Description

一种鸣笛方法及车载设备
本申请要求于2019年11月29日提交国家知识产权局、申请号为201911207322.2、发明名称为“一种鸣笛方法及车载设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及车联网无线通信技术领域，尤其涉及一种鸣笛方法及车载设备。
背景技术
随着汽车数量的增加，交通噪声引起的噪音问题日益突出。据调查机构指出，我国城市的环境噪声主要来自交通噪声，而汽车鸣笛产生的噪音是交通噪声的主要来源。从拥挤的城市干道，到优美的住宅小区，汽车鸣笛产生的噪音无处不在，不仅危害自身驾车安全，还危害他人休息和健康。
现有的车辆的鸣笛方式为：通过高功率的喇叭鸣笛。其中，小轿车的鸣笛音量一般在80分贝左右；而超过音量超过80分贝的声音会对人耳造成伤害，被认为是噪音，会产生较大的噪音污染。另外，对于隔音效果好的汽车，车内的驾驶员很难听到周围车辆的鸣笛，周围车辆的鸣笛不能对该驾驶员起到提示的效果。
综上所述，目前车辆所采用的鸣笛方案，可能并不能对周围车辆的驾驶员起到提示的效果，反而会对鸣笛车辆周围的人群产生较大的噪音伤害。
发明内容

可以理解的是，第二V2X报文是用于请求第三车载设备播放鸣笛提示的。因此，第三车载设备接收第二V2X报文之后，可以在第三车载设备所在车辆播放鸣笛提示，这样可以有效的提醒第三车载设备的驾驶员。
在一种可能的实施方式中，第二V2X报文请求中还包括第一车载设备所在车辆的位置信息；在第三车载设备根据第二V2X报文的目的地址，确定第三车载设备是接收所述第二V2X报文的目标设备之后，所述方法还包括：所述第三车载设备显示所述第 一车载设备所在车辆相对于第三车载设备所在车辆的位置。

具体实施方式
以下，术语“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。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请实施例中，V2X英文全称为vehicle to everything，中文解释为车辆与其他设备通信，也可以称为车用无线通信技术。V2X是将车辆与一切事物相连接的新一代信息通信技术。C-V2X是基于蜂窝技术的V2X，它是基于第三代合作伙伴项目(the 3rd generation partnership project，3GPP)全球统一标准的通信技术，或者说是基于3G/4G/5G等蜂窝网通信技术演进形成的车用无线通信技术。如，C-V2X可包含长期演进(long termevolution，LTE)-V2X和5G-V2X，从技术演进角度讲，LTE-V2X支持向5G-V2X平滑演进。本申请实施例提供的方法可适用于基于任何蜂窝(如3G/4G/5G，以及下一代的蜂窝网通信技术)技术的V2X。在另一些实施例中，本申请实施例提供的方法还可适用于基于无线保真(wireless fidelity，WIFI)，通用串行总线(universal serial bus，USB)等技术的V2X。
其中，V代表车辆，X代表任何与车辆交互信息的对象。当前X主要包含车辆、人(或说行人设备)、道路基础设备(或称为路侧单元，其是设置在路边可实现V2X通信，支持V2X应用的硬件单元)和网络。
V2X(或C-V2X)概述的信息交互可以包括：车辆与车辆之间(vehicle to vehicle，V2V)的交互、车辆与人之间(vehicle to pedestrian，V2P)的交互、车辆与路侧单元之间(vehicle to infrastructure，V2I)的交互、车辆与网络之间(vehicle to network，V2N)的交互。另外，C-V2X包含了两种通信接口:一种是车辆、人、道路基础设备之间的短距离直接通信接口(如PC5接口)，另一种是车辆和网络(如基站)之间的通信接口(如Uu接口)，可实现长距离和更大范围的可靠通信。
