The invention relates to a hybrid electric vehicle driving style recognition method and system. The method comprises the following steps that the impact degree at the current moment is calculated based on the current vehicle speed, the impact degrees at all moments in a recognition period corresponding to the current moment are obtained, and the impact degree standard deviation at the current moment is calculated based on the impact degrees in the recognition period; acquiring a real-time working condition type, and determining a working condition absolute average impact degree based on the real-time working condition type; a driving style coefficient is calculated based on the impact degree standard deviation and the working condition absolute average impact degree, the driving style types are determined according to the driving style coefficient, and the driving styles are divided into the calm type, the standard type and the aggressive type. Compared with the prior art, on one hand, the current working condition type is introduced to assist in driving style recognition, and on the other hand, the driving style recognition is performed by using the standard deviation of the impact degree in the recognition period, so that the driving style type can be recognized according to the vehicle driving information by taking the impact degree as a recognition basis, and accurate and rapid recognition of the driving style is completed.

    本发明涉及一种混合动力汽车驾驶风格识别方法及系统,方法包括以下步骤:基于当前车速计算当前时刻的冲击度,获取当前时刻对应的识别周期内各个时刻的冲击度,基于识别周期内冲击度计算当前时刻的冲击度标准差;获取实时工况类型,基于实时工况类型确定工况绝对平均冲击度;基于冲击度标准差和工况绝对平均冲击度计算驾驶风格系数,根据驾驶风格系数确定驾驶风格类型,驾驶风格分为平静型、标准型和激进型。与现有技术相比,本发明一方面引入当前工况类型辅助驾驶风格识别,另一方面,使用了识别周期内冲击度的标准差进行驾驶风格识别,从而可以以冲击度为识别依据,根据车辆行驶信息识别出驾驶风格类型,完成驾驶风格的精确、快速识别。
