Abstract

A method for controlling a vehicle driveline includes connecting an electric motor to each of respective vehicle wheels, determining from driver input a magnitude of demanded wheel torque, determining speed of each wheel, using demanded wheel torque and the respective wheel speed to determine from a power loss map a current power loss for each motor, and transmitting power from the motor having the lowest current power loss to the respective vehicle wheel.