本申请实施例提供一种鸣笛方法，车载设备可以广播第一V2X报文，该第一V2X报文包括该车载设备的ID和该车载设备所在车辆的位置信息。当然，车载设备也可以接收到其他车载设备广播的第一V2X报文。例如，第一车载设备可以接收多个第二车载设备广播的多个第一V2X报文。然后，第一车载设备可以对比第一车载设备所在车辆的当前位置信息与多个第一V2X报文中的位置信息，从多个第二车载设备中确定出与第一车载设备所在车辆行驶方向相同，位于第一车载设备所在车辆的前方，且距离第一车载设备最近的N个第三车载设备；最后，响应于用户的鸣笛操作，第一车载设备可以向N个第三车载设备发送第二V2X报文，以请求N个第三车载设备播放鸣笛提示。
与常规方案相比，本申请实施例中，第一车载设备通过第二V2X报文请求其他车载设备播放鸣笛提示，而不是由第一车载设备所在车辆使用高频喇叭发出鸣笛。这样，可以减少对鸣笛车辆周围的人群产生噪音伤害，减少噪音污染。
并且，上述N个第三车载设备是与第一车载设备所在车辆行驶方向相同，位于第一车载设备所在车辆的前方，且距离第一车载设备最近的N个车载设备。即N个第三车载设备所在车辆是可能会影响第一车载设备所在车辆正常行驶的车辆。一般而言， 第一车载设备所在车辆发出的鸣笛提示都是为了提醒这些车辆注意避让。因此，本申请实施例中，第一车载设备针对性的向N个第三车载设备发送第二V2X报文，以请求N个第三车载设备播放鸣笛提示，可以减少对车辆周围的人群产生噪音伤害，减少噪音污染。
以下将结合附图，对本申请实施例中的技术方案进行描述。
请参考图1，为本申请实施例中的一种应用场景示意图。如图1所示，车辆1和车辆2都是行驶在第一方向(图示向右的方向)的车辆；车辆3、车辆4、车辆5和车辆6都是行驶在第二方向(图示向左的方向)的车辆。其中，每个车辆中都包括车载设备，且各个车辆中的车载设备可以进行V2X通信。例如，车辆1、车辆2、车辆3、车辆4、车辆5和车辆6的车载设备都可以广播第一V2X报文。以车辆5的车载设备广播的第一V2X报文为例，该第一V2X报文包括车辆5的车载设备的ID和车辆5的位置信息。车辆1、车辆2、车辆3、车辆4和车辆6中的车载设备可能都可以接收到车辆1广播的第一V2X报文。同理，车辆5中的车载设备也可以接收到其他车辆广播的第一V2X报文。
例如，以车辆5中的车载设备请求其他车辆中的车载设备播放鸣笛提示为例。假设车辆5的车载设备可以接收到车辆2、车辆3、车辆4和车辆6的车载设备广播的第一V2X报文。由于车辆5与车辆1距离较大，车辆5的车载设备无法接收到车辆1的车载设备广播的第一V2X报文。
车辆5中的车载设备可以接收用户的鸣笛操作。响应于该鸣笛操作，车辆5中的车载设备可以根据接收到的第一V2X报文(如车辆2、车辆3、车辆4和车辆6的车载设备广播的第一V2X报文)，以及车辆5所在位置，确定出与自身车辆5的行驶方向相同，位于车辆5的行驶方向的前方，且距离车辆5的车载设备最近的2个(即N＝2)第三车载设备对应的车辆为车辆4和车辆6。车辆5的车载设备可以向车辆4的车载设备和车辆6的车载设备发送第二V2X报文，以请求车辆4和车辆6的车载设备发出鸣笛提示。
示例性的，上述车辆(如车辆5)的车载设备可以在以下场景中，执行本申请实施例的方法，请求其他车辆中的车载设备播放鸣笛提示。
场景1：车辆5在禁止鸣笛的道路上行驶时。
可以理解，车辆5在禁止鸣笛的道路上行驶时，驾驶员不能通过控制车辆5鸣笛的方式，提醒周围的其他车辆注意避让。在这种情况下，执行本申请实施例的方法，不需要车辆5鸣笛，便可以达到提醒周围车辆注意避让的目的，满足在禁止鸣笛的道路上的行驶规范。
其中，各个道路的周围可以设置有道路基础设备，这些道路基础设备可以广播V2X报文(称为第三V2X报文)。该第三V2X报文中包括当前路段的道路信息。例如，该道路信息可以包括当前道路的位置、编号、道路类型(如国道、省道、市区道路或者县道等)、以及路段类型(如禁止鸣笛的路段、学校所在的路段、办公区所在的路段、住宅区所在的路段或者闹市区所在的路段等)。车辆5的车载设备可以接收上述第三V2X报文，根据第三V2X报文确定车辆5当前行驶在禁止鸣笛的道路上。
