METHODS FOR DETERMINING ORIENTATION OF A MOVING VEHICLE
First Claim
1. A method for determining orientation of a moving vehicle, whereinin case the orientation is determined by a device installed at a fixed position within said moving vehicle, the method comprises:
- collecting data which relate to acceleration forces measured along at least one of the vehicle axes, selected from among the longitudinal (x) axis of the vehicle being driven and the latitudinal (y) axis of the vehicle being driven, together with corresponding GPS related information;
calculating correlations between the measured accelerations and velocity changes and/or vehicle'"'"'s heading changes;
associating the calculated correlations with a plurality of possible yaw rotation angles and derive therefrom a yaw rotation angle that would maximize the correlation; and
based on a yaw rotation angle that would maximize the correlation derived, determining the orientation of said moving vehicle;
in case the orientation is determined by a mobile wireless device placed in said moving vehicle at a non-predefined position, and which comprises at least one accelerometer, the method comprises collecting data obtained by said mobile wireless device during a driving session from a Global Positioning System (GPS) and from acceleration measurements made by the at least one accelerometer of said mobile wireless device.

Abstract
A method is provided for determining orientation of a moving vehicle. Using a fixed position device, the method comprises: collecting data which relate to acceleration forces measured along the vehicle axes together with corresponding GPS related information; calculating correlations between measured accelerations and velocity changes and/or vehicle'"'"'s heading changes; associating the calculated correlations with a plurality of possible yaw rotation angles and derive therefrom a yaw rotation angle that maximizes the correlation; and based on a yaw rotation angle that would maximize the correlation derived, determining the orientation of the moving vehicle. Using a mobile device placed in the vehicle in an unknown position, the method comprises collecting data obtained by the mobile device during a driving session from a GPS and from acceleration measurements made by an accelerometer of the mobile device.
