The paper presents a new 7-speed dual-clutch transmission (DCT) for transverse applications and a torque capacity of 200 Nm with an option for 300 Nm engine torque. Advantageously the system is designed for supplier parts of dual-clutch system, gear and clutch actuation, differential as well as bearings, synchronizers and additional standardized parts. The actuation could be also realized by an already developed hydraulic module which can be used and produced locally with supplier parts of valves, sensors and so on. Furthermore, the gear set is a state-of-the-art system which can be supplied by manual transmission manufacturer. Beside the cost focus. the DCT has a favorable gear set in terms of robustness and compactness. The design with a total length of 350 mm is realized through a common gear on the main shaft for each gear pair on the countershafts and multiple use of gears in the first speed.

Currently known hybrid systems are technically complex, cost-intensive and referring to this for many end-customers not available. Under this boundaries IAV has developed a cost-optimal concept of an efficient and modular powertrain platform for electric and hybrid vehicles. The system is based on one unity gear-set for up to three speeds, which enables seamless shifting with only one friction based clutch. With this platform powertrains can be realized by using a maximum number of carry over parts (COP) for electric vehicles as well as for hybrids. The derivable hybrid powertrains of the platform system are designed for 48V electric motors (EM) which enables the maximum cost potential in combination with the realized gear set and transmission technology. The real simple powertrain platform concept is furthermore scalable for different vehicle segments optionally with or without a hybrid option.
