摘要：
The torsional vibration of hybrid vehicle powertrain system not only relates to the safety of the vehicle, but also affects passenger comfort. Aiming at the demand for simulation modeling in torsional vibration research, a method is proposed to recognize the dynamic parameters and to correct engine torque fluctuation. First, dynamic models and their applicability of the main components in the powertrain system are briefly introduced. The focus is put on the constitution and characteristics of engine torques calculated by a single-cylinder engine model, and a theoretical formula is given for correction. Then, possible acquisition methods and credibility of the obtained dynamic parameters of the system are reviewed. Taking advantage of the characteristics of a hybrid power system, a method with implementation steps is proposed to identify these parameters by combining experiments and simulation. Finally, a series-parallel powertrain for city bus is taken as an example, where the applicability of the proposed method and the simulation model are verified by means of bench tests under the typical working conditions. © 2019, Tsinghua University Press.
