METHOD FOR DETERMINING THE LENGTH OF THE FOOTPRINT ON THE GROUND OF A PNEUMATIC WHEEL OF A VEHICLE

摘要

The invention relates to a method for determining, during the running of a vehicle, the length of the impression on the ground of a tire (7) comprising a metal reinforcement, fitting a rim (6) of a wheel of the tire. said vehicle. According to the invention, this method consists in mounting a magnetic sensor (8) on the rim (6) and in analyzing the signal representative of the magnetic field measured by the said magnetic sensor, so as to detect the variations of the magnetic field resulting from the deformations. that a circumferential zone of the tire (7) facing the magnetic sensor (8) is subjected when, respectively, the said circumferential zone comes into contact with the ground and leaves the ground.
