沈阳市乘用车城市道路工况试验研究

基于实验室台架测量的汽车工况研究方法由于受到场地、车型及台架测量范围等因素的影响,已不能很好地反映车辆实际应用时的行驶工况。车载测试方法是在实际行驶条件下采集车辆数据,并进一步进行处理分析,以获得更符合实际状况的车辆行驶工况的方法,该方法既不影响车辆的正常使用,又可避免在实验室测量时产生的一些问题。最后通过对最终构建的行驶工况的验证,证明了车载测试试验方法的合理性。

Experimental study on urban road condition of passenger vehicles in Shenyang

The research method of the vehicle condition based on the bench test can not reflect the vehicle driving cycle when it is applied in the practical application. The vehicle test is in the actual driving conditions of vehicle data acquisition, and further analysis, in order to get a more practical vehicle driving conditions, this method does not affect the normal use of the vehicle, but also can avoid some of the problems generated in the laboratory measurement. Finally, the rationality of the vehicle test method is proved by the verification of the final driving condition.
