Description

一种提示方法、装置及车辆 技术领域
本申请涉及智能驾驶技术领域，特别涉及一种提示方法、装置及车辆。
背景技术
随着智能驾驶技术的蓬勃发展，智能驾驶技术被广泛地应用于车辆。为了让用户获知车辆状态(例如，驾驶状态)，车辆配置了车载信息娱乐(in-vehicle infotainment，IVI)系统，并通过IVI系统输出用于提示车辆状态的提示信息。然而，在IVI系统处于高负载的情况下，IVI系统会出现提示信息输出卡顿或者提示信息无法输出的情况，导致用户无法及时获知车辆状态信息，从而会带来一定的安全隐患。
业界关于自动驾驶汽车提出了分级标准，国际自动机工程师学会(society of automotive engineers international，简称SAE International)提出的驾驶自动化分级标准包括L0-L5等六个级别。其中，对于驾驶自动化分级为L1-L2级的车辆，该车辆的驾驶员支持系统能够为驾驶员提供一些支持功能，其中，L1级的支持功能包括转向、制动或加速中的至少一项，L2级的支持功能包括转向、制动、加速、全速自适应巡航、主动车道保持、或限速识别中的至少一项。驾驶自动化分级为L3级的车辆可以实现半自动驾驶，该车辆的自动驾驶系统既能完成某些驾驶任务，也能在某些情况下监控驾驶环境，但驾驶员需要随时准备重新取得驾驶控制权，例如当车辆的驾驶状态由自动驾驶状态切换为待用户接管状态时，驾驶员必须驾驶车辆。因此，对于驾驶自动化分级为L1-L2级的车辆，在车辆出现转向、制动或加速中的任一情况时，若用户未能及时收到相应的提示信息或未收到提示信息，会导致用户的驾驶体验较差。对于驾驶自动化分级为L3级及以上的车辆，若车辆的驾驶状态从自动驾驶状态切换为请求用户接管状态时，若用户没有及时收到相应的提示信息或未收到提示信息，用户可能无法及时进行相应的处理，会导致车辆行驶存在安全隐患。
因此，如何确保将车辆状态即时、不中断地呈现给用户，以便用户及时了解并处理各种突发事件，进而提升用户的驾驶体验及车辆行驶的安全性，是本领域亟需解决的技术问题。
发明内容

具体实施方式
下面将结合附图，对本申请实施例进行详细描述。
本申请提供一种提示方法、装置以及车辆。其中，本申请中的提示装置可用于实现本申请实施例提供的提示方法。以及，在一些可能的实施例中，该提示方法可应用于车辆或车载部件或车载芯片。该方法包括：检测到第一事件，该第一事件包括用于指示车辆状态的事件；如果车载系统处于过载状态，控制第一装置输出第一提示信息，该第一提示信息用于向用户提示所述第一事件；其中，所述第一装置包括车载提示装置和/或非车载提示装置。在该方法中，若检测到用于指示车辆状态的第一事件，且车载系统处于过载状态时，可以控制第一装置输出用于提示第一事件的第一提示信息，便于用户及时获知第一事件并进行相应处理，有效提升用户的驾驶体验及车辆行驶的安全性。
可以理解的是，方法和装置是基于同一技术构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
业界关于自动驾驶汽车提出了分级标准，其中，国际自动机工程师学会(society of automotive engineers international，SAE International)提出的驾驶自动化分级标准包括L0-L5等六个级别。其中，对于驾驶自动化分级为L1-L2级的车辆，驾驶员支持系统能够为驾驶员提供一些支持功能，但是无论车辆的驾驶员支持功能是否已经开启，驾驶员都必须自己驾驶车辆，并且驾驶员需要时刻监督驾驶员支持系统提供的这些支持功能，以及驾驶员需要根据车辆的驾驶情况，控制车辆进行转向、制动、或加速中的任一项，以保证车辆行驶的安全。L0-L2级的支持功能的区别在于：L0级的支持功能仅限于提供警告和瞬时协助，L1级的支持功能为转向、制动或加速中的至少一项，L2级的支持功能为转向、制动、加速、全速自适应巡航、主动车道保持、或限速识别中的至少一项。驾驶自动化分级为L3级的车辆可以实现半自动驾驶，该车辆的自动驾驶系统既能完成某些驾驶任务，也能在某些情况下监控驾驶环境，但驾驶员需要随时准备重新取得驾驶控制权，例如当车辆的驾驶状态由自动驾驶状态切换为待用户接管状态时，驾驶员必须驾驶车辆。驾驶自动化分级为 L4级的车辆可以实现高度自动驾驶，该车辆的自动驾驶系统在某些环境和特定条件下，能够完成驾驶任务并监控驾驶环境。驾驶自动化分级为L5级的车辆可以实现完全自动驾驶，该车辆的自动驾驶系统在所有条件下都能完成的所有驾驶任务。
在一些实施例中，本申请实施例提供的方案用于提示车辆的路线规划信息或者告警信息时，则本申请实施例的方案可以适用于驾驶自动化分级为L0-L5级的车辆。在另一些实施例中，本申请实施例提供的方案用于提示车辆从自动驾驶状态切换为请求用户接管的状态时，则本申请实施例的方案可以适用于驾驶自动化分级为L2级及以上级别的车辆，后文不再赘述。
此外，应理解，本申请实施例的技术方案也可以应用其他需要输出提示信息的设备中，例如，飞行器、移动机器人等其他载具或交通工具，本申请实施例不作具体的限制。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)车载系统，是基于车身总线系统和互联网服务而形成的车载综合信息处理系统，也可以称作车载信息娱乐(in-vehicle infotainment，IVI)系统。IVI系统可以实现信息显示(例如，显示导航信息、实时路况、车辆状态等)、人机交互、辅助驾驶、故障检测、车身控制、无线通讯、或在线娱乐功能中的一项或多项应用，极大的提升了车辆的电子化、网络化和智能化水平。在一些可能的实施例中，IVI系统可以包括图像系统、语音系统、振动管理系统或灯光控制系统中的至少一种。在一些可能的实施例中，IVI系统可以用于输出与第一事件对应的第一提示信息。
