CAN is a serial communication protocol first developed by Robert Bosch Company in 1983 and officially recognized in 1986 by the Society of Automotive Engineers (SAE). In 1991, Bosch issued CAN 2.0 version and two years later became ISO 11898. Currently, almost all cars use CAN standard to communicate between controllers. Some advantages can be summarized when a system uses CAN as follows:
Compact and more economical than common standards. CAN is a 2-wire transmission standard, requiring no synchronization pulse to transmit information.
Suitable for applications that require real time. The CAN network has an ID-based arbitration system that makes instantaneous transmission of high priority messages.
Increase the security level of the system. The failure of one module in the CAN network does not affect the remaining modules, unless the two modules are directly related to each other and cannot function without the other. At the same time, adding / removing modules in the system can be done as soon as the system is working without any problems for the electrical system.
The feature of CAN is the method of addressing and object-oriented communication, while most other communication systems rely on station addresses. Each information exchanged in the network is treated as an object and is assigned an ID code. Information is sent on a bus that transmits messages in different lengths. The content of each notification is distinguished by stations that are issued with the ID. The ID does not indicate the destination of the notice, but only the meaning of the message. Therefore, each station on the network can decide whether to receive and process messages or not to receive notifications through notification filtering method, so that many stations can receive many notifications at the same time and have other responses together.
