Motorcycle Brake Controller Posture-Based Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycles are prone to instability and potential falling during automatic braking operations due to uneven distribution of braking force, which is not effectively addressed by existing technologies.
Innovation Solution
A controller and brake system that dynamically distribute automatic braking force between the front and rear wheels based on the motorcycle's travel posture, using sensors to detect lean angle and peripheral environment, ensuring appropriate force distribution to prevent falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic braking operation is applied to improve driver safety, then collision avoidance capability is improved, but motorcycle stability deteriorates causing potential falling over
Solution Approach 1:
The braking force is segmented and distributed separately to the front wheel and rear wheel based on the motorcycle's travel posture. The controller independently controls the braking force applied to each wheel, allowing optimization of both collision avoidance and stability by adjusting the distribution ratio according to lean angle and other posture parameters.
Solution Approach 2:
The braking force distribution is made dynamic by continuously adjusting it according to the motorcycle's real-time travel posture. As the motorcycle's posture changes during braking, the controller dynamically modifies the braking force allocation between front and rear wheels to maintain stability while achieving effective deceleration for collision avoidance.
2Reliability
If braking force is applied to wheels for collision avoidance, then safety is improved, but motorcycle posture stability deteriorates
Solution Approach 1:
The system employs feedback by continuously monitoring the motorcycle's travel posture (including lean angle) and using this information to adjust the braking force distribution. The controller receives real-time posture data and modifies the braking force allocation accordingly, creating a closed-loop control system that maintains stability while achieving safety objectives.
Solution Approach 2:
The braking control system changes key parameters including the distribution ratio of braking force between front and rear wheels, and adjusts these parameters based on travel posture. By varying the braking force magnitude and distribution as posture parameters change, the system achieves both safety and stability requirements.
