C omparative pictures between traditional method and multivariable parameter method 传统经验标定法和多变量标定效果对比? Technical term : multivariable parameter calibration technology ?技术名称: 多变量参数标定技术? P recision of the total factor calibration is the highest, but the number of experiments would increase geometrical times according to the number of the variable; the traditional calibration based on the experience of the engineers lacks precision and is hard to exploit the whole potentiality of the engine. ?全因子标定方法标定精度最高, 但是标定次数随着标定变量的增加呈几何倍的增长; 传统的工程师经验标定方法,标定精度差,难以挖掘发动机的潜力。? The number of experiments that the multi-variable calibration method takes is about 1/20 th of which the total factor method would take, and 1/5 th of what engineers would take based on their experience. T he result is close to the total factor calibration, which is much better than calibration based on experience of the engineers. Multivariable calibration is quite helpful in the ESC emission calibrations , as well as the optimization of the fuel consumption . ?多变量标定方法的试验次数大约为全因子的 1/20 ,为工程师经验标定的 1/5 。多变量标定技术的标定效果接近全因子方法,远远好于工程师经验标定方法。多变量标定技术使得 ESC 排放标定变得轻松,并能标定出最优的加权油耗率。?
