Claim:
1. An electric power steering device, comprising: an input shaft to which an input torque is applied from a steering wheel; a torque sensor that detects the input torque; a steering mechanism that transmits the input torque to wheels; an electric motor that applies an assist torque to the steering mechanism; and a controller that generates a first output signal by applying a first correction to the input torque and controls the electric motor on the basis of the first output signal while generating a second output signal by applying a second correction to the input torque and outputting the second output signal to a device other than the electric motor; wherein the first correction corresponds to a correction of the input torque that makes a relation between an actual input torque of the input shaft that is measured independently from the torque sensor and an output torque output by the steering mechanism coincide with a set characteristic, and the second correction corresponds to a correction of the input torque that makes the torque detected by the torque sensor coincide with the actual input torque.
