针对传统行车记录仪使用便利性不高的缺陷，以下提供一种解决该缺陷的智能车载终端触发系统和方法。在以下说明中，智能车载终端为具有拍摄功能的终端设备，例如行车记录仪、智能汽车后视镜等等。
图1为一个实施例的智能车载终端触发系统示意图。
一种智能车载终端触发系统，包括输入设备100和智能车载终端200。输入设备100和智能车载终端200通过蓝牙低能耗技术通信连接。
输入设备100用于识别输入事件，产生与输入事件相对应的广播信息，通过预建立的蓝牙信任通信接口发送广播信息。图2为一个实施例的输入设备模块示意图。输入设备100可以包括识别模块110、广播生成模块120和第一通信模块130。识别模块110用于识别输入事件，广播生成模块120用于产生与输入事件相对应的广播信息，第一通信模块130用于通过预建立的蓝牙信任通信接口发送广播信息。其中，广播信息用于驱使智能车载终端200实时生成图像数据。生成图像数据后，智能车载终端200还可以将图像数据存储于本地存储介质。图像数据包括从记载有行车情况的视频数据中生成的图片和视频中的至少一种。
实时生成图像数据可以理解为在极短时间内开始生成图像数据，以通俗的说法可以理解为抓拍。
输入设备100为人机交互设备，主要用于人机交互。用户可以通过对输入设备100进行输入操作从而形成输入事件，输入设备100根据用户的 输入操作/事件而响应。具体地，输入设备100可以是按键设备、按钮设备、触摸屏设备、摇杆等通过识别用户动作而响应的设备。
当输入设备100为按键设备时，用户对输入设备100进行输入操作就会形成按键事件；当输入设备100为按钮设备时，用户对输入设备100进行输入操作就会形成按钮事件；当输入设备100为触摸屏设备时，用户对输入设备100进行输入操作就会形成触摸屏事件；当输入设备100为摇杆设备时，用户对输入设备100进行输入操作就会形成摇杆事件。以输入设备100是按键设备为例，按键设备用于识别按键事件，产生与按键事件相对应的广播信息，通过预建立的蓝牙信任通信接口发送广播信息。
对于输入设备100而言，不同的输入操作，可能会形成不一样的输入事件，从而导致输入设备100识别出来后做出不一样的响应。
以输入设备100是按键设备为例，该按键设备可以包括一个按键，也可以包括多于一个的按键。为了提升便利性，本实施例中按键设备可以只包括一个按键。同一按键的按键事件可以包括两种，一种为短按事件，另一种为长按事件。短按事件定义为按键的按下时长小于第一预设时长(例如3秒)的按键事件，长按事件定义为按键的按下时长大于第三预设时长(例如5秒)的按键事件。通常而言，通过对按键进行软件程序上的去抖处理，使得用户按下按键马上松开可以识别为短按事件，用户持续按下按键可以识别为长按事件(从按键松开后确认)。
又以输入设备100是触摸屏设备时为例，该触摸屏设备可以包括触摸屏，通过识别用户在触摸屏操作的点或轨迹来识别触摸屏事件。例如，用户的手指触按触摸屏上的点可以识别为触按事件，用户的手指在触摸屏上滑动以形成滑动轨迹可以识别为滑动事件。当然，触按事件也可以好像上述的按键事件一样，包括短触按事件和长触按事件，也即触摸屏设备可以存在虚拟的按键，该虚拟按键和也可以理解为上述按键设备的按键，在此不再赘述。
识别模块110识别输入事件后，广播生成模块120产生与输入事件相对应的广播信息。不一样的输入事件，通常产生不一样的广播信息。以输入设备100是按键设备为例，按键事件可以包括两种，一种为短按事件， 另一种为长按事件。以下举例描述广播生成模块120如何响应识别模块110生成相应的广播信息。
当识别模块110识别短按事件后，广播生成模块120产生与短按事件相对应的广播信息，该广播信息可以用于驱使智能车载终端200实时生成图片，将所述图片存储于本地存储介质。实时生成图片可以理解为在极短时间内开始生成图片，以通俗的说法可以理解为抓拍图片。
