中文摘要:
以实验采集的起步工况驾驶数据为基础,利用PCA分析筛选出驾驶员在起步工况下的风格特征参数,采用GMM聚类算法对起步工况下的驾驶数据进行分析.以驾驶风格聚类分析结果为基础建立了基于Fisher判别的驾驶风格识别方法模型,运用经典和改进Fisher判别对驾驶风格数据的测试集进行识别.结果表明,改进Fisher判别的识别正确率可达85%以上,证明了改进Fisher判别在处理驾驶风格会影响车辆的多种性能表现时有效,具有较高的准确性.
English Summary:
According as the driving data of the vehicle starting condition collected from experiments, the driving style characteristic parameters were selected based on principal component analysis (PCA) method. Then, clustering and analyzing the driving data with Gaussian mixture mode (GMM) clustering algorithm, a driving style recognizer was developed based on Fisher discrimination. Finally, the classical Fisher discrimination and the modified Fisher discrimination were utilized to identify the test set of driving style data comparatively. The results show that, the recognition accuracy with modified Fisher discrimination can reach more than 85%, proving the availability and veracity of this modified Fisher discrimination in the estimation of driving style and vehicle moving performance.
