Publication number: 20230221234Abstract: A soot sensing system includes a soot sensor having a first element, and circuitry to an amount of soot accumulated on the element and to control heating of the element in response to the soot accumulation. An electrostatic repelling voltage (ERV) may be applied to a sensor/heater element(s) during a contamination prevention mode (CPM) to repel ash and reduce contamination of the sensor. A pulsed heating voltage (PHV) may be applied to the elements during the CPM and a pulsed ERV may be applied to the elements during the “off” period of the PHV. All voltage to the elements may be turned off during the CPM and the elements may be floating/ground. A PHV may be applied to the elements during the CPM and no voltage may be applied to the elements during the “off” period of the PHV. A heating voltage may be applied to the elements during a CPM corresponding to a cold start.Type: ApplicationFiled: September 22, 2022Publication date: July 13, 2023Inventors: Kayvan Hedayat, John Hart, Eric Matson, Mark Wilson, Norman Poirier

Patent number: 11137333Abstract: A soot sensor system and a method of sensing soot in a vehicle soot sensor system. The soot sensor system and method includes providing a soot sensor having at least one trace of conductive material in a continuous loop on a surface of a substrate, applying an alternating current (AC) input voltage to the at least one trace of conductive material to establish an AC sense current through the at least one trace of conductive material, and generating, using a peak detector, a peak detector output voltage representative of a peak value of the AC sense current and of an amount of soot accumulated on the soot sensor.Type: GrantFiled: August 6, 2019Date of Patent: October 5, 2021Assignee: STANDARD MOTOR PRODUCTS, INC.Inventors: Kayvan Hedayat, John Hart, Eric Matson, Mark Wilson, Norman Poirier
