[0034] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0035] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0036] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in the present invention are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and corresponding operation entrances shall be provided for users to choose to authorize or refuse.

[0037] With the rapid development of vehicle intelligence, the domain controller of the vehicle integrates more and more application algorithms corresponding to different functions. Specifically, based on the improvement of the computing power of the domain controller and the sufficient reservation of static resources, the application algorithm logic of the vehicle's power system, braking system, steering system, air conditioning thermal management system and suspension system can be gradually deployed in the domain controller to greatly reduce the hardware cost of traditional solutions and realize the self-development of core algorithms. The integration and deployment of various application algorithms in the domain controller involves the management of different calibration data, such as power software, based on different battery pack capacities, different calibration data based on different emission sizes, different calibration data based on different driving forms, different calibration data based on different braking styles of the braking system, different calibration data based on different steering operation modes of the driver, and different calibration data based on the air conditioning heat pipe system based on the circuit solution of thermal management.

[0038] At present, for different calibration data, a version of basic software is usually provided. Based on the basic software, multiple versions of calibration software are provided for different vehicle configurations of different models. When the vehicle is debugged, the difference calibration data is updated according to different vehicles. However, there are problems of numerous versions and complex management when processing calibration data in the above manner. In addition, in the related art, the collected multiple versions of calibration software can also be merged with the main software, and finally multiple versions of software for different vehicle configurations are released. However, the above-mentioned related technology also has problems of numerous versions and complex management, which is a huge management problem for version writing personnel and over-the-air (OTA) upgrade personnel. In particular, after the domain controller integrates multiple applications, the different calibration data combinations involved may be as many as dozens or even hundreds. Accordingly, various software versions will be generated, resulting in too high management costs and serious impact on project progress. Considering that software management is a complex and error-prone matter in project development, an effective solution for calibration data processing is urgently needed to solve the dilemma caused by a large number of versions to project development.

[0039] Based on the above problems, the present invention provides a calibration data processing method, which uniformly manages different calibration data corresponding to the configuration of the same vehicle model through a differential calibration data table, wherein the data in the differential calibration data table is obtained by integrating the different calibration data corresponding to the configuration of the vehicle model using a differential method, so as to obtain the target calibration data corresponding to the target vehicle based on the data in the differential calibration data table and the basic calibration data, thereby realizing unified management of different calibration data of vehicles of the same vehicle model, solving the problems of numerous versions and complex management caused by multiple calibration data, and being able to greatly avoid the management problems caused by multiple versions in debugging, production and subsequent software upgrades. Through pure software design, seamless management of multiple calibration data can be realized without increasing hardware costs.

[0040] It can be seen that the calibration data processing method provided by the present invention can be used to manage multiple different calibration data in the same vehicle model software, that is, one vehicle model will only have one software package, solving the management problem caused by multiple calibration data. Under the trend of integrating multiple application algorithms into domain controllers, since calibration data is various, the calibration data processing method provided by the present invention can effectively solve the problem of multiple versions.

[0041] In the following, the application scenario of the solution provided by the present invention is firstly described by way of example.

[0042] Figure 1 Schematic diagram of an application scenario provided by an embodiment of the present invention. Figure 1 As shown, in this application scenario, the domain controller of the vehicle integrates application algorithms corresponding to multiple different functions, such as application algorithms corresponding to the vehicle's power system, braking system, steering system, air conditioning thermal management system, and suspension system. After the domain controller is powered on, according to the calibration data processing method provided in an embodiment of the present invention, the target calibration data corresponding to different configurations of the vehicle model is determined, and the target calibration data is loaded.

[0043] It should be noted that Figure 1 This is only a schematic diagram of an application scenario provided by an embodiment of the present invention. Figure 1 does not limit the equipment included in Figure 1 The positional relationship between the devices is limited.

