Apple executives explain the iPhone 14 Pro car accident detection function in detail: it is a dynamic algorithm that sometimes deliberately does not trigger.
Apple introduced the “car accident detection” function in the newly released iPhone 14/Pro series and Apple Watch, which has attracted much attention. However, the triggering conditions for this feature seem a bit odd, with some users testing collisions that fail to trigger, while others are constantly alerted when riding a roller coaster.
In an interview with TechCrunch, two Apple executives discussed the car crash detection feature of the iPhone 14/Pro series, explaining some specific trigger conditions.
In an interview with Kaiann Drance, Apple’s vice president of global iPhone product marketing, and Ron Huang, Apple’s vice president of sensing and connectivity, the iPhone 14/Pro series and the new Apple Watch are equipped with new sensors that can detect sudden changes in motion and pressure, and the acceleration sensor can measure up to 256G value of .
Ron Huang said that in developing the feature, developers needed to “have a basic understanding of what’s going on during a car crash.” In a car accident, the acceleration generally exceeds 100G. In addition to data from the gyroscope and accelerometer sensors, the iPhone uses a number of other variables to understand whether the user is moving in the car and whether they have been involved in an accident.
Regarding the phenomenon that the alarm is not triggered after some car accidents, Drance said that the iPhone 14/Pro series or Apple Watch may have intentionally failed to contact emergency services.
IT House has learned that despite Apple’s efforts to avoid false calls to emergency services, there have been reports that the iPhone 14 keeps making 911 emergency calls while some people are riding the roller coaster. The false alarm call may be caused by the iPhone 14/Pro series sensors erroneously interpreting the acceleration of the roller coaster as a collision with another vehicle.
iPhone 14 around many cars,
Huang also talked about how Apple is testing the feature, the company will put the iPhone 14 around many cars, and Apple has also studied data from the U.S. Department of Transportation and the National Highway Traffic Safety Administration (NHTSA) to understand what types of accidents are injuries. main reason.
The Crash Detection feature for Apple devices is available for the iPhone 14/Pro series, Apple Watch SE (2nd generation), Apple Watch Series 8, and Apple Watch Ultra.
