Boat Remote Control Switching Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In boats with multiple remote control units, abrupt changes in control signals occur when switching between control stations, leading to inconsistent operation of propulsion units.
Innovation Solution
The implementation of a switching determination section in each remote control unit, which ensures that switching processing only occurs when both remote control levers are in a neutral state and the remote control selector switch is ON, using microcomputers to manage communication between units and prevent abrupt signal changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple remote control units are provided for operating the same outboard motor, then operational flexibility and ease of operation are improved, but abrupt changes in control signals occur during switching between units
Solution Approach 1:
The switching determination section performs preliminary detection of lever positions and communication status before allowing switching to occur. It checks whether both remote control levers are in the neutral position and whether communication with the other remote control unit is normal, only then permits switching to prevent abrupt control signal changes
Solution Approach 2:
The system continuously monitors the operational state of both remote control units through communication lines and feeds this information back to the switching determination section. Based on this feedback about lever positions and communication status, the system dynamically controls switching timing to maintain stable control signals
2Ease of operation
If remote control levers are not mechanically coupled, then ease of operation and independence of control are improved, but operation amounts of levers can differ and cause abrupt control changes during switching
Solution Approach 1:
The patent replaces mechanical coupling between remote control levers with an electrical/control system. Instead of mechanical linkages that physically synchronize lever positions, the system uses a switching determination section that detects lever positions electrically and controls switching based on communication status, allowing independent lever operation while maintaining consistent control
3Speed
If switching processing occurs without checking communication status, then switching speed is improved, but control signal stability deteriorates due to abrupt changes
Solution Approach 1:
The switching determination section performs preliminary checks of communication status and lever positions before permitting switching. This preliminary action ensures that switching only occurs when communication is normal and both levers are in the neutral position, preventing abrupt control signal changes while maintaining efficient switching

AI summary
There is provided a boat in which the units and control lines for effecting the switching processing of remote control units at the time of switching steering stations can be easily configured, and the system for effecting the switching processing can be easily simplified. A boat includes a first remote control unit connected to boat propulsion units, and a second remote control unit connected to the first remote control unit, the first and second remote control units including remote control levers for operating the boat propulsion units, and remote control selector switches. The first remote control unit has a switching determination section. The switching determination section performs switching processing between the first and second remote control units when the remote control levers of the first and second remote control units are both in the neutral state and the remote control selector switches are in the ON state.
