本发明实施例涉及智能硬件领域，尤其涉及通过移动终端与汽车结合的智能场景。
背景技术
当今社会汽车的拥有量越来越大，而随着人们生活水平的提高，对汽车也提出了智能化的要求。但是，由于汽车是大件耐用品，并不会经常更换。除了少部分新车外，现存数量庞大的汽车要进行智能化，都要花费高昂的费用进行改造，而改造还有可能失去厂家的质保。而在另一方面，随着现代科技的发展，使得人们对智能化提出了更高要求。特别是汽车作为交通工具，经常在不同场景之中移动。智能提醒功能对于汽车的使用者来说更是日益重要。
因此，现存的大量汽车需要一种方便易行，成本低廉的智能化改造方案来实现智能提醒。
发明内容
有鉴于此，本发明实施例提供了一种用于汽车的智能提醒方法及装置，使得现存大量的汽车能够实现智能化而无须成本高昂的改造，以提高汽车的安全性和使用的便利性。

具体实施方式
图1为根据本发明一种可能的实施方式提供的提醒系统的示意图。如图1所示，汽车包括车身21和车顶灯22。车顶灯22设置于车身21的乘客座舱顶部，用于提供照明。当汽车的车门被打开时，车顶灯22会亮起。
在一种可能的实施方式中，车顶灯22也可以设置在车身21上的其它位置，或者不是用于照明，只要当汽车的车门被打开时会亮起即可。
提醒设备设置在汽车上。提醒设备可以包括移动终端11和传感器12。传感器12设置在车顶灯22附近，用于检测车顶灯22是否亮起。
在一种可能的实施方式中，只要在车门打开时会自动亮起的灯，都可以使用传感器12来检测车门是否被打开。这些灯包括但不限于仪表盘的指示灯，工具箱灯，车门灯等。为描述方便，下文都用车顶灯来描述，并不代表本发明局限于这一技术方案。
进一步的，在一种可能的实施方式中，汽车的车门上设置有朝向后方的门灯。在汽车的车门被打开时，门灯会亮起，从而警示后方的行人或车辆。传感器12可以设置在门灯附近，以检测门灯是否亮起。例如，在车门上设置的朝向后方的门灯可以参考http://www.instructables.com/id/Preventive-lights-for-door-edge/的技术方案来实现。
更进一步的，在一种可能的实施方式中，传感器12可以设置在所有可能在车门打开时亮起的车灯附近。例如，不同的车门打开时，可能会有不同的车灯对应亮起，通过本实施方式的设置，可以保证无论打开哪个车门，都能实现有效的提醒。
在一种可能的实施方式中，传感器12可以是光线传感器，红外温度传感器或电磁传感器等现有的电子元件，以实现检测车顶灯22是否亮起。
在一种可能的实施方式中，传感器12与移动终端11通过无线方式进行连接。无线方式可以包括声波、红外、蓝牙、WIFI等，还可以使用任一通信标准或协议，包括但不限于GSM(Global System of Mobile communication，全球移动通讯系统)、GPRS(General Packet Radio Service，通用分组无线服务)、CDMA(Code Division Multiple Access，码分多址)、WCDMA(Wideband Code Division Multiple Access,宽带码分多址)、LTE(Long Term Evolution,长期演进)、电子邮件、SMS(Short Messaging Service，短消息服务)等。
图2为根据本发明一种可能的实施方式提供的提醒方法的流程图。如图2所 示：
步骤200，开始。
步骤201，移动终端11检测汽车是否熄火或停止。本申请中使用的汽车熄火的表述等同于汽车发动机熄火。
在一种可能的实施方式中，移动终端11具有运动传感器，如加速度传感器或陀螺仪，用来检测汽车是否熄火或停止。本发明实施例利用现有的移动终端11来执行对汽车运动状态的检测，解决了现有的大量汽车并没有配备智能化系统的问题，又避免了对汽车进行复杂改造的过程，降低了成本。
步骤202，当移动终端11检测到汽车熄火或停止后，指示传感器12检测车顶灯22是否打开。
在一种可能的实施方式中，传感器12在被移动终端11唤醒之前，保持低功耗的待机状态，以节省能源和延长待机时间。在被移动终端11唤醒之后，传感器12对车顶灯22的状态进行检测，并将结果回馈给移动终端11。
值得一提的是，在可替代的实施方式中，传感器12可以一直保持对车顶灯22状态的检测，以提高检测的准确性。
步骤203，当移动终端11收到传感器12发送的检测结果为车顶灯22亮起时，移动终端11向用户发出提醒。
步骤204，结束。
本发明实施例在检测到汽车熄火或停止后，再结合车顶灯22的状态来判断是否向用户发出提醒。这避免了在某些场合下的误判，以避免对用户造成困扰。例如用户在行车过程中，只是偶尔打开车顶灯22用于照明，此时无须启动提醒服务。
