method of calibration of the positioning of a device of board for the acquisition and long-distance transmission of data relating to parameters of motorcycle and driving of motor vehicles and motorcycles.

摘要

A calibration method of the positioning of an onboard device of a vehicle with axes (x, y, z), wherein the device comprises at least one accelerometric sensor (S) which detects the accelerations to which the vehicle is subjected along axes (x′, y′, z′), angularly arranged with respect to the axes (x, y, z) of the vehicle with rotation angles (αx, αy, αz). The accelerometric sensor (S) acquires the acceleration values generated by the force of gravity G acting on the vehicle when the vehicle is stopped. A transformation matrix (R) is determined, wherein a first rotation angle (αx) and a second rotation angle (αy) are derived on the basis of acceleration values of the force of gravity detected along the axes (x′, y′, z′) when the vehicle is stopped, and a third rotation angle (αz) is derived on the basis of the determined travel direction of the vehicle.
