Modern vehicles are essentially mobile computers and controller networks. On average, there are around ten embedded controllers in a vehicle. These controllers are responsible for running the engine, locking and unlocking the vehicle, sounding the horn, and much, much more. These networks are very different from current computer networks. This talk will help you understand how to get started, what information is on the vehicle network, and how you can use this data to get information from and send commands to these controllers. Additionally, this talk will list the current tools available for communicating with vehicles and how to interpret the communications between the controllers.
