print3 December 2012 Seminar
Simulation-based Development of Transmission
Controls –
from Road to Rig to PC, HiL, SiL
This parallel to the introductory day newly established seminar is addressing experienced project managers and transmission experts. It shows how development tasks can be transferred from road to test rig, HiL or a pure virtual, PC-based environment via simulation. Costs and achievable benefits are compared using examples. The lecturers have many years of practical experience and expertise in the use of simulation for the development of transmission systems.
