Description

具有冗余爆胎监测的跟驰汽车
本申请为申请号201410469860X、申请日2014年9月16日、发明名称“具有冗余爆胎监测的跟驰汽车”的分案申请。
技术领域
本发明涉及跟驰汽车领域，具体地，涉及一种具有冗余爆胎监测的跟驰汽车。
背景技术
汽车跟驰是后车跟随前车的行驶状态，即前车和后车达成信息沟通，后车根据前车的信息，对比前后车参数差异，将其换算为后车驾驶方案而实现自动驾驶。在自动跟驰驾驶技术中，跟驰汽车根据前车的行驶参数进行行驶。车辆在行驶途中，会有很多突发状况，譬如：爆胎，而车辆在行驶过程中爆胎的后果是十分严重的。在跟驰车队中，为了在一定距离的道路上容纳更多的跟驰汽车，相邻两个车辆之间的安全行驶距离可缩短为20米甚至更短，而车辆在高速行驶过程中因爆胎而导致汽车失去操控性能所需时间约3秒，这与驾驶制动反应时间基本吻合，而在这么短的距离内实现对跟驰车队的安全控制是十分重要的，现有的汽车在爆胎时仅对人以警示，而人的反应速度慢。且汽车爆胎的状况不是时有发生，汽车长久使用，爆胎监测装置易发生状况，即达不到对爆胎状况的监测。
发明内容
本发明所要解决的技术问题是提供一种跟驰汽车，其具有冗余爆胎监测功能，实现对爆胎的可靠监测，且在爆胎时采取应对措施快，避免交通事故的发生。
本发明解决上述问题所采用的技术方案是：具有冗余爆胎监测的跟驰汽车，包括：第一爆胎监测装置和与第一爆胎监测装置互为冗余的第二爆胎监测装置，所述的第一爆胎监测装置和第二爆胎监测装置均连接在自动驾驶分析***上，所述的自动驾驶分析***上连接有跟驰汽车状态控制装置，所述的第一爆胎监测装置包括速度传感器、胎压监测装置和胎内气流速度采集装置，所述的第二爆胎监测装置包括路面信息采集装置、车辆载重采集装置和轮压采集装置，所述的自动驾驶分析***上还连接有定位装置，所述的自动驾驶分析***上还连接有实现跟驰汽车之间通讯的通讯***。
作为优选，所述的跟驰汽车状态控制装置包括挡位、刹车、信号灯和离合。
作为优选，所述的通讯***包括跟驰汽车之间的车间通讯***和司乘人员之间的车间司乘通讯***。
作为优选，所述的轮压采集装置为压力传感器。
作为优选，所述的自动驾驶分析***为单片机控制芯片。
作为优选，所述的路面信息采集装置包括光电扫描设备和摄像/照相设备。
作为优选，所述的自动驾驶分析***上连接有告警装置。
综上，本发明的有益效果是：
1、本发明的采用两个爆胎监测装置对跟驰汽车的爆胎状况进行冗余监测，提高爆胎监测的可靠性，避免一个爆胎监测装置出现状况。
2、本发明利用自动驾驶分析***对爆胎状况进行分析判断，其反应速度快，出现爆胎及时对跟驰汽车状态控制装置进行控制，还通过告警装置通知司乘人员，提高驾乘的安全性。
具体实施方式
下面结合实施例对本发明作进一步地的详细说明，但本发明的实施方式不限于此。
实施例1：
具有冗余爆胎监测的跟驰汽车，包括：第一爆胎监测装置和与第一爆胎监测装置互为冗余的第二爆胎监测装置，所述的第一爆胎监测装置和第二爆胎监测装置均连接在自动驾驶分析***上，所述的自动驾驶分析***上连接有跟驰汽车状态控制装置，所述的第一爆胎监测装置包括速度传感器、胎压监测装置和胎内气流速度采集装置，所述的第二爆胎监测装置包括路面信息采集装置、车辆载重采集装置和轮压采集装置，所述的自动驾驶分析***上还连接有定位装置，所述的自动驾驶分析***上还连接有实现跟驰汽车之间通讯的通讯***。
本发明在现有跟驰汽车的基础上做了改进，即在现有的自动驾驶分析***上增设两个爆胎监测装置，实现对爆胎状况的冗余监测，提高可靠性，于此同时，利用自动驾驶分析***对爆胎的状况进行分析判断，出现爆胎时，不仅即刻对跟驰汽车状况控制装置进行控制，及时采取应对措施，自动驾驶分析***做出反应的时间小于0.01秒，其反应快，可有效的减小交通事故的发生，且及时通知司乘人员，提醒司乘人员注意，提高驾乘的安全性。本发明采用2种方式对爆胎状况进行检测，第一爆胎监测装置的速度传感器、胎压监测装置和胎内气流速度采集装置分别对车速、轮胎内气压和胎内气流速度进行采集;第二爆胎监测装置的路面信息采集装置、车辆载重采集装置和轮压采集装置分别对路面信息、载重和轮压进行采集。其一，车辆的行驶速度、轮胎的胎压和轮胎内的气流速度成一定的关系，如果轮胎内的气流速度异常，则自动驾驶分析***判断爆胎;其二，跟驰汽车根据前方车辆发送的各路段的路面资料、本车载重和轮压结合计算，当跟驰汽车某个车轮的轮压明显不符时，自动驾驶分析***则判定为车辆爆胎。跟驰汽车之间通过通讯***进行信息交互，当跟驰汽车接收到前方车辆的爆胎信息后，爆胎车辆后方的自动驾驶分析***即刻控制跟驰汽车状态控制装置对车辆进行减速、刹车或转弯等处理，爆胎车辆也即可采取刹车等措施。
实施例2：
本实施例在上述实施例的基础上做了细化，所述的跟驰汽车状态控制装置包括挡位、刹车、信号灯和离合。在车辆出现爆胎时，爆胎的跟驰汽车可采取减速、换道等处理，即自动驾驶分析***控制对刹车、方向盘和转向灯进行处理;当爆胎车辆进行减速时，为了实现后方车辆的继续跟驰，后方车辆可采取换道，即对刹车、方向盘和转向灯进行控制;当爆胎车辆进行换道时，后方车辆仍可保持同一车道进行行驶。
实施例3：
本实施例在上述实施例的基础上做了细化，所述的通讯***包括跟驰汽车之间的车间通讯***和司乘人员之间的车间司乘通讯***，车间司乘通讯***和车间通讯***实现信息通讯，其不仅给驾驶人员，也给自动驾驶分析***。
实施例4：
本实施例在上述实施例的基础上做了细化，所述的轮压采集装置为压力传感器所述的自动驾驶分析***为单片机控制芯片。单片机控制芯片进行控制分析，其数据处理速度快。
实施例5：
本实施例在上述实施例的基础上做了细化，所述的路面信息采集装置包括光电扫描设备和摄像/照相设备。路面破损状况检测装置在对道路信息进行采集时，光电扫描设备和摄像/照相设备同时工作，对路面的信息进行采集，进一步增强对路面信息采集的准确性。
实施例6：
本实施例在上述实施例的基础上做了细化，所述的自动驾驶分析***上连接有告警装置。爆胎时，自动驾驶控制分析***立即通告警装置对司乘人员以告警，提醒驾驶人员注意，进一步可采用声光告警装置，增强警醒作用。
如上所述，可较好的实现本发明。