2)第一事件，可以包括用于指示车辆状态的事件。在一些可能的实施例中，车辆状态可以包括车辆的驾驶状态，对于驾驶自动化分级标准为L3级及以上的车辆，上述驾驶状态可以包括自动驾驶状态、待用户接管状态或用户接管状态中的至少一种。其中，自动驾驶状态可以理解为车辆在智能驾驶系统的控制下，自动进行行驶的状态；待用户接管状态可以理解为当前车辆需要用户进行控制的状态；用户接管状态可以理解为车辆在智能驾驶系统和用户的控制下，进行行驶的状态。因此，第一事件例如可以是车辆的驾驶状态由自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆。
在另一些可能的实施例中，对于驾驶自动化分级为L0-L5级的车辆，第一事件可以是车辆与其当前行驶的道路中的故障物存在碰撞风险，需要提醒用户减速行驶。又例如，第一事件可以是车辆从高速下匝道，需要提示用户注意不要错过匝道口。
在另一些可能的实施例中，第一事件还可以包括用于指示车载系统的可靠性降低的事件。例如，第一事件可以是车载系统自身的提示功能失效，需要通过其他设备提醒用户车辆状态。
3)第一提示信息，可以理解为用于向用户提示第一事件的提示信息。应理解，第一提示信息可以包括但不限于图像信息、语音信息、振动信息或光电信息中的至少一种。其中，图像信息可以包括文字信息和/或图标信息，语音信息可以包括铃声信息和/或语音词条信息，振动信息可以包括振动组件的标识和振动频率，光电信息可以包括灯光信息。
4)过载状态，可以理解为IVI系统的内存资源或计算资源不足，或者IVI系统并行处理的任务较多，导致IVI系统负荷过高的状态。应理解，IVI系统处于过载状态时，会出现以下至少一种情况：显示图像卡顿、无法显示图像、播放语音卡顿、无法播出语音、无法输出振动信息、或者无法输出灯光信息。通过本申请实施例的提供的方法，即使IVI系 统处于过载状态，也可以即时、不中断地输出第一事件对应的第一提示信息，使得用户可以及时获知第一事件，从而有效提升用户的驾驶体验和车辆驾驶的安全性。
下面结合附图对本申请实施例适用的应用场景进行介绍。
图1A示出了本申请实施例适用的一种场景示意图。在该场景中，车辆100包括控制设备101、车载提示设备102和车载感知设备103。可以理解的是，控制设备101、车载提示设备102和车载感知设备103可以是车载系统的子部分。
需要说明的是，车辆100适用的电子电气架构(electrical/electronic architecture，EEA)可以是分布式ECU架构、域控制器EEA或中央集中式EEA中的任一种。控制设备101在不同电子电气架构中有不同的实现，下面针对不同的电子电气架构进行说明。
架构一、分布式ECU架构。
在分布式ECU架构中，车辆的每个功能由特定的电子控制单元(electronic control unit，ECU)进行控制；相应的，若车辆100的电子电气架构为分布式ECU架构，控制设备101可以为用于控制车载提示设备102的ECU。
架构二、域控制器EEA。
在域控制器EEA中，一些厂商基于不同的域划分对车载控制器的功能进行集成，进而将车载控制器划分为智能驾驶域控制器、动力域控制器、底盘域控制器、车身域控制器和座舱域控制器；另一些厂商将动力域、底盘域和车身域进一步融合为整车控制域，进而将车载控制器划分为整车域控制器、智能驾驶域控制器和智能座舱域控制器；以及，另一些厂商将智能座舱域与智能驾驶域融合，通过单颗车载芯片实现智能驾驶以及对智能座舱的控制。
其中，智能驾驶域控制器通常需要连接车载感知设备103，对车载感知设备103感知到的信息(例如路面信息)进行处理，进行目标定位、路径规划、决策控制、或无线通讯。动力域控制器可以为车辆提供动力来源，实现驱动车辆行驶的目的。底盘域控制器用于控制车辆的制动、转向、或悬架等功能。车身域控制器可以用于控制车头的部分(如前车指示灯)、车中间的部分(如车门、车窗等)和车尾部的部分(如后刹车灯、后位置灯、尾门锁、甚至双撑杆)。智能座舱域控制器可以用于控制与其关联的部件，其关联的部件例如可以是智能座椅、抬头显示(head up display，HUD)、仪表盘(cockpit)和IVI系统中的至少一项。整车域控制器可以采集加速踏板信号、制动踏板信号及其他部件信号，并做出相应判断后，进行驱动力矩控制、制动能量的优化控制、整车的能量管理、控制器局域网络(controller area network，CAN)的维护和管理、故障的诊断和处理、或车辆状态监视中的至少一项。
相应的，若车辆100的电子电气架构为域控制器EEA，控制设备101可以为智能座舱域控制器，或者控制设备101可以为车载芯片，该车载芯片集成了智能驾驶域控制器和智能座舱域控制器的功能。
架构三、中央集中式EEA。
在中央集中式EEA中，设置了车载计算平台，该车载计算平台可以实现对智能驾驶域、智能座舱域、车身域、动力域和底盘域的相关部件的控制。相应的，若车辆100的电子电气架构为中央集中式EEA，控制设备101可以为车载计算平台。
其中，车载提示设备102是用于输出提示信息的车载设备。例如，车载提示设备102 可以输出第一提示信息，该第一提示信息用于向用户提示第一事件。应理解，车载提示设备102可以是一个或多个车载设备，例如可以是车载音箱、车载显示屏(也称作“车载中控屏”)、车载提示灯、HUD、车载座椅、或方向盘中的至少一种。
