下面以电子设备100是手机，电子设备200是车机为例，对本申请实施例提供的技术方案进行详细说明。
在现有技术中，触控型的车载系统(车机)已经逐渐成为各家厂商车辆的标准配置，但是，由于车载系统的触摸屏无法提供触觉反馈，在驾驶中会占用用户较多的视觉资源，使得用户不能专注于驾驶，影响驾驶安全。此外，用户在驾驶时，也可以选择将手机连接到车机，车机与手机的功能的交互，进一步丰富车载系统的使用。在驾驶车辆的过程中，用户可能会关注车载系统的显示屏，以处理手机接到的通知消息或者以此使用手机更为丰富的娱乐功能。然而，当用户驾驶车辆高速行驶或者处于一些特定的场景下时，例如用户驾驶车辆处于人流密集的路段、用户驾驶车辆经过高危路段、用户在夜间驾驶车辆、用户在恶劣天气驾驶车辆，或者驾驶车辆处于限速路段等场景时，用户应该将更多的精力用于专注驾驶，而不能分散注意力。即，在一些情况下，应该提供一种能够减少车机显示屏所占用的视觉资源及认知资源的用户界面，保障行车安全。
为此，本申请实施例提供了一种显示用户界面的方法，在车机开始工作后，可以自动识别出车辆所处的各种场景，基于不同场景显示不同的用户界面，当车辆所处的场景变换时，可以根据变换的场景显示相应的用户界面。其中，显示的用户界面可以包括第一用户界面和第二用户界面。第一用户界面为不显示部分功能或者显示但不能操作部分功能的用户界面，第二用户界面为显示包含所有功能的用户界面。上述功能包含一些功能和一些功能的某些操作，其中，一些功能可以是以手机软件(application， APP)的方式来呈现。
例如：识别出用户未在驾驶时，车机的触摸屏可以显示第二用户界面。
再例如：识别出用户在驾驶，但处于某些可以不必过于集中注意力的场景时或者说处于某些允许用户进行一些其他稍占用视觉资源或认知资源操作的场景时，即用户处于不必高度集中注意力的场景时，那么车机的触摸屏可以显示第二用户界面。
又例如：识别出用户在驾驶，且处于某些需要高度集中注意力的场景时，车机触摸屏显示第一用户界面。
其中，本申请实施例中显示用户界面的方法可以预配置在车载终端中，使得所有车载终端均采用该方法显示用户界面；也可以根据用户选择，在用户设置后车载终端不采用该显示用户界面的方法。
其中，上述需要高度集中注意力的特定场景例如是用户驾驶车辆高速行驶(可以根据车辆性能确定第一预设速度，判定实时车速大于第一预设速度时为高速行驶)，用户驾驶车辆行驶在处于人流密集的路段(例如：商业中心、旅游景点、学校路段等)时，用户驾驶车辆经过高危路段(例如：连续转弯、高速路、隧道等)时、用户驾驶车辆处于夜间(例如：可以根据太阳落山时间确定、根据光照强度确定等)行驶状态，用户在恶劣天气(例如：浓雾、冰雪天气、雷雨天气等)下驾驶车辆、用户在限速路段(例如：下坡路段、村庄路段、道路交汇路口等)驾驶车辆时等。
有的时候车机并不能准确识别用户此时所处的场景，在手机连接到车机的情况下，也可以结合手机与车机的识别结果，进而更加准确的识别出用户所处场景。比如识别出用户在驾驶，但未处于需要高度集中注意力的场景时，车机的触摸屏可以显示包含所有功能的用户界面。在识别出用户处于需要高度集中注意力的场景时，车机触摸屏显示隐藏或者不允许操作部分功能和/或操作后的用户界面。
在一些实施例中，可能用户开始处于不需要高度集中注意力的场景，并且在车机触摸屏的第二用户界面上操作某些功能，而在操作的过程中，用户进入到了需要高度集中注意力的场景，此时，车机会立即中断当前操作，切换显示第一用户界面，以保证驾驶安全。或者，可以在用户完成当前操作后再进行切换用户界面，以保证用户使用的体验感。对此，本申请实施例并不做具体限定。
如图4所示，为本申请实施例提供的一种切换用户界面的方法的流程图，具体如下：
S401、车机开始工作。
具体的，当用户启动车辆开启驾驶模式后，车机开始显示触摸屏的用户界面，此时判定车机开始工作。一般的，此时的用户界面为默认主页面为即显示包含全部功能的第二用户界面(参见图6所示)。
需要说明的是，本申请实施例并不限制手机是否连接到车机，即手机可以连接到车机，也可以并未与车机连接。此步骤仅考虑车机是否开始工作，而不必考虑手机与车机的连接状况。
在手机未连接到车机的情况下，由车机对场景进行识别。在手机连接到车机的情况下，手机的数据可以与车机进行同步，由车机结合手机采集的数据对用户所处场景进行识别，而后更加精准的显示与该场景相应的用户界面。换言之，车机可以承担手 机全部或部分的数据处理工作，本申请实施例对车机和手机的分工不做限定。
以下步骤，是以车机承担对用户状态和场景进行判断，确定车机触摸屏显示的用户界面为例进行说明的。
