Study on Power Train Parameters Matching of Series Hybrid City Bus

Based on small bus YTK6605Q, this paper analyzes the performance index requirements of the power train assembly components of series hybrid city bus, and probes into the design principles and methods of the power train parameters of the series hybrid city bus, and completed the power train components´ selecting and parameter matching of YTK6605Q series hybrid city bus. ADVISOR software was used to simulate the designed prototype under certain drive cycle. The simulation result is compared with that from conventional bus prototype, from which it can be concluded that as for the newly designed prototype, the parameter selecting is reasonable and hybrid power is superior. Therefore, this paper guides theoretically the development of hybrid electric bus.
