A monitoring unit, which is a tire pressure monitoring device, is provided with: an acquisition unit that acquires pressure data of a plurality of tires mounted on a vehicle; a calculation unit that, on the basis of the air pressure data, calculates a first representative value relating to the air pressure for each tire in a first period and a second representative value relating to the air pressure for each tire in a second period that is longer than the first period, and calculates the degree of reduction of the first representative value with respect to the second representative value for each tire; and a determination unit that determines that there is a drop in air pressure when the degree of decrease in one tire is equal to or greater than a first threshold value and the degree of decrease in another tire different from the one tire is less than the first threshold value.
作为轮胎气压监视装置的监视单元具备:获取部,其获取安装于车辆的多个轮胎的气压数据;计算部,其基于所述气压数据,计算第一期间内的各轮胎的与气压有关的第一代表值且计算比所述第一期间长的第二期间内的各轮胎的与气压有关的第二代表值,并且针对每个轮胎计算所述第一代表值相对于所述第二代表值的减少度;以及判定部,其在一个轮胎的所述减少度为第一阈值以上且与一个轮胎不同的其它轮胎的所述减少度小于所述第一阈值的情况下,判定为存在气压的下降。
