In this study, the moods of drivers were estimated using physiological information; fluctuations in heart rate were measured by an electrocardiogram to measure autonomic nervous activity. We estimated the level of relaxation of drivers during driving by comparing the sympathetic nervous and parasympathetic nervous activities of drivers when they are driving cars with and without an active seat suspension. A frequency analysis of the nervous activities was carried out using a real-time system that analyzes the fluctuations of heart rate. The moods of the drivers were also examined using a questionnaire to evaluate the correlation between the moods of drivers during driving estimated on the basis of electrocardiographic measurements and those estimated on the basis of responses to the questionnaire. Furthermore, their correlation was also examined by conducting a questionnaire survey with a five-point scale with three as a reference value to examine the subjective ride comfort of drivers in cars with and without an active seat suspension.
