Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0034] Next, the relevant technical terms in this application will be explained.

[0035] Taking the Adaptive AUTOSAR system (AUTOSAR Adaptive Platform System) as an example, this application describes the software standard architecture upon which the in-vehicle operating system relies. Adaptive AUTOSAR is a software architecture based on the AUTOSAR standard, supporting autonomous driving functions and internet connectivity, enabling vehicles to possess higher levels of intelligence and connectivity. It aims to provide more flexible, scalable, and adaptive solutions for automotive electronic systems. As a standardized middleware supporting high-performance ECUs of the next-generation electronic and electrical architecture, Adaptive AUTOSAR is designed and developed based on the principles of Service-Oriented Architecture (SOA). By providing a unified software architecture and interface standards, the Adaptive AUTOSAR system allows for the integration of hardware and software in vehicles, simplifying the development, integration, and maintenance of automotive electronic systems.

[0036] The Adaptive AUTOSAR system consists of a central computing platform (AP) and a regional controller. Service-oriented communication is possible between the AP and the regional controller, and communication between the AP and external devices is possible via Ethernet. For example... Figure 2 As shown, four regional computing units are connected via Ethernet with the central computing unit as the center, and the four regional computing units communicate with the external network through the central computing unit.

[0037] In automotive operating systems, vehicle ECU development refers to the process of developing both the software and hardware for the vehicle's Electronic Control Unit (ECU). The vehicle ECU is a core component of the vehicle's electronic system, responsible for managing and controlling various vehicle functions and systems, including engine control, transmission system, body control, and safety systems. The development process for a vehicle ECU includes requirements analysis, software design, programming, hardware design, and testing and verification. The aim is to ensure that the vehicle ECU meets the vehicle's performance, safety, and environmental requirements, while also comprehensively considering software and hardware compatibility, stability, reliability, and support for various communication protocols and standards. It is a crucial step in the development of vehicle electronic control systems.

[0038] Measurement and calibration are crucial steps in the entire process of vehicle ECU development, ranging from the calibration of individual component software parameters on the bench to the calibration of the vehicle under different time and season conditions.

[0039] With the development of intelligent and connected vehicles, on-chip computing software systems have become more complex, and the number of variables inside the ECU is enormous. During vehicle operation, key variables need to be observed and controlled in real time. In order for the system to operate well, the key variables on which the control algorithm depends need to be initially assigned values ​​and dynamically updated or corrected based on the effective actual values ​​or errors during operation in order to seek an optimal state value.

[0040] In automotive systems, the traditional method for parameter measurement and calibration is the CCP protocol based on CAN (Controller Area Network). This protocol is generally applicable to MCUs running CP systems (AUTOSAR classic platform systems). In the CAN network, the transmission of calibration data is achieved through variable access and calibration based on physical addresses. Usually, the calibration data is directly associated with its physical storage address.

[0041] However, in the Adaptive AUTOSAR system of the new generation of computing chips, multi-process and multi-tasking are supported. Different tasks can run in different processes, resources are isolated between processes, and each process has its own independent resources and virtual address space. Variable addresses are virtual addresses within the virtual address space. Therefore, the traditional CCP system is not suitable for the Adaptive AUTOSAR system of the new generation of computing chips.

[0042] In the Adaptive AUTOSAR system of the new generation of computing chips, the official standards and architecture still lack functional modules for measuring and calibrating internal variables of the ECU.

[0043] This application proposes an Ethernet-based method for measuring and calibrating on-board ECUs for the Adaptive AUTOSAR system. It introduces the XCP-ON-Ethernet protocol (XCP) for real-time measurement and calibration of internal ECU variables.

[0044] The basic XCP on IP communication model under the Ethernet-based Measurement and Calibration Protocol (XCP Over Internet Protocol) is a process of request and response, exchanging data and commands. The Master (such as XCP Master) is the requester, and the Slave (such as XCP Slave) is the responder. XCP protocol data uses TCP / UDP as the transport layer protocol, and is treated as TCP / UDP payload data. It has advantages such as independence from the physical transport layer, large communication capacity, strong portability, flexible deployment, and strong scalability.

