In this study, an engine on/off and engine operation control algorithm to improve the fuel economy was proposed for a PHEV(plug-in hybrid electric vehicle) considering driver tendency. To identify the driver tendency, a driver model was developed using VIDE(virtual integrated development environment). The target vehicle model was developed based on MATLAB/Simulink and validation of the vehicle model...
In a range-extended electric vehicle (RE-EV), the system efficiency decreases when the engine power is transmitted to the driving motor through the battery due to the charging and discharging energy conversion efficiency. To improve the system efficiency, a control algorithm is proposed using the route information. The control algorithm calculates the threshold power based on the battery charging...
In this study, component design of x-EVs was performed using virtual integrated development environment (VIDE). First, component library was developed for various components such as the engine, motor, battery and transmission. Vehicle performance simulator of x-EVs was developed using MATALB SimDriveline, which consists of the powertrain system and control system. Experiment and commercial software...
A battery charging control using a driving motor is proposed for an AT based parallel HEV. To charge the battery using the driving motor, a 2-clutch system control is proposed which uses the engine clutch and the clutch inside the transmission. The battery charging efficiency is estimated from the engine fuel consumption and efficiency of the power electronics. To evaluate the performance of the suggested...
