PROBLEM TO BE SOLVED: To provide a steering retention determination device for vehicle that can detect steering retention states in various situations or without any error, can detect a steering retention state accurately and instantaneously even if noise is superposed on a signal used for the detection, and can accurately limit a current of a motor, and an electric power steering device mounted with the same.SOLUTION: There are provided: a steering retention determination device that is equipped with at least two steering angle sensors for detecting a steering angle, and a steering state determination part which calculates a hysteresis center value using a hysteresis signal having a hysteresis width set for each steering angle, determines a steering state using the hysteresis center value, and outputs steering information, and detects a steering retention state based upon the steering information; and an electric power steering device mounted with the same.SELECTED DRAWING: Figure 4

    【課題】種々の状況での保舵状態を検出し或いは誤検出せず、検出に使用する信号にノイズが重畳していても正確で即時に保舵状態を検出でき、モータの電流制限を的確に実行できる車両用保舵判定装置及びそれを搭載した電動パワーステアリング装置を提供する。【解決手段】舵角を検出する少なくとも2つの舵角センサと、各舵角に対してヒステリシス幅を設定したヒステリシス信号を用いてヒステリシス中心値を算出し、ヒステリシス中心値を用いて操舵状態を判定し、操舵情報を出力する操舵状態判定部とを具備し、操舵情報を基に保舵状態を検出する車両用保舵判定装置及びそれを搭載した電動パワーステアリング装置である。【選択図】図4
