1. An adaptive motion sensor system on a transport vehicle, comprising:
- a vibration sensor;
an adaptive threshold component that receives input values based on readings of said vibration sensor, said adaptive threshold component identifying a threshold value between two peak values on a histogram of said received input values, said two peak values representing two different operating states of the transport vehicle; and
a motion detection component that receives input based on readings of said vibration sensor and said identified threshold value from said adaptive threshold component, said motion detection component determining an operating state of the transport vehicle through an analysis of said received input relative to said identified threshold value.

12. An adaptive motion sensor method in a transport vehicle, comprising:
-
a)generating input data from vibration sensor readings on the transport vehicle; and b)determining an operating state of the transport vehicle based on an analysis of said input data relative to a threshold data value, wherein said threshold data value is adjustable based on an analysis of said input data through an identification of a null value between two peak values on a histogram of said input data, said adjustability being used to account for changes in operating characteristics of the transport vehicle over time. - View Dependent Claims (13)
