Validating the Evaluation of Driver’s Lumbar Fatigue State using Posture Measurement and EMG Measurement

Abstract

The purpose of this study was to investigate the back posture change and lumbar support position that can reduce driver's seating fatigue by using a muscle potential measurement device and a posture measurement device. We evaluated the back muscle activity and posture measurement in the seated state, and combined them with the results obtained from the posture measurement and driving fatigue evaluations conducted separately for a long period of time. As a result, it was confirmed that the driver's driving fatigue can be reduced by supporting the back position where posture changes occur with a decrease in muscle activity and a large amount of lumbar displacement.
