Саг of Future

Ever since Nicolas Cugnot, a Frenchman, invented the first

self-propelled road vehicle in 1770, there has been no shortage of

companies willing to make a better automobile. Over years their efforts

have given users the gasoline engine (дизель), the electric

starter, tubeless tires (бескамерная шина), fuel-injected engines

and anti-lock brakes (тормоз с антиблокировочным устрой-

ством), these are only a few innovations. What is next? Here are

some examples of what the car designers are working at in the

world today.

Engineers are experimenting with a state-of-art (новейший)

system that enables drivers to see better after dark. This «night vision

» system uses infrared sensors that can detect a human figure at

night more than 1,600 feet away. That's five times the distance at

which conventional headlights are effective. The sensors pick up

infrared rays emitted by any object that gives off heat. An image-

processing system scans the information from the sensors, creating

different images for different objects. The images are then

displayed on a cathode-ray screen built in a car's instrument panel.

It is like black-and-white photograph of an object ahead. And the

system is passive, which means no lights are needed to illuminate

the object in front of the vehicle. But the biggest problem will be reducing

costs and the other one is the size of the sensor mechanism

which is too big now.

One of the latest applications of sophisticated electronics is the

wheel-computerized system that not only monitors air pressure in

automobile tires but adjusts it automatically. In addition this system

enables a driver to set tire pressure while seated. The system

developed consists of three separate modules. The first is the instrument

panel display which houses the system's main microprocessor,

programming buttons (кнопка включения программы)

and warning signals. The second component is the detector drive

module (модуль привода) which is essentially four microchips attached,

in one unit, to the chassis. Each chip detecting pressure

changes that may occur, the transistors within the module signal

the third component — a programmable transducer (программируемый

преобразователь). The transducer attached to each wheel

changes the tire pressure accordingly.

However, some automobile experts think this system is too complicated

and costly. The design has to be simple and of low cost.
