由上述方法可知,中控设备可以根据驾驶信息的变化调整中控屏上应用的显示方式,避免驾驶员的注意力被过多的分散在中控设备的应用上,从而实现提高驾驶安全。
结合第一方面,在一些实施例中,第一驾驶信息是朝第一方向变化为第二驾驶信息,第一方向用于指示车辆驾驶的注意力需求增加的方向。
结合第一方面,在一些实施例中,第一方向包括以下一项或多项:车速增大的方向、自动驾驶模式的层级下降的方向、道路的拥堵程度增加的方向、路上行人的数量增加的方向、路上车辆的数量增加的方向、道路的曲直程度增加的方向。
结合第一方面,在一些实施例中,在第一驾驶信息朝第一方向变化为第二驾驶信息的情况下,第一显示方式和第二显示方式的区别包括:中控设备按照第二显示方式显示的应用图标的数量少于按照第一显示方式显示的应用图标的数量,和/或,中控设备按照第二显示方式在第一区域显示的应用图标对应的应用对注意力的分散程度小于按照第一显示方式在第一区域显示的应用图标对应的应用对注意力的分散程度,第一区域为中控设备的屏幕上靠近驾驶位置的区域。

结合第一方面,在一些实施例中,第五应用的功能包括第二功能,中控设备获取车辆在第二时间段内的第二驾驶信息之后,中控设备接收到调用第二功能的第二操作;响应于第二操作,中控设备可以根据第二驾驶信息拒绝启动第二功能。
由上述实施例可知,中控设备在接收到调用应用中的一项功能的操作时,还可以根据当前的驾驶信息确定是否启动这一项功能。其中,若上述操作要调用的功能在启动后会过度分散注意力,导致驾驶员难以投入足够的注意力在车辆驾驶上的情况下,中控设备可以拒绝启动该功能。这可以避免车辆驾驶过程中,驾驶员启动在运行阶段分散注意力程度较高的功能,从而使得驾驶员能有足够的注意力投入车辆驾驶,提高驾驶安全。
结合第一方面,在一些实施例中,中控设备可以获取车辆在第三时间段内的第三驾驶信息,并根据第三驾驶信息确定第五显示方式,第三时间段是第二时间段之后的一段时间,第五显示方式与第二显示方式不同,第二驾驶信息是朝第二方向变化为第三驾驶信息,第二方向用于指示车辆驾驶的注意力需求减少的方向。中控设备可以按照第五显示方式显示中控设备中的应用。
结合第一方面,在一些实施例中,第二方向包括以下一项或多项:车速减小的方向、自动驾驶模式的层级上升的方向、道路的拥堵程度降低的方向、路上行人的数量减少的方向、路上车辆的数量减少的方向、道路的曲直程度减小的方向。
结合第一方面,在一些实施例中,第五显示方式和第二显示方式的区别包括:中控设备按照第五显示方式显示的应用图标的数量多于按照第二显示方式显示的应用图标的数量,和/或,中控设备按照第二显示方式在第一区域显示的应用图标对应的应用对注意力的分散程度小于按照第五显示方式在第一区域显示的应用图标对应的应用对注意力的分散程度,第一区域为中控设备的屏幕上靠近驾驶位置的区域。
由上述实施例可知,在驾驶信息变化,驾驶员可以在车辆驾驶上投入更少的注意力的情况下,中控设备可以恢复显示一个或多个之前隐藏的应用图标。也即是说,中控屏上应用的显示方式可以根据驾驶信息的变化而动态调整。若在当前驾驶信息下,驾驶员需要在车辆驾驶上投入更多的注意力,中控屏上应用的显示方式可以减少驾驶员在驾驶过程中操作容易分散注意力的应用的机会。若在当前驾驶信息下,驾驶员可以在车辆驾驶上投入更少的注意力,中控屏上应用的显示方式可以增加更多对注意力的分散程度更多的应用图标,从而驾驶员能够使用的应用更多。上述方法不仅可以减少驾驶员的注意力被中控设备上的应用过度分散的情况,而且可以减少驾驶员使用中控设备中的应用的影响。
结合第一方面,在一些实施例中,第三应用在中控设备获取到第二驾驶信息之后被停止运行,中控设备获取车辆在第三时间段内的第三驾驶信息之后,中控设备可以恢复运行第三应用。
由上述实施例可知,在驾驶信息变化,驾驶员可以在车辆驾驶上投入更少的注意力的情况下,中控设备可以恢复运行之前停止运行的应用。
例如,中控设备根据第二驾驶信息停止运行音乐应用。那么,音乐应用中正在播放的音乐暂停播放。当获取到第三驾驶信息,中控设备可以根据第三驾驶信息恢复运行上述音乐应用。那么,音乐应用中播放的音乐可以从上一次暂停的位置处开始播放。
结合第一方面,在一些实施例中,中控设备根据第二驾驶信息确定第二显示方式之前,中控设备还可 以检测到车辆的副驾驶位置存在用户。中控设备可以获取车辆在第四时间段内的第四驾驶信息,且检测到在第四时间段内车辆的副驾驶位置不存在用户,第四时间段是第二时间段之后的一段时间,第四驾驶信息与第二驾驶信息相同。中控设备可以根据第四驾驶信息确定第六显示方式,并按照第六显示方式显示中控设备中的应用。
其中,第六显示方式和第二显示方式的区别包括:中控设备按照第六显示方式显示的应用图标的数量少于按照第二显示方式显示的应用图标的数量,和/或,中控设备按照第六显示方式在第一区域显示的应用图标对应的应用对注意力的分散程度小于按照第二显示方式在第一区域显示的应用图标对应的应用对注意力的分散程度,第一区域为中控设备的屏幕上靠近驾驶位置的区域。
由上述实施例可知,当驾驶信息相同时,在车内前排仅有驾驶员的情况下中控设备显示应用的显示方式与在车内前排同时有驾驶员和副驾驶员的情况下中控设备显示应用的显示方式不同。可以理解的,车辆驾驶可以无需副驾驶员投入注意力。中控设备在车内前排同时有驾驶员和副驾驶员的情况下隐藏的应用数量,可以比车辆在相同行驶状态下但车内前排仅有驾驶员的情况下更少。这可以减少根据驾驶信息调整应用的显示方式对副驾驶员使用中控设备中的应用的影响。
结合第一方面,在一些实施例中,中控设备根据第一驾驶信息确定第一显示方式的具体方法可以为:中控设备可以根据第一驾驶信息确定注意力要求等级ARL为第一ARL,并获取中控设备中应用的注意力分散等级ADL。中控设备根据第一ARL、中控设备中应用的ADL,确定第一显示方式。其中,第一显示方式包括,隐藏应用的ADL高于第一ARL对应的第一ADL阈值的应用的图标,和/或,将应用的ADL小于等于第一ADL阈值的应用的图标显示在第一区域,第一区域为中控设备的屏幕上靠近驾驶位置的区域。
中控设备根据第二驾驶信息确定第二显示方式的具体方法可以为:中控设备可以根据第二驾驶信息确定注意力要求等级ARL为第二ARL。中控设备根据第二ARL、中控设备中应用的ADL,确定第二显示方式。其中,第二显示方式包括,隐藏应用的ADL高于第二ARL对应的第二ADL阈值的应用的图标,和/或,将应用的ADL小于等于第二ADL阈值的应用的图标显示在第一区域。
结合第一方面,在一些实施例中,第二ARL大于第一ARL,第二ARL对应的第二ADL阈值小于第一ARL对应的第一ADL阈值。
上述ARL越大,可以表示驾驶员需要在车辆驾驶上投入的注意力越多。第二ARL大于第一ARL,可以表示第一驾驶信息朝上述第一方向(即车辆驾驶的注意力需求增加的方向)变化为上述第二驾驶信息。
ARL越大,ARL对应的ADL阈值可以越大。这样,当ARL增大,中控设备可以隐藏更多ADL更小的应用,从而减少中控设备中的应用对注意力的分散程度,使得驾驶员能在车辆驾驶上投入足够的注意力。
结合第一方面,在一些实施例中,上述应用的ADL为应用在启动阶段的ADL。中控设备根据应用启动信息评估应用在启动阶段的ADL,应用启动信息包括:应用启动时的操作复杂度和应用类别,其中,应用启动时的操作复杂度越大,应用在启动阶段的ADL越大;在应用启动时的操作复杂度相同的情况下,应用类别为驾驶辅助类的应用在启动阶段的ADL小于应用类别为非驾驶辅助类的应用在启动阶段的ADL。
结合第一方面,在一些实施例中,中控设备根据第一驾驶信息确定注意力要求等级ARL为第一ARL之后,中控设备可以获取中控设备中正在运行的应用在运行阶段的ADL。中控设备隐藏应用在运行阶段的ADL高于第一ADL阈值的应用。中控设备根据第二驾驶信息确定注意力要求等级ARL为第二ARL之后,中控设备可以获取中控设备中正在运行的应用在运行阶段的ADL。中控设备隐藏应用在运行阶段的ADL高于第二ADL阈值的应用。
结合第一方面,在一些实施例中,中控设备可以根据应用运行信息评估应用在运行阶段的ADL,应用运行信息包括:应用在运行阶段需要用户操作时的操作复杂度、应用在运行阶段不需要用户操作时视觉吸引的时长或非视觉吸引的时长、应用类别,其中,应用在运行阶段需要用户操作时的操作复杂度越大,应用在运行阶段的ADL越大;应用在运行阶段不需要用户操作时视觉吸引的时长或非视觉吸引的时长越长,应用在运行阶段的ADL越大;当应用在运行阶段需要用户操作时的操作复杂度相同,或者应用在运行阶段不需要用户操作时视觉吸引的时长相同或非视觉吸引的时长相同,应用类别为驾驶辅助类的应用在运行阶段的ADL小于应用类别为非驾驶辅助类的应用在运行阶段的ADL。
结合第一方面,在一些实施例中,中控设备可以获取车辆在第三时间段内的第三驾驶信息,并根据第三驾驶信息确定第三ARL。上述第三时间段可以是第二时间段之后的一段时间。第三ARL小于上述第二ARL。中控设备可以根据第三ARL,隐藏在启动阶段的ADL高于第三ARL对应的第三ADL阈值的应用 的应用图标,并显示在启动阶段的ADL小于等于上述第三ADL阈值的应用的应用图标。也即是说,中控设备可以恢复显示根据第二驾驶信息隐藏的应用图标。上述被恢复显示的应用图标对应的应用,即为在启动阶段的ADL高于第二ARL对应的第二ADL阈值,且小于等于第三ARL对应的第三ADL阈值的应用。
可选的,中控设备还可以根据第三ARL,停止运行在运行阶段的ADL高于上述第三ADL阈值的应用,并保持在运行阶段的ADL小于等于上述第三ADL阈值的应用。其中,中控设备还可以恢复运行根据第二驾驶信息而停止运行的应用。上述被恢复运行的应用,即为在运行阶段的ADL高于第二ADL阈值,且小于等于第三ADL阈值的应用。
结合第一方面,在一些实施例中,中控设备中可存储有驾驶信息与显示方式的对应关系。当获取到第一驾驶信息,中控设备可以查询第一驾驶信息对应的应用的显示方式为第一显示方式。可选的,当获取到第一驾驶信息,中控设备还可以查看到第一驾驶信息对应的一个应用的用户界面的显示方式。
由上述实施例可知,中控设备可以根据驾驶信息和显示方式的对应关系确定中控屏上当前对应用的显示方式或者应用的用户界面的显示方式。这样,中控设备可以不用先根据驾驶信息评估ARL,然后再根据ARL和ADL确定显示方式。上述实施例可以提高中控设备对调整显示方式的效率,更迅速地根据驾驶信息的变化调整中控设备中应用对驾驶员注意力的吸引,从而提高驾驶安全。
第二方面,本申请提供一种电子设备,该电子设备可包括屏幕、存储器、一个或多个处理器,其中,该屏幕可用于显示应用图标、应用的用户界面,该存储器可用于存储计算机程序,该一个或多个处理器可用于调用该计算机程序,使得该电子设备执行如第一方面中任一可能的实现方法。

具体实施方式
下面结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。其中,在本申请实施例的描述中,以下实施例中所使用的术语只是为了描述特定实施例的目的,而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样,单数表达形式“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式,除非其上下文中明确地有相反指示。还应当理解,在本申请以下各实施例中,“至少一个”、“一个或多个”是指一个或两个以上(包含两个)。术语“和/或”,用于描述关联对象的关联关系,表示可以存在三种关系;例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B的情况,其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中 包括结合该实施例描述的特定特征、结构或特点。由此,在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例,而是意味着“一个或多个但不是所有的实施例”,除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”,除非是以其他方式另外特别强调。术语“连接”包括直接连接和间接连接,除非另外说明。“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请以下实施例中的术语“用户界面(user interface,UI)”,是应用程序(application,APP)或操作系统(operating system,OS)与用户之间进行交互和信息交换的介质接口,它实现信息的内部形式与用户可以接受形式之间的转换。用户界面是通过java、可扩展标记语言(extensible markup language,XML)等特定计算机语言编写的源代码,界面源代码在电子设备上经过解析,渲染,最终呈现为用户可以识别的内容。用户界面常用的表现形式是图形用户界面(graphic user interface,GUI),是指采用图形方式显示的与计算机操作相关的用户界面。它可以是在电子设备的显示屏中显示的文本、图标、按钮、菜单、选项卡、文本框、对话框、状态栏、导航栏、Widget等可视的界面元素。