其中，车载感知设备103可以用于获取车辆100当前行驶的道路的信息。道路的信息例如可以是道路参数、道路上的基建设施或道路上的障碍物对应的图像信息、道路上的障碍物与车辆100的距离信息、或者道路对应的天气信息中的至少一项。其中，车载感知设备103可以是摄像头、激光雷达、或毫米波雷达中的至少一项。
在一种可能的实施方式中，若控制设备101为集成了智能驾驶域控制器功能和智能座舱域控制器功能的车载芯片，车载感知设备103获取车辆100当前行驶的道路的信息，并将该道路的信息发送至控制设备101；进而控制设备101可以对该道路的信息进行处理，若控制设备101发现车辆100当前行驶道路中的障碍物与车辆100存在碰撞的风险，则控制设备101控制车辆100切换驾驶状态(例如从自动驾驶状态切换为待用户接管状态)。在控制设备101控制车辆100切换驾驶状态之后，控制设备101检测到车辆100的驾驶状态从自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆，即控制设备101检测到第一事件，此时如果车载系统处于过载状态，可以控制车载提示设备102输出第一提示信息，该第一提示信息用于向用户提示所述第一事件。例如，如图1B所示，车载提示设备102以车载中控屏为例，控制设备101可以控制车载中控屏显示第一提示信息“请接管”。如此，使得用户可以及时获知第一事件，便于用户进行相应的处理，从而有效提升用户的驾驶体验和用户用车的安全性。
在另一种可能的实施方式中，若控制设备101为智能座舱域控制器，车载感知设备103获取车辆100当前行驶的道路的信息，并将该道路的信息发送至智能驾驶域控制器；进而智能驾驶域控制器对该道路的信息进行处理，若智能驾驶域控制器发现车辆100当前行驶道路中的障碍物与车辆100存在碰撞的风险，则智能驾驶域控制器将车辆100的驾驶状态从自动驾驶状态切换为待用户接管状态。在智能驾驶域控制器控制车辆100切换驾驶状态之后，控制设备101检测到车辆100的驾驶状态从自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆，即控制设备101检测到第一事件，此时如果车载系统处于过载状态，可以控制车载提示设备102输出第一提示信息，该第一提示信息用于向用户提示所述第一事件。如此，使得用户可以及时获知第一事件，便于用户进行相应的处理，从而有效提升用户的驾驶体验和用户用车的安全性。
可选的，控制设备101检测到第一事件，此时如果车载系统处于过载状态，控制设备101还可以向至少一个设备200发送第一提示信息，进而可以通过至少一个设备200输出第一提示信息，有效提升用户获知第一事件的概率。其中，至少一个设备200是设置于车辆100之外的非车载提示装置(例如，手机、耳机、或可穿戴设备等中的至少一个)。
下面结合具体的附图对本申请实施例提供的技术方案进行说明。
请参见图2，图2示出了本申请实施例提供的一种提示方法的流程示意图，该方法可以应用于图1A所示的应用场景中。需要说明的是，在下文中，控制设备101是以集成了智能驾驶域控制器功能和智能座舱域控制器功能的车载芯片为例，对图2所示的技术方案进行描述。该方法包括：
S201、控制设备101检测到第一事件。
由前文的描述可知，第一事件，可以包括用于指示车辆状态的事件。
在一些可能的实施例中，上述车辆状态可以包括车辆的驾驶状态，对于驾驶自动化分级标准为L3级及以上的车辆，上述驾驶状态可以包括自动驾驶状态、待用户接管状态或用户接管状态中的至少一种。其中，自动驾驶状态可以理解为车辆在智能驾驶系统的控制下，自动进行行驶的状态；待用户接管状态可以理解为当前车辆需要用户进行控制的状态；用户接管状态可以理解为车辆在智能驾驶系统和用户的控制下，进行行驶的状态。因此，第一事件例如可以是车辆的驾驶状态由自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆。相应的，在该实施例中，车载感知设备103获取车辆100当前行驶的道路的信息，并将该道路的信息发送至控制设备101，控制设备101对该道路的信息进行处理，若控制设备101发现车辆100与该道路中的障碍物存在碰撞的风险，则控制设备101控制车辆100的驾驶状态由自动驾驶状态切换为待用户接管状态；控制设备101检测到车辆100的驾驶状态由自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆，即控制设备101检测到第一事件。
在另一些可能的实施例中，对于驾驶自动化分级为L0-L5级的车辆，第一事件可以是车辆与其当前行驶的道路中的故障物存在碰撞风险，需要提醒用户减速行驶。又例如，第一事件可以是车辆即将从高速下匝道，需要提示用户注意不要错过匝道口。相应的，在该实施例中，车载感知设备103获取车辆100当前行驶的道路的信息，并将该道路的信息发送至控制设备101，控制设备101对该道路的信息进行处理，控制设备101确定车辆100当前行驶的道路中的障碍物与车辆100存在碰撞的风险，需要提醒用户减速行驶，即控制设备101检测到第一事件。或者，车载感知设备103获取车辆100当前行驶的道路的信息，并将该道路的信息发送至控制设备101；控制设备101对该道路的信息进行处理，控制设备101确定车辆100即将从高速下匝道，需要提示用户注意不要错过匝道口，即控制设备101检测到第一事件。
在另一些可能的实施例中，第一事件还可以包括用于指示车载系统的可靠性降低的事件。例如，第一事件可以是车载系统自身的提示功能失效，需要通过其他设备提醒用户车辆状态。相应的，在该实施例中，控制设备101检测到车载系统的提示功能失效(例如，车载中控屏黑屏)，需要通过其他设备提醒用户车辆状态，即控制设备101检测到第一事件。
