Automatic Tire ID Registration via In-Vehicle Control Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire pressure monitoring systems (TPMS) face challenges in efficiently and accurately registering tire IDs when tire replacements occur, leading to user inconvenience and congestion at facilities, as existing methods require manual correction and registration of new IDs, which can result in incorrect registrations due to multiple vehicles within communication range.
Innovation Solution
An in-vehicle control apparatus and in-facility apparatus system that automatically registers post-replacement tire IDs via a communication network, using an in-vehicle wireless reception section to receive tire IDs from sensor units and transmit them to the in-facility apparatus, ensuring accurate registration and reducing user effort and congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual registration methods (handwritten application, electronic application, push button manipulation) are used to register tire IDs, then users can register tire IDs, but users need to spend time and effort correcting errors and registering each time tires are substituted, causing congestion at facilities
Solution Approach 1:
The system enables self-service automatic registration where the in-vehicle control apparatus autonomously transmits the new tire ID to the in-facility apparatus via wireless communication upon detecting a tire replacement, eliminating the need for manual user intervention in the registration process
Solution Approach 2:
The patent replaces manual mechanical registration methods (handwritten forms, button pressing) with automated electronic wireless communication between the in-vehicle control apparatus and in-facility apparatus, substituting human physical actions with automated digital signal transmission
2Extent of automation
If the in-facility apparatus receives tire IDs directly by wireless communication from sensor units, then automatic registration is achieved, but the apparatus may fail to determine which vehicle's tire ID needs to be registered when multiple TPMS are within communication range
Solution Approach 1:
The in-vehicle control apparatus serves as an intermediary between the sensor unit and the in-facility apparatus, receiving the tire ID from the sensor unit, identifying the associated vehicle, and then transmitting the correct ID to the facility apparatus, thereby resolving the ambiguity of multiple vehicles in range
Solution Approach 2:
The system segments the registration process into distinct functional modules: the sensor unit generates the tire ID, the in-vehicle control apparatus processes and routes the ID to the correct facility, and the in-facility apparatus stores the registered ID, allowing each component to perform its specific function accurately
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system ensures accurate and efficient registration of tire IDs, reducing congestion and saving user time by automatically updating the in-facility apparatus with post-replacement tire IDs, preventing incorrect registrations and streamlining the facility access process.
Implementation Method 1
an in-vehicle wireless reception section that receives a first tire ID from a sensor unit provided in at least one tire of the vehicle
Implementation Method 2
an in-facility wireless reception section that receives the first tire ID wirelessly transmitted directly from the sensor unit

AI summary
An ECU is used to a tire pressure monitoring system of a vehicle. The ECU includes a contact storage portion and a post-replacement ID reporting section. The contact storage portion stores previously a contact of a management computer of a facility that the vehicle uses. The post-replacement ID reporting section transmits a post-replacement tire ID of a tire, which is substituted in the tire replacement, to the contact in the contact storage portion via a communication network when the tire replacement is detected by a tire replacement detection section. The management computer includes a registration change section that registers the post-replacement tire ID in a registration portion upon receiving the post-replacement tire ID.
