摘要： A water level measuring apparatus and a water level measuring method, in which a water level L0 of a liquid is read from a water level indicator secured to a liquid tank, and a filter value FLT is calculated by applying a filter with a time constant greater than one second to the water level L0, and the filter value FLT is output as a final water level L. Accordingly, even if the surface sloshes and the water level L0 fluctuates up and down, the water level L0 is smoothed by the filter. Hence there is little influence of the liquid sloshing, and the water level measurement accuracy can be improved.

摘要： A sensor control device including an anomaly diagnosis section. When at least one of a first NOX concentration Ip2W based on the output OP1 of a first differential amplification circuit (210) and a second NOX concentration Ip2N based on the output OP2 of a second differential amplification circuit (220) falls within an anomaly diagnosis range ZN, the difference D between Ip2W and Ip2N is obtained, and the difference D is stored in a difference accumulation buffer BF such that 16 values of the difference D continuously sampled up to the present are stored. The integrated value (difference integral value) Dint of the difference D is obtained. When the difference integrated value Dint becomes equal to or greater than a predetermined value Di0, the sensor control device indicates a diagnosis result of “anomalous.”

摘要： A sensor control apparatus connected to a gas sensor includes a microcomputer containing a ROM (first storage section), and an EEPROM (second storage section) independently of the ROM. The ROM stores an anomaly diagnosis program containing at least one type of anomaly determination process. The EEPROM stores one or more flags set so as to represent whether the corresponding anomaly determination process is valid or invalid. The states of the one or more flags can be readily changed from an externally connected PC. A CPU executes a series of processing steps of the anomaly determination processes, and then obtains a determination result thereof when the CPU determines that the anomaly determination process is valid, with reference to the one or more flags.

摘要： In an oxygen sensor control apparatus, after start of fuel cut, the weighted average Ipd of corrected values obtained by multiplying the output value of a mounted oxygen sensor by a correction coefficient Kp is obtained as a representative value Ipe, representing the corrected values in the fuel cut period (S19). In the case where the number of times the representative value Ipe is continuously judged not to fall outside a second range (S21: NO) and to fall outside a first range (S23: YES) reaches 10 (a first number of times) (S26: YES), a new correction coefficient Kp is computed (S27). In the case where the number of times the representative value Ipe is continuously judged to fall outside the second range (S21: YES) reaches 4 (a second number of times smaller than the first number of times) (S29: YES), a new correction coefficient Kp is computed (S30).
