A method for carrying out an assignment of the tire pressure control devices of a tyre pressure monitoring system to the wheel positions of a motor vehicle

摘要

The invention relates to a method for carrying out the assignment of the tire pressure control devices of a tyre pressure monitoring system to the wheel positions of a motor vehicle and a tire pressure monitoring system for carrying out the method. The tire pressure monitoring system contains an antenna system 2 consists of two antennas 4 and 6, which via a phase shifter 8 are coupled to each other, wherein, depending on the phase angle of the phase shifter 8 a of the antenna system 2, in a direction other has. The phase angle of the phase shifter 8, by means of the central processing unit 26 can be controlled, so that the receiving maximum in a targeted manner in the direction of a tire pressure control device can be aligned 32a to 32d. On the basis of the set phase angle φ is the central processing unit 26 this direction and assigns the corresponding tire pressure control device 32a to 32d of the wheel position, which in the previously determined direction is. The remaining tire pressure monitoring devices 32a to 32d their positions of the wheels are correspondingly associated.
