第七篇An Intelligent智能的CarDriving needs sharp eyes，keen敏锐的 ears，quick brain脑，and coordination协调 between hands and the brain. Many human drivers have all_ these _and can control a fast-moving car. But how does an intelligent智能的 car control itself?There is a virtual事实上的driver in the smart聪明的 car. This virtual driver has eyes，brains，hands and feet，too. The minicameras小型照相机_ on _each side of the car are his “yes，which observe观察 the road conditions环境 ahead of it. They watch the_ traffic 交通to the cars left and right. There is also a highly_ automatic _driving system in the car. It is the built-in computer，which is the virtual drivers brain. His brain calculates the speeds of _other_ moving cars near it and analyzes their positions. Basing on this information，it chooses the right_ path _for the intelligent car，and gives_ instructions 指示、命令to the “hands and feet to act accordingly. In this way，the virtual driver controls his car.What is the virtual drivers best advantage优越性? He reacts反映quickly _.The minicameras_ sending _images continuously不断的 to the brain. It _ completes _the processing 处理of the images within 100 milliseconds毫秒. However，the worlds best diver _ at least _ needs one second to react._ Besides，when he takes action，he needs one more second.The virtual driver is really wonderful.
