Abstract
An oil condition estimation device includes a first acquisition unit that acquires a pressure of oil stored in an oil pan from a pressure sensor provided on a bottom surface of the oil pan of an internal combustion engine, a second acquisition unit that acquires a distance between the bottom surface and a liquid level of oil from a level sensor provided in the oil pan, and a calculation unit that calculates a density of oil on the basis of the pressure and the distance.
