作为一种可选实施例，距离探测器包括红外线距离探测器和声纳探测器。
上述所有可选技术方案，可以采用任意结合形成本发明的可选实施例，在此不再一一赘述。
图2是根据一示例性实施例示出的一种路况提示方法的流程图，该路况提示方法应用于终端。如图2所示，该运行数据的调节方法包括以下步骤。
在步骤201中，当接收到对移动终端上预设功能的触发指令时，对预设范围内的路面情况进行检测。
其中，预设功能可以为移动终端上的系统自带功能，也可以为移动终端上安装的应用所提供的功能，本实施例对此不作具体限定。例如，预设功能可以为移动终端上的手电筒功能。当检测到启动移动终端的手电筒时，可对移动终端的预设范围内的路面情况进行检测。或者，预设功能还可以为移动终端上安装的路况检测应用所提供的路况检测功能。当检测到启动上述路况检测功能时，可对移动终端的预设范围内的路面情况进行检测。相应地，预设功能的触发指令可以为移动终端上的手电筒应用的触发指令，也可以为路况检测应用的触发指令等，本实施例对此不作具体限定。
另外，预设范围可以为移动终端正前方预设半径的扇形区域，本实施例不对预设范围的形成方式作具体限定。决定扇形区域面积大小的预设半径可以根据需求进行设定，本实施例不对预设范围的大小作具体限定。例如，预设范围可如图3所示。
当接收到对移动终端上的手电筒应用的触发指令时，关于对预设范围内的路面情况进行检测的方式，本实施例对此不作具体限定，包括但不限于：开启移动终端上配置的距离探测器，对预设范围内的路面情况进行检测。其中，距 离探测器可以包括红外线距离探测器和声纳探测器，本实施例不对距离探测器的类型作具体限定。距离检测器可检测到预设范围内路面上的路障，并可以测量出路面上的路障与移动终端之间的距离。路障可以包括路面上的障碍物、凸起物，还可以包括路面上的坑洞、积水等。
需要说明的是，当移动终端上同时安装有红外线距离检测器及声纳检测器时，红外线距离检测器与声纳检测器还可以互相结合，以对路况进行检测，本实施例对此不作具体限定。另外，红外线距离检测器及声纳检测器可以安装在移动终端的后置摄像头上，还可以安装在移动终端的其它位置，本实施例对此不作具体限定。
在步骤202中，确定移动终端与距离最近的障碍物之间的距离。
当通过声纳检测器检测路面情况时，声纳检测器可向移动终端正前方发射声波，声波遇到障碍物会返回，即声纳检测器能接收到回声。由于声波在空气中的传播速度已知，声纳检测器发出声波到接收到回声之间的间隔时间也可以确定，因此，可计算移动终端与正前方每个障碍物之间的距离。从所有的计算结果中选择距离的最小值，即为移动终端与距离最近的障碍物之间的距离。当通过红外线距离检测器检测路面情况时，测量移动终端与障碍物之间距离的方式可参考上述内容，此处不再赘述。
在步骤203中，当距离在预设范围内时，确定预设范围内的路面上存在路障。
以预设范围为移动终端正前方预设半径的扇形区域为例，当距离小于预设半径，且距离最近的障碍物与移动终端所在位置所形成的夹角小于预设角度时，可确定距离最近的障碍物在预设范围内，即可确定预设范围内的路面上存在路障。当距离大于预设半径，或距离最近的障碍物与移动终端所在位置所形成的夹角不小于预设角度时，则确定预设范围内不存在路障。
例如，在图4中，障碍物A与移动终端之间距离小于扇形区域的半径，即 距离小于预设半径。障碍物A与移动终端之间的连线和竖直线之间的夹角a小于扇形区域的左边界线和竖直线之间的夹角m，即形成的夹角小于预设角度。因此，如图4所示，障碍物A在预设范围内，即可确定预设范围内的路面上存在障碍。
在图5中，障碍物B虽然与移动终端之间的距离小于扇形区域的半径，但由于障碍物B与移动终端之间的连线和竖直线之间的夹角大于m，即形成的夹角大于预设角度，因此，如图5所示，障碍物B不在预设范围内。障碍物C与移动终端所在位置所形成的夹角虽然小于预设角度m，但由于障碍物C与移动终端之间的距离大于扇形区域的半径，因此，障碍物C也不在预设范围内。
