NLP Vehicle Diagnostics Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automotive scan tools, despite their advanced functionality, are often difficult for non-professionals to use effectively, leading to underutilization of their capabilities and unnecessary professional servicing, as they require technical expertise and specific knowledge of vehicle terminology.
Innovation Solution
A system utilizing natural language processing (NLP) to interpret user commands and derive relevant scan tool functions, allowing users to interact with a mobile app or device connected to a vehicle's OBD port, enabling the selection and execution of diagnostic functions without needing to know how to operate the scan tool or understand technical terminology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If scan tools are equipped with advanced functionality and comprehensive diagnostic features, then diagnostic capability and productivity are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent introduces an intermediary layer between the user and the scan tool's complex diagnostic functions. This intermediary processes natural language user inputs, translates them into appropriate diagnostic commands, and presents results in an understandable format. The intermediary effectively bridges the gap between simple user interaction and complex diagnostic capabilities without exposing users to the underlying complexity.
2Productivity
If scan tools are equipped with advanced functionality and comprehensive diagnostic features, then diagnostic capability and productivity are improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the traditional mechanical interface of scan tools (physical buttons, menus, and technical操作流程) with a natural language processing system. Users can interact with the diagnostic system using everyday language instead of navigating complex technical interfaces. This substitution maintains full diagnostic functionality while dramatically improving ease of operation for non-expert users.
3Ease of operation
If scan tools are simplified for ease of use by non-professionals, then ease of operation is improved, but diagnostic capability and functionality are reduced
Solution Approach 1:
The patent creates a universal interface that can handle any diagnostic function through natural language commands. The system is designed to be multi-functional, accommodating everything from basic vehicle information queries to complex diagnostic procedures. The natural language interface adapts to various user needs and vehicle types, providing comprehensive diagnostic capability while maintaining simplicity for all users.
Data Source
AI summary
A method of providing vehicle diagnostics may include receiving a first communication from a user, processing the first communication using a natural language processing (NLP) model to produce NLP model output including a sequence of words, extracting one or more keywords from the sequence of words, and instructing a data acquisition and transfer device (DAT) connected to an OBD port of a vehicle to perform a selected function based on the one or more keywords. The method may further include receiving diagnostic data from the DAT, the diagnostic data having been retrieved from the vehicle by the DAT in accordance with the selected function, and determining a diagnostic condition of the vehicle based on the diagnostic data.
