Adaptive Tire Pressure Alert Thresholds for Performance Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire pressure monitoring systems (TPMS) fail to automatically adjust tire pressure settings based on specific driving environments, leading to unnecessary alerts and potential vehicle damage due to inadequate tire pressure optimization for performance driving conditions.
Innovation Solution
A system that uses a processor to determine the vehicle's proximity to predefined locations and adjust TPMS settings to match alternative tire pressures, reverting to base settings after a predefined distance has been traveled, thereby optimizing tire pressure for the current driving conditions and minimizing unnecessary alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TPMS uses fixed base tire pressure settings, then vehicle safety is ensured on normal roads, but unnecessary alerts occur during performance driving and driver distraction increases
Solution Approach 1:
The TPMS dynamically changes alert thresholds based on vehicle location and driving conditions. The system transitions from static base settings to dynamic alternative settings when performance driving conditions are detected, resolving the contradiction by making the system adaptable rather than fixed.
Solution Approach 2:
The system changes the tire pressure alert threshold parameter from a fixed base value to an alternative value suited for performance driving. This parameter change allows the system to maintain safety while reducing false alerts during different driving conditions.
2Ease of operation
If TPMS uses alternative tire pressure settings for performance driving, then driver distraction is reduced, but vehicle safety may be compromised if base settings are not restored
Solution Approach 1:
The system automatically restores base TPMS settings after a predefined distance is traveled following performance driving conditions. This preliminary restoration action ensures safety is re-established without requiring manual driver intervention.
Solution Approach 2:
The system continuously monitors vehicle location and driving conditions to determine when to switch between base and alternative settings. This feedback mechanism ensures the appropriate settings are active at the right times, maintaining both safety and reduced distraction.
3Reliability
If TPMS continuously monitors and alerts on tire pressure, then vehicle safety is maintained, but system complexity and false alerts increase in varying driving conditions
Solution Approach 1:
The system segments monitoring into different modes: base mode for normal driving with standard alert thresholds, and alternative mode for performance driving with adjusted thresholds. This segmentation reduces false alerts while maintaining safety monitoring.
Solution Approach 2:
The TPMS serves multiple functions by automatically adapting to different driving conditions without requiring separate manual systems. The single system handles both normal and performance driving scenarios, reducing overall complexity while maintaining safety.

AI summary
A vehicle determines that it is within a predefined proximity of a location for which an alternative tire pressure different from a current vehicle tire pressure has been defined. The vehicle changes a tire pressure monitoring system setting to utilize the alternative tire pressure as an alert threshold, responsive to determining that the vehicle is within the predefined proximity. Also, the vehicle determines that the vehicle has traveled more than a predefined distance from the location and, responsive to the vehicle having traveled more than a predefined distance, reverts the tire pressure monitoring system to use base settings for alert thresholds.
