Motorcycle Warning Control Using Helmet Posture Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders of straddle-type vehicles, such as motorcycles, face safety and comfort issues due to frequent unnecessary warnings from existing warning systems, as their body is exposed and prone to hazards, leading to discomfort when warnings are not contextually relevant.
Innovation Solution
A processor and method that integrates a surrounding environment detector, helmet posture direction detector, and alarm system to determine the necessity of warnings based on both environmental and rider posture information, ensuring warnings are only given when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If warning operation is performed in all situations where hazards are detected, then rider safety is improved, but rider comfort deteriorates due to unnecessary warnings
Solution Approach 1:
The system continuously monitors helmet posture direction and uses this feedback to dynamically adjust warning issuance. By comparing real-time posture data with hazard conditions, the system determines whether warnings are necessary, creating a closed-loop control that balances safety and comfort
Solution Approach 2:
The system changes the parameter of warning issuance from a fixed state (always warn when hazard detected) to a dynamic state conditioned on helmet posture angle and duration. This parameter change allows the system to adapt warning behavior based on rider attention state
2Object-affected harmful factors
If warning operation is restricted to reduce unnecessary alerts, then rider comfort is improved, but rider safety may be compromised
Solution Approach 1:
The system performs preliminary assessment of rider attention state through helmet posture detection before deciding whether to issue warnings. This preliminary action ensures that safety-critical warnings are not missed while filtering out unnecessary ones
Solution Approach 2:
Helmet posture direction information serves as an intermediary parameter that mediates between hazard detection and warning issuance. This intermediary allows the system to intelligently filter warnings based on rider state without directly compromising safety
3Object-affected harmful factors
If helmet posture direction detection is added to determine warning necessity, then rider comfort is improved by reducing unnecessary warnings, but device complexity increases
Solution Approach 1:
The helmet posture direction detector serves multiple functions: it monitors rider attention state, determines warning necessity, and potentially tracks rider behavior patterns. This multi-functionality justifies the added device complexity by providing multiple benefits from a single sensor

AI summary
The present invention obtains a processor, a processing method, a warning system, and a straddle-type vehicle capable of improving both the rider's safety and the rider's comfort. A processor (20) includes: an acquisition section that acquires surrounding environment information corresponding to output of a surrounding environment detector (11) during travel of a straddle-type vehicle (100); a determination section that determines necessity of warning operation provided to the rider and generated by the warning system (1) ; and a control section that makes an alarm (30) perform the warning operation in the case where the determination section determines that the warning operation is necessary. The acquisition section further acquires helmet posture direction information corresponding to output of a helmet posture direction detector (13) during the travel of the straddle-type vehicle (100). The determination section determines the necessity of the warning operation on the basis of the surrounding environment information and the helmet posture direction information.
