    • The invention relates to a method for diagnosing a particle filter used for filtering particles out of the exhaust gas of an internal combustion engine, wherein a collecting particle sensor is disposed downstream of the particle filter in the direction of flow of the exhaust gas and wherein a measurement for the loading of the particle sensor is determined from an output signal of the particle sensor. Provision is thereby made for the temporal integral of a parameter correlating to the particle emissions of the internal combustion engine to be formed during a measurement cycle, for the measurement for the loading of the particle sensor to be associated with the integral at least one measurement point in time during the measurement cycle and for a defective particle filter to be suggested if the measurement for the loading of the particle sensor is higher than a loading threshold value associated with the integral or if the integral is lower than an integral threshold value associated with the measurement for the loading of the particle sensor. The invention further relates to a device for carrying out the method. The method and the device allow for the diagnosis of the functionality of a particle filter in the exhaust gas of an internal combustion engine during any operating conditions passed through by the internal combustion engine.

    • The invention concerns a procedure to determine a mass of particles or a particle mass flow in an exhaust gas system of an internal combustion engine, whereby at least one resistive particle sensor is disposed in the exhaust gas system of the internal combustion engine. The measured signal change of the particle sensor is compared with a predicted signal change of the particle sensor ascertained from an engine model.If the measured signal change of the particle sensor and/or the predicted signal change of the particle sensor are corrected while taking into account the influencing variables on the transverse sensitivities of the particle sensor, it is possible when ascertaining the predicted signal change of the particle sensor that a compensation for the transverse sensibilities can result even during dynamic operating point changes of the internal combustion engine, which occur faster than the actuation of the particle sensor. This is the case because the correction can even be implemented for small predicted signal changes, such as those occurring during a currently transpiring operating point of the internal combustion engine. Because the predicted signal changes are ascertained from a set of characteristic curves of the engine model, these measurement intervals capable of being assigned to very short times and for that reason to individual operating points of the internal combustion engine can be determined with the very small predicted signal changes, which are required for this purpose.
