Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle braking systems struggle to optimize braking force distribution between the front and rear wheels, especially when the wheels are not locked, leading to inadequate braking force generation suitable for the carrying weight.
Innovation Solution
A braking system that includes a first and second hydraulic pressure supply mechanism, a G sensor, and a control unit to adjust hydraulic pressure based on detected weight, ensuring suitable braking force generation even when the wheels are not locked, by using an association mechanism that controls the hydraulic pressure to the braking force generating mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the braking force distribution is controlled in accordance with the lock state of the front wheel and rear wheel, then the braking force distribution can be optimized when the wheels are locked, but the braking force distribution cannot be optimized when the wheels are not locked
Solution Approach 1:
The G sensor preliminarily detects the carrying weight of the motorcycle before braking operation, and the control unit preliminarily determines the appropriate braking force distribution ratio based on the detected weight. This preliminary action enables the braking system to be pre-configured with weight-appropriate braking forces before the braking event occurs, eliminating the need to wait for wheel lock detection.
Solution Approach 2:
The patent replaces the mechanical wheel lock detection method with an electronic sensing system (G sensor) that directly measures the carrying weight. This substitution allows for continuous, real-time weight detection without requiring the wheels to be locked, enabling the control system to adjust braking force distribution based on actual weight conditions.
2Ease of operation
If a fixed braking force distribution is achieved between front wheel and rear wheel, then the braking system is simple to control, but the braking force cannot be optimized according to the carrying weight
Solution Approach 1:
The braking system performs self-adjustment of braking force distribution based on the carrying weight detected by the G sensor. The control unit automatically modifies the braking force distribution ratio according to the detected weight without requiring manual intervention from the rider, enabling the system to adapt to different loading conditions while maintaining simple operation.
Solution Approach 2:
The braking force distribution ratio is made dynamic rather than fixed. The control unit continuously adjusts the braking force distribution based on the carrying weight detected by the G sensor, allowing the system to transition from a static fixed distribution to a dynamic weight-adaptive distribution while maintaining operational simplicity.

AI summary
A braking system for a motorcycle, including a first braking force generating mechanism (35) which generates a braking force when hydraulic pressure is supplied from a first hydraulic pressure supply mechanism (40a), a second braking force generating mechanism (36)which generates a braking force when hydraulic pressure is supplied from a second hydraulic pressure supply mechanism (40b), and an association mechanism (21) which supplies hydraulic pressure to the first braking force generating mechanism (35) when an operation member (13) for operating the second braking force generating mechanism (36) is operated. A sensor (22) detects a weight of the motorcycle, wherein when the weight of the motorcycle is greater than a predetermined weight, the control unit (28) adjusts and controls so as to increase hydraulic pressure supplied to the first braking force generating mechanism (35) by the association mechanism (21).
