Abstract

On the way to full automation the number of Advanced Driver Assistance Systems (ADAS) and the system’s Operational Design Domain (ODD) increase. This challenges today’s prevalent requirement-based testing paradigm in the automotive industry, as for each requirement at least one test is derived. While virtual testing offers scalability for large-scale testing, hardware integration-testing has to be performed under real-time constraints. A significant part of the verification on the target hardware is performed on Hardware-in-the-Loop (HiL) test systems. With the limited number of available HiL systems and their execution being bound to real-time constraints, test time becomes a precious resource. In this work we demonstrate a novel test strategy, that unites today’s requirement-based test process with new concepts for more efficient HiL testing. Maintaining traceability throughout the development process is the main goal. The tests are split into stimuli and evaluation, where only the stimuli are executed on the HiL. This enables parallel assessment of multiple functionalities in one test execution. The concept has been implemented in a productive HiL environment at a German car manufacturer and the evaluation shows benefits in test coverage, as well as reduced test runtime. Moreover, it enables scenario based testing of Highly Automated Driving.