S402、车机确定车辆是否处于驾驶状态。若不处于驾驶状态(即处于未被驾驶状态)，则执行步骤S403。若处于驾驶状态，则执行步骤S404。
在一种可能的实现方式中，可以获取车机测得的车辆的时速等信息，确定车辆是否处于行进中，从而确定车辆是否处于驾驶状态。也可以通过车机的全球定位系统(global positioning system，GPS)确定出车机的实时位置，根据实时位置计算出车机的移动速度。而后，判断车机的移动速度是否大于阈值。若车机的移动速度大于阈值，可认为车辆处于驾驶状态。若车机的移动速度不大于阈值，可认为车辆不处于驾驶状态。
可选的，在手机连接车机的情况下，车机也可以获取手机的数据，通过手机内设置的传感器(例如：加速度传感器)来获取手机的移动速度，从而确定车辆是否处于被驾驶状态。
S403、车机触摸屏显示第二用户界面。
具体的，当确定车辆不处于驾驶状态，或者说，此时使用该车辆的用户处于不必高度集中注意力的时候，认为用户此时可以方便的操作车机，那么车机触摸屏就可以在。第二用户界面中以第二预设方式显示第一功能和第二功能，第二预设方式用于表示允许用户操作第一功能和第二功能。第一功能和第二功能构成了车机触摸屏上显示的全部功能，即此时的第二用户界面显示所有的功能供用户选择使用。
如图6所示，示例性的给出了一种触控型车机的用户界面，该用户界面包含显示于左侧的主菜单601和显示于右侧的显示界面602。其中，主菜单601中显示有车机包含的主要功能，显示界面602中的显示内容对应于左侧主菜单601中的每一功能分别显示不同的用户界面。图6中所示的用户界面的主菜单601中示例性的给出了主页、导航、通话、音乐和车控五种功能。一般的，触摸屏会将所有的常用功能显示于主页界面(即选择主菜单601上的“主页”功能后对应显示的显示界面602)，如图6，示例性的给出了当选择主菜单601上的“主页”这一功能后，显示界面602对应显示的用户界面，即主页界面包含了的地图、微信、联系人、电话、娱乐、天气六种常用功能。
可以理解的是车机应该还可以包含其他主要或者常用应用功能可以显示于车机触摸屏，并且，基于触摸操作，可以切换当前的主页界面，以显示更多的常用功能，对此可以参见现有技术，本申请实施例不做具体说明。
之后，用户可以根据需求一步步点击相应的功能进入子菜单，实现最终功能。比如，用户想要利用车机进行通话操作，可以触摸电话图标，进而进入通话界面，之后，可以进行拨号或者电话查询操作，进而实现电话拨打。或者如图7所示，用户通过点击屏幕左侧主菜单601界面上的通话功能，显示界面602对应显示通话界面，在该通话界面中，可以向用户提供拨号操作、联系人搜索和最近联系人列表浏览(此界面在图7中并未示出，可以理解的是可以通过相关操作进入的该功能界面)等 操作。
S404、车机确定车辆处于预设场景或当前车速大于第一预设速度。若车机确定车辆处于预设场景或当前车速大于第一预设速度，则执行步骤S405，若车机确定车辆未处于预设场景且当前车速小于等于第一预设速度，则执行步骤S403。
具体的，可以将车辆处于预设场景或当前车速大于第一预设速度确定为第一预设条件。进而判断当车辆满足第一预设条件时，车机触摸屏显示第一用户界面。
其中，预设场景例如可以是：用户驾驶车辆行驶在处于人流密集的路段(例如：商业中心、旅游景点、学校路段等)时，用户驾驶车辆经过高危路段(例如：连续转弯、高速路、隧道等)时、用户驾驶车辆处于夜间(例如：可以根据太阳落山时间确定、根据光照强度确定等)行驶状态，用户在恶劣天气(例如：浓雾、冰雪天气、雷雨天气等)下驾驶车辆、用户在限速路段(例如：下坡路段、村庄路段、道路交汇路口等)驾驶车辆时等。
对于当前场景是否为上述预设场景，可以为车机根据传感数据或者其它方式进行分析判断得出的结论，具体示例性的给出的五种预设场景的判断方法，详见下文具体描述。
预设场景一：车辆处于人流密集的路段。
在判断用户是否驾驶车辆行驶在人流密集的路段时，可以通过车机和/或手机内的传感器数据来分析。其中，车机至少根据以下至少一项数据判断车辆是否处于人流密集路段：车辆的行驶状态，车辆周围环境的图像或者行驶路线。例如：可以根据车辆的行驶时速确定车辆是否位于人流密集路段。还可以根据车辆的位置，确定车辆是否正在商业中心等人流密集处。
可选的，由于车辆应该具备实时获取车速的能力，车机可以获取一段时间内车速的变化，如果在预设时间段内车辆时速在反复变化，且车速均较小，即车辆在预设时间段内反复制动，则可以确定车辆处于上述人流密集的路段导致车辆不能顺利行驶。
