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.
