While researching the topic of car networking I realized that there is no decent illustration for how vehicle bus protocols are related to ISO/OSI model. Though for each protocol this relation to ISO/OSI can be found in official ISO specification I haven’t seen a picture of all most popular protocols depicted in one place.

I’ve included OBD in UDS because UDS seems to extend OBD, in a manner of speaking. Also, I haven’t included protocols for trucks and industrial machines because they are currently out of scope of my research.
