如图4所示，本申请实施例提供了一种驾驶员驾驶行为提醒方法，该方法应用于目标车辆。该驾驶员驾驶行为提醒方法包括以下步骤：
步骤101、获取目标车辆当前的驾驶员面部信息和车辆行驶信息。
其中，车辆行驶信息包括车道偏离信息、动力装置的转速信息以及车辆加速度信息中的至少一个。
在本申请的一些实施例中，目标车辆例如可以包括中央处理器、人脸识别装置、高级驾驶辅助系统ADAS、动力管理系统和加速度传感器。
人脸识别装置用于实时采集目标车辆的驾驶员的面部信息，并将采集到的驾驶员面部信息传输至中央处理器。其中，人脸识别装置例如可以为人脸识别摄像头，通过拍摄人脸图片的方式采集驾驶员的面部信息。
ADAS用于实时获取目标车辆的车道偏离情况，并基于预设时间内目标车辆变换车道的次数生成车道偏离信息，之后将车道偏离信息传输至中央处理器。
动力管理系统用于实时采集目标车辆的动力装置的转速信息，并将采集到的转速信息传输至中央处理器。其中，动力管理系统可以包括发动机管理系统EMS和电机管理系统中的至少一项，当动力装置为发动机时，通过发动机管理系统EMS采集发动机的转速信息；当动力装置为电机时，通过电机管理系统采集电机的转速信息。
加速度传感器用于实时采集目标车辆的加速度信息，并将加速度信息传输至中央处理器。
中央处理器用于接收人脸识别装置、高级驾驶辅助系统ADAS、动力管理系统和加速度传感器分别发送的面部信息、车道偏离信息、转速信息以及加速度信息，并对这些信息进行处理。在一些实施例中，为了降低处理压力，中央处理器可以每隔设定时间对接收到的信息进行处理，例如每隔5秒进行一次处理。
步骤102、当根据获取到的驾驶员面部信息和车辆行驶信息确定驾驶员当前存在路怒驾驶行为时，发出告警信息。
在本申请的一些实施例中，目标车辆还可以包括报警装置。目标车辆的中央处理器能够根据获取到的驾驶员面部信息和车辆行驶信息判断驾驶员当前是否存在路怒驾驶行为，当确定驾驶员当前存在路怒驾驶行为时，中央处理器控制报警装置发出告警信息。
综上所述，本申请实施例提供的驾驶员驾驶行为提醒方法，通过在目标车 辆行驶过程中对驾驶员面部信息、目标车辆的连续变道情况、动力装置的转速信息以及车辆加速度信息进行检测，判断驾驶员当前是否存在因路怒导致的危险驾驶行为；当判断驾驶员存在路怒驾驶行为时，发出告警信息进行提醒，及时劝导和制止驾驶员的路怒驾驶行为。因此，本申请实施例提供的驾驶员驾驶行为提醒方法，能够及时判断驾驶员是否因路怒症产生了危险驾驶行为，并在确定存在该危险驾驶行为时，发出告警信息进行提醒，降低了危险驾驶行为系数，提高行车安全性。
在本申请的一些实施例中，目标车辆根据获取到的驾驶员面部信息和车辆行驶信息确定驾驶员当前存在路怒驾驶行为，包括：
当基于驾驶员面部信息确定驾驶员处于愤怒情绪状态，并且判断车辆行驶信息满足以下评价条件中的至少一项时，确定驾驶员当前存在路怒驾驶行为：
基于驾驶员面部信息确定驾驶员处于愤怒情绪状态；
基于车道偏离信息确定目标车辆存在连续变道行为；
基于动力装置的转速信息确定动力装置处于高转速区间；以及，
基于车辆加速度信息检测到目标车辆交替出现急加速和急减速工况。
