Abstract
A method for detecting an absolute rotational position of an electromechanical device or the at least one component thereof comprising determining a first absolute position of the electromechanical device or the at least one component thereof based on a commutation index signal, obtaining a Z-index signal, and determining a second absolute position of the electromechanical device or the at least one component thereof based on the Z-index signal. The method initially determines a coarse rotational position of the electromechanical device such as a rotor or steering wheel based on the commutation index signal. When a device's position is first initialized by a commutation index signal before the Z-index pulse is detected, the device's position is re-initialized upon detection of the Z-Index pulse to provide a more accurate absolute device rotational position.
