 　　Virtual Driver虚拟驾驶员

　　Driving involves sharp eyes and keen ears，analyzing with a brain，and coordination between hands，feet and brain. A man has sharp eyes and keen ears，analyzes through his brain，and maintains coordination between his hands and brains. He can control a fast-moving car with different parts of his body. (1)_ _ Apparently there isn't anyone in the driver's cab，but there is in fact a virtual driver1. This virtual driver has eyes，brains，hands and feet too. The minicameras on each side of the car are its eyes and are responsible for observing the road conditions ahead of it as well as the traffic to its left and right. If you open the boot，you can see the most important part of the automatic driving system: a built-in computer. (2)_ _ _ The brain of the car is responsible for calculating the speeds objects surrounding the car are moving at2, analyzing their position on the road, choosing the right path, and giving orders to the wheel and the control system.

　　驾驶需要敏锐的视觉与听觉，大脑分析，手、脚和大脑的协调配合。人具有敏锐的视觉与听 觉能力，能用大脑进行分析，保持手和大脑的配合。人能用身体不伺部位来操控一辆快速行驶的 汽车，但是智能化的汽车怎样自动驾驶呢?显然驾驶室里无人驾驶，但事实上的确存在一个虚拟 驾驶员，它有眼睛、大脑和手、脚。汽车两边的小型照相机就是它的眼睛，负责观察前方的路况 信息和左右两侧的交通状况。如果你打开车身后部的行李箱，你就会看到自动驾驶系统中最重要 的部件：嵌入式计算机。它是汽车的大脑，这个大脑负责计算汽车周围物体移动的速度，分析它 在路上的位置，选择正确的道路，并对方向盘和操控系统下达指令。

　　In comparison with the human brain, the virtual driver's best advantage is that it reacts quickly. (3)_ _ However, it takes the world's best racecar driver at least one second to react, and this doesn't include the time he needs to take action.

　　与人脑相比，虚拟驾驶员最大的优点是反应快。对照相机发送的图像，能在100毫秒内完成 对其的分析处理。可是世界上最好的赛车手至少要1秒钟内才能做出反应，并且这个时间还不包 括他采取应对措施的时间。

　　With its rapid reaction and accurate control，the virtual driver can reduce the accident rate on expressways considerably. In this case, is it possible for us to let it have the wheel3 at any time and in any place? ___4___. With its limited ability to recognize things, the car can now only travel on expressways.

　　由于虚拟驾驶员反应迅速，操控准确，它能大量减少高速公路的事故率。在这种情况下， 是不是可以不分时间、不分地点都让虚拟驾驶员驾驶汽车?专家们认为目前尚不可以。由于虚拟 驾驶员识别物体的能力有限，目前这种智能化汽车只可以在高速公路上行驶。

　　The intelligent car determines its direction by the clear lines that mark the lanes clearly and recognizes vehicles according to their regular shapes. ___5___. This being the case4, people still have high hopes about driverless cars， and think highly intelligent cars are what the cars of the future should be like5.

　　智能汽车按清晰标出的车道线决定自己的行车方向，靠车辆的常规形状识别其他车辆。然而, 它却不能识别在普通道路上行驶的没有清晰标记的自行车和行人。虽然情况是这样，人们始终认为未来的汽车就应该是高度智能化的汽车。
