本发明目的的实现、功能特点及优点将结合实施例,参照附图做进一步说明。
具体实施方式
应当理解,此处所描述的具体实施例仅用以解释本发明,并不用于限定本发明。
参照图1,图1为本发明前车路况显示系统第一实施例的功能模块示意图。
为实现将前车的前方路况信息显示给后车,因此,本实施例中,前车路况显示系统包括:若干第一车载单元10、若干第二车载单元20。
如图2所示,第一车载单元10安装在第一车辆上,第二车载单元20安装在第二车辆上,而第二车辆位于第一车辆的后方。同时,第一车载单元10与第二车载单元20可以进行无线通信,比如采用微波通信方式进行数据传输。
本实施例中,具体由第一车载单元10通过车载终端实时采集第一车辆的安全信息,并将安全信息发送给路边单元,其中,车载终端至少包括车载摄像头,安全信息至少包括车载摄像头采集的第一车辆前方的路况视频图像;
其中,车辆上的车载终端除了车载摄像头,还可以包括各种传感终端,比如胎压传感器、GPS传感器等,因此,对应的安全信息除了车载摄像头采集的车辆前方的路况视频图像之外,还可以包括通过胎压传感器采集的车辆胎压、通过GPS传感器采集的车辆实时地理位置等。
本实施例中,第二车载单元20在与第一车载单元10建立通信连接时,获取第一车载单元10通过车载终端所采集的安全信息,并在第二车辆上至少显示路况视频图像,比如在车辆的中控屏幕或内后视镜上显示路况视频图像等。
随着智能交通的发展,车辆以及交通设备都会变得越来越智能化,比如车辆会集成有更多的智能终端及通信功能,从而可实现车辆与车辆之间的通信,进而使得后方车辆也能实时了解前车前方的路况信息。
此外,还需要说明的是,对于道路上行驶的车辆来说,该车辆是前车还是后车具体根据当前所处环境而定,也即前车与后车实质为一种相对概念,例如,道路上行驶有A、B、C三辆车,A在B的前方、B在C的前方,因此,对于A、B来说,A是前车、B是后车;而对于B、C来说,则B是前车、C是后车。因此,对于A、B来说,B车辆上安装的车载单元具有第二车载单元的功能,而对于B、C来说,B车辆上安装的车载单元具有第一车载单元的功能。
本实施例中,通过车辆中的车载单元完成对车辆的安全信息采集并与其他车辆上的车载单元建立通信连接,从而将本车的车载单元所采集的安全信息转发给后车的车载单元,进而使得后车在跟车的过程中也能实时掌握前车的前方路况,进而提升车辆的行车安全。
进一步可选的,在本发明前车路况显示系统一实施例中,第二车载单元20还用于:获取第一车辆的标识信息,并将该标识信息发送给第一车载单元10进行验证;当该标识信息验证通过时,与第一车载单元10建立通信连接并接收第一车载单元10所返回的安全信息。
本实施例中并不限定车辆的标识信息的具体形式,本实施例中优选标识信息为车牌号码。
本实施例中为避免非相关车辆也获取到本车的安全信息,因此,需要对外部车辆的接入请求进行验证,比如确定外部车辆是否位于本车的后面等。例如,后车获取前车的车牌号码并发送给前车进行验证,若前车接收到的后车发送的车牌号码与前车自身车牌号码相同,则可确定验证通过,也即可认为后车当前正处于前车的后方,因此,前车可以将通过自身前置摄像头所拍摄的前方路况视频图像发送给后方车辆,进而使得后方车辆驾驶员能够实时清楚了解前车的前方路况以避免由于视线阻挡而发生意外事故。
参照图3,图3为本发明前车路况显示系统第二实施例的功能模块示意图。基于上述实施例,本实施例中,前车路况显示系统还包括:路况监控平台40,路况监控平台30与第一车载单元10、第二车载单元20进行通信,比如通过移动通信网络进行无线通信。
