本实施例中，目标物包括物品和/或活体对象。具体活体对象一般指没有行为能力的人，特别是婴儿、儿童。
本实施例的步骤S10可以在车门锁解锁时开始判断，也可以在车辆点火时或点火后开始判断。
在步骤S20中发出一级警报前，车辆可以是行驶状态，也可以直接启动 后不行驶，只要车辆后排座椅存在目标物，且车辆后期熄火就开始一级报警。
在实际的过程中，用户使用车辆时，可能车辆解锁或点火后，在后排放下目标物后又会想到其它事情转而将车辆熄火离开，因此为了避免该情况的发生，不管车辆是否启动行驶了，只要车辆后排有目标物，且车辆点火后又熄火就需要对驾驶员进行提醒。
很显然，本实施例中，在发出警报前首先要监测车辆后排座椅是不是有目标物，只有在有目标物的情况下，才会进行下一步的警报。该过程是提前对车辆后排是否有目标物进行预判，避免了在任何情况下，车辆熄火后均进行报警而对用户产生骚扰的情况。
此外，本实施例的报警方法分为两级警报，在车辆熄火时发出一级警报，该一级警报可以很大程度上减小车辆后排遗留的问题，但是也不能完全避免。二级警报就是在一级警报未产生作用时进行进一步的补充，进而可以基本上完全消除遗留问题。此外，本实施例的一级警报和二级警报之间有很清晰明了的界限，一级警报在车辆熄火时就发出，而二级警报则在车辆熄火，且驾驶员下车，而后排的车门没有被开启的情况下发出。通过界限清晰的一级警报和二级警报，能够最大程度地降低误报警和用户骚扰的概率。
在本发明一个实施例中，参见图2所示，判断车辆的后排座椅是否有目标物的步骤可包括：
S11，判断车辆的后排车门是否在车辆点火前预设时间内或在车辆点火后且开始行驶前曾开启。若是，即，车辆的后排车门在车辆点火前预设时间内曾开启或者在车辆点火后且开始行驶前曾开启，则执行步骤S12。
S12，确定车辆的后排座椅有目标物。
在本实施例中，一般车辆在点火的前会开启车门锁，如果后排需要放东西或者有人员坐下，则会开启车辆的后排车门。因此，可以通过检测点火前车辆的后排座椅的车门是否开启来判断车辆后排座椅是否有目标物。本实施例中，预设时间可以根据实际应用需求进行设置，例如，本实施例的预设时间可以设置为1-5min。当车辆点火前的1-5min内，车辆的后排车门开启，则判断车辆后排座椅处有目标物。
另外，也可能存在驾驶员先点火，然后后排乘客再就坐的情形。这种情况下，车辆在点火后且开始行使前，车辆的后排车门如果开启了，也可以确定车辆后排座椅有目标物。通过充分考虑上述两种情况，能够全面且准确地 判断出车辆后排是否有目标物，以提高预判的精确度。
本实施例中，在检测判断车辆的后排座椅是否有目标物时可通过车身或者控制器中的一个计时器来计时。计时器可以从后排车门开启后开始计时，此时计时器启动计时时刻是后排车门开启时刻。也可以从后排车门开启且关闭后开始计时，此时计时器启动计时时刻是后排车门关闭时刻。到车辆的发动机点火时，如果计时器的计时时间小于或等于该预设时间，则可判断车辆的后排车门在车辆点火前预设时间内曾开启。这里的后排车门，可以是左后门或者右后门中任何一个。在发动机点火前，如果后排车门多次开启关闭，可以设置每开启一次后排车门，计时器重置一次，最终判断以最后一次后排车门开启、计时器启动算。当然，在其它实施例中，也可以设置多次开启时，计时器不重置，以第一次后排车门开启时刻为启动计时时刻。上述计时器计时时间超过该预设时间时，计时器将自动关闭。另外，当车外闭锁成功时，如果计时器仍在运行计时，则计时器自动关闭。
本实施例中，对于车辆后排座椅是否有目标物的判断是根据车辆车门是否开锁进行判断，而该车门是否开锁是车辆中本来具有的传感器检测得到的，其数据会实时的存储在整车控制器中。本实施例中车辆是否熄火也是可以利用车辆现有的传感器得到。而报警装置所需要的声音或灯光也都可以直接利用车辆现有的例如显示屏、语音系统等进行报警。因此，本实施例整体的方法不需要在车辆上增加额外的传感器或感应器，只需要利用原有的车辆的硬件就可以完成，不需要增加车辆硬件设备，也无需改装车辆，减小硬件成本。
