N2 - As a daily means of transportation, Personal Mobility (PM) attracts attention due to its high environmental performance. One of the representative PMs is Segway. However, it is expensive and unavailable to use freely on a Japanese public road because of Road Traffic Act. Therefore, our laboratory developed a one-wheel driven and standing ride type PM for the purpose of low production cost and using on the public roads freely. However, the PM has two problems; i.e., one is that its driving speed becomes uncontrollable by sunlight that changes DC offset of signals from a sensor for measuring speed, and the other is that the driver falls off by a sudden stop of the drive wheel due to battery exhaustion. In this paper, the speed control under the sun is made possible by introducing a signal conversion circuit with AC coupling. In addition, gentle decelerating and automatic stopping before the battery exhaustion prevent the driver from falling off.
