摘要： The present invention provides an electric power steering device enabled to compensate for the influence of the inertia of a steering-assisting-force generating motor on steering with accurate timing even when a steering direction is reversed at high speed. Based on steering torque and a rotation angular speed of a steering-assisting-force generating motor, a steering angular acceleration correspondence value is obtained. The device has means for regulating a gain, which is multiplied to a change acceleration of the steering torque. The motor is controlled so that the steering assisting force is corrected according to a motor output correction value obtained on the basis of the relation between the motor output correction value and the steering angular acceleration correspondence value, which is preliminarily determined and stored in such a way as to compensate for the influence of the inertia on steering, and the obtained steering angular acceleration correspondence value.

摘要： A motor drive circuit (43) outputs a voltage corresponding to a duty ratio of a PWM signal, to an assist motor (30) by controlling electric power supplied from a direct-current power supply (Batt) through PWM. When an MPU (41) that controls the motor drive circuit (43) determines that a determination current value (Ij) obtained by adding a shaft force correction current value (In) to a motor current (I) exceeds a current threshold value (It), the MPU (41) decreases the duty ratio of a low-voltage switching element of the motor drive circuit (43) by multiplying the duty ratio by a duty limit value (Gd). When the MPU (41) performs the determination, the MPU (41) increases the shaft force correction current value (In) based on the vehicle speed (V) of the vehicle.
