具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
图1示出了根据本公开第一个实施例的车辆控制方法的流程图，下面将参照图1来介绍本公开第一个实施例的车辆控制方法100。本公开实施例中 的车辆控制方法可以应用于各种机动车辆，该机动车辆至少包括驱动系统(例如发动机或电动机、离合器等)、处理器、控制器等部件，以对车辆的操作进行控制。
此外，在本发明实施例中，当车辆开启了发动机自动启停功能后，可以在刹车静止状态下，自动停止发动机工作，在刹车释放时启动发动机进行工作，从而可进一步启动车辆开始行使。当车辆关闭了发动机的自动启停功能后，则关闭上述功能。
参见图1，在车辆控制方法100的步骤S101中，判断所述车辆是否处于短时间等待状态。在本发明实施例中，短时间等待状态就是车辆处于静止等待状态的时间相对较短。
在步骤S102中，当判断结果为车辆处于短时间等待状态，则关闭所述车辆的自动启动功能。
根据本公开的一个示例，可以至少根据车辆的当前刹车频率判断所述车辆是否处于短时间等待状态。当刹车频率高时，确定所述车辆处于短时间等待状态，否则，当刹车频率低时，确定所述车辆不处于短时间等待状态。
例如，可以通过刹车频率阈值来判断刹车频率的高低。当所述车辆的当前刹车频率大于刹车频率阈值时，确定所述车辆处于短时间等待状态，否则，确定所述车辆不处于短时间等待状态。例如，车辆处于拥堵状态时，往往会不断地进行启动和刹车操作，此时则可以判断所述车辆的刹车频率参数。例如，通过计算固定时间内刹车次数，来计算刹车频率参数。例如，可以获取当前之间之前1、3、5或10分钟内的刹车次数，当确定刹车频率参数大于等于预定的频率阈值时，例如刹车频率大于等于4次时，则表示车辆走走停停，还可以走得动，不是十分拥堵，因此可以判断此时处于短时间等待状态。此时可以关闭所述车辆的自动启停功能。从而避免了发动机短时间内连续启停对发动机寿命的影响。
此外，如果确定刹车频率参数小于预定的频率阈值时，则可能表示非常拥堵，车辆很难移动。例如，当刹车频率小于4次时，通常可以确定当前路况处于非常拥堵的状态，此时可以判断车辆不处于短时间等待状态。在此情况下，可以启动车辆的自动启停功能，在车辆处于刹车静止状态时，关闭发动机，以节省能耗，减少尾气排放等。在刹车释放时启动发动机进行工作。
根据本公开的另一个示例，还可以根据所述车辆的当前刹车频率和当前 位置判断所述车辆是否处于短时间等待状态。当判断出车辆的当前刹车频率大于刹车频率阈值时，可以进一步获取车辆的当前位置信息，根据当前位置信息来判断车辆是否处于特殊路况环境中而不是单纯地处于堵车状态。例如，可以获取车辆当前的地理坐标、行驶方向、行驶道路和/或正在通过或将要通过的前方路口等位置信息。例如，车辆中可以安装有定位装置(例如，GPS定位装置、北斗定位装置、手机基站定位装置等，或这些装置的任意组合)，以实时(例如延迟小于5秒，优选小于3秒)获取车辆的地理位置信息。
例如，可以根据获取的位置信息判断车辆是否在等待红绿灯。当所述车辆的当前刹车频率大于刹车频率阈值且所述车辆不在等待红绿灯时，确定所述车辆处于短时间等待状态，否则，确定所述车辆不处于短时间等待状态。
根据本发明的一个示例，首先，基于当前位置获取与所述当前位置对应的实时交通信息，然后，进一步基于实时交通信息判断所述车辆是否在等待红绿灯。如果车辆没有等待红绿灯，结合车辆的当前刹车频率大于刹车频率阈值的信息，则可以判断当前车辆在非等红绿灯状态下处于走走停停状态，则可以判断车辆处于短时间等待状态，此时可以关闭自动启停系统。如果根据获取的位置信息对应的实时交通信息，确定所述车辆在等待红绿灯，那么车辆很可能是在等红灯状态下不停刹车，从而导致刹车频率大于预设的刹车频率阈值，此时可以判断出车辆不一定是处于拥堵状态中，因此，确定车辆不处于短时间等待状态。那么此时可以开启自动启停系统。
根据本发明的一个实施例，还可以根据所述车辆的当前位置判断所述车辆是否处于短时间等待状态。可选地，如前所述，可以获取车辆当前的地理坐标、行驶方向、行驶道路和/或正在通过或将要通过的前方路口等位置信息。例如，车辆中可以安装有定位装置(例如，GPS定位装置、北斗定位装置、手机基站定位装置等，或这些装置的任意组合)，以实时(例如延迟小于5秒，优选小于3秒)获取车辆的地理位置信息。
