Description

Background Art

[0002] In the field of motor vehicles, "calibration" refers to the process of optimizing software data after determining the engine, vehicle, control algorithm, and peripheral devices in order to obtain satisfactory vehicle performance, meet customer requirements, and meet national standards. The calibration of motor vehicles includes but is not limited to engine calibration, powertrain calibration, chassis calibration, battery management system calibration, etc. ECU is the electronic control unit of a motor vehicle, which stores the calibration information of the on-board electronic equipment, power system, etc. and uses this calibration information to perform control tasks.

[0003] Calibration information containing calibration values ​​or calibration quantities is widely used in the development of vehicle-mounted ECUs. Calibration quantities have a wide range of uses. Generally, the production origin number and production date can be stored in the ECU storage unit as calibration values ​​for tracking and backtracking. For functional safety modules, calibration values ​​can be stored in the ECU storage unit for key encryption and decryption algorithms. For strategy modules, motor gain values ​​can be stored in the ECU storage unit as calibration values ​​to implement motor modulation functions. Therefore, during the software release process, the correctness of the calibration quantity must be determined. At the same time, during bench debugging, since a large number of algorithms involve calibration quantities, it generally takes a lot of effort to extract and / or modify the calibration quantity.

[0004] In the prior art, calibration tools (such as INCA, CANape, etc.) and an operational test bench are generally required to extract calibration information from the storage unit of the ECU for modification or management. However, building a test bench and configuring calibration tools (such as INCA, CANape, etc.) and related work consume a lot of time and cost. In other words, this method has the disadvantages of high cost, slow configuration, and cumbersome settings. Moreover, the existing calibration tools also have restrictions on the modifiable parameters, so the flexibility of modifying the calibration amount is poor.

[0005] Therefore, the method for processing the calibration information of a motor vehicle, especially in terms of modifying the set value of a specific calibration quantity, still needs to be improved. The present invention aims to solve such problems in order to provide a faster and more convenient calibration solution. Summary of the invention

[0006] In order to solve the above-mentioned problems and defects, the present application proposes a method, a calibration system, a computer storage medium and an electronic device for processing calibration information of a motor vehicle.

[0007] According to one aspect of the present application, a method for processing calibration information of a motor vehicle is provided, wherein the motor vehicle is based on the AUTOSAR software architecture standard, and the method comprises:

[0008] -Get configuration standard files;

[0009] - Get the universal address allocation file;

[0010] - obtaining a binary file, the binary file containing calibration information of the motor vehicle;

[0011] - obtaining identity information of at least one relevant calibration quantity;

[0012] - Based on the acquired configuration standard file, universal address allocation file, binary file and identity information of the at least one relevant calibration quantity, extracting setting information of the at least one relevant calibration quantity from the binary file without using a calibration tool.

[0013] Here, through the above method, calibration information can be extracted from a binary file without using a calibration tool and a related test bench, and the binary file can be optionally modified. The time and cost of configuring calibration tools, building a bench, and related connection debugging work are avoided. At the same time, the restrictions on the amount of calibration that can be extracted or modified due to the calibration tool are avoided, thereby improving the flexibility of calibration information processing. Therefore, calibration information can be extracted from a binary file quickly, flexibly, and efficiently, and optionally modified. This can assist R&D engineers in automatically verifying the accuracy of the calibration information in the binary file, and can also assist engineers in quickly modifying the relevant calibration information in the binary file, thereby achieving the purpose of rapid debugging.

[0023] The exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the content of this application comprehensive and complete and to fully convey the concepts of the exemplary embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0024] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, elements, etc. can be adopted. In other cases, known structures, methods or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0025] This application takes a motor vehicle based on the AUTOSAR architecture as an example, and in particular takes a method for extracting and possibly modifying the setting value of its specific calibration quantity as an example, to introduce a method and a calibration system for processing the calibration information of a motor vehicle.

[0026] AUTOSAR (AUTomotive Open System ARchitecture) is a software architecture standard for electronic systems in motor vehicles. AUTOSAR provides an open software architecture standard for electronic systems in motor vehicles. It includes a series of specifications and standards covering various aspects of automotive electronic systems, such as software architecture, communication, diagnosis, safety, etc. Based on this open software architecture standard, the reproducibility, interoperability and scalability of electronic systems in motor vehicles are promoted.

