vehicle information.

[0107] The project products summarize the configuration words into an Excel summary table based on the vehicle definition and product selection. An automated script is used to parse the summary table to generate a logical table EcuTable.json, which contains the basic information of each configuration word (name, description, number of retries, and multiple scattered, non-contiguous data segment tables).

[0108] S302, the original configuration byte data is discretely written into the non-volatile storage area of ​​the electronic control unit; wherein, the original configuration byte data includes configuration data segments discretely stored in the electronic control unit through at least one data bit segment, the configuration data segments include the logical configuration values ​​of the corresponding configuration items, and the original configuration byte data is used for the vehicle system controller to read and parse.

[0109] The configuration word settlement system determines the specific value of each configuration item (e.g., air conditioning type = automatic, sunroof = present) based on the needs of a specific vehicle model, order, or region. Then, according to the physical location (byte index, bit offset, bit length) of each configuration item (and its segments) defined in the summary table in the ECU storage, these logical values ​​are "encoded" or "packed" into a continuous raw byte stream. During the EOL vehicle generation process, diagnostic tools write the data to a specific non-volatile storage area of ​​the first system.

[0110] Specifically, the EOL (End of Line) vehicle production process is the final checkpoint in automobile manufacturing to ensure product quality. Its core is to conduct comprehensive verification of the assembled vehicle through systematic testing and adjustments, ultimately ensuring that every vehicle off the production line meets safety and performance standards.

[0111] Optionally, the original configuration byte data can be discretely written to the non-volatile storage area of ​​the electronic control unit, including: using a diagnostic tool to discretely write the original configuration byte data to the non-volatile storage area of ​​the electronic control unit.

[0112] The core function of writing data into the non-volatile storage area of ​​the vehicle's electronic control unit (ECU) through diagnostic tools is to achieve persistent storage and flexible configuration of critical data, while improving diagnostic efficiency, ensuring system security, and adapting to the diverse needs throughout the vehicle's life cycle.

[0113] In this embodiment, the configuration word scheme is based on an extension scheme of the same configuration word for multiple electronic control units, which can effectively avoid maintaining multiple configuration word schemes and realize a systematic configuration word distribution, configuration, parsing and storage scheme across platforms and vehicle models.

[0114] Figure 4 A flowchart illustrating another vehicle discrete configuration method provided in this application embodiment is shown below. Figure 4 In some embodiments, the vehicle discrete configuration method is applied to a vehicle discrete configuration system, which includes a configuration word cloud, an electronic control unit of the vehicle, and at least one on-board system controller. The process includes the following steps:

[0115] S401, Configuration word cloud receives configuration word summary table.

[0116] S402, a discrete configuration logic table generated by the configuration word cloud based on the configuration word summary table.

[0117] S403, the configuration word cloud extracts the original configuration byte data from the discrete configuration logic table based on the vehicle information.

[0118] S404, the configuration word cloud imports the discrete configuration logic table into the electronic control unit.

[0119] S405, the electronic control unit uses diagnostic tools to discretely write the original configuration byte data into a non-volatile memory area.

[0120] S406, the vehicle system controller listens to the raw configuration byte data stored in the electronic control unit.

[0121] S407: When the vehicle system controller detects a change in the original configuration byte data, it sends a configuration data request to the electronic control unit.

[0122] S408, the vehicle system controller receives raw configuration byte data transmitted by the electronic control unit.

[0123] S409, the vehicle system controller traverses the original configuration byte data and extracts the logical configuration values ​​of the corresponding configuration items for each configuration data segment.

[0124] S410, the vehicle system controller concatenates the logical configuration values ​​of each configuration item to obtain logical configuration data.

[0125] S411, the vehicle system controller converts the logical configuration data, obtains the string configuration data, and stores it.

[0126] In this embodiment, it should be noted that, Figure 4 The implementation principles and technical effects of each step in the process shown can be found in the previous text. Figure 2 and Figure 3 The relevant explanations will not be repeated here.
