METHOD OF IDENTIFYING POSITIONS OF WHEEL MODULES

摘要

A method of identifying locations of one or more modules (400) of an apparatus (600, 680, 690, 2200) implemented in a vehicle (900) for monitoring operation of at least one wheel (10) of the vehicle (900), said apparatus (600, 680, 690, 2200) including one or more sensor modules (400) operatively mounted to revolve with said at least one wheel (10), said one or more modules (400) being operatively coupled in communication with a processing arrangement (710, ECU 950) of said vehicle (900), said one or more modules (400) being operable to sense at least one physical parameter of said wheel (10) and to generate at least one corresponding sensor signal for said processing arrangement (950), said processing arrangement (710, ECU 950) being operable to process said at least one sensor signal to compute information indicative of operation of said at least one wheel (10),, characterized in that said method includes steps of (a) communicating with one or more modules (400) of said apparatus (680, 690, 2200) for receiving their identification codes (ID) at a processing arrangement (950) of said apparatus (680, 690, 2200), said one or more modules (400) being mounted on at least one wheel (10) of said vehicle (900); (b) driving said vehicle (900) around a curved trajectory as sensed by said steering sensing arrangement and recording a direction of steering of said vehicle (900) together with a temporal record of said physical parameter measured by said one or more modules (400) together with their corresponding identification codes (ID), said physical parameter pertaining to one or more tyres (30) of said at least one wheel (10); and (c) applying an analysis to said steering direction and said temporal record in respect of time to identify where said one or more modules (400) are located on said at least one wheel (10) of said vehicle (900), said analysis utilizing a characteristic that tyres (30) on an outside of said curved trajectory will experience a different peak values in said temporal record of said physical parameter than tyres (30) on an inside of said curved trajectory, and that tyres (30) towards a front region of said vehicle (900) experience a change in the temporal record of said physical parameter before and/or at a higher rate than tyres (30) towards a rear region of said vehicle (900) for a forward direction of travel of vehicle (900).
