Verification of the Driver's Fatigue Accumulation Reduction Effect at the Long-time Driving by Back Support Position Change

In this study, we investigated the driver's fatigue reduction effect at multiple support positions in order to reduce the driver's fatigue during long driving.We examined each posture change when supporting the lumbar at these multiple support positions.Then, the long time driving experiments using a driving simulator were conducted to evaluate the driving fatigue.Based on these results, we clarified the difference in fatigue reduction effect due to the difference in support position based on biological information and subjective evaluation.
