Abstract

In this paper, correlation between surface Electromyogram (EMG) signal and lateral acceleration of the car was studied to examine the possibility of EMG as an indicator of ride comfort. The EMG measuring experiments are conducted with a normal car and its modified car. Two different cars make a driving slalom in the test course, and a subject sat in a rear seat. Surface EMG signals of Sternocleidomastoid muscles on both sides of the neck are measured. It is found that the values of EMG signals of opposite sides to the direction of car acceleration are growing. In addition, the results show a tendency that root mean square (RMS) value of EMG gets smaller when the acceleration is smaller.
