Abstract:
An electric vehicle, an electric drive system and method of operating the electric vehicle. The electric drive system provides a torque to a wheel of the electric vehicle. The processor is configured to obtain a value of the torque at which the electric drive system of the vehicle is operating, determine an optimal speed for the vehicle for the torque based on an efficiency model of the electric drive system, wherein the optimal speed corresponds to an optimal drive efficiency for the electric drive system, and operate the vehicle at the optimal speed.
