Combining traffic and vehicle simulation for enhanced evaluations of powertrain related ADAS for trucks

Advanced driver assistance systems (ADAS) may change both vehicle dynamics and driver behaviour. To study traffic-related impacts of a powertrain-related ADAS for trucks, a simulation-based approach was developed. The paper presents an approach to interconnecting a microscopic traffic simulation model and a vehicle simulation model including modelling of ADAS functionality. Verification tests demonstrate that the approach is practical and that high ADAS penetration rates can be run within reasonable simulation execution times. The verification tests also demonstrate that current truck dynamics modelling in the Aimsun and Vissim traffic simulation models does not capture all relevant aspects of truck driving behaviour and dynamics related to vertical grades.
