摘　　要：以某轻度混合动力电动汽车为对象研究整车功率分配策略,详细分析驾驶员功率需求确定、发动机工作区域优化和制动能量回收控制策略,并在此基础上开发了多能源动力总成控制器的硬软件系统。通过对多能源动力总成控制器的硬件在环仿真试验和实车匹配测试,不仅证明该控制器能高效、可靠地运行,而且取得了降低整车油耗16．9％,排放指标远低于欧III标准的控制效果。Based on the detailed analysis of power demand of driver, engine operating area optimization and brake energy recovery strategy, an energy management strategy of hybrid electric vehicle（HEV）, together with the hardware and software system of powertrain controller, is developed to analyze specific mild HEV. Through the hardware-in-the-loop test and real vehicle calibration test, the functions of powertrain controller are validated. The test results show that by using this powertrain controller, HEV can achieve better control performance, with not only 16.9% fuel consumption reduced but also lower emissions than Euro Ⅲ.
