During the MBS Tech Days 2021, Marc Lässing from Daimler Truck held a presentation titled "Optimization of NVH Launching Performance of a Heavy-Duty Truck Using Simpack as FMU in Interdisciplinary Co-Simulation".

Modern trucks today use mainly automated manual transmissions, including automated clutch control. Launching behavior primarily depends on electronic clutch control and various hardware parameters like clutch friction behavior or clutch friction pad stiffness. To optimize the launching behavior regarding NVH and the performance, a full vehicle model including ECUs for engine, clutch, and transmission control was created, using Simpack as FMU inside an in-house co-simulation tool. Hardware parameters and software versions were evaluated to improve the launching behavior.

Marc Lässing graduated in 2000 as a Diplom-Ingenieur of Automotive Engineering at the University of Applied Science in Esslingen.
From 2000–2002 Marc worked at the former DaimlerChrysler AG as a CAE engineer at the Research & Technology Center for Vehicle Dynamics, having his first contact with Simpack.

In 2002 Marc joined the Daimler Commercial Vehicles CAE center for NVH Powertrain analysis. Marc is responsible for full vehicle simulations focused on drivetrain-induced vibrations and SiL co-simulation using Simpack and the center-wide Simpack installation