[0027] With the widespread use of AUTOSAR architecture in the automotive field, the development of embedded software has become more convenient and safer, but the readability of configuration code has gradually weakened. In practice, it is found that there are situations where calibration information in storage units needs to be quickly parsed and / or modified in batches. However, it is actually difficult to quickly calculate and modify the storage unit information in the compiled file according to the configuration parameters in the configuration block. In the electronic system of motor vehicles based on the AUTOSAR architecture, calibration quantities, such as but not limited to, engine ignition timing, gear switching parameters, ESP control parameters, etc. are generally stored in the ECU, that is, in the ECU program binary file. The binary file is an ECU program compiled and generated by a compiler, and the binary file is flashed into the ECU as an ECU program in mass production. Such a binary file is, for example, a BIN file.

[0028] Refer to the following Figure 1 An embodiment of a method for processing calibration information of a motor vehicle according to the present application is introduced, by which binary files, especially ECU program binary files, can be processed without using calibration tools, thereby achieving simple and direct extraction and possible modification of the calibration information.

[0029] In the method according to the present invention, first, a configuration standard file is obtained in step S01. Here, the configuration standard file includes, for example, an ARXML file based on the AUTOSAR software architecture standard.

[0030] In step S02, a general address allocation file is obtained, and the general address allocation file includes, for example, a map file of a compiler (C compiler). In the general address allocation file, the location of the configuration block where the relevant calibration quantity is located in the FLASH is specified, that is, the absolute address of the configuration block is specified. Here, "configuration block" should be understood as a storage area in an ECU storage unit that is artificially defined.

[0031] In step S03, a binary file is obtained, and the binary file contains calibration information of the motor vehicle. That is, the binary file contains at least one calibration quantity and its setting information. The binary file should be understood as: a computer executable file flashed into the ECU, that is, an ECU program file compiled and generated by a compiler.

[0032] In step S04, identity information of at least one relevant calibration quantity is obtained. Here, the "relevant calibration quantity" is the calibration quantity concerned in the current operation or debugging, that is, the calibration quantity that needs to be verified, viewed or modified at present. All calibration quantities contained in the binary file can be specified as "relevant calibration quantities" or only a part of the calibration quantities contained in the binary file can be specified as "relevant calibration quantities" by input or setting.

[0033] Here, the identity information of the relevant calibration quantity manually inputted can be obtained by using an input device, or the identity information of the relevant calibration quantity can be obtained from other devices by using an interface. The identity information should be understood as information by which the calibration quantity can be identified in a binary file, which may include a parameter name of the relevant calibration quantity or a code name in a binary file, etc.

[0034] Then, in step S05, based on the obtained configuration standard file, universal address allocation file, binary file and identity information of the at least one relevant calibration quantity, the setting information of the at least one relevant calibration quantity is extracted from the binary file without using a calibration tool. Here, the setting information should be understood as the specific setting of the relevant calibration quantity, such as but not limited to a specific setting value or setting curve or setting function or lookup table, etc. For example, for the calibration quantity of the engine control of the motor vehicle, the setting information of the calibration quantity of the engine throttle opening may include a function dependent on the accelerator pedal, the transmission gear, the engine speed and / or the vehicle speed, etc.

[0035] Here, "calibration tool" should be understood as a software tool that manages or modifies calibration quantity by using interface interaction and test platform. Existing calibration tools include INCA, CANape, etc. The characteristics of these tools are that they need to be used together with the test platform and require a complex adaptation process.

[0036] The step S05 may include the following sub-steps:

[0037] - Parse the configuration standard file based on the identity information of the relevant calibration quantity to obtain the configuration parameters of the relevant calibration quantity. Here, the configuration parameters of the relevant calibration quantity may include: the configuration block where the relevant calibration quantity is located, the offset address of the relevant calibration quantity, the length of the relevant calibration quantity and / or the format of the relevant calibration quantity. The offset address of the relevant calibration quantity should be understood as the offset address of the relevant calibration quantity relative to the configuration block where it is located. The length of the relevant calibration quantity can be specified as a number of bytes, and the format of the relevant calibration quantity can be specified as uint32 or uint8, etc.