当识别模块110识别长按事件后，广播生成模块120产生与长按事件相对应的广播信息，该广播信息可以用于驱使智能车载终端200实时生成视频，将所述视频存储于本地存储介质。实时生成视频可以理解为在极短时间内开始生成视频，以通俗的说法可以理解为抓拍视频。
当然，当输入设备100是触摸屏设备时，也可以通过识别短触按事件和长触发事件分别生成广播信息驱使智能车载终端200生成图片和视频；当输入设备100是按钮设备和摇杆设备等其他输入设备时也类似，在此不再深入描述。
输入设备100还包括显示模块，显示模块根据输入事件进入相应的显示模式。例如，识别模块110如果识别出短按事件，则显示模块进入第一显示模式；识别模块110如果识别出长按事件，则显示模块进入第二显示模式。第一显示模式和第二显示模式应该有所区别，以显示模块为LED灯为例，第一显示模式可以为灯闪一次，第二显示模式可以为灯闪多次；或者，第一显示模式可以为灯闪一次，第二显示模式可以为常亮。
当广播生成模块120生成广播信息后，第一通信模块130用于通过预建立的蓝牙信任通信接口发送广播信息。
输入设备100的第一通信模块130与智能车载终端200的第二通信模块210(请结合图3)可以形成蓝牙连接。第一通信模块130和第二通信模块210可以皆为蓝牙模块，所述预建立的蓝牙信任通信接口，可以理解为第一通信模块130已经预先和第二通信模块210进行过蓝牙配对而形成的通信接口。例如，输入设备100和智能车载终端200在出厂之前就进行过预先蓝牙配对，或者输入设备100和智能车载终端200到了用户手中用户再将其蓝牙配对。经过一次蓝牙配对的输入设备100和智能车载终端 200，就相当于预建立了蓝牙信任通信接口，这样输入设备100和智能车载终端200在下一次进行蓝牙连接时可以直接建立信任连接，不再进行蓝牙配对。
因此在广播信息中，通常还会包括输入设备100的唯一识别的特征信息，例如物理地址(MAC)和标识符(ID)中至少一种，这样智能车载终端200在预先蓝牙配对时就可以将其加入信任列表，下次连接时可以识别并直接自动建立连接。
为了最大限度地降低功耗，第一通信模块130和第二通信模块210之间采用蓝牙低能耗技术(BLE)。BLE技术采用可变连接时间间隔，这个间隔根据具体应用可以设置为几毫秒到几秒不等。另外，因为BLE技术采用非常快速的连接方式，因此平时可以处于“非连接”状态(Standby，待机状态)以降低能耗，此时链路两端相互间只是知晓对方，只有在必要时才开启链路，然后在尽可能短的时间内关闭链路。
因此，输入设备100在不需要发送广播信息的时候可以处于待机状态，在识别出输入事件后，输入设备100从待机状态切换到广播状态以发送广播信息。输入设备100在发送广播信息期间，通常是在预设的广播时长内周期性发送广播信息。例如，以100毫秒为一周期，在识别出短按事件后，在500毫秒内发送5次广播信息；又例如，以100毫秒为一周期，在识别出长按事件后，在15秒内发送150次广播信息。
输入设备100在发送完广播信息后，可以从广播状态切换到待机状态，以节约能耗。
广播信息还可以包括输入事件代码和电池剩余电量中的至少一种。输入事件代码用于区分不同的输入事件，以按键事件为例，可以以1表示短按事件，以2表示长按事件；而每个输入事件都代表着不同的指令功能，例如短按事件代表生成图片的指令功能，长按事件代表生成视频的指令功能，智能车载终端200响应于该输入事件代码所对应的功能指令并进行相应的动作。电池剩余电量为输入设备100的电池剩余电量信息，当智能车载终端200从广播信息中获取到该电池剩余电量信息，并在所述电池剩余电量低于预设电量值时发出告警信息。例如，当电池剩余电量低于总电量 的10％时，智能车载终端200可以通过声音警告等形式向车主发出提示，提示车主为输入设备100充电或更换电池。
在BLE技术中，通常广播信息具有以下的数据结构：
Preamble Access Address PDU CRC
