Steer-by-wire assembly, method, and absolute position sensor thereof

Abstract

A steer-by-wire assembly, method and absolute position sensor for a vehicle, comprises a first motor with a stator and a rotor, a screw actuator configured to engage a threaded portion of a steering shaft and move the steering shaft longitudinally when the screw actuator rotates, and a rotor carrier sleeve coupled between the first rotor and the screw actuator, configured to rotate about the longitudinal axis of the steering shaft. The assembly also includes a first rotary position target arranged around the rotor carrier sleeve, wherein the position of the first rotary position target corresponds to a unique position of the steering shaft, and a first rotary position sensor configured to detect movement of the first rotary position target and send a sensor signal to a controller.
