Answer 10

TRUE

Question 11

Active safety is more concerned with the causes of a crash than with its outcome

Answer 11

TRUE

Question 12

Intelligent transport systems not only are concerned about safety, but also about environment- and mobility-related issues

Answer 12

TRUE

Question 13

ADAS are installed inside a vehicle, ITS not necessarily.

Answer 13

TRUE

Question 14

Answer 15

FALSE

Question 16

Lane departure warns in the post-crash phase.

Answer 16

FALSE

Question 17

Understanding the driver may help active safety systems to identify critical situations that
may develop in crashes.

Answer 17

TRUE

Question 18

Active safety systems use sensors to understand the world, algorithms to assess threats
and decide interventions, and HMI/actuators to issue warnings or initiate automated
interventions.

Answer 18

TRUE

Question 19

Active safety systems issue warnings via an HMI.

Answer 19

TRUE

Question 20

ACC is a lateral control system providing sustained support.

Answer 20

FALSE

Question 21

The only sensor needed for ACC is a radar.

Answer 21

FALSE
