Abstract:
In a sensor control device which controls a sensor, a first filter unit extracts a first filtered signal obtained by attenuating a frequency component higher than a first cutoff frequency from a digital signal indicating a current-application control value for a pump current, and a second filter unit extracts a second filtered signal obtained by attenuating a frequency component higher than a second cutoff frequency from the first filtered signal. A cutoff frequency setting unit sets at least one of the first cutoff frequency and the second cutoff frequency such that the sensor control device can control at least two types of sensors.

Claim (Index 1):
A sensor control device configured to control a sensor including at least an oxygen pump cell which has a solid electrolyte and a pair of electrodes disposed on the solid electrolyte and which pumps oxygen into or out of a measurement chamber of the sensor in accordance with a pump current, the sensor being configured to detect a specific component contained in a gas to be measured, the sensor control device comprising:\n an analog-digital conversion unit configured to convert an inter-electrode voltage, which is an analog signal, generated between the pair of electrodes of the oxygen pump cell into a digital value; a current-application control value calculation unit configured to perform digital control to calculate a current-application control value for the pump current to be applied to the oxygen pump cell, based on the digital value of the inter-electrode voltage; a digital-analog conversion unit configured to generate the pump current to be applied to the oxygen pump cell, based on a digital signal indicating the current-application control value for the pump current; a first filter unit configured to perform digital calculation to extract a first filtered signal obtained by attenuating a frequency component higher than a predetermined first cutoff frequency from the digital signal indicating the current-application control value for the pump current; a second filter unit configured to perform digital calculation to extract a second filtered signal obtained by attenuating a frequency component higher than a predetermined second cutoff frequency from the first filtered signal extracted by the first filter unit; and a cutoff frequency setting unit configured to set at least one of the first cutoff frequency and the second cutoff frequencies, wherein the digital-analog conversion unit generates the pump current based on the first filtered signal, and the second filter unit outputs the second filtered signal as a pump current signal for detecting the specific component contained in the gas to be measured.
