Patent number: 8068954Abstract: There is provided a steering apparatus to ease an uncomfortable feeling given to an operator when a steering wheel is connected to a steering mechanism, on a fail. The apparatus includes a unit that varies an angular ratio of a steering angle of front wheels with respect to an operational angle of a steering wheel. The apparatus also includes a connection unit such as a electromagnetic clutch for connecting the steering wheel to the steering mechanism in order to fix the angular ratio, on a fail such as a failure of a steering motor. The apparatus also includes a rotational body which relatively rotates with respect to the steering wheel by an angular deviation upon this connection. Accordingly, since a real neutral position of the steering mechanism coincides with a neutral position recognized by a pattern on the rotational body being seen, it eases the uncomfortable feeling onto the operator.Type: GrantFiled: January 24, 2008Date of Patent: November 29, 2011Assignee: JTEKT CorporationInventors: Kenji Higashi, Shiro Nakano, Masami Naka

Patent number: 8066094Abstract: A steering shaft is composed of an upper shaft, a lower shaft, an input shaft, and an output shaft. The upper shaft, the lower shaft, and the input shaft can rotate together, and the input shaft and the output shaft are relatively rotatably coupled to each other via a torsion bar. The rotational position of a rotor coupled to the output shaft is calculated based on the detected rotational position of the lower shaft and a steering torque detected based on the amount of relative rotational displacement of the input shaft and the output shaft. Thus, it is not necessary to include a rotor rotational position detecting unit for detecting the rotational position of the rotor within the electric motor, which reduces the size of the electric motor.Type: GrantFiled: April 30, 2008Date of Patent: November 29, 2011Assignee: JTEKT CorporationInventors: Kazuya Yoshioka, Yasuyuki Yoshii, Kenji Higashi, Shimon Jimbo, Masami Naka, Shiro Nakano
