MODEL-BASED DEVELOPMENT AND SIMULATIVE VERIFICATION OF LOGICAL VEHICLE FUNCTIONS USING EXECUTABLE UN/ECE REGULATIONS

摘要

On the way towards autonomous driving, a steadily increasing number of Advanced Driver Assistance Systems leads to a tremendous test effort to approve their safe operation. However, route-based real-world tests cannot cover this effort sufficiently which is why virtual testing has become part of the vehicle development and approval process as well. Since regulations such as those of the United Nations Economic Commission for Europe, are mandatory for vehicle approval there is a need to integrate their prescribed test scenarios into virtual test environments. In this paper, we present a novel approach to transform these textually available scenarios into executable state machines. It is complemented by a holistic simulation-based verification where model-based vehicle functions are stimulated by sensor data of the virtual vehicle under test to achieve meaningful and more realistic results. We prototyped a tool-chain to execute approval-related test scenarios on the example of an Advanced Emergency Braking System.
