摘要： [Objective] An object is to provide a sensor control apparatus and a sensor-control-apparatus control method which can reduce variation in startup time among a plurality of times of execution of detection processing, in consideration of variation in output characteristic among a plurality of gas sensors.[Means for Solution] In a sensor control apparatus, before drive control (S55 to S80) is started, preliminary control is executed so as to supply a constant current to a second oxygen pump cell over a constant time, to thereby control to a constant level the amount of oxygen pumped from a second measurement chamber to the outside of the second measurement chamber (S40 to 50). The preliminary control is executed under control conditions of the sensor control apparatus which are determined for each gas sensor and are associated with the amount of oxygen pumped from the second measurement chamber to the outside thereof. The control conditions bring into a target range the concentration correspondence value calculated after start of the drive control which is started after the preliminary control is executed in a state in which a reference gas having a known concentration is introduced into the gas sensor.

摘要： A gas sensor including coating layers (64) and (69) of fluorine or a fluorine compound formed on the surface of a separator (60), including a front separator (61) and a rear separator (66), disposed inside a sheath (30). The coating layers (64) and (69) have water impermeability and water repellency. Even in the case where moisture contained in the atmosphere within a sheath (30) forms dew on the surface of the separator (60), the coating layers (64) and (69) prevent soaking of moisture into the separator (60), to thereby secure the insulation property of the separator (60). Also, the coating layers (64) and (69) having water repellency prevent a water droplet from spreading on the surface of the separator (60) with resultant formation of a film of water, to thereby prevent flow of leakage current via a film of water.

摘要： A gas sensor diagnostic method includes the steps of counting the reversal number of times that a target air-fuel ratio for an air-fuel mixture to be supplied to an internal combustion engine reverses from a rich side to a lean side or from the lean side to the rich side through a specific air-fuel ratio defined as a boundary of the rich and lean sides; obtaining a detection signal of gas sensor at constant time intervals during a diagnosis period between a timing when the count for the reversal number is started and a timing when the reversal number reaches a predetermined number; calculating a first moderated signal by applying a first moderation calculation to the detection signal, and a second moderated signal by applying a second moderation calculation to the detection signal; calculating a deviation between the first and second moderated signals; and determining whether the gas sensor is in the abnormal state on the basis of the deviation obtained during the diagnosis period.
