Because of high oil prices and emission gas problems, many governments tighten regulation of fuel economy and emission gas. For passenger car, there are many researches for plug-in hybrid electric vehicles and they are being manufactured. On the other hand, there are few researches for plug-in hybrid electric bus that is heavy commercial vehicle. In this study, components sizing of E-REV bus is conducted considering target vehicle performance and AER. Based on results of components sizing, forward simulator is developed for analysis of E-REV bus using Autonomie.

This paper describes control algorithm and control structure of vehicle control unit for range-extended electric vehicle equipped with engine-generator system, and specially presents methods which determine optimal operating points and decreases a vibration or a shock for operating the engine-generating system. The vehicle control algorithm is consisted of several parts which are sequence control, calculation of wheel demand torque, determination of operating points, and management of operating points and so vehicle controller has be made possible to efficiently manage calibration parameters. The control algorithm is evaluated by driving test modes, launching performance and operating engine-generator system and so on. In conclusion, this paper present methods for extending a mileage, improving a launching performance and reducing vibration or shock when the engine-generating system is starting or is stopping.

It is very important to determine specifications of components included in the drive-train of vehicles at the initial design stage. In this study, component sizing process and performance analysis for Extended-Range Electric Vehicles (E-REV) are discussed based on the foundation of determined system configuration and performance target. This process shows sizing results of an electric driving motor, a final drive gear ratio and a battery capacity for target performance including All Electric Range (AER) limit. For E-REV driving mode, the constant output power of a Gen-set (Engine+Generator) is analyzed in order to sustain State of Charge (SOC) of the battery system.

To prevent global warming in the automotive section, European EPA have chosen to limit CO₂ emission while the USA have chosen fuel consumption and the limit has been tightening every year. Eco-friendly car is no longer an option for automotive companies, it is vital for them to jump over the emerging environmental trade barrier. This report will introduce various types of electrification powertrain and driven type then assess the customer"s acceptability of each platform. With this result we may set up the company"s direction of electric vehicle development and possibility for commonizing between electric vehicle platform and conventional ICE vehicle platform.

In this study, a route information based control algorithm was developed for range-extended electric vehicle (RE-EV). The algorithm estimates demanded vehicle power and SOC charging amount using the route information and vehicle dynamic model. In addition, a threshold vehicle demanded power was obtained to improve the energy conversion efficiency by transmitting the power from the range extender to the driving motor directly. To evaluate the performance of the algorithm, a RE-EV performance simulator was developed. It was found that fuel consumption can be reduced compared with the existing control algorithm by the proposed algorithm .
