Abstract
A monitoring unit that serves as a tire pressure monitoring device includes an acquisition section, a calculation section and a determination section. The acquisition section acquires air pressure data of plural tires mounted at a vehicle. On the basis of the air pressure data, for each tire, the calculation section calculates a first representative value relating to air pressures of the tire in a first period, calculates a second representative value relating to air pressures of the tire in a second period that is longer than the first period, and calculates a decrease level of the first representative value relative to the second representative value. The determination section determines that air pressure is decreasing when the decrease level of one tire is equal to or more than a first threshold value and the decrease level of another tire, which is different from the one tire, is less than the first threshold value.
