摘要： A device for diagnosing an exhaust gas sensor, in particular a linear oxygen probe, for an internal combustion engine. A diagnostic unit is configured to control a first and a second current source in a coordinated manner in order to generate a first and a second current. Each of the currents has a predefined polarity sign, and is designed to determine the first and/or second and/or third voltages applied at a first and/or second and/or third terminal when first and second currents flow and put the amounts of the voltages in relation to the coordinated currents such that line interruptions and/or short circuits can be detected at the first and/or second and/or third terminal.

摘要： A device for controlling an exhaust gas sensor that is alternatively configured as a limiting-current probe or as a two-cell probe. In each case, the probe has a reference cavity made of a ceramic material and a cell made of a material conducting oxygen ions. A controller has one input variable that is a measured sensor voltage dependent on an oxygen concentration in the sealed cell. The other input variable is a reference voltage. The output variable of the controller is a current which is to be applied to the cell and which allows the sensor voltage to be regulated to a predefined value. The device for controlling the limiting-current probe is designed to process the applied current in one of the input variables of the controller.

摘要： Depending on a trim controller diagnosis, a suspicion marker for an asymmetric ageing of the exhaust gas probe is allocated either a “true” value or a “false” value and, if the value of the suspicion marker is “true”, a dynamic diagnosis will be performed based on the exhaust gas probe's measuring signal, on the basis of the results of which diagnosis either an asymmetrically aged or a non-asymmetrically aged exhaust gas probe will be detected.

摘要： In relation to a jump (SP_J_LR) from a lean air-to-fuel ratio to a richer air-to-fuel ratio, a measurement signal of the exhaust gas probe is detected after a predetermined lean-to-rich delay (t_R) as a lean-to-rich signal value (SV_LR) and is placed in relation to a lean-to-reference signal value (L_REF). In relation to a jump (SP_J_RL) from a richer air-to-fuel ratio to a leaner air-to-fuel ratio, the procedure is performed equivalently. Depending on the lean-to-rich and lean-to-rich signal value put in relation, either an asymmetrically aged or non-asymmetrically aged exhaust gas probe is detected.
