Research on Model-Based Testing of Lane Departure Warning System

This paper proposes a new test method on a model-based testing of lane departure warning system (LDWS), including model development, virtual integration and test management. Simulated models - like vehicle dynamics, vehicle maneuvers and virtual environment - are developed in TESIS DYNAWare. During virtual integration, the LDWS camera is located in the front of a computer monitor displaying virtual environment to capture pictures of lane marking. Vehicle dynamic model and maneuver model run on a NI real-time platform, which represents a virtual vehicle, and communicates with LDWS controller via CAN bus. Test management can be used in process monitoring, data collecting etc. The model-based method will make it easier to create various test scenarios, which can save time and costs by transferring complex test catalogues to the laboratory. The dangers presented in experiments in some critical scenarios can also be prevented. The repeatable model-based method makes it more convenient to locate the problems, which in return makes it easier to compare and assess systems of different companies objectively.
