This paper proposes a semi-autonomous collision avoidance system for the prevention of collisions between vehicles and pedestrians and objects on a road. The system is designed to be compatible with the human-centered automation principle, i.e., the decision to perform a maneuver to avoid a collision is made by the driver. However, the system is partly autonomous in that it turns the steering wheel independently when the driver only applies the brake, indicating his or her intent to avoid the obstacle. With a medium-fidelity driving simulator, we conducted an experiment to investigate the effectiveness of this system for improving safety in emergency situations, as well as its acceptance by drivers. The results indicate that the system effectively improves safety in emergency situations, and the semi-autonomous characteristic of the system was found to be acceptable to drivers.
本文提出了一种半自主式避撞系统，用于预防车辆与行人及道路上物体发生碰撞。该系统的设计符合以人为中心的自动化原则，即执行避撞操作的决策由驾驶员做出。然而，该系统在部分程度上是自主的，因为当驾驶员仅踩下刹车而没有转动方向盘时，系统会自动转动方向盘，表明驾驶员意图避开障碍物。我们使用中保真度驾驶模拟器进行了一项实验，以研究该系统在改善紧急情况下的安全性方面的有效性，以及驾驶员对该系统的接受程度。结果表明，该系统能有效提高紧急情况下的安全性，并且该系统的半自主特性被发现能被驾驶员接受。
