How does Crash Detection on iPhone work?
Crash Detection on iPhone is one of Apple’s rescue features that many people appreciate for its accuracy and usefulness. In fact, many people have been saved thanks to this feature. In this article, I will talk more clearly about how Crash Detection works on iPhone.Crash Detection on iPhone and Apple Watch uses a number of sensors to detect car crashes (in some cases on motorcycles as well), including:
Accelerometer: This sensor measures the device’s acceleration. When the device is impacted, the accelerometer will record a sudden increase in acceleration.
Gyroscope sensor: This sensor measures the rotation angles of the device. When the device is impacted, the gyroscope sensor will record the sudden change in the device’s rotation angles.
Collision detection is made possible by new improvements to the gyroscope and accelerometer – sensors inside iPhone and Apple Watch that detect the movement and speed of a person’s movement. use it. In addition, Crash Detection also relies on many other factors including GPS to infer speed, microphones to record impact sounds, and barometers to detect pressure if airbags are activated.
When these sensors detect a potentially injury-causing collision, the Crash Detection feature takes the following steps:
– The feature will emit an audible and vibration alert.
– he feature will ask the user to confirm that they are okay.
– If the user does not respond within 10 seconds, the feature will automatically call emergency services.
Share from Apple:
– “This is not a simple equation.” said Ron Huang (vice president of sensors and connectivity). The reason why Huang said this is not a simple equation is because to activate this feature, its operation needs to process a lot of different information and conditions as stated above.
– “Mostly because of the G-Force detection,” Drance told TechCrunch. “It can detect G-Force up to 256 Gs. That’s one of the key differences with the new accelerometer on the new iPhone and Apple Watch.” To put this into perspective, the highest G-Force ever endured by a human being was the 214 Gs experienced by Indycar driver Kenny Brack when he crashed his race car, the car was traveling at 220 mph, at Texas Motor Speedway racetrack. Serious car accidents are often in the range of 100 Gs or more.
