Abstract

A method and a device for low-power acceleration detection in a stationary vehicle are provided. The method includes putting a telematics device into a sleep mode, performing a plurality of micro wakeups during which a plurality of accelerometer readings are captured. The method further includes sending the plurality of accelerometer readings over a network interface to a telematics server. The telematics device which carries out the method has a controller, memory, and network interface. An accident impact profile may be recorded during the micro wakeups and sent during a regular wakeup duration for analysis by the telematics server.
