Method for characterization of state of traveler between mobile state and autonomous state, involves triggering signal state change when frequency component of greater amplitude corresponds to frequency included in preset interval

摘要

The method involves periodically recording a standard acceleration detected by an accelerometer. A fast Fourier transform of a recorded signal is calculated. A signal state change is triggered when a frequency component of a greater amplitude corresponds to a frequency included in a preset interval, and recorded during a step of training during which the traveler carries out an autonomous displacement, for a time length higher than a reference value corresponding to a nominal time of autonomous displacement of a traveler inside a vehicle e.g. bus. An independent claim is also included for a downloadable computer program comprising instructions for performing a method for characterization of a state of a traveler between a mobile state and an autonomous state.
