摘　　要：为有效辨识驾驶员的驾驶意图,提高混合动力汽车整车燃油经济性,提出了一种根据驾驶员实时需求功率及发动机万有特性来即时调整发动机、电机扭矩分配的方法。通过对整车燃油消耗量的分析,构建了整车实时瞬时燃油消耗率最小目标函数,从而实时计算并调整整车扭矩分配,使发动机、电机维持综合效率最高状态运行。试验结果表明,此方法可使百公里油耗降低5.01%。To effectively identify the driver's driving intention and improve the fuel economy of the hybrid vehicle,a method of adjusting the torque distribution of the engine and motor in real time according to the real-time demand power of the driver and the universal characteristics of the engine is proposed.Through the analysis of the fuel consumption of the whole vehicle,the minimum objective function of the real-time instantaneous fuel consumption rate of the whole vehicle is constructed,so as to calculate and adjust the torque distribution of the whole vehicle in real time,so that the engine and motor can maintain the highest comprehensive efficiency.The test results show that this method can reduce the fuel consumption by 5.01%per 100 kilometers.
