第二告警模块,设置为根据所述异常信息输出告警信息。
第五方面,本发明实施例还提供了一种计算机可读存储介质,存储有计算机可执行指令,所述计算机可执行指令用于上述第一方面的车辆预警的方法。
第六方面,本发明实施例还提供了一种计算机可读存储介质,存储有计算机可执行指令,所述计算机可执行指令用于执行上述第二方面的车辆预警的方法。
与现有技术相比,本发明实施例包括:获取车辆的实时信息,确定所述车辆出现异常;将所述车辆的异常信息通过短距离无线通讯的方式发送至附近的终端。在本发明实施例中,采用短距离无线通讯的方式,便捷快速,成本低,推广型强,可以不依赖于3G/4G或者GPS;通过Wi-Fi Direct或蓝牙扩展的控制位进行通信,可以在建立局域网过程中将车辆的异常信息发送出去,进一步提高了信息传播的速度;通过ODB(On Board Diagnostics,车载自动诊断系统)或者其他诊断接口,获取车辆的实时信息,监测准确,及时;基于车辆上终端即可实现智能互联驾驶辅助,不需要额外的成本。
本发明的其它特征和优点将在随后的说明书中阐述,并且,部分地从说明书中变得显而易见,或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
附图用来提供对本发明技术方案的进一步理解,并且构成说明书的一部分,与本申请的实施例一起用于解释本发明的技术方案,并不构成对本发明技术方案的限制。
图1为本发明实施例的车辆预警的方法流程图(发送端);
图2为本发明实施例扩展帧结构的示意图;
图3为本发明实施例的车辆预警的方法的整体流程图;
图4本发明实施例的车辆预警的方法流程图(接收端);

具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白,下文中将结合附图对本发明的实施例进行详细说明。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任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
现在的智能驾驶辅助方案在应用到山区,或者隧道等网络覆盖不到区域,监测的难度就会明显增大,效果也会大打折扣。即使有网络3G/4G网络的时延也难以满足实时监测的要求。另外,如果只通过监测位置与速度,很难准确判断车辆的实际运行情况,从而很难预判或者及时告警周围车辆。
为了至少解决上述技术问题,本发明实施例提供了以下技术方案:
如图1所示,针对发送端,本发明实施例的车辆预警的方法,包括:
步骤101,获取车辆的实时信息,确定所述车辆出现异常;
步骤102,将所述车辆的异常信息通过短距离无线通讯的方式发送至附近的终端。
在本发明实施例中,采用短距离无线通讯的方式,便捷快速,成本低,推广型强,可以不依赖于3G/4G或者GPS。

通过车载控制与诊断系统可获得车辆的速度、加速度、发动机转速、发动机工作状态、变速箱工作状态等信息。
其中,所述传感器可包括如下至少之一:
加速度传感器、重力传感器、光线传感器、红外传感器、陀螺仪。
通过车辆上的终端的传感器,可获得车辆的速度、加速度等信息。

为了记录详尽的车辆行驶状态与轨迹,可以在利用短距离无线通讯 (无线局域网)同时,结合GPS,以及3G/4G/5G网络使用,形成多网络覆盖与组合,协同工作。
在一实施方式中,所述车辆的实时信息包括如下至少之一:
车辆速度、车辆加速度、发动机转速、发动机工作状态、变速箱工作状态、车辆位置信息。
在一实施方式中,所述获取车辆的实时信息,确定所述车辆出现异常包括:
根据所述车辆的实时信息,判断是否满足预设条件,满足预设条件时,确定所述车辆出现异常。
在一实施方式中,所述预设条件包括如下至少之一:
所述车辆出现故障;
所述车辆的速度在指定时间内的速度减少量大于速度变化阈值;
所述车辆的负向加速度大于加速度阈值。
其中,上述预设条件可以是指车辆出现故障、车辆交通事故或者车辆紧急刹车等情况。
车辆出现故障可包括发动机、变速箱等车辆中的部件出现问题。
如果车辆的行驶速度,在短时间内急剧降低,说明可能发生碰撞或者在紧急踩刹车,或者负向加速度急剧增大,说明车辆在紧急刹车,可以通过车辆的速度在指定时间内的速度减少量大于速度变化阈值,或者所述车辆的负向加速度大于加速度阈值来判断。
当满足预设条件,则触发了某种类型的紧急事件,立刻通过短距离无线通讯的方式通知附近的终端,通过终端的显示机制或者音频系统或其他必要措施,提示驾驶员采取必要的应对措施。
所述异常信息可以是指示车辆某个部件出现故障、或者出现事故、或者出现紧急刹车等的信息。
在一实施方式中,所述将所述车辆的异常信息通过短距离无线通讯的 方式发送至附近的终端包括如下至少之一:
通过短距离无线通讯的方式与附近的终端组建无线局域网,在组建局域网过程中,将所述车辆的异常信息发送至所述终端;