[0044] The technical solution of the present invention is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0045] Figure 2 The flowchart of the calibration data processing method provided by one embodiment of the present invention. The calibration data processing method can be executed by software and / or hardware devices. For example, the hardware device can be a calibration data processing device. The calibration data processing device can be an electronic device or a processing chip in an electronic device. Specifically, the electronic device can be a domain controller of a vehicle. Figure 2 As shown, the method of the embodiment of the present invention includes:

[0046] S201. In response to a calibration data loading instruction for a target vehicle, obtain a configuration identifier corresponding to a model of the target vehicle.

[0047] It can be understood that the calibration data of the vehicle is a set of parameters used to optimize and control the performance of each system of the vehicle. These data are carefully adjusted during the vehicle development and testing phase to ensure that the performance, efficiency, emissions and driving experience of the vehicle under various working conditions meet the expected standards. In this embodiment, the configuration identifier corresponding to the model of the target vehicle is a configuration data item description (Data Item Description, DID), which is used to identify a specific data item stored in the domain controller of the vehicle. The configuration identifier (configuration DID) is usually written offline by the factory, which does not bring additional work, and is used to adaptively match the corresponding calibration data to solve the problem that different models of configuration require different calibration data. For vehicles of the same model, the configuration of the vehicle includes, for example, battery pack capacity and drive type, etc. The configuration identifier (configuration DID) is used to identify the calibration data corresponding to the configuration of the vehicle, for example, the battery pack capacity is 55 ampere hours (Ah), and the drive type is two-wheel drive. Exemplarily, after the domain controller of the target vehicle is powered on, a calibration data loading instruction for the target vehicle is triggered, and according to the calibration data loading instruction, the configuration identifier corresponding to the model of the target vehicle is obtained.

[0048] S202. According to the configuration identifier, the calibration data to be modified and the target data value corresponding to the calibration data to be modified are obtained from the difference calibration data table, wherein the data in the difference calibration data table is obtained by integrating different calibration data corresponding to the configuration of the vehicle model using a difference method.

[0049] Exemplarily, after obtaining the configuration identifier (configuration DID) corresponding to the model of the target vehicle, the difference calibration data table can be queried according to the configuration identifier to obtain the calibration data to be modified and the target data value corresponding to the calibration data to be modified from the difference calibration data table.

[0050] Optionally, the data in the difference calibration data table is obtained by: obtaining the difference calibration data between the different calibration data corresponding to the configuration of the vehicle model and the basic calibration data; integrating the difference calibration data using a differential method, and storing them in the difference calibration data table to obtain the data in the difference calibration data table.

[0051] Exemplarily, the basic calibration data can also be understood as reference calibration data, which is used to determine the difference calibration data corresponding to the configuration of the same vehicle model, and includes the initial value of the predefined calibration data. For example, the basic calibration data includes 100 calibration data, and the 100 calibration data corresponding to the configuration of the target vehicle model can be compared with the 100 basic calibration data, wherein the identification (such as the name) of the calibration data is the same, and the data value of the calibration data may be different, therefore, the difference calibration data with different data values ​​can be determined, for example, the difference calibration data is determined to be 3 calibration data, and the remaining 97 calibration data are the same, and the difference calibration data is the calibration data to be modified.

[0052] Further, optionally, obtaining the difference calibration data between the different calibration data corresponding to the configuration of the vehicle model and the basic calibration data may include: comparing the basic calibration data and the different calibration data corresponding to the configuration of the vehicle model by numerically comparing the data at the same address according to a memory block of a preset size, and obtaining the difference calibration data between the different calibration data corresponding to the configuration of the vehicle model and the basic calibration data.

