Abstract

See full text

A ship steering device includes a handle which is mechanically separated from a rudder mechanism, a steering angle detecting unit that detects a steering angle of the handle, a reaction force motor that generates reaction force torque to be applied to the handle, and a reaction force controller that controls, based on a steering characteristics map, the reaction force motor in such a way that the reaction force torque in accordance with the steering angle is obtained. The steering characteristics map has characteristics in such a way that the amount of change in an aiming steering torque relative to the steering angle is smaller in a second steering range where the steering angle is larger than that in a first steering range than the first steering region where the steering angle is set in advance from zero.
