Method of identifying positions of wheel modules

Abstract

There is provided a method of identifying locations of modules () of an apparatus () for monitoring wheels () of a vehicle (). The sensor modules () operatively revolving with the wheels (). The modules () communicate with a processing arrangement (, ECU) of the vehicle (). The modules () sense a physical parameter of the wheels () and generate corresponding sensor signals for the processing arrangement (). The processing arrangement (, ECU) processes the sensor signals to compute information indicative of operation of the wheels (). The apparatus () also includes a sensor arrangement () for sensing an angular orientation () of the wheels (). The method includes steps of: (b) arranging an elongate feature () in an at least partially transverse direction relative to a direction of travel of the vehicle (); (c) driving the vehicle () over the elongate feature () to cause the wheels (), together with their associated modules (), to contact momentarily onto the elongate feature () and communicating signals including signal components stimulated by contact of the wheels () onto the elongate feature () to the processing arrangement (), the signals identifying a time at which their wheels () contacted onto the elongate feature () and identification codes (ID) of the modules (); and (d) from a temporal sequence of the signals received at the processing arrangement (), identifying whereat modules () are located on the wheels () of the vehicle ().