可选的，由于导航软件中包含有各个路段的道路信息，例如：某某商业中心路段、某某旅游景点、学校路段等，而一般这些路段人流都会比较密集。因此，根据车机和/或手机确定出车辆当前的位置，根据当前位置和导航软件中该位置的道路信息，确定车辆是否处于上述的人流密集的路段。
可选的，可以通过车机内的摄像头或车机连接的摄像头，根据摄像头拍摄的车辆周围环境的图像，采用图像分析技术，对车辆外部的环境进行识别，进而确定出车辆是否处于人流密集的路段。其中，可以预设一个数值，比如当车辆周围人数超过10个时，判断车辆处于人流密集的路段。
预设场景二：车辆正在经过高危路段。
在判断用户是否驾驶车辆正在经过高危路段时，可以通过车机和/或手机内的传感器数据来分析。其中，车机至少根据以下至少一项数据判断车辆是否处于高危路段：车辆的行驶路线，行驶状态或者车辆周围环境的图像。例如：可以根据车辆的行驶路线，确定车辆是否正在连续转弯。还可以根据车辆的行驶时速确定车辆是否位于高速路上。还可以根据车辆的行驶路线和行驶时速，确定车辆是否在湿滑路面行驶等。还可以通过光线传感器判断车辆周围的光线，进而确定是否位于隧道中等。
可选的，还可以通过车机内的摄像头或车机连接的摄像头，根据摄像头拍摄的车辆周围环境的图像，采用图像分析技术，对车辆外部的环境进行识别，进而确定出车辆是否处于上述的高危路段中。
可选的，由于导航软件中包含有各个路段的路况数据(例如：急转弯、隧道等)，所以还可以根据手机或车机确定出车辆当前的位置，根据当前位置和导航软件中该位置的路况数据，确定车辆是否处于上述的高危路段。
预设场景三：车辆处于夜间行驶状态。
在判断用户驾驶车辆是否处于夜间行驶状态时，可以通过车机和/或手机内的传感器数据来分析。其中，车机至少根据以下至少一项数据判断车辆是否处于夜间行驶状态：车辆所处的环境光线状况，车辆周围环境的图像或者实时时间。例如：当光照强度低于阈值持续时间超过阈值时，判定用户处于夜间行驶状态。或者，在太阳落山一小时后到太阳升起前一小时这段时间内用户驾驶车辆行驶，则判定用户处于夜间行驶状态。
可选的，可以根据车机和/或手机的摄像头拍摄的周围环境的图像，采用图像分析技术，进而识别出车辆所处环境的光照强度，判断用户是否处于夜间驾驶状态。
可选的，可以根据车机的光线传感器判断车辆周围的光线，并且可以进一步的结合光线持续时间，进而更加准确的确定用户是否处于夜间驾驶状态。
可选的，可以根据当前时段及位置坐标的太阳落山时间后为判断夜间行驶的开始时间，根据太阳升起时间之前为判断夜间行驶的结束时间。比如，某地当前季节太阳升起时间为7:00，太阳落山时间为18:00，则可以定义夜间行驶时段为19:00-次日6:00，用户在这一时段驾驶则为夜间驾驶。
预设场景四：当前天气条件恶劣。
在判断用户是否在恶劣天气下驾驶车辆时，也可以通过手机和/或车机内的传感器数据来分析。其中，车机至少根据以下至少一项数据判断车辆是否行驶于恶劣天气条件下：车辆所处的环境光线状况，周围环境的图像或者天气软件的数据。例如：可以根据车机内的光线传感器等确定车辆周围环境，例如车辆处于浓雾、黑暗中。还可以根据车机内的雨量传感器，确定车辆是否处于雷雨天气中等。
可选的，还可以通过车机内连接的摄像头，根据摄像头拍摄的车辆周围环境的图像，采用图像分析技术，对车辆外部的环境进行识别，进而确定出车辆是否处于上述的恶劣天气中。
可选的，也可以根据通过天气应用软件获取当前的天气情况，进而判断车辆是否处于上述恶劣天气中。
预设场景五：车辆处于限速路段。
在判断用户是否处于限速路段驾驶车辆时，车机至少根据以下至少一项数据进行判断：车辆周围环境的图像，当前道路信息。比如可以通过车机和/或手机内导航软件，确定当前道路信息，进而确定用户是否处于限速路段。一般的特殊路段，比如：下坡路段、村庄路段、道路交汇路口等都会进行车辆限速进而保证行车安全，而导航软件中都会包含特殊路段信息，进而车机可以根据用户车辆的行驶位置确认用户是否处于限速路段。
可选的，也可以通过车机内连接的摄像头，根据摄像头拍摄的车辆周围路段设置的限速标识，采用图像分析技术，确定出车辆是否处于限速路段上。
车机可以根据上述方法获得相应的数据进而判断车辆是否处于预设场景或者处于哪一种或几种预设场景中，进而判断此时用户是否需要高度集中注意力。
车速为影响用户注意力的较大的一种因素，当车速较快时，用户必须集中注意力在车辆驾驶上，因此，设置第一预设速度，用于判断当前车辆是否处于高速驾驶状态。
