An Intelligent Car
Driving needs sharp eyes,keen ears,quick brain,and coordinationbetween hands and the brain.Many human drivers have alland can control a fast-moving car.But how does an intelligent car control itself?
There is a virtualdriver in the smart car.This virtual driver haseyes,brains,handsandfeet,too.The minicameraseach side of the car are hiseyes,whichthe road conditions ahead of it.They watch theto the cars left and right.There is also a highly automatic drivingin the car.It is the built-in computer,which is the virtual driverbrain.Hisbrainthe speeds of other moving cars near it and analyzes their positions.Basing on this information,it chooses thepath for the intelligent car,and gives instructions to the handsandfeetto act accordingly.In this way,the virtual driverhis car.
What is the virtual drivers best advantage?He reacts.The minicameras are bringingcontinuously to the brain.It completes the processing of the images within 100 milliseconds.,the worlds best driver needs at least one second to react.Besides,when he takes,he needs one more second.
The virtual driver is really wonderful.He can reduce the accidentconsiderably on expressways.In this,can we let him have the wheel at any time and in any place?Expertsthat we cannot do that just yet.His ability to recognize things is still limited.He can now only drive an intelligent car on expressways.
