摘要： A vehicle steering apparatus includes a steering input section having at least a steering wheel to which steering input is applied, and a steering output section having at least a steering rack shaft and operatively associated with left and right steered wheels for steering the steered wheels by steering-rack-shaft movement produced by a steering force determined based on the steering input and transmitted directly or indirectly to the steering rack shaft. The steering rack shaft is split into left and right movable rack shaft portions. Also provided is a steer angle converter enabling a differential rack stroke between left and right rack strokes of the left and right movable rack shaft portions. The steer angle converter is constructed by at least one of a variable-pitch dual rack arrangement and a dual taper-pulley arrangement of a cable back-up mechanism.

摘要： A steering apparatus for a steerable vehicle includes a steering unit, an operating unit, a backup unit, and a control unit. The backup unit selectively connects/disconnects the steering unit and the operating unit. The control unit is operable in two control modes including an SBW mode and a PS mode. In the SBW mode, the control unit separates the steering unit from the operating unit; controls a steer angle of the vehicle in accordance with a manual steering effort; and switches the control mode from the SBW mode to the PS mode when an SBW-to-PS mode switch condition is satisfied, the SBW-to-PS mode switch condition including a condition that the steer angle is larger than or equal to a first threshold angle. In the PS mode, the control unit connects the steering unit and the operating unit; controls an assist steering effort to boost the manual steering effort.

摘要： To reduce the length in the axis direction of a steering unit and consequently to provide a vehicle steering apparatus with superior vehicle mountability, a steering apparatus for a vehicle has a steering unit and a reaction generating unit, and a steered unit. The steering unit and the steered unit are mechanically separated. The apparatus includes a clutch that mechanically connects the steering unit and the steered unit, and a backup unit that is provided between the clutch and the steered unit and transmits the steering torque that is inputted from the steering unit, when the clutch is engaged, to the steered unit. A rotation conversion unit that outputs rotation in a rotation axis direction of the clutch that is different from the rotation axis direction of the steering unit is provided between the reaction generating unit and the clutch.
