Paper Abstract

General Motors Powertrain Group (GMPTG) has been the leader in implementing open, modular architecture controller (OMAC) technologies in its manufacturing applications since 1986. The interest in OMAC has been greatly expanded for the past two years because of the advancement of personal computer technologies and the publishing of the OMAC whitepaper by the US automotive companies stating the requirements of OMAC technologies in automotive applications. The purpose of this paper is to describe the current OMAC projects and the future direction of implementation at GMPTG. An overview of the OMAC project and the definition of the OMAC concept are described first. The rationale of pursuing open technologies is explained from the perspective of GMPTG in lieu of its agile manufacturing strategy. Examples of existing PC-based control applications are listed to demonstrate the extensive commitment to PC-based technologies that has already been put in place. A migration plan form PC-based to OMAC-based systems with the thorough approach of validation are presented next to convey the direction that GMPTG is taking in implementing OMAC technologies. Leveraged technology development projects are described to illustrate the philosophy and approaches toward the development of OMAC technologies at GMPTG. Finally, certain implementation issues are discussed to emphasize efforts that are still required to have successful implementations of OMAC systems.
