Description

A method, device and system for implementing distributed SWC link processing

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 30, 2023, with application number 202311428932.1, and invention name “A method, device and system for implementing distributed SWC link processing”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of vehicle controller software, and in particular to a method, device and system for implementing distributed SWC (Software Component, SWC) link processing in the AUTomotive Open System Architecture (AUTOSAR). Background Art

[0003] As vehicles become increasingly intelligent and connected, the development of automotive controller software is currently based on the AUTOSAR specification. According to the specification, software is divided into software components (SWCs) based on their functionality. SWCs can run on different electronic control units (ECUs). SWCs are defined using AUTOSAR description files (ARXML), and code is generated using AUTOSAR code generation tools. The core functionality of a SWC is to interact with other SWCs or underlying software components (BSWs) through input and output ports. Internal ports can also be used for internal communication.

[0004] Different SWCs can call each other; in this case, a link must be established between them to ensure proper communication. Specifically, in the automotive field, a link typically refers to the signal and interface connections in AUTOSAR, used to transfer data between different SWCs. Establishing this link requires defining signals, ports, and mapping them.

[0005] The AUTOSAR Builder tool, currently available in the market, provides a complete graphical user interface. It imports the ArXiv XML files of each module's SWC, parses the contents within the ArXiv, and ultimately abstracts them into a series of models. The linking process essentially binds the relationships between abstract models, converts the abstract models and their binding relationships into ArXiv data structures, and finally writes them back into the ArXiv, effectively linking the SWCs.

[0006] However, the existing solution of using commercial software tools to link SWCs has some shortcomings:

[0007] Low link efficiency. As automotive controller software becomes increasingly modular, features are iterated more frequently, and changes are made more frequently, every time a SWC is modified, it needs to be reassembled, leading to low link efficiency.

[0008] Poor link quality can easily lead to incorrect links. Because of the centralized "assembly" approach, all SWCs are visible and transparent, lacking link constraints. This can lead to incorrect links between SWCs, impacting overall software functionality and quality.

[0009] This causes unnecessary system overhead. Due to the real-time nature of linking, the parsing, structuring, and packaging of ARXML consume a certain amount of system overhead. Therefore, each link operation will cause an additional increase in system resources (primarily CPU and memory consumption). However, linking operations are often not one-time operations. Sometimes, SWCA and SWCB may link, and then cancel it; then, SWCA and SWCC may link instead. In this case, the system resources consumed by the previous link are wasted, resulting in unnecessary system overhead.

[0010] The above-mentioned deficiencies will seriously affect the development cycle of vehicle software.

[0011] Summary of the Invention

[0012] The technical problem to be solved by the present invention is to provide a method, device and system for implementing distributed SWC link processing, which can effectively improve the link efficiency and link quality between different SWCs, and reduce unnecessary system performance loss, thereby improving the development efficiency and flexibility of the entire vehicle software.

[0057] FIG6 is a schematic structural diagram of the link execution unit in FIG3 . DETAILED DESCRIPTION

[0058] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0059] As shown in FIG1 , a schematic diagram of the main process of an embodiment of a method for implementing distributed SWC link processing provided by the present invention is shown; together with the more detailed flowchart of FIG2 , in this embodiment, the method is applied to a vehicle including a distributed SWC server and a distributed SWC terminal.

[0060] It will be appreciated that in this embodiment, the distributed SWC server and distributed SWC terminals can typically be located in different ECUs within the vehicle. Modern vehicles contain numerous different ECUs, each responsible for controlling a specific function or subsystem. The distributed SWC server can be deployed on a dedicated ECU to coordinate and manage communications and connections within the vehicle, while the distributed SWC terminals can be deployed on other ECUs to interact with specific vehicle functions or sensors. This distributed architecture facilitates collaborative operation and communication between various components within the vehicle.

[0061] More specifically, the method provided by the present invention comprises at least the following steps:

[0062] Step S10, starting the SWC module service and registry service of the distributed SWC server;

[0063] More specifically, the step S10 further includes:

[0064] The SWC module service and the registry service of the distributed SWC server are started, and a service list of all current SWC module services and registry data corresponding to the registry service are loaded from an onboard memory (such as a non-volatile memory device).

[0065] It's understood that in automotive electronic systems, a SWC module refers to a software unit that controls a specific function or service. Each SWC module is responsible for performing a specific task or providing a function. For example, a car may have multiple SWC modules to control different functions, such as the engine control module, air conditioning control module, and brake control module. For example, the engine control module is responsible for monitoring and controlling engine operation. It receives sensor data (such as engine temperature and oil pressure) and adjusts the engine's operating state based on this data.

