  • Steering angle sensing apparatus and method thereof
    Patent number: 8047066
    Abstract: A steering angle sensing apparatus and method are provided. The apparatus and method sense the steering angle of a steering shaft by using a rotated bit value difference corresponding to the rotated angles of magnets, which are respectively coupled on an axis of one of a plurality of sub gears, when the sub gears with respectively different gear ratios rotate with a shaft gear that rotates together with the steering shaft.
    Type: Grant
    Filed: October 21, 2010
    Date of Patent: November 1, 2011
    Assignee: LG Innotek Co., Ltd.
    Inventors: Kyong Ho Kang, Choon Wook Park, Sung Kyu Bae, Chang Hwan Lee
