Abstract

Systems, computer readable media storing instructions, and computing device-implemented methods include receiving one or more signals that represent an angular speed of a permanent magnet electric motor of a hybrid electric vehicle, receiving a signal representing a voltage from the electric motor, determining if the angular speed is within a predetermined threshold, calculating an error angle representing a correction factor for an alignment of the electric motor based on a ratio of the voltage and the angular speed, determining if the error angle indicates that the motor is installed in a correct or an incorrect orientation, and adding an orientation correction factor to the error angle.
