In this paper we present the evaluation of ride comfort by using brain waves. A questionnaire is used most frequently in the evaluation of ride comfort. However, there are some problems in evaluation only by the questionnaire, that an evaluation criterion is different depending on a person and it lacks objectivity. So we paid attentions to electroencephalography as objective and physical quantity. The electroencephalography is suitable for a experiment because it is non-invasive and a device is very handy. The measured electroencephalography is digitalized into four numbers by emotion spectrum analysis method, as four emotional levels such as anger, pleasure, sadness and relax, and the points of ride comfort are calculated. There are four patterns of graph how people feel the vibration, such as upper right type, parabola type, lower right type and constant type. We confirmed that there are some differences between the subjects how to feel the vibration.
