Proper control of Electric Power Steering (EPS) systems requires both speed and direction information from the steering input shaft. This control will typically come from both high-resolution speed information and fairly coarse position information.

Many applications in different industries, such as in industrial automation and automotive sensors and actuators, require monitoring the angle of a rotating shaft either in an on-axis or off-axis arrangement. This application note is dedicated to a review of on-axis magnetic applications.

P0234: Electric power steering systems have become popular in automotive manufacturing, displacing their mechanical counterparts because they save space, weight, emissions, and reduce fit complexity.

P0225: As vehicle electrification has increased over the years in the automotive industry, standards such as SAE J3016TM have established levels of automation where automated driving elements have become increasingly adopted across broad classes of vehicles.

Engineers developing Electric Power Steering (EPS) systems must deliver instantaneous and precise motor control to support modern ADAS and steer-by-wire architectures. A critical architectural decision often overlooked early in the design process is the choice of current sensing methodology.