在一种可能的实施方式中，控制设备101检测到第一事件之后，控制设备101还可以获取车载系统的负载状态和/或第二事件对应的提示信息的输出情况，并根据车载系统的负载状态和/或第二事件对应的提示信息的输出情况，确定车载系统是否处于过载状态。
本申请实施例中，“第二事件对应的提示信息”可以理解车载系统当前待输出的提示信息。相应的，控制设备101可以根据第二事件对应的提示信息的输出时长和/或输出结果，来确定第二事件的提示信息的输出情况。
由前文描述可知，车载系统可以包括图像系统、语音系统、振动管理系统或灯光控制系统中的至少一种。以及，控制设备101是车载系统的子部分，且控制设备101可以是车载系统中的车载芯片。因此，控制设备101可以根据车载系统的车载芯片、图像系统(display sub system，DSS)、语音系统、振动管理系统、或灯光控制系统的资源使用率和/或调度情况，确定车载系统的负载状态。其中，车载芯片包括但不限于车载系统的中央处理器(central processing unit，CPU)、图像处理器(graphic processing unit，GPU)、现场可编程门阵列(field  programmable gate array，FPGA)、特殊应用集成电路(application specific integrated circuit，ASIC)、或片上系统(system on a chip，SoC)中的至少一种。
在一些可能的实施例中，控制设备101为车载系统中的车载芯片，控制设备101在检测到其自身的内存资源或计算资源的资源使用率大于90％，则确定车载系统处于过载状态。
在另一些可能的实施例中，车载系统包括图像系统和语音系统，控制设备101检测到图像系统和语音系统的内存资源或计算资源的资源使用率大于90％，则确定车载系统处于过载状态。
在另一些可能的实施例中，车载系统包括振动管理系统和灯光控制系统，控制设备101检测到振动管理系统关联的振动组件和/或灯光控制系统关联的灯光装置已被完全调度，则确定车载系统处于过载状态。
在另一些可能的实施例中，车载系统包括图像系统、语音系统、振动管理系统和灯光控制系统，若控制设备101检测到车载系统的图像系统和语音系统的内存资源或计算资源的资源使用率大于90％，以及检测到振动管理系统关联的振动组件和/或灯光控制系统关联的灯光装置已被完全调度，则确定车载系统处于过载状态。
在另一些可能的实施例中，控制设备101检测到车载系统输出第二事件的提示信息所用的时长大于第一预设时长，或者，控制设备101检测到车载系统在第二预设时长内未输出第二事件的提示信息，则确定车载系统处于过载状态。
在另一些可能的实施例中，控制设备101为车载系统中的车载芯片，控制设备101检测到其自身的内存资源或计算资源的资源使用率大于80％，以及控制设备101检测到车载系统在第二预设时长内未输出第二事件的提示信息，则确定车载系统处于过载状态。
S202、如果车载系统处于过载状态，控制设备101控制第一装置输出第一提示信息。
在本申请实施例中，第一提示信息用于向用户提示第一事件。可选的，第一提示信息可以包括但不限于图像信息、语音信息、振动信息或光电信息中的至少一种。其中，图像信息可以包括文字信息和/或图标信息，语音信息可以包括铃声信息和/或语言信息，振动信息可以包括振动组件的标识和振动频率，光电信息可以包括灯光信息。
在本申请实施例中，第一装置可以包括车载提示装置和/或非车载提示装置。请继续参见图1A，车载提示装置即图1A中的车载提示设备102，非车载提示装置即图1A中的至少一个设备200。关于车载提示设备102的具体实现，请参见前文的具体描述，这里不再赘述。至少一个设备200可以包括但不限于语音装置、光电装置、或显示装置中的至少一个。至少一个设备200例如可以是平板电脑、笔记本电脑、掌上电脑、耳机、音响、可穿戴设备(如智能手表，智能手环，计步器等)、虚拟现实(virtual reality，VR)设备、或手机中的至少一个。
由前文的描述可知，车载系统即IVI系统。相应的，“车载系统处于过载状态”可以理解为IVI系统的内存资源或计算资源不足或者IVI系统并行处理的任务较多导致其负载过高的状态。以及，IVI系统可以包括但不限于图像系统、语音系统、振动管理系统或灯光控制系统中的至少一种。相应的，IVI系统处于过载状态时，IVI系统的具体表现可以为以下至少一种情况：显示图像卡顿、无法显示图像、播放语音卡顿、无法播出语音、无法输出振动信息、或者无法输出灯光信息。
在一种可能的实施例中，若第一装置为HUD，在IVI系统的显示图像卡顿时，控制设备101确定IVI系统处于过载状态，则控制设备101控制HUD显示与第一事件相对应的 第一提示信息。
在另一种可能的实施例中，若第一装置为手机，在IVI系统无法播出语音时，控制设备101确定IVI系统处于过载状态，则控制设备101将与第一事件相对应的第一提示信息发送至手机，通过手机显示该第一提示信息。
在图2所示的技术方案中，控制设备101检测到第一事件，即使车载系统处于过载状态，仍然可以控制第一装置输出第一提示信息，以通过该第一提示信息向用户提示第一事件，使得用户可以即时、不中断地获知车辆状态并处理各种突发事件，从而有效提升用户的驾驶体验及车辆行驶的安全性。
需要说明的是，本申请实施例中，在车载系统处于过载状态时，控制设备101控制第一装置输出第一提示信息，包括但不限于以下实现情形：
情形一、车载系统的过载状态指示车载系统关联的第一交互子系统处于过载状态，控制设备101可以对该第一交互子系统的提示流程进行调整，基于调整后的提示流程控制第一装置输出第一提示信息。在情形一中，可以保证第一提示信息及时、不中断地被输出，便于用户获知第一事件。
