Ship shift control device and ship shift control method

摘要

An engine and a gear box are reliably protected even when a plurality of engines are set and the engine is operated only with a specific engine. An LP sensor (102, 202) for detecting a shift state of forward, reverse, or neutral from an operation state of a throttle lever corresponding to each of the plurality of engines (100, 200), and the plurality of engines A controller (10) for controlling the engine, the controller detects the simulated ship speed from the rotational speeds of the plurality of engines, and from the state where the ship is operated by some of the plurality of engines, When trying to operate the remaining engine in the neutral shift state, if the simulated ship speed is higher than the first judgment value, the corresponding engine shift-in prohibition flag is set and the remaining engine shifts. In-control is prohibited. [Selection] Figure 1