1(字节) 4(字节) 2-39(字节) 3(字节)
0x25 0x8E89BED6    
Preamble为前同步码，Access Address为访问地址，PDU为有效载荷数据，CRC为校验码。
PDU数据具有以下的数据结构：
Figure PCTCN2015098798-appb-000001
其中Header为数据头，Payload为载荷数据。Payload分为两部分，AdvA为广播地址，AdvData为广播数据。Header通常包括广播类型信息，例如：
ADV_IND:可连接无定向广播
ADV_DIRECT_IND:可连接定向广播
ADV_NONCONN_IND:不可连接无定向广播
ADV_SCAN_IND:可扫描无定向广播
输入设备100的物理地址可以放置于AdvA，而标识符、输入事件代码和电池电量可以放置于AdvData。标识符可以包括通用唯一识别码(UUID，Universally Unique Identifier)。
当然，广播信息可以只包括输入设备的物理地址和输入事件代码，而不需包括标记符和电池电量。又或者，广播信息可以只包括输入设备的物理地址、输入事件代码和电池电量，而不需包括标记符。智能车载终端200接收到广播信息后，验证输入设备100的物理地址与自身存储的物理地址是否匹配，如果匹配则响应输入事件代码生成图像数据，例如响应于短按事件代码而生成图片，响应于长按事件代码而生成视频。
无线“开启”的时间只要不是很短就会令电池寿命急剧降低，因此任 何必需的发送或接收任务需要很快完成。蓝牙低能耗技术中，无线开启时间的第一个技巧是仅用3个“广播”信道搜索其它设备，或向寻求建立连接的设备宣告自身存在。相比之下，标准蓝牙技术使用了32个信道。这意味着蓝牙低能耗技术扫描其它设备只需“开启”0.6至1.2ms时间，而标准蓝牙技术需要22.5ms时间来扫描它的32个信道。所以蓝牙低能耗技术定位其它无线设备所需的功耗要比标准蓝牙技术低10至20倍。
因此，输入设备100采用BLE技术中的广播信息与智能车载终端200进行通信，使得输入设备100和智能车载终端200之间的通信既能实现低能耗，又能使得智能车载终端200快速获取指令和做出响应，极大地提高用户体验和使用便利性。
智能车载终端200用于通过上述蓝牙信任通信接口接收输入设备100所发送的广播信息；响应于广播信息实时生成图像数据，并将图像数据存储于本地存储介质。
图3为一个实施例的智能车载终端模块示意图。智能车载终端200可以包括第二通信模块210、图像生成模块220和存储模块230。第二通信模块210用于通过上述蓝牙信任通信接口接收输入设备100发送的广播信息；图像生成模块220用于响应于所述广播信息实时生成图像数据；存储模块230将图像数据存储于本地存储介质。本地存储介质，例如可以是硬盘或者闪存之类的存储介质。存储介质可以是以固定的形式设置于智能车载终端200中，也可以是可移动的形式，例如存储介质可以是可移动硬盘或可插拔闪存等等。
所述图像数据可以包括从记载有行车情况的视频数据中生成的图片和视频中的至少一种。通常而言，在一次生成中，生成的图像数据只包括图片或只包括视频。当然，不排除图像数据既包括图片也包括视频的情况。
在本实施例中，当输入设备100识别出上述短按事件或短触按事件时，智能车载终端200根据这些输入事件相应的广播信息而响应生成图片；当输入设备100识别出上述长按事件或长触按事件时，智能车载终端200根据这些输入事件相应的广播信息而响应生成视频。以输入设备100为按键设备时为例做以下描述。
所述图片包括：在智能车载终端200接收到广播信息那刻之前或之后的第二预设时长内视频数据中清晰度最佳的图片。广播信息为短按事件所对应的广播信息。
