摘要： As a quotient, which is produced when the value of an assistive current for causing an electric motor to generate an assistive torque is divided by the value of a steering torque detected by a steering torque sensor, becomes greater, a greater phase-lag compensation (smaller phase-lead compensation) is performed on the steering torque detected by the steering torque sensor. Within a region in which the steering sensation is reduced, a greater phase-lead compensation is performed.

摘要： An electric power steering device wherein mechanical friction is electrically provided. A steering torque value is detected by a steering torque sensor according to the operation of a steering wheel. An assist current value is calculated by an assist control section on the basis of the steering torque value. A target current value based on the assist current value is determined. For providing friction to the operation of the steering wheel, a friction control section and a friction torque value/current value conversion section generate a corrected steering torque value. A second corrected target current value is created by correcting a first corrected target current value by a friction current value. The corrected steering torque value is obtained by correcting the steering torque value by a friction torque value. The target current value is generated, resulting in a motor being subjected to driving control.
