In a power steering system, when power is on, a normal mode process is executed and a target rotational speed is set based on a rotational speed map for a normal mode. When the normal mode process is being executed, if a first mode switching condition that a detected vehicle speed is equal to or lower than a prescribed value, the absolute value of a detected steering angle is equal to or greater than a prescribed value, and the absolute value of a detected steering, angular velocity is equal to or less than a prescribed value is satisfied, the target rotational speed is set based on a rotational speed map for a rack end mode.
