Abstract
A method and a system for impact detection in a stationary vehicle are provided. The method includes putting a telematics device into a sleep mode and performing a first micro wakeup. In response to determining that a first value read from a sensor during the micro wakeup is greater than a noise threshold, increasing a frequency of the micro wakeups and a sampling rate of the sensor. The method also includes reading a second value from the sensor during a second wakeup, performing a regular wakeup, and sending the first and second values during the regular wakeup.
