Filed: 2003-04-30
Abstract: <P>PROBLEM TO BE SOLVED: To restrain reduction of detection accuracy of an ion current upon detection of the ion current using a glow plug.  <P>SOLUTION: In this ion current detection device 1, a processing start timing of S140 (namely, a starting timing of an ion current detection period) is set to a point in which a detection delay time passed from a starting timing of a voltage application period for detection. The detection delay time used for a processing at S130 of a drive signal control processing is set so as to be longer than a spike current generation period. Consequently , the spike current generation period is not included in the ion current detection period, and upon detection of the ion current, affection due to the spike current is prevented. Accordingly, since the affection due to the spike current can be restrained, erroneous detection of the spike current as the ion current can be prevented, thereby preventing the reduction of the detection accuracy of the ion current.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