在一些实施例中,车辆可以通过驾驶辅助技术,降低因驾驶员犯错而导致交通事故的概率。例如,车辆上可安装有自动紧急制动装置。在车辆遇到突发危险情况或与前车及行人距离小于安全距离时,车辆可以通过自动紧急制动装置主动刹车。再例如,车辆上可配置有车道辅助系统,可以确保车辆在车道内行驶,避免出现车辆在行驶中占据多条车道或者脱离行驶路线突然驶向其它车道。再例如,车辆上可配置有驾驶员监控系统。当监测到驾驶员的实现从前方道路上移开时间过程,车辆可以进行提示或告警以提示用户提高驾驶的注意力。
上述方法可以在一定程度上降低由于驾驶员注意力被分散(例如被中控设备上的应用分散)而出现驾驶事故的概率。但是,上述方法难以避免中控设备上的应用对驾驶员注意力分散的影响。在需要驾驶员高度集中注意力开车时,中控设备上的应用分散驾驶员的注意力容易导致驾驶事故。
本申请提供一种车辆中控设备的应用控制方法,该方法可以根据驾驶过程中对驾驶员注意力的要求,调整中控设备上的应用对驾驶员注意力分散的影响程度,从而使得驾驶员能将足够的注意力放在车辆驾驶上,以应对当前的驾驶路况,提高驾驶安全。
具体的,中控设备可以根据驾驶信息进行注意力要求等级(attention requirement level,ARL)评估。上述ARL可以表示车辆驾驶对驾驶员注意力要求的高低。ARL越高,车辆驾驶对驾驶员注意力的要求越高。上述驾驶信息可包括车辆行驶状态、路况(如道路的曲直程度、路上行人的数量、路上车辆的数量、道路的拥堵程度)等等。中控设备还可以评估中控设备上的应用在启动阶段和运行阶段的注意力分散等级(attention distraction level,ADL)。上述应用在启动阶段的ADL可以表示启动该应用对驾驶员的注意力分散的多少。上述应用在运行阶段的ADL可以表示该应用在运行过程中对驾驶员的注意力分散的多少。ADL越高,应用对驾驶员的注意力分散得越多。中控设备可以根据ARL、应用在启动阶段的ADL以及预设的应用隐藏策略将中控屏上显示的部分应用图标隐藏,从而避免驾驶员因手动启动上述应用图标被隐藏的应用而分散注意力。中控设备可以根据ARL、应用在运行阶段的ADL以及预设的应用隐藏策略将中控设备中正在运行的部分应用关闭,从而避免上述被关闭的应用的运行分散驾驶员的注意力。上述应用隐藏策略可用于指示在不同的ARL下,需要隐藏的应用的ADL的大小。
由上述方法可知,中控设备可以根据驾驶信息的变化调整中控屏上显示的应用图标的数量以及中控设备中运行的应用的数量。其中,中控设备可以根据驾驶过程中对驾驶员注意力要求的高低,隐藏对注意力分散过多,会干扰当前驾驶的应用。其中,中控设备隐藏应用可包括隐藏中控屏上显示的应用图标和/或拒绝运行应用。上述方法可以减少驾驶员在驾驶过程中对容易分散注意力的应用进行操作的情况,从而避免驾驶员的注意力被过多分散在中控设备的应用上,提高驾驶安全。
在一些实施例中,中控设备中可存储有应用控制表。上述应用控制表可用于指示不同的驾驶信息与需要隐藏的应用之间的关系。中控设备可以根据当前获取的驾驶信息以及上述应用控制表来判断哪些应用为当前需要隐藏的应用。那么,当驾驶信息变化,中控设备可以调整中控设备中被隐藏的应用。
在一种可能的实现方式中,当根据当前获取的驾驶信息以及上述应用控制表确定出需要隐藏的应用, 中控设备可以在中控屏上隐藏上述需要隐藏的应用的图标,以及停止运行上述需要隐藏的应用中正在运行的应用。
在另一种可能的实现方式中,上述应用控制表中可具体包含不同的驾驶信息对应的需要隐藏的应用,以及对应用进行隐藏的方式。上述对应用进行隐藏的方式可包括:在中控屏上隐藏引用的图标、拒绝运行应用。当根据当前获取的驾驶信息以及上述应用控制表确定出需要隐藏的应用,中控设备可以根据应用控制表中相应的应用隐藏方式对上述需要隐藏的应用进行隐藏。
不限于应用控制表,驾驶信息与待隐藏应用之间的关系还可以通过其它的方式存储在中控设备中。
例如,上述驾驶信息可包括车速。在上述应用控制表中,车速越快,则需要隐藏的应用越多。应用控制表可包含在不同的车速下,需要隐藏的应用的标识。若车速为v1时需要隐藏的应用包括应用a1~应用an,则中控设备在检测到当前车速为v1时,隐藏上述应用a1~应用an。上述隐藏应用a1~应用an可包括在中控屏上隐藏应用a1~应用an的图标,以及停止运行应用1~应用an中正在运行的应用。可选的,应用控制表中还包括在不同的驾驶信息下,对应用进行隐藏的方式。中控设备可以根据应用控制表确定在车数v1时,对上述应用a1~应用an进行隐藏的方式。例如,对应用a1~应用an进行隐藏的方式包括:在中控屏上隐藏应用a1~应用an中部分应用(如应用a1~应用aq)的图标,以及停止运行应用a1~应用an中的部分应用(如应用a1~应用am)。则中控设备可以根据上述隐藏方式在中控屏上隐藏应用a1~应用aq的图标,以及停止运行应用a1~应用am中正在运行的应用。可以理解的,中控设备可以显示在车速v1下应用控制表未声明需要隐藏的应用(即上述应用a1~应用an以外的其它应用)的图标,并且可以运行上述未声明需要隐藏的应用。
再例如,上述驾驶信息可包括自动驾驶模式的层级。在上述应用控制表中,自动驾驶模式的层级越高,则需要隐藏的应用越少。应用控制表可包含在不同的自动驾驶模式的层级下,需要隐藏的应用的标识。若自动驾驶模式的层级为L3时需要隐藏的应用包括应用b1~应用bn,则中控设备在检测到自动驾驶模式的层级为L3时,隐藏上述应用b1~应用bn。中控设备隐藏应用的方法可以参考前述实施例的介绍。可以理解的,上述应用b1~应用bn之外的其它应用可以不被隐藏。
再例如,上述驾驶信息可包括道路的拥堵程度。在上述应用控制表中,道路的拥堵程度越高,则需要隐藏的应用越多。应用控制表可包含在不同的道路的拥堵程度下,需要隐藏的应用的标识。其中,道路的拥堵程度可包括不同的等级:通畅、比较拥堵和特别拥堵。本申请对道路的拥堵程度的等级划分方式不作限定。若道路特别拥堵时需要隐藏的应用包括应用c1~应用cn,则中控设备在检测到道路特别拥堵时,隐藏上述应用c1~应用cn。中控设备隐藏应用的方法可以参考前述实施例的介绍。可以理解的,上述应用c1~应用cn之外的其它应用可以不被隐藏。
驾驶信息还可以包括更多的内容,本申请实施例对此不作限定。
其中,上述应用控制表中可包含单项驾驶信息在不同取值下与需要隐藏的应用之间的关系,还可以包含在多项驾驶信息结合的情况下,这多项驾驶信息在不同的取值下与需要隐藏的应用之间的关系。例如,上述应用控制表中可包含在不同的车速下,需要隐藏的应用的标识。上述隐藏应用表中还可以包含车速在指定车速,且自动驾驶模式的层级在指定层级的情况下,需要隐藏的应用的标识。
由上述实施例可知,中控设备可以根据驾驶信息和应用控制表快速确定需要隐藏的应用。这样,中控设备可以不用先根据驾驶信息评估ARL,然后再根据ARL和ADL确定需要隐藏的应用。上述实施例可以提高中控设备对应用进行隐藏的效率,更迅速地根据驾驶信息的变化调整中控设备中应用对驾驶员注意力的吸引,从而提高驾驶安全。
在一些实施例中,中控设备可以更新上述应用控制表。例如,当中控设备安装了新的应用,中控设备可以将应用的标识添加至应用控制表中。这样,中控设备可以在车辆运行过程中判断是否隐藏该应用。在一种可能的实现方式中,中控设备可以从云服务器中获取上述应用控制表。云服务器中可存储有应用市场中所有应用需要隐藏时对应的驾驶信息取值。当中控设备安装了新的应用,中控设备可以从云服务器获取该应用需要隐藏时对应的驾驶信息取值,从而更新应用控制表。在另一种可能的实现方式中,中控设备可以根据应用的ADL来得到上述应用控制表。当中控设备安装了新的应用,中控设备可以确定应用的ADL。然后,中控设备可以根据应用的ADL确定应用需要隐藏时对应的驾驶信息取值,从而更新应用控制表。
下面介绍本申请实施例提供的一种评估ARL的实现方法。
根据车辆运行状态、驾驶模式以及路况等因素的不同,车辆在行驶过程中对驾驶员注意力的要求是不同的。
例如,车辆在停止的情况下,对驾驶员注意力的要求接近于0。即驾驶员在车辆停止时可以无需将注 意力放在车辆驾驶上。
再例如,在车辆行驶过程中,车速越快,对驾驶员注意力的要求越高。车辆行驶过程中的路况越复杂(如行驶道路曲折、路上车辆和行人多),对驾驶员注意力的要求越高。
再例如,车辆在自动驾驶模式下,自动驾驶模式的层级越高,需要用户手动操作来进行车辆驾驶的情况越少。那么,自动驾驶模式的层级越高,对驾驶员注意力的要求越低。
在一种可能的实现方式中,中控设备可以采集车辆的驾驶信息,并根据驾驶信息评估车辆行驶的ARL。上述驾驶信息可包括车辆行驶状态、路况。车辆行驶状态可包括车速、是否开启自动驾驶模式、自动驾驶模式的层级。路况可包括道路的曲直程度、路上行人的数量、路上车辆的数量、道路的拥堵程度。
其中,根据车辆行驶过程中对驾驶员注意力要求的不同,ARL可以划分为六个等级:ARL0、ARL1、ARL2、ARL3、ARL4、ARL5。
ARL0可以表示车辆行驶可以无需驾驶员在驾驶上投入注意力。在ARL为ARL0的情况下,驾驶员通常不需要进行任何驾驶操作。
ARL1可以表示车辆行驶至少需要驾驶员在驾驶上投入少量注意力。在ARL为ARL1的情况下,驾驶员通常只需要进行少量驾驶操作,驾驶员可以绝大部分注意力不在驾驶上。例如,在自动驾驶模式下,驾驶员可以只需要在系统请求时进行应答或者接管驾驶。
ARL2可以表示车辆行驶至少需要驾驶员在驾驶上投入主要注意力。例如,在自动驾驶模式下,若驾驶员要随时准备主动接管驾驶,则中控设备可以评估确定ARL为ARL2。
ARL3可以表示车辆行驶需要驾驶员在驾驶上投入大部分注意力。
ARL4可以表示车辆行驶需要驾驶员在驾驶上投入绝大部分注意力,以保证能及时应对车辆行驶过程中的各种情况(例如遇到红灯或前方有行人时及时停车、变道时注意后方来车等)。在ARL为ARL4的情况下,车辆行驶过程中的绝大部分驾驶操作均需要驾驶员手动完成。
ARL5可以表示车辆行驶需要驾驶员全神贯注,将所有注意力都集中在车辆驾驶上,以保证能迅速应对车辆行驶过程中的各种情况。
需要进行说明的是,ARL划分为上述六个等级ARL0~ARL5仅为示例性说明,不应对本申请构成限定。根据车辆行驶过程中对驾驶员注意力要求的不同,ARL还可以划分为更多或更少的等级。
中控设备可以根据当前采集到的驾驶信息来评估当前的ARL为哪一个等级。
下面以ARL包括六个等级ARL0~ARL5为例说明中控设备评估ARL的不同情况。
(1)当检测到车辆停止(即车速为0),中控设备可以确定当前的ARL为ARL0。
(2)在车辆处于手动驾驶模式下,当检测到车辆低速行驶并且路况简单,中控设备可以确定当前的ARL为ARL3。
(3)在车辆处于手动驾驶模式下,当检测到车辆中速行驶或者路况较为复杂,中控设备可以确定当前的ARL为ARL4。
(4)在车辆处于手动驾驶模式下,当检测到车辆高速行驶或者路况复杂,中控设备可以确定当前的ARL为ARL5。
其中,车辆低速行驶可以例如是车辆的行驶速度小于40千米/小时。车辆中速行驶可以例如是车辆的行驶速度大于或等于40千米/小时,且小于或等于60千米/小时。车辆高速行驶可以例如是车辆的行驶速度大于60千米/小时。上述根据行驶速度对车辆低速行驶、中速行驶和高速行驶的划分仅为示例性说明,不应对本申请构成限定。中控设备还可以根据其它的划分方式来划分低速行驶、中速行驶和高速行驶。
中控设备可以根据车辆行驶道路的曲直程度、路上行人的数量、路上车辆的数量等来判断路况是简单,还是较为复杂,还是复杂。例如,当检测出道路的曲直程度在第一曲直区间、路上行人的数量在第一行人数量区间且路上车辆的数量在第一车辆数量区间,中控设备可以确定路况简单。当检测出道路的曲直程度在第二曲直区间、或路上行人的数量在第二行人数量区间、或路上车辆的数量在第二车辆数量区间,中控设备可以确定路况较为复杂。当检测出道路的曲直程度在第三曲直区间、或路上行人的数量在第三行人数量区间、或路上车辆的数量在第三车辆数量区间,中控设备可以确定路况复杂。上述第一曲直区间内的值小于第二曲直区间的值。第二曲直区间的值小于第三区间的值。上述第一行人数量区间的值小于第二行人数量区间的值。上述第二行人数量区间的值小于第三行人数量区间的值。上述第一车辆数量区间的值小于第二车辆数量区间的值。第二车辆数量区间的值小于第三车辆数量区间的值。上述中控设备判断路况是简单,还是较为复杂,还是复杂的方式仅为示例性说明,不应对本申请构成限定。
(5)在车辆处于自动驾驶模式下,当检测自动驾驶模式的层级为L0~L2,中控设备评估ARL的策略 可以与车辆处于手动驾驶模式时评估ARL的策略相同。
(6)在车辆处于自动驾驶模式下,当检测到自动驾驶模式的层级为L3,中控设备可以确定当前的ARL为ARL2。
(7)在车辆处于自动驾驶模式下,当检测到自动驾驶模式的层级为L4,中控设备可以确定当前的ARL为ARL1。
(8)在车辆处于自动驾驶模式下,当检测到自动驾驶模式的层级为L5,中控设备可以确定当前的ARL为ARL0。
其中,自动驾驶模式的层级按照从低到高的顺序可以划分为L0~L5。上述自动驾驶模式的层级仅为示例性说明,不应对本申请构成限定。可以理解的,自动驾驶模式还可以包含更多或更少的层级。
