The Vehicle Network

I’ve been doing some light reading lately about vehicle sensor systems and such, just trying to understand how it all goes together. I see a large amount of parallelism with the natural flow of computer networking.

For example, Bosch developed the concept of a Controller Area Network several years ago. In this system, wiring harnesses that carried several individual connections were replaced by a network and signalling protocol to reduce the number of wires running around the vehicle, much like the transition from star topology (mainframe) to mesh networks (Internet and Cellular).

I wonder where this will all lead. It would be nice to have the ability to replace control components as a user instead of having to take your vehicle to the mechanic, upgrading vehicle systems via your home computer, and having your car message you when a part fails.


  1. Thanks Shane! I want to develop a site that covers practical uses of technology, rather than tech for the sake of itself. The average American spends a considerable amount of time on the road and I see a special niche forming for this kind of information. I am enjoying this project immensely.
