Abstract

Allocates identifiers of units of a tire pressure monitoring system to the positions of ABS-sensors which are each assigned to the wheels of the vehicle. The identifiers are contained in signals that are emitted by the units. Each unit, which is called a wheel electronic, has a pressure sensor, which is sensitive to the tire pressure of the wheel, a motion sensor, which provides information on the rotation speed of the wheel, a memory with the individual identifier of the wheel stored therein, and a transmitter, which transmits signals only containing information on the rotation speed of the respective wheel, to a receiver. An evaluation device receives the transmitted identifier and compares the information on the rotation speed of the wheel transmitted along with the identifier, with rotation speed information, which were acquired by the ABS sensors for the same time span and transferred to the evaluation device.