在本发明的另一个实施例中，判断车辆的后排座椅是否有目标物的步骤包括：
在车辆点火启动时，通过感应器扫描判断车辆的后排座椅处是否有目标物。
具体地，该实施例中的感应器包括红外感应器和/或摄像头。
在该实施例中，在车辆点火启动时就直接扫描车辆后排座椅处是否有目标物，相比通过对车辆车门是否开启来判断车辆后排座椅是否有目标物，通过感应器直接扫描更直观。
在本发明一个实施例中，一级警报发生在车辆的内部，且一级警报包括视觉提醒信息和/或声音提醒信息。视觉提醒信息包括在车辆的仪表、中控屏或抬头显示器上显示的提示信息。声音提醒信息包括蜂鸣报警声或语音提示 等。一级警报不管是视觉提醒信息还是声音提醒信息，都是设置在车辆内部的，且都可以利用目前现有的车辆的现有的部件来进行报警。
该一级警报是在车辆停车时发生，也就是当车辆停车熄火时，就开始发出一级警报，从而可以很好地提示驾驶人员，以免产生遗漏。具体地，后排遗留提醒中，一级警报中的声音提醒，可以由仪表发出，可以是一声或者多声，持续时间可以是1秒、0.7秒或其它时长。一级警报中的视觉提醒，可以显示在仪表上或者中控大屏上或抬头显示器上，内容可以包括但不限于“Check Rear Seat”、“请检查后排”等，文字可设置特定的显示效果，包括文字颜色(如白色、黄色或者红色等)、文字大小(如2.59、4.31、3.45、1.6mm字高等)、文字闪烁时间(如3.5s或其它时长)和频率(如0.5Hz/1Hz/1.5Hz)等。
在本发明的一个实施例中，参见图3所示，判断车辆的驾驶员是否离开驾驶座位的步骤包括：
S31，判断车辆的驾驶座位一侧的车门是否开启。若是，则执行S32。
S32，判断在驾驶座位一侧的车门开启并关闭后车辆的车门是否上锁。若是，则执行S33。
S33，确定车辆的驾驶员离开驾驶座位。
本实施例中若车辆驾驶座位的一侧的车门开启且上锁，则说明驾驶员有下车离去的意图，且下车离去的意图很明显。
在本发明另一个实施例中，判断车辆的驾驶员是否离开驾驶座位的步骤包括：
通过车辆的驾驶座位内设置的重力感应器检测驾驶座位处的重力变化，根据重力变化判断车辆的驾驶员是否离开驾驶座位。
具体地，在车辆熄火后，重力感应器检测到驾驶座位的重力减轻，从而判断车辆驾驶座位的人员下车离去。当然，此实施例可以作为备选的实施例，当车辆中驾驶员座位配备有重力感应器时可以通过这种方式进行检测判断。而当车辆中驾驶员座位并未配备重力感应器时，则采用S31至S33的步骤判断驾驶员是否离开驾驶座位。
通过上述不同实施例中对于驾驶员是否离开驾驶座位的判断，了解驾驶员是否有离去意图，当驾驶员离去后，则说明车辆后排目标物有被遗留的风险，因此可以开始进行二级警报的启动条件判断，当该启动条件符合时，进 行二级警报。具体地，二级警报的程度可高于一级警报，并且二级警报发生在车辆的外部。二级警报可以包括声音提醒(如语音播报、持续的报警声音等)和/或灯光闪烁。后排遗留提醒中，二级警报中的声音提醒，可以是由车外喇叭或其它扬声器发出的，声音可以持续1.5s、2s、3s、4s、5s或者其它时长，声音共响一声、两声、三声、四声、五声或六声等。二级警报提醒时，可以配合车外四角灯或其它灯具闪烁。闪烁频率可以与声音同步，也可以不同步。闪烁时长和次数可以低于、等于或者多于声音。二级警报的语音播报的声音可大于一级警报的语音提示的声音。
此外，作为本发明的一个实施例，在控制发出一级警报之前，还包括：
获取车辆的一级警报功能的启闭状态，其中所述一级警报功能的启闭状态为默认设置或根据外部输入的用户操作设置；
若一级警报功能处于开启状态，则执行控制发出一级警报的操作。
同样地，在控制发出二级警报之前，还包括：
