具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
弯道会车出事的概率很高，威胁人们的生命安全，例如，可以参见图1的示例，在图1中所示的弯道11所在的区域，由于有大山12的阻挡，通常行驶在道路13上的汽车14，与行驶在道路15上的汽车16之间将不能看到对方，在这种类型的弯道上比较容易发生会车相撞。如图1所示，在两车行驶至弯道11会车时，可能发生撞车事故。
本公开旨在提供一种弯道会车预警方法，以在弯道会车时自动进行预警，有效减少会车事故的发生。图2示例了该方法的流程，可以包括：
在步骤201中，接收汽车行驶位置信息。
例如，该方法是由弯道会车预警装置执行。在本步骤中，弯道会车预警装置可以接收到汽车行驶位置信息，该汽车行驶位置信息可以包括：汽车在不同时间点的GPS位置坐标，比如，在时刻t1，行驶的汽车位于坐标z1(可以是经纬度坐标)的位置；在时刻t2，行驶的汽车位于坐标z2的位置。
汽车行驶位置信息，可以是由汽车自身采集并发送至弯道会车预警装置。例如，行驶的汽车中可以装载有汽车导航设备，导航设备可以根据接收的GPS卫星信号对汽车进行定位得到所在汽车的位置坐标，发送至弯道会车预警装置。当弯道会车预警装置设置在导航设备中时，该弯道会车预警装置可以采集自身所在汽车的汽车行驶位置信息。
此外，汽车行驶位置信息中也可以包括汽车位置坐标之外的其他信息，比如，汽车在上述的坐标位置处的行驶速度。
在步骤202中，根据汽车行驶位置信息和道路信息，确定将要弯道会车的目标汽车。
例如，弯道会车预警装置可以根据接收到的汽车行驶位置信息以及道路信息，确定哪些汽车可能进行弯道会车，该道路信息例如可以包括：是否是单行道、是否是弯道，并且可以将这些会车的汽车称为“目标汽车”。例如，在图1中所示的汽车14和汽车16就可以为目标汽车。
在本步骤中，确定弯道会车的目标汽车的方式可以有多种，示例性的一种方式可以为，弯道会车预警装置根据汽车行驶位置信息可以确定汽车的行驶方向，比如，在时刻t1，行驶的汽车位于坐标z1，在时刻t2，行驶的汽车位于坐标z2，那么根据z1和z2就可以确定该汽车的行驶方向，比如可以判断出该汽车正在向弯道行进；同理可以找到向弯道行进的多个汽车。还可以进一步根据每个汽车的行驶速度(例如，可以根据时间和坐标计算速度)，估算出大致在哪个位置会有哪些汽车进行会车，即得到会车地点。
在步骤203中，对目标汽车进行弯道会车预警。
例如，在确定要进行弯道会车的目标汽车后，可以在本步骤对汽车进行预警。当上述的步骤201和步骤202可以由每个汽车自身单独执行时，弯道会车预警装置可以是装在汽车的导航系统内，那么每个汽车都可以计算自己是否要进行弯道会车，并在将要会车时对司机进行告警，比如在汽车内播放警示语音“前方将会车，请多加注意”；或者，该汽车还可以向在步骤202中得到的对方汽车发送警示提醒，当然也可以不发送，对方汽车也可以按照同样的方式得知会车并提醒自己的司机注意。
弯道会车预警装置还可以是装在服务器中，这样每个汽车都向服务器上报汽车行驶位置信息。当服务器在步骤202中得到要会车的目标汽车后，向目标汽车分别发送通知进行预警。
本实施例的弯道会车预警方法，可以根据汽车行驶位置信息和道路信息自动确定要进行会车的汽车，并自动对汽车进行弯道会车预警，这样可以及时有效的提醒司机注意，减少弯道会车事故的发生。
如下列举在两种可行的应用场景下执行的弯道会车预警方法：
图3示例了一种应用场景，如图3所示，在该场景中，弯道会车预警装置设置在服务器31，各个汽车都向服务器31上报一些参数，由服务器根据该参数进行弯道会车的判别和预警。图4示出了服务器执行的流程，包括：
