Verification of Reducing Effect of Driver Fatigue Increase by Using the Driver's Seat with Two Support Mechanisms

In this study, to reduce the driver fatigue increasing for a long time driving, we examined the reduction effect of driver fatigue by the two back support part that were the pelvis support and the lumber support. From the results of the long time driving experiment by using the driving simulator, we evaluated the driver fatigue and clarified the difference of the reducing effect between two support mechanisms based on the biological information and the subjective evaluation.