其中，中央处理器在接收到人脸识别装置发送的驾驶员面部信息之后，可以识别该面部信息对应的情绪状态。例如，当中央处理器接收到人脸识别装置发送的人脸图片后，识别出当前的人脸图片中的情绪为愤怒情绪或者暴躁情绪，并且当前的人脸图片中的情绪与上一秒接收到的人脸图片中的情绪不同(即上一秒接收到的人脸图片中的情绪不是愤怒情绪或者暴躁情绪)时，确定当前该面部信息对应的情绪状态为愤怒状态。愤怒情绪状态下驾驶员容易做出冲动性行为，因此识别驾驶员的情绪状态可以作为识别是否为路怒症的必要条件。可选地，目标车辆中可以存储有情绪识别训练模型，该情绪识别训练模型是基于多张愤怒情绪或者暴躁情绪的照片进行学习和训练得到的，中央处理器可以通过该情绪识别训练模型识别人脸照片中的情绪。
中央处理器在接收到ADAS发送的车道偏离信息之后，从中读取目标车辆在预设时间内变换车道的次数，当检测到目标车辆出现高频变道情况时，确定目 标车辆正在进行连续变道行为，可能是在与其他车辆追逐并相互别车。因此检测目标车辆的车道变换情况可以作为其中一项评价条件。
中央处理器在接收到动力管理系统发送的动力装置的转速信息之后，判断动力装置当前的转速是否处于高转速区间。例如，当动力装置为发动机时，若检测到当前时刻起500ms时间内发动机的转速超过3000rpm时，则发动机当前的转速处于高转速区间。其中，动力装置对应的高转速区间可以根据实际情况进行设定。当动力装置处于高转速区间时，目标车辆可能是在进行加速超车行为。因此检测目标车辆的动力装置的转速可以作为其中一项评价条件。
中央处理器在接收到加速度传感器采集的加速度信息之后，判断车辆是否存在交替出现的急加速和急减速工况，当检测到目标车辆存在急减速、急加速再急减速的连续变化时，目标车辆很可能在与其他车辆相互超车和别车。因此车辆加速度的连续变化可以作为其中一项评价条件。
在确定驾驶员处于愤怒情绪状态之后，对于获取到的车辆行驶信息，还要基于上述至少一项评价条件，判断目标车辆的驾驶员当前是否存在路怒驾驶行为，若满足任一评价条件，则确认存在路怒驾驶行为，中央处理器可以控制报警装置发出告警信息。
在本申请的一些实施例中，为了提高判断路怒驾驶行为的准确性，还可以在同时满足上述三个评价条件之后，确定目标车辆的驾驶员存在因路怒导致的危险驾驶行为。
可选地，目标车辆还包括自动变速箱控制单元TCU模块。在根据获取到的驾驶信息确定驾驶员存在路怒驾驶行为之后，还可以在报警装置发出告警信息的同时，通过TCU模块强行控制目标车辆减速行驶，从而降低行车风险。
可选地，在本申请实施例提供的驾驶员驾驶行为提醒方法中，继续参见图4，在步骤102之后，该方法还可以包括步骤103-105。
步骤103、重复判断驾驶员是否处于愤怒情绪状态，以及车辆行驶信息是否满足评价条件中的至少一项。
在步骤102中，当目标车辆的中央处理器基于驾驶员面部信息判断驾驶员 正处于愤怒情绪状态，并且基于车辆行驶条件判断满足评价条件的至少一项时，则确定驾驶员当前正在进行路怒驾驶行为，需要发出告警信息进行提醒。步骤103是在报警装置发出告警信息之后的监督步骤，用于监督驾驶员是否已经停止了路怒驾驶行为。
通常情况下，当目标车辆发出告警信息之后，驾驶员会及时调节自己的情绪，并且停止路怒驾驶行为，此时跳过步骤104，直接执行步骤105即可。
但是也存在一些特殊情况，即当目标车辆发出告警信息之后，驾驶员无法及时调节情绪，仍在进行路怒驾驶行为。此时，目标车辆会主动采取限制措施，即执行步骤104。
