1)Composition and Main Hardware of CAN

The fundamental CAN-BUS system(as shown in Fig.2.2)includes one CAN controller,one information receiver,two data transfer terminal and two data transfer bus,and except the data transfer bus,other components should be inside each control unit.

Data transfer terminal-terminal resistance:there are two terminal resistances on both ends of data bus,usually in the ECU and IPC,to prevent the data from being reflected at the terminal and returning in the form of echo,because reflection of data at the terminal will affect the data transfer.(https://www.daowen.com)
