External Tire Wear Probability Calculation via Wireless Data Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle owners and dealers lack an effective way to determine the wear condition and type of tires on a vehicle, leading to uncertainty about when new tires are needed.
Innovation Solution
A method and apparatus that utilize a vehicle memory unit to store tire data, which are transmitted externally for determining tire wear probability, allowing for centralized calculation and wireless radio link transmission, enabling reliable determination of tire wear and type, and automatic signaling for new tire needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If tire data are stored only in the vehicle memory unit, then data availability is limited to the vehicle, but data cannot be accessed or processed externally to determine tire wear probability
Solution Approach 1:
The patent extracts tire data from the vehicle memory unit and transmits it to an external server. The server then processes this data to determine tire wear probability, replacing the need for complex in-vehicle processing systems while maintaining data accessibility externally.
Solution Approach 2:
The patent introduces a server as an intermediary between the vehicle memory unit and the tire wear determination system. The server receives tire data, processes it to calculate wear probability, and returns results, simplifying the overall system architecture while enabling external data processing.
2Reliability
If tire wear probability is determined on the vehicle, then reliability is improved due to access to current tire data, but device complexity and cost increase
Solution Approach 1:
The patent extracts the complex processing function from the vehicle and relocates it to an external server. The vehicle only needs to transmit data, while the server performs the wear probability calculation, reducing in-vehicle complexity while maintaining determination accuracy.
Solution Approach 2:
The server automatically receives tire data, processes it to determine wear probability, and generates results without requiring complex in-vehicle processing equipment. This self-service approach simplifies the vehicle system while maintaining reliable tire wear assessment.
3Productivity
If tire data are transmitted wirelessly to external memory unit, then data processing can be centralized and costs reduced, but transmission reliability may be affected by radio link issues
Solution Approach 1:
The patent uses a wireless radio link as an intermediary for data transmission between the vehicle and server. The radio transmission unit sends tire data externally, enabling centralized processing while accepting the inherent limitations of wireless communication.
Solution Approach 2:
The system transmits tire data externally as soon as it becomes available in the vehicle memory unit, preparing the data for centralized processing in advance. This preliminary data transmission enables efficient batch processing at the server while maintaining data freshness.
Data Source
AI summary
In a method for making available data relating to the tires of a vehicle, vehicle data and/or tire data is made available by a vehicle memory unit of the vehicle, wherein the vehicle data is acquired by a sensor which is arranged in the vehicle. The vehicle data and/or the tire data have information on at least one property of the tires of the vehicle. A tire-wear probability of the tires of the vehicle is acquired as a function of the vehicle data and/or tire data. The tire-wear probability and/or the vehicle data and/or tire data are stored permanently in a memory unit arranged externally with respect to the vehicle and are made available for determining whether the vehicle requires new tires.
