Wheel Registration Apparatus for Automatic TPMS ID Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems (TPMS) require manual registration of ID information for each wheel set during tire replacement, which is time-consuming and inconvenient, especially when the vehicle is not in use.
Innovation Solution
A wheel registration apparatus that includes transmitters on each wheel with a controller to create and transmit unique ID information frames, and a receiver on the vehicle body to automatically register the ID information without the need for a tool, allowing for registration even when the vehicle is stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual registration of ID information is performed during tire replacement, then registration accuracy is ensured, but registration time increases and convenience deteriorates
Solution Approach 1:
The system enables automatic self-registration of wheel ID information through wireless communication between the sensor transmitter on each wheel and the vehicle body receiver. The transmitters automatically transmit their unique IDs when the vehicle is stationary, eliminating the need for manual intervention or specialized tools during tire replacement operations.
Solution Approach 2:
The patent replaces manual mechanical registration processes with wireless electromagnetic communication. Instead of using physical tools or manual input methods to register wheel IDs, the system uses radio frequency communication between transmitters and receivers to automatically capture and store identification information.
2Reliability
If the vehicle is required to be in motion for registration, then signal reception reliability is improved, but registration availability deteriorates
Solution Approach 1:
The system dynamically adapts its operation mode based on vehicle state. It can perform registration operations in both stationary and moving conditions, with the controller adjusting signal reception parameters and processing methods according to whether the vehicle is parked or in motion, thereby maintaining reliability across different scenarios.
Solution Approach 2:
The registration system is designed to function universally across multiple vehicle states. It can register wheel ID information whether the vehicle is stationary during tire replacement or moving during normal operation, making the system adaptable to various operational contexts without requiring separate registration procedures.
3Productivity
If automatic registration is implemented, then registration efficiency is improved, but system complexity increases
Solution Approach 1:
The patent introduces a receiver unit as an intermediary component that mediates between the transmitters on the wheels and the vehicle's central control system. This receiver automatically captures transmitted ID signals, processes the information, and stores it in the appropriate memory locations, simplifying the overall automatic registration process while maintaining efficiency.

AI summary
A wheel registration apparatus applied to a vehicle comprises: a transmitter that is provided on each of the four traveling wheels provided with tires and has a first controller configured to create and transmit a frame including unique identification information; and a receiver that is provided on a vehicle body, receives the frames transmitted by the transmitters provided on the four traveling wheels via a reception antenna in a registration mode, and has a second controller configured to register four pieces of the identification information included in the respective frames as pieces of identification information of the transmitters provided on current four traveling wheels.