第一预设速度为根据车辆性能确定或为直接预设置的阈值。在判断用户是否在驾驶车辆高速行驶时，车机可以实时获取测得的车辆的时速等信息，比较实时车速与第一预设速度，从而确定用户是否在驾驶车辆高速行驶。比如，可以设定第一预设速度为60km/h，当用户驾驶车辆的时速大于60km/h时，则认为用户在高速驾驶车辆行驶。或者，当前用户所用车辆性能比较好，可以将第一预设速度设置为65km/h；或者，当前使用车辆的用户为新手司机或该用户年龄较大，可以设置较低的第一预设速度，比如50km/h。当然，还可以根据其他情况设置第一预设速度，对此本申请实施例不做具体限定。
可选的，也可以通过车机的GPS确定出车机的实时位置，根据实时位置计算出车机的移动速度。而后，判断车机的移动速度是否大于第一预设速度。若车机的移动速度大于第一预设限速，可认为用户在驾驶车辆高速行驶。若车机的移动速度不大于第一预设速度，可认为用户不在驾驶车辆高速行驶。
可选的，在手机连接车机的情况下，车机也可以获取手机的数据，通过手机内设置的传感器(例如：加速度传感器)来获取手机的移动速度，从而确定用户是否在驾驶车辆高速行驶。
需要说明的是，在步骤S404的一种实现方式中，车机先对用户驾驶车辆是否处于预设场景进行判断。若处于预设场景则可直接执行步骤S405，即当车辆处于预设场景中时，用户要集中注意力于车辆驾驶，而不能过多的分散注意力操作车机。如果没有处于预设场景，则进一步的对当前车速是否大于第一预设速度即车辆是否处于高速驾驶状态进行判断。如果当前车速大于第一预设速度，则执行步骤S405，即使车辆没有处于预设场景，但当车辆处于高速驾驶状态的时候用户就要高度集中注意力于车辆驾驶。如果当前车速小于等于第一预设速度，则执行步骤S403，即只有当车辆未处于预设场景且当前车辆未处于高速驾驶状态的时候，车机才可以显示全部功能的用户界面以供用户使用。
在步骤S404的另一种实现方式中，车机先对当前车速是否大于第一预设速度进行判断。若当前车速大于第一预设速度，即当前车辆处于高速驾驶状态，则直接执行步骤S405，即当车辆处于高速驾驶状态的时候，用户必须高度集中注意力于车辆驾驶。若当前车速小于等于第一预设速度，则进一步对车辆是否处于预设场景进行判断。如上所述，如果处于预设场景，则执行步骤S405。如果没有处于预设场景，即当车辆未处于预设场景且当前车辆未处于高速驾驶状态，执行步骤S403。
S405、车机触摸屏显示第一用户界面。
具体的，第一用户界面不显示第一功能；或者，第一用户界面中以第一预设方式显示第一功能，第一预设方式用于指示第一功能无法被用户操作。并且，第一用户界 面中以第二预设方式显示第二功能，第二预设方式用于指示允许用户操作第二功能。其中，第一功能为操作时会占用用户较多视觉资源和认知资源的功能，第二功能为除第一功能以外的功能，第二功能占用用户的视觉资源或认知资源较少。此外，本申请实施例中的功能指的是某些功能或者某些功能的某些操作。该功能可以以电子设备上安装的APP的方式呈现，该操作可以是电子设备上安装的APP所能提供的操作选项。
其中，占用用户较多视觉资源和认知资源的功能指的是需要用户进一步思考并需要视觉参与后才可以进行的操作。比如：在拨号时，需要用户首先在脑海中回忆需要拨打的号码，并且需要利用视觉资源在触摸屏上按顺序点击相应的数字并确保点击正确，才能实现正确的拨号操作，这样就会占用用户大量的视觉资源和认知资源。又如：使用导航功能时，用户可能会进行地点搜索，此时，就必须利用视觉资源在触摸屏上输入地点，且要保证输入的正确性，有的时候导航功能会推荐几条路线，此时用户还需要进一步思考以确认最终的路线，这样就势必占用用户较多的视觉资源和认知资源。由于视觉资源和认知资源的占用会转移用户的大量注意力，使得用户不能集中注意力于驾驶车辆。因此，当车辆处于预设场景或者车速较快时，就必须集中注意力驾驶车辆才能保证行驶安全，车机需要将这些占用用户较多视觉资源和认知资源的第一功能隐藏或者使得用户无法操作第一功能，以保证行车安全。
那么，上述第一功能包括如下任意一项或几项：娱乐功能、信息功能、通话功能中的拨号功能、通话功能中的搜索联系人功能、导航功能中的搜索地址功能、音乐功能中的搜索歌曲功能、天气功能中的天气查询功能。第二功能包括如下任意一项或几项：通话功能的最近联系人功能、导航功能的推荐地址功能、音乐功能中的最近播放列表功能、天气功能中的本地实时天气功能。
需要说明的是，上述第一功能和第二功能仅仅是示例性的说明，第一功能和第二功能还可以包括其他功能。此外，上述第一功能和第二功能的划分，可以为厂商根据经验预配置的，也可以是车机根据用户的使用情况确定的，对此本申请实施例不做具体限定。
