It is problem that sensory evaluation can't sufficiently express man's subjectivity. Then, measurement of the electroencephalogram is an effective method. The purpose of this study is to evaluate mental workload about increasing speed 60km/h to 120km/h and state of pseudodrinking with a driving simulator. Subjects entered the state of pseudodrinking putting on special glasses. The principal component analysis of the sinciput beta wave and the emotion spectra analysis were done by using the electroencephalogram. The result of the principal component analysis was assumed to be a level of concentration and the result of the emotion spectra analysis was assumed to be a level of relaxation. As subjects feel in a strong stress, a level of concentration is going up and a level of relaxation is falling. It is clear that these values are correlated with each other.
