摘　　要：本次研究通过对ECU控制策略的开发和整车相关零部件的改进,实现起动机加强技术型的智能起停系统,并据此完成整车NEDC循环试验,对比整车状态智能起停功能对整车油耗和排放的影响。实车试验结果表明,配置智能起停功能的车型与不带智能起停系统车辆排放基本相当,而油耗水平有较大提升。This paper introduces an i-stop （intelligent start-stop） system which contains new technology- based starter, by means of developing ECU （Electronic Control Unit） control strategies and improving components related to on vehicle. According to the results of vehicle NEDC （New European Driving Cycle ） cycle test, it analyzes the effects of this i-stop system on fuel consumption and emission performance. As the test results indicate, the vehicles equipped with this kind of i-stop system get some large benefits from fuel consumption compared to ones without i-stop system, keeping the equal emission performance.
