下面结合附图，对本发明的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
本发明实施例提供一种转向灯的控制方法。图1为本发明实施例提供的转向灯的控制方法的流程图。如图1所示，本实施例中的方法，可以包括：
步骤S101、在车辆的转向灯开启后，检测所述车辆方向盘的状态。
如图2所示，车辆20行驶在车道上，车辆20可以是自动驾驶车辆，也可以是司机驾驶车辆，此处不做具体限定。本实施例以司机驾驶车辆为例，车辆20中设置有用于控制转向灯的控制装置，该控制装置可用于在车辆20完成转向或变道后自动关闭转向灯，本实施例不限定该控制装置在车辆中的安装位置，例如可以设置在该车辆方向盘中。假设在t1时刻，车辆20行驶在左侧车道，车辆20的转向灯未开启，此时，转向灯回正机构例如图2所示的转向灯杆10处于初始状态，在t1时刻之后的t2时刻，车辆20的转向灯开启，若该车辆20的右转向灯开启，则该转向灯杆10处于如图3所示的状态，即转向灯杆10垂直伸出；若该车辆20的左转向灯开启，则该转向灯杆处于如图4所示的状态，即转向灯杆10向斜下方伸出。
可选的，该控制装置包括转向灯状态检测电路，或者，该控制装置与该转向灯状态检测电路电连接，该控制装置可通过该转向灯状态检测电路，实时检测该转向灯的状态，若该控制装置检测到车辆20的转向灯例如右转向灯开启，则该控制装置立即检测该车辆20方向盘的状态。
步骤S102、如果所述方向盘处于回正状态，且持续第一预设时间，则判断所述转向灯是否处于开启状态。
如图5所示，假设该控制装置在t2时刻检测到车辆20的右转向灯开启，并在t2时刻立即检测方向盘的状态,若方向盘处于回正状态，则从t2时刻开始检测该方向盘保持回正状态的时间，若从t2时刻开始持续第一预设时间直到t3时刻，该方向盘依然处于回正状态，则在t3时刻检测车辆20的右转向灯是否处于开启状态。
步骤S103、若所述转向灯处于开启状态，则关闭所述转向灯。
若在t3时刻该车辆20的右转向灯还处于开启状态，则说明驾驶员在t2时刻开启右转向灯后的第一预设时间内可能一直没有变道或转向,如图5所示，此时，该控制装置控制该右转向灯关闭。
在其他实施例中,在车辆的转向灯开启后，检测所述车辆方向盘的状态的另一种可能情况是:在车辆的转向灯开启后的阈值时间检测所述车辆方向盘的状态,如图6所示,该控制装置在t2时刻检测到车辆20的右转向灯开启，在t2时刻之后的阈值时间例如t3时刻检测方向盘的状态。而在 t2时刻到t3时刻之间，该车辆20已经发生了变道。如果t3时刻方向盘处于回正状态，且持续第一预设时间，例如直到t4时刻该方向盘依然处于回正状态，则在t4时刻判断右转向灯是否处于开启状态，如果该右转向灯还处于开启状态，说明车辆20在完成变道后没有关闭右转向灯，此时，该控制装置控制该右转向灯关闭。
可选的，所述关闭所述转向灯，包括：向所述车辆方向盘中的驱动马达发送控制指令，以使所述驱动马达根据所述控制指令控制转向灯回正机构回正。
如图7所示，在本实施例中，车辆方向盘71中安装有驱动马达72，当该控制装置控制转向灯例如右转向灯关闭时，该控制装置向该驱动马达72发送控制指令，该驱动马达72根据该控制指令带动该方向盘71中时钟弹簧上的凸台73将垂直伸出的转向灯杆10推回，从而使得转向灯杆10变回到初始状态，即关闭右转向灯。
另外，该控制装置控制左转向灯关闭的原理和方法与此类似，此处不再赘述。
本实施例通过在车辆的转向灯开启后，检测车辆方向盘的状态，如果方向盘处于回正状态，且持续第一预设时间，进一步判断转向灯是否处于开启状态，如果转向灯处于开启状态，说明该车辆开启转向灯后一直未变道或转向，也没有关闭转向灯；或者完成了变道或转向后未关闭转向灯，此时关闭该转向灯，从而使得该方向盘不需要转动较大的角度，也可以控制转向灯回位，解决了方向盘转动角度不够大无法使转向灯回位的问题。
