Method of identifying positions of wheel modules
Abstract:
A method for identifying locations of one or more modules of an apparatus implemented in a vehicle for monitoring operation of at least one wheel of the vehicle includes steps of (a) communicating with one or more modules of the apparatus for receiving their identification codes at a processing arrangement of the apparatus, the one or more modules being mounted on at least one wheel of the vehicle; (b) driving the vehicle around a curved trajectory as sensed by the steering sensing arrangement and recording a direction of steering of the vehicle together with a temporal record of the physical parameter measured by the one or more modules together with their corresponding identification codes, the physical parameter pertaining to one or more tires of the at least one wheel; and (c) applying an analysis to the steering direction and the temporal record in respect of time to identify where the one or more modules are located on the at least one wheel of the vehicle, the analysis utilizing a characteristic that tires on an outside of the curved trajectory will experience a different peak values in the temporal record of the physical parameter than tires on an inside of the curved trajectory, and tires towards a front region of the vehicle experience a change in the temporal record of the physical parameter before and/or at a higher rate than tires towards a rear region of the vehicle for a forward direction of travel of vehicle.