其中，情形一包括但不限于以下实施例：
在一些可能的实施例中，第一交互子系统以车载系统中的语音系统为例，如果上述车载系统的过载状态指示语音系统停止播放语音或者播放语音卡顿，控制设备101可以控制第一装置输出与第一事件对应的第一语音信息(即第一提示信息)。其中，第一语音信息为预先存储的语音信息。因此，在语音系统停止播放语音或者播放语音卡顿时，通过控制第一装置将第一事件对应的预先存储的第一语音信息输出，省略了语音处理流程(例如语音解码、重采样、或混音等)，使得用户可以及时获知第一事件。
在一个可能的实施例中，第一语音信息预先存储在第一装置的内存中，且第一事件对应的第一语音信息可以包括语音词条信息和/或铃声信息。第一装置以车载音响为例，第一语音信息预先存储在车载音响的内存中，控制设备101检测到第一事件，可以控制车载音响直接从其内存中获取语音词条信息和/或铃声信息，并输出该语音词条信息和/或铃声信息。
在另一个可能的实施例中，第一语音信息预先存储于控制设备101中，且第一事件对应的第一语音信息可以包括语音词条信息和/或铃声信息。第一装置以车载音响为例，第一语音信息预先存储在控制设备101中，控制设备101检测到第一事件，向车载音响发送该语音信息词条和/或铃声信息，以使车载音响输出该语音词条信息和/或该铃声信息。
在另一些可能的实施例中，第一交互子系统以图像系统为例，如果上述车载系统的过载状态指示图像系统显示图像卡顿，控制设备101可以根据第一事件对应的候选图像所在的图层以及承载候选图像的背景图像所在的图层，控制第一装置输出第一提示信息。如此，在图像系统显示图像卡顿时，控制设备101可以根据第一事件对应的候选图像所在的图层以及承载候选图像的背景图像所在的图层，控制第一装置输出第一提示信息，使得第一提示信息可以正常输出，从而使得用户可以及时获知第一事件。
在本申请实施例中，“候选图像”可以理解为第一事件对应的第一提示信息对应的预设图像信息，“承载候选图像的背景图像”可以理解为图像系统在显示候选图像时所用的 背景图像。可选的，该候选图像可以是静态图像或者是动态图像。在一些可能的实施例中，该承载候选图像的背景图像可以是车辆的导航信息对应的图像信息或者默认的背景信息。以及，“图像系统显示图像卡顿”可以理解为图像系统显示一帧图像所用的时长大于第一预设时长。例如，第一预设时长以100ms为例，如果图像系统显示一帧图像所用的时长大于100ms，则认为图像系统显示图像卡顿。
需要说明的是，该背景图像可以与候选图像在不同图层或相同图层，以下对这两种情况分别进行介绍。
情况1，如果候选图像所在的图层和背景图像所在的图层为不同的图层，控制设备101可以调整该背景图像所在图层的参数，并控制第一装置基于调整后的参数在背景图像所在的图层显示背景图像，以及控制第一装置在候选图像所在的图层显示候选图像。如此，使得图像系统的内存资源紧张时，降低背景图像对内存资源的需求，从而使得图像系统具备足够的资源来确保第一事件对应的候选图像(即第一提示信息)可以被显示出来，从而使得用户可以及时获知第一事件。
可选的，控制设备101调整的背景图像所在图层的参数可以包括但不限于以下至少一项：绘制速率，显示速率或刷新频率。其中，该绘制速率是指控制设备101绘制背景图像所在的图层的速率；该显示速率是指控制设备101设定的图像系统显示背景图像所在的图层的速率(例如，该速率可以是图像系统在50ms内显示一次背景图像所在的图层)；该刷新频率是指背景图像所在的图层在预设时长内的刷新频率(例如，该刷新频率可以是图像系统在100ms内刷新2帧图像)。
在一个可能的实施例中，控制设备101调整的背景图像所在的图层的参数为第二图层的绘制速率。
如图3所示，上述候选图像所在的图层为第一图层，上述背景图像所在的图层为第二图层。以及，在图3中，图像系统在第一帧图像仅显示背景图像；图像系统在第二帧图像、第三帧图像和第四帧图像中，需显示背景图像和候选图像；且图像系统在显示第二帧图像和第三帧图像时显示卡顿，在显示第四帧图像时显示流畅。
图3中的(a)示出了第一图层和第二图层的绘制过程，如图3中的(a)所示，控制设备101通过降低第二图层的绘制速率，以及保持第一图层的绘制速率；进而在第一装置显示第二帧图像和第三帧图像时，控制设备101可以控制第一装置持续刷新候选图像(即候选图像分别刷新为“a”和“b”)，但不刷新背景图像(即背景图像保持为“1”)；以及，在第一装置显示第四帧图像时，控制设备101可以控制第一装置将候选图像刷新为“c”，以及将背景图像刷新为“2”。
相应的，图3中的(b)示出了第一图层和第二图层合成之后的显示效果，如图3中的(b)所示，在第一帧图像中仅显示背景图像；在第二帧图像、第三帧图像和第四帧图像中显示候选图像和用于承载候选图像的背景图像，且候选图像在第二帧图像、第三帧图像和第四帧图像中分别刷新为“a”、“b”和“c”，背景图像仅在第四帧图像中刷新为“2”。
如此，在图3中，控制设备101通过降低第二图层的绘制速率，以及保持第一图层的绘制速率，可以有效降低第二图层对内存资源的需求，使得图像系统有足够的内存资源可以保证第一图层可以正常绘制，从而使得在显示第二帧图像、第三帧图像和第四帧图像时，第一装置可以持续刷新候选图像，进而使得候选图像可以及时、不中断地呈现给用户，有助于用户及时、不中断地获知第一事件。
在另一个可能的实施例中，控制设备101调整的背景图像所在的图层的参数为该图层的刷新速率。
