Verification of Reduction Effect of the Driver Fatigue Increase on Long Time Driving with an Air Cell Lumbar Support Device with a Hip Auxiliary Mechanism

Abstract

In this study, we propose the air cell lumber support device with a hip auxiliary mechanism for the reduction of the driver fatigue increase during long time driving. We measured the driving fatigue by using the driving simulator without support system or with lumber support system or the proposed system. From the experimental results, the reduction effect of the proposed system is more than that of the lumber support device and that of no support system. But there is a subject that the reduction effect are similar between the lumber and the proposed system because he does not slide the hip position during driving. Therefore, the effectiveness of the proposed system could be verified for the hip sliding driver during driving.