[0045] According to one aspect of the embodiments of this application, a method for determining the calibration value of a driving variable is provided. This method for determining the calibration value of a driving variable is widely used in intelligent vehicle and other smart IoT application scenarios. Optionally, in this embodiment, the above-described method for determining the calibration value of a driving variable can be applied to, for example... Figure 1 The hardware environment shown consists of vehicle terminal 102 and server 104. Figure 1 As shown, server 104 is connected to vehicle terminal 102 via a network and can be used to provide services (such as application services) to the terminal or clients installed on the terminal. A database can be set up on the server or independently of the server to provide data storage services for server 104. Cloud computing and / or edge computing services can be configured on the server or independently of the server to provide data processing services for server 104.

[0046] The aforementioned networks may include, but are not limited to, at least one of the following: wired network, wireless network. The aforementioned wired network may include, but is not limited to, at least one of the following: wide area network, metropolitan area network, local area network. The aforementioned wireless network may include, but is not limited to, at least one of the following: Wi-Fi (Wireless Fidelity), Bluetooth.

[0047] This embodiment provides a method for determining the calibration values ​​of driving variables, applied to the aforementioned vehicle terminal. The vehicle terminal supports the Adaptive AUTOSAR system, and the XCP-ON-Ethernet protocol is introduced into the Adaptive AUTOSAR system. For example... Figure 3 As shown, this process is implemented by an external device with an XCP graphical interface (the aforementioned external device), where the external device corresponds to the XCP Master within the XCP-ON-Ethernet protocol. Figure 3 This is a flowchart (I) of a method for determining the calibration value of driving variables according to an embodiment of this application. The flowchart includes the following steps:

[0048] Step S302: In response to a trigger operation from the interactive interface, a measurement task is generated for the current onboard data generated by the target vehicle during driving.

[0049] It is understandable that the interactive interface provides users with interactive commands, allowing them to interact with the interface through touch, click, tap, voice control, etc., and the interactive interface then generates trigger operations.

[0050] The current vehicle data can include, for example, vehicle speed, vehicle direction, vehicle position, environmental perception data, vehicle driving status, obstacle detection data, traffic signal recognition, and inter-vehicle communication data.

[0051] Step S304: Send the task instructions required when the measurement task is executed to the central computing platform so that the central computing platform can parse the task instructions and obtain the driving variable calibration values ​​corresponding to the current vehicle data;

[0052] Optionally, it should be noted that the above-mentioned driving variable calibration values, such as constant string identifiers, are stored in a predefined and configured editable file. For example, the Per module provided by Adaptive AUTOSAR can be used to read this editable file into the corresponding virtual storage space in memory, and then read and write access to the editable file can be completed in the virtual storage space.

[0053] Among them, the above-mentioned task instructions include, but are not limited to, the XCP protocol standard basic command for measurement tasks that implement the basic protocol functions of the XCP protocol, the XCP protocol Calibration command for measurement tasks that implement the data calibration function of the XCP protocol, and the XCP protocol synchronization data request for measurement tasks that implement the data synchronization function of the XCP protocol.

[0054] Step S306: Update the current value of the driving variable of the target vehicle to the calibration value of the driving variable.

[0055] Through the above steps, an external device based on the XCP protocol responds to a trigger operation from an interactive interface to generate a measurement task for the current onboard data generated by the target vehicle during its operation. The task instructions required for the execution of the measurement task are sent to the central computing platform, which then parses the task instructions to obtain the calibration values ​​of the driving variables corresponding to the current onboard data. The current values ​​of the driving variables of the target vehicle are updated to the calibration values ​​of the driving variables. This solves the technical problem in related technologies of how to determine the calibration values ​​of driving variables during vehicle operation to improve vehicle operation accuracy, thereby improving vehicle operation accuracy.

[0056] In an exemplary embodiment, the implementation process of sending the task instructions required for the execution of the measurement task to the central computing platform in step S304 above specifically includes: step S11, determining the target transmission interface from the data transmission interface provided by the Ethernet network where the target vehicle is located; step S12, generating a TCP server based on the XCP protocol based on the target transmission interface and the TCP communication protocol, and generating a UDP server based on the XCP protocol based on the target transmission interface and the UDP communication protocol, wherein the TCP server and the external device have a TCP communication channel based on the TCP communication protocol, and the UDP server and the external device have a UDP communication channel based on the UDP communication protocol; step S13, sending the task instructions required for the execution of the measurement task to the central computing platform through the TCP communication channel, and / or, sending the task instructions required for the execution of the measurement task to the central computing platform through the UDP communication channel.