或者，车辆5的车载设备可以周期性获取车辆5的位置信息。例如，车辆5的车 载设备可以通过全球定位***(Global Positioning System，GPS)定位获取车辆5的位置信息。然后，车辆5的车载设备可以根据上述位置信息确定车辆5当前行驶在禁止鸣笛的道路上。
场景2：车辆5在闹市区的道路行驶时。
可以理解的是，车辆5在闹市区的道路上行驶时，如果驾驶员想要通过车辆5鸣笛的方式，提醒周围的其他车辆注意避让。闹市区较为喧哗，车辆5发出的鸣笛可能不会引起周围车辆的驾驶员的注意。在这种情况下，执行本申请实施例的方法，不需要车辆5鸣笛，也可以达到提醒周围车辆的驾驶员注意避让的目的。
其中，车辆5的车载设备可以接收上述第三V2X报文，根据第三V2X报文确定车辆5当前行驶在闹市区的道路上。或者，车辆5的车载设备可以根据车辆5的位置信息确定车辆5当前行驶在闹市区的道路上。
场景3：车辆5在学校、办公区、住宅区的道路上行驶时。
可以理解的是，车辆5行驶在学校的道路、办公区的道路或者住宅区的道路上时，车辆的鸣笛声产生的噪音会干扰到他人的学习、工作或休息。在这种情况下，执行本申请实施例的方法，不需要车辆5鸣笛，便可以达到提醒周围车辆注意避让的目的，且不会对周围的学校、办公区或住宅区的人群产生噪音伤害。
其中，车辆5的车载设备可以接收上述第三V2X报文，根据V2X报文确定车辆5当前行驶在学校的道路、办公区的道路或者住宅区的道路。或者，车辆5的车载设备可以根据车辆5的位置信息确定车辆5当前行驶在学校的道路、办公区的道路或者住宅区的道路。
场景4：车辆5在夜间(如晚上10：00-凌晨4:00的时间段)行驶在市区道路时。
可以理解的是，在夜间时间(如晚上10：00-凌晨4:00的时间段)，为人们休息的时间。市区道路两边可能是住宅小区，如果车辆5发出鸣笛，会影响市区居民的休息，对市区居民造成噪音伤害。在这种情况下，执行本申请实施例的方法，不需要车辆5鸣笛，便可以达到提醒周围车辆注意避让的目的。即使车辆5在夜间行驶在市区街道，也不会对市区道路边的住宅区内的居民造成噪音伤害。

可以理解的是，每个车辆的车载设备都可以广播第一V2X报文；但是，每个车载设备广播的第一V2X报文中包括的车载设备的ID和位置信息不同。例如，车辆1的车载设备广播的第一V2X报文中包括：车辆1的车载设备的ID和车辆1的位置信息；车辆3的车载设备广播的第一V2X报文中包括：车辆3的车载设备的ID和车辆3的位置信息。
虽然每个车辆的车载设备都可以广播第一V2X报文；但是，车辆5与不同车辆的 距离不同；因此，车辆5的车载设备可能只会接收到部分车载设备广播第一V2X报文。例如，由于图1所示的车辆1与车辆5之间的距离较大，导致车辆5的车载设备无法接收到车辆1的车载设备广播第一V2X报文。其他车辆(如车辆2、车辆3车辆4和车辆6)与车辆5之间的距离较小，车辆5可以接收到车辆2、车辆3车辆4和车辆6的车载设备广播第一V2X报文。本申请实施例的方法还包括S303。
S303：车辆5的车载设备接收到车辆2、车辆3、车辆4和车辆6广播的第一V2X报文。
其中，每个第一V2X报文包括对应车载设备的身份标识ID和所在车辆的位置信息。车辆5的车载设备在接收到多个第一V2X报文信息之后，可以存储接收到的第一V2X报文中的信息。
例如，表1为本申请实施例提供的一种第一车辆信息表的实例。如表1所示，第一车辆信息表中包括车辆5接收到的第一V2X报文中的ID和位置信息。
表1
Figure PCTCN2020124763-appb-000001
示例性的，第一V2X报文还可以包括车辆的方向信息。例如，车辆5的车载设备广播的第一V2X报文中还可以包括：车辆5的行驶方向，车辆5的行驶方向为第二方向(图示向左方向)。车辆2的车载设备广播的第一V2X报文中还可以包括：车辆2的行驶方向，车辆2的行驶方向为第一方向(图示向右方向)。例如，表1中所示的第一车辆信息表可以替换为表2所示的第一车辆信息表。
表2
