    • The invention relates to a method for operating an exhaust gas system of a vehicle in which an amount of a reducing agent to be supplied to the exhaust gas of an engine is determined. Measurements are evaluated which indicate a content of nitrogen oxides in the exhaust gas downstream of a catalytic device (12) adapted to diminish the content of nitrogen oxides in the exhaust gas. A magnitude and a frequency of the measurements are taken into account in determining the amount of the reducing agent to be supplied to the exhaust gas. Herein a plurality of measurements is captured during a predetermined period of time. A magnitude of a measurement captured within this period of time is related to a quantity which is derived from the respective magnitudes of the plurality of measurements captured during the predetermined period of time. The related measurement is then utilized to determine the amount of the reducing agent to be supplied to the exhaust gas. The invention further relates to a control assembly (10) for operating an exhaust gas system.
    • 本发明涉及一种操作车辆排气系统的方法,其中确定了向发动机排气供给的还原剂的量。 评估测量值,其表示在适于减少废气中的氮氧化物含量的催化装置(12)下游的废气中的氮氧化物的含量。 在确定供给废气的还原剂的量时,考虑测量的大小和频率。 这里,在预定时间段内捕获多个测量。 在该时间段内捕获的测量值的大小与从预定时间段内捕获的多个测量值的相应大小导出的量有关。 然后使用相关的测量来确定要供应到废气的还原剂的量。 本发明还涉及一种用于操作废气系统的控制组件(10)。