步骤104、当连续至少两次判断出驾驶员处于愤怒情绪状态，且车辆行驶信息满足评价条件中的至少一项时，控制目标车辆减速行驶。
在一些实施例中，目标车辆会周期性地检测当前是否存在路怒驾驶行为，例如中央处理器会每隔5秒进行一次判断。当然，目标车辆也可以非周期性地检测，例如若当前不存在路怒驾驶行为，则下一次的检测时间为20秒后，若当前存在路怒驾驶行为，则下一次的检测时间为5秒后。
当目标车辆连续至少两次判断出驾驶员处于愤怒情绪状态，且车辆行驶信息满足评价条件中的至少一项时，中央处理器向TCU模块发送指令，控制目标车辆减速行驶。在另一些实施例中，也可以根据实际需要适当延长或者缩短留给驾驶员的反应时间，例如也可以在目标车辆连续三次判断出驾驶信息满足评价条件中的至少一项时，中央处理器通过TCU模块控制目标车辆减速行驶。
步骤105、当根据驾驶员面部信息判断驾驶员没有处于愤怒情绪状态，并且车辆行驶信息中的每一项都不满足对应的评价条件时，确定驾驶员当前已停止路怒驾驶行为，控制目标车辆停止发出告警信息。
当中央处理器基于人脸识别装置、高级驾驶辅助系统ADAS、动力管理系统和加速度传感器分别获取的驾驶员面部信息、车道偏离信息、动力装置的转速信息以及车辆加速度信息，判断驾驶员未处于愤怒情绪状态，车辆没有连续变道，动力装置的转速未处于高转速区间，并且车辆没有交替出现急加速和急减 速工况时，确定驾驶员当前已经停止了因路怒导致的危险驾驶行为，此时中央处理器控制报警装置停止发出告警信息。
可选地，本申请实施例中的告警信息可以包括第一提示信息，第一提示信息用于提示驾驶员停止路怒驾驶行为。其中，第一提醒信息包括文字提醒信息、语音提醒信息和灯光提醒信息中的至少一种。报警装置例如可以包括报警仪表，中央处理器可以控制报警仪表弹出文字提醒，从而进行提示。报警装置也可以包括扬声器，中央处理器通过控制扬声器发出语音提醒，从而进行提示。报警装置还可以包括灯光控制器，中央处理器通过控制灯光控制器打开目标车辆的内饰灯，从而进行提示。
可选地，本申请实施例中的告警信息还可以包括第二提醒信息，第二提醒信息用于提醒目标车辆周围的其他车辆避让目标车辆。其中，第二提醒信息包括文字提醒信息、语音提醒信息和灯光提醒信息中的至少一种。报警装置例如可以包括车外显示器，中央处理器可以控制车外显示器显示提醒文字，从而进行提示。报警装置也可以包括车外扬声器或者喇叭，中央处理器通过控制车外扬声器发出语音提醒，或者控制喇叭鸣笛，从而进行提示。报警装置还可以包括灯光控制器，中央处理器通过控制灯光控制器打开目标车辆双闪灯，从而进行提示。
综上所述，本申请实施例提供的驾驶员驾驶行为提醒方法，通过在目标车辆行驶过程中对驾驶员的面部信息、目标车辆的连续变道情况、动力装置的转速信息以及车辆加速度信息进行检测，判断驾驶员当前是否存在因路怒导致的危险驾驶行为；当判断驾驶员存在路怒驾驶行为时，发出告警信息进行提醒，及时劝导和制止驾驶员的路怒驾驶行为；若驾驶员及时停止路怒驾驶行为，则停止发出告警信息；若驾驶员没有及时停止路怒驾驶行为，可以通过TCU模块强行控制车辆减速，以保证驾驶安全。因此，本申请实施例提供的驾驶员驾驶行为提醒方法，能够及时判断驾驶员是否因路怒症产生了危险驾驶行为，并在确定存在该危险驾驶行为时，发出告警信息进行提醒，并在驾驶员未听从劝告时强行控制目标车辆减速，从而降低了危险驾驶行为系数，提高行车安全性。