Figure PCTCN2020124763-appb-000002
S304：车辆5的车载设备对比接收到的多个第一V2X报文中的位置信息以及车辆5的车载设备当前位置信息，确定出N个第三车载设备(车辆4和车辆6的车载设备)。
其中，第三车载设备所在车辆的行驶方向与第一车载设备所在车辆的行驶方向相同，位于第一车载设备所在车辆的行驶方向的前方，且第三车载设备是多个第二车载设备中，距离第一车载设备最近的车载设备。其中，第三车载设备的数量可以是一个、两个或三个等。
示例性的，如图1或表2所示，车辆5的行驶方向与车辆3、车辆4和车辆6的行驶方向相同。如图1所示，车辆3、车辆4和车辆6的行驶方向位于车辆5的前方。或者，根据表2所示的车辆3、车辆4和车辆6的位置信息，可以确定车辆3、车辆4和车辆6的行驶方向位于车辆5的前方。
假设N＝2，由图1或者表2所示的车辆3、车辆4和车辆6的位置信息，车辆5的车载设备可以确定，距离车辆5最近的2个第三车载设备对应的车辆为车辆4和车辆6。假设N＝3，由图1或者表2所示的车辆3、车辆4和车辆6的位置信息，车辆5的车载设备可以确定，距离车辆5最近的2个第三车载设备对应的车辆为车辆3、车辆4和车辆6。
以下实施例中以N＝2，上述N个第三车载设备对应的车辆为车辆4和车辆6为例，介绍本申请实施例的方法。
车辆5的车载设备中可以预设有第二车辆信息表。如表3所示，第二车辆信息表中包括上述N个第三车载设备的信息。
表3
Figure PCTCN2020124763-appb-000003
可以理解的是，车辆5的车载设备每次更新当前位置信息之后，可以对表4中的信息进行更新。或者，车辆5的车载设备检测到自身车辆的位置变化满足预设条件，对表4中的信息进行更新。
例如，预设条件是车辆1行驶过100米路程，或者，预设条件是时间经过5分钟等。即车辆5检测到自身车辆已行驶过100米路程，或者，车辆5确定距离上次更新表4的时间过去5分钟。车辆5获取自身的位置信息，并接收周围车辆广播的第一V2X报文。根据自身当前位置信息和第一V2X报文对车辆信息存储表中的车辆信息进行更新。
S305：响应于用户的鸣笛操作，车辆5的车载设备向车辆4和车辆6的车载设备发送第二V2X报文。
其中，车辆5的车载设备可以广播第二V2X报文。第二V2X报文用于请求车辆4和车辆6的车载设备播放鸣笛提示。该第二V2X报文中包括车辆4和车辆6的车载设备的ID。这样，车辆4和车辆6的车载设备接收到该第二V2X报文后，便可以播放鸣笛提示；而其他车辆(如车辆2或车辆3)的车载设备接收到该第二V2X报文，由于该第二V2X报文中不包括该车辆的车载设备的ID，因此可以丢弃该第二V2X报文。
例如，如表4所示，为本申请实施例提供的一种第二V2X报文的数据结构示意表：
表4
Figure PCTCN2020124763-appb-000004
示例性的，上述车辆4和车辆6的车载设备的ID可以作为第二V2X报文的目的地 址。车辆4和车辆6的车载设备的ID可以携带在表4所示的第二V2X报文的“目的地址”字段。
示例性的，车辆的车载设备上可以设置有鸣笛按键。上述鸣笛操作可以是用户对该鸣笛按键的点击操作。其中，上述鸣笛按键可以是物理按键或者车载设备的显示屏上的鸣笛选项。
或者，上述鸣笛操作可以是车载设备接收到用户的语音命令，该语音命令用于指示车辆鸣笛。例如，该语音命令可以为“鸣笛”。
S306：车辆4和车辆6的车载设备接收第二V2X报文，响应于第二V2X报文，车辆4和车辆6的车载设备播放鸣笛提示。
响应于用户的鸣笛操作，车辆5的车载设备请求车辆4和车辆6的车载设备播放鸣笛提示之后，车辆5的车载设备还可以判断车辆5当前行使的道路是否允许通过高频喇叭鸣笛。如果车辆5当前行使的道路允许通过高频喇叭鸣笛，车辆5则可以通过高频喇叭鸣笛。如果车辆5当前行使的道路不允许通过高频喇叭鸣笛，车辆5则不会通过高频喇叭鸣笛。
本申请实施例提供一种鸣笛方法，与常规方案相比，本申请实施例中，车辆5的车载设备通过第二V2X报文请求其他车载设备播放鸣笛提示，而不是由车辆5使用高频喇叭发出鸣笛。这样，可以减少对鸣笛车辆周围的人群产生噪音伤害，减少噪音污染。