在一种可能的实现方式中，如图8所示，示例性的给出了两种第一用户界面。在用户选择主菜单601上的“主页”功能后显示界面602上对应的6个常用功能中，微信功能和娱乐功能使用时可能会占用用户较多的视觉资源或认知资源，比如，回复微信信息时，需要将视觉集中在触摸屏上，进行阅读或打字操作，进而无法关注前方驾驶情况，在预设场景中或者车速较快时会加大危险的发生比例。所以将微信功能和娱乐功能确定为第一功能，将地图功能，联系人功能，电话功能，天气功能确定为第二功能。因此，如图8中的(a)所示，第一用户界面不显示第一功能，只显示第二功能。即此时将第一功能隐藏，使得用户无法操作第一功能，但可以操作第二功能。或者，如图8中的(b)所示，在主屏幕上用画叉的方式使得第一功能无法被用户操作，但正常显示允许用户操作的第二功能。当然，除了画叉的方式之外，还可以采用图标变灰(点击后无法使用该功能)的方式使得第一功能无法被用户操作，本申请实施例对此不做具体限定。
在一种可能的实现方式中，如图9所示，示例性的又给出了一种第一用户界 面，该第一用户界面中的第一功能为通话功能的部分操作。在车机触摸屏上有些功能的部分操作会占用用户较多的视觉资源或认知资源，但此类功能又为用户常用或必须使用的功能，并不能采用上述方法将此类功能完全禁用(隐藏或不允许操作)。因此，可以将此类功能中占用用户较多的视觉资源或认知资源的操作禁用，以使用户集中注意力于车辆驾驶。比如，通话功能为一种必不可少的功能，为了避免错过重要联络讯息，车机不能直接完全的禁用该功能，但是为了保证用户行车安全，可以禁用该功能的部分操作。参见图9所示，相较于图7所示的通话界面，图9所示的通话界面中仅保留通话记录界面，而不显示拨号及联系人搜索功能，进而用户可以仅点击一次，就可以给最近通话的联系人回拨电话。实现通话联络而又不必占用较高的视觉资源或认知资源。又比如，导航功能为用户驾驶车辆的必备功能，也不能全面禁止使用该功能。因此，车机在导航界面仅提供地址推荐，用户通过点击相应的地址，获取一条最佳行驶路线，进而实现导航功能。禁止通过触摸屏搜索地址，从而保证用户的行车安全。
由此可见，本申请提供的显示用户界面方法，可以通过设置预设场景和第一预设速度，进而在车辆行驶过程中，车机可以判断当前车辆是否处于预设场景或当前车速是否大于第一预设速度，若确定车辆处于预设场景或当前车速大于第一预设速度，则车机确定显示第一用户界面，即在需要用户高度集中注意力于驾驶车辆的时候，车机可以通过不显示或者不允许用户操作占用用户较多视觉资源或认知资源的功能和/或操作的方式，保证用户行驶安全。以改善现有技术中，用户界面时刻显示全部功能，使得用户在需要高度集中注意力驾驶车辆时还需要分心操作占用视觉资源和认知资源较高的功能，而使得行驶不安全的情况。
在一种可能的实现方式中，车机在第一用户界面，可以为用户提供一个操作入口，以使用户可以通过其他占用用户视觉资源或认知资源较少的方式操作第一功能。比如，可以设置第一预设按钮为用户提供上述操作入口，并且利用第一预设按钮结合车机或者手机的语音功能引导用户进行相关的操作，以提高用户体验。示例性的，参见图10所示，在图8中的(b)显示的用户界面的基础上增加第一预设按钮。参见图11所示，在图9显示的用户界面的基础上增加第一预设按钮。第一预设按钮为用户提供了这类高资源占用型(占用用户较多视觉资源和认知资源)的功能或操作的入口，使得用户可以使用禁用的功能或操作。用户可以通过点击、拖动或者其他类型动作操作该第一操作预设按钮，当屏幕检测到用户对该第一操作预设按钮的相关操作时，表明用户想使用这类高资源占用型的功能或操作，此时，车机则会执行步骤S406，即可通过语音播报的形式引导用户操作这些功能。
需要说明的是，第一预设按钮可以由车机设置于第一用户界面，还可以设置显示于第二用户界面。以便车机触摸屏显示所有功能时也可以为用户提供其他占用用户视觉资源或认知资源较少的方式操作车机触摸屏。并且为了更加方便用户操作，第一预设按钮可以配置为悬浮按钮。对于第一预设按钮显示的用户界面及显示形态本申请实施例不做具体限定。
可选的，也可以不设置第一预设按钮，而是将以第一预设方式显示的第一功 能结合车机或者手机的语音功能引导用户进行相关的操作。即在第一用户界面检测到用户对第一功能图标的操作时就可以进入语音控制模式。由于第一用户界面可以为图8中的(a)所示的不显示第一功能的用户界面，或者为图8中的(b)所示的以第一预设方式显示第一功能并以第二预设方式显示第二功能的用户界面。此时，用户无法直接锁定第一功能或者需要在全部功能中挑选所需的第一功能，那么第一功能的选择会占用用户一定的注意力。因此，车机触摸屏可以在第一用户界面检测用户的第一操作，当检测到用户的第一操作后，如图12所示，车机触摸屏显示第三用户界面，该第三用户界面中通过第一预设方式显示全部的第一功能，并且在当前第三用户界面仅显示第一功能以便用户可以快速锁定需要的功能。其中，第一操作为用户在车机的触摸屏上的如下任一种的双击或滑动操作等：点击操作、滑动操作、预设按压手势操作、预设手势。其中，点击操作可以为用户在第一用户界面非功能图标显示区域处的单击，双击或多次连击操作。滑动操作为与现有车机触摸屏切换显示屏幕的方式区分的纵向或斜向滑动操作，或者为多指滑动操作等。预设按压手势操作为用户根据使用习惯设置的按压手势，比如，单指或多指按压等。预设手势操作为用户根据使用习惯设置的手势，比如，“画圆”等。本申请实施例对第一操作不做具体限定。
