  • Publication number: 20130283887
    Abstract: A method for operating a soot sensor in the exhaust gas tract of an internal combustion engine. The soot sensor includes an inter-digital electrode structure to which a measurement voltage is applied. Soot particles from the exhaust gas flow deposit themselves on the inter-digital electrode structure and an measuring current is evaluated as a measurement for the soot concentration of the soot sensor. A heating element for burning clean the inter-digital electrode structure is provided. The method for operating the soot sensor has good measurement results and the shortest possible idle time. To this end, a point in time for burning clean the soot sensor is determined in accordance with the operational state of the internal combustion engine and then, the burning clean of the inter-digital electrode structure starts by heating the soot sensor by the heating element.

  • Publication number: 20130090866
    Abstract: A diagnostic method for a soot sensor that lies in an exhaust gas system of an internal combustion engine. First, a first temperature in the exhaust gas system is detected, and it is determined whether the detected first temperature is below a 100° C. If this is the case, a first measured value is then detected with the soot sensor and compared with a specifiable threshold value. If the first measured value exceeds the specifiable threshold value, the soot sensor is determined to be operating properly.

  • Publication number: 20120255340
    Abstract: A particle sensor arranged in an exhaust duct such that particles from the exhaust-gas flow accumulate on and/or between at least two sensor electrodes when a voltage greater than a limit voltage is applied between the two sensor electrodes and substantially no particles accumulate if the voltage is lower than the limit voltage. During a first time period, a first voltage greater than the limit voltage is applied between the sensor electrodes. During a second time period, a second voltage, lower than the limit voltage, is applied between the sensor electrodes, and/or the particle sensor is heated to a predefined temperature, such that substantially no particles accumulate on and/or between the at least two sensor electrodes. Following the second time period, a third voltage greater than the limit voltage is applied between the sensor electrodes.

  • Publication number: 20110156727
    Abstract: A soot sensor for the detection of soot particles in an exhaust gas flow, having interdigitally engaged measurement electrodes applied on a substrate. An electrical resistance between the measurement electrodes is a measure of soot load of the exhaust gas flow. The measurement electrodes are divided into two regions, a first region in which no soot particles can be deposited and a second region where soot particles are deposited from the exhaust gas flow. The first region and the second region are exposed simultaneously to the other conditions prevailing in the exhaust gas flow.

  • Publication number: 20110005198
    Abstract: A diagnostic method is provided for a particle filter arranged in exhaust-gas flow of an internal combustion engine. A particle concentration is detected by a particle sensor positioned downstream of the particle filter. The combustion-relevant engine parameters are briefly changed by an engine controller in such a way that an untreated emissions concentration from the engine is significantly increased. A filter fault message is output if the detected associated measurement values of the particle concentration exceed a detection threshold value of the particle sensor, which is in particular considerably greater than a predefined, preferably volume-related particle limit value.

    Abstract: A method and a device for measuring a normal force affecting a disk brake that is used particularly in motor vehicles. In order to further develop a device for measuring an effective normal force so as to significantly decrease the additional mounting space required in the area of a disk brake and reduce sensitivity to thermal influences, a shearing movement of a part of the disk brake relative to a reference is detected by a sensor such that a test signal-processing logic circuit can draw conclusions about an actually effective normal force based on a sensor test signal.
