Abstract
Provided is an electric power steering apparatus capable of performing steering of a steering wheel with a comfortable steering feeling while stabilizing a vehicle behavior even in a vicinity of a steering neutral position. A first electric power steering apparatus includes a steering torque sensor for detecting a steering torque inputted by a driver, a steering angle sensor for detecting a steering angle of a steering wheel, a steering assist motor for applying a steering assist force to the steering wheel, and a drive control unit for performing drive control of the steering assist motor based on the steering torque and the steering angle. The drive control unit performs drive control of the steering assist motor based on the steering angle detected by the steering angle sensor and hysteresis characteristics related to a steering reaction force associated with a change of the steering angle.
