Abstract
An electric vehicle includes a plurality of electric drive units coupled to one or more axles of the electric vehicle. The drive units have an associated power loss map that is approximated by a plurality of second-order polynomials. Torque is apportioned between the electric drive units to minimize total power losses based on coefficients of the second-order polynomials for each of the electric drive units and a driver torque demand.
