An arousal level estimating apparatus of a vehicle for estimating an arousal level of a driver, comprises: an operation quantity detecting means for consecutively detecting an operation quantity of said vehicle; a power calculating means for calculating a frequency component power by applying a frequency conversion to said operation quantity; a low frequency domain establishing means for establishing a low frequency domain lower than a reference frequency; and a judging means for judging that an arousal level of said driver is declined when said frequency component power exceeds a first threshold value in said low frequency domain. <IMAGE> |
