Tire Module Data Transfer via Ultra-Narrowband Parking Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems face challenges in easily and cost-effectively transferring measurement data from tire modules to a fleet operator's database.
Innovation Solution
A method involving tire modules with a transmitting unit using an ultra-narrowband frequency band to transmit data to an external receiving unit at designated transmission stations, activated upon vehicle parking, which forwards data to an external database via the Internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission uses a licensed frequency band, then transmission reliability is improved, but transmission cost increases
Solution Approach 1:
The patent changes the frequency parameter from licensed bands to ultra-narrowband license-free bands (862-928 MHz), transforming the transmission approach to achieve cost-effectiveness while maintaining reliability through alternative means such as external receiving units at transmission stations
2Loss of information
If continuous transmission is implemented, then data availability is improved, but energy consumption increases
Solution Approach 1:
The transmitting unit is activated periodically based on driving time and parking duration conditions rather than continuously operating, creating an intermittent transmission pattern that reduces energy consumption while ensuring data is transmitted when the vehicle is stationary at transmission stations
Solution Approach 2:
The system automatically determines when to transmit based on built-in sensors detecting parking duration and driving time, with the control algorithm autonomously deciding activation without external intervention, optimizing the balance between data availability and energy usage
3Reliability
If transmission stations are densely distributed, then network coverage is improved, but system complexity increases
Solution Approach 1:
External receiving units are positioned as intermediaries at transmission stations, acting as relay points that collect data from multiple vehicles and forward to the central database, reducing the need for direct vehicle-to-cloud connections and simplifying the overall system architecture
Solution Approach 2:
The external receiving units at transmission stations serve multiple functions: receiving data from tire modules, validating transmission conditions, buffering data temporarily, and forwarding to the database, making the transmission station infrastructure multi-functional and reducing the need for dedicated simple receivers

AI summary
A method comprising the following steps is proposed: a) providing a vehicle (1) with at least one vehicle tire (2) with a tire module (3), wherein the tire module (3) comprises a pressure sensor for detecting tire pressure and a transmitter unit for transmitting data, the transmitter unit using a license-free frequency band in an ultra-narrowband range for transmission; b) activating the transmitter unit from the tire module (3) when the vehicle stops at a transmission station for a predetermined parking time after a predetermined driving time; c) transmitting the data from the tire module (3) to an external receiver unit (4) located outside the vehicle (1) and in the vicinity of the transmission station, the transmission using the frequency band in the ultra-narrowband range; d) forwarding the data to a software system on the Internet.
