    摘要: A motor driving control method in which when the steering angular velocity is lower than a predetermined reference angular velocity, an actual motor drive current is inferred from a back electromotive voltage and an applying voltage in a three-phase brushless motor, and a limitation on the peak level of each of three-phase alternating current command waves is mitigated by permitting the interval between a pair of intersection points of a peak area of each of the three-phase alternating current command waves with a peak point neighborhood of a triangle wave to become approximately the same length as a dead time.

    摘要: A first system and a second system include a first motor and a second motor for driving a steering mechanism in dependence on the rotational manipulation of a steering wheel. A first ECU and a second ECU mutually monitor abnormalities of the systems each to stop an abnormal system. When the respective systems are normal, the first ECU and the second ECU drivingly control the first motor and the second motor of their own systems to drive the steering mechanism by cooperation of the respective motors. When either one of the both systems is abnormal, the ECU of the other system solely drivingly controls the motor of its own system thereby to drive the steering mechanism. Thus, it can be realized to make the systems low in cost irrespective of the provision of the plural systems.

    摘要: A controller for a brushless motor that suppresses torque reduction resulting from the influence of motor inductance and suppresses the generation of invalid current. A phase advancing angle calculator calculates a delay angle of phases of phase currents with respect to the phases of the phase voltage command and a phase advancing angle corresponding to the delay angle based on the function of the angular velocity and the motor inductance (and armature winding resistance) of the brushless motor. An adder adds the phase advancing angle to the rotation angle provided from the rotation angle calculator to generate the corrected rotation angle. The adder further provides the corrected rotation angle to a two-phase/three-phase converter.
