Recently more and more small-sized vehicles like a personal vehicle have been developed. As the mass of small-sized vehicle is similar to that of driver, coupling motion between them is increasing compared with traditional type of vehicle. Therefore, it is necessary for developing small-sized vehicle to give ample consideration to the dynamics of the human body riding on a vehicle. In this research, model of the human body ridding on a vehicle is proposed. But whole body model is multiple degrees of freedom and obscurity phenomenon. Furthermore, the influence of parameters of human motion is uncertainty and it is difficult to set parameters. Therefore, in this research, human model is treated as only trunk of the human body riding on a vehicle. Then the numerical simulation is shown under the condition when lateral acceleration applied. Moreover the influence of parameter of human behavior is considered.