在步骤401中，服务器可以接收多个汽车上报的在行进中处于不同时间点的位置坐标。
例如，在图3的示例中，汽车14、汽车16和汽车32都可以向服务器上报位置坐标，比如，以汽车14为例，汽车14在行驶过程中，可以通过车上的导航系统(例如，可以是车载导航或者手机导航)获取汽车的GPS坐标，并通过广域网将坐标不断上报至服务器，还可以上报汽车车速等其他信息。
在步骤402中，服务器可以根据汽车行驶位置信息和道路信息，判断哪些汽车要进行 弯道会车，确定会车的汽车为目标汽车。
例如，假设汽车32和汽车16将要在弯道11处进行弯道会车，对此服务器可以如下判断：服务器根据汽车32和汽车16在不同时间点上报的位置坐标，可以确定这两个汽车的行进方向，如图3中所示的箭头33为汽车32的行进方向，箭头34为汽车16的行进方向。接着，根据两个汽车所在的位置，以及汽车所在的道路(如，道路13、道路15和弯道11)，可以获知两个汽车相距的距离，再结合汽车的车速(可以是汽车上报或者由服务器根据时间和坐标计算得到)，就可以估算出两个汽车的会车地点，如图3所示。在该例子中，汽车32和汽车16则称为将在弯道会车的“目标汽车”。
此外，道路信息是预先存储在服务器31，该道路信息可以是汽车行驶所在的地图信息，包括：行驶所在的道路的长度、宽度，该道路与哪些道路交叉，哪里是弯道，或者，该道路的周边地形，比如，弯道处是否有大树、大山等容易遮挡行车视线的障碍物，弯道处是否有陡坡等。在该道路信息中，并不是所有的弯道都需要进行弯道预警，比如，即使是弯道，但是视野很开阔，并不影响会车双方司机的视线，那就可以不用预警。
可选的，本实施例可以只在具有会车事故危险的弯道处进行预警，那么服务器可以预先存储这些弯道的信息，比如，可以在道路信息预先标记哪些弯道是危险的需要预警的弯道，当服务器接收到汽车上报的汽车行驶位置信息后，可以先判断该汽车接近的弯道是否是危险弯道，如果不是危险弯道可以不做处理，如果是危险弯道则执行本步骤的处理，判定是否在该弯道会车。或者，服务器也可以不预存弯道信息，而是在处理的过程中根据道路信息判定汽车正在接近的弯道是否是危险弯道；比如，如果服务器发现该弯道处有大山，且根据汽车的行进方向确定该大山挡住了司机视线，则确定为危险弯道，继续判断汽车在哪些会车，是否在弯道处会车。
在步骤403中，服务器可以分别向将要弯道会车的各个目标汽车发送会车预警通知，以使得目标汽车在接收到通知时对司机进行弯道会车告警。
例如，服务器在估算到汽车32和汽车16的会车地点后，确定两者要进行弯道会车，则可以分别向这两个汽车发送会车预警通知，该通知例如可以是服务器发送至汽车内的导航系统。该通知的目的是指示目标汽车对其司机进行预警，比如，导航系统在接收到通知后，可以在汽车内进行语音提示“即将弯道会车，请您注意”，以提醒司机注意驾驶，尽量避免事故。
在本实施例的弯道会车预警方法中，是由服务器来进行弯道会车的判定和预警，这种方式中汽车只要上报位置信息即可，对于汽车来说实施简单；并且，服务器判定会车可以准确的确定会车的目标汽车，只向目标汽车发送预警通知，不必警示所有的汽车，更具有预警的针对性和有效性。
图5示例了另一种应用场景，在该场景中，弯道会车预警装置可以设置在导航设备，该导航设备可以是汽车内的车载导航或移动终端导航，也就是说，本公开的弯道会车预警方法由各个汽车分别执行。
