Ultra-compact electric mobility vehicle is a vehicle with a short wheelbase and has a small turning radius. It has become widespread in situations such as transportation for narrow roads area and car-sharing services, and all kind of people use it. Therefore, the ultra-compact electric mobility vehicle requires a steering system that enables easy and safe driving regardless of age, physique, or driving skill. In our laboratory, we consider that the steering feel and burden are different each of driver, and we have suggested an active steering wheel system that can quantitatively evaluate each driver's steering feeling and burden by using biological information and provide steering support to each. The driver's arm model by inverse kinematics used in robotics was used to calculate the joint moment and measure the muscle activity for the steering burden evaluation, and the fundamental consideration of steering burden evaluation by the steering reaction torque was conducted.
