激烈驾驶行为导致的排放在机动车排放中占有较高的比重.本研究尝试开发并检验一款生态驾驶智能手机应用,以实时提醒驾驶员减少激烈驾驶行为,从而减少机动车排放.为此,本研究基于Android手机平台,通过实时监测机动车比功率(Vehicle Specific Power , VSP)的方法,开发出可给予驾驶员实时提醒的手机应用.然后,利用车载尾气监测系统(Portable Emission Measurement System, PEMS)和全球定位系统(Global Positioning System, GPS),收集测试车辆在使用生态驾驶智能手机应用前、后的逐秒排放和速度数据.实测数据显示,在使用该生态驾驶手机应用的情况下,测试车辆的VSP分布形态发生了改变,导致其排放状况也随之发生变化.测试车辆排放物中的CO,CO2和NOx排放量降低,而HC排放则有所升高.%Aggressive driving is responsible for a significant share of vehicle emissions. This paper attempts to develop and tests an eco-driving smartphone APP, which provides warnings to drivers to mitigate aggressive driving behaviors, thus reducing vehicle emissions. To this end, the eco-driving APP is developed in a smartphone with the Android platform, which provides real time warnings to drivers on their driving behaviors that are out of the threshold range, which is defined based on the concept of Vehicle Specific Power (VSP) distributions. It is then evaluated by collecting the instantaneous driving activity and the associated emissions data of a test vehicle equipped with a portable emission measurement system (PEMS) embeds with an on-board Global Positioning System (GPS) logging device, which records the vehicle's instantaneous position and speed, and the associate emissions. It is shown from the study that with the warnings provided by the eco-driving APP, the driving behaviors shifts to the driving patterns, which leads to reductions in vehicle emissions. The CO,CO2 and NOx emissions are reduced substantially, whereas the HC emissions is increased.
