자동차의 시스템출력 시험방법 개발

다국어 초록 (Multilingual Abstract)

The concept of system power for motor vehicles becomes necessary because multi power sources and drivetrain are adapted in motor vehicles for the energy savings and the precise emission controls. System power is defined as the power is measured on the powertrain test bed. It is possible to measure the wheel torque precisely using the powertrain test bed due to the direct connection between absorber and the end of drivetrain without tire. Two different test methods were developed for system power measurement. One is the acceleration at full load under road load (i.e., Method Ⅰ); the other is the acceleration at full load under constant vehicle speed (i.e., Method Ⅱ). Test vehicles were ICEV, HEV, FCEV, and EV. The drivetrains for the vehicles were AT, CVT, and reduction gear respectively. It was found that ICEV had the lowest maximum system power by the method I due to the efficiency of the drivetrain. The other vehicles were similar results of the maximum system power for two different test methods. Therefore, it could be adopted these two methods for the measurement of system power in motor vehicles.
