If this happens, your iPhone or Apple Watch will first try and call 911 through your regular carrier network. Ironically, crashing your car in a remote area is when you need help the most and are least likely to get it. "It’s all a pretty dynamic algorithm.” 4. Huang said that a car's speed, impact, pressure change, and even sound level all help to determine whether the feature is triggered. Given that the factors involved in a car accident are varied and unique, Crash Detection is designed to analyze the data for the sum of its parts. It's about how the sensors tell the whole story. "It’s not a straight equation."Ĭrash Detection needs to factor in all of these data points to determine if there's been a crash - it's not just one overruling data point or specific calculation that triggers it. This was all to ensure that the feature would be hard to trigger and wouldn't accidentally go off if you dropped your phone. The tech company even gathered historical data from the Department of Transportation and the NHTSA (National Highway Traffic Safety Administration) to understand injury-likely crashes. That includes GPS to infer high speeds, microphone activity for the sounds of a crash, a barometer to detect pressure if the airbags are deployed, and even Bluetooth and CarPlay to inform your device that you're in a car.Īpple also worked extensively with crash labs to simulate crashes and gather data. Crash Detection also takes multiple factors into account. A symphony of sensorsīut G-Force sensors aren't the only technologies that determine whether a crash has taken place. Suffice to say, Crash Detection has got you covered in the G-Force department. Serious car accidents are around 100 Gs or higher. That was one of the key differences for the new accelerometers that the new watches and phones have.”įor context, the highest G-Force survived by a human was the 214 Gs Indycar driver Kenny Brack experienced when he crashed his racecar, which was going 220 mph at the time, at the Texas Motor Speedway. "It’s able to detect G-Force up to 256 Gs. "It’s mostly the G-Force detection,” Drance told TechCrunch. G-Forces aren't just for 'Top Gun'Ĭrash Detection is made possible because of new advancements to the gyroscope and accelerometer - sensors within the iPhone and Apple Watch that detect motion and speed. even sometimes when it's not supposed to, like when you're on a rollercoaster.īut how exactly does Crash Detection work? And why would a rollercoaster ride trigger it?Īpple execs Ron Huang, vice president of sensing and connectivity, and Kaiann Drance, vice president of worldwide iPhone marketing, spoke to tech blog TechCrunch to pull back the curtain on what went into making the new features. And we already know it works as advertised. Earlier this fall, Apple announced a new feature called Crash Detection for the iPhone 14 and Apple Watch Series 8.
