Abstract

A method to provide a selective torque assist to the primary motor in an electric vehicle/Hybrid vehicle is disclosed. The method comprises of embedding torque assist motors on the two output shafts of the primary motor differential. The torque assist motors can be turned ON to provide a short term torque boost to the primary motor differential particularly at zero or very low speed. The Torque assist motors may have multiple windings to provide different torque boost.
