One kind of autonomous vehicle that can take instructions from the driver by reading their electroencephalogram (EEG) signals using a Brain-Computer Interface (BCI) is called a Brain-Controlled Vehicle (BCV). The operation of such a vehicle is greatly affected by how well the BCI works. At present, there are limitations on the accuracy of BCI recognition, the number of distinguishable command categories, and the execution duration of command recognition. Consequently, vehicles that are exclusively controlled by EEG signals demonstrate suboptimal control performance. To address the difficulty of improving the control capabilities of brain-controlled cars while maintaining BCI performance, a fuzzy logic-based technique called as Fuzzy Brain-Control Fusion Control is introduced. This approach uses Fuzzy Discrete Event System (FDES) supervisory theory to verify the accuracy of the driver's brain-controlled directives. Concurrently, a fuzzy logic-based automatic controller is developed to generate decisions automatically in accordance with the present state of the vehicle via fuzzy reasoning. The final decision is then reached through the application of secondary fuzzy reasoning to the accuracy of the driver's instructions and the automated decisions to make adjustments that are more consistent with human intent. A clever BCI gadget known as the Consistent State Visual Evoked Potential (SSVEP) is utilized to show the viability of the proposed technique. We recommend that additional research should be conducted at this time to confirm that our recommended system may further improve the control execution of BCI-fueled cars, regardless of whether BCIs have special limitations.
一种可以通过脑机接口 (BCI) 读取驾驶员的脑电图 (EEG) 信号来接收指令的自动驾驶汽车,称为脑控车 (BCV)。这种车辆的运行受到 BCI 工作效果的极大影响。目前,BCI 识别的准确性、可区分的命令类别数量以及命令识别的执行持续时间都存在局限性。因此,完全由 EEG 信号控制的车辆表现出不佳的控制性能。为了解决在保持 BCI 性能的同时提高脑控车控制能力的困难,引入了一种基于模糊逻辑的技术,称为模糊脑控制融合控制。该方法使用模糊离散事件系统 (FDES) 监督理论来验证驾驶员脑控指令的准确性。同时,开发了一个基于模糊逻辑的自动控制器,通过模糊推理根据车辆的当前状态自动生成决策。最后,通过对驾驶员指令的准确性和自动决策的二次模糊推理应用,做出更符合人类意图的调整。一种名为一致状态视觉诱发电位 (SSVEP) 的巧妙 BCI 设备被用来展示所提出的技术的可行性。我们建议此时应进行更多的研究,以确认我们推荐的系统可以进一步提高 BCI 驱动汽车的控制执行,无论 BCI 是否存在特殊限制。
