Crash Detection leverages an advanced sensor-fusion algorithm and a new, more powerful accelerometer and gyroscope in Apple Watch to detect and deliver accurate car crash alerts, and if a user is unresponsive after a 10-second countdown, will dial emergency services. When a severe crash is detected, the emergency services call interface will appear on Apple Watch, as it is most likely to be in closer proximity to the user, while the call is placed through iPhone if it is in range for the best possible connection. When combined with Apple Watch, Crash Detection seamlessly leverages the unique strength of both devices to get users help efficiently.

Advanced Apple-designed motion algorithms trained with over a million hours of real-world driving and crash record data provide even better accuracy.

These capabilities build on existing components, like the barometer, which can now detect cabin pressure changes, the GPS for additional input for speed changes, and the microphone, which can recognize loud noises typified by severe car crashes. With a new dual-core accelerometer capable of detecting G-force measurements of up to 256Gs and a new high dynamic range gyroscope, Crash Detection on iPhone can now detect a severe car crash and automatically dial emergency services when a user is unconscious or unable to reach their iPhone. The entire iPhone 14 lineup introduces groundbreaking safety capabilities that can provide emergency assistance when it matters most. Crash Detection uses specialized components paired with Apple-designed algorithms to detect a severe car crash and automatically dial emergency services when a user is unconscious or unable to reach their iPhone.

Rollercoaster riders in recent days have been accidentally calling emergency services as the extreme motions of the rides set off iPhone 14’s car Crash Detection feature.
