Combined Man-in-the-Loop and Software-in-the-Loop Simulation

Abstract

The main targets in commercial vehicle development in the near future will be improving the energy effiency of the vehicles and improving vehicle safety. One of the measures to increase safety is the decision of the European Committee to make electronic stability systems compulsory for nearly all trucks and buses. To guarantee that the system performs well for a wide variety of trucks and buses, new simulation methods are being introduced into the development process. The system functionalities, which are developed by system suppliers, are implemented by Daimler Trucks as software-in-the-loop codes into vehicle dynamics simulation models. By using the multi-body simulation software’s real-time capabilities, it has become possible to investigate the interaction between the vehicle and the electronic stability system on the Daimler driving simulator.