换言之，所述图片是从视频数据中抓取的。假设智能车载终端300接收到该广播信息那个时刻为A时刻，第二预设时长为a时长，在A时刻之前或之后的a时长内，从智能车载终端300记录的视频数据中抓取清晰度最佳的图片。通常而言，是在A时刻之前的a时长内，从智能车载终端300记录的视频数据中抓取清晰度最佳的图片。这是因为当车主对进行按键设备进行操作时，此时车主想要分享的视频画面可能已经错过，因此可以适当从过去的视频画面中获取图片。例如，通常车主按按键时想要分享的视频画面已经错过，这个错过的时间可以设定1秒内，即a时长为1秒。这样，车主在按按键时，所抓取的图片为按按键那时刻(识别出短按事件的时刻)之前的1秒时间内视频中清晰度最佳的图片。
所述视频包括：根据智能车载终端200接收到广播信息的那刻而确定的一段视频。该广播信息为长按事件所对应的广播信息。
换言之，所述视频也是从视频数据中抓取的。假设智能车载终端300接收到该广播信息那个时刻为A时刻，第四预设时长为b时长，在A-b时刻(例如A为13:00，b为1秒，则A-b时刻为12:59:59，则A+b时刻为13:00:01；下同)开始计时到长按事件结束，所述视频就是抓取自这段时间区段内的视频数据。同样，这是因为当车主对进行按键设备进行操作时，此时车主想要分享的视频画面可能已经错过，因此可以适当从过去的视频画面中获取视频。例如，通常车主按按键时想要分享的视频画面已经错过，这个错过的时间可以设定1秒内，即b时长也为1秒。这样，车主在按按键时，所抓取的视频为按按键那时刻(识别出长按事件的时刻)之前的1秒开始计时的视频数据。
当输入设备100为触摸屏设备时也适用上述实施例，只需将上述的短按事件换成短触按事件、将长按事件换成长触按事件。
图4为一个实施例的智能车载终端触发方法流程示意图。请结合图1～3。
本发明还提供一种智能车载终端触发方法，该方法包括如下步骤：
步骤S110：输入设备100识别输入事件，产生与输入事件相对应的广播信息，通过预建立的蓝牙信任通信接口发送广播信息。
输入设备100可以包括识别模块110、广播生成模块120和第一通信模块130。请结合图2。
输入设备100用于识别输入事件，产生与输入事件相对应的广播信息，通过预建立的蓝牙信任通信接口发送广播信息。图2为一个实施例的输入设备模块示意图。输入设备100可以包括识别模块110、广播生成模块120和第一通信模块130。识别模块110用于识别输入事件，广播生成模块120用于产生与输入事件相对应的广播信息，第一通信模块130用于通过预建立的蓝牙信任通信接口发送广播信息。其中，广播信息用于驱使智能车载终端200实时生成图像数据。生成图像数据后，智能车载终端200还可以将图像数据存储于本地存储介质。图像数据包括从记载有行车情况的视频数据中生成的图片和视频中的至少一种。
实时生成图像数据可以理解为在极短时间内开始生成图像数据，以通俗的说法可以理解为抓拍。
输入设备100为人机交互设备，主要用于人机交互。用户可以通过对输入设备100进行输入操作从而形成输入事件，输入设备100根据用户的输入操作/事件而响应。具体地，输入设备100可以是按键设备、按钮设备、触摸屏设备、摇杆等通过识别用户动作而响应的设备。
当输入设备100为按键设备时，用户对输入设备100进行输入操作就会形成按键事件；当输入设备100为按钮设备时，用户对输入设备100进行输入操作就会形成按钮事件；当输入设备100为触摸屏设备时，用户对输入设备100进行输入操作就会形成触摸屏事件；当输入设备100为摇杆设备时，用户对输入设备100进行输入操作就会形成摇杆事件。以输入设备100是按键设备为例，按键设备用于识别按键事件，产生与按键事件相对应的广播信息，通过预建立的蓝牙信任通信接口发送广播信息。
对于输入设备100而言，不同的输入操作，可能会形成不一样的输入事件，从而导致输入设备100识别出来后做出不一样的响应。
