Abstract
A control device of a marine propulsion device, which has an engine and a propeller and is mounted on a hull. The control device includes a processor, and a non-transitory storage medium having program instructions stored thereon. The execution of the program instructions by the processor causes the control device to acquire a rotation speed of the engine or a rotation speed of the propeller, acquire a torque of the engine, acquire a speed of the hull, and determine whether a ventilation of the engine has occurred based on at least two among the acquired rotation speed, the acquired engine torque, and the acquired hull speed.
Claims11
A control device of a marine propulsion device that has an engine and a propeller and is mountable on a hull, the control device comprising:
- a processor, and
- a non-transitory storage medium having program instructions stored thereon, execution of which by the processor causes the control device to
- acquire a rotation speed of the engine or a rotation speed of the propeller,
- acquire a torque of the engine,
- acquire a speed of the hull, and
- determine whether a ventilation of the engine has occurred based on at least two among the acquired rotation speed, the acquired engine torque, and the acquired hull speed.
A method of controlling a marine propulsion device that has an engine and a propeller and is mountable on a hull, the control method comprising:
- acquiring a rotation speed of the engine or a rotation speed of the propeller;
- acquiring a torque of the engine;
- acquiring a speed of the hull;
- and
- determining whether a ventilation of the engine has occurred based on at least two among the acquired rotation speed, the acquired engine torque, and the acquired hull speed.
A marine vessel, comprising:
- a marine propulsion device that has an engine and a propeller, and is mounted on a hull of the marine vessel;
- and
- a control device that includes
- a processor, and
- a non-transitory storage medium having program instructions stored thereon, execution of which by the processor causes the control device to
- acquire a rotation speed of the engine or a rotation speed of the propeller,
- acquire a torque of the engine,
- acquire a speed of the hull, and
- determine whether a ventilation of the engine has occurred based on at least two among the acquired rotation speed, the acquired engine torque, and the acquired hull speed.
