摘要： In a vehicle steering apparatus, a steering actuator is controlled so that the steering angle varies in accordance with the operation of an operating member. A transmission mechanism connects an operating side rotating member that is mechanically connected to the operating member and a vehicle wheel side rotating member that is mechanically connected to the vehicle wheels so that the mutual transmission of rotation is possible. Furthermore, the rotational transmission ratio between the operating side rotating member and the vehicle wheel side rotating member can be varied.

摘要： A control section (10) of a vehicle steering system has a steer-by-wire mode, a power steering mode, and a transition mode. In the steer-by-wire mode, a steering actuator (19) is controlled for steering and a reaction force actuator (11) is controlled for reaction force. In the power steering mode, steering assistance control is performed with either of the steering actuator (19) and the reaction force actuator (11) caused to function as an assistance unit. In the transition mode, in a transition period from either of the steer-by-wire mode and the power steering mode to the other, the reaction force actuator (11) is controlled for reaction force.

摘要： In a normal state, a reaction force actuator (20) applies an operation reaction force to an steering member (2) through a planetary gear mechanism (6). When failure occurs in a steering actuator (12), the reaction force actuator (20) is turned off, and a plunger (13) locks the rotation of one element (18) which is connected to the reaction force actuator (20), in the planetary gear mechanism (6). In turn, a manual steering mode is set up in which a rotation of the steering member (2) is transmitted to a pinion gear (14) at a transmission ratio of the carrier (16) holding planetary gears (17) and a sun gear (15).

摘要： The steering device is constructed by supporting a center portion of a rectangle-plate-shaped operation plate at one end of a supporting shaft projected from the front face of a dashboard so as to freely swing in right and left directions. A steering apparatus for a vehicle having the steering device detects the swing direction and the swing angle of the operation plate with a steering angle sensor provided at a support portion and moves a steering mechanism in the detected direction in accordance with the detected angle so as to steer the vehicle. With this structure, a load in steering can be decreased and tiredness in driving can be reduced. Furthermore, such a steering apparatus can realize a steering device which physically handicapped drivers can operate easily.

摘要： A vehicle steering apparatus in which a mechanical coupling between a steering member and steered wheels is uncoupled, includes a steering actuator for driving a steered mechanism and a control unit for drive-controlling the steering actuator. The control unit reduces steering-stiffness using a PID control portion for drive-controlling the steering actuator according to a deviation between a target steered angle and a steered-angle detected by the steered angle sensor. A gain setting portion sets gains of the PID control portion to be relatively low when a predetermined condition is satisfied.
