Effects of vibration on occupant driving performance under simulated driving conditions

摘要: Abstract Although much research has been devoted to the characterization of effects whole-body vibration on seated occupants' comfort, drowsiness induced by received less attention date. There are also little validated measurement methods available quantify whole body vibration-induced drowsiness. Here, were investigated. Twenty male volunteers recruited for this experiment. Drowsiness was measured in a driving simulator, before and after 30-min exposure vibration. Gaussian random vibration, with 1–15 Hz frequency bandwidth used excitation. During session, required obey speed limit 100 kph maintain steady position left-hand lane. A deviation lane position, steering angle variability, recorded analysed. Alternatively, rated their subjective Karolinska Sleepiness Scale (KSS) scores every 5-min. Following significant increase deviation, KSS observed all suggesting adverse human alertness level.
