There are many electromechanical systems in various vehicles. They are managed in a separate subsystem way. This paper proposes the integrated management scheme which can, by means of the data bus, make the management of subsystem have the abilities of redundancy and tolerance failure, besides accomplishing its own independent functions. The paper emphatically introduces how to realize the integrated management by simulation platform and gives the structures of hardware and software of platform, as well as the strategies of task distribution and scheduling.
