在超小型电动车辆中，难以令人满意地安装用于转向操作的辅助机构。为了解决这个问题，在本文中，我们提出了一种主动方向盘系统，其中方向盘和轮胎是电连接的，没有机械连接。此外，在驾驶位置受到限制的超紧凑型机动车辆中，取决于驾驶员的体格，可能发生转向负担。然而，在这种车辆中，转向反作用扭矩和转向量的影响是否增加了驾驶员的负担还没有得到澄清。因此，在这项研究中，我们开发了一个上肢负担模型，使用逆运动学和肌肉活动，调查负担的转向对司机考虑到司机的体质。
In ultra-compact electric vehicles, the satisfactory installation of an assist mechanism for steering operation is difficult. To address this problem, in this paper, we propose an active steering wheel system in which the steering wheel and tires are electrically connected, without a mechanical connection. Furthermore, in ultra-compact mobility vehicles where the driving position is restricted, steering burden is likely to occur depending on the physique of the driver. However, whether the effects of the steering reaction torque and the amount of steering increase the burden on the driver in such vehicles has not yet been clarified. Therefore, in this study, we developed an upper limb burden model using inverse kinematics and muscle activity to investigate the burden of steering on the driver by considering the driver physique.
