Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for acquiring vehicle information using on-board diagnostics (OBD) are difficult to use with evolving vehicle architectures, limiting data generation capabilities.
Innovation Solution
A method and system that utilize an infotainment system's user interface to present menus for selecting vehicle information from electronic control units, generate a code embedding the information, and display it, allowing for efficient acquisition and retrieval across multiple vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If OBD methods are used to acquire vehicle information, then vehicle data can be accessed, but the process is difficult to use with evolving vehicle architectures and limits data generation capabilities
Solution Approach 1:
The system provides a universal interface that can work across different vehicle architectures and ECU types. The menu-driven approach and code generation mechanism are designed to be architecture-agnostic, allowing the same system to extract information from various ECU implementations without requiring architecture-specific customization.
Solution Approach 2:
The patent introduces an intermediary code generation mechanism that acts as a mediator between the ECU memory and the user/external systems. Instead of directly accessing ECU memory through architecture-specific OBD protocols, the system generates standardized codes (such as QR codes or barcodes) that encapsulate the vehicle information, making it universally accessible regardless of the underlying vehicle architecture.
2Productivity
If individual connection and waiting is required for each vehicle, then vehicle information can be acquired accurately, but data acquisition efficiency is reduced
Solution Approach 1:
The system performs preliminary actions by generating the information code directly within the ECU memory or infotainment system before any external access is needed. This preliminary code generation eliminates the need for sequential connection and waiting, as all necessary information is pre-packaged in the code that can be rapidly scanned and captured from multiple vehicles simultaneously.
Solution Approach 2:
The patent creates a copy of the vehicle information in the form of a standardized code that can be rapidly transmitted and captured. Instead of maintaining continuous connections to extract data from each vehicle, the system creates information copies (codes) that can be quickly scanned, stored, and processed, dramatically improving throughput when dealing with multiple vehicles.
Data Source
AI summary
A method for acquiring vehicle information. A menu is presented in a user interface of an infotainment system of a vehicle for acquiring vehicle information. Vehicle information is selected via the menu to obtain from memory associated with at least one electronic control unit. Vehicle information obtained based on the selecting of the vehicle information via the menu is received. A code is generated having the vehicle information embedded therein. The code having the vehicle information embedded therein is displayed.
