Abstract: “This paper provides an overview of the most commonly used traditional networks and new generation in-vehicle networks. Comparison and Usage and trends of in-vehicle networking protocols will be presented and categorized. The past few years have seen a large growth in the number and type of communication buses used in automobiles, trucks, construction equipment, and military, among others. Development continues even into boating and recreation vehicles. Areas for discussion will include SAE Class A, B, C, D. It is believed that the comparison presented in this paper would benefit application engineers in selecting an appropriate protocol.”
