Marine Vessel Steering Control Using Turn Duration Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering control systems for marine vessels require complex and repetitive operations to increase the turning amount beyond a predetermined angle, making it difficult to turn the vessel intuitively.
Innovation Solution
A steering control system that includes a controller programmed to increase the turning amount of a marine vessel based on the duration of a predetermined operation state, allowing for intuitive operation by continuing the operation without repeated joystick rotations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the joystick is rotated from the reference position for predetermined rotation to set a turning amount of a predetermined angle, then the marine vessel can be turned to a target orientation, but it is necessary to return the joystick to the reference position and repeatedly rotate it to increase the turning amount, resulting in complex operations
Solution Approach 1:
The patent applies dynamics by making the turning amount dynamically adjustable based on the duration of the operation. Instead of a fixed predetermined angle, the turning amount increases as the operation duration time increases, allowing the system to adapt to the operator's intent in real-time without requiring repeated operations
Solution Approach 2:
The patent changes the parameter of turning amount based on the operation duration time. The control unit adjusts the turning amount as a variable parameter that increases with time, transforming the static predetermined angle into a dynamic value that reflects the continuity of the operator's input
2Ease of operation
If the turning amount is set to a predetermined angle for each joystick rotation, then the control is simple, but it is difficult to turn the marine vessel by an intuitive operation when a larger turning amount is needed
Solution Approach 1:
The patent implements continuity of useful action by maintaining the operation state as long as the operator holds the joystick in the rotated position. The turning amount continuously increases with operation duration time, allowing the operator to achieve any desired turning amount through a single continuous action rather than multiple discrete operations

AI summary
A steering control system of a marine vessel includes a controller configured or programmed to perform a control to turn the marine vessel so as to change a target orientation in an automatic marine vessel maneuvering mode to hold a course in which the marine vessel is moved to the target orientation, and an operator to receive an operation to cause the controller to turn the marine vessel to the target orientation. The controller is configured or programmed to perform a control to increase a turning amount of the marine vessel according to an operation duration time in which a predetermined operation state of the operator continues.
