Sailing Boat Autopilot Wind-Angle Control to Avoid Tacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boat autopilot systems do not effectively account for environmental factors such as wind direction and obstacles, leading to potential tacking or jibing issues during navigation.
Innovation Solution
A management module that utilizes wind angle sensors and autopilot systems to generate control commands that keep the sailing boat within a predetermined range of wind angles, avoiding tacking or jibing by considering additional boat data like speed, wind speed, and environmental factors like shallow water zones and obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autopilot module controls the trajectory using basic set points without environmental considerations, then the control system remains simple, but the boat may experience unwanted tacking or jibing due to not accounting for wind direction and environmental factors
Solution Approach 1:
The management module acts as an intermediary between the wind angle sensor and the autopilot module. It receives wind angle data, processes it against predefined thresholds, and generates appropriate control commands to prevent unwanted tacking or jibing, thereby improving reliability without requiring the autopilot itself to be complex
Solution Approach 2:
The system establishes predefined first and second angle thresholds in advance that define the safe operating wind angle range. By having these thresholds predetermined, the management module can quickly compare real-time wind angle measurements against them and generate preventive control commands before unwanted maneuvers occur, rather than reacting after the problem arises
2Reliability
If the management module continuously monitors wind angle and generates control commands to maintain wind angle within thresholds, then unwanted tacking or jibing is prevented, but the system complexity and computational load increase
Solution Approach 1:
The management module monitors changes in the wind angle parameter and only generates control commands when the wind angle approaches or exceeds the predefined first or second angle thresholds. This parameter-based approach allows the system to maintain simplicity by only acting when necessary, rather than continuously complex processing
Solution Approach 2:
The system implements a feedback mechanism where the wind angle sensor continuously provides data to the management module, which compares it against the predefined thresholds and generates corrective control commands when needed. This closed-loop feedback ensures navigation safety while keeping the logic relatively simple through clear threshold-based decision rules

AI summary
The invention relates to a management module for a sailing boat, said sailing boat comprising a wind angle sensor configured to measure the wind angle value of the boat indicating the angle between the wind direction and the sailing direction of the sailing boat, said wind angle value being comprised between −180° and +180°, and an autopilot module configured to receive control commands and to control the trajectory of said sailing boat using said control commands, said management module being configured to receive the wind angle value from said wind angle sensor, generate a control command to control the wind angle of the boat between a first angle threshold and a second angle threshold wherein said first angle threshold and said second angle threshold are greater than or equal to 0° and smaller than or equal to +180° when the wind angle value is between 0° and +180° and greater than or equal to −180° and smaller than or equal to 0° when the wind angle value is between −180° and 0°, and send said generated control command to the autopilot module in order for said autopilot module to control the trajectory of the sailing boat using said control command.
