Automated HMI Testing Tool for Vehicle Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated testing tools for Human Machine Interface (HMI) applications are limited to testing features associated with the electronic device on which they are installed, and do not automate the process of testing HMI features across multiple applications, leading to high time and resource costs and variability in quality during manual regression testing.
Innovation Solution
An automated testing method and tool that identifies HMI-enabled vehicles and applications, integrates additional features, generates test data based on historical analysis, and executes test scripts to automate the testing of HMI applications, reducing manual labor and improving testing efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If automated testing tools are developed specifically for each application, then testing accuracy for that application is improved, but device complexity and testing scope are limited
Solution Approach 1:
The patent applies universality by developing a single automated testing tool that can test multiple HMI applications across different vehicles and electronic devices. The tool includes a universal interface that can identify and interact with various HMI applications without requiring application-specific custom tools, thereby reducing device complexity while maintaining testing accuracy through standardized testing protocols.
2Ease of operation
If manual testing is performed for HMI features, then flexibility in testing is improved, but time consumption and resource costs increase
Solution Approach 1:
The patent applies self-service by implementing automated testing that performs testing actions without requiring manual intervention. The automated tool independently identifies HMI applications, executes test cases, and analyzes results, thereby eliminating the time-consuming manual testing process while maintaining operational flexibility through programmable test scenarios that can be configured as needed.
3Adaptability or versatility
If manual regression testing is performed, then adaptability to new features is improved, but productivity decreases
Solution Approach 1:
The patent applies dynamics by implementing an automated testing system that can dynamically adapt to new HMI features and applications. The testing tool includes dynamic feature detection capabilities that automatically identify new features, generate appropriate test cases, and execute them without manual intervention, thereby maintaining adaptability while significantly improving productivity by eliminating manual regression testing.
