Abstract
In the automotive industry that there is an increasing need for automatic tire pressure checking systems. One challenge here is to identify the positions of the tires on the vehicle. This is normally programmed-in it at the factory at the end of the production line. The tires however mostly do not remain in the same position during their lifetime. The invention allows a wheel unit to be automatically assigned to its wheel position on the motor vehicle. To this end the attenuation along a transmit path from a wheel unit to a transmission unit or receiving unit on the motor vehicle is determined. The attenuation determined is a characteristic value which allows conclusions to be drawn about the position of a wheel unit. An assignment by way of the attenuation has the advantage that the wheel unit is independent of variations in the transmit power of the transmission unit.