在一种可能的实施方式中，移动终端11向用户发出的提醒包括语音提醒和/或灯光提醒，以引起用户的注意。例如，移动终端11可以发出特定节奏的蜂鸣声，或者播放音乐，或者播报语音提示。移动终端11也可以点亮指示灯，或者闪烁闪光灯，或者点亮屏幕，或者在屏幕上播放预定内容，以吸引用户的注意 或直接将信息传达给用户。
在一种可能的实施方式中，提醒的内容包括开门时请留意后方有无行人或来车。道路上常见的一种交通事故就是因为汽车内的乘员在开门之前没有仔细观察，造成打开的车门与后方的行人或来车发生碰撞，或者行人或来车为了躲避打开的车门而与路上的其它行人或车辆发生碰撞。因此本发明实施例在汽车熄火或停止，车门刚要打开的时候发出提醒，能够提高安全性。
在一种可能的实施方式中，提醒的内容包括请用户带上应该携带的物品，不要遗忘在汽车内。随身物品被遗忘在车内不但会对用户的生活造成不便，还有可能引来窃贼的砸窗盗窃，造成物品的失窃和汽车的损坏。
在一种可能的实施方式中，提醒的内容可以具体指出应该携带的是哪些物品，例如提醒用户带上移动终端11本身。
进一步的，移动终端具有一个可维护的物品提醒列表，以视觉或语音的方式提醒用户，例如将要携带的物品列表显示在移动终端11的屏幕上，或者将列表上的物品通过语音依次报出，使得用户可以核对是否已携带齐全。
在一种可能的实施方式中，移动终端11还具有定位功能，并通过定位的结果来确定提醒内容。定位可以通过基站定位、GPS定位或者惯性导航定位等方式来实现。
在一种可能的实施方式中，移动终端11根据定位的结果提醒用户当前区域的天气情况。例如不久有可能会下雨，建议带上雨伞。或者有可能会有大风，建议寻找安全的地方泊车。或者阳光强烈，建议用户采取防晒措施等。
在另一种可能的实施方式中，移动终端11根据定位的结果提醒用户当前区域的治安情况。例如告知用户附近街区偷盗或抢劫的案件发生率，或者汽车的偷盗率等，提醒用户不宜久留。
在又一种可能的实施方式中，移动终端11根据定位的结果提醒用户附近的饭店或电影院等消费场所，或者博物馆或体育馆等文娱场所，供用户进行选择。
下面是本发明实施例应用中的一个具体例子：
首先利用移动终端11上的运动传感器(加速度传感器、陀螺仪)不断采集运动数据并建模，通过模型匹配，可以检测出汽车发动机引起的低频震动和汽车运动状态的变化，并由此判断出汽车的行驶状态；一旦根据数据的变化发现震动消失，即可根据模型判断出汽车已经停车熄火；此时安装于车顶灯旁边的光线传感器12启动检测，当驾驶人在打开车门的一瞬间，车辆的行车电脑会通过车门传感器检测到车门打开事件并即刻点亮车顶灯22(所有车辆顶灯都有door设置，车门上都有行程开关)，此时车顶灯22旁的光线传感器12就会检测到光线亮度的变化，并将报警信号发送回手机(移动终端12)，手机即刻快速发出报警提醒信号，可以是语音提示也可以是声响提示，从而提醒驾驶人开门时注意观察车后情况再开门，从而达到防止非机动车与车门发生碰撞的目的。
图3为根据本发明另一种可能的实施方式提供的提醒方法的流程图。如图3所示，本发明实施例包括以下步骤：
步骤一：利用移动终端11上的运动传感器采集数据：移动终端11上的运动传感器不间断采集汽车运动数据；
步骤二：对汽车运动数据进行分析与建模并判断行车状态：对运动传感器采集到的汽车运动数据进行分析，可以检测出汽车发动机引起的低频震动和汽车运动状态的变化，并由此判断出汽车当前的行驶状态；
步骤三：移动终端11检测到汽车熄火或停止后启动光线传感器12采集数据并做判断：当检测出汽车停止后，移动终端11控制车顶光线传感器12启动检测，该光线传感器12为小体积低成本低功耗器件，置于车顶灯22旁边的光线传感器12开始采集车顶灯22附近光照数据并做判断，一旦检测到光线数值的变化达到阈值，则可确信车门已被打开，即刻将报警信号发送回移动终端11；
步骤四：移动终端11根据车辆状态和光线变化触发预警服务：移动终端11快速发出报警提醒信号，可以是语音提示也可以是振动或光照提示，从而提醒驾驶人开门时注意观察车后情况再打开车门。
图4为根据本发明一种可能的实施方式提供的提醒方法判断汽车行驶状态 的流程图。如图4所示，本实施方式与图3所示的实施方式的相同之处不再赘述，移动终端11具有加速度传感器用来采集汽车运动数据，对运动数据进行分析与建模并判断行车状态。
对采集到的运动数据进行分析，通过检测判断，可以检测出汽车发动机引起的低频震动和汽车运动状态的变化，对加速度传感器x轴、y轴和z轴数值Acc_x、Acc_y、Acc_z直接采用能量检测的方法，判断汽车行驶状态如下：
(1)单位时间内Acc_z的能量是否大于阈值Wz来判断发动机工作状态，如果大于阈值，则判定汽车发动机处于工作状态，如果小于阈值，则判定汽车发动机处于停止状态，即熄火状态；
