  • Method for evaluating the plausibility of a pressure difference value determined across a particle filter
    Patent number: 8069713
    Abstract: In a method for achieving plausibility of a pressure difference value by means of a particle filter, a pressure difference value is allocated to each charging pressure of the internal combustion engine. As a result, the identification of a faulty pressure difference value occurs when the detected pressure difference value is outside a limit range of the detected charging pressure value.
