Abstract
Methods and systems are provided for filtering an oil dilution amount based on a current value of the oil dilution amount. In one example, filtering the oil dilution amount may include decreasing a sensitivity of filtering at lower oil dilution below a threshold; otherwise, increasing the sensitivity of filtering. The sensitivity of the filtering may be decreased by implementing a larger time constant, while the sensitivity of the filtering may be increased by implementing a smaller time constant.