(2)单位时间内Acc_x或Acc_y的能量是否大于阈值Wx或Wy来判断汽车行驶状态，如果x轴和y轴加速度能量有一个或一个以上大于阈值则判定汽车处于行驶状态，反之，则判定汽车处于停止状态；
(3)单位时间内Acc_x、Acc_y和Acc_z的能量是否大于阈值Wx、Wy和Wz来判断汽车状态，如果x轴、y轴和z轴全部小于阈值，则判定汽车处于停止并且熄火状态，反之，则判定汽车处于运动状态或者发动机处于工作状态。
其中，z轴为竖直于水平面的方向轴，x轴和y轴为车辆行驶的方向轴。
汽车在熄火或者停止状态时，或者在停止并且熄火状态时，移动终端11可以指示传感器12检测车顶灯22状态。
图5为根据本发明另一种可能的实施方式提供的提醒方法判断汽车行驶状态的流程图。如图5所示，与图4中的实施方式不同的是，本实施方式移动终端11可以结合陀螺仪判断汽车运动状态，当三轴角度变化值中有一个大于阈值时，可以判断汽车处于运动状态。
图6为根据本发明一种可能的实施方式提供的传感器12的工作示意图。如图6所示，本实施方式中传感器12可以为光线传感器，移动终端11检测到汽车熄火或停止后启动光线传感器12采集数据并做判断。
当检测出汽车处于停止或者发动机处于停止状态时，移动终端11发送指令 控制设置在车顶的光线传感器12启动检测，安装于车顶灯22旁边的光线传感器12开始采集车顶灯附近光照数据并做判断。光线采集可以采用脉冲的方式，即每隔一段时间△T采集一次光强，一旦检测到光强数值的变化△I达到阈值时，则可确信车门已被打开，即刻将报警信号发送回移动终端。阈值的设定以如下公式作为案例参考，但不限于此方法：
Figure PCTCN2016081734-appb-000001
公式含义为，每次检测到的光强与前一次做差，并进行累加求平均，当检测到第i+1次的光强变化大于前i次光强变化的平均值的N倍时，则光强数值变化达到阈值。
图7为根据本发明一种可能的实施方式提供的移动终端11的结构图。如图7所示，移动终端11包括处理器和存储器，以及提醒服务模块和汽车运动状态检测模块。提醒服务模块包括语音模块，显示模块和扬声器。汽车运动状态检测模块包括加速度传感器、磁传感器和陀螺仪等运动传感器。
图8为根据本发明一种可能的实施方式提供的传感器12的结构图。如图8所示，传感器11包括光线检测模块、蓝牙模块和MCU(Micro Control Unit，中文名称为微控制单元)。
本发明实施例涉及的移动终端11可以包括手机、可穿戴设备(如智能手表、智能手环等)、平板电脑、个人电脑(PC，Personal Computer)、PDA(Personal Digital Assistant，个人数字助理)等。

I/O子系统170用来控制输入输出的外部设备，可以包括其他设备输入控制器171、传感器控制器172、显示控制器173。可选的，一个或多个其他输入控制设备控制器171从其他输入设备130接收信号和/或者向其他输入设备130发送信号，其他输入设备130可以包括物理按钮(按压按钮、摇臂按钮等)、拨号盘、滑动开关、操纵杆、点击滚轮、光鼠(光鼠是不显示可视输出的触摸敏感表面，或者是由触摸屏形成的触摸敏感表面的延伸)。值得说明的是，其他输入控制设备控制器171可以与任一个或者多个上述设备连接。所述I/O子系统170中的显示控制器173从显示屏140接收信号和/或者向显示屏140发送信号。显示屏140检测到用户输入后，显示控制器173将检测到的用户输入转换为与显示在显示屏140上的用户界面对象的交互，即实现人机交互。传感器控制器172可以从一个或者多个传感器150接收信号和/或者向一个或者多个传感器150发送信号。
处理器180是手机100的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器120内的软件程序和/或模块，以及调用存 储在存储器120内的数据，执行手机100的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器180可包括一个或多个处理单元；优选的，处理器180可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器180中。
手机100还包括给各个部件供电的电源190(比如电池)，优选的，电源可以通过电源管理系统与处理器180逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗等功能。
尽管未示出，手机100还可以包括摄像头、蓝牙模块等，在此不再赘述。
