Owing to ever more stringent regulations and customers’ expectations, auto manufacturers have beenconsidering numerous technology options to improve vehicle fuel economy. One of these is transmission technology, whichhas been shown to be one of the most cost-effective technologies. Over the past few years, transmissions have significantlyevolved and have impacted both performance and fuel efficiency. As one of the advanced tranmissions, the dual clutchtransmission (DCT) is the first automatic transmission to provide better efficiency than manual transmissions. DCTs providereduced shift shocks and better driver comfort in addition to higher top speeds and torques. In this paper, a model and shiftingcontroller for the DCT are developed in the vehicle systems context using Autonomie, a model-based vehicle simulation tool. Finally, the Autonomie DCT model and control strategy are validated using vehicle test data from Argonne’s AdvancedPowertrain Research Facility. KCI Citation Count: 10
