Patent ID: 7942048

Claim:
A system for the determination of the pressure in a pneumatic vehicle tire which is mounted on a vehicle and or the speed of the vehicle, comprising: an array of load sensors which supplies force signals for a two-dimensional pattern of the distribution of force which is exerted by the vehicle tire in contact with the sensors when the vehicle moves over the array; a computer which is programmed so that it determines the tire pressure and/or the speed on the basis of the distribution of force independently of the method of manufacture or the model of the tire and or the vehicle; and a device for displaying the pressure and/or the speed; wherein the array comprises load sensors in at least two rows of load sensors which are arranged one behind the other in the direction of travel, whereby at least one row of load sensors is offset with respect to one or more rows of load sensors by a predetermined amount transverse to the direction of travel, and wherein a computer unit is adapted to perform a differential analysis of the leading edge of the force signals to detect and compensate for tread effects of the tire.
