The goal of reducing fuel consumption and CO2-Emission is leading to turbo-charged combustion engines that deliver high torque at low speeds (down speeding). To meet NVH requirements damper technologies such as DMF (Dual Mass Flywheel) are established, leading to reduced space for the clutch system. Specific measures need to be considered if switching over from SMF (Single Mass Flywheel) to DMF [8]. Doing so has an impact on thermal behavior of the clutch system, for example due to reduced and different distribution of thermal masses and heat transfer to the surroundings. Taking these trends into account, clutch systems within vehicle powertrains are facing challenges to meet requirements e.g. clutch life, cost targets and space limitation. The clutch development process must also ensure delivery of a clutch system that meets requirements taking boundary conditions such as load cycles and driver behavior into account.

Manual transmissions play a dominant role in India with a market share of more than 90%. Any technology that improves their fuel consumption and their comfort for end users is highly welcome if it is affordable regarding “value for money”. Schaeffler offers a technology to meet these challenges with the concept of Electronic Clutch Management (ECM). By implementing an intelligent mechatronic clutch actuator with specific, integrated sensors directly inside the actuator, this development prepares the ground for a new era that says farewell to the clutch pedal and achieves the target of using a 2-pedal system.
