based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...

The increased interest in model-based control techniques for the energy management of hybrid electric vehicles has led to a focus on generic modeling in order to allow an effective integration in model-based design procedures. An architecture-free model ensures modularity with a view to control design. Under mild assumptions, a generic model for the torque and the rotational speed of a hybrid e...

This paper studies the impact of fuel-cell (FC) performance and control strategies on the benefits of hybridization. One of the main weak points of the FC is slow dynamics dominated by a temperature and fuel-delivery system. Although many researchers have investigated the use of different powertrain topologies, component sizes, and control strategies in fuel cell vehicles, a detailed parametric...

The increasing automobile vehicles and congestions in the world cause critical pollutions such as air and noise. Hence, we need comprehensive measures to reduce carbon dioxide (CO2) emission in transportation area. Many researchers have studied the impact of adopting ecofriendly vehicles such as electric vehicle (EV), hybrid electric vehicle (HEV), plug-in hybrid electric vehicle (PHEV), and fu...

Automobiles have an influence on the global environment that cannot be disregarded, not only through air pollution in cities but also through large carbon dioxide emission that leads to global warming. A hybrid electric vehicle combining a gasoline engine and an electric motor has proved to be an effective means to solve these problems. Electrical energy flow of the vehicle is controlled with i...

A new hybrid-drive system taking flywheel energy storage system instead of chemical battery as assistant power source for hybrid electric vehicle is put forward. According to the particular energy characteristics of flywheel system, an energy management strategy based on fuzzy logic control is also developed with overall consideration on the optimization of both ICE (Internal Combustion Engine)...
