Tire Pressure Classification Database for Indirect Monitoring

Solution Overview

Problem

Indirect tire pressure monitoring systems face challenges in accurately accounting for various tire-related effects and different tire types, making them time-consuming and costly to implement reliably.

Innovation Solution

A method and system that utilize a tire classification database to determine the vehicle tire type and associate it with a classified tire type for monitoring, switching to default parameters if no association is found, allowing for efficient and cost-effective tire pressure monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If in-vehicle tests are performed to specify tire behavior for each tire type, then monitoring accuracy is improved, but time consumption and cost increase

Engineering Contradiction:

Improvetire pressure monitoring accuracyVSAvoidtime consumption for testing

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-specifying tire behavior characteristics for different tire types before actual deployment. A database stores pre-determined behavior data for various tire types, allowing the system to retrieve and apply appropriate monitoring parameters without performing time-consuming in-vehicle tests for each tire type, thus resolving the contradiction between accuracy and time consumption

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies preliminary action by pre-specifying tire behavior characteristics for different tire types before actual deployment. A database stores pre-determined behavior data for various tire types, allowing the system to retrieve and apply appropriate monitoring parameters without performing time-consuming in-vehicle tests for each tire type, thus resolving the contradiction between accuracy and time consumption

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If in-vehicle tests are performed to specify tire behavior for each tire type, then monitoring accuracy is improved, but manufacturing cost increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent applies preliminary action by pre-specifying tire behavior characteristics for different tire types before actual deployment. A database stores pre-determined behavior data for various tire types, allowing the system to retrieve and apply appropriate monitoring parameters without performing time-consuming in-vehicle tests for each tire type, thus resolving the contradiction between accuracy and time consumption

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a database that stores pre-determined tire behavior data for different tire types. Instead of performing expensive in-vehicle tests for each tire type, the system copies and retrieves appropriate behavior data from the database, significantly reducing manufacturing costs while maintaining monitoring accuracy

Inventive Principle:

Principle #26Copying

3Measurement precision

If different tire types are monitored with customized parameters, then monitoring accuracy is improved, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by creating a database that stores behavior data for multiple tire types in a standardized format. The system can handle different tire types using a single unified framework, retrieving appropriate parameters from the database rather than requiring separate customization logic for each tire type, thus reducing system complexity while maintaining accuracy

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies preliminary action by pre-specifying tire behavior characteristics for different tire types before actual deployment. A database stores pre-determined behavior data for various tire types, allowing the system to retrieve and apply appropriate monitoring parameters without performing time-consuming in-vehicle tests for each tire type, thus resolving the contradiction between accuracy and time consumption

AI summary

In indirect tire pressure monitoring of tires of a vehicle, the following steps and means to carry out the same, respectively, are contemplated: - providing a tire classification database indicating at least one classified tire type; - determining a vehicle tire type for the vehicle on the basis of vehicle data in including information on at least one tire currently used with the vehicle,- - determining whether the vehicle tire type can be associated to one of the at least one classified tire type; and - , in the case an association is determined, monitoring tire pressure according to the associated classified tire type.
