Abstract
A deterioration determination apparatus includes an oil temperature detector, an oil temperature rate of increase calculator, a threshold calculator, and a deterioration determination device. The oil temperature detector is configured to detect an oil temperature of oil for lubrication of a transmission in a vehicle. The oil temperature rate of increase calculator is configured to calculate a rate of increase in the oil temperature. The threshold calculator is configured to calculate based on a travel condition of the vehicle a first threshold. The deterioration determination device is configured to compare the rate of increase in the oil temperature with the first threshold. The deterioration determination device is configured to determine that the oil is deteriorated when the rate of increase in the oil temperature is equal to or higher than the first threshold.
