摘要： A fail-safe steering system for a vehicle, which prevents movable elements of a backup mechanism from being dragged by motions of an associated one of a steering input section and a steering output section under normal operating conditions of the system, is provided. The fail-safe steering system includes two selectively engageable clutch mechanisms operatively connectable between the steering input section and the backup mechanism and between the backup mechanism and the steering output section. The fail-safe steering system also includes a mechanism for keeping the backup mechanism in the neutral condition during backup mechanism being mechanically separated under normal operating conditions of the system.

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 vehicle steering system is provided with a primary steering system, a backup steering system and a control system that switches from the primary steering system to the backup steering system when a defect is determined in the primary steering system such as a defeat in a steering reaction force actuator. The vehicle steering system has a pair of clutches that mechanically disconnect the steering wheel from the steerable vehicle wheels in normal situations, and connect them when the steering reaction force actuator is determined to be defective. The control system has a steering malfunction detection section that detects a malfunction in the steering reaction force actuator, and a steering control limiting section that limits the control commands to the steering gear unit actuator from when the steering reaction force actuator is determined to be malfunctioning to when both the clutches are connected.

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： In a multiplex power steering device for a wheeled vehicle, there is provided a control unit which includes a feedback computing part. The feedback computing part comprises an operating force estimating section that, by analyzing an output from a controlled system of actuators of a steering mechanism, estimates an output of the actuators, a disturbance estimating section that, by comparing a control signal actually fed to the actuators and the estimated output of the actuators, estimates a disturbance applied to the controlled system from the exterior, and a disturbance compensating section that adjusts the control signal in a manner to remove the estimated disturbance therefrom. The control unit calculates the control signal on the assumption that the actuators constitute a single actuator.
