The invention provides a driving tendency dynamic transition probability calculation method considering pessimistic emotions. The method comprises the steps: acquiring driving behavior data and driverphysiological data, and extracting feature parameters; quantitatively representing the driving tendency under the normal emotion and the pessimistic emotion; respectively calculating driving tendencyquantized values under the normal emotion and the pessimistic emotion according to the characteristic parameter data; judging the driving tendency of the driver according to the driving tendency quantized value of the driver; and comparing driving tendency categories under the two emotions and calculating the driving tendency dynamic transition probability. According to the driving tendency dynamic transition probability calculation method under the influence of the pessimistic emotion, the driving tendency transition rule of the driver is explored and the improvement of an automobile auxiliary driving system is facilitated, so that the active safety of the automobile is further improved.
本发明提供一种考虑悲伤情绪的驾驶倾向性动态转移概率计算方法,方法包括:获取驾驶行为数据与驾驶员生理数据并提取特征参数;定量表示正常情绪与悲伤情绪下的驾驶倾向性;根据特征参数数据分别计算正常情绪与悲伤情绪下驾驶倾向性量化值;依据驾驶员驾驶倾向性量化值判定其驾驶倾向性;对比两种情绪下驾驶倾向性类别并计算驾驶倾向性动态转移概率。本发明给出了悲伤情绪影响下驾驶员驾驶倾向性动态转移概率计算方法,探寻驾驶员驾驶倾向性转移规律,有助于汽车辅助驾驶系统的完善,进一步提升汽车主动安全。
