摘要： A control device includes control circuits of a plurality of systems. When a transition condition is established, the control circuits of the systems make transition of a driving mode from a first driving mode to a second driving mode, and when a return condition is established in a state in which the driving mode has transitioned to the second driving mode, the control circuits of the systems make transition of the driving mode from the second driving mode to the first driving mode while gradually changing the current command values of the control circuits’ own systems toward the current command values before the adjustment.

摘要： A vehicle steering system includes a rotation restriction mechanism that restricts a rotation amount of a steering member within a predetermined angle. The rotation restriction mechanism includes at least one plate element that is interposed between a rotatable element, which is coaxially rotatable together with a rotary shaft of the steering member, and a non-rotatable element, and that is rotatable relative to the rotary shaft. Light projecting units are provided at one of the rotatable element and the non-rotatable element, and light receiving units are provided at the other one of the rotatable element and the non-rotatable element. The at least one plate element has light transmission portions that allows transmission of light that is emitted from the light projecting units and that enters the light receiving units when a rotation angle of the at least one plate element is a predetermined angle.

摘要： A four-wheel steering control system includes; a torque sensor that detects a steering torque based on an operation of a steering member; a steering angle sensor that detects a steering angle; a steering assist control unit that calculates an assist force for steering front wheels based on the value detected by the torque sensor; and a steered system control unit that executes steered control on rear wheels based on the value detected by the steering angle sensor or the value detected by the torque sensor. When it is determined that there is a failure in a function of the steering assist control unit, the steered system control unit executes the steered control such that the rear wheels are steered only on the side where the steered angle of the rear wheels is opposite in phase from the steering angle of the steering member.

摘要： A vehicle control apparatus executes automated cruise control under which a steering apparatus is controlled to make a vehicle perform automated cruise. The vehicle control apparatus sets a curvature radius difference threshold used in a process for determining whether to start automated cruise control, based on a transverse deviation of the vehicle. The vehicle control apparatus does not start the automated cruise control when the absolute value of a curvature radius difference is larger than the curvature radius difference threshold. The curvature radius difference is a difference between a travelling path curvature radius and a lane curvature radius, the travelling path curvature radius being a curvature radius of a travelling path of the vehicle and the lane curvature radius being a curvature radius of a lane in which the vehicle is travelling.

摘要： The absolute value of a steering torque detected by a steering torque sensor is compared with a predetermined threshold. When the absolute value of the detected steering torque is smaller than the threshold, a steering reaction force is controlled on the basis of the steering torque; whereas, when the absolute value of the detected steering torque is larger than or equal to the threshold, the steering reaction force is controlled using a detected reaction motor current value as a reference value.
