Abstract

A state determination apparatus (100) is a state determination apparatus (100) adapted to determine a state of at least one of an air control valve (24, 28) or a flow path (20) used in a vehicle brake, wherein the air control valve (24, 28) discharges air with an output pressure corresponding to an input pressure, which is a pressure of air introduced, to a supply flow path leading to a brake cylinder (16t), the state determination apparatus (100) including: an acquisition unit (110) that acquires a first measurement value of the input pressure and of the output pressure at one or more points of time in a pressure intensification period in which the input pressure increases and acquires a second measurement value of the input pressure and of the output pressure at one or more points of time in a pressure reduction period in which the input pressure decreases; a calculation unit (120) that calculates a difference in at least one of the input pressure or the output pressure between the pressure intensification period and the pressure reduction period, based on the first measurement value and the second measurement value; and a determination unit (130) that determines a state of at least one of the air control valve (24, 28) or the flow path (20) according to the difference.
