20120025813 | DETECTING INDUCTIVE OBJECTS USING INPUTS OF INTEGRATED CIRCUIT DEVICE - An system for detecting inductive objects includes an inductive sensor circuit for detecting changes in an electromagnetic field (“EMF”) environment and an integrated circuit (“IC”) device. The inductive sensor circuit generates an oscillating analog waveform with an envelope that indicates changes in the EMF environment. The oscillating waveform is coupled to the digital input pin of the IC. A digital interface circuit in the IC is coupled to the digital input pin and is configured for detecting if the oscillating waveform exceeds high and low threshold voltage levels. The detecting results in a digital pulse which represents changes in the EMF environment. In another implementation, a timer input capture pin can be used to detect the waveform envelope decay by storing the time when the waveform crosses a threshold value during a time period.

The particulate load in the diesel particulate filter is determined to exceed a minimum predetermined threshold amount which is sufficiently high to warrant regeneration of the filter. Current vehicle conditions are determined to exist that permit the establishment of appropriate conditions in the exhaust system to affect regeneration of the particulate loaded filter by appropriately configuring the AMT. The immediate future driving conditions are analyzed to assure they permit operation of the combustion engine under sufficient load and at sufficiently low speeds to maintain a sufficiently high regeneration temperature and exhaust flow in the exhaust system under the control of the AMT to affect regeneration of the diesel particulate filter. Finally, successful regeneration of the filter is executed by appropriately configuring the AMT to cause the combustion engine to run in a manner that establishes a sufficiently high regeneration temperature and exhaust flow in the exhaust system and that is maintained for a prescribed period of time. | 12-10-2009 |
