ELECTRIC POWER STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric power steering device that suppresses vibrations that a steering wheel has in an easy method. ! SOLUTION: There is provided an electric power steering device that drives an electric motor 10 with an assist command value computed on the basis of a detection result of a torque sensor 12 detecting steering torque input from a steering wheel. The an electric power steering device includes: a phase advance correction part 31 which advances the phase of a steering torque signal detected by the torque sensor 12; a specific frequency extraction part 32 which extracts a component of a specific frequency band of the steering torque signal; and a gain multiplication part 37 which corrects a steering torque signal, computed on the basis of the output signal of the phase advance correction part 31 and the output signal of the specific frequency extraction part 32, to a limit value set by a limiter 38 by multiplying the steering torque signal by a gain; and an addition part
