Abstract

This paper describes a method used at Schaeffler to analyze integrated hybrid transmission architectures with one electric motor. Both the properties of their modes and aspects of mode transitions become clear using special visualization techniques. The method was implemented in MATLAB, and several transmission examples will be discussed. This leads to design aspects and requirements concerning the overall transmission layout and the components. Examples of beneficial components from Schaeffler are discussed. Small shifting elements allow more space for the electric motor. Clutches, brakes and CVT subsystems that are the right size for hybrid transmissions provide the required comfort. Low-friction bearings and on-demand actuators contribute to increased range of electric driving.
