    摘要: Provided is a DPF failure detection device not only capable of a quick detection but also having less erroneous and a small power consumption. The DPF failure detection device, after starting applying a dust collecting voltage to a dust collecting electrode, applies a measuring voltage to a measuring electrode while the dust collection voltage is being applied, thereby measuring the capacitance of a sensor device. The DPF failure detection device also stops applying the dust collecting voltage to the dust collecting electrode in response to the fact that the measured value (CCOL) of this capacitance exceeds a completion criterion (CCOL—TH). Further, the DPF failure detection device applies the measuring voltage to the measuring electrode, thereby measuring the capacitance of the sensor device and obtaining a measured value (CPM), on the basis of which a DPF failure is determined.
