检测线上汽车动力性测试系统研究

Research on Automotive Tractive Performance On-Line Testing System

由于目前国内汽车动力性检测方法、检测设备和试验标定的数据不完善，导致测试结果存在较大误差。本文深入分析了影响测功结果的主要因素，建立了反拖式测功理论，以此为基础研制出反拖测功系统，可使检测结果准确有效。

Because of the unperfect testing technique, equipment and the data, the result contains higher error. This paper deeply analyses the key factors affecting the result, and build up reverse-drive power measuring theory. On the basis of this theory, we developed a reverse-drive power measuring system, which makes the testing result accurate and effective.