在一实施方式中,所述短距离无线通讯包括如下至少之一:Wi-Fi Direct(无线保真直连)、蓝牙。
现在的Wi-Fi Direct或者蓝牙,当发射功率达到最大的时,覆盖组网范围可以达到最大覆盖范围例如几百米甚至几千米,意味着在此范围左右的终端,可以组成网络,在发生紧急事故时,可以及时提醒后车与对向车道的车,前方有事故发生。避免更大的损失与伤亡。
在一实施方式中,所述短距离无线通讯为Wi-Fi Direct时,所述方法还包括如下至少之一:
在探测请求Probe Request帧的帧体信息元素的对等网络P2P属性信息字段区,增加终端告警业务信息属性项;
在探测响应Probe Response帧的帧体信息元素的P2P属性信息字段区,增加终端告警业务信息属性项。
在一实施方式中,所述在组建局域网过程中,将所述车辆的异常信息发送至所述无线局域网内的终端,包括:
在Wi-Fi Direct的设备发现阶段,将所述车辆的异常信息携带在所述终端告警业务信息属性项中,发送至所述无线局域网内的终端。
在一实施方式中,所述将所述车辆的异常信息携带在所述终端告警业务信息属性项中,包括:
将所述车辆的异常信息转换为终端业务告警信息编码,携带在所述终端告警业务信息属性项中。
所述短距离无线通讯为Wi-Fi Direct时,运行于智能终端中的软件系 统,首先会使Wi-Fi Direct处于Scan(扫描)模式,并进行全信道扫描。之后,Find(发现)又分为Search(搜索)和Listen(监听)两个阶段,这两个阶段交叉执行。Search阶段和Scan类似,区别在于Search只扫描1、6、11三个信道,并且对接收到的Probe Response和Beacon(信标)帧要判断是否包含P2P IE。Listen阶段随机在1、6、11三个信道监听,响应包含P2P IE的Probe Request。Listen的时间为n个100TU(time unit,时间单元),802.11规定1TU=1024微秒,约1毫秒,n是一个随机整数,所以Listen持续的时间约为100毫秒的整数倍。这里随机数的目的是让双方都能发现对方,否则如果双方刚好同时处于Search和Listen状态,那么永远也扫描不到对方,而随机数的出现总能让双方快速发现对方。
为了便于快速建立无线局域网络。本发明实施例提出在Wi-Fi Direct的设备发现阶段,扩充Probe Request帧或Probe Response帧结构,在帧体信息元素的P2P属性信息中增加终端业务告警信息属性,使得完成Wi-Fi Direct设备发现时,也获得了Wi-Fi Direct终端具有的基本通信业务性能;当Wi-Fi Direct设备连接后,用户可以根据解析和保存的终端业务告警信息,方便的对已连接的终端进行信息交换。
在本发明实施例中,在Wi-Fi Direct帧的信息元素(P2P IE)的属性值(Attribute ID)中,对标准协议保留值进行重新定义,保留值110表示终端的业务性能属性,同时定义了具体的终端告警业务编码,作为P2P属性信息字段区的扩充项。
如图2所示,对Wi-Fi Direct设备发现过程使用的Probe Request帧和Probe Response帧,Frame Body(帧体)部分的信息元素进行扩充和改造,在标准中定义帧体P2P IE信息的基础上增加定义的终端告警信息。
在一实施方式中,所述短距离无线通讯为蓝牙时,所述方法还包括:
在探测信息帧的帧体信息元素的属性信息字段区,增加终端告警业务信息属性项。
在一实施方式中,所述在组建局域网过程中,将所述车辆的异常信息 发送至所述无线局域网内的终端,包括:
在蓝牙的设备发现阶段,将所述车辆的异常信息携带在所述终端告警业务信息属性项中,发送至所述无线局域网内的终端。
在一实施方式中,所述将所述车辆的异常信息携带在所述终端告警业务信息属性项中,包括:
将所述车辆的异常信息转换为终端业务告警信息编码,携带在所述终端告警业务信息属性项中。
所述短距离无线通讯为蓝牙时,运行于智能终端中的软件系统,基于蓝牙协议的设备的进行信息交互与组网时,使蓝牙处于扫描模式,并进行信道扫描。之后,又分为搜索和监听两个阶段,两个阶段交叉执行。若某一蓝牙设备正在进行广播,则它不会响应当前正在进行的设备扫描,而同时允许正在进行广播的设备连接到正在扫描的设备上,从而有效避免了重复扫描,而通过对连接机制的改善,蓝牙设备连接建立过程可以明显减少信息传递的过程时间。从而在蓝牙射频能覆盖到的范围内的设备,能迅速的发现对方并通过保留字段的码字进行告警信息交互。同时使蓝牙能以应用程序迅速启动连接器,并以数毫秒的传输速度完成经认可的数据传递后并立即关闭连接,而传统蓝牙协议下即使只是建立链路层连接都需要花费100ms,建立L2CAP(Logical Link Control and Adaptation Protocol,逻辑链路控制与适应协议)层的连接建立时间则更长。
为了便于快速建立无线局域网络。本发明实施例提出在蓝牙的设备发现阶段,扩充探测信息帧的帧结构,在帧体信息元素的属性信息中增加终端告警业务性能信息属性,使得完成蓝牙设备发现时,也获得了蓝牙终端具有的业务性能;当蓝牙设备连接后,用户可以根据解析和保存的终端告警业务性能信息,方便的对已连接的终端进行信息交换或互联控制。
本发明实施例中,通过Wi-Fi Direct或蓝牙扩展的控制位进行通信,可以在建立局域网过程中将车辆的异常信息发送出去,进一步提高了信息传播的速度。
在一实施方式中,所述将所述车辆的异常信息通过短距离无线通讯的方式发送至附近的终端包括:
通过终端的外置射频信号放大设备或车载的射频信号放大设备,发送所述车辆的异常信息。
可以同时配备智能终端的外置射频信号放大设备,或者配合车载的射频信号放大装置,以扩大无线局域网覆盖范围。
在一实施方式中,所述组建无线局域网包括:
通过鉴权与授权的方式对局域网中的终端进行绑定。
在一实施方式中,所述将所述车辆的异常信息通过短距离无线通讯的方式发送至附近的终端包括:

在一实施方式中,所述方法还包括:
根据所述异常信息输出告警信息。
此处输出告警信息是指除了通知接收端(附近终端),还对本端进行告警,以便驾驶员及时采取措施。
在一实施方式中,所述根据所述异常信息输出告警信息包括如下至少之一:
根据所述异常信息输出视频的告警信息;
根据所述异常信息输出音频的告警信息。
其中,所述视频的告警信息可以包括:显示告警的提示框、播放告警的动画视频等。
其中,所述音频的告警信息可以是播放语音提示告警信息、播放指定的告警声音等。
上述实施例中,基于智能终端支持的Wi-Fi Direct协议或者蓝牙协议,在不需要GPS或者3G/4G网络覆盖的情况下,由多个智能终端链接组成无线局域网,同时智能终端运行的软件系统,通过车载的ODB接口,或者车载ECU,或者车载微机系统等其他控制与诊断系统,实时获取车辆的发动机运行信息,车辆速度,以及其他车辆传感器信息,并结合获取到的其他车辆的同类信息,实时处理以上信息,判断车辆的运行状态,在紧急状态下,及时通知无线局域网内的其他车辆,并警告驾驶员,避免连环事故,或者其他形式的人员财产损失。
以下结合上述车辆预警的方法流程,对发送端这侧的流程进行整体的大致说明,如图3所示,主要包括以下步骤:
步骤601:通过车载控制与诊断系统、车辆上终端的传感器、GPS、无线网络获取车辆的实时信息,并根据获取到的实时信息确定所述车辆出现异常;
步骤602:通过加密的方式将所述车辆的异常信息通过短距离无线通讯的方式发送至附近的终端;
步骤603:根据所述异常信息输出告警信息。
针对上述步骤601,在一个可选的实施例中,可以通过以下方式实现:根据所述车辆的实时信息,判断是否满足预设条件,满足预设条件时,确定所述车辆出现异常。
针对上述步骤602,在一个可选的实施例中,可以通过以下方式实现:

步骤404,当帧的信息解析完成后,在终端上对终端告警业务性能信息进行保存,存储时,终端地址,终端名称和终端业务告警信息编码建立关联关系;同时在终端上显示发现的设备时,显示关联的终端业务告警信息。
步骤405,对已发现的Wi-Fi Direct终端设备,用户进行连接后,通过查询已连接终端关联的告警业务性能,若连接的终端无关联的告警业务性能,即为普通Wi-Fi Direct终端设备;若连接的终端已有关联的告警业务性能,就可以进行信息交换并告警与广播。

步骤504,当帧的信息解析完成后,在终端上对终端业务性能信息进行保存,存储时,终端地址,终端名称和终端告警业务性能编码建立关联关系;同时在终端上显示发现的设备时,显示关联的告警业务性能信息。
步骤505,对已发现的蓝牙设备,用户进行连接后,通过查询已连接终端关联的告警业务性能,若连接的终端无关联的告警业务性能,即为普通蓝牙终端设备;若连接的终端已有关联的告警业务性能,就可以进行告警信息交换或连接控制。
