Inductive and magnetic multiturn absolute steering angle sensor

A method for controlling a steering system of a vehicle, the method comprising:

• sensing, using one or more sensors, a plurality of values corresponding to operation of the steering system;
• receiving the sensed plurality of values, wherein the sensed plurality of values includes inductive angle signals and a magnetic angle signal;
• based on the inductive angle signals, obtaining 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, obtaining an absolute angle of the steering shaft using a second Vernier algorithm;
• and
• controlling the steering system based on the absolute angle obtained using the second Vernier algorithm.

A processor configured to execute instructions stored in memory, wherein executing the instructions causes the processor to control a steering system of a vehicle, the instructions comprising:

• sensing, using one or more sensors, a plurality of values corresponding to operation of the steering system;
• receiving the sensed plurality of values, wherein the sensed plurality of values includes inductive angle signals and a magnetic angle signal;
• based on the inductive angle signals, obtaining 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, obtaining an absolute angle of the steering shaft using a second Vernier algorithm;
• and
• controlling the steering system based on the absolute angle obtained using the second Vernier algorithm.
