System and method for indicating whether a vehicle crash has occurred

A first mobile computing device for detecting vehicle crashes, the first mobile computing device comprising:

• one or more processors;
• and
• a memory storing instructions thereon, wherein the instructions, when executed by one or more processors, cause the first mobile computing device to:
• detect a first sensor data output from a sensor of the first computing device within a vehicle that indicates a sudden change in movement;
• transmit, to a second mobile computing device within the vehicle, a first signal indicating the sudden change in movement of the vehicle to cause the second mobile computing device to operate in a beacon transmit mode;
• cause the first mobile computing device in the vehicle to operate in a beacon receive mode in response to transmitting the first signal, wherein the first mobile computing device in the vehicle listens for or receives signals from the second mobile computing device in the vehicle when the first mobile computing device is operating in the beacon receive mode;
• receive a second signal from the second mobile computing device in the vehicle operating in a beacon transmit mode, the second signal indicating that the second mobile computing device in the vehicle detected a second sensor data output indicating the sudden change in movement of the vehicle;
• and
• confirm, based on the detection of the first sensor data output and the second signal, that the-sudden change in movement of the vehicle is a crash.

A computer-readable storage medium comprising non-transitory computer-readable instructions stored thereon for detecting vehicle crashes, wherein the instructions, when executed by one or more processors of a first mobile computing device, cause the one or more processors to:

• detect a first sensor data output from a sensor of the first computing device within a vehicle that indicates a sudden change in movement;
• transmit, to a second mobile computing device within the vehicle, a first signal indicating the sudden change in movement of the vehicle to cause the second mobile computing device within the vehicle to operate in a beacon transmit mode;
• cause the first mobile computing device in the vehicle to operate in a beacon receive mode in response to transmitting the first signal, wherein the first mobile computing device listens for or receives signals from the second mobile computing device in the vehicle when the first mobile computing device is operating in the beacon receive mode;
• receive a second signal from the second mobile computing device in the vehicle operating in a beacon transmit mode, the second signal indicating that the second mobile computing device in the vehicle detected a second sensor data output indicating the sudden change in movement of the vehicle;
• and
• confirm, based on the detection of the first sensor data output and the second signal, that the-sudden change in movement is a crash.
