Abstract: Since 1995, GIF – Gesellschaft fur Industrieforschung mbH has been involved in the development of the cone ring transmission (KRG), which is a new traction-based continuously variable transmission (CVT). The KRG is suitable for small to medium class vehicle applications and is characterised by high efficiency, high dynamics and low costs. In this paper, we present the functional description of the KRG as well as the development of the control system for the ratio adjustment. Using model-based techniques, a robust control system is developed that ensures a high dynamic response of the ratio adjustment. Additionally to control quality, comfort is an important factor for ensuring the acceptance of the KRG. Using a vehicle model, the driving behaviour of the vehicle equipped with KRG can be predicted and optimised before the vehicle application. The developed control algorithms and strategies are validated on a vehicle equipped with KRG using a prototype transmission control unit.
