Abstract
Dynamic system simulation is important for automotive development and improvement as well as for analyzing mechanism of the system. A vehicle power train with a continuously variable transmission (CVT) was modeled into a simple and a detailed Bond Graph model and the fuel economy and engine power performance was simulated by use of the models according to the Japanese 10 Mode cycle. As a result, it is verified that the proposed Bond Graph models represent the basic dynamic characteristics of vehicle power train system with CVT and it is useful to calculate the optimum gear change pattern for low fuel consumption.
