Abstract

An engine control device is provided with a main operation unit, an auxiliary operation unit, a changeover switch, and an engine control unit. The main operation unit is capable of performing an operation of changing a rotation speed of a propulsion engine mounted on a ship. The auxiliary operation unit is capable of performing an operation of changing the rotation speed of the engine instead of the main operation unit. The changeover switch is capable of performing an operation of switching between a main ship handling state in which the rotation speed of the engine can be changed by operating the main operation unit and an auxiliary ship handling state in which the rotation speed of the engine can be changed by operating the auxiliary operation unit. The engine control unit stops the engine when the changeover operation unit is operated to switch from the auxiliary ship handling state to the main ship handling state.

Claims (14)

1. An engine control device comprising:

a main operation unit capable of performing an operation of changing a rotation speed of a propulsion engine mounted on a ship;

an auxiliary operation unit capable of performing an operation of changing the rotation speed of the engine instead of the main operation unit;

a changeover operation unit capable of performing an operation of switching between a main ship handling state in which the rotation speed of the engine can be changed by operating the main operation unit and an auxiliary ship handling state in which the rotation speed of the engine can be changed by operating the auxiliary operation unit; and

a control unit that stops the engine when the changeover operation unit is operated to switch from the auxiliary ship handling state to the main ship handling state.

2. The engine control device according to claim 1 , wherein

the control unit stops the engine and shuts off at least a power source of the control unit when the changeover operation unit is operated to switch from the auxiliary ship handling state to the main ship handling state.

3. The engine control device according to claim 1 , wherein

when the control unit starts the engine after stopping the engine,

if the control unit determines that the main operation unit is in a satisfactory condition, the ship handling state is set to the main ship handling state, whereas

if the control unit determines that the main operation unit is not in a satisfactory condition, the ship handling state is set to the auxiliary ship handling state.

4. The engine control device according to claim 1 , wherein

at least two propulsion engines mounted on the ship are provided,

when the control unit determines that the operation of the main operation unit toward one of the engines cannot be performed satisfactorily, the control unit reduces the rotation speed of said engine, while reducing the rotation speed of the other engine.
