Abstract: A steering system includes: a variable mechanism that reversibly changes a configuration of an operating member between a configuration for automated driving and a configuration for manual driving, the configuration including at least one of a position, an orientation, and a shape; a variable drive source; a receiver that receives an operation of a driver; and a controller that controls the variable drive source to cause the variable mechanism to return the configuration of the operating member to the configuration for manual driving, when the receiver receives the operation of the driver in a period when the configuration of the operating member is being changed.

Abstract: 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.

Abstract: A steering device that holds a steering member in such a manner that the steering member is movable between an advanced position where a driver can steer the steering member and a retracted position located closer to the front of a vehicle. The steering device includes: a fixed member attached to a vehicle body; a movable member to which a steering shaft holding the steering member is rotatably attached; and an upper guide mechanism and a lower guide mechanism that linearly guide the movable member with respect to the fixed member. An end on the advancing side of the upper guide mechanism is located further toward the advancing side than an end on the advancing side of the lower guide mechanism in an advancing and retracting direction of the movable member.

Abstract: 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.

Abstract: 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.

Abstract: A steering system includes an operation member; a first movement mechanism configured to move the operation member between a normal position at which the operation member is operated by a driver, and a storage area located forward of the normal position; and a control unit configured to control the first movement mechanism. The storage area is located inward of an opening of a vehicle member located 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 to move the operation member forward at a first speed, and to move the operation member forward at a second speed that is lower than the first speed when a distance between the operation member and the vehicle member becomes equal to or less than a predetermined distance.

Abstract: A steering device includes a movable body that rotatably supports a shaft member to which a steering member is attached, and first and second rail mechanisms that guide movement of the movable body in a front-rear direction. The first rail mechanism has a first rolling element row that is disposed between a first raceway face of a first fixed rail and a second raceway face of a first moving rail. The second rail mechanism has a second rolling element row that is between a third raceway face of a second fixed rail and a fourth raceway face of a second moving rail. A contact angle of each of a plurality of first rolling elements with respect to the first and second raceway faces, and the contact angle of each of a plurality of second rolling elements with respect to the third and fourth raceway faces are different from each other.

Abstract: A steering device includes: a first moving unit that moves in an axial direction along with a shaft member to which an operating member is connected; a second moving unit; a holding unit; a first screw mechanism; a second screw mechanism; a driving unit; and a transmission mechanism that transmits driving force of the driving unit to the first screw mechanism and the second screw mechanism. One of the first screw mechanism and the second screw mechanism is provided so as to operate in a forward direction when the operating member moves between a retraction region and an operation region, and reverse efficiency of that one screw mechanism is set such that when the operating member is subjected to an external force directed toward the retraction region, that one screw mechanism does not operate in a reverse direction.
