汽车智能技术简介

chenchen924
chenchen924 over 14 years ago

随着电子信息技术的飞速发展,形形色色的汽车智能技术在汽车上得到推广应用,充分体现出其安全、可靠、舒适、方便及快捷的优越性能。目前这些智能技术主要应用在以下几方面:

 

    智能驾驶系统 

 

    智能驾驶系统相当于智能机器人,能代替人驾驶汽车。它主要是通过安装在前后保险杠及两侧的红外线摄像机,对汽车前后左右一定区域进行不停地扫描和监视。计算机、电子地图和光化学传感器等对红外线摄像机传来的信号进行分析计算,并根据道路交通信息管理系统传来的交通信息,代替人的大脑发出指令,指挥执行系统操作汽车。

 

    智能轮胎 

 

    轮胎内装有计算机芯片或将芯片与胎体相连接。计算机芯片能自动监控并调节轮胎的行驶温度和气压,使轮胎在不同情况下都能保持最佳的运行状态,既提高了安全系数,又节省了开支。更为先进的智能轮胎还能在探测出结冰的路面后变软,使牵引力更好;在探测出路面的潮湿程度后,还能自动改变轮胎的花纹,以防打滑。

 

    智能钥匙 

 

    奔驰CLK双门轿车已采用了智能钥匙。这种智能钥匙发射出红外线信号,既可打开车门、行李舱和燃油加注孔盖,也可以在操纵汽车门把手时,使中央锁控制系统便开始工作,并发射一种无线查询信号。智能钥匙卡做出正确反应后,车锁便自动打开,而且只有当中央处理器感知钥匙卡在点火开关内时,发动机才能起动。

 

    智能空调 

 

    智能空调系统能根据外界气候条件,按照预先设定的指标对安装在车内的温度、湿度和空气清洁度传感器所传来的信号进行分析、判断,及时自动打开制冷、加热、去湿及空气净化装置,调节出适宜的车内空气环境。在先进的安全汽车上,空调系统可以配合驾驶。当驾驶员精神不集中或有瞌睡迹象时,能自动散发出使人清醒的气味。

 

    智能安全气囊 

 

    智能安全气囊是在普通安全气囊的基础上增设传感器和与之相配套的计算机软件而成。其质量(重量)传感器能根据质量感知乘客是大人还是儿童;红外线传感器能根据热量探测座椅上是人还是物体;超声波传感器能探明乘客的身体、身体质量、所处位置和是否系安全带以及汽车碰撞速度及撞击程度等,及时控制气囊的膨胀时机、膨胀速度和膨胀程度,使安全气囊为乘客提供最合理和最有效的保护。

 

    智能悬架 

 

    智能悬架系统由电子装置控制,可根据路面情况,调节悬架弹性元件的刚度和减振器的阻尼,使振动和冲击迅速消除。此外,智能悬架还可以自动调节车身的离地高度,即便是汽车在崎岖不平的路面上行驶,也会使乘客倍感平稳与舒适。
