Abstract
An electric power steering device includes a basic return command value calculation unit configured to calculate a basic return command value in a direction returning the steering wheel to a neutral position, on the basis of detection results of a steering angle detector detecting a steering angle of the steering wheel, a first correction gain calculation unit configured to calculate a first correction gain correcting the basic return command value, on the basis of detection results of a vehicle speed detector detecting vehicle speed, and a second correction gain calculation unit configured to calculate a second correction gain correcting the basic return command value, on the basis of a change amount of the steering torque detected by the torque sensor. The basic return command value is corrected by the first and second correction gains so as to calculate a return command value. The return command value is added to the assist command value so as to drive the electric motor.
