[Problem];An object of the present invention is to provide a safe electric power steering apparatus with a good steering feeling that includes a function for getting out from restraint of a lateral flow or a one-sided flow, and enables acquisition of a better effect that a driver's load is reduced in the lateral flow or the one-sided flow.;[Means for solving the problem];A motor current correction value calculating section that corrects a current command value by a motor current correction value based on a motor correction signal comprises a straight running state judging section that judges a straight running state of a vehicle, an adaptive calculating section that calculates and outputs the motor correction signal according to at least a straight running judgment result, a steering angle and an action force, a vehicle speed sensitive gain section that outputs a vehicle speed gain corresponding to a vehicle speed, and an output calculating section that multiplies the motor correction signal by the vehicle speed gain and outputs the motor current correction value, and includes a function for setting thresholds for the motor correction signal and a steering information, and getting out from restraint of the lateral flow or the one-sided flow by condition judgment between the motor correction signal and the steering information and the thresholds. |
