Steering wheels and joysticks are presently the most familiar tools for vehicular operations.However, it may become difficult for them to meet special demands, such as those associated withdriving in a narrow-and-small capsule, or rapid-responding steering used in entertainment, or bythe military. In this study, based on the signals of center of gravity (COG) from the driver’s seat, anovel vehicular control method is proposed and developed. In this research, a tricycle system withtwo front wheels and one rear wheel (2F/1R) was designed and set up to simulate the conventionalsteering mechanism in ships or airplanes. The system primarily consists of a wheel motor, a dcmotor and a pilot’s seat. They are designed to be a main mover, a steering , and a controller,respectively. In addition, the angles of the slope of the pilot’s seat as detected by tilts are used asthe displacement signals. The results show that the mean absolute percentage error between thesimulation and the experimental studies is smaller than 1.05%. The effectiveness of this proposeddesign is confirmed.
