What Is Controller Area Network?
Controller Area Network is a serial communication protocol developed by Bosch, a company based in Germany.
The controller area network communication protocol was completed in 1985. Although the communication protocol is widely used in the automotive industry, it was not adopted for mass-produced vehicles until 1990 and was subsequently defined as a standard by the International Organization for Standardization.
Controller Area Network is a technology that is widely used not only in the automotive industry but also in the factory automation (FA) area network.
Uses of the Controller Area Networks
The controller area networks communication protocol was developed for use in the automotive industry. The main application is communication between ECUs (Electronic Control Units).
Modern automobiles are electronically controlled, and each device must be able to communicate accurately at high speed. Controller Area Network communication is designed so that devices can communicate with each other without a host computer. Due to its high noise resistance, it is considered an indispensable communication protocol in the automotive industry, serving as a reliable communication technology for vehicles.
Features of Controller Area Networks
Since Controller Area Networks were developed as a communication protocol for automobile ECUs, it has a number of features of its own.
As automobiles have become more sophisticated over the years, the control details have become more complex. As the control contents become more complex, the number of inputs and outputs to ECUs increases, and the number of wirings for exchanging data between ECUs also increases. This leads to larger ECUs, more weight, more parts, and higher manufacturing costs.
To solve this problem, a high-speed and highly reliable communication technology with fewer wires is needed, and the controller area networks communication protocol was born as a result.
The controller area networks communication protocol was created with the aforementioned background and has the following features of the protocol:
- The connection between ECUs Controller Area Networks be made with fewer harnesses.
- High scalability.
- Easy communication between ECUs.
- A single piece of information Controller Area Networks is shared by multiple ECUs.
- Fault diagnosis and processing of the entire network Controller Area Networks be performed at a single location.
These outstanding features of the Controller Area Networks communication protocol have led to breakthroughs in the increasingly complex field of automotive control, and have contributed greatly to the increased functionality of automobiles around the world.
