LOW-POWER IMPACT ACCELERATION DETECTION IN A TELEMATICS DEVICE

A method and a device for low-power acceleration detection in a telematics device are provided. The method includes putting the telematics device into a sleep mode and performing a micro wakeup. In response to determining that a first value read from a sensor during the micro wakeup is greater than a noise threshold, converting the micro wakeup into a regular wakeup. The method also includes reading a second value from the sensor during the regular wakeup, and sending the first and second values during the regular wakeup. A telematics device for carrying out the method is provided.