可选地，车辆的车载系统还可以通过有线或无线网络与一交通信息系统连接，以获得车辆当前位置的交通信息。例如，可以将车辆当前的位置信息通过网络发送给上述交通信息系统。该交通信息系统中包含某个城市或某个区域的实时交通信息。例如，该区域每个路口的路况信息、交通管制信息、该区域所有路口的交通信号灯信息等等。该交通信号灯信息例如包括：信号 灯所在路口、信号灯所在位置、编号、信号灯的当前颜色，该颜色剩余时间等等。车辆将获取的当前位置通过网络发送给上述交通信息系统，并请求返回对应当前位置的实时交通信息。可替换地，车辆也可以与交通信息系统的交通信息一直保持同步状态。交通信息系统可以通过网络将所有的实时交通信息全部传送给车辆，并定时更新，使得车辆中的实时交通信息与交通信息系统中的信息保持同步。这样，车辆就可以基于当前位置信息获取到对应该位置的实时交通信息，并根据该实时交通信息来判断，车辆是否在等待交通信号灯，需要等待的时间等信息。
根据本发明的一个示例，基于所述当前位置获取与所述当前位置对应的实时交通信息。实时交通信息可以是车辆是否在等待红绿灯(例如，红灯或黄灯)。当所述实时交通信息反映当前位置为等待红绿灯位置时，还可以进一步确定从当前时刻起所述车辆所要等待红绿灯的等待时间，根据等待时间进一步确定是启动还是停止自动启停功能。若所述等待时间小于阈值时间时，确定所述车辆处于短时间等待状态，否则，确定所述车辆不处于短时间等待状态。
例如，车辆获取实时交通信息时，除了获取前方路口的信号灯颜色，还获取到该颜色信号灯的剩余时间。例如车辆等待红绿灯的剩余时间小于15秒时，可以确定为车辆处于短时间等待状态，可能表示车辆马上要继续行驶，此时关闭自动启停功能，无需停止发动机的工作，如此智能控制自动启停系统，不但可以节能环保，还可以延长发动机的寿命。相反，当所述等待时间大于等于预定的时间阈值时，则确定车辆不处于短时间的等待状态，则可以开启所述车辆的自动启停功能。例如，当等待红灯的时间大于等于15秒时，此时开启车辆的自动启停功能。这样，在等待红灯的剩余时间大于等于15秒的情况下，自动启停系统将在车辆处于刹车状态且速度为零时，自动停止发动机工作；在车辆处于刹车释放状态时，重新启动发动机的工作。如此可以有效地节省能源，减少污染，并且延缓发动机的损耗、老化等。
此外，根据本发明的一个示例，在关闭所述车辆的自动启动功能之前，还可以确定所述车辆的所述自动启停功能为通过自动方式开启或关闭而非手动方式开启或关闭。
例如，用户在不需要自动启停功能时，往往会手动关闭该功能。在用户习惯用自动启停系统时，也会手动开启该功能。因此，为了适应用户的习惯， 根据本公开的一个示例，关闭所述车辆的自动启停功能的步骤之前，还可以进一步判断车辆的自动启停功能是否处于以自动方式开启或关闭而不是手动方式开启或关闭。当判断是以自动方式开启或关闭时，则可以执行前述实施例的关闭自动启停功能的步骤。当判断是以手动方式开启或关闭时，则以手动方式优先原则，不再执行前述实施例的关闭或开启自动启停功能的步骤。
例如，在前述确定当刹车频率参数大于等于预定的频率阈值之后，进一步判断车辆的自动启停功能是否处于手动关闭状态或手动开启状态。当判断车辆的自动启停功能处于手动关闭状态，则不再启动自动启停功能。而当判断车辆的自动启停功能处于手动开启状态时，则以用户手动设置优先，仍然保持在启动所述车辆的自动启停功能状态。
当然，本领域技术人员应当了解，手动关闭开启状态的确定步骤也可以在判断车辆是否在等待红绿灯之前，也可以在获取车辆当前位置之前，当确定用户已手动关闭自动启停功能后，就无需再进行位置获取或等待判断了，从而可以节省处理器资源。
本公开实施例，通过判断车辆是否处于短时间等待状态，从而在车辆处于短时间等待状态时，例如在等待信号灯或拥堵程度不高的情况下，关闭自动启停系统，可以避免发动机在短时间内反复自动熄火和点火降低发动机的寿命，还有利于节油，环保。而在车辆不是处于短时间等待状态时，开启自动启停系统，自动启停系统可以使得车辆处于刹车状态且速度为零时，自动停止发动机工作，以节省能源、降低排放并减少发动机的损耗、老化等。

