An Intelligent
Car Driving needs sharp eyes, keen ears, quick brain, and
coordination between hands and the brain. Many human drivers have all
(51) and can control a fast-moving car. But how does an
intelligent car control itself There is a virtual driver in the
smart car. This virtual driver has "eyes", "brains", "hands" and "feet", too.
The minicameras (52) each side of the car are his "eyes",
which observe the road conditions ahead of it. They watch the (53)
to the car’s left and right. There is also a highly (54)
driving system in the car. It is the built-in computer, which is the
virtual driver’s "brain". His "brain" calculates the speeds of (55)
moving cars near it and analyzes their positions. Basing on this
information, it chooses the right (56) for the intelligent
car, and gives (57) to the "hands" and "feet" to act
accordingly. In this way, the virtual driver controls his car.
What is the virtual driver’s best advantage He reacts (58)
. The minicameras are (59) images continuously to
the "brain." It (60) the processing of the images within 100
milliseconds. However, the world’s best driver (61) needs
one second to react. (62) , when he takes action, he needs
one more second. The virtual driver is really wonderful. He can
reduce the accident (63) considerably on expressways. In
this case, can we let him have the wheel at any time and in any place Experts
(64) that we cannot do that just yet. His ability to
recognize things is still (65) He can now only drive an
intelligent car on expressways.
