Dual-Sensor Tire Explosion Detection for Heavy-Duty Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire explosion detection systems in heavy-duty vehicles lack robustness and have delayed response times, which complicates accurate and timely detection, especially in vehicles with high parametric uncertainty and complex tire conditions.
Innovation Solution
A control unit is configured to obtain sensor data from a first and second tire explosion detection system, where the first system has a lower response time. The control unit detects a tire explosion using the first system, prepares the vehicle for a safety maneuver, and confirms the explosion using the second system before executing the maneuver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single tire explosion detection system is used, then the device complexity is reduced, but the response time increases and reliability decreases
Solution Approach 1:
The detection system is segmented into two independent detection systems with different detection principles. The first system uses a pressure sensor to detect pressure changes, while the second system uses wheel speed sensors to detect speed differences. This segmentation allows each system to specialize in its detection method, improving overall reliability while distributing the complexity across separate modules.
Solution Approach 2:
The system changes the detection parameter from a single parameter (either pressure or speed) to multiple parameters by employing two different detection systems. The first system monitors pressure changes in real-time, while the second system monitors wheel speed differences. This multi-parameter approach enhances detection reliability by providing multiple indicators of tire explosion.
2Loss of time
If a fast response detection system is used, then the response time is reduced, but the detection accuracy may be compromised
Solution Approach 1:
The first detection system using pressure sensors performs preliminary detection of tire explosion by monitoring pressure changes in real-time. When a pressure change is detected, the system immediately alerts the driver and prepares the safety mechanism. This preliminary action ensures the fastest possible response time while the second system continues to provide accurate confirmation.
Solution Approach 2:
The system implements a feedback mechanism where the first detection system's alert triggers the second detection system to provide confirmatory data. The wheel speed sensors continuously monitor and provide feedback on vehicle dynamics, allowing the system to verify the initial pressure-based detection and reduce false alarms, thus maintaining both speed and accuracy.
3Reliability
If dual detection systems are implemented, then detection robustness is improved, but the device complexity increases
Solution Approach 1:
The system merges two different detection approaches (pressure-based detection and speed-based detection) into a unified tire explosion detection system. The control unit integrates data from both the pressure sensor and wheel speed sensors, combining their advantages to achieve robust detection. This merging allows the system to cross-validate detections and improve reliability without requiring completely separate systems.
Solution Approach 2:
The detection system is designed with multi-functionality where the same control unit processes data from both pressure sensors and wheel speed sensors. The system can operate with either detection method independently or in combination, providing universal detection capability. This multi-functional design reduces overall system complexity by using a common control architecture rather than separate dedicated systems.

AI summary
A control unit for early detection and response to a tire explosion in a heavy-duty vehicle, 1) obtains sensor data for a first and a second tire explosion detection system, where the first tire explosion detection system has a lower response time than the second system, 2) detects a tire explosion from the sensor data of the first system, and in response to detecting the tire explosion, prepare the vehicle for a safety maneuver, 3) confirms the tire explosion by detecting the tire explosion from the sensor data of the second system, and in response to confirming the tire explosion, executes the safety maneuver.