本发明实施例提供一种转向灯的控制方法。图8为本发明另一实施例提供的转向灯的控制方法的流程图。如图8所示，在图1所示实施例的基础上，本实施例中的方法，可以包括：
步骤S801、在车辆的转向灯开启后，检测所述车辆方向盘的状态。
步骤S801与步骤S101的具体原理和实现方式一致，此处不再赘述。
步骤S802、若所述方向盘向第一转动方向转动，则在转动后的第二预设时间，检测所述方向盘是否回正。
如图6所示，假设该控制装置在t2时刻检测到车辆20的右转向灯开 启，并在t2时刻立即检测方向盘的状态，若在t2时刻方向盘向第一转动方向例如向右转动，则在转动后的第二预设时间例如t3时刻检测该方向盘是否回正。
步骤S803、如果所述方向盘处于回正状态，且持续第一预设时间，则判断所述转向灯是否处于开启状态。
步骤S804、若所述转向灯处于开启状态，则关闭所述转向灯。
如果在t3时刻方向盘处于回正状态，且持续第一预设时间，例如直到t4时刻该方向盘依然处于回正状态，则在t4时刻判断右转向灯是否处于开启状态，如果该右转向灯还处于开启状态，说明车辆20在完成变道后没有关闭右转向灯，此时，该控制装置控制该右转向灯关闭。本实施例通过在车辆的转向灯开启后，检测车辆方向盘的状态，若方向盘向第一转动方向转动，则在转动后的第二预设时间，检测所述方向盘是否回正，如果方向盘处于回正状态，且持续第一预设时间，进一步判断转向灯是否处于开启状态，如果转向灯处于开启状态，说明该车辆向第一转动方向转向后未关闭转向灯，此时关闭该转向灯，从而使得该方向盘不需要转动较大的角度，也可以控制转向灯回位，解决了方向盘转动角度不够大无法使转向灯回位的问题。
本发明实施例提供一种转向灯的控制方法。图9为本发明另一实施例提供的转向灯的控制方法的流程图。如图9所示，在图1所示实施例的基础上，本实施例中的方法，可以包括：
步骤S901、在车辆的转向灯开启后，检测所述车辆方向盘的状态。
步骤S901与步骤S101的具体原理和实现方式一致，此处不再赘述。
步骤S902、若所述方向盘向第一转动方向转动后又向第二转动方向转动，则在所述方向盘向第二转动方向转动后的第二预设时间，检测所述方向盘是否回正。
其中，所述第一转动方向和所述第二转动方向相反。
如图10所示，假设该控制装置在t2时刻检测到车辆20的右转向灯开启，并在t2时刻之后的t3时刻检测方向盘的状态，若在t3时刻方向盘向第一转动方向例如向右转动，在t4时刻又向该第一转动方向的相反 方向例如左转动，则在该方向盘向左转动后的第二预设时间例如t5时刻检测该方向盘是否回正。其中，该第一转动方向的相反方向记为第二转动方向。
在其他实施例中，所述若所述方向盘向第一转动方向转动后又向第二转动方向转动，则在所述方向盘向第二转动方向转动后的第二预设时间，检测所述方向盘是否回正，包括：若所述方向盘向第一转动方向转动后又向第二转动方向转动，则检测所述方向盘向第二转动方向转动的角度；若所述角度小于预设角度，则在所述方向盘向第二转动方向转动后的第二预设时间，检测所述方向盘是否回正。
如图10所示，假设该控制装置在t2时刻检测到车辆20的右转向灯开启，并在t2时刻之后的t3时刻检测方向盘的状态，若在t3时刻方向盘向第一转动方向例如向右转动，在t4时刻又向该第一转动方向的相反方向例如左转动，则检测该方向盘向左转动的角度，若该角度小于预设角度，也就是说，该方向盘向左转动的角度较小，则在该方向盘向左转动后的第二预设时间例如t5时刻检测该方向盘是否回正。
步骤S903、如果所述方向盘处于回正状态，且持续第一预设时间，则判断所述转向灯是否处于开启状态。
步骤S904、若所述转向灯处于开启状态，则关闭所述转向灯。