需要说明的是，上述步骤202至203主要为判断预设范围内的路面上是否存在路障的过程。当然，除了上述202至203中的判断方式之外，在判断预设范围内的路面上是否存在路障时，还可以确定预设范围内的路面上的障碍物的面积，当存在面积大于第一预设阈值的障碍物时，确定预设范围内的路面上存在路障。其中，上述方法主要应用于障碍物为坑洞的情形，第一预设阈值可根据需求进行设定，如可以为0.1平方米，本实施例对此不作具体限定。另外，上述判断预设范围内的路面上是否存在路障的方式还可以互相结合，以提高路障检测的准确率，本实施例对此不作具体限定。
在步骤204中，当预设范围内的路面上存在路障时，输出提示信息。
关于输出提示信息的方式，本实施例对此不作具体限定，包括但不限于如下几种输出方式：
第一种输出方式：获取预先存储的第一语音提示文件，播放第一语音提示文件；其中，第一语音提示文件用于提示用户注意前方路面情况。
例如，第一语音提示文件中的语音内容可以为“请您注意当前路况”。当预设范围内的路面上存在路障时，可以重复播放上述语音内容，以提示用户注意路况。
第二种输出方式：根据预设范围内的路面情况生成第二语音提示文件，播放第二语音提示文件。
根据预设范围内的路面情况可确定移动终端与障碍物之间的距离，根据移动终端与障碍物之间的距离可生成第二语音提示文件。
例如，若根据预设范围内的路面情况，确定移动终端与障碍物之间的距离为5米。根据移动终端与障碍物之间的距离，可生成第二语音提示文件。第二语音提示文件的语音内容可以为“您前方5米处存在障碍物，请注意”。播放上述语音内容，能够提示用户注意前方的障碍物。
第三种输出方式：根据预设范围内的路面情况和移动终端的移动速度，生成第三语音提示文件，播放第三语音提示文件。
其中，在根据预设范围内的路面情况生成第三语音提示文件时，可获取移动终端的移动速度，根据移动终端与距离最近的路障之间的距离及移动速度，计算用户到达路障所需的时间，当时间小于第二预设阈值时，根据时间及移动速度，生成第三语音提示文件，第三语音提示文件用于提示用户减速并改变移动方向。
例如，以第二预设阈值为5秒为例。当用户手持移动终端的移动速度为2米每秒，且移动终端与距离最近的路障之间的距离为8米时，则可确定用户到达路障所需的时间为4秒。由于计算得到的时间4秒小于第二预设阈值5秒，因此，根据时间及移动速度，生成第三语音提示文件。第三语音提示文件的语音内容可以为“您当前移动速度为2米每秒，4秒后可能会碰到路障，请您降低您的移动速度，并变更移动方向”。播放上述语音内容，即可提醒用户减速并改变移动方向以避开路障。
第四种输出方式：按照预设频率控制指示灯的开关状态，使得指示灯按照预设频率进行闪烁。
例如，以指示灯为移动终端上摄像头的闪光灯为例。将预设频率设置为每 秒1次，即每间隔一秒改变闪光灯的开关状态，从而闪光灯每秒钟会闪一次，从而可提示用户注意前方路面情况。
当然，除了上述输出提示信息的方式之外，还可以通过振动、响铃的方式提示用户注意路面情况，本实施例对此不作具体限定。
需要说明的是，还可以将上述几种输出方式相结合以提示用户注意路况，本实施例对此不作具体限定。例如，移动终端在进行语音提示时，还可以同时振动或使得指示灯按照预设频率进行闪烁等，以增加用户察觉到的可能性。
本公开实施例提供的方法，通过在接收到对移动终端上预设功能的触发指令时，对预设范围内的路面情况进行检测，当预设范围内的路面上存在路障时，输出提示信息。由于可以自动对移动终端的预设范围内的路面情况进行检测，从而为用户提供了一种更简捷的路况检测方式。另外，由于可根据检测结果输出提示信息以提示用户注意路面情况，因此，能够保障用户安全，避免用户因路障而受伤。

在一个实施例中，该输出模块602被配置为获取移动终端的移动速度；根据移动终端与距离最近的路障之间的距离及移动速度，计算用户到达路障所需的时间；当时间小于第二预设阈值时，根据时间及移动速度，生成第三语音提示文件。
