Question 6631
Regarding driver assistance systems (ADAS), what is the function of the event data recorder, or EDR?
- Analyze the vehicle's systems to assess the driver's state of alertness.
- Assess whether the driver is fit to drive an automated vehicle.
- Record and store information so that the causes of an accident can be determined.
Show answer and explanation
Correct answer: Record and store information so that the causes of an accident can be determined.
The black box, or EDR, records and stores vehicle data just before, during, and just after a crash, such as speed, whether the brakes were applied, and the status of the airbags. This data can help determine the causes of the crash. It doesn’t monitor the driver; fatigue and distraction systems do that.
