SYSTEMS AND METHODS FOR DETECTING AN IMPACT EVENT IN A PARKED VEHICLE

Embodiments of the invention include a vehicle telematics system including a telematics device, wherein the telematics device detects, using a processor of a telematics device, a vehicle ignition off event and reconfigures at least one parameter of an accelerometer for a low power mode of operation while in the vehicle ignition off state, and places the telematics device in a sleep mode of operation, wherein an accelerometer generates an interrupt to wake the processor of the telematics device from the sleep mode of operation upon detecting an acceleration event that exceeds a threshold, and the processor of the telematics device analyzes the accelerometer data stored in a FIFO buffer of the accelerometer.
