Abstract

Safe driving requires an ideal posture to bring comfort to drivers. A problem that commonly exists in driving is non-ideal driving posture, which can cause discomfort to the driver, especially when interacting with automotive pedals. Research on contraction of Soleus muscle on driver's posture based on the knee angle more than 144° in a position of pressing and releasing a pedal was conducted to investigate and overcome this problem. This is a field experimental study and surface electromyography (sEMG) is used in collecting data on the Soleus muscle. The procedure of collecting data on the Soleus muscle before and after experiments follows the Surface Electromyography for the Non-Invasive Assessment of Muscles (SENIAM) recommendations. The result from the experiment shows that there is a strong positive relationship between driver's postures in nature based upon the angle at the knee with Soleus muscle contraction, where the Pearson correlation coefficient (r) is .990. While the temporal analysis measurements based on Maximum Voluntary Isometric Contraction (MVIC) 60% in a position of pressing a pedal exceeding rms μV 25.34, and 25.47 respectively. On the other hand, MVIC 3% rms μV values: 1.18, 1.21 and 1.26 are obtained from the position of releasing the pedal. The knee angle with Soleus muscle contractions is significant [F (1, 10) = 38.06, p < .05] contributing 79.2% variance (R2 = .792) in the driver's posture. A linear equation's model has been developed to illustrate the result clearly. In conclusion, when the knee angle of the driver's posture is decreased, the Soleus muscle contraction is decreased. The decreased in the knee angle will directly provide comfort to the driver while interacting with the pedal; and this is due to the reduction of Soleus muscle contractions.
