Abstract
A computing device implemented method includes receiving one or more signals that represent an angular speed of a permanent magnet electric motor of a hybrid electric vehicle, the one or more signals being provided by an angular sensor connected to the electric motor, receiving a signal representing a voltage from the electric motor, the voltage being a direct axis voltage component of a three-phase motor model, 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, storing the correction factor, and determining a binary indication of a status of error angle, and repeating the steps until the binary indication is positive.
