Abstract:
Vehicles, systems, and methods for determining a distance travelled are provided. In an exemplary embodiment, a vehicle includes an electric motor with a motor rotor shaft. A motor resolver is positioned adjacent to the motor rotor shaft, where the motor resolver is configured to determine a motor position of the electric motor based on revolutions of the motor rotor shaft. A controller is in communication with the motor resolver, where the controller is configured to determine a distance travelled from a change in the electric motor position.
