Vehicle Body Behavior Control Device Gradient Brake Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle body behavior control devices for motorcycles and similar vehicles face instability due to uneven braking forces applied to wheels when road surface gradients change, leading to unstable vehicle behavior.
Innovation Solution
A vehicle body behavior control device that adjusts interlocking brake operations based on the gradient value of the road surface, using a brake mechanism and control system to distribute braking forces more effectively between wheels, thereby stabilizing vehicle behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If interlocking brake operation is controlled based only on deceleration of the vehicle body, then the brake operation is simple to implement, but the braking force becomes excessively large or small when road surface gradient changes, causing unstable vehicle behavior
Solution Approach 1:
The control part modifies the brake control parameters by incorporating road surface gradient information into the interlocking brake operation. When a brake operation is detected, the control part acquires gradient values and adjusts the braking force distribution based on these gradient values, allowing the system to adapt to different road conditions while maintaining stability.
Solution Approach 2:
The system implements feedback by continuously monitoring the road surface gradient and using this information to adjust the brake operation. The control part acquires gradient values during brake operations and uses this feedback to optimize the braking force application, ensuring stable vehicle behavior across varying road conditions.
2Productivity
If braking force is applied to multiple wheels during interlocking brake operation, then vehicle stopping performance is improved, but the braking force distribution becomes unbalanced on gradient road surfaces, leading to unstable vehicle behavior
Solution Approach 1:
The system applies different braking forces to different wheels based on the local road conditions. The control part adjusts the braking force for each wheel individually according to the gradient value, ensuring that each wheel receives the appropriate braking force for its specific position and condition, thereby maintaining overall vehicle stability while achieving effective stopping.