通过在车机触摸屏增加检测用户对第一预设按钮或第一功能图标的第二操作的检测，使得车机可以满足用户在当前车辆状态使用某些不允许使用的功能或操作的需求，在保证安全驾驶的前提下，提高了用户体验。
S406、进入语音控制模式。
具体的，当车机触摸屏检测到用户的第二操作后，车机启动语音交互功能。其中，第二操作为操作第一预设按钮或第一功能的图标，用于启动第一功能。语音控制模式用于用户与车机进行语音交互。车机根据语音交互功能提示用户可以通过第三操作操作第一功能，并告知用户第三操作的操作方法。其中，第三操作为语音交互形式的操作。
比如，用户操作图10所示的第一用户界面上的第一预设按钮或第一功能的图标后，进入语音控制模式，并显示图13或图15所示的用户界面。又如，用户操作如图12所示的第三用户界面上的第一功能图标后，进入语音控制模式，并显示图13或图15所示的用户界面。又如，用户操作图11所示的用户界面上的第一预设按钮后，进入语音控制模式，并显示图14所示的用户界面。
可选的，第一功能为某些功能时，参见图13所示，通过语音控制模式操作第一功能。用户在菜单栏601选择“主页”功能后，在显示界面602对应显示的用户界面上操作第一预设按钮进入语音控制模式，此时，车机会语音播报“当前操作存在风险”以提示用户这类功能会提高驾驶风险。车机继续语音播报“请问需要什么帮助”，以询问用户此时需要执行什么操作。用户可以回答想要执行的操作，比如参见图13所示，用户想要查看微信(信息)消息，就可以回答“查看最新微信消息”。由于车机可以不需要用户参与操作就可以将文字转化为语音进行播报，进而可以实现该操作，故判断当前用户想要使用的微信功能可以通过语音控制实现，即判断用户可以使用微信功能。因此车机可以语音播报“已打开微信”。 之后，播放用户要求查看的最新微信消息“妈妈消息“什么时候到家””。此时，用户可以直接通过语音控制车机执行想要进行的操控，比如利用车机进行信息回复，可以直接语音命令车机“回复“半小时””。最终车机接收到该命令，并语音播报回复内容“已回复“半小时””，使用户确认最终结果。如果不正确，则用户需要语音控制车机重新输入相关内容。比如，用户可以命令车机“当前消息错误”，“重新回复“半小时””，以便于车机执行正确操作。如果正确，则用户不必再进行操作。或者用户也可以通过在图10或图12所示的用户界面，操作第一功能的图标进而直接进入语音控制模式。通过上述操作，可使用户通过其他占用用户视觉资源或认知资源较少的方式操作第一功能，在保证用户行车安全的同时提高用户体验。
可选的，第一功能为某些功能的某些操作时，参见图14所示，通过语音控制模式操作第一功能。当用户在如图11所示的通话界面发现最近的通话记录中并没有想要联系的联系人，比如“妈妈”，也无法进行拨号操作，以至于无法拨打电话。那么用户就可以操作图11中的第一预设按钮，以出现图14所示的可以进行语音控制的用户界面。此时，车机会进行语音播报“请问需要什么帮助”。用户回答当前想要进行的操作，比如“打电话给妈妈”。车机对当前用户想要进行的操作进行判断是否可以通过语音操作完成。拨打电话这一操作，车机可以直接完成而不必用户手动控制。因此，车机可以进行拨号操作同时语音播报“正在拨打妈妈的住宅电话”，以告知用户当前所需操作正在执行。在保证行驶安全的同时满足客户需求。
可选的，当用户执行第二操作以启动语音控制模式操作第一功能时，车机会对该第一功能进行评估，以确认该第一功能是否可以通过语音控制模式进行操作。比如微信功能，可以利用文字和语音的转化而进行操作。再比如，某些娱乐功能，需要占用用户较高的视觉资源和认知资源，且无法通过语音进行操作，就会提示用户这类功能会提高驾驶风险而不能使用。
