How does your phone know you've been in an accident?

They have a high dynamic range gyroscope and a new dual-core accelerometer. With them, your phone can automatically notify emergency services and your emergency contacts if you're in a serious car accident. If your iPhone or Apple Watch detects a serious car accident, the device can help you connect to emergency services. But what if you can't access your phone? Technology is now advancing to the point where the phone can detect the impact of an accident.

There are apps that contact medical assistance and send them to your location when they detect an accident. When the iPhone detects a serious car accident, it will display an alert and automatically initiate an emergency phone call after 20 seconds, unless you cancel it. Texting or checking social media while driving is still a dangerous move that can cause an accident, but you don't have to leave your phone at home. Life360 requires that the permission to share the location be set to “Always” in the phone settings in order to detect driving events.

The phone's accelerometer detects the phone's acceleration (a pretty good indication of movement, such as driving a car). This way we'll know when your phone is spinning around in the cup holder or falls out of your hands on the street while you walk (we hope that doesn't happen). While distracted driving may be caused by changing the radio or trying to eat and drive at the same time, one of the main causes of distracted driving are phones. While you're driving or traveling as a passenger in a motor vehicle, the iPhone or Apple Watch's motion sensor works together with a high-dynamic range gyroscope and a high-frequency accelerometer, the GPS, the barometer, the microphone and the advanced motion algorithms of the iPhone or Apple Watch to accurately detect a crash.

If the iPhone or Apple Watch detects a serious car accident and contacts emergency services, they will include the location of the device as latitude and longitude coordinates. Whether you're using a smartphone app like Life360, an Apple Watch, or another connected device, it's important to know how fault detection works and why it's so important. Almost everyone carries their mobile phone with them and now there are apps that will contact doctors in the event of a car accident. If you don't respond, the iPhone will play an audio message for emergency services informing them that you have had a serious accident and will provide them with your latitudinal and longitudinal coordinates with an approximate search radius.

If your iPhone has crash detection turned on and is connected to your vehicle through CarPlay, the crash detection functions (calling emergency services) will go through your iPhone. If you have a serious car accident and don't respond in a place without a mobile or Wi-Fi connection, your iPhone will try to contact emergency services using Emergency SOS satellite, if available.