[0057] In this embodiment, the target transmission interface is first determined from the data transmission interface provided by the Ethernet network where the target vehicle is located. Then, a TCP server based on the XCP protocol is generated according to the target transmission interface and the TCP communication protocol, and a UDP server based on the XCP protocol is generated according to the target transmission interface and the UDP communication protocol. A TCP communication channel based on the TCP communication protocol can be established between the TCP server and the external device, and a UDP communication channel based on the UDP communication protocol can be established between the UDP server and the external device. In this way, communication between the external device and the central computing platform can be realized through two different communication channels, thereby improving communication efficiency and accuracy.

[0058] In an exemplary embodiment, before sending the task instructions required for the execution of the measurement task to the central computing platform, the method further includes: step S21, determining the task priority of each measurement task for the plurality of measurement tasks, and determining the execution order of the plurality of measurement tasks according to the task priority of each measurement task, wherein the task priority of each measurement task is determined according to the data storage address corresponding to the task instruction of each measurement task.

[0059] Understandably, a smaller data storage address corresponds to a higher priority. By allocating data storage addresses to different task instructions and then determining the task priority of measurement tasks based on these addresses, the execution order can be determined according to task priority. This eliminates the need to analyze and determine the execution order of each measurement task individually, thus improving the execution efficiency of measurement tasks. Furthermore, each measurement task has an independent process and can utilize its own independent process resources, further enhancing the execution speed of measurement tasks.

[0060] In an exemplary embodiment, step S306 further includes the following execution steps: Step S31, when it is determined that the measurement task is used to implement the basic protocol functions of the XCP protocol, a first task instruction required when the measurement task is executed is generated, wherein the basic protocol functions include at least an initialization protocol function and an asynchronous calibration value acquisition function; S32, the first task instruction is sent to the central computing platform, so that the central computing platform generates an initialization protocol channel between the central computing platform and the external device based on the task instruction, and parses the task instruction to obtain the driving variable calibration value corresponding to the current vehicle data; S33, the driving variable calibration value is obtained from the central computing platform based on the initialization protocol channel.

[0061] In this embodiment, a first task instruction can be sent to the central computing platform. Based on the first task instruction, an initialization protocol channel is generated between the central computing platform and the external device, thereby realizing the initialization protocol function. Furthermore, through the initialization protocol channel, a communication channel is established between the external device and the central computing platform, and the driving variable calibration values ​​calculated by the central computing platform can be obtained through this communication channel.

[0062] In an exemplary embodiment, further, after performing the above step S21, the method includes: step S22, where, if it is determined that the measurement task is used to implement the data calibration function of the XCP protocol, a second task instruction required when the measurement task is executed is generated, wherein the data calibration function represents writing data to the central computing platform; step S23, the second task instruction is sent to the central computing platform so that the central computing platform parses the task instruction, obtains the driving variable calibration value, and writes the driving variable calibration value corresponding to the current vehicle data into the central computing platform.

[0063] In this embodiment, a second task instruction can be sent to a central computing platform. After parsing the task instruction based on the second task instruction, the driving variable calibration value is obtained. Then, according to the second task instruction, the driving variable calibration value corresponding to the current vehicle data is written into the central computing platform. In this way, the central computing platform can write the driving variable calibration value into the application connected to it, and update the driving variable calibration value in real time within the application, thereby displaying the latest results to the user and improving the user experience.

[0064] In an exemplary embodiment, further, after performing the above step S21, the method may include: step S41, where, if it is determined that the measurement task is used to implement the data synchronization function of the XCP protocol, a third task instruction required when the measurement task is executed is generated, wherein the data synchronization function is used to synchronize the driving variable calibration value from the central computing platform to the external device; step S42, the third task instruction is sent to the central computing platform so that the central computing platform parses the task instruction, obtains the driving variable calibration value corresponding to the current vehicle data, and sends the driving variable calibration value according to a preset period.

[0065] This embodiment uses a third task instruction to synchronize the driving variable calibration values ​​from the central computing platform to the external device. Furthermore, when the third task instruction is sent to the central computing platform, the central computing platform can parse the task instruction to obtain the driving variable calibration values ​​corresponding to the current vehicle data, and send the driving variable calibration values ​​according to a preset period. On the one hand, data synchronization improves data security, and on the other hand, sending the driving variable calibration values ​​multiple times in a period reduces the probability of data loss.

