Powertrain Efficiency Through Friction Reduction

Friction reduction is one of many approaches for making powertrains more energy efficient. The aim is to minimise drivetrain losses through specific and strategic measures applied to individual components, while taking into account the impact on the overall system. For this purpose, interdisciplinary basic research topics were defined. Within the framework of the Low Friction Powertrain research cluster, a simulation model for an entire vehicle powertrain was developed at RWTH Aachen University and TU München for the virtual representation of relevant energy flow rates within a thermal management system, including a detailed description of a thermal gearbox model, for the purpose of evaluating measures to reduce powertrain friction.