如图4所示，候选图像所在的图层为第一图层，背景图像所在的图层为第二图层。以及，在图4中，在第一帧图像中，图像系统仅显示背景图像；在第二帧图像、第三帧图像和第四帧图像中，图像系统需显示背景图像和候选图像；且图像系统在显示第二帧图像和第三帧图像时显示卡顿，在显示第四帧图像时显示流畅。
如图4所示，控制设备101通过降低第二图层的刷新频率，保持第一图层的刷新频率；进而在第一装置显示第二帧图像和第三帧图像时，控制设备101可以控制第一装置持续刷新候选图像(即候选图像分别刷新为“a”和“b”)，但不刷新背景图像(即背景图像保持为“1”)；以及，在第一装置显示第四帧图像时，控制设备101可以控制第一装置将候选图像刷新为“c”，以及将背景图像刷新为“2”。
如此，控制设备101通过降低第二图层的刷新频率，保持第一图层的刷新频率，可以有效降低第二图层对内存资源的需求，使得图像系统有足够的内存资源可以保证第一图层可以正常刷新，从而使得在显示第二帧图像、第三帧图像和第四帧图像时，第一装置可以持续刷新候选图像，进而使得候选图像可以及时、不中断地呈现给用户，有助于用户及时、不中断地获知第一事件。
情况2，如果上述候选图像和背景图像在同一个图层，控制设备101可以新建第三图层，并控制第一装置在第三图层显示候选图像。需要说明的是，由于候选图像和背景图像在同一个图层，导致该图层对内存资源的较高，而控制设备101新建的第三图层的对内存资源的需求较低，从而图像系统有足够资源可以正常绘制并显示第三图层，进而使得候选图像可以及时、不中断地呈现给用户，有助于用户及时、不中断地获知第一事件。
在一个可能的实施例中，若第一事件为车辆的驾驶状态从自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆。相应的，与第一事件对应的候选图像为“请接管”，承载候选图像的背景图像为道路信息，候选图像和背景图像均在同一个图层(即图5所示的第二图层)。
如图5所示，图像系统在显示第一帧图像和第二帧图像时显示卡顿，在显示第三帧图像时显示流畅，并且在第一帧图像中，候选图像和背景图像均在第二图层显示。因此，在显示第二帧图像时，控制设备101新建了第三图层，并控制第一装置在第三图层显示候选图像“请接管”，在第二图层显示未刷新的背景图像；以及，在显示第三帧图像时，控制设备101控制第一装置在第三图层显示候选图像“请接管”，在第二图层显示刷新后的背景图像。如此，候选图像“请接管”可以在第三图层及时地被显示出来，便于用户及时、不中断地获知第一事件。
进一步的，在一些可能的实施例中，控制设备101还可以调整第三图层的显示顺序(z-order)，以调整第三图层和第二图层的堆叠顺序，使得第三图层在图像的顶层显示，便于用户获知第一事件。
请参见图6，若第一事件为车辆的驾驶状态从自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆。与第一事件对应的候选图像为“请接管”，背景图像为道路信息；控制设备101控制第一装置在新建的第三图层(即虚线椭圆部分)显示候选图像“请接管”，以及在第二图层显示背景图像。在图6中的(a)中，第三图层的z-order的取值和第二图层的z-order的取值均为0；在图6中的(b)中，控制设备101将第三图层的z-order的取 值调整为1，第二图层的z-order的取值保持为0，使得在第三图层和第二图层之间的堆叠顺序中，第三图层的堆叠顺序为顶层，进而控制设备101可以控制第一装置在图像的顶层显示候选图像。
在另一些可能的实施例中，第一交互子系统以图像系统为例，如果上述车载系统的过载状态指示图像系统停止显示图像，控制设备101可以控制第一装置在第四图层显示第一事件对应的候选图像，其中，第四图层承载了候选图像的信息。应理解，第四图层可以是预先存储在第一装置或者控制设备101中的图层，也可以是控制设备101根据第一装置显示第一事件对应的历史提示信息生成的缓存图层。也就是说，在图像系统停止显示图像时，控制设备101可以控制第一装置直接输出预先存储的第四图层，减少了图像的绘制过程和合成过程，使得候选图像可以更快显示给用户，从而用户可以及时获知第一事件，并进行相应的处理。
在另一些可能的实施例中，第一交互子系统以振动组件为例，如果上述过载状态指示振动组件停止输出振动信息，控制设备101可以基于第一振动指令，控制第一装置输出与第一事件对应的第一振动信息，该第一振动指令为预先存储的振动指令。其中，车载系统中的振动管理系统用于生成振动组件的控制指令。因此，车载系统中的振动管理系统故障时，控制设备101可以向第一装置发送预先存储的第一振动指令，进而第一装置可以基于第一振动指令，输出第一振动信息。如此，即使车载系统中的振动管理系统故障，控制设备101仍然可以控制第一装置输出第一振动信息，从而使得用户可以及时获知第一事件。在一些可能的实施例中，第一装置可以为车载座椅或方向盘。
情形二、车载系统的过载状态指示车载系统关联的第一交互子系统处于过载状态，控制设备101可以控制第一装置以车载系统关联的第二交互子系统对应的提示方式输出第一提示信息。在情形二中，可以使得第一提示信息被正常输出，有效提升用户获知第一事件的概率。
其中，情形二包括但不限于以下实施例：
在一些可能的实施例中，第一交互子系统以语音系统为例，如果过载状态指示语音系统停止播放语音或者播放语音卡顿，控制设备101可以控制第一装置以车载系统关联的第二交互子系统对应的提示方式输出第一提示信息。第二交互子系统是车载系统中除语音系统之外的其他交互系统。在一些可能的实施例中，第二交互子系统可以包括但不限于振动组件、图像系统、或灯光装置中的至少一项。相应的，第二交互子系统对应的提示方式包括振动提示方式、图像提示方式、或光电提示方式中的至少一种，第一提示信息包括第二振动信息、第二图像信息或第二光电信息中的至少一种。
