With the development of data bus technology and the increasing demand for low-cost and high-reliability electrical systems in "flight-based transportation", Field Bus(FB) is gradually favored by the aerospace field. Controller Area Network(CAN), one of the most widely used field buses, has been researched and applied in missiles and tactical rockets. Considering the differences between launch vehicles and missiles, the application of CAN bus in launch vehicle control systems is expounded. The necessity of research is firstly analyzed, then typical CAN topologies suitable for medium and large-scale launch vehicles are given respectively. For the aim of practical use, two corresponding technologies are introduced which are the CAN relay technology and the CAN bus reconstruction. The efficiency and load rate of CAN bus are calculated which are then compared with the ones derived by 1553B data transmission under the same conditions. These results can be referenced by designers in a more accurate sense.
