Description

Technical Field

[0001] This invention belongs to the field of automotive software development technology, and in particular relates to a method for rapidly generating ARXML files based on PREEvision. Background Technology

[0002] Preevision is a model-based electronic and electrical architecture development tool that includes multiple layers such as requirements analysis, logic layer design, software layer design, hardware layer design, communication layer design, wiring harnesses, and topology. These layers are interconnected and mapped to each other. Preevision enables rapid generation of ARXML files. The main workflow involves first modeling using Preevision, then exporting the required version of the ARXML file using Preevision's export function. The modeling process primarily involves the software, hardware, and communication layers. The software layer mainly represents the SWC modules of the AUTS application software layer and their connections. The hardware layer is described in the form of a topology diagram, mainly showing the connections between the entire vehicle system or individual subsystem ECUs. Then, the SWC modules of the software layer and the ECUs of the hardware layer are associated through mapping, deploying the software components into the hardware ECUs. Then, the signal routing function can generate Signal, PDU, System Signal and Ethernet Communication Cluster. These elements are all located in the communication layer. After signal routing, detailed communication design needs to be completed in the communication layer, including renaming and setting parameters of Signal, PDU and Transmission, data serialization and parameter configuration of Ethernet layer protocols, etc.

[0003] With the development of the "new four modernizations" (electrification, connectivity, intelligence, and sharing) and Tesla's disruptive software update approach, new demands are being placed on automobiles in this new era: vehicle functions can be continuously iterated and updated after SOP (Start of Production), primarily through software updates, requiring more intelligent vehicle functions and interconnectivity with cloud services. To address these functional needs, more and more OEMs are adopting SOA (Service-Oriented Architecture) architecture. As vehicle intelligence develops, vehicle functions are becoming increasingly richer, and the number of services is increasing dramatically. This has led to a significant increase in the workload of Prevision modeling, resulting in a severe shortage of existing modeling personnel in the market, with varying skill levels among engineers, and a particular scarcity of experienced modelers. Furthermore, while modeling steps share many commonalities, most modeling engineers still rely on manual, repetitive processing. This is not only repetitive and complex but also prone to errors, causing generated files to be unrecognizable in downstream tools. Moreover, the sheer volume of services and data makes troubleshooting extremely difficult. Summary of the Invention

[0004] The purpose of this invention is to provide a method for rapidly generating ARXML files based on PREEvision, aiming to solve the problems mentioned in the background art.

[0005] The present invention is implemented as follows: One embodiment provides a method for rapid generation of ARXML files based on Preevision, comprising the following steps:

[0006] Step 1: Based on the secondary development function of PREEvision, use the JAVA language to develop Metrics that can automatically perform modeling in PREEvision software according to the commonalities of the modeling process, and then perform quick modeling based on the developed Metrics.

[0007] Step 2: Perform error checking and data recognition on the specific Excel spreadsheet, and serialize the data in the Excel into code-recognizable data, which will be used as input for subsequent automatic modeling of metrics;

[0008] Step 3: Based on the serialized data, generate the model hierarchy required for the modeling process under the specific Product Line. Then, create the Service and ServiceInterface defined in the table under the corresponding hierarchical structure, and create and assign data types. Finally, generate SWC Type and Port Type based on the created Service and Service Interface and associate the corresponding data types.

[0009] Step 4: Deploy services under a specific Product Line based on the serialized data. Instantiate and generate an SWC based on the pre-created SWC Type and Port Type. Map the SWC to the hardware layer ECU based on the serialized data. Create the VLAN, Socket Address and Socket Connection components required for Ethernet transmission and establish the association between the components.

[0010] Step 5: Based on the serialized data, complete the communication design under the specific Product Line. Rename the Signal, PDU, and Transmission components generated by the signal routing and set their parameters. Create the serialization components required for signal transmission. Generate the Header ID, Event Handler, Consumer EventGroup, and So Ad Routing Group required for Ethernet transmission and set their parameters.

[0011] Step 6: Based on the serialized data, create the communication components required for the TCP protocol-bound interface under the specific Product Line, including Socket Address, Socket Connection, and Socket Routing Group, and set their parameters;

[0012] Step 7: Based on the serialized data, correct and integrate the Service Discovery component created by SOA & EthernetExplorer under the specific Product Line;

[0013] Step 8: Based on the serialized data, create End To End Transformer and End To End Transformation Properties for the interfaces that need E2E protection under the specific Product Line, set the relevant parameters, and associate them with Signal.

[0014] Step 9: Based on the serialized data, filter out the interfaces bound to the UDP protocol under a specific Product Line, obtain the signals transmitted on the interface, identify signals with a payload length greater than 1400 bytes to create the SOMEIP-TP component, and set its attributes.

[0015] Step 10: After modeling with Metrics in PREEvision, you can use PREEvision's built-in ARXML export function to export the required version of the file.

[0016] A further technical solution involves manually creating the network topology at the hardware layer in step 3. This includes assigning Bus Types to Bus Systems and Bus Connector Types to Bus Connectors, and then assigning the created Bus Systems to the Ethernet Cluster to complete the topology design.

[0017] In a further technical solution, in step 4, the software layer ports are connected and signal routing is completed simultaneously through PREEvision's SOA & Ethernet Explorer.

[0018] A further technical solution involves creating the necessary components for Service Discovery using PREEvision's SOA & EthernetExplorer in step 6.

[0019] Further technical solutions include the following Metrics modules: CheckAndParseExcel, ServiceDefinition, HWAndComDefinition, ReNameAndOtherSetting, TCP, SDDefinition, E2E, and SOMEIP-TP.

[0020] In a further technical solution, the CheckAndParseExcel module is used to execute step 2, the ServiceDefinition module is used to execute step 3, the HWAndComDefinition module is used to execute step 4, the ReNameAndOtherSetting module is used to execute step 5, the TCP module is used to execute step 6, the SDDefinition module is used to execute step 7, the E2E module is used to execute step 8, and the SOMEIP-TP module is used to execute step 9.

[0021] The present invention provides a method for rapidly generating ARXML files based on PREEvision, the advantages of which are as follows:

[0022] (1) By providing Metrics based on secondary development of PREEvision software for modeling, the amount of repetitive work is reduced and the error frequency is lowered;

[0023] (2) Effectively shorten the R&D cycle and improve the development quality of electronic and electrical architecture. Attached Figure Description
