Virtual CAN

关于

Virtual CAN creates a simulation environment to surface vehicle CAN/OBD data for Large Language Models (LLMs) and Small Language Models (SLMs). It simulates ECUs on a virtual CAN bus, decodes data using a DBC file, and exposes a suite of Model Context Protocol (MCP) tools via Server-Sent Events (SSE). This allows developers to interact with simulated vehicle data, monitor signals, decode frames, and integrate directly with LLM hosts for natural language interaction with vehicle diagnostics, all without needing physical hardware.

主要功能

• Includes a virtual CAN backend and ECU simulator for hardware-free operation
• Offers Docker support for easy deployment of the server and simulator
• Performs DBC-driven encoding and decoding of CAN messages
• Exposes CAN/OBD data and DBC metadata to LLMs/SLMs as MCP tools over SSE
• Provides a comprehensive Typer CLI for CAN frame interaction, decoding, and monitoring
• 1 GitHub stars

使用案例

• Simulating vehicle CAN and OBD-II data for development and testing without physical hardware
• Integrating vehicle diagnostic data with Large Language Models (LLMs) for natural language querying and analysis
• Developing and testing MCP-capable hosts that interact with automotive data streams
