Systems and methods for detecting a vehicle static condition
First Claim
1. A navigation system comprising:
- a sensor operative to detect at least one of acceleration and angular rate of a vehicle, the sensor being operative to generate a vehicle vibration profile based on the at least one of the detected acceleration and angular rate of the vehicle, wherein the vehicle vibration profile comprises comparing at least one of a peak-to-peak variation and a standard deviation of the detected data; and
a computing device operative to receive the vehicle vibration profile from the sensor, the computing device being operative to determine whether the vehicle is stationary or moving based on the vehicle vibration profile.

Abstract
Systems and methods for detecting a vehicle static condition are provided. In this regard, a representative system includes a sensor operative to detect at least one of acceleration and angular rate of a vehicle. The sensor is further operative to generate a vehicle vibration profile based on the at least one of the detected acceleration and angular rate of the vehicle. The system further includes a computing device operative to receive the vehicle vibration profile from the sensor, the computing device being further operative to determine whether the vehicle is stationary or moving based on the vehicle vibration profile. A representative method for detecting a vehicle static condition includes detecting at least one of acceleration and angular grade of a vehicle; generating a vehicle vibration profile based on at least one of the detected acceleration and angular grade of the vehicle; receiving the vehicle vibration profile; and determining whether the vehicle is stationary or moving based on the vehicle vibration profile.
