摘　　要：在介绍了发动机怠速停止起动系统工作原理的基础上,分析了发动机怠速和重新起动时的燃油消耗量,以及目前怠速停止起动系统的缺点。结果表明,短时间的怠速停止反而会因需要重新起动而增加发动机油耗。为此设计了一种汽车发动机智能怠速停止起动系统的控制策略,它能够根据交通信号灯确定的停车时间的长短来决定是否执行怠速停止。Based on the working principle of engine idling stop ＆ start system presented, the fuel consump- tions in engine idling and re-starting conditions as well as the deficiency of the existing idling stop ＆ start system are analyzed. The results show that the short time idling stop will contrarily increase fuel consumption due to the need of restart. To this end, a control strategy of the intelligent idling stop ＆ start system for vehicle engine is designed, with which a decision can be made on whether the idling should be depended on traffic light information. stopped based on the stop duration of the vehicle
