本研究旨在开发一种基于共享控制的转向辅助系统与防御性制动控制一起，以实现安全裕度形成潜在的风险，并在同一驾驶操作中与专家驾驶员一起稳定地操作转向。所提出的系统的主要特点是通过在风险预测制动控制的条件下使用共享比（SR）的关键概念来指示与触觉转向控制扭矩的参考转向角。为了研究所提出的系统的有效性，在一个停车超车的情况下，使用测试车辆进行了实验。以32名老年驾驶员为研究对象，对老年驾驶员的操纵特性变化进行了评价。从评估，积极的共享控制特性被确认的条件下，SR= 0.5（软）控制。
This study aims to develop a shared control based steering assistance system together with a defensive brake control in order to achieve safety margin form a potential risk, and operate a steering with stable manner in same driving maneuver with an expert driver. The key feature of the proposed system is to indicate a reference steering angle with the haptic steering control torque by using the key concept of the shared ratio (SR) in the condition of risk predictive brake control. To investigate the effectiveness of the proposed system, the experiment in a parked vehicle overtaking scenario was conducted by using the test vehicle. Thirty-two elderly drivers were employed, and the changes of the maneuver characteristics were evaluated. From the evaluations, the positive shared control characteristics are confirmed in the condition of with SR= 0.5 (soft) control.
