Multi-level vehicle dynamics modeling and export for ADAS prototyping in a 3D driving environment

Abstract

Advanced Driver Assistance Systems (ADAS) have evolved into comprehensive hardware and software driven components with exponentially growing complexity. Model-Based Design (MBD) is traditionally employed to accelerate the designvalidation-refinement cycle of such systems by reducing the occurrence of late nonconformities. However, MBD testing facilities can not provide a fully realistic verification environment compared to real test drives. Moreover, even road tests are limited, e.g., to reproduce driving situations and to test applications likely to cause property damage. Thus, this paper proposes to utilize driving simulators alongside MBD tools to achieve a fully virtual ADAS design and test environment. To put this idea in practice, the multi-level Vehicle Component Modeling and eXport (VCMX) framework is presented as the main contribution of this work. Finally, the combined tool support is evaluated by designing two ADAS from scratch so to highlight the advantages of utilizing VCMX especially in early prototyping stages of such applications.
