Tire Sensor Assignment via Wireless Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire sensor assignment methods for commercial vehicles are complex and often require manual adjustments, leading to errors in monitoring tire conditions, especially when tire changes occur.
Innovation Solution
A method and device for automatically assigning a tire sensor to a wheel position using wireless communication signals, where the assignment is based on reception parameter values and tire parameter values, allowing for independent determination without pre-existing associations, and is triggered by vehicle movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual adjustment methods are used for tire sensor assignment, then the assignment can be performed with simple equipment, but the complexity of the adjustment process increases and error-free monitoring cannot be ensured
Solution Approach 1:
The system automatically performs tire sensor assignment using reception parameter values from wireless communication signals. The telematics unit independently determines wheel positions and assigns sensors without requiring manual intervention or additional user devices, making the system self-configuring and eliminating human error in the assignment process.
2Ease of operation
If automatic assignment methods are implemented, then the assignment process is simplified and can be performed without tools, but the device complexity increases
Solution Approach 1:
The patent replaces manual mechanical adjustment processes with an automated electronic system. The telematics unit uses wireless communication signals and reception parameter analysis to automatically determine wheel positions and assign tire sensors, substituting the mechanical/manual assignment process with an electronic automated system that leverages existing communication infrastructure.
3Stability of the object's composition
If tire sensors are permanently assigned to wheel positions, then the monitoring system is stable, but the system cannot adapt when tire changes or wheel position swaps occur
Solution Approach 1:
The system transitions from a static permanent assignment to a dynamic automatic reassignment mechanism. When tire changes or wheel position swaps occur, the telematics unit automatically detects the new configuration through wireless communication signals and reception parameter values, and reassigns tire sensors to the correct wheel positions, maintaining both stability during normal operation and adaptability during changes.
4Ease of repair
If additional user devices are required for assignment, then the assignment can be performed with external assistance, but the process becomes more complex and time-consuming
Solution Approach 1:
The system eliminates the need for external user devices or assistance by performing the assignment process autonomously. The telematics unit uses its own wireless communication capabilities to receive signals from tire sensors, analyze reception parameter values, determine wheel positions, and complete the assignment without any external intervention, saving time and simplifying the process.
