Test Automation Tool for Electronic Control Unit’s Software Testing [ ]


With the technology scaling down, reduced device sizes have enabled us to deploy a wide range of electronic devices in a small area. The Electronic Control Unit (ECU) along with various sensors is an integral part of today’s vehicles. To satisfy various needs like safety, comfort, environment protection, etc., the control algorithm or engine software must be highly responsive and accurate. Manual testing of these algorithms requires longer testing time and may also include manual errors. Therefore, there is a need to develop test automation tool for testing engine software in order to verify all possible positive and negative effects before testing on actual vehicle. This tool will help us to test the modifications in engine software offline in closed loop system and predict results on vehicle. Proposed test automation tool uses NI TestStand as a software platform for test sequence development. To verify developed test automation tool NI VeriStand will be used as a real-time environment and LUIS bench as a hardware platform.