以输入设备100是按键设备为例，该按键设备可以包括一个按键，也可以包括多于一个的按键。为了提升便利性，本实施例中按键设备可以只包括一个按键。同一按键的按键事件可以包括两种，一种为短按事件，另一种为长按事件。短按事件定义为按键的按下时长小于第一预设时长(例如3秒)的按键事件，长按事件定义为按键的按下时长大于第三预设时长(例如5秒)的按键事件。通常而言，通过对按键进行软件程序上的去抖处理，使得用户按下按键马上松开可以识别为短按事件，用户持续按下按键可以识别为长按事件(从按键松开后确认)。
又以输入设备100是触摸屏设备时为例，该触摸屏设备可以包括触摸屏，通过识别用户在触摸屏操作的点或轨迹来识别触摸屏事件。例如，用户的手指触按触摸屏上的点可以识别为触按事件，用户的手指在触摸屏上滑动以形成滑动轨迹可以识别为滑动事件。当然，触按事件也可以好像上述的按键事件一样，包括短触按事件和长触按事件，也即触摸屏设备可以存在虚拟的按键，该虚拟按键和也可以理解为上述按键设备的按键，在此不再赘述。
识别模块110识别输入事件后，广播生成模块120产生与输入事件相对应的广播信息。不一样的输入事件，通常产生不一样的广播信息。以输入设备100是按键设备为例，按键事件可以包括两种，一种为短按事件，另一种为长按事件。以下举例描述广播生成模块120如何响应识别模块110生成相应的广播信息。
当识别模块110识别短按事件后，广播生成模块120产生与短按事件相对应的广播信息，该广播信息可以用于驱使智能车载终端200实时生成图片，将所述图片存储于本地存储介质。实时生成图片可以理解为在极短时间内开始生成图片，以通俗的说法可以理解为抓拍图片。
当识别模块110识别长按事件后，广播生成模块120产生与长按事件相对应的广播信息，该广播信息可以用于驱使智能车载终端200实时生成视频，将所述视频存储于本地存储介质。实时生成视频可以理解为在极短时间内开始生成视频，以通俗的说法可以理解为抓拍视频。
当然，当输入设备100是触摸屏设备时，也可以通过识别短触按事件 和长触发事件分别生成广播信息驱使智能车载终端200生成图片和视频；当输入设备100是按钮设备和摇杆设备等其他输入设备时也类似，在此不再深入描述。
输入设备100还包括显示模块，显示模块根据输入事件进入相应的显示模式。例如，识别模块110如果识别出短按事件，则显示模块进入第一显示模式；识别模块110如果识别出长按事件，则显示模块进入第二显示模式。第一显示模式和第二显示模式应该有所区别，以显示模块为LED灯为例，第一显示模式可以为灯闪一次，第二显示模式可以为灯闪多次；或者，第一显示模式可以为灯闪一次，第二显示模式可以为常亮。
当广播生成模块120生成广播信息后，第一通信模块130用于通过预建立的蓝牙信任通信接口发送广播信息。
输入设备100的第一通信模块130与智能车载终端200的第二通信模块210(请结合图3)可以形成蓝牙连接。第一通信模块130和第二通信模块210可以皆为蓝牙模块，所述预建立的蓝牙信任通信接口，可以理解为第一通信模块130已经预先和第二通信模块210进行过蓝牙配对而形成的通信接口。例如，输入设备100和智能车载终端200在出厂之前就进行过预先蓝牙配对，或者输入设备100和智能车载终端200到了用户手中用户再将其蓝牙配对。经过一次蓝牙配对的输入设备100和智能车载终端200，就相当于预建立了蓝牙信任通信接口，这样输入设备100和智能车载终端200在下一次进行蓝牙连接时可以直接建立信任连接，不再进行蓝牙配对。
因此在广播信息中，通常还会包括输入设备100的唯一识别的特征信息，例如物理地址(MAC)和标识符(ID)中至少一种，这样智能车载终端200在预先蓝牙配对时就可以将其加入信任列表，下次连接时可以识别并直接自动建立连接。
为了最大限度地降低功耗，第一通信模块130和第二通信模块210之间采用蓝牙低能耗技术(BLE)。BLE技术采用可变连接时间间隔，这个间隔根据具体应用可以设置为几毫秒到几秒不等。另外，因为BLE技术采用非常快速的连接方式，因此平时可以处于“非连接”状态(Standby， 待机状态)以降低能耗，此时链路两端相互间只是知晓对方，只有在必要时才开启链路，然后在尽可能短的时间内关闭链路。
因此，输入设备100在不需要发送广播信息的时候可以处于待机状态，在识别出输入事件后，输入设备100从待机状态切换到广播状态以发送广播信息。输入设备100在发送广播信息期间，通常是在预设的广播时长内周期性发送广播信息。例如，以100毫秒为一周期，在识别出短按事件后，在500毫秒内发送5次广播信息；又例如，以100毫秒为一周期，在识别出长按事件后，在15秒内发送150次广播信息。
输入设备100在发送完广播信息后，可以从广播状态切换到待机状态，以节约能耗。
广播信息还可以包括输入事件代码和电池剩余电量中的至少一种。输入事件代码用于区分不同的输入事件，以按键事件为例，可以以1表示短按事件，以2表示长按事件；而每个输入事件都代表着不同的指令功能，例如短按事件代表生成图片的指令功能，长按事件代表生成视频的指令功能，智能车载终端200响应于该输入事件代码所对应的功能指令并进行相应的动作。电池剩余电量为输入设备100的电池剩余电量信息，当智能车载终端200从广播信息中获取到该电池剩余电量信息，并在所述电池剩余电量低于预设电量值时发出告警信息。例如，当电池剩余电量低于总电量的10％时，智能车载终端200可以通过声音警告等形式向车主发出提示，提示车主为输入设备100充电或更换电池。
在BLE技术中，通常广播信息具有以下的数据结构：
Preamble Access Address PDU CRC
1(字节) 4(字节) 2-39(字节) 3(字节)
0x25 0x8E89BED6    
Preamble为前同步码，Access Address为访问地址，PDU为有效载荷数据，CRC为校验码。
PDU数据具有以下的数据结构：
Figure PCTCN2015098798-appb-000002
Figure PCTCN2015098798-appb-000003
其中Header为数据头，Payload为载荷数据。Payload分为两部分，AdvA为广播地址，AdvData为广播数据。Header通常包括广播类型信息，例如：
ADV_IND:可连接无定向广播
ADV_DIRECT_IND:可连接定向广播
ADV_NONCONN_IND:不可连接无定向广播
ADV_SCAN_IND:可扫描无定向广播
输入设备100的物理地址可以放置于AdvA，而标识符、输入事件代码和电池电量可以放置于AdvData。标识符可以包括通用唯一识别码(UUID，Universally Unique Identifier)。
当然，广播信息可以只包括输入设备的物理地址和输入事件代码，而不需包括标记符和电池电量。又或者，广播信息可以只包括输入设备的物理地址、输入事件代码和电池电量，而不需包括标记符。智能车载终端200接收到广播信息后，验证输入设备100的物理地址与自身存储的物理地址是否匹配，如果匹配则响应输入事件代码生成图像数据，例如响应于短按事件代码而生成图片，响应于长按事件代码而生成视频。
无线“开启”的时间只要不是很短就会令电池寿命急剧降低，因此任何必需的发送或接收任务需要很快完成。蓝牙低能耗技术中，无线开启时间的第一个技巧是仅用3个“广播”信道搜索其它设备，或向寻求建立连接的设备宣告自身存在。相比之下，标准蓝牙技术使用了32个信道。这意味着蓝牙低能耗技术扫描其它设备只需“开启”0.6至1.2ms时间，而标准蓝牙技术需要22.5ms时间来扫描它的32个信道。所以蓝牙低能耗技术定位其它无线设备所需的功耗要比标准蓝牙技术低10至20倍。
因此，输入设备100采用BLE技术中的广播信息与智能车载终端200进行通信，使得输入设备100和智能车载终端200之间的通信既能实现低能耗，又能使得智能车载终端200快速获取指令和做出响应，极大地提高用户体验和使用便利性。
