摘要： A VGRS device checks whether assist control of an EPS device for assisting steering operation of a steering wheel is being stopped. If the assist control of the EPS device is being stopped, a speed increase ratio is determined so that the rotation angle of the output shaft is less than the rotation angle of the input shaft. A VGRS motor is controlled and driven based on a determined speed increase ratio. Thus, steering operation of the steering wheel can be controlled appropriately so that the steering operation of the steering wheel can be continued with relatively small torque. It is less likely that a driver will erroneously feel that the steering wheel is locked.

摘要： In a steering control apparatus, a worm gear is configured to have a lead angle for a self-lock operation, by which a worm wheel is allowed to rotate by rotation of a worm but the worm is not allowed to rotate by rotation of the worm wheel. Thus, a lock mechanism need not be provided separately from a gear mechanism and the apparatus is reduced in entire size. A VGRS control part checks whether the worm gear has a self-lock failure, which disables the self-lock operation. If the worm gear has the self-lock failure, idling suppression processing is performed to suppress idling of a steering wheel. Thus, even when the self-lock failure arises, the steering wheel is suppressed from idling.

摘要： A vehicular steering control apparatus has a steering direction control device and a reaction force application device. The steering direction control device controls a steering angle of steered wheels by controlling a steering direction control motor based on a steering wheel angle. The reaction force application unit is provided more closer to a steering wheel than the steering direction control device is and has a differential reduction unit and a reaction force application motor. The differential reduction unit transfers rotation of an input shaft to an output shaft. The reaction force application motor drives the differential reduction unit. The steering wheel and the steered wheels are normally linked mechanically, so that no fail-safe device is needed.

摘要： A steering control apparatus has a variable gear ratio device and a power steering device. If abnormality arises in the VGRS device, an EPS motor is controlled based on a steering wheel angle and a speed increase ratio. Thus, vehicle wheels are controlled appropriately when abnormality arises in the VGRS device. Steered angle of the vehicle wheels relative to the steering wheel angle is not changed between before and after occurrence of abnormality in the VGRS device. As a result, movement of a vehicle does not deviate from the steering wheel angle and feeling of discomfort in steering a vehicle can be reduced.

摘要： In a steering control system, an ECU calculates a basic transfer ratio in accordance with a steering angle detected by a steering angle sensor or a corrected transfer ratio by correcting the calculated basic transfer ratio in accordance with the position of a rack. The corrected transfer ratio decreases when the rack moves from a predetermined first position close to one end of a movable range, to the one end or from a predetermined second position close to the other end of the movable range, to the other end. The ECU determines either the basic transfer ratio or the corrected transfer ratio as the transfer ratio in accordance with the position of the rack. The ECU controls an actuator for a variable gear ratio system in accordance with the transfer ratio.

摘要： A steering control apparatus acquires vibration torque, which is generated by vibration of a gear mechanism when a steering wheel is operated at a steering angle. By setting the acquired vibration torque as a torque difference, an EPS motor current command value is corrected based on the torque difference thereby to calculate a corrected EPS motor current command value. Rattling and vibration caused in the gear mechanism are suppressed from being transferred to the steering wheel through an input shaft so that a driver is released from uncomfortable feeling.
