- Sudden speed shifts
- A new high g‑force accelerometer senses extreme accelerations or decelerations up to 256 Gs.
- Abrupt changes in direction
- A high dynamic range gyroscope monitors drastic changes in a car’s orientation.
- Laboratory crash tests
- We developed advanced motion algorithms by performing head-on, rear-end, side-impact, and rollover crash tests.
- Cabin pressure changes
- The barometer can detect pressure changes caused by deploying airbags.
- Loud sound levels of impact
- While you’re driving, the microphone identifies the extreme sound levels of a collision. For privacy, all processing is done on your iPhone.
- Real-world crash data
- We used public crash data from accidents to make Crash Detection as accurate as possible.