如果在t5时刻方向盘处于回正状态，且持续第一预设时间，则进一步判断该右转向灯是否处于开启状态，若该右转向灯还处于开启状态，说明车辆20在完成变道后没有关闭右转向灯，此时，该控制装置控制该右转向灯关闭。
另外，本实施例所述的方法也适用于方向盘先向左转动后向右转动并回正的场景，具体原理与本实施例所述方法一致，此处不再赘述。
本实施例通过在车辆的转向灯开启后，检测车辆方向盘的状态，若方向盘向第一转动方向转动后又向第二转动方向转动，且该方向盘向第二转动方向转动的角度较小，则在向第二转动方向转动后的第二预设时间，检测所述方向盘是否回正，如果方向盘处于回正状态，且持续第一预设时间，进一步判断转向灯是否处于开启状态，如果转向灯处于开启状态，说明该车辆向第一转动方向转向且回正后未关闭转向灯，此时关闭该转向灯，从 而使得该方向盘不需要转动较大的角度，也可以控制转向灯回位，解决了方向盘转动角度不够大无法使转向灯回位的问题。
本发明实施例提供一种转向灯的控制方法。图11为本发明另一实施例提供的转向灯的控制方法的流程图。如图11所示，在上述实施例如图1所示实施例的基础上，本实施例中的方法，可以包括：
步骤S1101、在车辆的转向灯开启后，检测所述车辆方向盘的状态。
步骤S1101与步骤S101的具体原理和实现方式一致，此处不再赘述。
步骤S1102、检测所述车辆是否行驶在高速公路上。
在本实施例中，若车辆20行驶在高速公路上，则车辆20变道及回正时方向盘的转动角度较小。为了能够在该方向盘转动较小的角度时，该控制装置依然可以准确控制转向灯回位，该控制装置还可以检测该车辆20是否行驶在高速公路上。
可选的，所述检测所述车辆是否行驶在高速公路上，包括如下几种可行的实现方式：
一种可行的实现方式是：获取所述车辆的行驶速度；若所述车辆的行驶速度大于预设速度，则确定所述车辆行驶在高速公路上。
例如，该控制装置可实时获取该车辆20中的速度传感器检测到的该车辆20的行驶速度，当该车辆20的行驶速度大于预设速度例如60km/h时，该控制装置确定该车辆20行驶在高速公路上。
另一种可行的实现方式是：获取所述车辆上设置的视觉传感器检测的所述车辆所在车道的图像信息；若所述图像信息包括高速公路标识，则确定所述车辆行驶在高速公路上。
例如，车辆20还可以设置有视觉传感器，该视觉传感器具体可以是拍摄设备，该拍摄设备用于实时采集车辆20周围环境的图像信息，该控制装置通过该拍摄设备获取该图像信息，并根据该图像信息确定车辆20所在车道周围是否存在高速公路标识，若该图像信息中存在高速公路标识，则该控制装置确定该车辆20行驶在高速公路上。
再一种可行的实现方式是：获取所述车辆的行驶速度；获取所述车辆上设置的视觉传感器检测的所述车辆所在车道的图像信息；若所述车辆的 行驶速度大于预设速度，且所述图像信息包括高速公路标识，则确定所述车辆行驶在高速公路上。
例如，该控制装置可实时获取该车辆20中的速度传感器检测到的该车辆20的行驶速度，并通过该车辆20中设置的拍摄设备获取车辆20周围环境的图像信息，进一步，该控制装置检测该车辆20的行驶速度是否大于预设速度，以及该图像信息中是否存在高速公路标识，若该车辆20的行驶速度大于预设速度例如60km/h，且若该图像信息中存在高速公路标识，则该控制装置确定该车辆20行驶在高速公路上。
步骤S1103、如果所述车辆行驶在高速公路上，所述方向盘处于回正状态，且持续第一预设时间，则判断所述转向灯是否处于开启状态。
如图6所示，如果车辆20行驶在高速公路上，该控制装置在t2时刻检测到车辆20的右转向灯开启，在t2时刻之后的阈值时间例如t3时刻检测方向盘的状态。而在t2时刻到t3时刻之间，该车辆20已经发生了变道。如果t3时刻方向盘处于回正状态，且持续第一预设时间，例如直到t4时刻该方向盘依然处于回正状态，则在t4时刻判断右转向灯是否处于开启状态。
