Abstract
Over the years, there is increasing demand for development of technologies to achieve CO2 emissions and fuel economy regulations in automobile industries. There are two types of automatic transmission, Step AT and CVT, and many manufacturers are utilizing CVT in order to improve fuel economy and drivability both. Improvement of fuel economy can be achieved by driving engine on optimal operating line, due to CVT's continuously variable ratio. Increasing demand for better fuel economy and smoother shift quality leads to increment of required functions, processes and verifications. On the other hand, project terms are getting shorter and shorter. It is necessary to find proper system configuration at early design stage. In this stage, the design should be made without 3D geometrical data. 1D-CAE is considered one of the most promising solutions to be used. It is a simulation methodology which calculates system behavior using one directional lumped-parameter system models. AMESim and MATLAB are examples of modeling and simulation tool of 1D-CAE model. This paper introduces seamless development concept, specific example and possibility of CVT system development using 1D-CAE plant model. In addition, to consider the effect of education for engineers in the enterprise using the 1D-CAE model.
