Prediction of drivers comfort and discomfort from interface pressure distributions
The information of the pressure patterns at the driver-seat interface are very useful for the design of seats. However, a clear and consistent relationship between interface pressure and driving comfort and discomfort was not identified. This study examined associations between three subjective ratings (overall, comfort, and discomfort) and over 100 measures describing driver-seat interface contact pressure, force and area and ratios of local to whole body. This requires quantitative and dynamic analyses of body pressure distribution. Each of eight subjects performed a simulated driving task for 100 minutes in a driving simulator. The body-seat interface pressure were measured continuously, and the subjective ratings were surveyed at the prescribed interval. In this study, it was clarified that there was a possibility to predict comfort/discomfort from several body pressure variables. And some specific approaches were proposed for the intervention of the drivers physiological state, such as decreasing the force ratio, area ratio and pressure ratio levels in the left buttock and the left thigh, and balancing of the contact area ratio of buttocks and the force ratio of both thighs.