上述评估车辆在不同行驶情况下的ARL的具体大小仅为本申请示例性说明,不应对本申请构成限定。不限于使用车辆行驶状态、路况,采用其它的驾驶信息对车辆行驶过程中ARL的方法,只要基于本申请提供的同一发明思想,都在本申请保护范围内。
下面介绍本申请实施例提供的一种评估应用的ADL的实现方法。
中控设备可包含三种类别的应用:驾驶辅助类应用、车辆控制类应用和生活娱乐类应用。不同的应用对驾驶员注意力的分散程度不同。即不同的应用的ADL可以不同。
其中,驾驶辅助类应用可用于辅助驾驶员驾驶。驾驶辅助类应用对驾驶员注意力的分散程度较小。
车辆控制类应用一般在操作期间吸引驾驶员的注意力,对驾驶员注意力的分散程度取决于操作难易程度和操作时长。其中,使用车辆控制类应用控制车辆的操作越难,该车辆控制类应用对驾驶员注意力的分散程度越大。使用车辆控制类应用控制车辆的操作时间越长,该车辆控制类应用对驾驶员注意力的分散程度越大。
生活娱乐类应用在启动后,对驾驶员的注意力吸引一般是持续性的。生活娱乐类应用对驾驶员注意力的分散程度通常是上述三种类别的应用中最大的。
另外,应用的ADL可包括应用在启动阶段的ADL、应用在运行阶段的ADL。可以理解的,一个应用在启动阶段和运行阶段对驾驶员注意力的分散程度也可以不同。例如,驾驶员可以通过语音指令启动中控设备中的视频应用,而无需驾驶员手动操作中控屏以及眼睛盯着中控屏,则该视频应用在启动阶段的ADL比较小。视频应用在运行阶段会对驾驶员产生持续性地视觉吸引,较多地分散驾驶员的注意力,则该视频应用在运行阶段的ADL比较大。
在一种可能的实现方式中,中控设备可以根据应用在启动阶段的操作复杂度、应用类别来评估应用在启动阶段的ADL。中控设备可以根据应用在运行阶段是否需要用户操作、操作复杂度、对驾驶员的注意力吸引程度、应用类别来评估应用在运行阶段的ADL。
其中,根据应用对驾驶员注意力分散程度的不同,ADL可以划分为六个等级:ADL0、ADL1、ADL2、ADL3、ADL4、ADL5。
ADL0可以表示应用几乎不吸引驾驶员的注意力,或者使用应用进行的操作本身属于驾驶需要。在一个应用启动阶段或运行阶段的ADL为ADL0的情况下,这一个应用启动或运行通常不会干扰驾驶员驾驶。这样驾驶员能将足够的注意力投入车辆驾驶,从而迅速处理突发状况,减少驾驶事故的出现。
ADL1可以表示应用会吸引驾驶员小部分注意力。在一个应用启动阶段或运行阶段的ADL为ADL1的情况下,这一个应用启动或运行会对驾驶员产生干扰,但干扰很小。驾驶员能将大部分注意力投入车辆驾驶,及时处理突发状况。
ADL2可以表示应用会吸引驾驶员部分注意力。在一个应用启动阶段或运行阶段的ADL为ADL2的情况下,这一个应用启动或运行会对驾驶员产生干扰。但驾驶员仍能将部分注意力投入车辆驾驶,及时处理非极端突发状况。
ADL3可以表示应用会吸引驾驶员大部分注意力。在一个应用启动阶段或运行阶段的ADL为ADL3的情况下,这一个应用启动或运行会对驾驶员产生干扰,且干扰较大。驾驶员仅能将小部分注意力投入车辆驾驶,难以及时处理突发状况,导致驾驶员无法实现安全驾驶。
ADL4可以表示应用会吸引驾驶员的主要注意力。当驾驶员启动一个在启动阶段的ADL为ADL4的应用或者中控设备运行一个在运行阶段的ADL为ADL4的应用,驾驶员仅能将次要注意力投入车辆驾驶,导致驾驶员只能非高频、非迅速响应驾驶操作请求。
ADL5可以表示应用会完全吸引驾驶员的注意力。当驾驶员启动一个在启动阶段的ADL为ADL5的 应用或者中控设备运行一个在运行阶段的ADL为ADL5的应用,驾驶员通常会将所有的注意力放在这一个应用上,而难以投入注意力在车辆驾驶上,这导致驾驶员完全无法进行车辆驾驶。
需要进行说明的是,ADL划分为上述六个等级ADL 0~ADL 5仅为示例性说明,不应对本申请构成限定。根据应用对驾驶员注意力分散程度的不同,ADL还可以划分为更多或更少的等级。
中控设备可以评估应用在启动阶段的ADL为哪一个等级,以及应用在运行阶段的ADL为哪一个等级。然后,中控设备可以存储应用在启动阶段和运行阶段的ADL。这样,当中控设备检测到车辆行驶过程中的ARL变化时,中控设备可以查询应用的ADL,从而快速确定是否隐藏应用。
示例性的,中控设备可以结合应用类别以及应用在启动阶段的操作复杂度来评估应用在启动阶段的ADL。
下面以ADL包括六个等级ADL0~ADL5为例,说明中控设备评估应用在启动阶段的ADL的不同情况。
(1)当检测到启动应用的操作简单,且应用为驾驶辅助类应用,中控设备可以确定应用在启动阶段的ADL为ADL0。其中,上述启动应用的操作简单可以表示操作单一,或者为简单动作的重复,或者为语音操作。例如,通过语音指令启动行车模式切换应用,实现语音切换行车模式操作简单,且行车模式切换应用为驾驶辅助类应用,则语音切换行车模式的ADL可以为ADL0。语音切换行车模式的ADL属于行车模式切换应用在启动阶段的ADL。
(2)当检测到启动应用的操作简单,且应用为非驾驶辅助类应用(如车辆控制类应用、生活娱乐类应用),中控设备可以确定应用在启动阶段的ADL为ADL1。例如,通过语音指令启动车窗控制应用,实现语音打开车窗操作简单,且车窗控制应用为车辆控制类应用(即非驾驶辅助类应用),则语音指令操作打开车窗的ADL可以为ADL1。语音指令操作打开车窗的ADL属于车窗控制应用在启动阶段的ADL。
(3)当检测到启动应用的操作中等复杂,且应用为驾驶辅助类应用,中控设备可以确定应用在启动阶段的ADL为ADL1。其中,上述启动应用的操作中等复杂可以表示操作为多个简单动作无规律组合,或者需要简单动脑进行决策。例如,通过语音指令启动导航应用,并实现语音设置导航路线,需要驾驶员决策导航目的地。上述操作中等复杂,且导航应用为驾驶辅助类应用,语音启动和设置导航路线的ADL可以为ADL1。语音启动和设置导航路线的ADL属于导航应用在启动阶段的ADL。
(4)当检测到启动应用的操作中等复杂,且应用为非驾驶辅助类应用,中控设备可以确定应用在启动阶段的ADL为ADL2。例如,通过触摸中控屏上的音乐应用图标实现手动启动音乐应用,需要驾驶员在中控屏上寻找音乐应用图标,并腾出手来触摸音乐应用图标。上述操作中等复杂,且音乐应用为生活娱乐类应用(即非驾驶辅助类应用),则语音启动音乐应用的ADL可以为ADL2。语音启动音乐应用的ADL属于音乐应用在启动阶段的ADL。
(5)当检测到启动应用的操作复杂,且应用为驾驶辅助类应用,中控设备可以确定应用在启动阶段的ADL为ADL2。上述启动应用的操作复杂可以表示操作有一定的技巧要求或者需要复杂的动脑决策。例如,在中控屏显示的导航应用界面上手动输入地点,以设置导航路线,需要驾驶员在中控屏上指定位置处进行文字编辑。上述操作复杂,且导航应用为驾驶辅助类应用,则手动输入地点设置导航路线的ADL可以为ADL2。手动输入地点设置导航路线的ADL属于导航应用启动阶段的ADL。
(6)当检测到启动应用的操作复杂,且应用为非驾驶辅助类应用,中控设备可以确定应用在启动阶段的ADL为ADL3。例如,在中控屏上对游戏应用进行初始化设置,需要驾驶员查找游戏应用中进行初始化设置的操作控件,并腾出手来点击中控屏上的操作控件。上述操作复杂,且游戏应用为生活娱乐类应用(即非驾驶辅助类应用),则对游戏应用进行初始化设置的ADL可以为ADL3。对游戏应用进行初始化设置的ADL属于游戏应用启动阶段的ADL。
需要进行说明的是,上述在判断操作复杂度时将操作复杂度划分为简单、中等难度、复杂仅为示例性说明,不应对本申请构成限定。操作复杂度还可以按照其它的划分方法进行划分。
中控设备可以根据应用在运行过程中是否需要用户操作、操作复杂度、对驾驶员的注意力吸引程度、应用类别来评估应用在运行阶段的ADL。
下面以ADL包括六个等级ADL0~ADL5为例,示例性说明中控设备评估应用在运行阶段的ADL的不同情况。
(1)在应用在运行过程中需要用户操作的情况下,中控设备可以检测操作复杂度。中控设备可以结合应用在运行阶段的操作复杂度和应用类别来评估应用在运行阶段的ADL。其中,应用在运行阶段的操作复杂度越高,驾驶员在应用处于运行阶段时对应用进行操作需要投入的注意力越大。那么,应用在运行阶 段对驾驶员注意力的分散程度越大,即应用在运行阶段的ADL也越大。
(1.1)当检测到应用在运行阶段的操作简单,且应用为驾驶辅助类应用,控设备可以确定应用在运行阶段的ADL为ADL0。例如,语音控制运行阶段的导航应用切换导航路线,需要驾驶员在导航应用提供的多个导航路线选项中选择一个导航路线。上述操作简单,且导航应用为驾驶辅助类应用,则语音切换导航路线的ADL为ADL0。语音切换导航路线的ADL属于导航应用在运行阶段的ADL。
(1.2)当检测到应用在运行阶段的操作简单,且应用为非驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL1。例如,语音控制运行阶段的音乐应用切换歌曲,需要驾驶员说出指定的切换歌曲的语音指令。上述操作简单,且音乐应用为生活娱乐类应用(即非驾驶辅助类应用),则语音切换歌曲的ADL可以为ADL1。语音切换歌曲的ADL属于音乐应用在运行阶段的ADL。
(1.3)当检测到应用在运行阶段的操作中等复杂,且应用为驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL2。例如,使用后视镜调节应用调节后视镜,需要驾驶员观察后视镜并将后视镜调整至合适的方位。上述操作中等复杂,且后视镜调节应用为驾驶辅助类应用,则调节后视镜的ADL可以为ADL2。调节后视镜的ADL属于后视镜调节应用在运行阶段的ADL。
(1.4)当检测到应用在运行阶段的操作中等复杂,且应用为非驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL3。例如,使用语音电话应用进行语音通话,需要驾驶员与通话对端语音沟通。上述语音沟通为中等复杂的操作,且语音电话应用为生活娱乐类应用(即非驾驶辅助类应用),则语音通话的ADL可以为ADL3。语音通话的ADL属于语音电话应用在运行阶段的ADL。
(1.5)当检测到应用在运行阶段的操作复杂,且应用为驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL4。
(1.6)当检测到应用在运行阶段的操作复杂,且应用为非驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL5。例如,使用信息应用手动编辑信息,需要驾驶员在中控屏上指定位置处进行文字编辑。上述操作复杂,且信息应用为生活娱乐类应用,在手动编辑信息的ADL可以为ADL5。手动编辑信息的ADL属于信息应用在运行阶段的ADL。
上述判断操作复杂度为简单、中等复杂、复杂中的一种情况的方法可以参考前述评估启动应用的操作复杂度的方法。这里不再赘述。
(2)在应用在运行过程中不需要用户操作的情况下,中控设备可以判断应用在运行过程中是否会产生视觉吸引以及视觉吸引或非视觉吸引的影响时长。中控设备可以结合应用在运行过程中产生的视觉吸引或非视觉吸引的影响时长以及应用类别来评估应用在运行阶段的ADL。其中,应用在运行阶段产生的视觉吸引或非视觉吸引的影响时长越长,驾驶员在应用处于运行阶段时对应用进行操作需要投入的注意力越大。那么,应用在运行阶段对驾驶员注意力的吸引程度越大,即应用在运行阶段的ADL也越大。
(2.1)当检测到应用在运行阶段会对用户产生短时间的视觉吸引,且应用为驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL0。例如,倒车辅助应用在车辆倒车时显示倒车影像,会在驾驶员倒车时对驾驶员产生短时间视觉吸引。上述倒车辅助应用为驾驶辅助类应用,显示倒车影像的ADL可以为ADL0。显示倒车影像的ADL属于倒车辅助应用在运行阶段的ADL。
(2.2)当检测到应用在运行阶段会对用户产生短时间的视觉吸引,且应用为非驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL1。例如,信息应用显示信息提示,会对驾驶员产生短时间视觉吸引。上述信息应用为生活娱乐类应用(即非驾驶辅助类应用),显示信息提示的ADL可以为ADL1。显示信息提示的ADL属于信息应用在运行阶段的ADL。
(2.3)当检测到应用在运行阶段会对用户产生长时间的视觉吸引,且应用为驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL1。例如,导航应用显示导航路线,会对驾驶员产生长时间视觉吸引。导航应用为驾驶辅助类应用,显示导航路线的ADL可以为ADL1。显示导航路线的ADL属于导航应用在运行阶段的ADL。
(2.4)当检测到应用在运行阶段会对用户产生长时间的视觉吸引,且应用为非驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL2。例如,视频应用播放视频,会对驾驶员产生长时间视觉吸引。视频应用为生活娱乐类应用(即非驾驶辅助类应用),播放视频的ADL可以为ADL2。播放视频的ADL属于视频应用在运行阶段的ADL。
