【摘要】：首先对换挡提示功能的节油原理和控制策略进行研究,然后在试验车辆上实现换挡提示功能并进行节油效果测试。结果表明,在NEDC和FTP循环中采用换挡提示功能后分别节油4.8%和4.4%,相当于熟练驾驶员的水平,说明换挡提示功能匹配合理。为达到量产的要求,还进行换挡提示功能对排放和车载诊断影响的研究,结果表明换挡提示功能对整车排放几乎没有影响,重新标定车载诊断条件后各项诊断均符合法规要求。
[Abstract]:Firstly, the fuel saving principle and control strategy of shift warning function are studied, and then the shift prompt function is realized on the test vehicle and the fuel saving effect is tested.The results show that the fuel saving of 4.8% and 4.4% is equivalent to the level of the skilled driver in NEDC and FTP cycle, which shows that the matching of shift prompt function is reasonable.In order to meet the requirement of mass production, the effects of shift warning function on emissions and on-board diagnosis are also studied. The results show that the shift warning function has little effect on the emission of the whole vehicle, and all the diagnoses after re-calibrating the condition of on-board diagnosis are in accordance with the requirements of laws and regulations.
