Nowadays, ultra-compact electric vehicles are sold by several automobile's companies. Transport and Tourism, increasing the attention directed toward ultra-compact electric vehicles because of environmental issues and the aging of the society. The ultra-compact electric vehicles currently being sold are not equipped with the system for assisting the driver's steering, such as power steering. The steer-by-wire systems of interest in this study have the advantage that the steering operation of the driver can be controlled by setting the change in the reaction force actuator mounted on the steering device. There are some previous studies on the operation of the steering wheel, but the physical burden and feel of the driver in continued steering operation maintaining a constant steering angle have not been sufficiently studied. In this study, we examined by subjective evaluation and surface EMG, the muscle burden of the upper arm, which is predominantly used in the driving operation.
