摘要

本研究利用稳态视觉诱发电位（SSVEP）接口和概率支持向量机（SVM）增强了脑控车辆（BCV）的横向控制。滤波器组 CSP（FBCSP）算法改进了脑信号解码，而乙叉拟合 SVM（SF-SVM）则通过概率指令实现了更平滑的控制。在线测试的分类准确率达到 84.03%。在车道保持任务中，SF-SVM 比标准 SVM 提高了 20% 以上的完成率，减少了脑电图的非稳态效应。概率模型优化了连续控制，显著提高了 BCV 性能。

Lateral control of brain-controlled vehicle based on SVM probability output model.

This study enhances brain-controlled vehicle (BCV) lateral control using a steady-state visual evoked potential (SSVEP) interface and probabilistic support vector machine (SVM). A filter bank CSP (FBCSP) algorithm improves brain signal decoding, while a sigmoid-fitted SVM (SF-SVM) enables smoother control through probabilistic commands. Online tests achieved 84.03% classification accuracy. In lane-keeping tasks, SF-SVM improved completion rates by over 20% compared to standard SVM, reducing EEG non-stationarity effects. The probabilistic model optimized continuous control, significantly enhancing BCV performance.
