通过触觉反馈增强的车门虚拟原型是减少物理原型数量的一种有前途的方法。我们澄清、纠正、总结和扩展了我们之前在车门触觉模拟方面的工作。一个基本问题是推导任务优化的触觉界面的性能规范，该规范基于典型用户与车门交互的知识以及旋转车门动力学的综合模型。我们认为必须使用具有高扭矩输出（≥ 100 N·m）和高控制带宽的直接驱动器。因此，我们创建了一种无间隙、非常坚硬的设备，提供安全且高保真的触觉渲染。最后，我们对 17 名参与者进行了广泛的用户研究。一个重要的结果是，如果不同的门概念之间的差异大于 5 N·m，则触觉模拟可以可靠地用于评估它们。此外，参与者不喜欢关门时用力过大，而低力和中等力都值得赞赏。这与汽车行业的启发式发现一致，这表明了我们虚拟原型方法的有效性。
Virtual prototyping of car doors enhanced with haptic feedback is a promising way to decrease the number of physical prototypes. We clarify, correct, summarize, and extend our previous work on the haptic simulation of car doors. A fundamental issue is the derivation of the performance specification of a task-optimized haptic interface, which is based on the knowledge of the typical user interaction with a car door and a comprehensive model of the dynamics of a rotatory car door. We reason that a direct drive with a high torque output (≥ 100 N·m) and a high control bandwidth has to be used. Consequently, we created a backlash-free very stiff device providing a safe and high-fidelity haptic rendering. Finally, we conducted an extensive user study with 17 participants. An important result is that the haptic simulation can be reliably used to evaluate different door concepts if the difference between them is larger than 5 N·m. Furthermore, the participants did not like a high effort for closing the door, while both a low and a medium effort are appreciated. This is in accordance with the heuristic findings of the automotive industry, which shows the effectiveness of our virtual prototyping approach.