本实施例中,路况监控平台30接收所述第一车载单元10所上传的所述安全信息,根据所述安全信息进行路况模拟,得到模拟结果,并根据所述模拟结果,向所述第一车载单元10发送相应提醒信息,其中,所述安全信息至少还包括车辆的速度信息、GPS信息。
例如,路况监控平台30可以对某一路段内的所有车辆进行实时监控,具体根据接收到的由第一车载单元10上传的车辆安全信息,进行路况模拟,比如模拟各车辆的行驶速度、方向及实时位置变化等,同时判断当前路况模拟是否正常,比如各车辆的行驶状态是否正常、车辆是否会发生碰撞事故等,进而得到相应模拟结果,并根据模拟结果,向第一车载单元10发送相应提醒信息,比如提醒驾驶员当前超速、提醒驾驶员前方有车辆请勿超车等。
进一步可选的,在本发明前车路况显示系统一实施例中,路况监控平台30还用于:在所述第一车载单元10与所述第二车载单元20不在通信范围内时,将所述第一车载单元10上传的所述安全信息转发给所述第二车载单元20,以供在所述第二车辆上至少显示所述安全信息中的所述路况视频图像。
如图4所示,第一车载单元10与第二车载单元20不在有效通信范围内,但二者都与路况监控平台30进行通信。本实施例中可以解决前后两辆车不在通信范围内时这一特殊场景下如何进行安全信息传输的问题。
例如,第一车载单元10实时将采集到的前方路况视频图像上传路况监控平台30,当第一车载单元10与第二车载单元20之间连接断开或不在有效通信范围之内使,路况监控平台30将会将接收到的第一车载单元10实时上传的前方路况视频图像转发给第二车载单元20,进而使得后车驾驶员能够实时了解前车的前方车况。
参照图5,图5为本发明前车路况显示方法第一实施例的流程示意图。本实施例中,前车路况显示方法包括:
步骤S110,第一车载单元通过车载终端实时采集第一车辆的安全信息,其中,所述车载终端至少包括车载摄像头,所述安全信息至少包括所述车载摄像头采集的所述第一车辆前方的路况视频图像;
步骤S120,第二车载单元在与所述第一车载单元建立通信连接时,获取所述第一车载单元通过所述车载终端所采集的所述安全信息,并在第二车辆上至少显示所述路况视频图像。
本实施例中,具体由第一车载单元10通过车载终端实时采集第一车辆的安全信息,并将安全信息发送给路边单元,其中,车载终端至少包括车载摄像头,安全信息至少包括车载摄像头采集的第一车辆前方的路况视频图像;
其中,车辆上的车载终端除了车载摄像头,还可以包括各种传感终端,比如胎压传感器、GPS传感器等,因此,对应的安全信息除了车载摄像头采集的车辆前方的路况视频图像之外,还可以包括通过胎压传感器采集的车辆胎压、通过GPS传感器采集的车辆实时地理位置等。
本实施例中,第二车载单元20在与第一车载单元10建立通信连接时,获取第一车载单元10通过车载终端所采集的安全信息,并在第二车辆上至少显示路况视频图像,比如在车辆的中控屏幕或内后视镜上显示路况视频图像等。
随着智能交通的发展,车辆以及交通设备都会变得越来越智能化,比如车辆会集成有更多的智能终端及通信功能,从而可实现车辆与车辆之间的通信,进而使得后方车辆也能实时了解前车前方的路况信息。
此外,还需要说明的是,对于道路上行驶的车辆来说,该车辆是前车还是后车具体根据当前所处环境而定,也即前车与后车实质为一种相对概念,例如,道路上行驶有A、B、C三辆车,A在B的前方、B在C的前方,因此,对于A、B来说,A是前车、B是后车;而对于B、C来说,则B是前车、C是后车。因此,对于A、B来说,B车辆上安装的车载单元具有第二车载单元的功能,而对于B、C来说,B车辆上安装的车载单元具有第一车载单元的功能。