在另一些可能的实施例中，第一交互子系统以图像系统为例，如果上述车载系统的过载状态指示图像系统显示图像卡顿或停止显示图像，控制设备101可以控制第一装置以车载系统关联的第二交互子系统对应的提示方式输出第一提示信息。其中，第二交互子系统是车载系统中除图像系统之外的其他交互系统。在一些可能的实施例中，第二交互子系统包括但不限于振动组件、语音系统、或灯光装置中的至少一项。相应的，第二交互子系统对应的提示方式包括振动提示方式、语音提示方式、或光电提示方式中的至少一种，第一 提示信息可以包括但不限于第二振动信息、第二语音信息或第二光电信息中的至少一种。
可以理解的是，光电信息可以是灯光信息，不同的第一事件可以对应不同颜色的灯光信息。例如，若第一事件为车辆的驾驶状态由自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆，第一装置为车载提示灯，控制设备101可以控制车载提示灯显示绿色灯光。又例如，若第一事件为车辆与其当前行驶的道路中的故障物存在碰撞风险，需要提醒用户减速行驶，控制设备101可以控制车载提示灯显示黄色灯光。
在另一些可能的实施例中，第一交互子系统以振动组件为例。如果所述过载状态指示车载系统停止输出振动信息，即第一交互子系统(振动组件)处于过载状态，控制设备101控制第一装置以车载系统关联的第二交互子系统对应的提示方式输出第一提示信息。其中，第二交互子系统是车载系统中除振动组件之外的其他交互系统。在一些可能的实施例中，第二交互子系统可以包括但不限于图像系统、语音系统、或灯光装置中的至少一项。相应的，相应的，第二交互子系统对应的提示方式包括图像提示方式、语音提示方式、或光电提示方式中的至少一种，第一提示信息可以包括但不限于第二图像信息、第二语音信息或第二光电信息中的至少一种。
情形三、车载系统关联的所有交互系统均处于过载状态，可以向非车载提示装置发送第一提示信息，通过非车载提示装置输出第一提示信息。在情形三中，可以保证第一提示信息及时地被输出，有效提升用户获知第一事件的概率。
其中，非车载提示装置可以包括但不限于平板电脑、笔记本电脑、掌上电脑、耳机、音响、可穿戴设备(如智能手表，智能手环，计步器等)、虚拟现实(virtual reality，VR)设备、或手机中的至少一个。
其中，情形三包括但不限于以下实施例：
在一些可能的实施例中，若第一事件为车辆的驾驶状态从自动驾驶状态切换为待用户接管状态，需提醒用户接管车辆，非车载提示装置为手机。控制设备101检测到车辆的驾驶状态从自动驾驶状态切换为待用户接管状态，可以向手机发送第一提示信息，通过手机显示该第一提示信息，进而提醒用户接管车辆。因此，若用户在低头玩手机，用户通过手机可以及时获知第一事件，并进行相应的操作。
在另一些可能的实施例中，若第一事件为车辆的驾驶状态从自动驾驶状态切换为待用户接管状态，需提醒用户接管车辆，非车载提示装置为手机和智能手表，与第一事件对应的第一提示信息包括图像信息和振动信息。控制设备101检测到第一事件时，控制设备101可以向手机发送该图像信息，以及向智能手表发送振动控制指令，从而手机可以显示该图像信息，智能手表可以基于该振动指令，输出该振动信息。如此，通过多个设备向用户输出第一提示信息，便于用户获知第一事件。
在一种可能的实施方式中，如果车载系统处于过载状态，控制设备101可以根据第一事件和映射关系确定一个或多个提示方式，根据车载系统当前的过载状态，从一个或多个提示方式中确定第一提示方式，并控制第一装置输出第一提示方式对应的第一提示信息。如此，使得第一事件的提示方式与车载系统的负载状态相符合，从而使得第一提示信息可以及时输出，便于用户获知第一事件。
其中，该映射关系是第一事件与预设提示方式之间的对应关系。请参见表1，表1示 出了该映射关系的一种示例。在表1中，若第一事件为车辆的驾驶状态由自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆，则第一事件对应的预设提示方式为语音提示方式、图像提示方式和振动提示方式；若第一事件为车辆与其当前行驶的道路中的故障物存在碰撞风险，需要提醒用户减速行驶，则第一事件对应的预设提示方式为语音提示方式和图像提示方式；若第一事件为车载系统自身的提示功能失效，需要通过其他设备提醒用户车辆状态对应的提示信息，第一事件对应的预设提示方式为语音提示方式和图像提示方式。

请参见图7，在图7中，第一事件对应的预设提示方式包括图像提示方式、语音提示方式和振动提示方式。图7还示出了每种提示方式对应的详细信息。
其中，图像提示方式对应的详细信息包括图像原始信息、图像数据描述、图像数据和其他图像信息。图像原始信息用于描述第一事件，图像原始信息可以包括但不限于图片的数量、大小、位置、布局、或资源索引ID(即第一事件对应的候选图像的链接地址)中的至少一项。图像数据描述用于描述第一事件对应的候选图像所在的图层，该图像数据描述可以包括候选图像所在的图层对应的尺寸信息、归属信息、Z-Order信息、内存地址、或物理存储位置中的至少一项。图像数据是预先绘制或合成的图层数据，可以通过显示设备直接进行显示，无需进行绘制处理或合成处理。可选的，图像数据是可以动态更新的。其他图像信息可以包括候选图像的显示方式和/或显示设备标识。
