  • Electric power steering system
    Patent number: 9346486
    Abstract: When a steering speed reaches a steering speed determination threshold, a steering speed gain is set to “0”. As a result, a final basic assist controlled variable becomes “0”, and application of an assist force to a steering system is stopped. Therefore, repetition of so-called reverse assist that is a cause of occurrence of an unintended steering behavior, such as self-excited vibration, is stopped. Accordingly, the steering behavior is improved.
    Type: Grant
    Filed: December 20, 2013
    Date of Patent: May 24, 2016
    Assignee: JTEKT CORPORATION
    Inventors: Hidenori Itamoto, Gempei Nakasone, Takashi Mitsuhara, Makoto Ikeno
