• This chapter describes the basic concept and the functional principles of the controller area network (CAN) bus system along with its main features and technical advantages. CAN is a bus-oriented communication system, which is tailored for applications in automotive facilities, such as cars, trucks, buses, trains, and other vehicles. It focuses on hierarchical systems structure and the internal data exchange protocols, error detection and error handling provisions, and some additional specific features of the bus. For encoding of binary information, the NRZ (non-return-to-zero) code is used with low level for the “dominant” state and with high level for the “recessive” state. Moreover, efforts are made to depict the standard system implementations and their applications in vehicles and elsewhere in engineering. HECAN, a CAN controller integrating an Intel 82627 CAN controller and various sensors and controllers, supervised by a TMS320C40 digital signal processor is discussed in the chapter. The chapter also describes high speed and low speed CAN along with many applications of CAN.
