Ship control device, a ship control method, and a ship control program

A ship control method, comprising:

• obtaining operation input from each of a first operator used in a low-speed navigation control mode and a second operator used in a high-speed navigation control mode,
• determining a target direction or a throttle opening based on the operation input,
• wherein the low-speed navigation control mode includes a manual operation control mode by operation of the first operator and an automatic navigation control mode for holding a heading using the target direction, or the throttle opening,
• setting the target direction or the throttle opening used for the automatic navigation based on the operation input from the first operator in the automatic navigation control mode,
• wherein the first operator is further configured to receive an operation input for enabling an intermittent throttle control, and
• generating an intermittent throttle signal having a High level and a Low level when the intermittent throttle control is enabled.

A non-transient computer-readable recording medium, recording a ship control program, enabling a computer to:

• acquire operation input from each of a first operator used in a low-speed navigation control mode and a second operator used in a high-speed navigation control mode,
• determine a target direction or a throttle opening based on the operation input,
• wherein the low-speed navigation control mode includes a manual operation control mode by operation of the first operator and an automatic navigation control mode for holding a heading using the target direction, or the throttle opening,
• set the target direction or the throttle opening used for the automatic navigation based on the operation input from the first operator in the automatic navigation control mode,
• wherein the first operator is further configured to receive an operation input for enabling an intermittent throttle control, and
• generate an intermittent throttle signal having a High level and a Low level when the intermittent throttle control is enabled.
