This paper analyses the potential of dual clutch transmissions for MD and HD commercial vehicles in India. It compares vehicle performance, i.e. duration of a given transport cycle, and fuel consumption during this transport cycle for a 49 to. long haulage truck under typically given driving conditions in India. Additionally a performance comparison between 6 speed and 8 speed transmissions on long haul trucks in India is shown. The performance of different transmission types (MT, AMT and DCT) as well as 6 respectively 8 speed transmissions for each transmissions type are compared and discussed. The fuel efficiency as well as the cycle time of each individual transmission have been analyzed by powertrain system simulations. Furthermore the design of a modular transmission family concept for commercial vehicles (truck & bus) is presented. It combines both, a manual transmission as well as a powershift capable double clutch transmission within the same transmission family.

Due to more stringent emission standards as well as customer requirements on performance improvement, model-based controls in diesel engines are becoming more and more common and necessary. In fact, as diesel engines becoming increasingly complicated with additional hardware components such as electonic throttle, EGR, VVT, VGT, as well as aftertreatment devices, the dynamics of the systems with more freedom of multiple actuators become much more sophisticated. With such complexity in the diesel engine systems, the traditional simple PI control, single-input single-output type of controls will not be good enough to address the multivariable interactions among subsystems, instead the advanced model-based, multi-input multi-output and coordinated supervisory controls almost become the only effective ways to improve system performance and achieve emission standards.
