Abstract

There is provided an automatic steering device with which a heading can be stably controlled even under powerful disturbance. The control computer 8 outputs an ordered rudder angle calculated based on the drift angle and the turning angular velocity. The angular velocity inversion timing acquisition component 21 acquires a timing at which the turning angular velocity changes from a direction in which a divergence of the drift angle from zero increases to a direction in which the divergence decreases. The steering stop command component 22 orders a steering stop based on the above-mentioned timing. The steering gear controller 10 controls a steering gear such that it changes a rudder angle of the steering gear based on the ordered rudder angle, and such that it does not change the rudder angle while a command of the steering stop has been received.
