170918 - Active Safety Development

Question 1

Crashes happen when drivers exceed their comfort zone.

Answer 1

False

Question 2

Drivers do not optimally control their vehicles.

Answer 2

True

Question 3

Crash scenarios need to be determined and a causation mechanism understood before active safety systems may be developed.

Answer 3

True

Question 4

A crash may happen as a consequence of an adaption failure such as the driver underestimating the deceleration of the vehicle in front.

Answer 4

True

Question 5

A typical crash scenario for lane departure warning would be a run-off-road crash.

Answer 5

True

Question 6

A typical use case for a distance alert system would be based on a car-following situation.

Answer 6

True

Question 7

Over time, active safety systems improve by increasing the number and variety of crash scenarios and use cases that they can address.

Answer 7

True

Question 8

TTC is lower than TH if the vehicle in front is braking.

Answer 8

True

Question 9

TTC = TH for stationary objects.

Answer 9

True

Question 10

Required deceleration may be very different even when TTC is the same.

Answer 10

True

Question 11

Threat assessment algorithms may estimate in real-time the necessary J and S to avoid a collision.

Answer 11

True

Question 12

Decision making algorithms base their decision of what a driver and the vehicle are able to do (driver models).

Answer 12

True