获取车辆的二级警报功能的启闭状态，其中，二级警报功能的启闭状态为默认设置或根据外部输入的用户操作设置；
若二级警报功能处于开启状态，则执行控制发出二级警报的操作。
本实施例中，一级警报和二级警报可以默认设置或根据外部输入的用户操作设置。一般情况下，默认设置是一级警报功能和二级警报功能常开的状态，每一次车辆启动时就开始了整个系统的检测和报警功能。而外部输入的用户操作设置则可以在车辆处设置开关，开关可以为两个，分别是控制开启和关闭一级警报功能的开关和控制开启和关闭二级警报功能的开关。在一般情况下开关全部处于关闭警报功能的状态。而当监测到车辆的后排座椅有目标物时会自动将开关切换至警报功能开启的状态。驾驶员则可以通过手动选择关闭模板开关，从而只保留一级警报功能或二级警报功能或者全部关闭。
具体地，开关可以设置有文字标识，文字标识可以中文或者英文表示，如：“CPD”、“后排遗留提醒”、“First Warning”、“仪表提示”、“Second Warning”或“鸣笛提示”等。开关可以设置在仪表上，当设置在仪表上时，可以通过仪表触摸屏进行控制。开关也可以设置在方向盘上，通过方向盘按键进行控制。开关还可以设置在中控屏上，当开关设置在中控屏上时，可以通过中控触摸屏直接控制，也可以通过中控屏周围的按键进行控制。开关的显示界面可以是不同的颜色，例如灰色表示开，绿色表示关。当然，颜色可以多样化，灰 色可以替换为白色等暗色类，绿色可以用蓝色等替代。
基于同一技术构思，本发明实施例还提供一种车辆报警控制系统。该车辆报警控制系统可以包括存储器和处理器，存储器内存储有控制程序，控制程序被处理器执行时用于实现上面任意实施例或实施例组合所述的车辆报警控制方法。处理器可以是一个中央处理单元(central processing unit，简称CPU)，或者为数字处理单元等等。处理器通过通信接口收发数据。存储器用于存储处理器执行的程序。存储器是能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何介质，也可以是多个存储器的组合。上述控制程序可以从计算机可读存储介质下载到相应计算/处理设备或者经由网络(例如因特网、局域网、广域网和/或无线网络)下载到计算机或外部存储设备。
车辆报警控制系统提前对车辆后排的目标物进行预判，避免了在任何情况下，车辆熄火后均进行报警而对用户产生骚扰的情况。
该车辆报警控制系统分为两级报警，在车辆熄火时发出一级警报，该一级报警可以很大程度上减少车辆后排遗留的问题，但是也不能完全避免。二级警报就是在一级警报未产生作用时进行进一步的补充，进而可以基本上完全消除遗留问题。此外，本实施例的一级警报和二级警报之间有很清晰明了的界限，一级警报在车辆熄火时就发出，而二级警报则在车辆熄火，且驾驶人员下车，而后排的车门没有被开启的情况下发出二级警报。本车辆报警控制系统中一级警报和二级警报的界限清晰，且能够对于不同的场景和不同用户操作进行一级警报功能和二级警报功能的启闭，从而可以最大程度地降低误报警和用户骚扰的概率，提升用户的使用体验。
基于同一技术构思，本发明实施例还提供一种车辆。该车辆可以包括上面所述的车辆报警控制系统。具体地，该车辆还要包括采集装置和报警装置。采集装置与车辆报警控制系统连接，将采集到的各种信息发送到车辆报警控制系统。报警装置也与车辆报警控制系统连接，该车辆报警控制系统控制报警装置进行报警。采集装置可以包括车辆的各种传感器，例如红外感应器、车门启动感应器、车辆点火/熄火感应器、车辆座椅重力感应器等。而报警装置则可以是声光电中任意一种或多种的组合，可以设置在车辆内部和外部。利用了上述的车辆报警控制系统的车辆可以有效地避免车辆后排物品或成员(特别是小孩)的遗留问题，大大的增加了车辆安全性能，避免危险的发 生。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
