군용 하이브리드 추진시스템 회생제동장치 연비개선 평가

Regenerative brake system in currently developing lightweight tactical HEV can"t absorb maximum regenerative power because of braking feeling. In this study, we didn"t activate frictional brake until regenerative brake absorbs maximum torque by making additional devices and setting them to the vehicle. And we performed the fuel economy test on the vehicle 4X4 TM dynamometer. The result shows that 53% energy absorption increase in brake-stop test, 8.7% fuel economy increase in FTP-72 mode and 10.8% increase in South Korean forward area driving mode.
