Abstract: Road tests of first sample car EQ7200HEV are carried out according to the character of hybrid electric vehicle (HEV). The experimental method is based on national standards on conventional vehicles and SAE J1711. The experiments include acceleration test of 0~100 km/h, highest-speed test, climbing capacity test, and fuel economy test based on ECE15 driving cycle. The results show that hybrid control unit (HCU) can operate powertrain logically and accurately. The fuel consumption deduces by comparison with the traditional one. The experiments also show that more improvements should be emphasized on the dynamic and economy feature. The road tests serve as references for the parameter-calibration, optimization of control strategy and the system matching. A helpful discussion about HEV’s test procedure is also undergone.
