What is news?

After the crash of an aircraft, its black box is first discovered, so that the causes behind the accident can be ascertained. Very few people will know that cars also have a black box, officially called the event data recorder (EDR), found in almost all modern cars. It is helpful in finding the causes of the accident. Let us know how the black box of the car works.

How does EDR work?

The black box or EDR of the car is commonly found in the Poetrain Control Module (PCM) or Airbag Control Module (ACM). The device locks the information just before the accident occurs from various sensors and after that. This will collect data of car speed, brake position, steering wheel angle, road inclination and seatbelt use status. In such a situation, if there is an accident of a car, then all the information will be revealed from it.

Benefit

What is the benefit of EDR?

EDR helps understand the causes and circumstances of accidents, which helps determine what and how it happened. Its data is helpful in evaluating claims to insurance companies and preventing fraud. It is used in safety research, so that it can be understood how accidents occur and how to improve design and safety measures to prevent future accidents.
