Activity

I. Your brother started working in a prosperous engineering company last year and he has saved enough money for a small, cheap car. Discuss advantages and disadvantages of buying a small car and give your brother a piece of advice.

II. Science and new technology are gradually changing everything in our life. Can you imagine how a car of the future will look like? Look at these statements and express your opinion on them. Give some other ideas of your own. Start with the phrases from the box.

EXPRESSING CERTAINTY AND DOUBT;

I'm (not)

certain

(that)…

(quite)

sure

convinced

positive

There's no doubt that…

I doubt that/if..

1. All the cars will be of one colour, yellow.

2. The cars will not run on petrol.

3. There will be a lot of electric cars.

4. Some cars will run on solar energy.

5. Every car will have an air bag in front of the driver.

6. A driver will not have to drive a car because it will be automatic.

7. …

Writing

I. How do you imagine a car of the future? Write a short description of it.

II. Translate this text into Ukrainian. What Is Mechatronics?

The word mechatronics was first used in 1969 to describe the inte­gration of precision mechanical engineering (точна механіка) with electronic and computer control systems in order to make intelligent machines. Scientists wanted to bring together branches of engineering that are normally studied in isolation, in the hope that the design solutions will benefit both electrical and mechanical disciplines.

The range of applications of mechatronics is enormous and includes domestic appliances, automated assembly lines, computer peripherals and so on. Some specialists predict that mechatronic sys­tems will be widely used in cars of the future. Mechanical devices will be controlled by the computer systems and thus the car's stability will be increased. On the whole a car will become a more efficient means of transport. All the mechatronic systems will operate inde­pendently and will help the driver control the motion of the vehicle.

II. Look at the picture below and try to guess what this text deals with.

III. This is an extract from an article published in one of the British journals. Read it attentively and learn how some engineers imagine the future of the car.

T he vehicle of the future will be designed in a different way. These will be automatic vehicles with ACC or adaptive cruise control. The principle is that the car automati­cally adjusts its speed relative to its distance from and the speed of another vehicle. This removes the need for the driver to control the accelerator and thus the driver workload will be reduced conside­rably. ACC is a part of the longitudinal control of the vehicle.

The next step in automating the longitudinal control is automatic braking systems (ABS) Here, the driver will be informed by these sys­tems that a dangerous situation can arise unless action is taken. If the driver fails to respond, the brakes will be automatically applied and vehicle stability and driver safety will be maintained.

Laser and vision technologies are used to detect objects and ensure lateral control of the vehicle. The first systems will assist the driver through warnings; more advanced systems will use steer-by-wire systems to adjust the vehicle heading automatically.

The combination of lateral and longitudinal control of the vehicle motion is a new feature of the vehicle which will be used in an auto­mated highway system.

IV. Answer these questions.

1. Will the vehicle of the future be the same as nowadays?

2. What kind of a car will we have?

3. What is ABS?

4. What is used to detect objects around a vehicle?

5. Would you like to have such an automatic vehicle with ACC and ABS? Give your reasons.

V. Annotate the text.
