Ship control method, ship control program, and ship control system, and ship

A ship control method used for a ship including a plurality of power sources including an engine and a motor, having a plurality of propulsion modes in which a power source used for propulsion of a hull is different among the plurality of power sources, and being provided with a clutch at least between the engine and an output section that outputs a propulsive force of the hull, the plurality of propulsion modes including a hybrid propulsion mode in which both the engine and the motor are used for propulsion of the hull, and a motor propulsion mode in which the motor is used for propulsion of the hull, the ship control method comprising:

• when the motor propulsion mode is switched to the hybrid propulsion mode, synchronizing revolutions per minute of the engine with revolutions per minute of the motor before the clutch is switched from a disconnected state to a transmission state;
• and
• controlling a torque of the motor during a torque control period after the revolutions per minute is synchronized.

• and
• a change processor configured to change a correspondence relation between the operation amount and the output value in accordance with the propulsion modes.
