Title:
SHIP STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/168802
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a ship steering device whereby course-change calibration can easily be performed. In a ship steering device (7), when port and starboard forward-backward propellers (4) are each rotated by a rotation operation of a joystick lever (10), an ahead/reverse propulsion ratio or respective speed of the port and starboard forward-backward propellers (4) is changed by a tilting operation of the joystick lever (10), and a correction execution switch (10a) is operated during course-change calibration, a thrust generated in accordance with the changed ahead/reverse propulsion ratio is set as a correction coefficient, or, of the thrust generated by the changed speed (Npn, Nsn) of the port and starboard forward-backward propellers (4), the thrust of the port and starboard forward-backward propellers (4) due to the tilting operation is set as the correction coefficient (Cp, Cs), and the course-change calibration is thereby performed.
