Abstract
Apparatus (4; 5) for checking the inflation pressure of a tire (3) of a vehicle (2) while the tire is being moved over the apparatus in a direction of travel (A). The apparatus comprises a base (7), a platform (8) which is mounted over the base, a first load sensor system (9) arranged between the platform and the base, and a second load sensor system (12) mounted on an upper surface of the platform and comprising a linear array of high resolution sensors (13, 25) extending across the platform. A data processing unit (6) processes data obtained by sampling the outputs of the first and second sensor system and provides an indication of the inflation pressure of the tire. The data obtained by sampling the output of the first sensor system may be used to determine the total load borne by the platform, and/or the direction of travel of the tire over the platform, and/or the speed of travel of the tire over the platform and/or the tracking angle of the vehicle tire. The data may also be used to determine a time interval during which data from the second sensor system is to be used to provide a representative sensor load value.