其中，语音提示方式对应的详细信息包括语音原始信息、语音数据描述、语音数据、和其他语音信息。语音原始信息用于描述第一事件，语音原始信息可以包括但不限于第一事件对应的音频资源文件和/或音频资源文件的链接地址。语音数据描述用于描述与第一事件对应的第一语音信息，语音数据描述可以包括但不限于第一语音信息的类型、大小、地址、或存储位置中的至少一项。语音数据是经过预处理(例如，音频解码、重采样、混音、后处理等)的语音数据，可以通过语音设备(例如，扬声器或车载音响)直接进行播放。其他语音信息可以包括但不限于第一语音信息的播放方式和/或语音设备标识。其中，语音播放的方式例如可以包括播放次数和/或播放周期。
其中，振动提示方式对应的详细信息包括振动组件ID和振动描述。其中，振动组件ID可以指示用于提示第一事件的振动组件。振动描述用于描述相关振动组件的振动频率和/或振动时间。
需要说明的是，第一事件可以对应至少一种提示方式，相应的，第一提示信息可以对 应多种表现形式。请参见图8，图8示出了第一事件集合与第一提示信息集合的示意图。若第一事件为车辆与其当前行驶的道路中的故障物存在碰撞风险，需要提醒用户减速行驶，第一事件对应的提示方式包括图像提示方式和语音提示方式；相应的，第一事件对应的第一提示信息可以包括减速标志和减速提示音。若第一事件为车辆从高速下匝道，需要提示用户注意不要错过匝道口，第一事件对应的提示方式包括图像提示方式和语音提示方式；相应的，第一事件对应的第一提示信息可以包括换道图标和换道提示音。若第一事件为车辆的驾驶状态由自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆，第一事件对应的提示方式包括图像提示方式、语音提示方式和振动提示方式；相应的，第一事件对应的第一提示信息可以包括告警图标、方向盘图标、接管提示音、以及振动提醒。
在本申请实施例中，控制设备101根据映射关系，确定出的一个或多个提示方式可以包括图像提示方式、语音提示方式、振动提示方式、或光电提示方式中的至少一种。以及，第一提示方式可以包括一个或多个提示方式。
在一些可能的实施例中，若控制设备101根据上述映射关系确定出的第一事件对应的提示方式包括语音提示方式和图像提示方式，车载系统当前的过载状态指示车载系统显示图像卡顿，则控制设备101将语音提示方式确定为第一提示方式，控制设备101控制第一装置以语义提示方式输出第一事件对应的语音信息。
在另一些可能的实施例中，若控制设备101根据上述映射关系确定出的第一事件对应的提示方式为语音提示方式、图像提示方式和振动提示方式，车载系统当前的过载状态指示车载系统的显示功能故障，则控制设备101将语音提示方式和振动提示方式确定为第一提示方式，控制设备101控制第一装置以语义提示方式输出第一事件对应的语音信息，以及控制第一装置以振动提示方式输出第一事件对应的振动信息。
进一步的，控制设备101还可以获取第一事件的历史提示方式，并基于历史提示方式，对上述映射关系进行更新。在一些可能的实施例中，历史提示方式可以是图像提示方式，且在该图像提示方式对应的图像信息包括图形标识，而现有的映射关系中的图像提示方式仅包括文字标识，控制设备101通过对映射关系进行更新，使得更新后的映射关系中的图像提示方式对应的提示信息包括图形标识和文字标识。如此，使得该映射关系更加完善，进而使得该映射关系的应用更广泛。可选的，控制设备101可以通过深度学习等技术，实现对映射关系的更新。
以上对于图2所示的实施例的技术方案的描述，是以控制设备101为集成了智能驾驶域控制器和智能座舱域控制器的功能的车载芯片为例。为了便于理解，下面控制设备101以智能座舱域控制器为例，进一步对本申请提供的技术方案进行说明。
图9示出了本申请实施例适用的另一种可能的场景的示意图。若第一事件为车辆的驾驶状态由自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆。在图10中，智能驾驶域控制器可以用于对车载感知设备103采集到的信息进行处理，根据处理结果决策将车辆的驾驶状态由自动驾驶状态调整为待用户接管状态。在智能驾驶域控制器在对车辆的状态进行调整之后，智能座舱域控制器检测到车辆的驾驶状态由自动驾驶状态切换为待用户接管状态，需要提醒用户接管车辆，即智能座舱域控制器检测到第一事件。智能座舱域控制器还可根据预设的映射关系，确定出第一事件对应的一个或多个提示方式，并进一步对其自身的负载状态进行监控和分析，以及结合IVI系统的过载状态从该对应的一个或 多个提示方式筛选出第一提示方式，该第一提示方式包括图像提示方式、语音提示方式或振动提示方式。
进一步的，图10示出了与第一事件的提示方式相关的细节信息。如图10所示，智能座舱域控制器检测到第一事件之后，智能座舱域控制器可以根据预设的映射关系，查询出第一事件对应的信息标记，该信息标记可以指示一个或多个提示方式。或者，智能座舱域控制器根据预设的映射关系，无法查询出第一事件对应的提示方式，智能座舱域控制器可以在当前映射关系中建立与第一事件对应的预设提示方式。或者，智能座舱域控制器可以对预设的映射关系中与第一事件对应的提示方式进行更新。
由图10可知，若上述信息标记指示第一事件对应的提示方式为图像提示方式时，第一事件存在对应的候选图像，以及用于承载该候选图像的背景图像，且候选图像和背景图像在不同的图层。智能座舱域控制器可以结合IVI系统的过载状态，调整该背景图像所在的图层的参数(例如降低绘制速率或刷新速率)，使得图像系统有足够的内存资源来保证候选图像可以被正常绘制或正常刷新。或者，智能座舱域控制器可以通过预先存储的图层(即缓存图层)显示第一事件对应的候选图像。
以及，若上述信息标记指示第一事件对应的提示方式为语音提示方式时，智能座舱域控制器可以控制语音设备输出第一事件对应的预先存储的语音信息。
以及，若上述信息标记指示第一事件对应的提示方式为振动提示方式时，智能座舱域控制器可以基于预先存储的振动指令，控制振动组件输出第一事件对应的振动信息。