[0066] To better understand the process of determining the above-mentioned driving variable calibration values, the implementation flow of the above-mentioned driving variable calibration values ​​determination method will be described below in conjunction with optional embodiments, but this is not intended to limit the technical solution of the embodiments of this application.

[0067] This embodiment provides a method for determining the calibration value of driving variables. Figure 4 This is a flowchart (II) of the method for determining the calibration value of driving variables according to an embodiment of this application, as shown below. Figure 4 As shown, the specific steps are as follows:

[0068] Step S402: Parse the task instructions from the external device based on the XCP protocol to obtain the parsing result, wherein the parsing result includes at least the task type of the task instructions;

[0069] Step S404: Call the proxy interface corresponding to the task type, and send the task instruction to the application of the central computing platform through the proxy interface to control the application to execute the task instruction and obtain the driving variable calibration value of the target vehicle.

[0070] Through the above steps, a central computing platform based on the XCP protocol parses task instructions from external devices based on the XCP protocol to obtain parsing results. The parsing results include at least the task type of the task instruction. A proxy interface corresponding to the task type is invoked, and the task instruction is sent to the application program of the central computing platform through the proxy interface to control the application program to execute the task instruction and obtain the driving variable calibration value of the target vehicle. This solves the technical problem in related technologies of how to determine the driving variable calibration value of a vehicle during driving to improve the accuracy of vehicle operation, thereby improving the accuracy of vehicle operation.

[0071] It is understandable that the driving variable calibration values ​​of the target vehicle and the driving variable calibration values ​​corresponding to the current on-board data are essentially the same. They are just different descriptions for different subjects. The driving variable calibration values ​​of the target vehicle correspond to the central computing platform based on the XCP protocol, that is, the driving variable calibration values ​​corresponding to the current on-board data correspond to the external devices of the XCP protocol.

[0072] In an exemplary embodiment, the process of parsing the task instruction from the external device based on the XCP protocol in step S402 to obtain the parsing result further includes the following steps: Step S51, decrypting the task instruction using a pre-agreed decryption format between the external device and the central computing platform to obtain message information; Step S52, performing format verification on the message information, and determining the message information as the parsing result if it is determined that the message information passes the format verification.

[0073] In this embodiment, the task instruction can be decrypted using a pre-agreed decryption format between the external device and the central computing platform to obtain message information. Then, the message information that passes the format verification is determined as the parsing result, thereby improving the confidentiality and security of the data.

[0074] In an exemplary embodiment, step S404 further includes: step S61, when it is determined that the task instruction is a basic instruction based on the XCP protocol, calling the first proxy interface corresponding to the task type; step S62, sending the task instruction to the application of the central computing platform through the first proxy interface, so as to control the application to establish an initialization protocol channel between the central computing platform and the external device based on the task instruction, and to execute the task instruction to obtain the driving variable calibration value.

[0075] In this embodiment, the first proxy interface corresponding to the task type can be called through the basic instructions of the XCP protocol to send the task instructions to the application of the central computing platform. Then, the application establishes an initialization protocol channel between the central computing platform and the external device based on the task instructions, and executes the task instructions to obtain the driving variable calibration value. In this way, the central computing platform can realize interaction with the external device through the initialization protocol channel, such as sending the driving variable calibration value to the external device.

[0076] In an exemplary embodiment, step S404, in addition to steps S61-S62, may further include: step S71, in determining that the task instruction is a calibration instruction based on the XCP protocol, calling the second proxy interface corresponding to the task type; step S72, sending the task instruction to the application of the central computing platform through the second proxy interface to control the application to execute the task instruction, obtain the driving variable calibration value, and write the driving variable calibration value into the application software connected to the central computing platform.

[0077] In this embodiment, the calibration command based on the XCP protocol can call the second proxy interface corresponding to the task type and send the task command to the application of the central computing platform. The application then executes the task command to obtain the driving variable calibration value. In this way, the central computing platform can write the driving variable calibration value into the application software connected to the central computing platform and update the driving variable calibration value in real time within the application, thereby improving the accuracy of the data displayed to the user in real time.

[0078] In an exemplary embodiment, in addition to steps S61-S62 and S71-S72, step S404 further includes: step S81, in determining that the task instruction is a synchronization instruction based on the XCP protocol, calling a third proxy interface corresponding to the task type; step S82, sending the task instruction to the application of the central computing platform through the third proxy interface, so as to control the application to send the obtained driving variable calibration values ​​to the external device according to the start instruction of the task instruction at a preset period, and to stop sending the driving variable calibration values ​​according to the end instruction of the task instruction.

