Vehicle fuel consumption simulation model using VHDL-AMS

The vehicle system is a multi-domain system that requires many branches of science and engineering. Therefore the development of the vehicle system requires the use of design methodologies that utilize simulations, which have grown increasingly sophisticated in recent years. This paper describes how VHDL-AMS is used to model of vehicle fuel consumption simulation. This model consists of the power-train, alternator and battery system that are the basic elements of the vehicle power network system. And also, the physical quantities of the powertrain and the fuel consumption are modeled as mechanical region. Finally, the fuel consumption is shown using proposed simulation model on the Japanese 10-15 mode and JC08 mode.
