Title:
AUTOMATIC SHIP MANEUVERING SYSTEM, SHIP CONTROL DEVICE, SHIP CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/251367
Kind Code:
A1
Abstract:
A ship of this automatic ship maneuvering system is provided with: an actuator that generates a propulsive force and a turning moment; an operation unit; and a ship control device. The ship control device has a manual maneuvering mode in which the actuator is activated on the basis of an input operation accepted by the operation unit, and an automatic maneuvering mode in which the actuator is activated on the basis of the distance between the ship and a communication device of the automatic ship maneuvering system and heading of the ship, without requiring the operation unit to accept an input operation. In the automatic maneuvering mode, a first control in which the rate of decrease in the distance between the ship and the communication device is no greater than a first threshold value, and a second control in which the rate of decrease in the distance between the ship and the communication device is greater than the first threshold value can be carried out.
