    摘要： Disclosed is a vehicle steering apparatus (1; 301) equipped with a control device (12; 322) which controls the actuation of an electric motor (18; 317). First and second housings (23, 24 325, 312), which are in contact with each other, partition off an accommodation chamber (100; 324) which contains the control device (12; 322). The first housing (23; 325) is at least one part of the motor housing (25; 323). The first housing (23; 325) includes a first interior wall surface (101; 401) which partially partitions the accommodation chamber (100; 324). The second housing (24; 312) includes a second interior wall surface (102; 402) which partially partitions the accommodation chamber (100; 324). The first and the second interior wall surfaces (101, 102; 401, 402) are opposite each other with respect to the axial direction (X1) of a rotatable shaft (37; 352) of an electric motor (18; 317). The second interior wall surface (102; 402) includes the flat annular surface that surrounds a central axis (C1) of the rotatable shaft (37; 352) and an extension (C2) of the central axis (C1). The flat circular surface is orthogonal to the central axis (C1) and the extension (C2) of same.

    摘要： An angle calculator detects a rotation angle θa of a rotor. A three-phase/d-q axis converter outputs detected current id, iq on d-q coordinate axes by making a conversion, based on a corrected detection angle θc obtained by adding or subtracting an amount of detection deviation from a time point of current detection to or from the detection angle θa. A command current calculator calculates command current id*, iq* on the d-q coordinate axes based on a steering torque T and a speed S. A feedback controller calculates command voltages vd, vq on the d-q coordinate axes based on the command current id*, iq* and the detected current id, iq. A d-q axis/three-phase converter converts the command voltages vd, vq into three-phase command voltages, based on a corrected detection angle θb obtained by adding an amount of detection deviation from a time point when a motor is driven to the detection angle θa. The deviation can be eliminated by the command voltages, and the motor can be driven with high precision.

    摘要： In a motor control device, a control calculation unit obtains a phase voltage instruction value. A current detecting unit detects an electric current which flows into the brushless motor. A rotational position detecting unit detects the rotational position of a rotor in the brushless motor. A correction unit corrects the phase voltage instruction value based on the detection results of the current detecting unit and the rotational position detecting unit so that a dependency of a ratio on an electric angle shown by a secondary harmonic component of the ratio concerning the electric angle of the brushless motor. The ratio is a ratio of a q-axis or d-axis component of the electric current, which flows into the brushless motor, to a q-axis or d-axis instruction value. A driving unit drives the brushless motor based on the phase voltage instruction value after the correction by the correction unit.