(2.5)当检测到应用在运行阶段会对用户产生短时间的非视觉吸引,且应用为驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL0。例如,倒车辅助应用在车辆倒车时可以提供倒车语音提示,会在驾驶员倒车时对驾驶员产生短时间的听觉吸引(即非视觉吸引)。倒车辅助应用为驾驶辅助类应用, 提供倒车语音提示的ADL可以为ADL0。提供倒车语音提示的ADL属于倒车辅助应用在运行阶段的ADL。
(2.6)当检测到应用在运行阶段会对用户产生短时间的非视觉吸引,且应用为非驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL1。例如,天气应用语音播报天气信息,会对驾驶员产生短时间的听觉吸引。天气应用为生活娱乐类应用(即非驾驶辅助类应用),语音播报天气信息的ADL可以为ADL1。语音播报天气信息的ADL属于天气应用在运行阶段的ADL。
(2.7)当检测到应用在运行阶段会对用户产生长时间的非视觉吸引,且应用为驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL0。例如,驾驶辅助应用在车辆行驶过程中在跟车距离过近、车道偏离等情况下进行语音播报,以辅助驾驶员驾驶。上述辅助驾驶员驾驶的语音播报可持续性存在于全程驾驶的过程中,会对驾驶员产生长时间的听觉吸引。可以理解的,上述辅助驾驶员驾驶的语音播报不会对驾驶员产生视觉吸引,从而不会影响驾驶员在车辆驾驶过程中观察车辆周边的路况,以及时应对各种突发状况。并且,上述辅助驾驶员驾驶的语音播报可以提示驾驶员将注意力放在车辆驾驶上,不会将驾驶员的注意力分散到车辆驾驶以外的方面。因此,上述辅助驾驶员驾驶的语音播报的ADL可以为ADL0。辅助驾驶员驾驶的语音播报的ADL属于驾驶辅助应用在运行过程中的ADL。
(2.8)当检测到应用在运行阶段会对用户产生长时间的非视觉吸引,且应用为非驾驶辅助类应用,中控设备可以确定应用在运行阶段的ADL为ADL1。例如,音乐应用播放音乐,会对驾驶员产生长时间的听觉吸引。音乐应用为生活娱乐类应用(即非驾驶辅助类应用),播放音乐的ADL可以为ADL1。播放音乐的ADL属于音乐应用在运行阶段的ADL。
需要进行说明的是,本申请实施例对应用在运行阶段视觉吸引或非视觉吸引的影响时长的判断方法不作限定。在一种可能的实现方式中,中控设备可以根据影响时长是否超过预设的时长阈值来确定影响时长的长短。当影响时长超过预设的时长阈值,中控设备可以确定该影响时长较长。当影响时长不超过预设的时长阈值,中控设备可以确定该影响时长较短。上述预设的时长阈值可以例如是10秒、20秒、1分钟等等取值。本申请实施例对上述时长阈值的大小不作限定。
上述在介绍评估应用在启动阶段的ADL和应用在运行阶段的ADL所提及的应用仅为示例性说明,不应对本申请构成限定。
上述评估应用在启动阶段的ADL的具体大小,以及应用在运行阶段的ADL的具体大小仅为本申请示例性说明,不应对本申请构成限定。不限于使用应用在启动阶段的操作复杂度、应用类别,采用其它因素来评估应用在启动阶段的ADL的方法,只要基于本申请提供的同一发明思想,都在本申请保护范围内。不限于使用应用在运行阶段是否需要用户操作、操作复杂度、对驾驶员的注意力吸引程度、应用类别,采用其它因素来评估应用在运行阶段的ADL的方法,只要基于本申请提供的同一发明思想,都在本申请保护范围内。
在一些实施例中,一个应用在启动阶段的ADL可以有多个。
一个应用可以具有多种不同的启动方式。例如,中控屏上显示有应用的应用图标。响应于作用在应用图标上的触摸操作,中控屏可以启动该应用。中控屏还可以响应于用于启动应用的语音指令,启动该应用。
其中,不同的启动方式所需要用户进行的操作不同,从而对驾驶员注意力的分散程度可能也不同。例如,通过应用图标启动应用的方式需要驾驶员在中控上寻找应用图标,并进行触摸操作。上述启动方法的操作复杂度显然比通过语音指令启动应用的操作复杂度低。也即是说,应用在启动阶段的ADL可包括基于应用图标启动应用的ADL和基于语音指令启动应用的ADL。上述基于应用图标启动应用的ADL大于基于语音指令启动应用的ADL。
在一些实施例中,中控设备可以根据评估得到的ARL和应用隐藏策略,在中控屏上隐藏应用图标,但保持语音指令启动应用的功能能够使用。这样,驾驶员没有在中控屏对该应用图标进行操作的机会,从而不会因为触摸该应用图标来启动应用而分散注意力。但驾驶员仍能通过语音指令启动该应用。
在另一些实施例中,中控设备可以根据评估得到的ARL和应用隐藏策略,在中控屏上隐藏应用图标,且关闭语音指令启动应用的功能。
由上述实施例可知,中控设备100可以根据应用在不同启动方式下对应的启动阶段的ADL,实现隐藏部分启动ADL的入口,而开放另一部分启动ADL的入口。这可以避免驾驶员使用分散注意力程度较高的方式启动应用,从而使得驾驶员能够在车辆驾驶上投入足够的注意力,提高驾驶安全。
在一些实施例中,一个应用在运行阶段的ADL可以有多个。
一个应用可以提供多项功能。例如,信息应用可以提供在收到信息时,显示信息提示的功能,还可以 提供编辑并发送信息的功能。
其中,一个应用提供的不同功能对驾驶员注意力的分散程度可能不同。那么,一个应用在运行阶段的ADL可包括这一个应用提供的多个功能在运行阶段的多个ADL。例如,信息应用显示信息提示通常会对驾驶员产生短时间的视觉吸引,对驾驶员注意力的分散程度较小。但信息应用提供的编辑并发送信息的功能需要驾驶员在中控屏上指定位置处进行文字编辑,这对驾驶员注意力的分散程度较大。可以看出,信息应用在运行阶段的ADL可包括显示信息提供的功能的ADL和编辑并发送信息的功能的ADL。上述显示信息提供的功能的ADL小于编辑并发送信息的功能的ADL。
在一种可能的实现方式中,中控设备可以根据一个应用包含的多个功能在运行阶段的ADL,来确定这一个应用在运行阶段的ADL。例如,中控设备可以将这一个应用中ADL最大的功能的ADL确定为这一个应用在运行阶段的ADL。本申请实施例对根据一个应用包含的多个功能在运行阶段的ADL确定这一个应用在运行阶段的ADL的方法不作限定。中控设备可以根据评估得到的ARL,来判断应用在运行阶段的ADL是否过大,使得驾驶员难以将足够的注意力投入车辆驾驶。然后,中控设备可以隐藏上述在运行阶段的ADL过大的应用,即拒绝运行该应用。其中,若该应用正在运行,则上述拒绝运行该应用可以表示中控设备停止运行该应用。若该应用未处于运行阶段,则上述拒绝运行该应用可以表示中控设备拒绝响应用户启动该应用的操作。
在另一种可能的实现方式中,中控设备可以对一个应用提供的各项功能单独隐藏。即一个应用中一项功能被隐藏不会影响驾驶员使用这一个应用中的其它功能。中控设备可以根据评估得到的ARL,分别来判断应用中多个功能在运行阶段的ADL是否过大,使得驾驶员难以将足够的注意力投入车辆驾驶。然后,中控设备可以隐藏应用中在运行阶段的ADL过大的功能,即拒绝提供该功能。其中,若上述在运行阶段的ADL过大的功能正处于运行阶段,则上述拒绝提供该功能可以表示中控设备停止运行该功能对应的应用程序,关闭该功能。若上述在运行阶段的ADL过大的功能未处于运行阶段,则上述拒绝提供该功能可以表示中控设备拒绝响应用户启动该功能的操作。
可以理解的,驾驶员的注意力是有限的,当驾驶员在中控设备的应用上投入过多的注意力,则可能难以投入足够的注意力在车辆驾驶上。难以投入足够的注意力在车辆驾驶上可以表示,在驾驶员的部分注意力被车辆驾驶以外的方面(如中控设备的应用)吸引后,驾驶员能够在车辆驾驶上投入的注意力少于评估得到的ARL要求的注意力。在难以投入足够的注意力在车辆驾驶上的情况下,驾驶员难以及时应对突发状况,容易出现驾驶事故。
因此,车辆驾驶对驾驶员注意力的要求越高,则驾驶员应该在车辆驾驶以外的其它方面投入越少的注意力。也即是说,ARL越大,中控设备可以隐藏越多ADL更小的应用,未被隐藏的应用的ADL越小。其中,中控设备隐藏越多ADL更小的应用可包括:在中控屏上隐藏越多在启动阶段ADL更小的应用的应用图标,停止运行越多在运行阶段ADL更小的应用。
在一些实施例中,在车内前排仅有驾驶员的情况下,中控设备一般由驾驶员控制和使用。考虑到中控设备的应用对驾驶员注意力的影响,中控设备可以根据评估得到的ARL和应用的ADL隐藏一个或多个应用,从而减少驾驶员将注意力投入中控设备上的应用的机会。
请参见图1,图1示例性示出了在车内前排仅有驾驶员的情况下,中控设备隐藏应用的场景示意图。
如图1所示,界面211示例性示出了车辆在驾驶状态为状态1时,中控设备的中控屏上显示的应用图标数量。界面212示例性示出了车辆在驾驶状态为状态2时,中控设备的中控屏上显示的应用图标数量。界面213示例性示出了车辆在驾驶状态为状态3时,中控设备的中控屏上显示的应用图标数量。其中,在驾驶状态从上述状态1变化为状态2,再变化为状态3的过程中,车辆驾驶对驾驶员注意力的要求是逐渐增加的。即状态1对应的ARL小于状态2对应的ARL。状态2对应的ARL小于状态3对应的ARL。
对比界面211、界面212和界面213可知,中控屏上显示的应用随着ARL的提升而逐渐减少。其中,中控设备可以根据ARL和应用在启动阶段的ADL(如基于应用图标启动应用的ADL),将启动阶段的ADL过大的应用的应用图标隐藏。这样可以在驾驶过程中需要驾驶员投入的注意力增加时,减少中控屏上显示的应用图标,从而减少驾驶员因为操作中控屏上的应用图标而分散注意力,难以投入足够的注意力在车辆驾驶上的情况。
相反的,中控屏上显示的应用可以随着ARL的减小而逐渐增多。这样,在驾驶员仅需在车辆驾驶上投入少量注意力即可保证安全驾驶的情况下,中控设备可以显示更多的应用图标以便驾驶员能够使用中控设备上的应用。上述方法在判断出驾驶员能分散出足够的注意力使用中控设备上的应用时,仍能将应用提 供给驾驶员使用,不会影响驾驶员使用中控设备上的应用的使用体验。
例如,上述状态1对应的驾驶状态为车辆静止的驾驶状态,则中控设备可以在中控屏上显示中控设备中所有应用的应用图标。在上述驾驶状态从上述状态1变化为状态2,再变化为状态3的过程中,车辆的行驶速度逐渐增加,而其它影响ARL评估的因素基本不变,则中控设备可以确定ARL在逐渐增大,将更多在启动阶段的ADL更小的应用的应用图标隐藏。可以看出,中控屏上显示的应用图标的数量可以随着行驶速度的增加而减少。
再例如,上述状态1对应的驾驶状态为自动驾驶模式开启,且自动驾驶模式的层级处于最高层级的驾驶状态。在自动驾驶模式的层级处于最高层级的情况下,驾驶员在车辆行驶过程中可以无需进行任何驾驶操作。中控设备在驾驶状态为状态1时,可以在中控屏上显示中控设备中所有应用的应用图标。在上述驾驶状态从上述状态1变化为状态2,再变化为状态3的过程中,车辆自动驾驶模式的层级在逐渐下降,驾驶过程中需要驾驶员进行驾驶的操作越来越多,而其它影响ARL评估的因素基本不变,则中控设备可以确定ARL在逐渐增大,将更多在启动阶段的ADL更小的应用的应用图标隐藏。可以看出,中控屏上显示的应用图标的数量可以随着自动驾驶模式层级的下降而减少。
此外,在图1所示驾驶状态从上述状态1变化为状态2,再变化为状态3的过程中,ARL逐渐提升,中控设备还可以停止运行更多在运行阶段的ADL更小的应用。即中控设备中运行的应用随着ARL提升而减少。例如,在ARL为ARL0时,中控设备可运行有导航应用、视频应用。当检测到ARL增大,例如ARL增大为ARL4,中控设备可以停止运行视频应用。上述方法可以通过关闭部分正在运行来实现敦促驾驶员将更多的注意力投入车辆驾驶,这可以减少视频应用在运行过程中多度分散驾驶员的注意力的情况,提高驾驶安全。
由图1所示的场景可知,中控设备可以实时检测车辆驾驶需要驾驶员投入注意力多少的变化。当检测到车辆驾驶需要驾驶员投入的注意力增加,中控设备可以减少中控屏上显示的应用图标的数量,减少中控设备中正在运行的应用的数量。这可以避免驾驶员的注意力被中控设备上的应用过度分散,难以投入足够的注意力在车辆驾驶上。
在一些实施例中,在车内前排不止有驾驶员的情况下(如车内前排同时有驾驶员和副驾驶员),中控设备一般由驾驶员和副驾驶员共同控制和使用。考虑到中控设备的应用对驾驶员注意力的影响,中控设备可以根据评估得到的ARL和应用的ADL隐藏一个或多个应用,从而减少驾驶员将注意力投入中控设备上的应用的机会。
不过,车辆驾驶可以无需副驾驶员投入注意力。为了减少隐藏应用对副驾驶员使用中控设备的影响,中控设备在车内前排同时有驾驶员和副驾驶员的情况下隐藏的应用数量,可以比车辆在相同行驶状态下但车内前排仅有驾驶员的情况下更少。
请参见图2,图2示例性示出了在车内前排同时有驾驶员和副驾驶员的情况下,中控设备隐藏应用的场景示意图。
如图2所示,界面221示例性示出了车辆在驾驶状态为状态1时,中控设备的中控屏上显示的应用图标数量。界面222示例性示出了车辆在驾驶状态为状态2时,中控设备的中控屏上显示的应用图标数量。界面223示例性示出了车辆在驾驶状态为状态3时,中控设备的中控屏上显示的应用图标数量。其中,在驾驶状态从上述状态1变化为状态2,再变化为状态3的过程中,车辆驾驶对驾驶员注意力的要求是逐渐增加的。即状态1对应的ARL小于状态2对应的ARL。状态2对应的ARL小于状态3对应的ARL。
