Tire Sensor ID Assignment via Brake Control Device Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire sensor systems for vehicles, particularly trucks and tractors, require manual and time-consuming processes to associate tire pressure sensor unique IDs with wheel locations, both during initial installation and when replacing tires, which is inefficient and adds steps to the assembly process.
Innovation Solution
A controller system with brake control device ports and a processing unit that transmits control signals in a predetermined event sequence to identify tire sensors based on motion values, automatically assigning unique sensor IDs to specific wheel locations by correlating acceleration values with predetermined sequences, eliminating the need for manual ID updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual updating of central controller with tire pressure sensor unique ID is used, then accurate association between sensor and wheel location is achieved, but time consumption and labor effort increase significantly
Solution Approach 1:
The system enables self-service by allowing the tire pressure sensor to automatically transmit its unique ID to the central controller through the brake control device, eliminating the need for technician intervention. The sensor autonomously identifies itself and associates with the correct wheel location based on the sequential signal transmission process.
Solution Approach 2:
The manual mechanical process of technician intervention is replaced with an automated electronic communication system. The central controller transmits electronic signals through brake control devices to sensors, which automatically respond with their unique IDs, substituting human labor with an electronic identification protocol.
2Loss of information
If manual activation and ID retrieval process is implemented, then tire pressure sensor identification is achieved, but assembly line efficiency is reduced
Solution Approach 1:
The system performs preliminary action by having the central controller proactively transmit identification signals to sensors during the assembly process. The sensor IDs are retrieved automatically as part of the assembly workflow rather than requiring separate manual activation steps, integrating the identification process into the existing assembly sequence.
Solution Approach 2:
The identification process continues seamlessly with the assembly line operations. As the controller systematically queries each sensor in sequence, the useful action of ID retrieval occurs continuously without interrupting the assembly flow, maintaining productivity while achieving complete sensor identification.
3Reliability
If technician intervention is required for sensor activation and ID communication, then accurate sensor identification is achieved, but process complexity increases
Solution Approach 1:
The brake control device serves multiple functions: it acts as both a brake control component and a communication intermediary for sensor identification. The existing brake control device infrastructure is utilized for dual purposes, eliminating the need for separate identification hardware and reducing overall system complexity.
Solution Approach 2:
The brake control device functions as an intermediary between the central controller and the tire pressure sensor. It receives identification signals from the controller and relays them to the sensor, which then returns the unique ID through the same intermediary, simplifying the communication architecture by using existing components as mediators.

AI summary
Various embodiments of an apparatus and method for configuring a tire sensor system are disclosed. In one embodiment, the method begins with rotating a plurality of tires on a vehicle. The tire sensor associated with a first wheel location generates a data transmission in response to the rotation of the plurality of tires, the data transmission comprising at least a unique sensor identification and a motion value. The controller transmits a brake control device control signal in a first predetermined event sequence to a first brake control device associated with the first wheel location. The controller receives the tire characteristic signal and assigns the unique sensor identification with the first wheel location in response to determining the motion value of the tire characteristic signal corresponds with the first predetermined event sequence.
