Abstract
A control system for posture control tabs of a marine vessel assists operations of a steering control. The posture control tabs are mounted on a stern of a hull to move up or down to control a posture of the hull. Actuators actuate the respective posture control tabs. When a steering instruction is provided through the steering control, a processor determines the posture control tab to be actuated and controls the actuator corresponding to the posture control tab determined to be actuated so as to change the position of the determined posture control tab.
Claims7
A control system for posture control tabs of a marine vessel, the control system comprising:
- a port side posture control tab and a starboard side posture control tab respectively mounted on a port side and a starboard side of a stern of a hull to move up or down to control a posture of the hull;
- a port side actuator and a starboard side actuator to respectively actuate the port side posture control tab and the starboard side posture control tab;
- and
- a central processing unit configured or programmed to define and function as:
- an instruction acquisition unit to acquire a steering instruction provided by a steering control that provides instructions to control a direction in which the hull moves;
- and
- a processor to, upon the instruction acquisition unit acquiring the steering instruction provided by the steering control at a faster operation speed than a predetermined operation speed, execute a first control to:
- determine a posture control tab to be actuated among the port side posture control tab and the starboard side posture control tab based on a direction of a change in movement of the hull instructed by the steering instruction;
- and
- control one of the port side actuator and the starboard side actuator corresponding to the determined posture control tab so as to change a position of the determined posture control tab.
A method for controlling posture control tabs of a marine vessel, the marine vessel including a steering control that provides instructions to control a direction in which a hull moves, a port side posture control tab and a starboard side posture control tab respectively mounted on a port side and a starboard side of a stern of the hull to move up or down to control a posture of the hull, and a port side actuator and a starboard side actuator to respectively actuate the port side posture control tab and the starboard side posture control tab, the method comprising:
- acquiring a steering instruction provided by the steering control;
- and
- upon acquiring the steering instruction provided by the steering control at a faster operation speed than a predetermined operation speed, executing first control to:
- determine a posture control tab to be actuated among the port side posture control tab and the starboard side posture control tab based on a direction of a change in movement of the hull instructed by the steering instruction;
- and
- control one of the port side actuator and the starboard side actuator corresponding to the determined posture control tab so as to change a position of the determined posture control tab.
