具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种驾驶模式切换方法，图1是根据本发明实施例的驾驶模式切换方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，检测用户设备的状态；
步骤S104，在检测到用户设备的状态为第一预设状态的情况下，将用户设备的工作模式从当前模式切换至驾驶模式；
其中，第一预设状态包括：用户设备的当前放置状态为预设放置状态，未检测到触摸用户设备的触控屏所产生的信号，且用户设备的移动速度超过第一预设阈值，其中，预设放置状态为横屏状态或竖屏状态。
通过上述步骤，采用对用户设备状态的判断的方式，在第一预设状态下降用户设备的工作模式从当前模式切换至驾驶模式，从而解决了相关技术中无法自动开启驾驶模式所导致的问题，实现了驾驶模式的自动切换。
优选地，上述的用户设备包括但并不限于：智能手机、平板电脑，其他具备触控屏的便携式设备也可以采用上述方法进行驾驶模式的自动切换。尤其地，本发明实施例可以应用在无边框、具备触控屏的手机中；在本发明实施例中，检测触摸用户设备的触控屏所产生的信 号的作用是判断是否有用户持握或者触摸操作用户设备，因此，在边框上具有检测用户操作的感应器的用户设备中，这些感应器也可以看成是触控屏的延伸，也应当在本发明实施例的保护范围之内。在本发明实施例中，将采用具备触控屏的手机为例进行描述和说明；例如，手机检测用户设备的状态；并在检测到用户设备的状态为第一预设状态的情况下，将用户设备的工作模式从当前模式切换至驾驶模式。
在本发明实施例中，用户设备的状态可以通过传感器和触摸屏来检测，其中，这些传感器包括但不限于：陀螺仪传感器、重力加速度传感器。而状态的判断以及工作模式的切换可以由用户设备中的处理器进行处理。
上述的预设放置状态是指：预先设置的用户设备的放置状态，例如，用户可以预先设置横屏状态为预设放置状态，也可以预先设置竖屏状态为预设放置状态。
上述的第一预设阈值是指可以用于区别用户正常行走速度的速度阈值，例如：人的步行速度一般低于10公里每小时，则第一预设阈值可以设置为10公里每小时。此外，需要说明的是，在根据本发明实施例的变形方式中，还可以设置用户设备的移动速度的上限阈值，例如：用户的驾驶速度一般低于120公里每小时，则可以设置用户设备在10公里每小时至120公里每小时之间的移动速度，且满足其他的第一预设状态的情况下，将用户设备的工作模式从当前模式切换至驾驶模式。需要说明的是，上述的速度阈值仅为本发明实施例的示例性描述，并不表示在本发明实施例中仅限于上述预设阈值的设置，即，上述第一预设阈值是可以根据需要进行预先设置，或者被用户根据需要进行设置和更改的。
在本发明实施例中所指的工作模式，又称为场景模式。工作模式包括：会议模式、睡眠模式、驾驶模式等，例如，会议模式中，会将铃声和短信通知设置为静音；睡眠模式中，可以将数据服务关闭且将铃声和短信通知设置为静音等。用户设备可以在这些工作模式之间进行切换，且这些工作模式的参数配置也是可以由用户自定义更改的。在本发明实施例中所指的驾驶模式一般是指：接收到的短信自动读出、语音电话自动免提接听等。当然，不同的终端厂商或者设备厂商对驾驶模式的参数设置可能有所不同，然而本发明实施例中并不对驾驶模式的具体参数作任何限制，例如，在某些厂商定义的驾驶模式中，也可能接收的短信并不会自动读出。本发明实施例中所指的当前模式是指：用户设备当前被设置为的工作模式，包括但不限于会议模式、静音模式、睡眠模式等，甚至可能是某一种用于驾驶的模式(例如：用于低速驾驶的模式，用于高速驾驶的模式)。
在本发明实施例中还提供了一种自动切出驾驶模式的方式。例如，在检测到用户设备的状态为第二预设状态的情况下，将用户设备的工作模式从驾驶模式切换至当前模式。
第二预设状态包括：在连续的多个检测周期内检测到用户设备的移动速度低于第二预设阈值。例如，第二预设阈值为3公里每小时；设置在连续的多个检测周期内检测移动速度的方式，是为了防止用户在等红灯、道路暂时拥塞所导致的驾驶模式误切出。另外，在本发明实施例的一些变形方式中，工作模式切出驾驶模式之后，可以根据当前场景，自动切换到其他的工作模式，并不限于切换至驾驶模式之前的当前模式。