对比界面221、界面222和界面223可知,中控屏上显示的应用随着ARL的提升而逐渐减少。其中,中控设备可以根据ARL和应用在启动阶段的ADL(如基于应用图标启动应用的ADL),将启动阶段的ADL过大的应用的应用图标隐藏。这样可以在驾驶过程中需要驾驶员投入的注意力增加时,减少中控屏上显示的应用图标,从而减少驾驶员因为操作中控屏上的应用图标而分散注意力,难以投入足够的注意力在车辆驾驶上的情况。
上述状态1可以例如是ARL为ARL0对应的驾驶状态。在处于状态1时,无论车内前排是否仅有驾驶员,中控设备均可以在中控屏上显示中控设备中所有应用的应用图标。对比图1所示的界面211和图2所示的界面221可知,在处于状态1时,中控设备在车内前排仅有驾驶员和车内前排同时有驾驶员和副驾驶员的情况下可以全量显示应用图标。
当从状态1变化为状态2,ARL增大,中控设备可以减少中控屏上显示的应用图标。对比图1所示的界面212和图2所示的界面222可知,在处于状态2时,中控设备在车内前排同时有驾驶员和副驾驶员的 情况下显示的应用图标多于在车内前排仅有驾驶员的情况下显示的应用图标。从状态1变化为状态2,中控设备在车内前排同时有驾驶员和副驾驶员的情况下减少的应用图标少于在车内前排仅有驾驶员的情况下减少的应用图标。
同样的,当从状态2变化为状态3,ARL增大,中控设备可以减少中控屏上显示的应用图标。对比图1所示的界面213和图2所示的界面223可知,在处于状态3时,中控设备在车内前排同时有驾驶员和副驾驶员的情况下显示的应用图标多于在车内前排仅有驾驶员的情况下显示的应用图标。
此外,在图2所示驾驶状态从上述状态1变化为状态2,再变化为状态3的过程中,ARL逐渐提升,中控设备还可以停止运行更多在运行阶段的ADL更小的应用。即中控设备中运行的应用随着ARL提升而减少。可以理解的,中控设备在车内前排同时有驾驶员和副驾驶员的情况下停止运行的应用数量,可以比ARL提升程度相同时在车内前排仅有驾驶员的情况下停止运行的应用数量少。
由图2所示的场景可知,中控设备可以实时检测车辆驾驶需要驾驶员投入注意力多少的变化。当检测到车辆驾驶需要驾驶员投入的注意力增加,中控设备可以减少中控屏上显示的应用图标的数量,减少中控设备中正在运行的应用的数量。其中,上述应用图标以及正在运行的应用减少的数量均可以比在ARL变化程度相同时在车内前排仅有驾驶员的情况下减少的数量更少。这既可以避免驾驶员的注意力被中控设备上的应用过度分散,驾驶员难以投入足够的注意力在车辆驾驶上,又可以减少应用被隐藏对副驾驶员使用中控设备的影响。
在本申请中,当确定了车辆驾驶的ARL,以及中控设备中各个应用的ADL,中控设备可以根据预设的应用隐藏策略来确定隐藏哪些应用。
在一些实施例中,上述预设的应用隐藏策略可以为应用隐藏策略表。应用隐藏策略表可以参见下述表1。
表1
可以看出上述表1所示的应用隐藏策略表包含在车内前排仅有驾驶员,以及在车内前排同时有驾驶员和副驾驶员两种场景中,在不同的ARL下需要隐藏的应用对应的ADL。中控设备可以根据上述应用隐藏策略表、车辆驾驶的ARL以及应用在启动阶段的ADL,来确定需要在中控屏上隐藏的应用图标。中控设备可以根据上述应用隐藏策略表、车辆驾驶的ARL以及应用在运行阶段的ADL,来确定需要停止运行中控设备中哪些正在运行的应用。
下面以车内前排仅有驾驶员的场景为例进行说明。
例如,当评估得到当前的ARL为ARL2,中控设备可以根据上述表1,在中控屏上隐藏在启动阶段的ADL为ADL4以及为ADL5的应用的应用图标,并且关闭在运行阶段的ADL为ADL4以及为ADL5的应用。
再例如,当评估得到ARL从ARL2增大为ARL3,中控设备可以根据上述表1,进一步在中控屏上隐藏在启动阶段的ADL为ADL3的应用的应用图标,并且关闭在运行阶段的ADL为ADL3的应用。
上述应用隐藏策略表仅为示例性说明,不应对本申请构成限定。
在一些实施例中,上述预设的应用隐藏策略可以为中控设备在判断出应用的ADL大于ARL对应的ADL阈值时,隐藏应用。其中,中控设备中可存储有不同ARL对应的ADL阈值。各个ARL对应的ADL阈值可以是预设的。当判断出应用在启动阶段的ADL大于ARL对应的ADL阈值,中控设备可以在中控屏上隐藏该应用的应用图标。当判断出应用在运行阶段的ADL大于ARL对应的ADL阈值,中控设备可以停止运行该应用。
示例性的:
(1)ARL0对应的ADL阈值
在车内前排仅有驾驶员的场景和在车内前排同时有驾驶员和副驾驶员的场景中,ARL0对应的ADL阈值均可以为ADL5。
(2)ARL1对应的ADL阈值
在车内前排仅有驾驶员的场景中,ARL1对应的ADL阈值可以为ADL4。
在车内前排同时有驾驶员和副驾驶员的场景中,ARL1对应的ADL阈值可以为ADL5。
(3)ARL2对应的ADL阈值
在车内前排仅有驾驶员的场景中,ARL2对应的ADL阈值可以为ADL3。
在车内前排同时有驾驶员和副驾驶员的场景中,ARL2对应的ADL阈值可以为ADL5。
(4)ARL3对应的ADL阈值
在车内前排仅有驾驶员的场景中,ARL3对应的ADL阈值可以为ADL2。
在车内前排同时有驾驶员和副驾驶员的场景中,ARL3对应的ADL阈值可以为ADL4。
(5)ARL4对应的ADL阈值
在车内前排仅有驾驶员的场景中,ARL4对应的ADL阈值可以为ADL1。
在车内前排同时有驾驶员和副驾驶员的场景中,ARL4对应的ADL阈值可以为ADL3。
(6)ARL5对应的ADL阈值
在车内前排仅有驾驶员的场景中,ARL5对应的ADL阈值可以为ADL0。
在车内前排同时有驾驶员和副驾驶员的场景中,ARL5对应的ADL阈值可以为ADL2。
可以看出,ARL对应的ADL阈值可以随着ARL的增大而降低。这样,中控设备可以根据ARL对应的ADL阈值,在ARL越大的情况下,隐藏越多ADL更小的隐藏。在车内前排仅有驾驶员的场景中ARL对应的ADL阈值小于在车内前排同时有驾驶员和副驾驶员的场景中同样的ARL对应的ADL阈值。这样,中控设备可以根据ARL对应的ADL阈值,在ARL相同的情况下,在车内前排同时有驾驶员和副驾驶员的场景中隐藏更少的应用。
可以理解的,上述ADL对应的ADL阈值仅为示例性说明,不应对本申请构成限定。
本申请实施例对上述应用隐藏策略的具体内容不作限定,只要基于本申请提供的同一发明思想,都在本申请保护范围内。
下面介绍本申请实施例提供的一种车辆的结构示意图。
参考图3,图3示例性示出了本申请实施例提供的车辆200的结构示意图。
如图3所示,车辆200包括:控制器局域网络(controller area network,CAN)总线21、多个电子控制单元(electronic control unit,ECU)、发动机23、车载盒子(telematics box,T-box)24、变速器25、行车记录仪26、防抱死系统(antilock brake system,ABS)27、传感器系统28、摄像系统29,麦克风30,自动驾驶系统31和行车模式管理系统32等等。
CAN总线21是支持分布式控制或实时控制的串行通信网络,用于连接车辆200的各个部件。在CAN总线21上的任何部件都可以监听到CAN总线21上传输的所有数据。CAN总线21传输的帧可以包含数据帧、远程帧、错误帧、过载帧,不同的帧传输不同类型的数据。在本申请实施例中,CAN总线21可用于传输各个部件在基于中控设备100的应用控制方法中涉及到的数据(如车速、行车模式、自动驾驶层级、道路拥堵程度等驾驶信息),该方法的具体实现可参考后文方法实施例的详细描述。
不限于CAN总线21,在其他一些实施例中,车辆200的各个部件还可以通过其他方式来连接及通信。如,各个部件还可以通过车载以太网(ethernet)局域互联网络(local interconnect network,LIN)总线、FlexRay及常用车载网络系统(media oriented systems,MOST)总线等等通信,本申请实施例对此不做限制。以下实施例以各个部件通过CAN总线21通信进行说明。
自动驾驶系统31可用于提供自动驾驶功能。其中,自动驾驶系统31可以提供不同层级的自动驾驶模式。自动驾驶模式的层级越高,驾驶员在驾驶过程中需要进行的驾驶操作越少,驾驶员需要在车辆驾驶上投入的注意力也可以越少。
行车模式管理系统32可用于提供管理车辆200的驾驶模式的功能。其中,车辆200的驾驶模式可以包括运动模式、标准模式、节能模式等等。当车辆200切换驾驶模式时,行车模式管理系统32可以通过改变发动机23喷油嘴喷油量和变速箱工作逻辑来调整车辆的动力输出。车辆200处于不同的驾驶模式,需要驾驶员在车辆驾驶上投入的注意力通常也不同。
ECU相当于车辆200的处理器或大脑,用于根据从CAN总线21上获取的指令或者根据用户输入的操作,指示对应的部件执行相应的动作。ECU可以由安全芯片、微处理器((microcontroller unit,MCU)、随机存取存储器(random access memory,RAM)、只读存储器(random-only memory,ROM)、输入/输出接口(I/O)、模拟/数字转换器(A/D转换器)以及输入、输出、整形、驱动等大规模集成电路组成。

在本申请中,T-box24中可安装有应用,并通过安装的应用来提供多种服务。T-box24可以控制上述应 用,根据车辆驾驶对驾驶员注意力的要求来隐藏一个或多个应用,从而减少上述应用对驾驶员注意力的影响,提高驾驶安全。
变速器ECU22C用于管理变速器。
变速器25可以用来改变发动机的转速和转矩的机构,它能固定或分档改变输出轴和输入轴传动比。变速器25组成部分可以包含变速传动机构、操纵机构以及动力输出机构等。变速传动机构的主要作用是改变转矩和转速的数值和方向;操纵机构的主要作用是控制传动机构,实现变速器传动比的变换,即实现换档,以达到变速变矩。
行车记录仪ECU22D用于管理行车记录仪26。
行车记录仪26组成部分可以包括主机、车速传感器、数据分析软件等。行车记录仪26是指记录车辆行驶途中的影像及声音包括行车时间、速度、所在位置等相关资讯的仪器。在本申请实施例中,当车辆行驶时,车速传感器采集到车轮转速,并将车速信息通过CAN总线发送给行车记录仪26。

本申请实施例涉及的中控设备可以上述图3所示车辆200中的T-box24。中控设备功能可以参考前述图3所示实施例的介绍。
下面具体介绍本申请提供的一种中控设备的结构示意图。
请参照图4,图4示例性示出了本申请实施例提供的中控设备100的结构示意图。
中控设备100可包括应用生命周期管理模块410、应用信息管理模块420、应用图标管理模块430、驾驶注意力要求等级评估模块440和驾驶信息收集模块450。其中:
应用生命周期管理模块410可用于管理应用的启动、运行以及关闭。响应于启动应用的操作,应用生 命周期管理模块410可以为启动该应用,为该应用创建进程。响应于关闭应用的操作,应用生命周期管理模块410可以结束该应用的进程。生命周期可以指应用的进程从创建到结束的过程。在一些实施例中,应用生命周期管理模块410可以为一个应用创建多个进程。这多个进程可以是分别独立的,分别对应这一个应用中的多个功能。一个进程的生命周期结束可以不影响同一个应用中其它进程的运行。
应用信息管理模块420可用于管理并存储中控设备100中所有应用的信息。例如,应用的名称、应用图标、开发者、类别、应用在启动阶段的ADL、应用在运行阶段的ADL等等。在一些实施例中,应用有多种不同的启动方式。应用信息管理模块420可包含应用在按照不同启动方式在启动阶段的ADL。在一些实施例中,应用可提供多项功能。应用信息管理模块420可包含应用中不同功能在运行阶段的ADL。
其中,在一种可能的实现方式中,当中控设备100安装一个应用,中控设备100可以评估这一个应用在启动阶段的ADL和在运行阶段的ADL。然后,中控设备100中的应用信息管理模块420可以存储这一个应用在启动阶段的ADL和在运行阶段的ADL,以便于后续在驾驶过程中判断是否隐藏这一个应用。
在另一种可能的实现方式中,各个应用在启动阶段的ADL和在运行阶段的ADL可以是由其它设备评估的,例如,可以是由云服务器评估的。云服务器中可以存储有各个应用在启动阶段的ADL和在运行阶段的ADL。当中控设备100安装一个应用,中控设备100可以向云服务器获取这一个应用在启动阶段的ADL和在运行阶段的ADL,并存储上述ADL。本申请实施例对中控设备100得到应用在启动阶段的ADL和在运行阶段的ADL的方法不作限定。
应用图标管理模块430可用于管理中控屏上显示的应用图标。例如,应用图标管理模块430可以调整应用图标在中控屏上显示的位置、大小、显示样式。并且,应用图标管理模块430可以在中控屏上隐藏或恢复显示应用图标。上述应用图标可用于启动应用图标对应的应用。
驾驶信息收集模块450可用于收集车辆200在驾驶过程中的驾驶信息。上述驾驶信息可包括以下一项或多项:车速、行车模式、是否开启自动驾驶模式、自动驾驶模式的层级、道路类型(如城市道路、乡村山路、高度公路等)、道路的曲直程度、路上行人的数量、路上车辆的数量、道路的拥堵程度等等。其中,中控设备100的驾驶信息收集模块450可以向前述图3所示车辆200的行车记录仪26、传感器系统28、摄像系统29、自行驾驶系统31、行车模式管理系统32等部件获取驾驶信息。本申请实施例对驾驶信息收集模块450获取上述驾驶信息的实现方式不作限定。
