摘要： There are provided a combustion start determination unit that determines whether or not the inner-cylinder state of an internal combustion engine has changed from a non-combustion state to a combustion state; and a filter coefficient changing demand unit that outputs a filter coefficient changing demand until a predetermined filter coefficient changing period elapses from the time instant when the combustion start determination unit determines that the inner-cylinder state of the internal combustion engine has changed from the non-combustion state to the combustion state to the time instant. Based on the filter coefficient changing demand, at least one of a background level calculation unit and a standard deviation calculation unit changes the value of a filter coefficient utilized in a filtering operation to the one with which a filtering effect is weakened.
