构建和呈现汽车电子测试数据，以减少决策过程中的工作量
Structuring and presenting data for testing of automotive electronics to reduce effort during decision making
摘要：
汽车工程被认为是软件和机械工程的结合，因为汽车中基于软件的组件数量不断增加。由于汽车变得比以前更复杂，以确保鲁棒性，因此汽车电子产品的测试大量进行，产生大量的测试相关数据。本研究通过在领先的汽车公司之一沃尔沃汽车进行探索性案例研究，探讨了来自汽车电子测试的非结构化和分散的测试相关数据如何在测试工件的测试和分析过程中产生决策问题。根据探索性研究的结果，设计了一个原型，以改善汽车电子测试分析和诊断的数据和信息结构和表示。原型的结果表明，提供更好的数据和信息结构显着提高了效率，并减少了测试人员进行测试分析和诊断时的工作量。测试人员表明，由于更好的信息结构，演示，正确性和可访问性，与测试相关的任务的任务负荷减少。因此，这些改进有助于测试人员有效地做出关于失败测试的根本原因分析的决定。这项研究的结果可以帮助汽车公司系统地调查和改进汽车电子测试过程中管理和构建测试相关数据。关键词：测试，汽车电子，电子控制单元，ECU，非结构化数据。
英文摘要：
Automotive engineering is recognized as a combination of software and mechanical engineering due to the ever-increasing number of software-based components in vehicles. Since vehicles have become more sophisticated than before to ensure robustness, testing of automotive electronics is performed in high volume, producing immense test-related data. This study investigates how unstructured and decentralized test-related data from testing of automotive electronics creates issues in decision making during the testing and analysis process of test artifacts by performing an exploratory case-study at one of the leading automotive companies, Volvo Cars. From the findings of the exploratory study, a prototype was designed to improve the data and information structure and presentation for test analysis and diagnostics for automotive electronics. The prototype's results showed that providing better data and information structure significantly increases the efficiency and reduces the workload for testers when conducting test analysis and diagnostics. Testers showed a decrease in task load for tasks related to testing due to better information structure, presentation, correctness and accessibility. Hence, the improvements aided the testers to arrive at decisions regarding root cause analysis of failed tests efficiently. The findings of this study can assist automotive companies in systematically investigating and improving the testing process of automotive electronics in regards to managing and structuring test-related data. Keywords: Testing, Automotive Electronics, Electronic Control Unit, ECU, Unstructured Data.