示例性的，参见图15所示，为不能通过语音控制模式操作第一功能的提示。一些功能无法利用语音进行简单的操控而实现目的，还需要用户进一步的思考才能实现最终功能，故，这部分功能应该完全禁止使用。比如，用户操作图10所示用户界面上的第一预设按钮或第一功能图标后，车机会语音播报“当前操作存在风险”以提示用户此时操作第一功能会提高驾驶风险。车机继续播报“请问需要什么帮助”。用户可以回答想要进行的操作，比如图10所示的娱乐功能，则用户可以语音命令车机“打开娱乐功能”。此时，车机需要判断当前用户命令启动的功能是否可以通过语音控制完成操作，由于娱乐功能需要用户手动参与而不能单纯的依靠语音操作，所以车机会判定当前状态无法使用该功能，进而语音播报“当前场景娱乐功能风险较大，无法运行”以阻止用户使用该功能，保证用户行车安全。
需要说明的是，当用户在语音控制模式下完成当前操作后，车机可以根据当前车辆所处场景，显示相应的用户界面。也可以当用户在语音控制模式下完成当前操作后，车机不必立即根据当前车辆所处场景切换用户界面，而是在预设时间 段内保留显示当前用户界面，进而使得用户可以继续利用语音控制模式操作当前功能，使得用户不必重新操作第一操作按钮进入当前功能。比如，参见图13、图14和图15中，当前用户界面中均包含有一“麦克风”图标，在预设时间段内，用户可以通过点击该图标继续使用当前功能进行相关的操作。比如，在图13的示例中，当用户确认当前车机回复的消息正确，但之后还想继续回复妈妈消息，则可以点击“麦克风”图标，再次命令车机回复相应的内容。或者，可以点击“麦克风”图标，命令车机“查看下一条新消息”或“回复同事A“明天我不上班””等。通过在语音控制模式的用户界面中加入该功能，可以减少用户的重复操作，提高效率，并且可以进一步的使用户将注意力集中于车辆驾驶。
可以理解的是，“麦克风”图标仅为示例性的表示，还可以利用其它图标或者其它形式使车机满足上述功能，本申请实施例对此不做具体限定。当然，也可以不设置上述图标用于实现继续使用语音控制模式，车机可以直接配置为在语音控制模式下，当用户当前语音操作完毕后，在预设时间段内保持均为语音控制模式，以便用户可以直接利用语音操作车机触摸屏上的功能。对此本申请实施例不做具体限定。
可选的，上述步骤S404中，当车机确定车辆处于预设场景时，参见图5所示，不必立即执行步骤S405，而是先执行步骤S407，判断当前车速是否大于第二预设速度，其中，第二预设速度为预设场景对应的最小限速。即可以通过执行步骤S407，使得当用户车辆处于预设场景而车速较低时，也可以使用车机触摸屏上的全部功能，为用户提供更好的体验。
S407、车机确定当前车速大于第二预设速度。若车机确定当前车速大于第二预设速度，则执行步骤S405。若车机确定当前车速小于等于第二预设速度，则执行步骤S403。
具体的，第二预设速度为预设场景对应限速中的最小限速，可以根据不同的预设场景分别对应设定不同的限速(第二预设速度)，将所有第二预设速度集合构成第二预设速度集。道路情况较为复杂时，用户可能同时处于几个预设场景中。比如车辆夜间行驶经过高危路段，此时，车机确定车辆处于两种预设场景“夜间行驶”和“高危路段”，则需要根据第二预设速度集获得当前两个场景对应的两个第二预设速度，进而获得其中较小的一个第二预设速度作为车机显示用户界面的判断依据。当用户驾驶车辆处在一个预设场景，则可以根据第二预设速度集获得当前场景对应的第二预设速度，并将该第二预设速度作为车机显示用户界面的判断依据。当用户驾驶车辆当前车速高于所处任意场景对应的第二预设速度时，就认为此时车速较高，需要高度集中注意力于驾驶车辆，即步骤S407判断为“是”。当然，也可以将预设场景对应的限速统一制定为某一第二预设速度，当用户当前车速高于第二预设速度时，即判定为“是”。上述第二预设速度集和第二预设速度为厂家根据车辆性能预设置的或者为车机根据用户操作习惯预配置的崔次本申请实施例不做具体限定。
示例性的，根据不同的预设场景分别设定不同的限速界限(第二预设速度)，构成第二预设速度集合。比如在人流密集路段行驶时，第二预设速度设置为30km/h；在夜间行驶时，第二预设速度设置为40km/h；在高危路段行驶时，第二预设速度设置为 15km/h；在恶劣天气行驶时，第二预设速度设置为20km/h；在限速为A路段行驶时，第二预设速度设置为50％*A，比如当前限速60km/h时，则设置第二预设速度为30km/h。那么，就可以得到第二预设速度集{30，40，15，20，50％*A}km/h。之后，车机根据当前用户所处的预设场景判断分别对应的第二预设速度，进而获得当前车辆所处场景对应的所有的第二预设速度中的最小第二预设速度。当前车速大于该最小第二预设速度，说明车辆当前处于需要高度集中注意力的场景，进而就需要用户将注意力集中在车辆驾驶上，因此，执行步骤S405，即车机显示隐藏或不允许用户操作第一功能的第一用户界面。
