What are Car Communication Protocols?

Let us talk about Electric vehicles here for a moment. If we were to traverse space and time to reach the past, it would be found that the very first electric vehicle was conceived even before Karl Benz’s first car. While the automobile by Karl Benz was first introduced in 1886, a person by the name of Robert Anderson created the very first electric vehicle in a rudimentary form in 1832. By the 1870s, they were even considered practical. Even though the vehicle itself was considered a wagon that was electrically powered, it certainly did catch the attention of the people at the time. So if we were to compare that vehicle with the EVs we have today, then we’ll realise that the EV produced in 1832 didn’t have many if any, subsystems to help it operate. In contrast, today’s EVs rely heavily on these subsystems to help transmit important information from one component to the other.

From the second the door to the car is opened to enter, right up to the moment the last occupant of the car leaves EV. There is an armada of subsystems that keep a constant track of information and situations around them and then receive information and orders to take actions according to the commands from the onboard brain. An example would be the interior lights turning on as soon as a door is opened or the onboard computer indicating a door that is not shut properly, sometimes even indicating which one.

When we talk about these Car Communication Protocols, there are three distinctions into which these are separated. Those are:

After that, how is it decided what protocol should be used for any new feature? Here’s how:
