[Problem]
An object of the present invention is to provide an electric power steering apparatus that suppresses the vibration of the operating member such as the handle and improves the steering feeling due to the characteristic compensation of the assist map, without of the change of the PI-control gain in the current control section.
[Means for Solving the Problem]
The present invention is an electric power steering apparatus that calculates a current command value with reference to an assist map inputting a steering torque and assist-controls a steering system of a vehicle by driving a motor based on the current command value, comprising: a first compensating section provided at a front stage of the assist map; and a second compensating section provided at a rear stage of the assist map; wherein the current command value is calculated with a characteristic of which sloping increases for an absolute value of the steering torque being inputted into the first compensating section and is outputted from the second compensating section, and vibrations of operating members are suppressed.