示例性的，因为在上述预设场景中，有些场景不好进行限速区分，或者说不同预设场景对应的第二预设速度相近。因此，可以为预设场景制定统一的第二预设速度。比如，预设场景中将第二预设速度统一设置为20km/h。此时，再根据用户驾驶车辆行驶的当前车速，判断当前车速是否大于第二预设速度，进而判定用户当前是否需要高度集中注意力，即使得车机显示的对应的用户界面。
在另一种可能的实现方式中，由于即使处于相同的预设场景，在不同的条件下也有可能制定出不同的第二预设速度。因此结合不同用户的不同条件或者车辆性能的不同状况条件，制定第二预设速度。
可选的，由于用户的驾驶熟练程度会影响用户对车机的操作使用。因此，可以根据用户驾车年限等影响用户驾车熟练程度的因素，设置相应场景的第二预设速度。例如对于新手司机来说，车速超过55km/h时就处于高速驾驶状态，而不能将过多的注意力用于操作车机；但是对于老司机而言，车速超过65km/h时不能将过多的注意力用于车机操作。即，可以根据用户驾驶年龄等因素判定用户驾车的熟练程度，进而针对不同场景设定不同的第二预设速度构成第二预设速度集。最终，可以由用户进行选择不同的第二预设速度集或者由厂家进行首次配置后续再根据年检进行更改。当然，也可以由车机根据用户的操作进而为用户配置对应的模式。其中，不同的配置模式即为针对不同的驾驶熟练程度配置的不同第二预设速度集合。例如：可以根据用户的驾驶熟练程度将用户分为三个级别：A级，B级和C级。那么可以认为A级的用户驾车最为熟练，可以将A级用户在不同预设场景对应的第二预设速度设置为较高的速度；B级用户的驾驶熟练程度为一般级别，可以将B级用户在不同预设场景对应的第二预设速度设置为中等水平，并且可以将B级用户对应的第二速度集合作为默认第二预设速度集合使得无法确定用户驾驶熟练程度的车辆均配置B级第二预设速度集合。C级用户则可以使用针对新手司机设置的第二预设速度集合。
可选的，用户的健康状况或是年龄等情况也会对驾驶安全产生一定的影响。因此，可以根据用户年龄等影响用户驾车状态的因素，设置相应场景的第二预设速度。例如，用户患有心脏病，不能更好的应对突发状况，那么就需要将该用户的第二预设速度集合设置的较低，以保证用户驾驶安全。或者，用户年龄比较大，也会使得其反应速度较慢，进而也需要将其的第二预设速度集合制定的较低。当然，也可以利用车辆内部或者手机的摄像头捕捉用户面部表情，进而采用图像分析技术，分析用户当前状态是否异常，如果用户状态不佳，车机就可以制定较低的第二预设速度集合，以保证用户可以应对预设场景中的情况，保证用户行驶安全。
可选的，车辆的性能对于突发状况的处理能力也会不同。因此，可以根据不同的车辆性能设置不同预设场景对应的第二预设速度集合。例如性能较差的车辆，其制动功能可能也会较差，进而面对突发情况时无法及时刹车保证用户安全。因此，也需要制定较低的第二预设速度集合，使得用户在较低的车速时才可以触摸操作车机触摸屏的全部功能，进而保证用户的注意力足够应对突发状况。
当然，除上述列举的几种情况，也会有其他用户及车辆的条件对不同预设场景第二预设速度的设置产生影响，对此本申请实施例不做具体限定。
在一种可能的实现方式中，还可以设置第一时间阈值。比如当用户界面为第一用户界面时，可能下一时刻用户所处场景满足车机触摸屏显示包含所有功能的用户界面的条件，那么也不必立即进行界面切换。而需要在当前状态保持时间超过第一时间阈值后再进行用户界面切换。因为车辆在道路上行驶情况较为复杂，有可能出现突发状况临时使得车速降低，此时，需要用户将更多的注意力用于观察路况进行分析，而不能将视觉资源和认知资源过多的用于用户界面操作，因此设置第一时间阈值可以进一步的保证用户的行车安全。
在一种可能的实现方式中，当用户在显示第二用户界面的触摸屏上操作未完成，而用户所处场景切换为需要车机显示第一用户界面时，需要立即中断用户当前操作，进行用户界面切换，以保证用户行车安全。或者，也可以在用户完成当前操作后再进行用户界面切换操作，但同时也应语音播报提示用户当前场景存在驾驶风险，在满足用户需求的同时保证用户行车安全。
由此可见，本申请提供的显示用户界面方法，可以在设置预设场景和第一预设速度的基础上再设置第二预设速度，进而可以根据车辆所处的场景和行驶的实时速度判定应该显示的用户界面，在需要用户高度集中注意力的时候，车机可以显示第一用户界面，进而保证用户行驶安全。并且，还可以通过检测用户第二操作功能的设置，使得用户可以在第一用户界面获得其他不必占用用户视觉资源或认知资源的方式操作第一功能，提高用户体验。以改善现有技术中，用户界面时刻显示全部功能，使得用户在需要高度集中注意力驾驶车辆时还需要分心操作占用视觉资源和认知资源较高的功能，而使得行驶不安全的情况。
