Practise driver assistance systems

Question 1

You are on the motorway with adaptive cruise control (ACC) switched on. You come up behind a car that is driving slower. What does your car do?

Accepted Answer

It brakes by itself and keeps enough distance

Answer

It warns you that you are getting too close, but keeps driving just as fast

Answer

It moves to the left by itself to overtake the car

Question 2

You are driving with ACC on and you come up to a traffic jam that is standing still. What do you have to take into account?

Accepted Answer

The system sometimes sees stopped traffic late, or not at all

Answer

The system always brakes in time and brings the car to a safe stop

Answer

The system turns on your hazard lights by itself as soon as it sees the jam

Question 3

Your car has blind spot detection (BSD). What do you do when you change lanes?

Accepted Answer

You still check your mirror and look over your shoulder

Answer

You rely completely on the light in your mirror

Answer

You only look over your shoulder if the light is broken

Question 4

What is automatic emergency braking (AEB) for?

Accepted Answer

Only as a last resort in a crash, if you do not brake in time

Answer

To take over the braking from you in busy traffic

Answer

To make your braking distance shorter every time you brake

Question 5

How does speed assist (ISA) know which speed limit applies?

Accepted Answer

With a camera that reads the signs, plus the map from the navigation

Answer

Only from GPS

Answer

Through a direct link with the national road authority

Question 6

What is the biggest benefit of ABS when you make an emergency stop?

Accepted Answer

Your wheels keep turning, so you can keep steering and swerve around things

Answer

Your braking distance gets much shorter on every road

Answer

Your tyres get more grip than they normally have

Question 7

Your car is about to skid in a bend. Which system brakes individual wheels?

Accepted Answer

ESP (electronic stability programme)

Answer

ISA (speed assist)

Answer

ACC (adaptive cruise control)

Question 8

When does lane keeping assist (LKA) steer for you?

Accepted Answer

When you drift over the line without indicating

Answer

As soon as you switch on your indicator

Answer

Only when you drive faster than 130 km/h

Question 9

Your parking sensors beep without stopping. What does that mean?

Accepted Answer

You have to stop right away: something is very close

Answer

The car is ready to park itself

Answer

The sensors are dirty and no longer measure anything

Question 10

What do mud or snow do to the parking sensors in your bumper?

Accepted Answer

The system can drop out or give a false alarm: beeping all the time, or seeing nothing

Answer

Nothing, the sensors simply measure straight through the dirt

Answer

The car measures the distance with GPS instead
