Abstract: A system for controlling a steering system of a vehicle includes sensors configured to sense a plurality of values corresponding to operation of the steering system, and a controller configured to receive the sensed plurality of values, the sensed plurality of values including inductive angle signals and a magnetic angle signal, based on the inductive angle signals, obtain a relative angle of a steering shaft using a first Vernier algorithm, based on the relative angle obtained by the first Vernier algorithm and the magnetic angle signal, obtain an absolute angle of the steering shaft using a second Vernier algorithm, and control the steering system based on the absolute angle obtained using the second Vernier algorithm.

Abstract: A method for steering torque sensor stray magnetic field cancellation includes receiving, from at least one magnetic sensor disposed within a torque sensing region, a detected magnetic field corresponding to an angular displacement between an upper steering shaft and a lower steering shaft of an electronic power steering system. The method also includes generating a first torque signal based on the detected magnetic field and receiving, from at least one stray region sensor disposed outside of the torque sensing region, a detected stray magnetic field. The method also includes determining a torque signal error based on the detected stray magnetic field and generating a second torque signal based on the first torque signal and the torque signal error. The method also includes selectively controlling at least a portion of the electronic power steering system using the second torque signal.

Abstract: A magnetic support structure of a torque sensor assembly includes a central hub surrounding an upper shaft. Also included is a plurality of spoke segments extending radially outwardly from the central hub, each of the spoke segments comprising a pair of magnet supports. Further included is a plurality of magnets, each of the magnets disposed between adjacent magnet supports of the spoke segments.
