摘　　要：所研究的发动机智能起停系统具有以下特点:自动熄火与自动起动的过程由系统自动控制,不需要驾驶员的干预;自动熄火与自动起动的控制以驾驶员意图识别与车辆状态判断为基础,确保停机与起动满足驾驶员与车辆的需要.此外,该系统采用起动机-发电机分离式布置,最大程度地沿用了原车的电器架构,减少了开发成本.样车测试结果为百公里油耗与二氧化碳排放均下降了约3.9%,HC等污染物排放没有发生明显变化,表明该发动机智能起停系统可有效地根据驾驶员的需求与车辆状态进行发动机的停机与起动控制.The intelligent engine stop/start control system automatically shuts off or restarts the engine without any additional operation of the driver.The auto-stop and auto-start are released according to the driver intention identification and vehicle state judgment.The system guarantees that every auto-stop and auto-start meets driver＇s requirement and vehicle permission.The system reserves the traditional separate starter and generator for least change to the vehicle electrical architecture.Test results show that the system could turn off the engine and restart it intelligently while according to the driver intention and vehicle state.The fuel consumption in NEDC was reduced about 3.9%.
