An Approach on Modeling for Functional Development of Automobile

An approach of modeling is put forward for automobile product development, and a concept of a functional model is proposed in this paper. Functional models of mechanical, electrical and fluid systems of single degree of freedom are introduced. A wiper system and a power train system are modeled using this approach, and hierarchical functional models of these systems are presented. Simulation result with the hierarchical functional model is compared with test result using an actual power train system of passenger car in order to verify validity and usefulness of the proposed approach.