[0066] The registry is a data structure used to store configuration and parameter information. In automotive electronic systems, the registry is used to store various settings, parameters, and configuration information that may be loaded at system startup and accessed during runtime.

[0067] In step S10, the distributed server is started to load all SWC modules and corresponding registry data values ​​from a non-volatile memory (such as flash memory). This ensures that all necessary software components and configuration information are correctly loaded when the vehicle is started, so that all functions of the vehicle can operate normally.

[0068] Step S11: receiving a link registration request from a distributed SWC terminal, wherein the link registration request includes link information of the current registration request, including: a requesting SWC identifier (source_swc) and a target SWC identifier (target_swc); wherein the requesting SWC is the SWC requesting a link operation, and the target SWC is the SWC being linked;

[0069] Step S12, searching the service list of the started SWC module service to see if the target SWC identifier exists, determining whether the registration is successful, and notifying the requesting SWC of the registration result;

[0070] More specifically, in a specific example, step S12 further includes:

[0071] Searching whether the target SWC identifier exists in the service list of the started SWC module service; if the search result shows that the target SWC identifier exists, determining that the registration is successful, and storing the requesting SWC identifier and the target SWC identifier in the registry corresponding to the registry service; if the search result shows that the target SWC identifier does not exist, determining that the registration has failed;

[0072] The determined registration result is notified to the requesting SWC.

[0073] Step S13, storing the link information of this link registration request in the vehicle memory; specifically, storing the requester SWC identifier and the target SWC identifier in this link registration request in the vehicle memory, recording it as a link registration request, and notifying the distributed terminal that this link has been completed.

[0074] It is understandable that in the method provided by the present invention, the linking operation between SWCs needs to meet the following control conditions: the target SWC to be linked needs to be in the SWC module service list of the distributed server; at the same time, the target SWC to be linked and the requesting SWC that actively links need to exist in the registry of the distributed server.

[0075] Step S14 : executing the link operation corresponding to each link registration request according to the link information of each link registration request stored in the vehicle-mounted memory, and establishing a link relationship between each requesting SWC and the target SWC.

[0076] More specifically, in a specific example, step S14 further includes:

[0077] Determining whether a predetermined execution condition is met, wherein the predetermined execution condition is: link information of each link registration request stored in the vehicle memory reaches a predetermined quantity threshold, or the last link registration request is received for more than a predetermined time threshold;

[0078] When the predetermined execution condition is met, the link operations corresponding to all link registration requests are executed according to the link information of each link registration request stored in the vehicle memory, and the link relationship between each requesting SWC and the target SWC is established. The specific execution of the link operations corresponding to all link registration requests can be referred to and combined with the above description.

[0079] It is understood that, in the method of the present invention, before step S11, the following steps are further included:

[0080] Receive SWC information addition, modification or deletion requests pushed by distributed terminals, and perform corresponding addition, modification or deletion operations in the registry.

[0081] It is understood that the method provided by the present invention is different from the traditional centralized "assembly" SWC method, which requires obtaining the latest and most complete SWC information every time a link is made. Instead, it adopts a distributed technical solution that effectively integrates different terminal SWCs. Each time a terminal SWC is updated, it can submit it to the distributed SWC server. In this way, other terminals can obtain the current latest SWC, thereby improving the efficiency of the linking process.

[0082] At the same time, if a new SWC is added, modified, or deleted in a distributed terminal, it is submitted to the distributed SWC server through a local push method on the distributed terminal. The SWC module service enabled in the distributed SWC server stores the latest SWC information on a non-volatile storage device. These SWC changes are automatically "aggregated" to the distributed server, effectively avoiding the previous repetitive "assembly" method and greatly improving its efficiency.

[0083] In the method of the present invention, a registry mechanism is adopted so that the SWC can only "display" which specific SWCs to actively link to, thereby avoiding incorrect link objects and improving link quality;

[0084] In the method of the present invention, by adopting the "lazy" linking mode, when the SWC completes all the final links, a real linking operation is finally performed uniformly according to the data stored in the non-volatile storage device, thereby effectively reducing unnecessary system resource overhead.

[0085] FIG3 is a schematic diagram showing a structure of an embodiment of a device for linking distributed SWCs provided by the present invention. Combined with FIG4 to FIG6 , in this embodiment, the device 1 at least includes:
