【具体实施方式】
为了使本发明实施例的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明实施例，并不用于限定本发明实施例。
此外，下面所描述的本发明实施例各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
实施例一：
请参考图1，图1是本发明实施例一提供一种多媒体播放状态切换方法的流程示意图。如图1所示，本发明实施例的方法，包括以下步骤：
S11、获取当前车辆状态切换信息；
在步骤S11中，所述当前车辆状态切换信息包括行车状态与驻车状态之间相互切换。此处，获取能够评价当前车辆行驶状态的信息，并将该获取信息和车辆的行车状态以及驻车状态建立起映射关系，得到当前车辆状态切换信息。
在本实施例中，可以根据车辆刹车系统信息，获取当前车辆状态切换信息。此处的车辆刹车系统包括脚刹车系统和手刹车驻车系统，因此，车辆刹车系统信息既可以来源于脚刹车系统，又可以来源于手刹车驻车系统。脚刹车系统或手刹车驻车系统将来自于踏板、手刹、刹车泵、真空助力泵、刹车钳、刹车盘等动作信息传输至分析系统，由分析系统根据评价当前车辆行驶状态的标准得出获取信息和车辆的行车状态以及驻车状态建立起映射关系。比如，当该获取信息是刹车时间，如果刹车时间超过预设时间，则将当前车辆状态是驻车状态；如果刹车时间低于预设时间，则将当前车辆状态是行车状态。具体的，刹车传感器采集当前车辆的刹车信息，分析系统对该刹车信息进行分析，当车辆的刹车或者驻车超过30秒时，分析系统将此时的车辆状态定义是驻车状态。当车辆的刹车或者驻车低于30秒时，分析系统将此时的车辆状态定义是行车状态。又比如压力传感器采集真空助力泵的压力信息，分析系统对该压力信息进行分析，当该压力信息在预 设时间内持续高于预设值，分析系统将此时的车辆状态定义是行车状态。当该压力信息在预设时间内持续低于预设值，分析系统将此时的车辆状态定义是驻车状态。此处，当然还可以通过设置在各个刹车系统内的传感器以得知当前车辆状态。
除了在车辆的刹车系统上获取当前车辆状态切换信息，在本实施例中，还可以根据车辆速度信息，获取当前车辆状态切换信息。此处，如果速度超过预设数值，则车辆状态是行车状态；如果速度低于预设数值，则车辆状态是驻车状态。车辆速度信息的获取可以来源设置于车辆上的速度传感器，也可以来源于导航定位系统。其中，此处的导航定位系统可以是车辆自身携带的车载导航系统，也可以来源于用户随身携带的智能手机中导航系统或者APP导航软件。
在本实施例中，当前车辆状态切换信息的获取来源除了基于车辆状态信息的判断来获取，还可以来源于用户对当前车辆行驶状态的判断。比如，在驾驶员的驾驶位附件设置一图像获取装置，该图像获取装置获取驾驶员对当前车辆状态判断的手势。比如，驾驶员用手画一横，该图像获取装置获取该手势，并将该手势解析是“当前车辆状态是行车状态”。驾驶员用手画一个圆圈，该图像获取装置将该手势解析是“当前车辆状态是驻车状态”。
进一步的，本实施例所提供的关于获取当前车辆状态切换信息的方式是多种多样的。只要存在能够获取评价当前车辆行驶状态的信息，并将该获取信息和车辆的行车状态以及驻车状态建立起映射关系的方式，均落入本发明实施例构思保护范围之内。
S12、根据所述当前车辆状态切换信息，将当前多媒体播放状态切换至与所述切换信息对应的多媒体播放状态。
在步骤S12中，所述多媒体播放状态的信息包括播放音视频文件、 播放音视频文件中的音频内容以及播放音频文件。此处的播放音视频文件采用AVI、ASF、WMV、MPEG、AVS、FLV、MKV、MOV、3GP、MP4、MPG等等其他格式文件，播放音频文件采用MP3、AAC、WAV、MP2、MPC等等其他格式文件。
在本实施例中，从步骤S11得出当前车辆状态由行车状态切换为驻车状态，则切换至播放音视频文件；从步骤S11得出当前车辆状态由驻车状态切换为行车状态，则切换至播放音视频文件中的音频内容或者切换至播放音频文件。
本实施例提供的方法能够根据当前车辆状态，切换至对应的多媒体播放状态。比如，本实施例提供的方法将播放装置切换至播放音视频文件中的音频内容或者切换至播放其他音频文件，使处于行车状态的司机，在不影响错过某段视频的内容情节的同时，又能够目注当前驾驶路面，从而提高了驾驶安全性和用户体验感。本实施例提供的方法将播放装置切换至播放音视频文件，使处于驻车状态的司机，可以利用驻车时枯燥的时间自我娱乐，从而提高用户体验感。
实施例二：
请参考图2，图2是本发明实施例二提供一种多媒体播放状态切换方法的流程示意图。如图2所示，在本实施例中，该方法具体包括以下步骤：
S21、获取当前车辆状态切换信息；
本实施例的步骤S21的实施方式按照实施例一中步骤S11的实施方式来实施，在此不必赘述。
S22、判断所述当前车辆状态切换信息和车辆即时响应信息之间的优先权；
在本实施例的步骤S22中，此处的车辆即时响应信息包括来电接 听事件、导航语音提醒事件、闹钟提醒事件。其中，上述事件的优先权级别从高到底依次是：来电接听事件、当前车辆状态切换信息、导航语音提醒事件、闹钟提醒事件。上述事件的优先权是预先设定的，用户可以根据自己的情况自行调节上述事件的优先权级别。
S23、根据优先权的判别结果，切换至相应的事件。
在本实施例的步骤S23中，如果所述当前车辆状态切换信息的优先权高于当前车辆即时响应信息的优先权，则将当前多媒体播放状态切换至与所述切换信息对应的多媒体播放状态。
此处的多媒体播放状态的信息包括播放音视频文件、播放音视频文件中的音频内容以及播放音频文件。此处的播放音视频文件采用AVI、ASF、WMV、MPEG、AVS、FLV、MKV、MOV、3GP、MP4、MPG等等其他格式文件，播放音频文件采用MP3、AAC、WAV、MP2、MPC等等其他格式文件。
在本实施例中，从步骤S21得出当前车辆状态由行车状态切换为驻车状态，从步骤S22得出当前车辆即时响应信息拥有最高优先权，则切换至播放音视频文件；从步骤S21得出当前车辆状态由驻车状态切换为行车状态，从步骤S22得出当前车辆即时响应信息拥有最高优先权，则切换至播放音视频文件中的音频内容或者切换至播放音频文件。
本实施例提供的方法能够根据当前车辆状态，切换至对应的多媒体播放状态。比如，本实施例提供的方法将播放装置切换至播放音视频文件中的音频内容或者切换至播放音频文件，使处于行车状态的司机，在不影响错过某段视频的内容情节的同时，又能够目注当前驾驶路面，从而提高了驾驶安全性和用户体验感。本实施例提供的方法将播放装置切换至播放音视频文件，使处于驻车状态的司机，可以利用 驻车时枯燥的时间自我娱乐，从而提高用户体验感。
在本实施例的步骤S23中，如果所述当前车辆状态切换信息的优先权低于当前车辆即时响应信息的优先权，则切换至当前车辆即时响应信息对应的事件。
本实施例通过判别各类事件的优先权关系，从而使各类事件能够有条不紊地得以执行。
实施例三：
作为本发明实施例又一方面，本发明实施例三提供了一种多媒体播放状态切换装置。请参考图3，图3是本发明实施例三提供的一种多媒体播放状态切换装置3的示意图。如图3所示，多媒体播放状态切换装置3包括：
获取单元31，用于获取当前车辆状态切换信息，
切换单元32，用于根据所述当前车辆状态切换信息，将当前多媒体播放状态切换至与所述切换信息对应的多媒体播放状态。
在本实施例中，所述当前车辆状态切换信息包括行车状态与驻车状态之间相互切换。此处，获取单元31获取能够评价当前车辆行驶状态的信息，并将该获取信息和车辆的行车状态以及驻车状态建立起映射关系，得到当前车辆状态切换信息。
在本实施例中，可以根据车辆刹车系统信息，获取当前车辆状态切换信息。此处的车辆刹车系统包括脚刹车系统和手刹车驻车系统，因此，车辆刹车系统信息既可以来源于脚刹车系统，又可以来源于手刹车驻车系统。脚刹车系统或手刹车驻车系统将来自于踏板、手刹、刹车泵、真空助力泵、刹车钳、刹车盘等动作信息传输至分析系统，由分析系统根据评价当前车辆行驶状态的标准得出获取信息和车辆的行车状态以及驻车状态建立起映射关系。比如，当该获取信息是刹 车时间，如果刹车时间超过预设时间，则将当前车辆状态是驻车状态；如果刹车时间低于预设时间，则将当前车辆状态是行车状态。具体的，刹车传感器采集当前车辆的刹车信息，分析系统对该刹车信息进行分析，当车辆的刹车或者驻车超过30秒时，分析系统将此时的车辆状态定义是驻车状态。当车辆的刹车或者驻车低于30秒时，分析系统将此时的车辆状态定义是行车状态。又比如压力传感器采集真空助力泵的压力信息，分析系统对该压力信息进行分析，当该压力信息在预设时间内持续高于预设值，分析系统将此时的车辆状态定义是行车状态。当该压力信息在预设时间内持续低于预设值，分析系统将此时的车辆状态定义是驻车状态。此处，当然还可以通过设置在各个刹车系统内的传感器以得知当前车辆状态。
除了在车辆的刹车系统上获取当前车辆状态切换信息，在本实施例中，还可以根据车辆速度信息，获取当前车辆状态切换信息。此处，如果速度超过预设数值，则车辆状态是行车状态；如果速度低于预设数值，则车辆状态是驻车状态。车辆速度信息的获取可以来源设置于车辆上的速度传感器，也可以来源于导航定位系统。其中，此处的导航定位系统可以是车辆自身携带的车载导航系统，也可以来源于用户随身携带的智能手机中导航系统或者APP导航软件。
在本实施例中，当前车辆状态切换信息的获取来源除了基于车辆状态信息的判断来获取，还可以来源于用户对当前车辆行驶状态的判断。比如，在驾驶员的驾驶位附件设置一图像获取装置，该图像获取装置获取驾驶员对当前车辆状态判断的手势。比如，驾驶员用手画一横，该图像获取装置获取该手势，并将该手势解析是“当前车辆状态是行车状态”。驾驶员用手画一个圆圈，该图像获取装置将该手势解析是“当前车辆状态是驻车状态”。
进一步的，本实施例所提供的关于获取当前车辆状态切换信息的方式是多种多样的。只要存在能够获取评价当前车辆行驶状态的信息，并将该获取信息和车辆的行车状态以及驻车状态建立起映射关系的方式，均落入本发明实施例构思保护范围之内。
在本实施例中，所述多媒体播放状态的信息包括播放音视频文件、播放音视频文件中的音频内容以及播放音频文件。此处的播放音视频文件采用AVI、ASF、WMV、MPEG、AVS、FLV、MKV、MOV、3GP、MP4、MPG等等其他格式文件，播放音频文件采用MP3、AAC、WAV、MP2、MPC等等其他格式文件。
在本实施例中，所述切换单元32包括：
第一切换模块321，用于如果当前车辆状态由行车状态切换为驻车状态，切换至播放音视频文件；
第二切换模块322，用于如果当前车辆状态由驻车状态切换为行车状态，则切换至播放音视频文件中的音频内容或者切换至播放音频文件。
在本实施例中，获取单元31得出当前车辆状态由行车状态切换为驻车状态，则第一切换模块321将当前多媒体播放状态切换至播放音视频文件；获取单元31得出当前车辆状态由驻车状态切换为行车状态，则第二切换模块322将当前多媒体播放状态切换至播放音视频文件中的音频内容或者切换至播放音频文件。
本实施例提供的多媒体播放状态切换装置能够根据当前车辆状态，切换至对应的多媒体播放状态。比如，本实施例提供的多媒体播放状态切换装置将当前多媒体播放状态切换至播放音视频文件中的音频内容或者切换至播放音频文件，使处于行车状态的司机，在不影响错过某段视频的内容情节的同时，又能够目注当前驾驶路面，从而 提高了驾驶安全性和用户体验感。本实施例提供的多媒体播放状态切换装置将当前多媒体播放状态切换至播放音视频文件，使处于驻车状态的司机，可以利用驻车时枯燥的时间自我娱乐，从而提高用户体验感。
