  • Method for assessing a condition of a particulate filter and exhaust system for a motor vehicle
    Patent number: 10933363
    Abstract: In a method for assessing a condition of a particulate filter for use in an internal combustion engine of a motor vehicle, a difference between a pressure exerted on the input side of the particulate filter and a pressure exerted on the output side of the particulate filter is recorded by a differential pressure sensor. The difference in pressure is taken into account when assessing the condition. Furthermore, the pressure exerted on the output side of the particulate filter in relation to the atmospheric pressure is recorded by a relative pressure sensor. When assessing the condition of the particulate filter, the pressure recorded by the relative pressure sensor is also taken into account. A frequency of changes in pressure and/or an amplitude load of the pressure is assessed. The invention also relates to an exhaust system for a motor vehicle.
