Vehicle Tire Abrasion Mapping for Real-Time Pollution Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air quality monitoring systems fail to provide comprehensive information on pollution generated by vehicle tire abrasion, particularly smaller particles, which are not captured by local measurement stations, leading to gaps in air quality data.
Innovation Solution
A method and system that utilizes vehicle sensors to collect tire abrasion data, generate a hypermap of pollution levels, and provide real-time information to vehicles for controlling cabin air systems, navigation, and pollution control systems, using friction coefficients and weather conditions to estimate tire-generated pollution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If local measurement stations are used to monitor air pollution, then information about current pollution status can be provided, but smaller particles caused by vehicle tire abrasion cannot be detected
Solution Approach 1:
The patent introduces an intermediary system consisting of vehicle-mounted sensors that detect tire abrasion particles and transmit this data to a central server. This intermediary bridges the gap between traditional measurement stations that cannot detect small particles and the need for comprehensive pollution monitoring, allowing tire abrasion particle information to be collected and made available to vehicles.
Solution Approach 2:
The patent replaces the mechanical/physical measurement station infrastructure with an electronic sensor-based system mounted on vehicles. Instead of relying on fixed measurement stations with limited detection capabilities, the system uses electronic sensors on moving vehicles to detect and report tire abrasion particles, substituting a static mechanical system with a dynamic electronic one.
2Reliability
If comprehensive tire abrasion monitoring is implemented across multiple vehicles, then accurate pollution data can be provided, but system complexity and data processing requirements increase
Solution Approach 1:
The patent segments the pollution monitoring system into independent vehicle-mounted sensor units, each collecting local tire abrasion data. Instead of a centralized complex monitoring system, each vehicle independently measures and transmits its own data to a server, dividing the overall system into simple, autonomous segments that collectively provide comprehensive coverage.
Solution Approach 2:
Each vehicle in the system serves itself by autonomously measuring its own tire abrasion particles and transmitting this data to the central server. The vehicles self-generate the pollution data without requiring external monitoring infrastructure, reducing the complexity of the overall system while improving data reliability through distributed measurement.