驾驶注意力要求等级评估模块(ARL评估模块)440可用于根据驾驶信息收集模块450收集的驾驶信息,评估车辆驾驶的ARL,以便确定当前车辆驾驶对驾驶员注意力要求的高低。驾驶注意力要求等级评估模块440评估ARL的实现方法可以参考前述实施例对评估ARL的介绍。这里不再赘述。
可以理解的是,本申请实施例示意的结构并不构成对中控设备100的具体限定。中控设备100可以包括比图4所示更多或更少的模块,或者组合某些模块,或者拆分某些模块。
在本申请中,ARL评估模块440可以定时或不定时评估车辆驾驶的ARL。当ARL发生变化,ARL评估模块440可以将评估得到的ARL发送给应用生命周期管理模块410以及应用图标管理模块430。应用生命周期管理模块410可以向应用信息管理模块420获取中控设备100中当前正在运行的应用在运行阶段的ADL。根据接收到的ARL、应用在运行阶段的ADL以及应用隐藏策略,应用生命周期管理模块410可以关闭在运行阶段的ADL过大的应用。例如,应用生命周期管理模块410可以关闭在运行阶段的ADL超过ARL对应的ADL阈值的应用。应用图标管理模块430可以向应用信息管理模块420获取应用在启动阶段的ADL。根据接收到的ARL、应用在启动阶段的ADL以及应用隐藏策略,应用图标管理模块430可以在中控屏上隐藏在启动阶段的ADL过大的应用的应用图标。例如,应用图标管理模块430可以在中控屏上隐藏在启动阶段的ADL超过ARL对应的ADL阈值的应用的应用图标。
这样可以避免驾驶员的注意力被过多分散在中控设备的应用上,使得驾驶员在不同的驾驶状况下均能在车辆驾驶上投入足够的注意力,提高驾驶安全。
基于前述图3所示的车辆200以及图4所示的中控设备100,下面介绍本申请实施例提供的一种应用控制的场景。
图5A和图5B示例性示出了一种中控设备100控制应用的场景示意图。
如图5A所示,在驾驶员驾驶车辆的过程中,中控设备100可以在中控屏上显示用户界面510。用户界面510可包含应用图标显示区域511。应用图标显示区域511可用于显示中控设备100中安装的应用的应用图标。中控设备100可以评估当前车辆驾驶的ARL,并根据ARL、应用在启动阶段的ADL以及应用隐藏策略确定在中控屏上显示哪些应用的应用图标,隐藏哪些应用的应用图标。
例如,中控设备100评估得到当前车辆驾驶的ARL为ARL2。中控设备100可以在中控屏上隐藏在启动阶段ADL超过ARL2对应的ADL阈值的应用的应用图标,显示在启动阶段ADL不超过ARL2对应的ADL阈值的应用的应用图标。图5A所示应用图标显示区域511中的应用图标(如设置应用图标、驾驶模式应用图标、游戏应用图标、视频应用图标等等)对应应用在启动阶段的ADL均不超过上述ARL2对应的ADL阈值。
用户界面510还可包含音乐播放控件512。上述音乐播放控件512可以是音乐应用的一个控件,可用于控制播放的音乐(如暂停播放、继续播放、下一首、上一首)。图5A所示的音乐播放控件512可以指示“歌曲1”正在播放中。即中控设备100正在运行音乐应用,并播放歌曲1。
中控设备100可以根据评估得到的ARL、应用在运行阶段的ADL以及应用隐藏策略确定要停止运行哪些正在运行的应用,继续运行哪些正在运行的应用。
例如,中控设备100评估得到当前车辆驾驶的ARL为ARL2。中控设备100可以停止运行在运行阶段的ADL超过ARL2对应的ADL阈值的应用,继续运行在运行阶段的ADL不超过ARL2对应的ADL阈值的应用。上述音乐应用在运行阶段的ADL不超过ARL2对应的ADL阈值。那么,中控设备100可以在图5A所示的场景中继续运行音乐应用。
驾驶员继续驾驶,从图5A所示的位置行驶到图5B所示的位置。对比图5A和图5B可知,驾驶员在图5A所示的位置处周边车辆行人较少,道路通畅,路况比较简单,需要在车辆驾驶上投入的注意力较少。驾驶员在图5B所示的位置处周边车辆行人较多,即将经过斑马线和红绿灯,道路比较用对,路况比较复杂,需要在车辆驾驶上投入较多注意力,以及时应对突发状况。例如,在图5B所示的位置处,驾驶员需要集中注意力在自身车辆与周边车辆之间的距离,避免跟车距离过近时前车紧急刹车而自己来不及刹车。并且,驾驶员还需要注意观察周边行人的动向,避免行人经过斑马线时无法及时刹车。可以看出,从图5A所示的位置行驶到图5B所示的位置,驾驶员需要在车辆驾驶上投入的注意力增加。那么,中控设备100在车辆位于图5B所示位置评估得到的ARL大于在车辆位于图5A所示位置评估得到的ARL。
例如,中控设备100在车辆位于图5B所示位置评估得到的ARL为ARL4。中控设备100可以在中控屏上隐藏在启动阶段ADL超过ARL2对应的ADL阈值的应用的应用图标,显示在启动阶段ADL不超过ARL2对应的ADL阈值的应用的应用图标。中控设备100根据上述ARL4、应用在启动阶段的ADL和应用隐藏策略显示的应用图标可以参照图5B所示中控设备100在中控屏上显示的用户界面520。
如图5B所示,用户界面520可包含应用图标显示区域521。应用图标显示区域521可包含设置应用图标、驾驶模式应用图标、日历应用图标、行车记录仪应用图标和天气应用图标。图5B所示应用图标显示区域521中的应用图标对应应用在启动阶段的ADL均不超过上述ARL4对应的ADL阈值。
对比图5A所示的应用图标显示区域511和图5B所示的应用图标显示区域521可知,当ARL增大,中控设备100可以在中控屏上隐藏更多在启动阶段ADL更小的应用的应用图标(如图5A所示的游戏应用图标、视频应用图标、备忘录应用图标等等)。这可以避免驾驶员由于操作在启动时会过度分散注意力的应用的应用图标,而难以投入足够的注意力在车辆驾驶上,从而提高驾驶安全。
中控设备100还可以停止运行在运行阶段的ADL超过ARL4对应的ADL阈值的应用,继续运行在运行阶段的ADL不超过ARL4对应的ADL阈值的应用。例如,上述音乐应用在运行阶段的ADL超过ARL4对应的ADL阈值。中控设备100可以停止运行音乐应用。
其中,在一种可能的实现方式中,中控设备100可以关闭音乐应用,结束音乐应用的进程。
在另一种可能的实现方式中,中控设备100可以停止播放音乐,并显示图5B所示的音乐播放控件522。即中控设备100停止运行音乐应用可以是暂时停止播放音乐,但没有结束音乐应用的进程。这样,当中控设备100后续评估得到的ARL降低,中控设备可以再次恢复运行音乐应用的进程。例如,当中控设备100根据评估得到的ARL判断出ARL对应的ADL阈值大于或等于音乐应用在运行阶段的ADL,则中控设备100可以再次运行音乐应用,从上一次暂停的位置处继续播放音乐。上述中控设备100继续播放音乐可以无需用户再次执行启动音乐应用的操作。
在一些实施例中,中控设备100将中控屏上的一个或多个应用图标隐藏后,被隐藏的应用图标所在的位置会出现空缺。中控设备100可以对未被隐藏的应用图标的显示位置进行重新排序。例如,中控设备100可以按照从左至右、从上至下的排列顺序在中控屏上应用图标显示区域逐个显示未被隐藏的应用图标。在另一些实施例中,中控设备100也可以不改变未被隐藏的应用图标的显示位置。
可以理解的,上述图5A和图5B所示的用户界面以及被隐藏的应用图标仅为本申请的示例性说明,不应对本申请的应用控制方法构成限定。
由上述图5A和图5B所示的场景可知,中控设备100可以实时检测车辆驾驶需要驾驶员投入注意力多少的变化。当检测到车辆驾驶需要驾驶员投入的注意力增加,中控设备可以减少中控屏上显示的应用图标的数量,减少中控设备中正在运行的应用的数量。这可以让驾驶员在车辆驾驶过程中没有操作容易分散注意力的应用的机会,避免驾驶员的注意力被中控设备上的应用过度分散,难以投入足够的注意力在车辆驾驶上,从而提高驾驶安全。
在一些实施例中,一个应用可以提供多项功能。不同的功能的ADL可能不同。中控设备100可以评估当前车辆驾驶的ARL,并根据ARL、功能的ADL以及应用隐藏策略将一个应用中的一项或多项功能隐藏。其中,当一个应用中的部分功能被隐藏,驾驶员仍能在继续使用这一个应用中其它未被隐藏的功能。
图6A和图6B示例性示出了一种中控设备100控制应用的场景示意图。
如图6A所示,在驾驶员驾驶车辆的过程中,响应于启动信息应用的操作,中控设备100可以开启信息应用,在中控屏上显示用户界面610。用户界面610可以为信息应用中与联系人“张三”的聊天界面。用户界面610可包括语音控件611、文字编辑控件612、表情控件613和更多功能控件614。其中:
语音控件611可用于提供发送语音消息的功能。响应于对语音控件611的操作,中控设备100可以调用麦克风采集语音,并将语音发送给联系人“张三”。
文字编辑控件612可用于提供发送文字消息的功能。响应于对文字编辑控件612的操作,中控设备100可以在中控屏上显示键盘,以便于用户使用键盘在文字编辑控件中输入文字消息。
表情控件613可用于提供发送表情包的功能。响应于对表情控件613的操作,中控设备100可以显示一个或多个表情包选项,以便于用户选择一个表情。
更多功能控件614可用于触发中控设备100显示信息应用提供的其它功能对应的控件。例如发送视频照片的功能、位置共享的功能、发送文件的功能等等。
也即是说,上述信息应用可以提供发送语音消息的功能、发送文字消息的功能、发送表情包的功能、发送视频照片的功能、位置共享的功能、发送文件的功能等等。其中,使用发送语音消息的功能需要驾驶员对语音控件611进行操作(如点击操作),并说出需要发送的语音。使用发送文字消息的功能需要驾驶员对文字编辑控件612进行操作,并使用中控设备100提供的键盘进行文字编辑。使用发送表情包的功能需要驾驶员对表情控件613进行操作,并选择中控屏上显示的一个或多个表情来发送。上述发送视频照片的功能、位置共享的功能、发送文件的功能均需要驾驶员对更多功能控件614进行操作,然后选择一个功能对应的控件,并进一步执行相应的操作来发送视频照片,或者进行位置共享,或者发送文件。可以看出,发送语音消息的功能的ADL较低。而发送文字消息的功能、发送表情包的功能、送视频照片的功能、位置共享的功能、发送文件的功能的ADL均较高。
如图6A所示,在行驶至图6A所示位置处时,车辆周边的车辆行人较少,道路通畅,路况比较简单,需要在车辆驾驶上投入的注意力较少。也即是说,驾驶员可以在使用中控设备100的应用上投入较多的注意力。中控设备100在运行信息应用时,可以显示图6A所述的用户界面610。驾驶员可以使用信息应用中发送语音消息的功能、发送文字消息的功能、发送表情包的功能、送视频照片的功能、位置共享的功能、发送文件的功能中的任意一个。
驾驶员继续驾驶,从图6A所示的位置行驶到图6B所示的位置。如图6B所示,在行驶至图6B所示位置处时,车辆周边的车辆行人较多,即将经过斑马线和红绿灯,道路比较用对,路况比较复杂,需要在车辆驾驶上投入较多注意力,以及时应对突发状况。也即是说,从图6A所示的位置行驶到图6B所示的位置,车辆驾驶的ARL增大,驾驶员在图6B所示的位置处不应该在使用中控设备100的应用上过多的注意力。中控设备100仍然可以保持信息应用处于运行状态。其中,中控设备100可以根据当前评估得到的ARL、信息应用中各功能的ADL以及应用隐藏策略,确定信息应用中需要隐藏的功能。
例如,中控设备100可以保留上述发送语音消息的功能,而隐藏上述发送文字消息的功能、发送表情包的功能、送视频照片的功能、位置共享的功能、发送文件的功能。中控设备100可以显示图6B所示的用户界面620。用户界面620可包含语音控件611。对比图6A所示的用户界面610和图6B所示的用户界面620可知,当ARL增大,中控设备100在中控屏上隐藏了上述文字编辑控件612、表情控件613和更多功能控件614。这可以避免驾驶员在车辆驾驶过程中由于使用文字编辑控件612、表情控件613和更多功能控件614对应的功能而过度分散注意力,难以在车辆驾驶上投入足够的注意力,从而提高驾驶安全。但由于发送语音消息的功能仅需要驾驶员投入少量注意力,不会导致驾驶员在图6B所示位置处难以在车辆驾驶上投入足够的注意力,因此中控设备100可以保留上述语音控件611。这样,驾驶员仍然能够使用信 息应用中发送语音消息的功能。
在一些实施例中,上述隐藏应用中的功能除了在中控屏上取消显示功能对应的控件,还可以停止运行功能对应的程序。
可以理解的,上述图6A和图6B所示的用户界面以及被隐藏的功能仅为本申请的示例性说明,不应对本申请的应用控制方法构成限定。
由上述图6A和图6B所示的场景可知,中控设备可以单独隐藏一个应用提供的各项功能。一个应用中的一项功能被隐藏可以不影响这一个应用中其它功能的使用。中控设备可以实时检测车辆驾驶需要驾驶员投入注意力多少的变化。当检测到应用中的一项功能的ADL会过度吸引驾驶员的注意力,使得驾驶员能在车辆驾驶上投入的注意力不能满足当前车辆驾驶的ARL的需求,则中控设备100可以将该应用的这一项功能隐藏。这可以避免驾驶员使用该应用的这一项功能而导致注意力被过度分散,从而提高驾驶安全。但驾驶员仍能继续使用该应用中其它未被隐藏的功能。上述方法可以在实现避免驾驶员因使用中控设备上的应用而被过度分散注意力的基础上,减少隐藏应用对驾驶员使用中控设备中应用的影响。
