Ship steering device and ship steering method

摘要

A ship steering device capable of steering a hull in an intended direction by correcting an unintended rotation that occurs during an oblique sailing operation regardless of the type and size of the hull. A ship steering device is provided with an elevation angle sensor for detecting the elevation angle α of a hull, a hull speed sensor for detecting the speed V of the hull, a storage means storing the relation among the elevation angle α of the hull, the speed V of the hull, and a correction value K, and a calculation means serving as a correction value determination means, and an operation amount by which a joystick is operated such that the hull does not turn in the state in which the hull is obliquely sailed is determined by the calculation means and used as the correction value K.

主权项

1. A steering method for a ship, comprising:
operating an operation device of the ship sailing with propulsion power from a pair of left and right outdrive devices that are rotatable laterally and actuated by the operation device so as to move the ship laterally leftward and rightward, operating a confirmation device upon confirming that the ship is actually being moved laterally leftward or rightward, wherein the outdrive devices, the operation device, and the confirmation device are connected to a control device, and calculating rotation angles of the left and right outdrive devices at a time of operating the confirmation device by the control device so as to determine the calculated rotation angles as reference rotation angles of the left and right outdrive devices for the lateral movement of the ship.
