图2是本发明实施例一提供的车辆客户端的结构框图;
图3是本发明实施例二提供的驾驶行为指引信息的生成装置的结构框图。
本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
在本发明实施例中,车辆客户端获取到车辆运行信息、车辆位置信息及路边。
以下结合具体实施例对本发明的实现进行详细描述:
实施例一
图1示出了本发明实施例一提供的驾驶行为指引信息的生成方法的实现流程,该方法运行在包括车辆客户端、服务器和车辆驾驶者指定的客户端的驾驶行为指引信息的生成系统中,下面以服务器侧为例来进行说明,详述如下:
在步骤S101中,接收车辆客户端发送的车辆运行信息、车辆位置信息以及路面状况信息。
在本发明实施例中,车辆上安装有车辆客户端,通过该车辆客户端可以获取车辆运行信息、车辆位置信息以及路面状况信息,并发送所述车辆运行信息、所述车辆位置信息以及所述路面状况信息至服务器。
具体的,车辆客户端2如图2所示,包括:车辆运行信息获取模块21、GPS模块22、重力传感器23和信息发送模块24。
其中,车辆运行信息获取模块,与车辆的车载自动诊断系统(On Board Diagnostics,OBD)连接,用于获取车辆运行信息,所述车辆运行信息包括当前车速、当前发送机转速、当前方向盘转向角、当前各个轮胎的转速、档位和刹车等信息;
GPS模块22,用于获取车辆位置信息;
重力传感器23,用于获取路面状况信息,所述路面状况信息包括路面的坡度信息、路面的急转弯信息、路面是否平整等;
信息发送模块24,用于发送所述车辆运行信息、所述车辆位置信息以及所述路面状况信息至所述服务器。
其中,车辆运行信息获取模块包括控制器局域网络总线(Controller Area Network, CAN)子模块和诊断子模块。CAN总线子模块和诊断子模块通过连接车辆上的OBD系统,监控车辆的CAN网络数据,进而获得车辆的当前车速、当前发送机转速、当前方向盘转向角和当前各个轮胎的转速等车辆运行信息。
其中,OBD系统能在车辆运行过程中实时监测车辆的发动机电控系统及车辆的其它功能模块的工作状况,如有发现工况异常,则根据特定的算法判断出具体的故障,并以诊断故障代码(Diagnostic Trouble Codes,DTC)的形式存储在系统内的存储器上。OBD系统自诊断后得到的有用信息可以为车辆的维修和保养提供帮助,维修人员可以利用车辆原厂专用仪器读取故障码,从而可以对故障进行快速定位,以便于对车辆的修理,减少人工诊断的时间。
CAN总线是由研发和生产汽车电子产品著称的德国BOSCH公司开发的,并最终成为国际标准(ISO11898)。是国际上应用最广泛的现场总线之一。 在北美和西欧,CAN总线协议已经成为汽车计算机控制系统和嵌入式工业控制局域网的标准总线,并且拥有以CAN为底层协议专为大型货车和重工机械车辆设计的J1939协议。近年来,CAN总线所具有的高可靠性和良好的错误检测能力受到重视,被广泛应用于汽车计算机控制系统和环境温度恶劣、电磁辐射强和振动大的工业环境。
具体的,信息发送模块24是一个3G模块,通过该3G模块可以发送车辆运行信息、车辆位置信息以及路面状况信息至服务器。
另外,该车辆客户端2还包括钥匙门开关ACC点火检测模块,该模块用于获取车辆的发动机信息。启动该模块后,车辆客户端2中的其它模块可以开始工作。
在步骤S102中,根据所述车辆运行信息、车辆位置信息以及路面状况信息生成驾驶行为指引信息。
在本发明实施例中,服务器可以根据接收到的车辆运行信息、车辆位置信息以及路面状况信息生成相应的驾驶行为指引信息。
比如,当车辆运行信息中包括当前车速、当前方向盘转向角和当前轮胎的转速时,根据所述车辆运行信息、车辆位置信息以及路面状况信息可以生成指引车辆驾驶者限速行驶或者指引车辆驾驶者立刻对车辆的轮胎充气的驾驶行为指引信息。
具体包括以下步骤:
步骤1、根据所述车辆位置信息获取当地连续几天的天气情况。
服务器接收到车辆客户端发送的车辆位置信息,通过网络可以获取车辆所在地连续几天的天气情况。
步骤2、通过所述天气情况以及所述路面状况信息确定路面阻尼系数。