步骤S1104、若所述转向灯处于开启状态，则关闭所述转向灯。
如果在t4时刻该右转向灯还处于开启状态，说明车辆20在完成变道后没有关闭右转向灯，此时，该控制装置控制该右转向灯关闭。
可选的，所述若所述转向灯处于开启状态，则关闭所述转向灯，包括：若所述转向灯处于开启状态，则检测所述车辆是否行驶在车道内；若所述车辆行驶在车道内，则关闭所述转向灯。
例如，在t4时刻该右转向灯还处于开启状态，则进一步检测该车辆20是否行驶在车道内，从而确保该车辆20是否真的完成了变道，如果该控制装置在t4时刻检测到该车辆20处于行驶在车道内，说明该车辆20已经完成了变道且变道后未关闭转向灯，此时，该控制装置控制该右转向灯关闭。
具体的，所述检测所述车辆是否行驶在车道内，包括：获取所述车辆上设置的视觉传感器检测的所述车辆所在车道的图像信息；根据所述图像信息，检测所述车辆是否行驶在车道内。
例如，该控制装置通过该车辆20中设置的拍摄设备获取车辆20周围环境的图像信息，并根据该图像信息中车辆20所在车道的车道边界、车道线等，确定车辆20是否在车道内且未碾压车道边界或车道线，如果该控制装置根据该图像信息确定该车辆20的车轮没有碾压车道边界或车道线，且车道边界或车道线在该车轮周围预设距离范围内，则确定该车辆20行驶在车道内。
在一些实施例中，所述如果所述方向盘处于回正状态，且持续第一预设时间，则判断所述转向灯是否处于开启状态，包括：如果所述车辆速度大于预设速度阈值，所述方向盘处于回正状态，且持续第一预设时间，则判断所述转向灯是否处于开启状态。
如图6所示，假设该控制装置在t2时刻检测到车辆20的右转向灯开启，并在t2时刻立即检测方向盘的状态，若在t2时刻方向盘向第一转动方向例如向右转动，则在转动后的第二预设时间例如t3时刻检测该方向盘是否回正。如果车辆20的行驶速度比较快例如大于预设速度阈值，则在t2时刻方向盘向右转动时不需要转动较大的角度就可以完成变道，同样，车辆20驶入右侧车道后，方向盘不需要向左转动较大角度即可将该方向盘回正。因此，如果车辆20的行驶速度大于预设速度阈值，且在t3时刻方向盘处于回正状态，并持续第一预设时间，例如直到t4时刻该方向盘依然处于回正状态，则在t4时刻判断右转向灯是否处于开启状态，如果该右转向灯还处于开启状态，说明车辆20以较高的行驶速度完成变道后没有关闭右转向灯，此时，该控制装置控制该右转向灯关闭。
本实施例通过确定车辆行驶在高速公路上，在车辆的转向灯开启后，检测车辆方向盘的状态，如果方向盘处于回正状态，且持续第一预设时间，进一步判断转向灯是否处于开启状态，如果转向灯处于开启状态，说明该车辆开启转向灯后一直未变道或转向，也没有关闭转向灯；或者完成了变道或转向后未关闭转向灯，此时关闭该转向灯，从而使得行驶在高速公路上车辆的方向盘不需要转动较大的角度，也可以控制转向灯回位，解决了方向盘转动角度不够大无法使转向灯回位的问题；另外，在转向灯处于开启状态时，通过视觉传感器检测该车辆是否在行驶车道内，即结合方向盘的转向和视觉传感器以准确判断该车辆是否已经完成转向或变道，从而提 高了对该转向灯进行控制的准确度。
本发明实施例提供一种转向灯的控制装置。图12为本发明实施例提供的转向灯的控制装置的结构图，如图12所示，转向灯的控制装置120包括：存储器121和处理器122；存储器121用于存储程序代码；处理器122，调用所述程序代码，当程序代码被执行时，用于执行以下操作：在车辆的转向灯开启后，检测所述车辆方向盘的状态；如果所述方向盘处于回正状态，且持续第一预设时间，则判断所述转向灯是否处于开启状态；若所述转向灯处于开启状态，则关闭所述转向灯。
