The invention relates to a method for determining an effective prevailing uncertainty value () for an emission value () for a given time point when operating a drivetrain () of a motor vehicle with an internal-combustion engine (), wherein, at different times (n), one prevailing emission value () and one prevailing uncertainty value () are determined for the emission value, wherein the effective prevailing uncertainty value () for the given time point is determined from prevailing uncertainty values () and prevailing emission values () prior to the given time point.

Method for determining an effective prevailing uncertainty value for an emission value for a given time point when operating a drivetrain of a motor vehicle

The invention concerns a method () for operating a motor vehicle () with a combustion engine (), including the determination () of a current operating state of the vehicle (), the determination () of an emission state of the vehicle () during the determined operating state, carrying out () at least one measure to reduce emissions depending on the emission state and evaluating () the at least one measure in connection with the operating state with regard to its success in reducing emissions. Furthermore, a computing unit () and a computer program product for carrying out such a method () are proposed.

Method for operating a motor vehicle with a combustion engine

A method for monitoring emissions in the exhaust gas of an internal combustion engine in a vehicle, comprising carrying out () multiple successive emission measurements for at least one component in the exhaust gas, wherein each of the emission measurements is respectively performed after a driving distance of predefined length is covered by the vehicle; storing () a distance-related emission value (E), which was obtained () on the basis of the measurement, in a memory element () for each of the emission measurements; and forming () a smoothed emission level for a current point in time on the basis of multiple of the previously stored distance-related emission values, wherein more recent emission values are taken into consideration more strongly than emission values lying farther back in time in the formation of the smoothed emission level.
