PROBLEM TO BE SOLVED: To provide a vehicular steering apparatus, including a motor for generating assist torque, capable of preventing a rotation speed of a steering wheel from increasing excessively even if a driver hands off the steering wheel when reversing the steering wheel after starting to rotate the steering wheel for turning a vehicle.SOLUTION: In processing for determining a target rotation speed of a steering wheel (a target steering angular speed), in determining a turning-back control amount, a factor is determined, the factor decreasing with an increase in the steering torque exerted to the steering wheel by a driver. Further, a larger absolute value of the target steering angular speed is set as the absolute value of a virtual steering angle that is a product of the aforementioned factor and a steering angle as an actual rotation angle of the steering wheel increases.SELECTED DRAWING: Figure 3

    【課題】アシストトルクを発生させる電動機を備え、車両を旋回させるために操舵ハンドルを切り出した後、操舵ハンドルを切り戻すとき、運転者が操舵ハンドルから手を放しても操舵ハンドルの回転速度の大きさが過大となることを防ぐことが可能な電動パワーステアリング装置を提供すること。【解決手段】切り戻し制御量を決定するとき、操舵ハンドルの目標回転速度(目標操舵角速度)を決定する処理において、運転者が操舵ハンドルに作用させる操舵トルクが大きくなるほど小さくなる係数を決定し、この係数と、操舵ハンドルの実際の回転角度である操舵角と、の積である仮想操舵角の絶対値が大きくなるほど目標操舵角速度の絶対値を大きな値に設定する。【選択図】図3
