用于检测柴油机颗粒过滤器破损的方法
相关申请的交叉引用
本申请要求2011年12月5日提交的韩国专利申请No.10-2011-0129254的优先权，该申请的全部内容结合于此，以用于通过该引用的所有目的。
技术领域
本发明涉及一种用于检测柴油机颗粒过滤器破损的方法。更具体地，本发明涉及一种利用监控来检测柴油机颗粒过滤器破损的方法。
背景技术
通常，柴油机颗粒过滤器（DPF）是用于去除柴油发动机的废气中的颗粒物（PM）的过滤器。近来，具有优异的输出和燃油消耗量的柴油发动机的使用量已经增加。但是，关于柴油发动机的废气的国际法规也更加严格。因此，各种后处理设备被安装在柴油发动机车辆中以应对国际法规。此外，作为安装在柴油发动机车辆中的后处理设备中的一种，DPF被广泛地使用。DPF收集并过滤从柴油发动机排出的PM。此外，当废气中的PM累积到预定量的时候，DPF反复地进行再生从而通过升高废气的温度来使得煤烟燃烧。在DPF的再生中，对过滤器中累积的煤烟量的精确预测是非常重要的。经常使用一种根据DPF的前端部分和后端部分之间的压力变化来预测煤烟量的方法。此外，当通过监控而确定了DPF的前端部分和后端部分之间的压力变化高于预定值时，则确定DPF发生了破损。但是，根据传统的检测DPF破损的方法只能是当DPF中的基体完全损坏时，才能检测到DPF的破损。因此，不能由DPF微小的破损来检测到收集PM的效率的降低。
公开于本发明背景部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。
发明内容
本发明的各个方面提供了一种用于检测柴油机颗粒过滤器（DPF）破损的方法，所述方法具有能够检测DPF微小破损的优点。
一种用于检测柴油机颗粒过滤器（DPF）破损的方法可以包括：当所述DPF的再生终止时获取所述DPF中的流阻的已知值；计算所述流阻的预测值；确定所述已知值是否在所述预测值的允许误差范围内；以及如果所述已知值不在所述允许误差范围内，则确定所述DPF已破损。
所述方法可以进一步包括：存储根据车辆的英里数的所述已知值的算术平均数；以及将所述英里数和所述已知值之间的关系转换成多项式。
所述预测值可以通过使用所述多项式来计算。
如果所述已知值在所述允许误差范围内则重复以上步骤。
本发明的方法和装置具有其他的特性和优点，这些特性和优点从并入本文中的附图和随后的具体实施方式中将是显而易见的，或者将在并入本文中的附图和随后的具体实施方式中进行详细陈述，这些附图和具体实施方式共同用于解释本发明的特定原理。
附图说明
图1是根据本发明的用于检测柴油机颗粒过滤器破损的示例性方法的流程图。
具体实施方式
现在将具体参考本发明的各个实施例，在附图中和以下的描述中示出了这些实施例的实例。虽然本发明与示例性实施例相结合进行描述，但是应当了解，本说明书并非旨在将本发明限制为那些示例性实施例。相反，本发明旨在不但覆盖这些示例性实施例，而且覆盖可以被包括在由所附权利要求所限定的本发明的精神和范围之内的各种替换、修改、等效形式以及其它实施例。
图1是根据本发明的各个实施方案的用于检测柴油机颗粒过滤器破损的方法的流程图。
如图1所示，根据本发明的各个实施方案的用于检测柴油机颗粒过滤器（DPF）破损的方法包括：在S100步骤中，当所述DPF的再生终止时，在S110步骤中获取所述DPF中的流阻的已知值；在S 120步骤中存储根据车辆的英里数的所述已知值的算术平均数；在S130步骤中将所述英里数和所述已经值之间的关系转换成多项式；在S140步骤中计算所述流阻的预测值；在S150步骤中确定所述已知值是否在所述预测值的允许误差范围内；以及在S160步骤中，如果所述已知值不在所述允许误差范围内，则确定所述DPF已破损。
电子控制单元（ECU）储存在S100步骤中当所述DPF的再生终止时，在S110步骤中获取的所述DPF中的流阻的值。这里，步骤S110可以包括ECU确定DPF的再生终止的步骤。此外，所存储的流阻的值成为DPF中流阻的已知值。同时，流阻是DPF的前端部分和后端部分之间的压力变化除以废气量得到的值。
如果获得了流阻的已知值，则ECU储存在S120步骤中根据车辆的英里数的所述已知值的算术平均数。此外，ECU在S130步骤中将所述英里数和所述已经值之间的关系转换成多项式。这里，多项式可以是二次多项式。
如果建立了所述二次多项式，ECU则在S140步骤中计算所述流阻的预测值。也就是说，该预测值通过二次多项式来计算。
如果计算了预测值，ECU则在S150步骤中确定所述已知值是否在所述预测值的允许误差范围内。这里，该允许误差可以由本领域普通技术人员来设定。
在S160步骤中，如果所述已知值不在所述允许误差范围内，则ECU确定所述DPF已破损。
同时，如果所述已知值在所述允许误差范围内，则所述方法回到步骤S110。
根据所述用于检测DPF的破损的方法，可以检测到DPF微小的破损。
为了方便解释和精确限定所附权利要求，术语前或后等是用于参考图中显示的这些特征的位置来描述示例性实施方式的特征。
前述对本发明的具体示例性实施方案的描述是为了说明和例证的目的。这些描述并非想穷尽本发明，或者将本发明限定为所公开的精确形式，并且很显然，根据上述教导，可以进行很多改变和变化。对示例性实施例进行选择和描述的目的在于解释本发明的特定原理及其实际应用，从而使得本领域的其它技术人员能够实现并利用本发明的各种不同的示例性实施方案以及各种不同的选择和改变。本发明的范围意在由所附的权利要求书及其等同形式所限定。
