PROBLEM TO BE SOLVED: To perform highly reliable steer-by-wire steering operation while reducing the cost of a device.SOLUTION: In the steering device, a relative rudder angle is obtained by a resolver for controlling rotation of a steering reaction motor and/or a resolver for controlling rotation of a turning motor, a reference value deciding part decides on a reference value of the obtained relative rudder angle when a straight moving state determining part determines that the vehicle is in a straight driving state, and an absolute rudder angle calculating part calculates an absolute rudder angle by accumulating a relative rudder angle obtained with the decided reference value as a start point. |
