    摘要: A method and system is described for removing contamination from a conductive particulate matter sensor. The sensor has a substrate with two electrodes on the substrate configured to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes. The method includes heating the sensor to a first temperature for a first duration of time, wherein the first temperature and first time are sufficient to remove collected particulate matter from the sensor. The method further includes heating the sensor to a second temperature for a second duration of time, wherein the second temperature is higher than the first temperature, to remove contaminants that cannot be removed by heating to the first temperature for the first duration of time.

    摘要: A method of detecting particulate matter on a particulate matter sensor includes the steps of measuring an electrical characteristic associated with the sensor, determining a value corresponding to the impedance across the sensor, and compensating the impedance for the temperature at which it was determined. The method further includes determining an estimate of the total amount of particulate matter accumulated while limiting the effects of large particles captured on the sensor or blown off the sensor. The information produced by the method may be used to provide diagnostic information regarding a particulate control system.

    摘要: An engine control system which may be used in automotive vehicles includes first correlation data representing correlations between performance parameters associated with different types of performances of a combustion engine and uncorrelated common factors existing among the performance parameters and second correlation data representing correlations between the common factors and combustion parameters associated with combustion states of fuel in the combustion engine. The engine control system determines target values of the common factors using the first correlation data and also determines target values of the combustion parameters using the second correlation data. The engine control system determines command values as a function of the target values of the combustion parameter and outputs them to actuators which control combustion states of fuel in the engine for achieving desired levels of the performances of the combustion engine. This enables the performance parameters to be controlled independently of each other without any interference.

    摘要: A diagnostic method and system is described for diagnosing an operating condition of a conductive particulate matter sensor. The sensor has a substrate with electrical resistance that varies with temperature and two electrodes on the substrate adapted to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes, Relect. The diagnosis is performed by heating the substrate in the area between the electrodes and detecting whether resistance varies with temperature as expected, and then cooling the substrate back down and detecting whether resistance varies with temperature as expected. If resistance varies as expected during both heating and cooling, then a validation is diagnosed that the sensor is in proper operating condition if resistance increases in a manner consistent with evaporation of condensate. If resistance does not vary as expected, then a failure condition is diagnosed.

    摘要: A detection apparatus includes a detection unit, a control unit, a first setting unit, and a second setting unit. The detection unit is disposed in an exhaust path through which an exhaust gas flows, and detects a correlation value correlated with an amount of particulate matter (PM) attaching to an attachment element. The control unit controls a temperature of the attachment element to follow a target temperature while a regeneration process is performed to heat the attachment element so as to burn PM. The first setting unit sets the target temperature to be lower, as the amount of PM becomes larger. The second setting unit sets a completion timing of the regeneration process so that a period of the regeneration process becomes longer, as the amount of PM becomes larger or a temperature of the attachment element becomes lower while the regeneration process is performed.
