Abstract
A motor in an electric vehicle can be controlled by receiving a torque command value, calculating a first flux value corresponding to a determinable efficiency of the electric vehicle at the torque command value, calculating a first torque-producing current value as a function of the torque command value and of the first flux value, and using the first flux value and the first torque-producing current value to control the motor to propel the electric vehicle.
