英文摘要： In the power transfer process of the dual-planetary gear hybrid electric vehicle (HEV), there are coordinations and matching problems of multiple power sources and the energy management system design has become the core of the related researches. In this program, taking the hybrid dynamic characteristics in the energy management system of the dual-planetary gear HEV into consideration, the energy management problems will be transformed into some certain scientific problems, such as the dynamic modeling and optimal control of a determined hybrid system.Based on the operating mode extraction of the powertrain system and the inner loop power analysis of the gear set, the structural parameters of the power coupling device will be optimized. Then an in-depth study on the hybrid dynamic behaviors of this energy management system will be carried out. Based on the above analysis, the coupling mechanism and rules between the continuous dynamic process and the discrete event, which are closely related and interacted with each other, will be disclosed. Then, a mixed logical dynamical system model will be established based on the hybrid system theory and an effective control system will be designed based on the model predictive control technology. Subsequently, the explicit expressions of the hybrid model predictive control laws will be achieved by means of multi-parametric programming techniques. Finally, the hardware-in-loop simulations and bench tests will be carried out to verify the actual performance of the control system. In a nutshell, for the dual-planetary gear HEV, this research can accurately grasp the hybrid nature of the system. At the same time, it will improve the fuel economy and guarantee the switching quality by the optimal control based on the hybrid system theory. The research will realize efficient energy management and provide the new theoretical basis and technical support for the analysis and design of the energy management system for dual-planetary gear HEV.