[0079] In this embodiment, a synchronization command based on the XCP protocol calls a third proxy interface corresponding to the task type. The task command is then sent to the application program on the central computing platform through the third proxy interface. The application program sends the acquired driving variable calibration values ​​to the external device according to a preset cycle based on the start command of the task command, and stops sending the driving variable calibration values ​​according to the end command of the task command. This not only allows for multiple transmissions of driving variable calibration values, reducing the probability of data loss, but also improves the control efficiency of sending driving variable calibration values ​​by controlling the cessation of transmission of driving variable calibration values ​​after successful transmission according to the end command of the task command.

[0080] In one embodiment, such as Figure 5 As shown, the measurement and calibration software architecture based on the Adaptive AUTOSAR architecture standard includes the XCP protocol stack platform module (platform layer) and the XCP APP application software (application layer). The XCP Stack (slave), as the implementation component of the measurement and calibration protocol, belongs to the application layer protocol of TCP / UDP. It can represent the configured XCP calibration quantification configuration file as a set of calibration quantifications to be read or written during subsequent measurement and calibration, and is used as the basis for determining the validity of a certain calibration quantification. It can call the Per interface to read the memory space corresponding to the XCP calibration quantification configuration file. Under the measurement and calibration software architecture, when using sub-functional services, cross-process calls are required through the "ara::com" interface. In short, this application, based on the POSIX standard interface, uses the XCP Daemon Slave program as the basic XCP functional module of the AP under the XCP Protocol, establishing communication with the XCP Master to provide XCP measurement and calibration functional services. The "ara::com" interface can represent an application programming interface (API) or an interface used for communication and data exchange between different software modules of communication protocols such as the XCP Protocol.

[0081] Among them, the calibration variables (such as constant string identifiers) in the XCP calibration configuration file mentioned above can be predefined and editable files. By using the Per module provided by Adaptive AUTOSAR to read and write this editable file, the read calibration values ​​can also be persistently stored, realizing the dynamic configuration of the calibration quantity and improving the dynamic flexibility of measurement and calibration.

[0082] Among them, the calibration variable can be understood as the calibration value of the driving variable mentioned above.

[0083] It should be noted that the XCP protocol includes several sub-protocols, each with its own business functions. These business functions are completed through independent processes. For example, the CM module provided by Adaptive AUTOSAR can be used to enable cross-process communication between the XCPDeamon process and the XCP App.

[0084] Furthermore, for details on the communication and interaction process, please refer to [link / reference]. Figure 6 A timing diagram. For example... Figure 6 As shown, the basic mode of measurement and calibration is request-response, i.e., Master-Slave. The Master, for example, is an external device with an XCP graphical interface. This external device can be used to observe calibration values ​​and trigger calibration; it is the initiator of the command. The Slave corresponds to the XCP Stack / Damon, serving as the central computing unit and receiving instructions from the external device. Then, the XCP Application, in conjunction with the SlaveDamon, completes the specific tasks of measurement and calibration.

[0085] Specifically, the implementation process is as follows:

[0086] Step 1. Based on the socket interface of the Ethernet protocol stack of POSIX OS, build TCP / UDP communication services and create XCP TCP server and XCP UDP server respectively.

[0087] Step 2. Generate XCP standard basic commands (corresponding to measurement tasks that implement the basic protocol functions of the XCP protocol) according to the Ethernet-based XCP Protocol specification. Send the XCP standard basic commands to XCPDeamon, which parses the Command Transmission Object (CTO). When the CTO task is completed, construct the response command for the CTO. The XCP standard basic commands (i.e., the first task instructions mentioned above) are used to complete basic protocol functions such as connection initialization for measurement and calibration, and their range is 0xF1–0xFF.

[0088] Specific correspondence Figure 6 In:

[0089] In step S601, the Master (i.e., XCP Tool) constructs the FF command CTO (i.e., XCP-CTO / CONNECT(FF)) and sends it to establish a Master-Slave connection (TCP or UDP).

[0090] In step S602, the Slave (i.e., XCP Daemon) receives the FF command, performs initialization, and returns RES FF (i.e., XCP-CTO / RES(FF)) to the Master, indicating that the connection is established.