如图5所示，以在道路13上行驶的汽车14和在道路15上行驶的汽车16为例，假设这两个汽车将弯道会车。弯道会车预警方法可以按照图6所示的流程执行，图6所示的流程适用于每个汽车，如汽车14或者汽车16：
在步骤601中，导航设备所在的汽车获取汽车的位置坐标，称为第二位置坐标，并根据位置坐标和道路信息，确定汽车在向弯道行进。
例如，汽车14内的车载导航系统可以通过接收GPS信号确定汽车14的经纬度坐标，可以称为第二位置坐标，并且可以不断的获取，得到在行驶过程中不同时间点的坐标，从而判定汽车的行进方向。结合汽车14行驶的道路信息，可以确定汽车14按照上述行进方向继续行进就将接近弯道11。同理，汽车16的导航设备也可以按照同样方式确定汽车16的行进方向。在图5中，以箭头33表示汽车14的行进方向，以箭头34表示汽车16的行进方向。
在步骤602中，在汽车与弯道的距离在预设距离阈值内时，广播发送汽车在行进中处于不同时间点的位置坐标。
例如，汽车的导航系统在行驶过程中可以不断的对汽车的行驶位置进行定位，但是，并不需要一直进行广播，本步骤中，可以在汽车与弯道的距离在预设距离阈值内时，广播发送汽车在行进中处于不同时间点的位置坐标。示例性的，参见图5所示，假设汽车14按照箭头33的方向继续行进即将接近弯道11，并且当前位置与弯道11之间的距离S已经在阈值范围内，即足够近，则汽车14的导航系统可以开始进行广播，将汽车14的第二位置坐标广播出去。例如可以通过wifi数据广播或者蓝牙方式发送。
在步骤603中，汽车接收到的其他汽车广播的在行进中处于不同时间点的位置坐标，称为第一位置坐标。
例如，汽车14在步骤602中广播的第一位置坐标可以被汽车16中的导航系统接收到；同理的，汽车16也可以执行步骤601和602，并且广播的汽车16的第一位置坐标会被汽车14接收到。也就是说，每个汽车都会接收到其他汽车发送的第一位置坐标，也可以获取到自己的第二位置坐标。
在步骤604中，汽车根据第一位置坐标、汽车的第二位置坐标和道路信息，确定导航设备所在汽车与其他汽车将要弯道会车。
例如，汽车可以根据上述的第一位置坐标、汽车的第二位置坐标和道路信息，判断该汽车自身是否会进行弯道会车。仍以汽车14为例，汽车14可以根据自己的第二位置坐标，确定自己的行进方向，并且根据接收到的汽车16的第一位置坐标确定汽车16的行进方向；并且，汽车14还可以根据不同时间点的位置坐标确定自己和汽车16的行进速度。
结合道路信息，汽车14就可以估算出自己与汽车16将在弯道11处进行会车，并且，弯道11处由于有比较多的树木和山体，行车视野不佳，属于危险弯道，据此，可以继续执行步骤605。
在步骤605中，在导航设备所在汽车内对司机进行弯道会车告警。
例如，汽车14内的车载导航可以对司机进行语音提示。此外，汽车14可以向汽车16发送预警通知，或者，也可以不向汽车16发送通知，因为汽车16自身也会进行图6所示的各步骤处理，得知自己将与汽车14进行弯道会车，并在自身汽车内对司机进行预警。
在本实施例的弯道会车预警方法中，是由各个汽车各自来进行弯道会车的判定和预警，不需要服务器参与，当汽车没有广域网功能时就可以按照该方式进行预警，适用性更广。
此外，如果汽车既没有广域网功能，也没有GPS导航，那么可以由司机手动在接近弯道时触发广播功能，比如，司机在接近弯道时，根据观察的周边地形判断这是个危险弯道，可能出现会车事故，那么司机可以通过手动触发按键的方式，触发汽车向外广播位置信息。
图7是根据一示例性实施例示出的一种弯道会车预警装置的结构，该装置可以执行上述的弯道会车预警方法。如图7所示，该装置可以包括：信息接收模块71、会车确定模块72和会车预警模块73。
