摘要

A device for determining the position of the centre of each wheel (1-4) of a vehicle relative to the portion of the body of the vehicle vertically above each respective wheel. Sensors (6-9) are arranged on the body of the vehicle and provide signals to a computer (14) representative of the said relative positions. The computer (14) generates a time-average of the relative position of each wheel (1-4). The displacement of the time-averaged relative position of one wheel of the vehicle from a plane (13) defined by the aforementioned relative positions of three of the other wheels of the vehicle, is determined by the device. Should the time-averaged position of the one wheel deviate excessively from plane (13) a warning signal is issued to the driver via warning display (16). Such a warning signal would be issued in the event of a sufficient drop in pressure in the tyre associated with the aforementioned one wheel i.e. the drop in pressure and resulting tyre deflation causing a displacement of the wheel (1 of Fig. 2) from the plane defined by any three of the other wheels, each of the latter having fully inflated tyres.
