FÖRELÄSNING V.7 TRUE/FALSE Flashcards
A heartbeat in a cooperative system is a periodic signal
TRUE
It is possible to implement a cooperative system without using wireless communication.
FALSE
Platooning (cooperative ACC) requires that at least 80% of the cars in the platoon are equipped.
FALSE
A critical mass of at least 10% equipped car is necessary for most of the cooperative applications to be effective
TRUE
In a cooperative application the ego-vehicle is the vehicle getting the warning
TRUE/FALSE
Cooperative systems always require broadcast communication
FALSE/TRUE
Longer latencies are desirable for the development of cooperative safety applications.
FALSE
Only a limited amount of information should be transmitted at high frequency rate in order to limit the use of the bandwidth.
TRUE
Beaconing alone can enable simple cooperative applications
TRUE
An LDM is a common database which each vehicle can assess wirelessly
FALSE
It is necessary to have strict regulations about transmission power only to limit energy consumption.
FALSE
Heartbeats should contain minimal information since they are periodic signals and many vehicles may be transmitting simultaneously.
TRUE
The Deming’s cycle explains how system development and evaluation may happen in a continuous loop to improve the system.
TRUE
A validation plan is often more comprehensive than a test plan and may include human factor issues.
TRUE
If a warning system has specificity 1 cannot have sensitivity 1
FALSE
A cost-benefit analysis may be able to tell how much money society may save as the percentage of vehicles with AEB increases.
TRUE
A TRL9 system is probably on the market, a TRL2 system may not even be a prototype.
TRUE
If the specificity of a system is 0.5 and the sensitivity is 0.5, we can just as well flip a coin.
TRUE
LDW can accept lower specificity than FCW.
TRUE
The ecological validity of test-tracks and driving simulators is hard to measure and still to be proven in several contexts.
TRUE
One of the main advantages of driving simulations is the possibility to explore safety critical situation with good repeatability.
TRUE
Test tracks can expose a vehicle to different environments such as slippery road.
TRUE
Whether test-tracks or driving simulators are the best environment for active safety development depends on the specific research questions of the study.
TRUE
Field operational test are performed as soon as a prototype is available
FALSE
