摘要
针对汽车仿真软件ADVISOR2002中并联式混合动力汽车的默认电力辅助控制策略(EACS)未对发动机转矩进行良好的分配以及未限制电池运行状态,导致的发动机工作效率较低及电池可能出现过冲与过放现象等问题,通过基于发动机转矩分配的思想制定了一系列规则,提出一种新的基于转矩分配的改进控制策略(TDCS),将发动机的输出转矩限制在高效区域,并同时控制电池的开关状态.仿真结果表明,在特定工况下,改进的控制策略不仅能有效提高发动机工作效率,而且对蓄电池也有一定保护作用.
Since the default electric assisted control strategy(EACS) of parallel hybrid electric vehicle in the vehicle simulation software ADVISOR2002 can not distribute the engine torque for good and does not limit the battery working state, resulting in low engine efficiency and the battery overcharging or discharging and other issues, this paper proposed a new improved control strategy based on torque distribution(TDCS) through a series of rules based on the idea of engine torque distribution. It will limit the output torque of the engine in the high efficiency area, and control the battery switch state at the same time. The simulation results show that the improved control strategy can not only improve the efficiency of the engine, but also have a certain protective effect on the battery under certain conditions.