本实施例中,通过车辆中的车载单元完成对车辆的安全信息采集并与其他车辆上的车载单元建立通信连接,从而将本车的车载单元所采集的安全信息转发给后车的车载单元,进而使得后车在跟车的过程中也能实时掌握前车的前方路况,进而提升车辆的行车安全。
参照图6,图6为图5中步骤S120的细化流程示意图。基于上述实施例,本实施例中,上述步骤S120包括:
步骤S1201,所述第二车载单元获取所述第一车辆的标识信息,并将所述标识信息发送给所述第一车载单元进行验证;
步骤S1202,当所述标识信息验证通过时,所述第二车载单元与所述第一车载单元建立通信连接以接收所述第一车载单元所返回的所述安全信息,并在所述第二车辆上至少显示所述安全信息中的所述路况视频图像。
本实施例中并不限定车辆的标识信息的具体形式,本实施例中优选标识信息为车牌号码。
本实施例中为避免非相关车辆也获取到本车的安全信息,因此,需要对外部车辆的接入请求进行验证,比如确定外部车辆是否位于本车的后面等。例如,后车获取前车的车牌号码并发送给前车进行验证,若前车接收到的后车发送的车牌号码与前车自身车牌号码相同,则可确定验证通过,也即可认为后车当前正处于前车的后方,因此,前车可以将通过自身前置摄像头所拍摄的前方路况视频图像发送给后方车辆,进而使得后方车辆驾驶员能够实时清楚了解前车的前方路况以避免由于视线阻挡而发生意外事故。
参照图7,图7为本发明前车路况显示方法第二实施例的流程示意图。本实施例中,前车路况显示方法包括:
步骤S210,所述第一车载单元将通过所述车载终端所采集的所述安全信息上传路况监控平台;
步骤S220所述路况监控平台接收所述第一车载单元所上传的所述安全信息,根据所述安全信息进行路况模拟,得到模拟结果,并根据所述模拟结果,向所述第一车载单元发送相应提醒信息,其中,所述安全信息至少还包括车辆的速度信息、GPS信息。
本实施例中,路况监控平台30接收所述第一车载单元10所上传的所述安全信息,根据所述安全信息进行路况模拟,得到模拟结果,并根据所述模拟结果,向所述第一车载单元10发送相应提醒信息,其中,所述安全信息至少还包括车辆的速度信息、GPS信息。
例如,路况监控平台30可以对某一路段内的所有车辆进行实时监控,具体根据接收到的由第一车载单元10上传的车辆安全信息,进行路况模拟,比如模拟各车辆的行驶速度、方向及实时位置变化等,同时判断当前路况模拟是否正常,比如各车辆的行驶状态是否正常、车辆是否会发生碰撞事故等,进而得到相应模拟结果,并根据模拟结果,向第一车载单元10发送相应提醒信息,比如提醒驾驶员当前超速、提醒驾驶员前方有车辆请勿超车等。
进一步可选的,在本发明前车路况显示方法一实施例中,所述前车路况显示方法还包括:在所述第一车载单元与所述第二车载单元不在通信范围内时,所述路况监控平台将所述第一车载单元上传的所述安全信息转发给所述第二车载单元,以供在所述第二车辆上至少显示所述安全信息中的所述路况视频图像。
如图4所示,第一车载单元10与第二车载单元20不在有效通信范围内,但二者都与路况监控平台30进行通信。本实施例中可以解决前后两辆车不在通信范围内时这一特殊场景下如何进行安全信息传输的问题。
例如,第一车载单元10实时将采集到的前方路况视频图像上传路况监控平台30,当第一车载单元10与第二车载单元20之间连接断开或不在有效通信范围之内使,路况监控平台30将会将接收到的第一车载单元10实时上传的前方路况视频图像转发给第二车载单元20,进而使得后车驾驶员能够实时了解前车的前方车况。
以上仅为本发明的优选实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
