Motorcycle Brake Control Apparatus Posture Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake control systems for two-wheel vehicles, such as motorcycles, do not effectively adjust intervention levels based on the driving posture of the occupant, leading to potential loss of balance during emergency braking.
Innovation Solution
A control apparatus that utilizes a network of sensors to determine the driving posture of the occupant, adjusting the level of intervention in braking by sensing forces on the seat, steps, steering handle, and wheels, and intervening in the braking process to minimize loss of balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the intervention level in braking is increased to improve stopping performance, then the braking efficiency is improved, but the occupant's balance is compromised when not in a stand-ready posture
Solution Approach 1:
The control apparatus dynamically adjusts the intervention level based on real-time detection of occupant posture. When the occupant is detected to be in a stand-ready posture, full braking intervention is applied; when not in stand-ready posture, the intervention level is reduced. This dynamic adaptation resolves the contradiction by making the braking system flexible rather than fixed, allowing optimal balance between stopping performance and occupant stability.
Solution Approach 2:
The system changes the intervention level parameter based on detected occupant posture conditions. By monitoring forces on the seat, steps, steering handle, and wheels, the system determines whether the occupant is in a stand-ready posture and adjusts the braking intervention parameter accordingly. This parameter change enables the system to optimize both braking efficiency and occupant balance for different operating conditions.
2Reliability
If a fixed high intervention level is used for all braking situations, then emergency stopping capability is maximized, but the system cannot adapt to different occupant postures and conditions
Solution Approach 1:
The control apparatus employs feedback mechanisms by continuously monitoring forces on the seat, steps, steering handle, and wheels to detect occupant posture. This feedback information is used to adjust the intervention level in real-time. The feedback loop ensures that the system maintains reliable emergency stopping capability while adapting to different occupant postures, resolving the contradiction between fixed performance and adaptability.
Solution Approach 2:
The system performs self-adjustment by automatically detecting occupant posture through force sensors and autonomously modifying the intervention level without requiring manual input from the occupant. This self-service capability allows the system to maintain high reliability while achieving adaptability to different conditions.

AI summary
A saddle-ride type vehicle control apparatus includes: an acquiring unit that acquires information indicating a posture of an occupant of a saddle-ride type vehicle; a determining unit that determines a level of intervention in driving of the saddle-ride type vehicle based on the posture of the occupant indicated by the information acquired by the acquiring unit; and an intervening unit that intervenes in the driving of the saddle-ride type vehicle based on a condition of the saddle-ride type vehicle and the level of intervention determined by the determining unit.