在一些实施例中,中控设备可以根据驾驶信息的变化调整应用图标在中控屏上的显示位置。其中,当驾驶信息变化而使得驾驶员需要在车辆驾驶上投入更多的注意力,中控设备可以将对驾驶员注意力分散程度小的应用的图标显示在中控屏上靠近驾驶员的一侧,并将对驾驶员注意力分散程度大的应用的图标显示在中控屏上远离驾驶员的一侧。
图6C示例性示出了另一种中控设备100控制应用的场景示意图。
这里以驾驶辅助类应用为对驾驶员注意力分散程度小的应用,以非驾驶辅助类应用为对驾驶员注意力分散程度大的应用作为示例进行说明。
如图6C所示,中控设备100可以在中控屏上显示用户界面630。用户界面630可包括中控设备100中应用的图标。例如,驾驶辅助类应用1的图标~驾驶辅助类应用6的图标,以及非驾驶辅助类应用1的图标~非驾驶辅助类应用12。上述驾驶辅助类应用和非驾驶辅助类应用的图标在用户界面630上的显示位置可以是中控设备100在出厂时预设的,或者是由应用的安装顺序确定的,或者是响应于调整图标位置的操作而确定的。
中控设备100可以在车辆行驶的过程中,获取车辆的驾驶信息。当判断出驾驶信息朝着需要驾驶员在车辆驾驶上投入更多注意力的方向上变化,中控设备100可以调整中控屏上应用图标的显示位置。
示例性的,中控设备100可以在中控屏上显示用户界面640。对比用户界面630,用户界面640上应用图标的显示位置发生了变化。其中,中控设备100可以将驾驶辅助类应用1的图标~驾驶辅助类应用6的图标显示在用户界面640的区域641。区域641可以是中控屏上靠近驾驶员一侧的区域。中控设备100可以将非驾驶辅助类应用1的图标~非驾驶辅助类应用12的图标显示在用户界面640的区域641之外的区域。用户界面640的区域641之外的区域可以是中控屏上远离驾驶员一侧的区域。
可以理解的,区域641与驾驶员之间的距离更近。驾驶员对区域641中的应用图标进行操作可以更加方便快捷。这样,在驾驶员需要在车辆驾驶上投入更多注意力的情况下,驾驶员能够快速地对注意力分散程度小的应用的图标进行操作。上述方法将对注意力分散程度大的应用的图标显示在中控屏上远离驾驶员的一侧,可以更好地减少这些应用对驾驶员注意力的影响,从而提高驾驶安全。
上述图6C所示的应用仅为本申请的示例性说明,不应对本申请构成限定。
上述驾驶信息朝需要驾驶员在车辆驾驶上投入更多注意力的方向上变化,可以包括以下一项或多项:车速增大、自动驾驶模式的层级下降、道路的拥堵程度增加、路上行人的数量增加、路上车辆的数量增加、道路的曲直程度增加。
下面对中控设备100根据驾驶信息确定显示应用图标的方式进行介绍。
在一种可能的实现方式中,中控设备100可以获取车辆行驶过程中的驾驶信息,并根据驾驶信息评估ARL。然后,中控设备100可以根据上述ARL和应用的ADL来确定应用图标在中控屏上的显示位置。其中,当ARL增大,中控设备100可以将更多ADL更大的应用的图标移动至中控屏上远离驾驶员一侧的区域,并将更多ADL更小的应用的图标移动至中控屏上靠近驾驶员一侧的区域。
示例性地,中控设备可以将在启动阶段的ADL小于等于当前评估得到的ARL对应的ADL阈值的应用的应用图标移动至中控屏上靠近驾驶员一侧的区域,将在启动阶段的ADL高于上述ADL阈值的应用的应用图标移动至中控屏上远离驾驶员一侧的区域。
在另一种可能的实现方式中,中控设备100中可存储有不同的驾驶信息对应的应用图标显示方式。例 如,上述不同的驾驶信息对应的应用图标显示方式可以存储在应用控制表中。上述应用图标的显示方式可用于指示各个应用图标在中控上的显示位置。当获取到车辆的驾驶信息,中控设备100可以查询应用控制表,以得到当前的驾驶信息对应的应用图标显示方式。中控设备100可以根据上述应用图标显示方式在中控屏上显示各个应用的图标。
上述显示应用图标的方式仅为示例性说明,中控设备100还可以采用其它的方式来根据驾驶信息确定应用图标的显示位置。
在一些实施例中,车辆200中的显示屏有多个。这多个显示屏可以配置在车辆200的不同位置处,并可以由中控设备100统一控制。中控设备100在根据驾驶信息的变化调整应用图标的显示位置时,可以将应用图标调整至这多个显示屏上进行显示。其中,当检测到驾驶信息朝着需要驾驶员在车辆驾驶上投入更多注意力的方向上变化,中控设备100可以将对注意力分散程度小的应用的图标显示在靠近驾驶员一侧的显示屏上,并将对注意力分散程度大的应用的图标显示在远离驾驶员一侧的显示屏上。这样可以减少上述注意力分散程度大的应用对驾驶员注意力的吸引,使得驾驶员可以投入足够的注意力在车辆驾驶上,从而提高驾驶安全。
在一些实施例中,中控设备100除了可以将上述调整应用图标的显示位置的方法与隐藏应用的图标的方法结合。例如,当检测到驾驶信息朝着需要驾驶员在车辆驾驶上投入更多注意力的方向上变化,中控设备100既可以根据上述实施例调整应用图标的显示位置,将一个或多个对注意力分散程度小的应用的图标显示在中控屏上靠近驾驶员的一侧,还可以在中控屏上隐藏一个或多个对注意力分散程度大的应用的图标。在一些实施例中,中控设备100可以根据驾驶信息对应用的用户界面进行调整。一个应用的用户界面中可包含用于提供该应用的多个功能的多个控件。中控设备100可以根据驾驶信息以及应用在提供上述不同功能时对注意力的分散程度,来调整用于提供上述多个功能的多个控件在用户界面上的显示位置。例如,当检测到驾驶信息朝着需要驾驶员在车辆驾驶上投入更多注意力的方向上变化,中控设备100可以将对注意力分散程度小的功能对应的控件显示在靠近驾驶员的一侧,并将对注意力分散程度大的功能对应的控件显示在远离驾驶员的一侧。可选的,中控设备100还可以根据驾驶信息隐藏应用的用户界面中部分功能对应的控件。例如,当检测到驾驶信息朝着需要驾驶员在车辆驾驶上投入更多注意力的方向上变化,中控设备100可以隐藏对注意力分散程度大的功能对应的控件。上述实施例可以减少对注意力分散程度大的功能对驾驶员注意力的吸引,并且驾驶员可以更加方便快捷地对注意力分散程度小的功能对应的控件进行操作。这既可以提高用户的使用体验,并且可以使得驾驶员能够投入足够的注意力在车辆驾驶上,提高车辆驾驶的安全性。
请参照图7,图7示例性示出了本申请实施例提供的一种应用控制方法的流程图。
如图7所示,该方法可包括步骤S711~S720。该方法可应用与车辆中的中控设备100。由前述图4所示的结构示意图可知,中控设备100可包括应用生命周期管理模块410、应用信息管理模块420、应用图标管理模块430、驾驶注意力要求等级(ARL)评估模块440以及驾驶信息收集模块450。
步骤S711~S713:ARL评估。
S711、ARL评估模块440可以向驾驶信息收集模块450发送驾驶信息获取请求。
ARL评估模块440可以周期性地获取驾驶信息并进行ARL评估。例如,ARL评估模块440可以每隔预设时间段向驾驶信息收集模块450请求获取驾驶信息,然后进行ARL评估。上述预设时间段可以是1分钟、2分钟等等。本申请实施例对上述预设时间段的长度不作限定。
可选的,ARL评估模块440也可以不定时获取驾驶信息并进行ARL评估。本申请实施例对ARL评估模块440进行两次ARL评估的间隔时间不作限定。
S712、驾驶信息收集模块450可以向ARL评估模块440发送驾驶信息。
响应于上述驾驶信息获取请求,驾驶信息收集模块450可以收集车辆的驾驶信息。其中,驾驶信息收集模块450可以向车辆200的行车记录仪26、传感器系统28、摄像系统29、自动驾驶系统31、行车模式管理系统32等部件获取驾驶信息。驾驶信息可以包括以下一项或多项:车速、行车模式、是否开启自动驾驶模式、自动驾驶模式的层级、道路类型(如城市道路、乡村山路、高度公路等)、道路的曲直程度、路上行人的数量、路上车辆的数量、道路的拥堵程度等等。本申请实施例对驾驶信息收集模块450向车辆的各个部件收集驾驶信息的具体方法不作限定。
驾驶信息收集模块450可以收集在接收到驾驶信息获取请求之前一段时间内车辆的驾驶信息。示例性的,驾驶信息收集模块450在时刻t1接收到驾驶信息获取请求。驾驶信息收集模块450可以收集时刻t1 之前的一段时间T1内车辆的驾驶信息。例如,车辆在T1时间段内的车速。本申请对上述T1的大小不作限定。可选的,驾驶信息收集模块450可以收集在接收到驾驶信息获取请求之后一段时间内车辆的驾驶信息。可选的,驾驶信息收集模块450也可以收集在接收到驾驶信息获取请求之前一段时间内车辆的驾驶信息,以及在接收到家还是信息获取请求之后一段时间内车辆的驾驶信息。示例性的,驾驶信息收集模块450在时刻t1接收到驾驶信息获取请求。驾驶信息收集模块450可以收集时间段T2内车辆的驾驶信息。上述时刻t1位于时间段T2内。本申请对上述T2的大小不作限定。
驾驶信息收集模块450可以将受到的驾驶信息发送给ARL评估模块440。
S713、ARL评估模块440可以根据驾驶信息进行驾驶注意力要求等级(ARL)评估,并检测到ARL变化。
ARL评估模块440根据驾驶信息进行ARL评估的方法可以参考前述实施例的介绍。这里不再赘述。ARL评估模块440可以将当前评估得到的ARL与之前评估得到的ARL进行比较,判断ARL是否变化。例如,ARL评估模块440可以将当前评估得到的ARL与上一次评估得到的ARL比较,判断当前评估得到的ARL在上一次评估得到的ARL的基础上是否增大。再例如,ARL评估模块440可以将当前评估得到的ARL与前多次评估得到的ARL比较。
S714、ARL评估模块440可以向应用生命周期管理模块410和应用图标管理模块430发送ARL变化通知,ARL变化通知包含当前评估得到的ARL。
当检测到ARL变化,ARL评估模块440可以向应用生命周期管理模块410和应用图标管理模块430发送ARL变化通知。
步骤S715~S717:停止运行确定出的需要停止运行的应用。
S715、应用生命周期管理模块410可以响应于ARL变化通知,向应用信息管理模块420请求获取当前运行的应用在运行阶段的注意力分散等级(ADL)。
S716、应用信息管理模块420可以向应用生命周期管理模块410发送当前运行的应用在运行阶段的ADL。
S717、应用生命周期管理模块410可以根据当前评估得到的ARL和应用在运行阶段的ADL,停止运行ADL高于ARL对应的ADL阈值的应用。
应用生命周期管理模块410可以根据预设的应用隐藏策略,确定哪些正在运行的应用是需要停止运行的,从而避免这些应用在运行的过程中过度分散驾驶员的注意力,使得驾驶员能在车辆驾驶上投入的注意力难以满足当前评估得到的ARL的要求。
在一种可能的实现方式中,应用生命周期管理模块410可以获取不同的ARL对应的ADL阈值。应用生命周期管理模块410可以判断哪些应用在运行阶段的ADL高于当前ARL对应的ADL阈值,并停止运行上述ADL高于当前ARL对应的ADL阈值。
可选的,应用生命周期管理模块410可以获取前述表1所示的应用隐藏策略表,并查表确定需要停止运行哪些应用。
上述运行的应用可以包括在中控设备100前台运行的应用、在中控设备100后台运行的应用。
这里对应用生命周期管理模块410停止运行应用的方法进行介绍。
在一种可能的实现方式中,中控设备100中正在运行的应用包括应用A。当判断出应用A在运行阶段的ADL高于当前ARL对应的ADL阈值,应用生命周期管理模块410可以关闭应用A,结束应用A的进程。这样,中控屏上不再显示应用A的用户界面。中控设备100的后台也不再运行应用A的进程。这可以避免应用A在运行阶段分散驾驶员的注意力,使得驾驶员能将更多的注意力投入车辆驾驶,从而提高驾驶安全。
在另一种可能的实现方式中,中控设备100中正在运行的应用包括应用A。当判断出应用A在运行阶段的ADL高于当前ARL对应的ADL阈值,应用生命周期管理模块410可以暂停运行应用A,保留后台中应用A的进程。也即是说,当暂停运行应用A,中控设备100可以在中控屏上取消显示应用A的用户界面,并中断应用A在运行过程中的所有任务。应用A不再对驾驶员产生吸引(如视觉吸引、听觉吸引等)。但应用A的进程仍可存在与中控设备100的后台。
其中,应用生命周期管理模块410可以存储在暂停运行应用A时,应用A的运行数据(如用户界面数据等),以便于后续恢复运行应用A。
进一步的,ARL评估模块440后续评估得到的ARL减小。当判断出应用A在运行阶段的ADL小于或等于后续评估得到的ADL对应ADL阈值,应用生命周期管理模块410可以根据应用A在暂停运行时的 运行数据,继续运行应用A。
示例性的,上述应用A为音乐应用。该音乐应用正在中控设备100中运行,播放音乐。当检测到音乐应用在运行阶段的ADL高于当前ARL对应的ADL阈值,应用生命周期管理模块410可以暂停运行音乐应用。上述暂停运行音乐应用可包括控制音乐应用暂停播放音乐。若在音乐应用运行过程中,中控屏上显示有音乐应用的用户界面,应用生命周期管理模块410暂停运行音乐应用还可包括在中控屏上关闭音乐应用的用户界面。可以看出,音乐应用暂停运行后可不再分散驾驶员的注意力。
其中,应用生命周期管理模块410可以存储音乐应用在暂停运行时,音乐应用播放音乐的数据以及显示的用户界面数据。当后续评估得到的ARL对应的ADL阈值再次大于音乐应用在运行阶段的ADL,应用生命周期管理模块410可以继续运行音乐应用。根据上述音乐应用在暂停运行时,音乐应用播放音乐的数据以及显示的用户界面数据,中控设备100可以从音乐应用上次暂停时音乐播放的位置处继续播放音乐,并显示音乐应用上次暂停时的用户界面。
