The invention discloses a driving style determination method and device, a vehicle and a storage medium. The method comprises the following steps: acquiring a kinematic fragment according to vehicle driving data, and acquiring a first characteristic parameter representing a transverse driving style and a second characteristic parameter representing a longitudinal driving style in the kinematic fragment; performing dimension reduction processing on the first feature parameter and the second feature parameter to obtain a plurality of principal component score matrixes; and clustering the kinematics fragments according to each principal component score matrix to obtain a plurality of clustering centers, and determining the driving styles of the driver when the vehicle turns, accelerates or decelerates according to the characteristic parameters corresponding to each clustering center. According to the embodiment of the invention, the parameters corresponding to the transverse driving style and the longitudinal driving style are determined from the kinematic fragments, and the kinematic fragments are clustered by using the principal component score matrix, so that the driving styles of the driver in different dimensions are determined, and the intelligence of vehicle driving style judgment is improved.
本发明公开了一种驾驶风格确定方法、装置、车辆及存储介质。该方法包括:根据车辆行驶数据获取运动学片段,获取运动学片段中表征横向驾驶风格的第一特征参数和表征纵向驾驶风格的第二特征参数;对第一特征参数和第二特征参数分别进行降维处理,得到多个主成分得分矩阵;根据每个主成分得分矩阵对运动学片段进行聚类,得到多个聚类中心,根据每个聚类中心对应的特征参数确定驾驶员分别在车辆转向、加速或减速时的驾驶风格。本实施例通过从运动学片段确定横向驾驶风格和纵向驾驶风格分别对应的参数,并利用主成分得分矩阵对运动学片段进行聚类,从而确定驾驶员在不同维度的驾驶风格,提高了对于车辆驾驶风格判断的智能化。
