Engine and Gearbox Modeling and Simulation for Improving the Shifting Behavior of Powertrains with Manual or Automated Transmission 2006-01-1641

Automated gear shifting, which combines gearbox designs resembling those of manual gearboxes with control mechanisms interacting not just with the gearboxes but also with clutches or the engine, becomes increasingly popular in powertrain design, because it combines the efficiency of the manual gearbox layout with the comfort of automatic shifting. Typical examples are dual-clutch transmission systems for high-performance passenger cars or automated gearboxes in heavy duty vehicles. This paper addresses typical simulation and comfort optimization challenges in this field and illustrates modeling solutions as well as applications where this technology was applied in order to increase shifting comfort.
