Vehicle wheel rotation direction determining method for determining wheel`s left/right position, involves correlating angular position obtained by measuring physical unit and direction of variation of gravity to determine rotation direction

摘要

#CMT# #/CMT# The method involves emitting signals comprising information relative to variation of gravity measurement, when wheel (2) is in angular positions. A physical unit representing the angular position of the wheel during the emission of each signal, is measured. The angular position obtained by the measurement of the physical unit and direction of variation of the gravity are correlated for determining rotation direction of the wheel. #CMT# : #/CMT# An independent claim is also included for a device for determining rotation direction of a wheel of a vehicle. #CMT#USE : #/CMT# Used for determining rotation direction of a wheel of a vehicle (claimed) equipped with a tire pressure monitoring system, for determining the left/right position of the wheel. #CMT#ADVANTAGE : #/CMT# The method can be easily implemented and permits to determine the rotation direction of the wheel in a simple manner without utilizing complex and costlier units. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an accelerometer disposed on a wheel. 2 : Wheel 4 : Accelerometer 6 : Measurement direction 8 : Vertical direction 10, 12 : Rotation directions.
