In-vehicle networking has created a revolution in automotive technology over the past two decades. A vehicle network consists of components like the transport medium, transceivers, microcontrollers, and a network protocol that allow different systems in a vehicle to communicate as a single entity. There are various bus system classifications like Class A-D based on factors such as data transfer rate, interference immunity, and number of network nodes. Popular network topologies include compact and luxury vehicle classes with centralized CAN bus systems, which were developed by Bosch in 1986 and provide low-cost, robust, and flexible communication between components.
