Abstract
A fault-handling system for a 2-phase motor. When an electric motor is used for power assist in a steering system in a vehicle, malfunctions can cause loss of assist, and detectable vibration. The invention utilizes a 2-phase motor in such an application, and implements alternate modes of operation when certain malfunctions occur, thereby maintaining the assist function in situations wherein the function would otherwise be lost or reduced.
