Abstract

A ship steering device including: an engine; an auto-drive unit that exerts propulsive power on a ship hull by power from the engine; detection means for detecting a current position and an orientation of the ship hull; a ship steering control device that controls an output of the engine and propulsive power of the auto-drive unit; and a calibration switch that starts calibration of a ship. When the ship steering control device detects that the calibration switch is turned on, the ship steering control device controls the engine and the auto-drive unit to cause the ship hull to move in a predetermined direction or to turn, and if a difference between, for instance, a traveling amount and speed in the predetermined direction and an intended traveling amount and speed exceeds a predetermined value, the ship steering control device corrects control values of the engine and the auto-drive unit.

Claims4

Dependent claims

A ship steering device comprising:

an engine;
a propulsion unit configured to exert propulsive power on a ship hull by power from the engine;
detection means for detecting a current position and an orientation of the ship hull;
a control device configured to control an output of the engine and propulsive power of the propulsion unit;
and
manipulation means configured to start calibration of a ship, wherein
when the control device detects that the manipulation means is turned on, the control device controls the engine and the propulsion unit to cause the ship hull to move in a predetermined direction or to turn, and
if a difference between
a traveling amount and a travelling speed or a turning amount and a turning speed in the predetermined direction and
an intended traveling amount and an intended traveling speed or an intended turning amount and an intended turning speed
exceeds a predetermined value, the control device corrects control values of the engine and the propulsion unit.
