Marine Vessel Steering Control System Automatic Mode Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering control systems for marine vessels are complex and require a dedicated operator to cancel automatic maneuvering modes, which complicates the system structure.
Innovation Solution
A steering control system that allows vessel operators to cancel automatic marine vessel maneuvering modes by performing predetermined operations, such as moving an operation lever or rotating a steering wheel, without adding a dedicated operator, thereby simplifying the system structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dedicated operator is added to cancel automatic maneuvering mode, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The existing operator components (steering wheel, operation levers) are designed to serve dual purposes: their primary functions for normal vessel operation and an additional function for canceling automatic maneuvering mode. The controller detects specific operations on these existing components to trigger mode cancellation, eliminating the need for a dedicated cancel operator and reducing system complexity while maintaining ease of operation.
2Device complexity
If existing operators are used for canceling automatic maneuvering mode, then the device complexity is reduced, but the reliability of mode cancellation may be affected
Solution Approach 1:
The controller continuously monitors the operational state of existing operators (steering wheel rotations, operation lever positions) and provides feedback to determine when cancellation conditions are met. This feedback mechanism ensures reliable detection of operator actions and accurate execution of mode cancellation, maintaining high reliability while using simplified system structure.
Solution Approach 2:
The system is designed with predetermined cancellation conditions that prevent unintended mode cancellations. By establishing clear, pre-defined operational thresholds and patterns that must be met for cancellation to occur, the system avoids accidental deactivation while maintaining simplicity. The controller only cancels automatic maneuvering mode when specific, predetermined operations are detected, ensuring reliable and intentional mode transitions.

AI summary
A steering control system of a marine vessel includes a controller configured or programmed to perform at least one of a control to automatically steer the marine vessel or a control to automatically change a propulsive force of a propulsion device in an automatic marine vessel maneuvering mode during movement of the marine vessel, and an operator for the marine vessel to perform a predetermined operation. The controller is configured or programmed to cancel the automatic marine vessel maneuvering mode based on an operation performed on the operator by a vessel operator to perform the predetermined operation during the movement of the marine vessel in the automatic marine vessel maneuvering mode.
