PROBLEM TO BE SOLVED: To provide a vehicular steering apparatus capable of reducing the steering force and steering amount of a driver to thereby secure comfort in a steering feeling caused to the driver.SOLUTION: A vehicular steering apparatus 11 includes: a steering torque sensor 25 for detecting steering torque TRQ generated in a steering system of a vehicle; a steering assist motor 27 for providing the steering system with assist torque; an integral processing part 203 for applying an integral to the steering torque TRQ; a target torque calculation part 209 for calculating a target steering angular velocity TSTRV on the basis of an integral value of the steering torque TRQ obtained by the integration processing, and calculating weighted target torque on the basis of the target steering angular velocity TSTRV; and an EPS control device (a control part) 51 for controlling driving of the steering assist motor 27 by using a weighted target current value corresponding to the weighted target torque.SELECTED DRAWING: Figure 1

    【課題】運転者における操舵力及び操舵量を低減することで、運転者に与える操舵感の快適性を確保可能な車両用操舵装置を提供する。【解決手段】車両用操舵装置11は、車両の操舵系に発生する操舵トルクTRQを検出する操舵トルクセンサ25と、操舵系に補助トルクを付与する操舵補助モータ27と、操舵トルクTRQの積分処理を行う積分処理部203と、積分処理により得られる操舵トルクTRQの積分値に基づいて目標舵角速度TSTRVを算出すると共に、目標舵角速度TSTRVに基づいて加重目標トルクを算出する目標トルク算出部209と、加重目標トルクに応じた加重目標電流値を用いて操舵補助モータ27の駆動制御を行うEPS制御装置(制御部)51と、を備える。【選択図】図1
