Software Test Automation of Power Window Functionality

In the automotive industries, there is a constant development in control strategy with the use of electronic hardware and software for advanced functionality. Software test automation plays a crucial role in ensuring the quality and reliability of power window functionality in automotive systems. This paper aims to automate power window testing by prioritizing crucial functionalities like obstacle detection, thermal and voltage protection, and precise position tracking. The power window is a mechatronic application and its operation is controlled through software algorithm. To establish the experimental setup for this research, essential components such as the power window Electronic Control Unit (ECU), an external DC power supply, PCB layout design and software tools like the vector CANoe tool and Communication Access Programming Language (CAPL) browser were utilized. The automated testing methodology proposed in this paper helps to reduce the damaging of ECU and human injuries while testing. At present, the testing process is performed manually, requiring six weeks to complete 400 scenario checks. However, by automating this testing, the time frame can be significantly reduced to just two weeks. A comprehensive report is generated that includes detailed information such as the start time, end time, and recorded values.
