摘要
在GB17691-2005国Ⅲ标准中对ETC试验工况回归分析算法允差进行了定义,对各种可以影响因素进行了说明,但没有给出对评价结果的影响,通过一个实例从时间偏移和扭矩可删点两个方面试图说明其潜在影响的大小。
GB17691-2005, China standard on Stage Ⅲ emission regulation, defines deviation to regression analysis of ECT test and describes varied factors affecting regression analysis. But the standard does not show effects of factors on evaluation. Effects of time axis and torque deleting condition on evaluation are discussed through a practical example.
