170828- Introduction to Active Safety, True/False Flashcards
Traffic safety is one of the largest health problems worldwide.
True
The Heinrich’s triangle may help understand the relation among crashes with with different severity level.
True
Crash databases have little information about driver behavior.
True
The driver behavior is a contributing factor in 80-90% of the crashes.
True
Driver impairment includes physical disabilities.
False
The pre-crash phase is typically longer than the in-crash phase.
True
An active safety system must act before a crash happens.
True
Passive safety aims at preventing crashes.
False
The headrest is a passive safety system.
True
By increasing exposure, injuries can be reduced.
False
Intelligent transport systems not only are concerned about safety, but also about environment- and mobility-related issues.
True
ADAS are installed inside a vehicle, ITS not necessarily.
True
If a system is able to recognize a safety critical situation, thin it is an active safety system.
False
Active safety operates up to 1 second before crash.
False
Active safety systems should always issue a warning in the pre-crash phase.
False
Lane departure warning is an ADAS providing intermittent assistance.
True
Driver models and road-user models may help active safety systems to identify critical situations that may develop in crashes.
True
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.
True
Active safety systems issue warnings via an HMI.
True
ACC is a lateral control system providing sustained support.
False
The only sensor needed for ACC is a radar.
False
The ACC hardware is sufficient to also generate collision warnings and provide headway information to the driver.
True
The Haddon matrix provides a framework for safety analysis.
True
