Personal Watercraft Passenger Detection Trim Control

The patent applies feedback by using a passenger detection sensor to sense the presence of passengers and providing this information back to the controller, which then adjusts the trim angle accordingly. This closed-loop feedback mechanism enables the system to adapt the body attitude based on actual passenger conditions rather than relying solely on speed detection.

The patent implements dynamics by making the trim angle adjustable and variable based on different operating conditions (number of passengers). The controller dynamically changes the trim angle within a predetermined range according to passenger detection, allowing the system to optimize performance for different loading scenarios rather than maintaining a fixed trim setting.

The patent applies self-service by enabling the system to automatically detect passenger presence and adjust trim angle without requiring manual intervention or complex user input. The sensor-based automatic detection and controller-driven automatic adjustment eliminate the need for passengers to manually configure settings, simplifying operation while maintaining comfort optimization.

The patent implements parameter changes by varying the trim angle parameter within a predetermined range based on passenger detection. Instead of requiring complex reconfiguration or multiple fixed settings, the system continuously adjusts the trim angle parameter in response to sensor input, providing optimized comfort for different passenger conditions through simple parameter variation rather than system complexity.

The patent resolves this contradiction by introducing a passenger detection sensor that provides feedback about the number of passengers to the controller. This feedback mechanism enables the system to automatically adjust the trim angle in response to actual passenger conditions, transforming the control mechanism from a simple fixed-setting system to an adaptive system that maintains favorable body attitude for multiple passengers without requiring complex manual control.

The patent applies self-service by enabling the system to automatically sense passenger presence and adjust trim angle without requiring passenger intervention. The automatic detection and adjustment mechanisms allow the system to self-optimize for passenger comfort while maintaining relatively simple control architecture, eliminating the need for passengers to manually configure settings.
