Research on modeling, simulation and control of new type power split hybrid powertrain

Abstract

In order to satisfy the growing demand of vehicle new energy and energy-saving technologies, much concepts have emerged, including electric driving, hybrid powertrain and fuel cell electric vehicle, etc. This study targets a new type of hydraulic hybrid powertrain of a series-parallel structure. The look-forward simulation method is used to establish dynamic mathematical model of the provided hybrid powertrain. Based stop-and-go duty cycle, the economy of vehicle with hybrid powertrain is studied based on the dynamic simulation model.
