The application of controller area network on vehicle

In order to use less lines to realize data communication between test devices, microprocessors, sensors and actuators and to accelerate the development of the computerization of vehicles, BOSCH developed a controller area network (CAN) in the early 1980s. Because of its many advantages, a CAN bus is to be adopted in electric equipment which is being researched at present or will be researched in the future. In a sense, the CAN bus begins a new era of electric equipment of vehicles. This paper introduces some advanced characteristics of CAN and makes a comparison between CAN and BITBUS presented by INTEL. The application of CAN on a vehicle is proved by three examples.
