Abstract

The invention describes a method for allocating identifiers of wheel electronics of a tire pressure monitoring system to positions of wheels of a vehicle, the simultaneously occurring rotation speeds of the wheels, normalized on a consistently chosen rolling radius of the wheels differ during cornering because of the different positions of the wheels on the vehicle, so that the positions of the wheels can be sorted according to increasing speed of the wheels during cornering, the wheel electronics of each wheel comprising a pressure sensor, a motion sensor, a memory and a transmitter, which transmits signals to a receiver being connected to an evaluation device, which receives the transmitted identifiers and compares the distances which the corresponding wheels have traveled in a defined time span, sorts the identifiers according to the length of the distance traveled in the defined time span and allocates the identifiers to the wheel positions.
