Algorithms and Software for Development of Modular Vehicle Architectures

Modular systems provide the ability to achieve product variety through the combination and standardization of components. The trend within the automotive industry is towards modular systems. The automotive manufacturers separate the vehicle into modular systems (chunks), which may be built and tested off line before assembled for vehicle installation. In this paper, software that utilizes a new clustering algorithm for development of integrated and modular vehicle architectures is presented. The algorithm and software tool presented in this paper allows the system designer to automate and optimize the vehicle system development process. A vehicle system model that identifies all the functional (data, and control) interfaces between vehicle system functions is the input to the software tool. The software tool is capable of analyzing this input data and determining the vehicle system architecture by optimally grouping (integrating) functions into physical modules. If the system designer feels that further integration of the vehicle system architecture is necessary then the software is capable of further integrating or separating the system functions to satisfy the vehicle development constraints.