[0091] In step S603, the Master constructs an asynchronous measurement F4 message CTO (i.e., XCP-CTO / SHORT UPLOAD(F4)) and sends it to the Slave n.

[0092] In step S604, the Slave decapsulates the message and sends the decapsulated data (i.e., read datal()) to the F4 App application, i.e., the XCP Application, and reads the calibrated value in the F4 App application.

[0093] Step S605: Send the return value (i.e., read datal()) to the Slave so that the Slave can forward the return value to the Master.

[0094] In step S606, the Slave returns a RES FF response (i.e., XCP-CTO / RES(FF)) to the Master.

[0095] Step 3. Generate an XCP protocol Calibration command based on the Ethernet-based XCP Protocol specification (corresponding to the measurement task used to implement the data calibration function of the XCP protocol, i.e., the second task instruction), and send the XCP protocol Calibration command to the XCP Daemon. The XCP Daemon parses the Calibration Command Transmission Object (CTO). When the task of writing the calibration value is completed, it constructs a response command for the Calibration Command Transmission Object (CTO).

[0096] The XCP protocol calibration command is used to write data to the XCP Slave, and its range is 0xEC-0xFO.

[0097] It's understandable that the Calibration command in the XCP protocol is used to send calibration data or parameters to the ECU. This command allows for the adjustment, calibration, and optimization of parameters within the ECU. These parameters can include curves, mappings, calibration coefficients, etc., used to adjust functions such as engine control, transmission control, fuel system, and emission control. Through the Calibration command, engineers can adjust the vehicle's performance and characteristics to meet different performance and environmental requirements.

[0098] Specifically, for example, the Master constructs FO command data CTO and sends it. After receiving the FO command data, the Slave parses it and further completes the writing of the calibrated value in the FO App application, and returns RES FF to the Master.

[0099] Step 4. Generate an XCP protocol synchronization data request (corresponding to the measurement task used to implement the data synchronization function of the XCP protocol, i.e., the third task instruction) according to the Ethernet-based XCP Protocol specification. Send the XCP protocol synchronization data request to the XCP Daemon, which parses the Command Transmission Object (CTO). After the command task is completed, construct the Data Transmission Object (DTO) and complete the periodic transmission of DAQ command data of the Data Transmission Object (DTO), that is, periodically return DAQ data from the XCP Slave to the XCP Master.

[0100] The XCP protocol synchronization data request is used to synchronize XCP Slave data to XCP Master, and its range is 0xE3-0xC7.

[0101] Specific correspondence Figure 6 In:

[0102] In step S607, the Master constructs a DD synchronization measurement start command CTO (i.e., XCP-CTO / START STOP SYNC(DD)) and sends the message.

[0103] In step S608, after receiving this DD CTO, the Slave returns a RES FF response (i.e., XCP-CTO / RES(FF)).

[0104] In step S609, while responding, the Slave triggers the periodic sending of DTO / DAQ (i.e., XCP-DTO / DAQ()) messages to the Master according to the instruction.

[0105] Steps S610 to S611 can refer to steps S604-S605 above.

[0106] In step S612, the Master constructs a DD synchronization measurement end command CTO and sends the message.

[0107] In step S613, after receiving this DD CTO, the Slave ends the cycle by sending a DAQ message and returning a RES FF response.

[0108] Step 5. Each sub-function of the XCP protocol requires the cooperation of the application layer XCP App to implement. When it is necessary to read or write data, the corresponding XCP application programming interface (API) should be designed, such as the read or write data interface.

[0109] After designing the client / server communication code framework for CM communication, interface types such as Method / Event / Field can be flexibly designed. Then, the Adaptive AutoSar CM module interface can be used to implement communication between the XCP App process and the XCP StackDeamon process. This means that by providing XCP application programming interface header files and a dynamic library encapsulating the cross-process communication framework, it can be called by external XCP measurement and calibration application scenarios.

[0110] In this embodiment, after receiving and parsing the F4 / FO / DD instruction CTO through the Slave, it calls the corresponding CMProxy interface to send the request to the XCP Application where the corresponding F4 / FO / DD function service CM Skeleton is located, and completes the reading and writing of the calibrated value within the XCP Application.

[0111] Through the above steps, the XCP-ON-Ethernet protocol (XCP) is introduced into the Adaptive AUTOSAR system for real-time measurement and calibration of ECU internal variables, thereby improving the rationality of ECU calibration values.
