Utility Vehicle ABS Control for Automatic Re-Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility vehicle drivers often forget to engage the anti-lock braking system (ABS) in response to changing terrain and driving conditions, leading to potential skidding and loss of control, as they must manually re-engage it after disengagement.
Innovation Solution
A utility vehicle braking system with an anti-lock braking control module that automatically engages the ABS mode based on predetermined conditions such as vehicle speed, terrain, and environmental factors, ensuring continuous engagement without user intervention when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ABS is manually disengaged by the user, then the user has control over when ABS is active, but the user may forget to re-engage it leading to reduced safety
Solution Approach 1:
The ABS control module automatically monitors driving conditions and re-engages the ABS system without user intervention when predetermined conditions are detected, allowing the system to serve itself by detecting when ABS functionality is needed based on terrain and driving parameters
Solution Approach 2:
The system continuously monitors driving conditions through sensors and feedback mechanisms, comparing actual conditions against predetermined thresholds to automatically determine when ABS should be engaged or disengaged, creating a closed-loop control system
2Reliability
If the ABS is automatically engaged based on predetermined conditions, then safety is improved, but the system complexity increases
Solution Approach 1:
The ABS control module performs multiple functions including monitoring driving conditions, determining when predetermined conditions are met, automatically engaging/disengaging ABS, and storing operational data, allowing a single component to handle diverse tasks that would otherwise require separate systems
Solution Approach 2:
The patent combines the ABS control logic, condition monitoring, and engagement decision-making into a single integrated control module, merging multiple functions into one unified system rather than using separate components for each function
3Reliability
If the ABS control module stores operational data, then system reliability is improved through better monitoring, but the device complexity increases
Solution Approach 1:
The control module's data storage capability serves multiple purposes including monitoring system operation, detecting predetermined conditions, tracking ABS engagement history, and providing diagnostic information, making the storage function multi-purpose rather than dedicated to a single task
