An experimental open-source application that integrates GPT-3.5-turbo (or GPT-4), NLP, TTS, STT, and an OBD-II ELM327 device to create a voice-activated, hands-free, vehicle diagnostic assistant.

⚠️ This is a work in progress ⚠️

🔜 ElevenLabs TTS, Google Calendar integration coming soon.

• Windows 11
• Python 3.11.3
• OBDlink MX+ Bluetooth ELM327
• 2005 and 2021 Ford Vehicles
• Desktop testing using an ELM327 emulator

1. Clone the repository:

git clone https://github.com/Explorergt92/Automotive-AI.git

2. Run the following command in the root directory:

./install.sh

.\install.bat

3. Set your API keys and variables in the .env.template file and save it as .env without a file extension.

Without a vehicle communication interface:

python main.py

With an ELM327 device connected:

python main.py --device elm327

Current voice commands include:

• "engine rpm": "010C",
• "intake air temperature"
• "fuel tank level"
• "time run with MIL on"
• "engine coolant temperature"
• "read trouble codes"
• "freeze frame data"
• "pending trouble codes"
• "clear trouble codes"
• "vehicle identification number"
• "calibration id message count"
• "calibration id"
• "calibration verification numbers"
• "start a diagnostic report"
• "send a diagnostic report"
• "next on outlook calendar"
• "create a new outlook appointment"
• "check outlook"
• "send an email with outlook"
• "ask question"
• "start conversation"
• "check gmail"
• "what's next on my google calendar"

After a conversation has been started you can use the following voice commands to manage the conversation:

• "clear all history"
• "delete the last message"
• "end the conversation"
• "summarize the conversation history"

ELM327 emulator: GitHub com0com virtual serial port driver: SourceForge (to create a virtual COM port pair).

After installing com0com, run:

elm -p COM6 -a 500000

Set the COM port in the .env file to COM7.

python air_fuel_datastream.py

Streams data from the OBD-II ELM327 device to the console, but there's currently no way to stop the stream other than closing the application.
