- Driving Strength Analysis Using 1D System Model and Application in Power Unit Development -

Abstract

For highly efficient power unit development, it is important to construct a detailed 1D system model and predict vehicle performance in the performance design phase, considering market usage conditions. Market load forecasting technology using market data, which has been increasingly utilized in the automotive industry in recent years, is indispensable for highly accurate performance prediction. In this study, we developed a simulation technology that can analyze market driving strength by using a 1D system model and market data. Furthermore, we describe how the representative data extracted from the driving strength analysis results can be used to predict vehicle performance.
