Effects of Different Car Pedal Systems and Driving Skills on Drivers’ Lower Extremity Postures during Fatigue
Abstract
The purpose of this study was to investigate drivers’ postures in different car pedal systems and skilledlevels under fatigue. Twenty four subjects participated in this experiment. For three-dimensional analyses, sixcameras (Proreflex MCU-240, Qualisys) were used to acquire raw data. The parameters were calculated andanalyzed with Visual-3D. In conclusion, ROAs of two leg-pedal system were less than one leg pedal systemby pattern analysis. Through statistical tests, skilled levels have effects on ROAs(X, Y, Z) of ankle joint atbreaking a pedal and ROAs(Y, Z) of ankle joint at accelerating a pedal. Also, car pedal systems have effectson ROAs(Y, Z) of ankle joint, and ROA(Z) of knee joint at accelerating a pedal. In addition, skilled levels andcar pedal systems (cross effects) have an effect on ROA(Z) of ankle joint. These findings suggested that weshould improve a present single pedal system.
