Apparatus and method for controlling a gas sensor










Image Number 3 for United States Patent #8404101.

A gas sensor control apparatus including internal resistance detection means for detecting an internal resistance value of one of cells of a gas sensor, concentration detection means for detecting a concentration value of a specific gas component in a gas to be measured and outputting the detected concentration value, heater current supply control means for controlling a current to be supplied to a heater of the gas sensor such that the detected internal resistance value becomes a target value, determination means for determining whether or not the detected internal resistance value is within a permissible range including the target value, and nullification setting means for setting the detected concentration value to a predetermined nullification concentration value to nullify the detected concentration value, when it is determined that the target value is out of the permissible range.
