摘要： In a method and a control device for operating a broadband lambda sensor in which the oxygen concentration of an exhaust gas is determined on the basis of a comparison of a Nernst voltage with a reference voltage having a nominal value, and a pump current is injected into a cavity of a pump cell if a deviation is present, an electric voltage present at the pump cell being regulated in such a manner that lambda=1 prevails in the cavity, the pump current being a measure for the value of lambda in the exhaust gas, in order to avoid control interference in the start phase of the engine or in the cold phase of the sensor, it is provided that the Nernst voltage is maintained close to the reference voltage, using a pilot control, until the Nernst voltage is an actual measure for the oxygen concentration in the cavity of the pump cell.
摘要翻译：在用于操作宽带λ传感器的方法和控制装置中，其中基于能斯特电压与具有标称值的参考电压的比较来确定排气的氧浓度，并且泵浦电流被注入泵单元的空腔如果存在偏差，那么存在于泵室的电压以这样的方式被调节，使得λ= 1在空腔中占优势，泵电流是排气中的λ值的量度为了避免在发动机起动阶段或传感器的冷相中的控制干扰，只要使用先导控制将能斯特电压保持接近参考电压，直到能斯特电压为实际值测量泵电池腔中的氧浓度。
