To avoid unnecessary power loss during switching between the various power sources of a composite electric vehicle while achieving smooth operation, this study focuses on the development and dynamic simulation analysis of a control system for the power of a parallel composite vehicle. This system includes a power integration and distribution mechanism, which enables the two power sources of the internal combustion engine and electric motor to operate independently or in coordination to meet the different power-output requirements. The integration of the electric motor and battery-charging engine reduces the system complexity. To verify the working efficiency of the energy control strategy for the power system, the NEDC2000 cycle is used for the vehicle driving test, a fuzzy logic controller is established using Matlab/Simulink, and the speed and torque analysis of the components related to power system performance are conducted. Through a dynamic simulation, it is revealed that this fuzzy logic controller can adjust the two power sources (the motor and internal combustion engine) appropriately. The internal combustion engine can be maintained in the optimal operating region with low, medium, and high driving speeds.

新型并联混合动力系统的动态仿真与控制

为了在实现平稳运行的同时避免在复合电动汽车的各种电源之间切换期间造成不必要的功率损耗，本研究着重于并联复合汽车动力控制系统的开发和动态仿真分析。该系统包括功率集成和分配机制，该机制使内燃机和电动机的两个动力源能够独立运行或协调运行，以满足不同的动力输出要求。电动机和电池充电引擎的集成降低了系统复杂性。为了验证电力系统能量控制策略的工作效率，NEDC2000循环用于车辆驾驶测试，使用Matlab / Simulink建立了模糊逻辑控制器，并进行了与电力系统性能相关的组件的速度和扭矩分析。通过动态仿真表明，该模糊逻辑控制器可以适当地调节两个动力源（电动机和内燃机）。可以以低，中和高的驱动速度将内燃机维持在最佳运行区域。
