Motorcycle Brake Control System for Rider Comfort and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle braking systems with front and rear wheel interlocking brakes often result in excessive braking force, discomfort for riders due to ineffective brake pressure modification, and instability, especially for inexperienced riders, as they cannot adjust brake distribution according to their input, leading to unpleasant driving experiences and potential vehicle instability.
Innovation Solution
A motorcycle braking device with a control system that measures brake input pressure and applies an additional target pressure to both the front and rear wheels, allowing for dynamic adjustment of brake pressure based on rider input and vehicle state, ensuring balanced deceleration and stability while minimizing discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the brake is controlled based on the map on the ideal brake distribution, then the brake distribution of front and rear wheels is adjusted to the ideal distribution, but the braking force becomes excessively large and the rider feels discomfort
Solution Approach 1:
The brake pressure ratio is made dynamically adjustable based on rider input rather than being fixed by a preset map. The control device calculates target brake pressures for front and rear wheels based on the actual brake manipulation input from the rider, allowing the system to adapt to different riding conditions and rider preferences while maintaining proper brake distribution balance
Solution Approach 2:
The system incorporates feedback from the rider's brake manipulation input to dynamically adjust the brake pressure distribution. By monitoring the brake manipulation device input and using it to calculate target pressures, the system responds to rider intentions in real-time, preventing excessive braking force while maintaining stability
2Reliability
If the brake pressure ratio is changed corresponding to a road surface state, then the braking force is optimized for the road condition, but the rider obtains deceleration different from the previously memorized brake input amount and feels discomfort
Solution Approach 1:
The system uses feedback from the rider's brake manipulation input as the primary basis for calculating target brake pressures. By anchoring the control to the rider's actual input rather than solely to road surface conditions, the system maintains a consistent relationship between rider action and vehicle response, preventing discomfort while still allowing for optimized braking performance
3Adaptability or versatility
If the front and rear wheel brake distribution is adjusted by the rider's brake manipulation, then the rider has control over brake distribution, but inexperienced riders may cause vehicle instability
Solution Approach 1:
The control device automatically calculates and applies the appropriate brake pressure distribution based on the rider's input without requiring the rider to have specialized knowledge. The system serves itself by interpreting the rider's brake manipulation and autonomously determining the optimal front and rear wheel pressure ratio, providing both adaptability and stability
Solution Approach 2:
The system dynamically changes the brake pressure parameters for front and rear wheels based on the rider's input and vehicle conditions. By automatically adjusting these parameters within proper ranges, the system allows brake distribution adaptability while preventing instability that would result from improper rider adjustment
