Modern cars are networks of computers, and a high end vehicle could have nearly 100 different computers inside. These devices control everything from the engine to the airbags. By understanding how these systems work, we can interface with vehicles to read data, perform diagnostics, and even modify operation.
In this talk, we'll discuss pyvit, the Python Vehicle Interface Toolkit. This library, combined with some open source hardware, allows developers to talk to automotive controllers from Python.
We will begin with an introduction to automotive networks, to provide a basis for understanding the tools. Next, we will look at the tools and show the basics of using them. Finally, we'll discuss real world applications of these tools, and how they're being used in the automotive world today.
