摘要

This study compared the performance and energy management between a novel full hybrid electric powertrain and a traditional power-split hybrid system. The developed planetary gearset and dual clutch configuration provides five operation modes. Equations for the torque and speed of power sources for the planetary gearset and dual clutch system and the Toyota Hybrid System are firstly derived. By giving vehicle performance of gradability, maximal speeds in hybrid and pure electric modes, the power sources of the 210 kg target vehicle are: a 125 cc engine and two 1.8 kW motor and generator. The optimal tank-to-wheel efficiencies, ratios of circulating power, and operation points at specific vehicle speeds and out loads are calculated. Simulation results show that the dual-motor electric vehicle mode offers superior performance regarding electric drive; the low capacity of the battery is conducive to reducing manufacturing and maintenance costs; the tank-to-wheel efficiency is mainly operated above 20% while the power split electronic-continuously-variable-transmission mode is the major operation mode, and a maximum of 17% fuel economy improvement is achieved compared with the Toyota Hybrid System in most of the vehicle speed ranges. The outstanding performance warrants further real-system development, especially regarding the implementation in plug-in and sport hybrid powertrain designs.
