Vehicle Brake Fluid Detection Logic for False Warning Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle brake fluid consumption detection systems often produce false warnings due to aggressive driving, which can lead to unnecessary alerts and reduce the reliability of brake performance monitoring.
Innovation Solution
A vehicle control system that analyzes throttle values and lateral acceleration to determine aggressive driving behavior, activating a fluid consumption detection enable flag only when both aggressive throttle and lateral acceleration flags are active, thereby preventing false warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fluid consumption detection system is activated to monitor brake fluid consumption, then braking performance monitoring is improved, but false warnings are generated during aggressive driving
Solution Approach 1:
The system performs preliminary detection of aggressive driving conditions by monitoring throttle position and lateral acceleration before the fluid consumption detection is activated. This preliminary action allows the system to anticipate and prepare for conditions that would cause false warnings, enabling it to suppress the warning indicator proactively rather than reactively
Solution Approach 2:
The patent introduces an intermediary control system that mediates between the fluid consumption detection logic and the warning indicator display. This intermediary layer analyzes driving conditions and selectively gates the warning output, allowing the system to filter out false warnings while maintaining genuine safety alerts
2Speed
If the detection logic is simplified to provide immediate warnings, then response time is improved, but false warnings increase during aggressive throttle applications
Solution Approach 1:
The system performs preliminary detection of aggressive driving conditions by monitoring throttle position and lateral acceleration before the fluid consumption detection is activated. This preliminary action allows the system to anticipate and prepare for conditions that would cause false warnings, enabling it to suppress the warning indicator proactively rather than reactively
Solution Approach 2:
The warning suppression is dynamically adjusted based on real-time driving conditions. The system continuously monitors throttle position and lateral acceleration, and the suppression state changes dynamically as conditions change, allowing the system to adapt its behavior to current driving scenarios rather than using a static approach
