Systems and methods for detecting airbag deployment resulting from a vehicle crash

A method for detecting airbag deployment using a mobile device, the method comprising:

• operating a plurality of sensors of the mobile device, wherein the mobile device is disposed in a vehicle during a drive;
• obtaining a plurality of motion measurement signals from the plurality of sensors of the mobile device;
• monitoring, by a processor of the mobile device, at least one motion measurement signal of the plurality of motion measurement signals, wherein the processor monitors the at least one motion measurement signal for a first time window;
• calculating, by the processor of the mobile device, a first difference in the at least one motion measurement signal corresponding to a first leading edge of the first time window and a first trailing edge of the first time window;
• determining, by the processor of the mobile device, that the first difference exceeds a first threshold;
• in response to determining that the first difference exceeds the first threshold, monitoring by the processor of the mobile device, a pressure measurement signal, wherein the processor monitors the pressure measurement signal for a second time window;
• calculating, by the processor of the mobile device, a second difference in the pressure measurement signal corresponding to a second leading edge of the second time window and a second trailing edge of the second time window;
• determining, by the processor of the mobile device, that the second difference exceeds a second threshold;
• in response to determining that the second difference exceeds the second threshold, detecting the airbag deployment based on the first difference exceeding the first threshold and the second difference exceeding the second threshold;
• and
• based on detecting the airbag deployment:
• identifying a vehicle crash event;
• and
• transmitting a signal to at least one of the mobile device or a computer of a service provider to output an indication of the vehicle crash event.
