Abstract
In a marine hybrid system which includes an engine, an electric motor, a thrust generation device, and a clutch mechanism configured to be able to switch connection states therebetween, if it is determined that the engine is in an overload condition, the clutch mechanism is controlled such that a load of the engine is reduced.
Claims9
A marine hybrid system, comprising:
- an engine;
- an electric motor;
- a thrust generation device capable of generating a thrust of a ship by using an output of at least one of the engine or the electric motor;
- a clutch mechanism configured to be able to switch connection states between the engine, the electric motor, and the thrust generation device;
- an overpower determination part for determining whether the engine is in an overload condition;
- and
- a control device for controlling a connection state of the clutch mechanism,
- wherein the control device controls the clutch mechanism such that a load of the engine is reduced, if the overload determination part determines that the engine is in the overload condition.

A control method for a marine hybrid system which includes:
- an engine;
- an electric motor;
- a thrust generation device capable of generating a thrust of a ship by using an output of at least one of the engine or the electric motor;
- and
- a clutch mechanism configured to be able to switch connection states between the engine, the electric motor, and the thrust generation device, the method comprising:
- an overload determination step of determining whether the engine is in an overload condition;
- and
- a control step of controlling the clutch mechanism such that a load of the engine is reduced, if it is determined that the engine is in the overload condition.
