摘要： A multilayer circuit board in which wirings are arranged so that the inductance thereof is reduced. A ground wiring and a power source wiring which are provided in a multilayer circuit board are arranged so that most of the wirings are superposed vertically along a direction of a longer side of the circuit board, and since currents flow in an opposite direction to each other in the portions which are superposed, magnetic fields generated by the currents so flowing are canceled by each other. Similarly, a W-phase wiring, a V-phase wiring and a W-phase wiring are also arranged so that the wirings are partially superposed along their longer side direction vertically, and magnetic fields generated by currents flowing in the portions which are superposed vertically are canceled by one another. By this, the inductance of the wirings can be reduced by increasing a mutual inductance between these wirings.

摘要： An angle computing section determines an angle of a rotor, and an angular velocity computing section determines angular velocity of the rotor. A command current computing section determines, from a steering torque and vehicle velocity, command currents and taken along d-q axes. An open loop control section determines, from command currents and angular velocity, command voltages taken along the d-q axes in accordance with motor circuit equations. A d-q axis/three-phase conversion section converts the command voltages into command voltages of three phases. A φ computing section determines the number of armature winding flux linkages included in a motor circuit equation from a q-axis command voltage, the current value detected by a current sensor, and the angular velocity. Circuit resistance including armature winding resistance R included in the motor circuit equation may also be determined by means of the same configuration.

摘要： When one of six FETs has short-circuit faulted, a controllable region identification unit stops driving of an electric motor, and then performs processes for determining whether a short-circuit fault has occurred, and when a short-circuit fault has occurred, for identifying the position of the FET that has short-circuit faulted based on phase voltages (induced voltages) VU, VV, and VW of phases. When the position of the FET that has short-circuit faulted is identified, the controllable region identification unit performs a controllable region identification process. In detail, the controllable region identification unit identifies a “possible region,” an “indeterminate region,” and a “impossible region” based on phase voltages VU, VV, and VW of the phases.

摘要： A command current setting portion has a target value corrector that calculates d-axis and q-axis current command values idc, iqc that are to be supplied to an open-loop controller, based on d-axis and q-axis current target values id*, iq*. When d-axis and q-axis voltage target value vd*, vq* calculated from the d-axis and q-axis current target values id*, iq* by the motor circuit equations exceed a voltage limit, this target value corrector 26 corrects the d-axis and q-axis current target values id*, iq* by the field weakening control such that d-axis and q-axis voltages vd, vq and d-axis and q-axis currents id, iq satisfy √(vd2+vq2)≦Vlim and √(id2+iq2)≦Ilim respectively. The d-axis and q-axis current command values idc, iqc are obtained by this correction.
