Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of Electronic Controller Units (ECUs) in vehicle systems is complex due to the use of specialized software building tools and methods that vary for each ECU, leading to inefficiencies in software assembly and deployment.
Innovation Solution
A uniform software assembly packaging method that integrates software assemblies using a testing script to produce a package containing binaries, metadata, and test results, ensuring compatibility and seamless installation across different ECUs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specialized software building tools and methods are used for each ECU, then software assembly can be tailored to specific ECU requirements, but the integration process becomes more complex and less efficient
Solution Approach 1:
The patent applies universality by creating a unified packaging system that handles all ECUs through a single standardized process. The packaging system uses universal templates, test scripts, and validation mechanisms that work across different ECU types, eliminating the need for separate specialized tools for each ECU while still maintaining ECU-specific customization capabilities through configurable parameters.
Solution Approach 2:
The patent utilizes parameter changes by allowing the packaging system to adapt to different ECUs through configurable parameters rather than requiring different tools. The system modifies packaging parameters (such as ECU identifier, software version, configuration files) to accommodate various ECU requirements while maintaining the same core packaging process, thus reducing integration complexity.
2Adaptability or versatility
If manual software assembly and deployment processes are used, then flexibility in handling unique ECU requirements is maintained, but productivity and deployment efficiency decrease
Solution Approach 1:
The packaging system implements self-service automation where the system automatically performs packaging, testing, and validation operations without requiring manual intervention. The automated test scripts execute independently, and the system self-validates software assemblies against defined criteria, significantly improving deployment efficiency while maintaining the ability to handle unique ECU requirements through automated configuration.
Solution Approach 2:
The patent applies preliminary action by performing validation and testing operations during the packaging process itself rather than after deployment. The system includes pre-defined test scripts that automatically validate software assemblies before they are deployed to ECUs, ensuring readiness in advance and eliminating the need for manual post-deployment checking, thus improving overall productivity.
3Productivity
If standardized packaging is implemented across all ECUs, then deployment automation and efficiency improve, but the ability to address ECU-specific requirements may be compromised
Solution Approach 1:
The packaging system segments the packaging process into distinct modular components that can be independently configured. The system divides the packaging into separate stages (assembly, testing, validation, packaging) with configurable parameters at each stage, allowing automation of the overall process while maintaining the ability to customize specific segments for different ECU requirements through modular configuration rather than custom tools.

AI summary
Uniform software assembly packaging is performed by testing an equipment software assembly according to at least one testing script included in the equipment software assembly to obtain test result information, producing an equipment package from the equipment software assembly, wherein the produced equipment package is executable to install and validate software on a target hardware element of a vehicle architecture specification included in the equipment software assembly. The produced equipment package includes a plurality of binaries, each binary corresponding to a program package among a plurality of program packages included in the equipment software assembly and a building script included in the equipment software assembly, metadata including debugging information, a description of the produced equipment package, and the test result information.
