GPS (global positioning system) based method for determining a change of an inflation pressure of a tire and system therefor

The present invention relates to a method for determining a change of a tire inflation pressure, comprising the steps of determining a first traveled distance d1 of the tire of the vehicle by using a first calculation method, determining a second traveled distance d2 of the tire of the vehicle by using a second calculation method, and calculating the difference between d1 and d2, as well as to a system for determining a change of a tire inflation pressure comprising a first means for determining a first traveled distance d1 of the tire of the vehicle by using a first calculation method, a second means for determining a second traveled distance d2 of the tire of the vehicle by using a second calculation method, and a calculation unit for calculating the difference between d1 and d2.