还可以通过对触摸屏上触摸信号的检测，判断用户是否在连续的多个检测周期内均在操作用户设备。若用户在多个检测周期内均在操作用户设备，也可以认为用户目前并不在驾驶中。例如，第二预设状态包括：在连续的多个检测周期内检测到触摸用户设备的触控屏所产生的信号。较优地，上述的触摸所述用户设备的触控屏所产生的信号为：触摸用户设备的触控屏的边缘位置所产生的信号，其中，边缘位置的宽度可以根据需要进行定义，例如，可以定义距离边框的距离为5％的用户设备长度(或者宽度)为边缘位置；对于触摸用户设备的触控屏的中心区域(被边缘位置包围的中心区域)，如果没有检测到触摸触控屏边缘位置的触摸信号，则可以认为用户没有手持用户设备，此时可以不进行驾驶模式的切出操作。
可以在连续的多个检测周期中同时检测用户设备的移动速度和触摸信号的方式来判断是否将用户设备的工作模式切出驾驶模式。
自动切换驾驶模式可以设置一个使能开关，用户可以根据需要选择是否开启自动切换驾驶模式的功能，例如，在将用户设备的工作模式切换至驾驶模式之前，判断用户设备上第一使能开关是否为打开状态，其中，第一使能开关用于指示是否启用自动将用户设备的工作模式切换至驾驶模式的功能；在将用户设备的工作模式从当前模式切换至驾驶模式时，可以在判断到第一使能开关为打开状态，且检测到用户设备的状态为第一预设状态的情况下，将用户设备的工作模式从当前模式切换至驾驶模式。
在本发明实施例中也提供了一种手动切出驾驶模式的方式，例如，在将用户设备的工作模式从当前模式切换至驾驶模式之后，接收工作模式切换指令，其中，工作模式切换指令用于指示用户设备将工作模式从驾驶模式切换至当前模式；根据工作模式切换指令，将用户设备的工作模式从驾驶模式切换至当前模式。
优选地，为了避免误操作，并提供给用户直观的使用体验，可以在将用户设备的工作模式从当前模式切换至驾驶模式时，同时提供语音提示或者画面提示，其中，语音提示或者画面提示用于提示用户即将将用户设备的工作模式从当前模式切换至驾驶模式。上述的语音提示或者画面提示中，同时可以申明即将进行驾驶模式切换，还可以申明退出驾驶模式切换的方式；此外，在接收到确认操作之后或者在预设时间之后，才将用户设备的工作模式从当前模式切换至驾驶模式。通过这样的方式，使得用户可以在不需要进行驾驶模式切换的情况下，避免用户设备自动切换到驾驶模式。
优选地，考虑到用户可能使用手机支架观看多媒体应用提供的多媒体节目，因此，为了避免这种情况下的驾驶模式自动切换，可以通过对正在用户设备的***前台运行的应用程序进行判断，例如，第一预设状态还包括：用户设备上***前台正在运行的应用为非多媒体应用。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如 ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
在本实施例中还提供了一种驾驶模式切换装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图2是根据本发明实施例的驾驶模式切换装置的结构框图，如图2所示，该装置包括：检测模块22、第一切换模块24。其中，检测模块22，被设置为检测用户设备的状态；第一切换模块24，耦合至检测模块22，被设置为在检测到用户设备的状态为第一预设状态的情况下，将用户设备的工作模式从当前模式切换至驾驶模式。

本发明的实施例还提供了一种存储介质。在本实施例中，上述存储介质可以被设置为存储用于执行以下步骤的程序代码：

其中，第一预设状态包括：用户设备的当前放置状态为预设放置状态，未检测到触摸用户设备的触控屏所产生的信号，且用户设备的移动速度超过第一预设阈值，其中，预设放置状态为横屏状态或竖屏状态。

可选地，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
为了使本发明实施例的描述更加清楚，下面结合优选实施例进行描述和说明。
已有的技术方案普遍是描述驾驶模式的功能和特点，基本都是手动选取的方式。本发明优选实施例通过连续的多个条件判断，可以实现驾驶模式的自动切换，并且切换更加准确，用户体验更好。
目前手动设置切换为驾驶模式的方式，如果当用户正在驾驶，去操作终端将变得危险且不方便。而如果仅仅通过重力感应器获取加速度的变化来判断是否自动切换驾驶模式，则容易引起误操作。例如，用户开车时将手机放置在包里或者其他地方，再或者终端使用者不是司机而是座客，正在手持手机看视频，按照驾驶模式的设置，此时如果有短信将全部语音读出，不利于保护用户的私人信息，用户体验变差。