步骤S718~S720:隐藏确定出的中控屏上需要隐藏的应用图标。
S718、应用图标管理模块430可以响应于ARL变化通知,向应用信息管理模块420请求获取应用在启动阶段的ADL。
S719、应用信息管理模块420可以向应用图标管理模块430发送应用在启动阶段的ADL。
S720、应用图标管理模块430可以根据当前评估得到的ARL和应用在启动阶段的ADL,隐藏ADL高于ARL对应的ADL阈值的应用的应用图标,显示ADL小于或等于ARL对应的ADL阈值的应用的应用图标。
应用图标管理模块430可以根据预设的应用隐藏策略,确定中控设备100中哪些应用的应用图标是需要隐藏的,从而避免驾驶员因操作这些应用图标而过度分散注意力,难以在车辆驾驶上投入满足当前评估得到的ARL要求的注意力。
在一种可能的实现方式中,应用图标管理模块430可以获取中控设备100中所有应用在启动阶段的ADL。当接收到ARL变化通知,应用图标管理模块430可以判断哪些应用在启动阶段的ADL高于ARL对应的ADL阈值。然后,应用图标管理模块430刷新中控屏上显示的桌面,隐藏ADL高于ARL对应的ADL阈值的应用的应用图标,显示ADL小于或等于ARL对应的ADL阈值的应用的应用图标。
在另一种可能的实现方式中,当ARL变化通知指示ARL增大时,应用图标管理模块430可以仅获取中控屏当前显示的应用图标对应的应用在启动阶段的ADL。然后,应用图标管理模块430可以判断这些应用在启动阶段的ADL是否高于ARL对应的ADL阈值,并隐藏ADL高于ARL对应的ADL阈值的应用的应用图标。可以理解的,ARL增大表示车辆驾驶对驾驶员的注意力要求提升,驾驶员在中控设备100的应用上投入的注意力应该减少。ARL增大后,ARL对应的ADL阈值减小。那么,相比于ARL增大前中控屏上显示的应用图标,中控设备100可以隐藏更多在启动阶段的ADL更小的应用的应用图标。
当ARL变化通知指示ARL减小时,应用图标管理模块430可以仅获取当前为显示在中控屏上的应用图标对应的应用在启动阶段的ADL。然后,应用图标管理模块430可以判断这些应用在启动阶段的ADL是否小于或等于ARL对应的ADL阈值,并恢复显示ADL小于或等于ADL对应的ADL阈值的应用的应用图标。可以理解的,ARL减小表示车辆驾驶对驾驶员的注意力要求降低,驾驶员可以投入更多的注意力在中控设备100的应用上。ARL减小后,ARL对应的ADL阈值增大。那么,相比于ARL减小前隐藏的应用图标,中控设备100可以恢复显示ADL小于或等于当前ARL对应的ADL阈值的应用的应用图标。
除了利用上述ARL对应的ADL阈值来判断需要隐藏的应用图标,应用图标管理模块430还可以根据前述表1所示的应用隐藏策略表来判断需要隐藏的应用图标。
由图7所示的方法可知,中控设备100可以实时检测车辆驾驶需要驾驶员投入注意力多少的变化。当检测到车辆驾驶需要驾驶员投入的注意力变化,中控设备100可以调整中控屏上显示的应用图标的数量,并且调整中控设备中正在运行的应用的数量。这可以避免驾驶员的注意力被中控设备上的应用过度分散,难以投入足够的注意力在车辆驾驶上,从而提高驾驶安全。并且,当根据车辆驾驶需要驾驶员投入的注意力变化判断出驾驶员能在分散出更多注意力在车辆驾驶以外的方面时,中控设备100可以恢复部分被隐藏的应用,减少隐藏应用对驾驶员使用中控设备的影响。
在一些实施例中,一个应用可以提供多项功能。这多项功能在启动阶段的ADL可能不同。这多项功能在运行阶段的ADL可能也不同。中控设备100可以根据预设的应用隐藏策略隐藏一个应用中的一项或多项功能。其中,当一个应用中的部分功能被隐藏,驾驶员仍能在继续使用这一个应用中其它未被隐藏的 功能。
示例性的,中控设备100可以显示正在运行的应用A的用户界面。该用户界面上可包含用于调用应用A提供的多项功能的控件。中控设备100可以判断应用A提供的多项功能控件在启动阶段的ADL是否高于当前ARL对应的ADL阈值。当一项功能在启动阶段的ADL高于当前ARL对应的ADL阈值,中控设备100可以隐藏上述用户界面上用于调用这一项功能的控件。
当应用A在运行过程中正在提供一项或多项功能,中控设备100可以判断这一项或多项功能在运行阶段的ADL是否高于当前ARL对应的ADL阈值。当一项功能在运行阶段的ADL高于当前ARL对应的ADL阈值,中控设备100可以停止运行应用A中这一项功能对应的程序。其中,应用A仍可继续提供其它在运行阶段的ADL不高于当前ARL对应的ADL阈值的功能。
例如,信息应用可提供发送语音消息的功能、编辑并发送文字消息的功能等功能。显然,驾驶员使用发送语音消息的功能需要投入的注意力少于使用编辑并发送文字消息的功能需要投入的注意力。当评估得到的ARL比较高,例如ARL为ARL4,中控设备100可以隐藏编辑并发送文字消息的功能,保留发送语音消息的功能。这样可以避免驾驶员使用编辑并发送文字消息的功能而过度分散注意力,难以将足够的注意力投入当前车辆驾驶上。但驾驶员仍能使用发送语音消息的功能。当评估得到的ARL较低,例如ARL为ARL0,中控设备100可以同时保留发送语音消息的功能、编辑并发送文字消息的功能。驾驶员既可以发送语音消息,也可以编辑文字发送文字消息。
再例如,导航应用可提供语音切换导航路线的功能和手动切换导航路线的功能等功能。显然,驾驶员使用语音切换导航路线的功能需要投入的注意力少于使用手动切换导航路线的功能需要投入的注意力。当评估得到的ARL较高,需要驾驶员在车辆驾驶上高度集中注意力,中控设备100可以同时隐藏语音切换导航路线的功能和手动切换导航路线的功能。这样可以避免驾驶员由于切换导航路线分散注意力,难以将足够的注意力投入当前车辆驾驶上。当评估得到的ARL为中等大小的ARL(如ARL为ARL3),需要驾驶员在车辆驾驶上投入中度注意力,中控设备100可以隐藏手动切换导航路线的功能,保留语音切换导航路线的功能。驾驶员不能使用手动切换导航路线的功能,但可以通过语音指示导航应用切换导航路线。当评估得到的ARL较小,仅需驾驶员在车辆驾驶上投入少量注意力,中控设备100可以同时保留语音切换导航路线的功能和手动切换导航路线的功能。驾驶员既可以语音切换导航路线,又可以手动切换导航路线。
由上述实施例可知,中控设备100可以单独隐藏一个应用提供的各项功能。一个应用中的一项功能被隐藏可以不影响这一个应用中其它功能的使用。中控设备100可以实时检测车辆驾驶需要驾驶员投入注意力多少的变化。当检测到应用中的一项功能的ADL会过度吸引驾驶员的注意力,使得驾驶员能在车辆驾驶上投入的注意力不能满足当前车辆驾驶的ARL的需求,则中控设备100可以将该应用的这一项功能隐藏。这可以避免驾驶员使用该应用的这一项功能而导致注意力被过度分散,从而提高驾驶安全。但驾驶员仍能继续使用该应用中其它未被隐藏的功能。上述方法可以在实现避免驾驶员因使用中控设备100上的应用而被过度分散注意力的基础上,减少隐藏应用对驾驶员使用中控设备100中应用的影响。
在一些实施例中,上述应用图标管理模块430可以根据当前评估得到的ARL和应用在启动阶段的ADL,确定是否调整应用图标在中控屏上的显示位置。例如,若当前评估得到的ARL比上一次评估得到的ARL大,应用图标管理模块430可以将更多ADL更大的应用的图标移动至中控屏上远离驾驶员一侧的区域,并将更多ADL更小的应用的图标移动至中控屏上靠近驾驶员一侧的区域。可选的,应用图标管理模块430可以向驾驶信息收集模块450获取驾驶信息。然后,应用图标管理模块430可以查询当前的驾驶信息对应的应用图标显示方式。应用图标管理模块430可以根据上述应用图标显示方式在中控屏上显示各个应用的图标。
可以看出,在本申请提供的应用控制方法中,中控设备100可以根据驾驶信息来控制中控设备100中的应用。上述控制中控设备100中的应用可以包括:控制应用在中控屏上的显示方式,控制应用的运行。上述控制应用在中控屏上的显示方式可包括:控制应用在中控屏上的显示位置,和/或,控制应用在中控屏上是否隐藏。通过上述方法,中控设备100可以实时根据驾驶信息的变化来调整应用在中控屏上的显示与运行,使得中控设备100当前显示以及运行的应用不会过多分散驾驶员的注意力,驾驶员能够在车辆驾驶上投入足够的注意力。上述方法可以有效提高驾驶安全。
在一些实施例中,当接收到启动应用的操作,中控设备100可以判断该应用在运行阶段的ADL是否高于当前ARL对应的ADL阈值。当判断出该应用在运行阶段的ADL高于当前ARL对应的ADL阈值,中控设备100可以拒绝运行该应用。
请参照图8,图8示例性示出了本申请实施例提供的一种应用控制方法的流程图。
如图8所示,该方法可包括步骤S811~S819。其中:
S811、应用生命周期管理模块410检测到启动应用A的操作1。
例如,上述操作1可是语音指令启动应用A的操作。本申请对上述操作1的具体方式不作限定。上述应用A仅为本申请的示例性说明。本申请对应用A的类型不作限定。
S812、响应于操作1,应用生命周期管理模块410可以向应用信息管理模块420请求获取应用A在运行阶段的ADL。
S813、应用信息管理模块420可以向应用生命周期管理模块410发送应用A在运行阶段的ADL。
S814、响应于操作1,应用生命周期管理模块410还可以向ARL评估模块440请求获取当前的ARL。
S815、ARL评估模块440可以向驾驶信息收集模块450发送驾驶信息获取请求。
S816、驾驶信息收集模块450可以向ARL评估模块440发送驾驶信息。
S817、ARL评估模块440可以根据驾驶信息进行驾驶注意力要求等级(ARL)评估,得到当前的ARL。
上述ARL评估模块获取驾驶信息并进行ARL评估的具体方法,以及驾驶信息收集模块450收集驾驶信息的具体方法均可以参考前述图7所示的方法的介绍。这里不再赘述。
S818、ARL评估模块440可以向应用生命周期管理模块410发送当前的ARL。
S819、应用生命周期管理模块410可以比较应用A在运行阶段的ADL与当前的ARL对应的ADL阈值,若ADL高于ADL阈值,则拒绝启动应用A,若ADL小于或等于ADL阈值,则启动应用A。
应用生命周期管理模块410可以根据应用A在运行阶段的ADL、当前的ARL以及应用隐藏策略来决定是否启动应用A。
在一种可能的实现方式中,应用生命周期管理模块410可以比较应用A在运行阶段的ADL与当前的ARL对应的ADL阈值。在应用A在运行阶段的ADL高于ADL阈值的情况下,应用生命周期管理模块410可以拒绝启动应用A。
可选的,应用生命周期管理模块410可以根据前述表1所示的应用隐藏策略表来决定是否启动应用A。当根据应用A在运行阶段的ADL、当前的ARL以及应用隐藏策略表确定出应用A需要隐藏,应用生命周期管理模块410可以拒绝启动应用A。否则,应用生命周期管理模块410可以启动应用A。
其中,在拒绝启动应用A的情况下,中控设备100可以提供拒绝启动提示,来提示驾驶员当前不宜启动应用A。例如,中控设备100可以语音提示“您当前需要集中注意力在车辆驾驶上,应用A启动后会过度分散您的注意力,不利于安全驾驶,因此不宜启动应用A”。本申请实施例对上述拒绝启动提示的具体方式不作限定。
在一些实施例中,若中控设备100在拒绝启动应用A之后的预设时间段内,再次接收到启动应用A的操作,中控设备100可以直接响应上述再次启动应用A的操作,启动应用A。也即是说,在用户多次要求启动应用A的情况下,即便应用A在运行阶段的ADL高于当前ARL对应的ADL阈值,中控设备100可以满足用户的要求,启动应用A。这可以避免在用户强烈要求启动应用A的情况下,中控设备100拒绝启动应用A影响用户使用中控设备100的体验。
需要进行说明的是,上述步骤S815~S817是可选的。在一种可能的实现方式中,当接收到应用生命周期管理模块410获取ARL的请求,ARL评估模块440可以将最近一次评估得到的ARL发送给应用生命周期管理模块410。
由图8所示的方法可知,中控设备100可以在接收到启动应用的操作时,判断应用启动后对驾驶员注意力的分散程度是否会超出驾驶员能从车辆驾驶上分散出来的注意力的最大值。在判断出应用启动后会过度分散注意力,导致驾驶员难以投入足够的注意力在车辆驾驶上的情况下,中控设备100可以拒绝启动该应用。这可以避免车辆驾驶过程中,驾驶员启动在运行阶段分散注意力程度较高的应用,从而使得驾驶员能有足够的注意力投入车辆驾驶,提高驾驶安全。
可以理解的,在本申请实施例中描述的各个用户界面仅为示例界面,并不对本申请方案构成限定。在其它实施例中,用户界面可以采用不同的界面布局,可以包括更多或更少的控件,可以增加或减少其它功能选项,只要基于本申请提供的同一发明思想,都在本申请保护范围内。
需要说明的是,在不产生矛盾或冲突的情况下,本申请任意实施例中的任意特征,或任意特征中的任意部分都可以组合,组合后的技术方案也在本申请实施例的范围内。
以上所述,以上实施例仅用以说明本申请的技术方案,而非对其限制;尽管参照前述实施例对本申请 进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