[0053] Exemplarily, the memory block of the preset size is, for example, a unit data block of 4 kilobytes (K). In this embodiment, for the 100 calibration data and 100 basic calibration data corresponding to the configuration of the target vehicle's model, a method of numerically comparing the data at the same address according to the memory block of the preset size can be adopted to compare the 100 basic calibration data and the 100 calibration data corresponding to the configuration of the target vehicle's model, and the calibration data with different data values ​​can be screened out, so that the difference calibration data between the calibration data corresponding to the configuration of the model and the basic calibration data can be obtained, so as to integrate the unified calibration data and realize the normalization of multiple calibration data. It can be understood that comparing the calibration data according to the memory block, rather than comparing according to a single calibration data, can greatly improve the efficiency of comparison and search, and avoid the time waste caused by searching for calibration data one by one. Figure 3 A schematic diagram of the integrated processing of multiple calibration data provided by an embodiment of the present invention. Figure 3 As shown, for different calibration data corresponding to different configurations of vehicles of the same model, in order to achieve unified management of software, the basic calibration data (i.e., substrate) can be pre-defined, and the difference calibration data can be automatically identified by comparing the difference between other calibration data and the substrate. On the basis of the original calibration space, the difference calibration data can be placed behind it (i.e., A difference table, B difference table, and C difference table), and a data table containing basic calibration data and difference calibration data can be obtained for overview. Among them, the identification of difference calibration data is not indexed and identified in sequence according to a single calibration data, but indexed and identified according to a memory block of a preset size, which can improve the recognition speed and reduce the waste of integration time.

[0054] In this embodiment, after the difference calibration data (calibration data to be modified) is determined, the difference calibration data may be integrated using a differential method and stored in a difference calibration data table to obtain data in the difference calibration data table.

[0055] Exemplarily, the differential method is used to integrate the difference calibration data, which can avoid wasting code space and causing new resource problems. After determining the difference calibration data, the differential method can be used to integrate the difference calibration data and store it in the difference calibration data table to obtain the data in the difference calibration data table. Among them, the difference calibration data table may include, for example, a first difference data table, a second difference data table, and a third difference data table; the first difference data table is used to store the starting address information of the difference calibration data of a certain configuration and the number of difference calibration data; the second difference data table is used to store the flash memory starting address of the difference calibration data, the random access memory (Random Access Memory, RAM) starting address and the length of the difference calibration data; the third difference data table is used to store the real data value of the difference calibration data. For how to obtain the calibration data to be modified and the target data value corresponding to the calibration data to be modified from the above three difference data tables according to the configuration identifier, please refer to the subsequent embodiments.

[0056] S203: Replace the initial value corresponding to the calibration data to be modified in the basic calibration data with the target data value to obtain the target calibration data corresponding to the target vehicle.

[0057] In this step, after obtaining the calibration data to be modified and the target data value corresponding to the calibration data to be modified, the initial value corresponding to the calibration data to be modified in the basic calibration data can be replaced with the target data value, thereby obtaining the target calibration data corresponding to the target vehicle.

[0058] S204: Load target calibration data.

[0059] In this step, after obtaining the target calibration data corresponding to the target vehicle, the target calibration data is loaded, thereby realizing the seamless management of multiple calibration data and solving the problem of multiple versions and complex management.

[0060] The calibration data processing method provided by the embodiment of the present invention obtains the calibration data to be modified and the target data value corresponding to the calibration data to be modified from the difference calibration data table according to the configuration identifier corresponding to the model of the target vehicle. The data in the difference calibration data table is obtained by integrating the different calibration data corresponding to the configuration of the model using the differential method, thereby replacing the initial value corresponding to the calibration data to be modified in the basic calibration data with the target data value, and obtaining the target calibration data corresponding to the target vehicle, thereby realizing unified management of different calibration data of vehicles of the same model, solving the problems of numerous versions and complex management caused by multiple calibration data, improving the efficiency of version management, and not increasing hardware costs.

[0061] Figure 4FIG. 1 is a flow chart of a calibration data processing method provided by another embodiment of the present invention. Based on the above embodiment, the present invention further describes the calibration data processing. Figure 4 As shown, the method of the embodiment of the present invention may include:

[0062] S401 . In response to a power-on instruction, write basic calibration data into a calibration area of ​​a RAM.

