ProtoPie

Car HMI — AI-Powered Vehicle Diagnostics

Built an in-vehicle HMI concept that goes beyond static warning lights — live vehicle data (tire pressure, coolant, battery) feeds directly into GPT-4o, which diagnoses issues and explains them to the driver in plain, conversational language. Built with ProtoPie Connect and demoed live at IAA Mobility 2025 in Munich.

Process

  1. Concept

    From static warning lights to conversational diagnostics

    • Built a car dashboard prototype displaying real-time metrics for tire pressure, coolant levels, and battery status, driven from a separate controller device.
    • Connected the dashboard to GPT-4o via ProtoPie Connect — when a metric moves into a problem range, the live data is sent to the AI for diagnosis.
    • Designed the AI's response to be conversational rather than a generic alert: it explains what's wrong and suggests a specific next step, optionally read aloud via text-to-speech.
    • Configured two parallel ChatGPT API connections in ProtoPie Connect so the dashboard could request and receive diagnoses without blocking the interaction.

Outcomes

  • Demoed live at IAA Mobility 2025 in Munich — one of the world's largest mobility trade shows.
  • Showed how ProtoPie can validate AI-driven automotive features using realistic, dynamic data rather than scripted demos.
  • Established a reusable pattern — live sensor data into an LLM, paired with a conversational UI layer — for prototyping proactive vehicle assistant concepts.