[0038] - Parse the universal address allocation file based on the configuration block where the relevant calibration quantity is located and the identity information of the relevant calibration quantity to obtain the absolute address of the configuration block where the relevant calibration quantity is located and the starting address of the binary file. Here, preferably, the universal address allocation file is parsed using a regular matching method.

[0039] - Based on the configuration parameters of the relevant calibration quantity, the absolute address of the configuration block where the relevant calibration quantity is located and the start address of the binary file, the location information of the relevant calibration quantity can include the address and length of the setting information of the relevant calibration quantity in the binary file.

[0040] - Extracting setting information of the relevant calibration quantity from the binary file based on the position information of the relevant calibration quantity.

[0041] In this embodiment, the method for processing the calibration information of a motor vehicle may further include an optional step S06. In this step, the update setting information of the relevant calibration quantity is obtained and based on the update setting information and the location information of the relevant calibration quantity, the original setting information of the calibration quantity is directly modified to the update setting information in the binary file. In this step, the modified binary file may also be flashed to the ECU. Of course, the method may also not include the step S06.

[0042] It should be understood that the order of the above method steps is only illustrative, and those skilled in the art can recognize various method solutions different from the above execution order based on their understanding of the prior art and common knowledge. For example, but not limited to, steps S01 to S04 can be performed in different orders and can be performed in parallel.

[0043] By using the above method, the time for extracting and / or modifying the calibration information is significantly reduced. At the same time, due to the scalability of the method, the correctness of the calibration in the storage unit can be automatically verified, reducing the probability of large-scale errors. At the same time, during the debugging process, if the calibration needs to be modified, the method can be used directly without relying on any software / hardware tools (only the relevant files need to be obtained), which significantly improves flexibility.

[0044] Figure 2 It is a schematic block diagram of a calibration system for a motor vehicle according to an embodiment of the present application. As shown in the figure, the calibration system for a motor vehicle includes a data acquisition unit 01 and a calibration information management unit 02, and the data acquisition unit 01 is configured to acquire a configuration standard file, a universal address allocation file, a binary file, and identity information of at least one relevant calibration quantity. Here, the binary file contains the calibration information of the motor vehicle, in particular a BIN file. The data acquisition unit can be a combination of multiple parallel data interfaces, or any type of interface for receiving or reading data.

[0045] The calibration information management unit 02 is configured to extract setting information of at least one relevant calibration quantity from the binary file without using a calibration tool based on the acquired configuration standard file, the universal address allocation file, the binary file and the identity information of the at least one relevant calibration quantity.

[0046] In this embodiment, the calibration information management unit 02 includes a configuration file parser 021, which is configured to parse the configuration standard file based on the identity information of the relevant calibration quantity, so as to obtain the configuration parameters of the relevant calibration quantity. The configuration parameters of the relevant calibration quantity may include: the configuration block where the relevant calibration quantity is located, the offset address of the relevant calibration quantity, the length of the relevant calibration quantity and / or the format of the relevant calibration quantity.

[0047] The calibration information management unit 02 further includes a regularization engine 022, which is configured to parse the general address allocation file based on the identity information of the relevant calibration quantity and the configuration block where the relevant calibration quantity is located, so as to obtain the absolute address of the configuration block where the relevant calibration quantity is located and the starting address of the binary file. Figure 2 As shown, the regular engine 022 obtains the configuration block where the relevant calibration quantity is located from the configuration file parser 021.

[0048] The calibration information management unit 02 further comprises a position calculation module 023, which is configured to obtain the position information of at least one relevant calibration quantity based on the configuration parameters of the calibration quantity, the absolute address of the configuration block where the calibration quantity is located and the start address of the binary file.

[0049] The calibration information management unit 02 may further include an optional binary file modification module 024, which is configured to directly modify the original setting information of the relevant calibration quantity into the updated setting information in the binary file based on the update setting information of the relevant calibration quantity and the position information of the relevant calibration quantity, and flash the modified binary file to the ECU. The setting update information of the relevant calibration quantity can be acquired by the data acquisition unit.
