ABSTRACT

Proper driving requires a proper posture to bring comfort to drivers.  A problem that commonly exists in driving is incorrect driving posture which can cause discomfort to the driver, especially when interacting with automotive pedals.  Research on contraction of tibialis anterior (TA) muscle on driver's posture based on the knee angle less than 101º in a position of pressing and releasing a pedal was conducted to investigate and overcome this problem.  This is a field experiment study and surface electromyography (sEMG) is used in collecting data on the TA muscle.  The procedure of collecting data on the TA muscle before and after experiments follows the Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles (SENIAM) recommendations.  The result of the experiment shows that there is a strong negative relationship between driver's postures in nature based on the angle of the knee with TA muscle contractions, where the Pearson correlation coefficient (r) is - .993.  While the temporal analysis measurements based on Maximum Voluntary Isometric Contraction (MVIC) 60% in a position of releasing a pedal exceeding rms µV 39.38, are 39.71 and 40.25 respectively.  On the other hand, MVIC 2% rms µV values: 1.19 and 1.2 are obtained in the position of pressing the pedal.  The knee angle with TA muscle contractions is significant [F (1, 10) = 660, p<.05] contributing 98.5% variance (R2 = .985) in the driver's posture.  A linear equations model has been developed to clearly illustrate the result.  In conclusion, when the knee angle of the driver's posture is increased, the TA muscle contraction is decreased. The increase in the knee angle will directly provide comfort to the driver while interacting with the pedal; and this is due to the reduction of TA muscle contractions.