并且，上述车辆4和车辆6是与车辆5的行驶方向相同，位于车辆5的前方，且距离车辆5最近的2个车辆。即车辆4和车辆6是可能会影响车辆5正常行驶的车辆。一般而言，车辆5发出的鸣笛提示都是为了提醒这些车辆注意避让。因此，本申请实施例中，车辆5的车载设备针对性的向车辆4和车辆6的车载设备发送第二V2X报文，以请求车辆4和车辆6的车载设备播放鸣笛提示，可以减少对车辆周围的人群产生噪音伤害，减少噪音污染。
在一种可能的实施方式中，车辆4的车载设备和车辆6的车载设备播放鸣笛提示之后，还可以在车载设备的显示屏上显示车辆5相对于自身车辆的位置。
例如，以车辆4的车载设备上的显示屏为例，车载设备显示器的显示界面如图4所示，车辆4与车辆5之间的距离为50米，车辆5位于车辆4的正后方，车辆4的显示屏包括车辆5和车辆4。
示例性的，上述S304可以包括S304a-S304d。例如，如图5所示，图3所示的S304可以包括S304a-S304d。
S304a：车辆5的车载设备根据当前位置确定车辆5的行驶方向。
需要说明的是，本申请实施例中的S304a-S304d是上述实施例中S304的具体实现，S304中的相关技术细节可以应用于本申请实施例中，为了减少重复，此处不再赘述。另外，本申请实施例中的方法也可以应用于上述S304中。
S304b：车辆5的车载设备根据多个第一V2X报文中的位置信息，确定出车辆2、车辆3、车辆4和车辆6的行驶方向。
例如，车辆5的车载设备可以根据第一V2X报文中的位置信息确定出该车载设备所在车辆的行驶方向。
又例如，车辆5的车载设备可以根据同一车载设备连续两个第一V2X中位置信息的变化，确定出该车载设备所在车辆的行驶方向。
S304c：车辆5的车载设备根据当前位置和多个第一V2X报文中的位置信息，分别计算每个车辆与车辆5之间的距离。
可以理解的是，通过执行步骤S304b，得到车辆2的行驶方向与车辆5的行驶方向相反，车辆3、车辆4和车辆6的行驶方向与车辆5的行驶方向相同。与车辆5的行驶方向相反的车辆不会影响车辆5的驾驶，且车辆2与车辆5不在同一侧道路。车辆5的车载设备可以计算与车辆5的行驶方向相同的车辆与车辆5之间的距离值。
其中，车辆5的车载设备可以根据第一V2X报文中的位置信息计算出车辆3与车辆5之间的距离。或者，车辆5的车载设备还可以通过距离传感器获取车辆3与车辆5之间的距离。
例如，车辆5计算得到车辆3与车辆5之间的距离为100米，车辆4与车辆之间的距离为50米，车辆6与车辆5之间的距离为50米。
S304d：车辆5从车辆2、车辆3、车辆4和车辆6中确定出与车辆5的行驶方向相同，在车辆5的行驶方向的前方，且距离车辆5的距离最近的车辆为车辆4和车辆6。
其中，如图1或表2所示，车辆5的行驶方向与车辆3、车辆4和车辆6的行驶方向相同。如图1所示，车辆3、车辆4和车辆6的行驶方向位于车辆5的前方。车辆5的车载设备根据车辆5与车辆3、车辆4和车辆6之间的距离确定车辆4和车辆6距离车辆5的距离最近。
采用本申请实施例中的方法，车辆5的车载设备可以逐步确定出与车辆5的行驶方向相同，在车辆5的行驶方向的前方，且距离车辆5的距离最近的车辆。使得车辆5可以有针对性的对周围车辆的驾驶员起到提示的效果，还可以减少对鸣笛车辆周围的人群产生噪音伤害，减少噪音污染。
本申请实施例还提供一种芯片***，如图6所示，该芯片***包括至少一个处理器601和至少一个接口电路602。处理器601和接口电路602可通过线路互联。例如，接口电路602可用于从其它装置(例如电子设备的存储器)接收信号。又例如，接口电路602可用于向其它装置(例如处理器601)发送信号。示例性的，接口电路602可读取存储器中存储的指令，并将该指令发送给处理器601。当所述指令被处理器601执行时，可使得电子设备执行上述实施例中的各个步骤。当然，该芯片***还可以包含其他分立器件，本申请实施例对此不作具体限定。
