Influencing Factor Analysis of Cushion Comfort Based on Static Body Pressure Distribution

Abstract:

Cushion comfort had a significant impact on driving comfort and preventing driving fatigue in driving process. When suffered factors from vehicle, road and environmental, characteristic of driver’s body pressure distribution was different from single seats. According to cab space constraint, driver's field of vision and size of seat, a driver static body pressure distribution experiment was designed and a logistic regression model was established. Finally, the relationship between cushion subjective comfort level and ankle angle, sitting height and cushion average load was investigated. This theory will provide a new basis for research about cushion pressure distribution and driver subjective comfort evaluation psychology.
