摘　　要：为了加快某新型混动力汽车控制系统开发、降低成本,利用基于Matlab/Simulink平台的多领域物理系统建模工具SimPowerSystems和SimDrivelines建立其动力驱动系统及传动系统的仿真模型。在此基础上,提出了纯电动至发动机驱动、发动机驱动至联合驱动典型模式切换过程的控制策略,并对这两种模式切换过程控制策略的性能进行仿真分析。仿真结果表明所设计的模式切换控制策略可以保证模式切换过程动力传递的平稳性,所建立的混合动力汽车多领域物理系统模型的合理性和可行性,为混合动力汽车建模与控制仿真提供一条快捷而有效的新途径。In order to accelerate a new hybrid electric vehicle control system development and reduce cost, the power drive system and transmission system are established by SimPowerSystems and SimDrivelines on Matlab/Simulink platform. And the mode switching control strategy for pure electric mode to engine drive mode and engine drive mode to hybrid drive mode process were proposed, and the performance of the two mode switching control strategy was simulated. The simulation result indicates that the designed control strategy ensures smooth power transfer during mode switching process. The multi-domain physical modeling of hybrid electric vehicle is reasonable and feasible, which will provide a new and efficient method for modeling and control of hybrid electric vehicle.