[0063] Exemplarily, after the domain controller of the vehicle is powered on, the predefined basic calibration data may be written into the calibration area of ​​the RAM.

[0064] S402: In response to a calibration data loading instruction for a target vehicle, obtain a configuration identifier corresponding to a model of the target vehicle.

[0065] The detailed description of this step can be found in Figure 2 The relevant description of S201 in the illustrated embodiment will not be repeated here.

[0066] S403: Analyze the calibration area and obtain basic calibration data.

[0067] In this step, the calibration area may be parsed to obtain basic calibration data from the calibration area, where the basic calibration data includes an initial value of the calibration data.

[0068] In a possible implementation manner, the difference calibration data table includes a first difference data table, a second difference data table and a third difference data table. Therefore, in the embodiment of the present invention, Figure 2 The step S202 may further include the following three steps S404 to S406:

[0069] S404. According to the configuration identifier, obtain the calibration data to be modified, the starting address of the calibration data to be modified, and the quantity of the calibration data to be modified from the first difference data table.

[0070] Exemplarily, after obtaining the configuration identifier corresponding to the model of the target vehicle, the calibration data to be modified, the starting address of the calibration data to be modified, and the number of calibration data to be modified can be obtained from the first difference data table according to the configuration identifier. For example, the calibration data to be modified may be the battery pack capacity and the drive type, the starting address of the calibration data to be modified is the starting address of the battery pack capacity, and the number of calibration data to be modified is 2. Table 1 shows the information contained in the first difference data table; wherein different information indexes (such as information index 1) represent different configuration identifiers of the vehicle. Taking information index 1 as an example, information index 1 corresponds to multiple calibration data to be modified (difference calibration data), the starting address of each calibration data to be modified (difference calibration data), and the number of calibration data to be modified (difference calibration data).

[0073] Through the first difference data table, data can be quickly searched, and the number of query data under the same configuration can be quickly located, and the starting address of the difference calibration data can be quickly indexed in the next step.

[0074] S405 . Obtain the flash memory start address and the RAM start address of the calibration data to be modified from the second difference data table according to the start address and the quantity.

Table 2 takes the difference calibration data corresponding to the information index 1 in Table 1 as an example, and shows the information contained in the second difference data table.

[0078] S406 . Obtain a target data value corresponding to the calibration data to be modified from the third difference data table according to the flash memory start address.

[0079] Exemplarily, after obtaining the flash memory start address of the calibration data to be modified, the target data value corresponding to the calibration data to be modified can be obtained from the third difference data table according to the flash memory start address. Table 3 uses the information in Table 2 as a reference to show the flash memory related information contained in the third difference data table.

[0081] Flash start address 1 Data value 1 Flash start address 2 Data value 2 …… …… Flash memory start address N Data value N

[0082] In the embodiment of the present invention, Figure 2 The step S203 may further include the following step S407:

[0083] S407. According to the flash memory start address, RAM start address and quantity, the target data value is copied from the flash memory to the RAM, so that the initial value corresponding to the calibration data to be modified in the basic calibration data is replaced with the target data value, and the target calibration data corresponding to the target vehicle is obtained.

[0084] Exemplarily, the target data value can be copied from the flash memory to the RAM according to the number of calibration data to be modified, so that the initial value corresponding to the calibration data to be modified in the basic calibration data is replaced by the target data value, and the target calibration data corresponding to the target vehicle is obtained. For example, referring to Table 1, Table 2 and Table 3, the number of calibration data to be modified is N, and the data values ​​of the N difference calibration data can be copied from the flash memory to the RAM in sequence according to the flash memory starting address and RAM starting address of the N difference calibration data, so as to obtain the target calibration data. Table 4 shows the relevant information of the RAM contained in the third difference data table with reference to the information in Table 2 and Table 3.
