PROBLEM TO BE SOLVED: To provide an electric power steering device with good steering feeling by accurately detecting the degree of accumulation of fatigue of a driver.SOLUTION: When a steering state determination means determines that a steering state is in a state other than a holding steering state, the absolute value of the steering torque of a vehicle is integrated, and an integration time is measured. When the measured integration time is equal to or longer than a predetermined time, and the integration value of the absolute values of the steering torque is equal to or higher than a predetermined value, the steering torque is increased by a predetermined amount. When it is determined that a signal from the steering state determination means is in a holding steering state, a holding steering time is measured. When the measured holding steering time is equal to or longer than a predetermined time, the steering torque increased by a predetermined time is decreased by a predetermined amount. |
