Abstract:
1. A method of identifying locations of one or more modules of an apparatus included in a vehicle for monitoring operation of at least a front set of wheels and a rear set of wheels of the vehicle, the sets of wheels including a left and a right wheel, the one or more modules operatively mounted to revolve with the sets of wheels, the one or more modules being operatively coupled in communication with a processing arrangement of the vehicle, the one or more modules being operable to sense at least one physical parameter of the wheel and to generate at least one corresponding sensor signal for the processing arrangement, the processing arrangement being operable to process the at least one sensor signal to compute information indicative of operation of the sets of wheels, wherein the method includes: (a) arranging for at least one elongate feature to be extending at a non-orthogonal inclined angle relative to a direction of travel of the vehicle; (b) driving the vehicle over the elongate feature to cause the sets of wheels, together with its associated one or more modules, to contact momentarily onto the elongate feature and communicating signals including signal components stimulated by contact of the sets of wheels onto the elongate feature to the processing arrangement, the signals identifying a time at which their wheels contacted onto the elongate feature and one or more identification codes of the one or more modules mounted onto the sets of wheels; and (c) from a temporal sequence of the signals received at the processing arrangement, identifying locations of the sets of wheels of the vehicle whereat the one or more modules are located, characterized in an additional step of identifying those one or more modules mounted to a wall or onto an inside rim of a tire of the at least one wheel by identifying periodic pulses in acceleration signal components derived from the one or more modules corresponding to rotation of the at least one wheel.