为了达到自动并精确的判断驾驶模式的切换，从而自动切换驾驶模式。本发明优选实施例提供了一种检测无边框手机的驾驶模式以及自动切换的***和方法。在本发明优选实施例中，以无边框手机为例进行说明。其中，无边框手机是指触控屏与手机宽度几乎等宽的手机。
本发明优选实施例提供的方案中，该手机包括四个模块：第一个模块被设置为获取屏幕是否处于横屏状态(或者竖屏状态，根据预先设置的状态确定)；第二个模块被设置为判断触控屏(例如，电容触控屏)是否有手握点；第三个被设置为检测终端的水平移动速度，是否在设定的范围值内；第四个模块被设置为获取判断结果并根据结果判断是否要自动切换为驾驶模式。例如，如果前三个模块的条件判断都成立，即当前为横屏(或竖屏)，并且无手握点，移动速度在20公里/小时到200公里/小时之间，此时第四个模块获取到判断结果为成立，***则自动打开手机的驾驶模式，否则，不打开。
同理，***打开驾驶模式后，如果检测到同时满足以下三个条件：速度为0，且处于横屏(或竖屏)，并且边框处有手握点并且手握时间超过用户预设的时间值，则判断处于结束驾驶的状态，此时自动关闭驾驶模式。并且，***提供一个可以打开和关闭自动切换驾驶模式的开关，默认为打开。
下面结合附图对本发明优选实施例进行描述和说明。
一、自动切换驾驶模式的检测及实现过程
本优选实施例提供的切换驾驶模式的条件包括：获取当前手机为横屏(或竖屏)、无手握、移动速度在设定的范围内。判断及切换方法的流程图如图3所示。
下面对三个条件的判断分别进行描述和说明。
条件一，获取当前手机为横屏(或竖屏)
获取终端的横竖屏状态。终端是否处于横竖屏状态可由终端的操作***获取，***有判断横竖屏的函数，获取返回值即可得到当前的横竖屏状态。
条件二，检测终端是否处于手握状态
终端有无手握可以通过触控屏检测有无手握点来判断；由于无边框手机(或者边框较窄的手机)的特点，当终端有手握时，触控屏的屏幕边框边缘部分或屏幕主区域会有触点。而只要检测到任何一个部分有触点，则条件判断不通过。下面将说明如何检测是否有触点以及获取触点位置的方法。
1)我们通常所说的电容屏，包括触摸屏和触摸集成电路(Integrated Circuit，简称为IC)芯片。触摸屏也就是我们手触摸操作的透明部分；触摸IC芯片，其作用是当触摸电容屏时，要解析到触点的位置坐标，就是通过这颗芯片去计算处理的。
2)现在平板电脑、手机、车载等基本都是采用投射式电容，电容屏在玻璃表面镀上ITO(即氧化铟锡)制作成横向(水平)与纵向(垂直)电极阵列，这些横向和纵向的电极分别与地构成电容，这样，投射电容就构成了一个轴坐标式的感应单元矩阵：轴坐标式感应单元分立的行和列，以两个交叉的滑条(带传感功能)实现X轴滑条和Y轴滑条来检测每一格感应单元的电容变化。当手指触摸到电容屏时，手指的电容将会叠加到屏体电容上，使屏体电容量增加。
3)在触摸检测时，电容屏依次分别检测横向与纵向电极阵列，根据触摸前后电容的变化，分别确定横向坐标和纵向坐标，然后组合成平面的触摸坐标。电容的扫描方式，相当于把触摸屏上的触摸点分别投影到X轴和Y轴方向，最后组合成触摸点的坐标。解析的过程由触摸IC芯片来完成，而终端的操作***的驱动会获取到此坐标。
4)***对获取到的触摸坐标进行如下判断：
a)，如图4所示，黑色实线的边框代表手机的整个屏幕区域。如果此时获取到屏幕为竖屏状态，则判断触点坐标的X轴距离也就是触点到终端左边缘的距离，大于零小于整个触摸屏宽度的5％或大于整个触屏宽度的95％小于100％，则获取到触点是位与边框处的两侧，如果触点的X轴距离为整个触摸屏宽度的5％到95％之间，则获取到触点是在屏幕的主区域内操作。百分比的计算通过触点的像素点来判断，例如以手机的屏幕分辨率是1280*720为例，也就是说屏幕的每一个长度的方向上都有1280个像素点，而每一个宽度方向上都720个像素点.如果此时触点的像素点的X轴方向也就是宽度方向是720*5％＝36以内，或者是720*95％＝684以外，则说明触点是在边框的两侧，如果是大于36小于684，则说明触点是在屏幕的主区域。
b)，如图5所示，黑色实线的边框代表手机的整个屏幕区域。如果此时获取到的屏幕为横屏状态，则判断触点坐标的Y轴距离，就是触点坐标到终点下边缘的距离，同上，如果距离大于零小于整个触摸屏宽度的5％或大于整个触屏宽度的95％小于100％，则获取到触点是位与边框处的上下两侧，如果触点的Y轴距离为整个触摸屏宽度的5％到95％之间，则获取到触点是在屏幕的主区域内操作。百分比的计算根据触点的像素点的Y轴方向来判断，同样以1280*720的分辨率为例，在横屏状态下，Y轴方向的像素点的5％和95％，同样也是720*5％＝36,720*95％＝684。
