Abstract

This paper proposes a novel electric differential concept for electric vehicles with distributed motors as a substituion of the mechanical differential gear. Motion models and options for the design of the powertrain are reviewed. Existing concepts of electric differential implementations are presented and structured into two main categories. Based on this, a new powertrain and electric differential concept is developed and presented. With this concept, the mechanical differential gear can be effectively replaced and synchronisation problems as existing with other electric differential solutions can be considerably reduced.
