Innovations in Power Steering Increasing demands on energy effi- ciency, comfort and safety are driving the development of mechatronic systems in motor vehicles. These demands are especially relevant for steering systems. In this field electro- mechanical power steering is gaining in popularity, and the functionality of these systems is extendable via software and steadily increasing. The system under development must fulfill both individual haptic require- ments and specific safety-critical requirements. In order to meet these challenges, DMecS GmbH & Co. KG has worked together with the Cologne Labora- tory of Mechatronics (CLM) at the Cologne University of Applied Sci- ences to develop a feedback steering wheel (figure 1). This allows the front-loading of tests on prototy