定位装置340例如可以是全球定位系统(GPS)装置、北斗定位装置、手机基站定位装置或多种定位装置的任意组合等，即可以获取车辆当前位置的装置来实现。定位装置340可以获取车辆当前的地理坐标信息，并且还可以根据地理坐标信息和/或车辆的移动位移，获取到车辆行驶方向、行驶道路、正在通过或将要通过的路口等位置信息。例如，车载系统300可以包括通信单元350，通信单元350被配置为基于当前位置获取与当前位置对应的实时交通信息。通信单元350例如包括接收器、发送器、网络通信接口以及天线等部件。车载系统300可以通过通信单元350将定位装置340获取的车辆的当前地理坐标信息发送给与车载系统通过网络连接的交通信息系统，交通信息系统根据车辆当前的地理坐标信息返回该车辆当前所在位置的交通信息。例如：路况信息、交通管制信息，该位置以及该位置附近区域所有路口的交通信号灯信息等等。该交通信号灯信息例如包括：信号灯所在路口、方向、编号、信号灯的颜色、该颜色的信号等剩余时间等等。上述交通信息通过车辆的通信单元350接收，并反馈给车辆的车载系统的处理器320。
处理器320，被配置为根据当前位置判断车辆是否处于短时间等待状态。例如，处理器320判断车辆是否处于拥堵状态，或者基于实时交通信息判断车辆是否处于等待交通信号灯状态。基于判断结果确定启动或停止车辆的自动启停功能，并将启动自动启停功能的启动信号或停止自动启停功能的停止信号发送给控制器310。
控制器310被配置为接收处理器320发送的关于自动启停功能的启动信号或停止信号，并根据启动信号控制车辆的启动的发动机的开启。例如，当 控制器310接收到处理器320发送的自动启停功能开启信号时，开启车辆的自动启停功能，当控制器310接收到处理器320发送的关闭自动启停功能的关闭信号时，关闭车辆的自动启停功能。并且，当自动启停功能开启，并且当获得车辆处于刹车静止状态的信号时，控制器310进一步控制关闭发动机。当自动启停功能开启并获得车辆刹车释放的信号时，控制器310进一步启动发动机。而当自动启停功能关闭后，即使获得了车辆处于刹车静止状态的信号，处理器320也不会向控制器310发送启动或关闭自动启停功能的信号，因此控制器310不会关闭或启动发动机如此可以智能控制发动机的开启或关闭，保证发动机的寿命。
本公开实施例的车载系统，能根据接收到的车辆状态有选择地开启或关闭自动启停功能，从而最大限度节省燃油，降低排放。
以上是根据本公开第三个实施例的车载系统，下面将进一步介绍根据本公开点第四个实施例的车辆控制系统。图4示出了根据本公开第四个实施例的车辆控制系统400，如图4所示，车辆控制系统400包括车载系统410，还包括交通信息系统420。车载系统410为本公开第三个实施例所描述的车载系统，具体结构和功能参见本公开第三个实施例，在此不再赘述。
在车辆控制系统400中，交通信息系统420将交通信息发送给车载系统410，该交通信息系统420中包含某个城市或某个区域的实时交通信息。例如，该区域每个路口的路况信息、交通管制信息、该区域所有路口的交通信号灯信息等等。该交通信号灯信息例如包括：信号灯所在路口、方向、编号、信号灯的颜色、该颜色的信号等的剩余时间等等。
车载系统410根据所述交通信息确定启动或停止所述车辆的自动启停功能。车载系统410与交通信息系统420可以通过有线通信网络或无线通信网络(例如，通过互联网，蜂窝网络等)进行连接。交通信息系统420将所述交通信息通过网络发送给所述车载系统410。
本公开实施例的车辆控制系统，能根据实时交通信息对车辆进行控制，确定是否开启车辆的自动启停功能，从而使得车辆的自动启停功能更加实时性，智能化。
以上所述仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范 围应以所述权利要求的保护范围为准。
本申请要求于2016年3月11日递交的中国专利申请第201610139680.4号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
