Description

  The present invention relates to a boat propulsion control device including a rudder angle instruction unit that detects a rudder angle of a vessel, a speed detection unit that detects a speed at which the vessel travels, and a draft detection unit that detects draft data of the vessel.

When the ship turns, the torque of the propeller on one end side increases, so the rotational speed of the main propeller driving main machine that drives the main propeller decreases. In this case, in addition to the propulsive force, a lateral force in a plane perpendicular to the axis acts on the ship.
As shown in FIG. 16 (A), this lateral force is significantly increased when turning, compared to when traveling straight. When the lateral force increases, as shown in FIG. 16 (B), the propeller shaft 24 of the ship is bent and the propeller shaft 24 and the stern tube bearing 23 come into contact with each other to cause seizure of the shaft. An accident may occur. Reference numeral 24 'denotes an intermediate bearing.

  In order to reduce such lateral force, in Patent Document 1 (Japanese Patent Laid-Open No. 2006-137334), a rudder angle indicator that detects a rudder angle, a speed detector that detects a speed when a ship travels, and a main propeller. A main propeller drive main machine for driving the main propeller shaft, and based on the detection means of the rudder angle indicator, speed detector, and main propeller drive main machine, the lateral force on the main propeller shaft is calculated, and the lateral force is within a desired value. The propulsion power that falls within the range is stored in the rotation indicator.
