Patent number: 11661106Abstract: A steering system includes a rotary shaft to which an operation member is coupled; a first actuator; a second actuator; a control unit; and a moving unit configured to move the operation member between a normal position and a storage area. The control unit is configured to switch between a manual drive mode and an autonomous drive mode. The control unit is configured to, when moving the operation member from the storage area to the normal position, start synchronous control when the operation member satisfies a predetermined condition before the operation member reaches the normal position, the synchronous control being control in which the control unit controls the first actuator to change a rotation angle of the rotary shaft to an angle corresponding to a steered angle of steered wheels driven by the second actuator.Type: GrantFiled: January 11, 2021Date of Patent: May 30, 2023Assignee: JTEKT CORPORATIONInventors: Takeshi Watanabe, Yasuyuki Nozawa

Patent number: 11472465Abstract: A steering device for steering a vehicle includes a movable member, a holding member, an impact absorbing member, a movement driving unit, and a controller. The controller is configured to perform first control and second control by which the movement driving unit is controlled. The first control is a control for moving the movable member along an axial direction of a shaft member within such a range that a front end of at least one of the shaft member and the movable member is located rearward of a space for movement in the front-rear direction of the vehicle. The second control is a control for moving the movable member along the axial direction within such a range that the front end portion is located inside the space for movement.Type: GrantFiled: April 21, 2020Date of Patent: October 18, 2022Assignee: JTEKT CORPORATIONInventors: Yasuyuki Nozawa, Norihiro Ochi, Ryoichi Tokioka, Takeshi Watanabe

Patent number: 11198464Abstract: A steering system includes an operation member; a first movement mechanism configured to move the operation member between a normal position and a storage area located forward of the normal position; a second movement mechanism configured to move the operation member so as to change a position of the operation member in an up-down direction of the vehicle; and a control unit configured to control the first and second movement mechanisms. The storage area is located inward of an opening of a vehicle member provided in front of a driver's seat in the vehicle. The control unit is configured to control, in a case where the operation member is retracted into the storage area, the first movement mechanism and the second movement mechanism to perform a forward movement of moving the operation member that has reached a vicinity of the vehicle member, along an outer shape of the vehicle member.Type: GrantFiled: July 15, 2020Date of Patent: December 14, 2021Assignee: JTEKT CORPORATIONInventors: Takeshi Watanabe, Yasuyuki Nozawa
