To provide a method of determining the position of at least one tire/wheel assembly mounted on a vehicle.
This method comprises a step of simultaneously measuring the magnetic field of the earth by using at least two coils 131, 132 formed integrally with the wheel 20 of the tire/wheel assembly and tightened to a given side of the wheel. The two coils are so arranged that the projection images of the axes 141, 142 of the coils on a plane vertical to the rotating axis 60 of the tire/wheel assembly are tilted relative to each other. The method further comprises the steps of measuring a phase difference between the measured signals, determining the moving direction of the vehicle, and determining the side of the vehicle on which the tire/wheel assembly is positioned by using the sign of the phase difference of the vehicle and the moving direction.
