摘　　要：发动机怠速自动起停是混合动力汽车的重要工作模式,它能避免发动机在怠速下运行,有效减少燃油消耗、尾气排放和发动机磨损.对混合动力汽车起步时发动机起动动力学进行了系统研究,基于发动机起动过程的阻力特性的建模与仿真,提出了ISG电机驱动控制策略,建立了ISG电机-发动机的综合控制模型,进行了发动机起动过程中的动力学仿真.仿真结果表明,所采用的ISG电机满足快速起动发动机的时间要求.The behavior of engine automatic starting and stop under idle speed is an important working model for HEV(hybrid electric vehicle), which can avoid engine running under idle speed. So it can reduce engine fuel consumption, exhaust gas emission and wear efficiently. The ISG(integral starter/generator) motor control strategy is given by dynamic research of the HEV engine starting, based on the model and simulation of resistant characters during engine starting, then an ISG motor-engine integral control model is built up and simulated. The result shows that the ISG motor can drive engine quickly and the simulation meets well with the need of starting time.
