This paper focuses on systematical evaluation of Advanced Driver Assistance Systems and Automated Driving Functions. To overcome the curse of dimensionality we propose to use a test case catalogue, which is proven to have a good coverage of critical traffic situation. Secondly, a method for assessment of safety performance is introduced. It is based on evaluating the performance limit of automated vehicle in a given test case and relating it to its overall exposure rate in real world traffic situations. Through a case study, the parametrization and generation of test scenarios and evaluation for an ADAS(ACC) system is presented.
