Controller Area Network or CAN

Controller Area Network, which also is recognized with CAN as well as with CAN-bus abbreviations, is normally known as standard named as vehicle bus standard. This standard is normally designed in intention of allowing devices as well as microcontrollers to make communications freely with one and other without having installed or configured a host computer within the area of a bus.


Controller Area Network or you may say CAN-bus or simply CAN, is actually known as a protocol that falls under the message based protocols’ category which is specifically designed to be used only within the automotive applications. But this type of vehicle bus standard is also widely being used in some other areas in which the area of medical equipment as well as the area of industrial automation is also included.

Originally the developed of this in-discussion CAN-bus or simply CAN or you may say Controller Area Network had been started at the notorious Robert Bosch GmbH back in year 1983. But the official release of this vehicle bus standard was made at the Society of Automotive Engineers or you may say SAE’s congress in Michigan’s Detroit area in year 1986.

Intel as well as Philips became the first introducer as well as the producer of the first chips of Controller Area Network or you may say CAN controller which was marketed in year 1987. The specifications of CAN 2.0 were published by Bosch in year 1991. Notorious diagnostics standard of the vehicle bus standard known as OBD-II is recognized being the one of those five protocols that uses this in-discussion standard.


The above mentioned standard of OBD has been installed as a compulsory or mandatory standard in the United States in all light trucks as well as in all cars since year 1996 and all the petrol vehicles are carrying EOBD standard installed being a compulsory or mandatory standard since year 2001 in Europe.
