AI-Powered Vehicle Diagnostics: Trends, Gaps, and Opportunities

  • Abstract:
  • Traditional vehicle diagnostic methods rely on onboard diagnostics (OBD) that produce cryptic error codes, requiring expert interpretation. Furthermore, non- expert vehicle owners struggle to accurately describe symptoms, leading to diagnostic ambiguity and delays. This paper presents an AI-driven vehicle diagnostic system that leverages a transformer-based Natural Language Processing (NLP) model to interpret user-submitted, free- text descriptions of vehicle issues. The system processes natural language inputs to identify the probable fault part and recommend a corresponding repair solution. By training a BERT/DistilBERT model on a historical fault dataset, our framework automates the initial diagnostic process. The architecture features a web/mobile interface for user interaction, an AI core for inference, and a backend for data storage and trend visualization. Performance evaluation on a test dataset indicates a high F1-score for fault classification, demonstrating the viability of using advanced NLP to make vehicle diagnostics more accessible and efficient.