步骤S110后，执行步骤S120。
步骤S120：智能车载终端200通过上述蓝牙信任通信接口接收输入设备100所发送的广播信息；响应于广播信息实时生成图像数据，并将图像数据存储于本地存储介质。
图3为一个实施例的智能车载终端模块示意图。智能车载终端200可以包括第二通信模块210、图像生成模块220和存储模块230。第二通信模块210用于通过上述蓝牙信任通信接口接收输入设备100发送的广播信息；图像生成模块220用于响应于所述广播信息实时生成图像数据；存储模块230将图像数据存储于本地存储介质。本地存储介质，例如可以是硬盘或者闪存之类的存储介质。存储介质可以是以固定的形式设置于智能车载终端200中，也可以是可移动的形式，例如存储介质可以是可移动硬盘或可插拔闪存等等。
所述图像数据可以包括从记载有行车情况的视频数据中生成的图片和视频中的至少一种。通常而言，在一次生成中，生成的图像数据只包括图片或只包括视频。当然，不排除图像数据既包括图片也包括视频的情况。
在本实施例中，当输入设备100识别出上述短按事件或短触按事件时，智能车载终端200根据这些输入事件相应的广播信息而响应生成图片；当输入设备100识别出上述长按事件或长触按事件时，智能车载终端200根据这些输入事件相应的广播信息而响应生成视频。以输入设备100为按键设备时为例做以下描述。
所述图片包括：在智能车载终端200接收到广播信息那刻之前或之后的第二预设时长内视频数据中清晰度最佳的图片。广播信息为短按事件所对应的广播信息。
换言之，所述图片是从视频数据中抓取的。假设智能车载终端300接收到该广播信息那个时刻为A时刻，第二预设时长为a时长，在A时刻之前或之后的a时长内，从智能车载终端300记录的视频数据中抓取清晰度最佳的图片。通常而言，是在A时刻之前的a时长内，从智能车载终端300记录的视频数据中抓取清晰度最佳的图片。这是因为当车主对进行按键设备进行操作时，此时车主想要分享的视频画面可能已经错过，因此可以适当从过去的视频画面中获取图片。例如，通常车主按按键时想要分享 的视频画面已经错过，这个错过的时间可以设定1秒内，即a时长为1秒。这样，车主在按按键时，所抓取的图片为按按键那时刻(识别出短按事件的时刻)之前的1秒时间内视频中清晰度最佳的图片。
所述视频包括：根据智能车载终端200接收到广播信息的那刻而确定的一段视频。该广播信息为长按事件所对应的广播信息。
换言之，所述视频也是从视频数据中抓取的。假设智能车载终端300接收到该广播信息那个时刻为A时刻，第四预设时长为b时长，在A-b时刻(例如A为13:00，b为1秒，则A-b时刻为12:59:59，则A+b时刻为13:00:01；下同)开始计时到长按事件结束，所述视频就是抓取自这段时间区段内的视频数据。同样，这是因为当车主对进行按键设备进行操作时，此时车主想要分享的视频画面可能已经错过，因此可以适当从过去的视频画面中获取视频。例如，通常车主按按键时想要分享的视频画面已经错过，这个错过的时间可以设定1秒内，即b时长也为1秒。这样，车主在按按键时，所抓取的视频为按按键那时刻(识别出长按事件的时刻)之前的1秒开始计时的视频数据。
当输入设备100为触摸屏设备时也适用上述实施例，只需将上述的短按事件换成短触按事件、将长按事件换成长触按事件。
上述的智能车载终端触发系统和方法，输入设备识别输入事件后，发送广播信息；通过蓝牙低能耗技术与输入设备通信的智能车载终端，接收广播信息并响应生成图像数据。因此，用户可以操作输入设备而使得智能车载终端可以自行生成图像数据，例如生成图片或小段视频，提高了使用便利性；输入设备和智能车载终端是通过蓝牙低能耗技术连接的，并且输入设备使用广播信息来发送相关的指令，使得输入设备和智能车载终端之间的通信既能实现低能耗，又能使得智能车载终端快速获取指令和做出响应，极大地提高用户体验和使用便利性。
