Abstract
A control computing unit calculates current axial force of a steering rack based on a turning current. Moreover, the control computing unit calculates lateral axial force of the steering rack based on a lateral acceleration. Then, the control computing unit calculates steering reaction force based on the current axial force at a time of a steering increasing operation of a steering wheel, and calculates the steering reaction force based on the current axial force and the lateral axial force at a time of a steering returning operation of the steering wheel.
