Motorcycle Collision Warning Adjusting Output by Bank Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional collision warning systems for motorcycles may output warnings that surprise riders during turns, potentially affecting safety due to unstable vehicle conditions.
Innovation Solution
A processing unit and method that acquires environment and posture information to adjust warning outputs based on the motorcycle's bank angle, ensuring appropriate warnings are given during turns, thereby enhancing rider safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the warning device outputs a warning when collision possibility is detected, then the rider's operation is assisted, but the rider may be surprised in a state where the motorcycle turns with large bank angle and vehicle body becomes unstable
Solution Approach 1:
The system changes the warning output parameters based on the bank angle parameter. When the bank angle exceeds a predetermined threshold, the warning device suppresses or modifies the warning output. This dynamic parameter adjustment resolves the contradiction by adapting the warning behavior to the motorcycle's operational state, ensuring reliability when stable while preventing rider surprise during unstable turning conditions
2Loss of information
If the warning device outputs warnings based on environment information, then collision possibility is recognized, but inappropriate warnings may be generated during unstable vehicle states
Solution Approach 1:
The warning device performs multiple functions: it processes environment information for collision detection and simultaneously processes posture information for warning suppression control. By integrating these functions, the system ensures that warnings are only output when both collision risk and vehicle stability conditions are appropriate, thereby improving warning appropriateness while fully utilizing available information

AI summary
The invention obtains a processing unit and a processing method capable of improving a rider's safety. The invention also obtains a collision warning system that includes the processing unit. The invention further obtains a motorcycle that includes the collision warning system.A processing unit (20) includes: an acquisition section (21) that acquires environment information corresponding to output of an environment detector (11); a determination section (22) that determines presence or absence of a possibility of a collision on the basis of the environment information; and a control section (23) that makes a warning device (30) output a warning in the case where the determination section (22) determines that there is the possibility of the collision. During travel of the motorcycle, the acquisition section (21) acquires posture information related to a bank angle of the motorcycle, and the control section (23) changes the warning output by the warning device (30) in accordance with the posture information.