条件三，获取终端当前的移动速度，并判断是否在设定的范围值内。
加速度传感器是智能终端非常普遍的配置，因此移动速度可以通过加速度传感器的值，积分一次即获取速度。以速度值大于20公里/小时小于200公里/小时为例，如果得到的速度值大于20公里/小时小于200公里/小时，则条件判断成立。
其中，加速度积分求速度的公式如下：
v＝∫a(t)dt，其中，a表示加速度，t表示时间。
在进行上述三个条件判断之后，获取这些判断值，如果根据判断值判断到同时满足以上三个条件，则自动切换驾驶模式。也就是，触发自动切换驾驶模式的条件就是当判断为横屏(或竖屏)，并且屏幕边框处或主区域内均无手握点，速度在20公里/小时到200公里/小时之间。在本发明优选实施例的驾驶模式中，来电和短信等自动转成语音播放，并且将语音提示是否需要导航。
二、结束驾驶模式的检测及实现过程
当自动切换到驾驶模式后，***也提供自动检测并结束驾驶模式的方法。例如，结束驾 驶模式的触发条件可以是：
1)终端检测到水平移动速度为零；
2)边框处有手握点，且从检测到手触点时启用计时器，例如，时间超过1分钟则判断此时处于驾驶结束状态。手触时间的长度，用户可以自行设定，例如，20秒、40秒、1分钟或2分钟等均是可选值。
以上两个条件的判断方法，可以参照前述说明，在此将不再赘述。如果以上两个条件均成立，则判断处于结束驾驶的状态，此时可以自动关闭驾驶模式。
同时，***提供打开和关闭自动切换驾驶模式的开关，以上处理流程仅在打开此开关时有效，当用户不需要***自动检测驾驶模式时，则关闭此开关即可.如图6所示，***首先判断终端的自动切换驾驶模式的开关是否为开，如果已打开，则进行上述的自动检测流程，如果开关为关，则结束。
下面对本发明优选实施例的应用场景进行说明。
1、触发切换驾驶模式：
用户的终端以预先设置为打开自动切换驾驶模式的功能。当用户准备驾驶汽车时，将手机横屏放置于手机架上或者汽车驾驶台的合适位置，此时手机就获取到了屏幕处于横屏(或竖屏)的状态信息；当用户开始驾驶汽车时，手机继续获取到此时符合没有手握点的条件，当汽车启动，手机获取当前的移动速度大于等于20公里/小时，则三个条件均判断通过，此时手机将自动切换到驾驶模式，语音提示用户是否需要打开导航，用户语音控制回答是，则直接开启导航，并且将短信和来电均转换为语音模式。具体的驾驶模式下的功能，因终端不同而可能有少许的差异。
2、结束驾驶模式
当用户停止驾驶，此时，***获取到移动终端的速度变为0，并且判断手机边框处有无手握点，如果检测到边框出有手握点，并且手触时间大于用户预设的时间，例如1分钟，则得知此时处于驾驶结束状态，从而自动关闭退出驾驶模式。
如果***获取到移动终端速度为零时，且边框处无手触点，但是屏幕的主区域有手触点，则判断此时可能是用户在等红绿灯等状态下主动操作屏幕的行为，不符合结束驾驶状态，则不退出驾驶模式。
需要说明的是，以上方案中的检测条件中的是否有手握点，也可以替换为，仅检测无边框的周围是否有手触点。因为如果正常使用手机，一般情况下，边框处一定会有手触点，无边框手机(或者边框窄的手机)刚好能做到判断这一条件。并且，在处于驾驶模式的过程中，也可以增加一个判断条件：当自动切换为驾驶模式后，如果检测到屏幕的主区域内有手触点，但是手机仍然处于横屏状态，则***判断出，此时是用户在驾驶状态下主动操作手机，则不关闭驾驶模式。如何检测触点处于边框周围或者是屏幕主区域前面已经进行说明，此处不再 赘述。
综上所述，通过本发明的上述实施例或者优选实施例，通过连续条件的检测判断，做到准确判断是否处于驾驶状态，从而自动切换为驾驶模式。在上述实施例中，终端获取到处于横屏(或竖屏)且无手握点，并且速度在预设的范围值内，则说明已经处于驾驶状态，此时终端自动切换为驾驶模式，语音询问用户是否需要打开导航，并且所有来电和短信均转换为语音模式；而当终端获取到移动速度为零，并且手机边框处有手握点且手触时间超过用户设定的时间值，则自动关闭驾驶模式。整个过程用户可以无需任何手动操作，方便安全。
显然，本领域的技术人员应该明白，上述的本发明实施例的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明实施例不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
