Abstract
Official abstract text for this publication.
Disclosed herein are a steering torque and steering angle measurement apparatus, the present invention including a stator fixed to an output shaft, a magnet disposed at the inner part of the stator and being fixed to an input shaft, a torque sensor measuring a steering torque by sensing a magnetic field produced between the stator and the magnet, and a steering angle signal generation part measuring the steering angle by outputting an ON signal ordinary times and outputting an OFF signal at each preset rotation duration of the output shaft when the output shaft rotates, thereby reducing a component number, simplifying a manufacturing process and saving a cost price.
