Method and device for allocating triggered transmitters of a tire monitoring system, especially of a tire-pressure monitoring system
First Claim
1. Method for allocating first transmitters of a tire monitoring system, said tire monitoring system comprisinga wheel unit comprising a sensor, a first transmitter, which can be triggered, and a sending antenna on each of N wheels arranged on L axles of a vehicle according to a predetermined axle formula,at least one receiving antenna on the vehicle body associated to the first transmitters andan electronic receiver and evaluation system, connected to the at least one receiving antenna by allocating an identifier characteristic of a particular wheel to its respective first transmitter, by emitting data telegrams, which contain the identifier, in response to a triggering action of second transmitters which serve as trigger transmitters, and by passing on such data telegrams to the electronic receiver and evaluation system,wherein the number n of the trigger transmitters arranged on the vehicle is smaller than the number A of the axle positions,comprising the steps ofassociating each axle position of the vehicle to a triggering range of at least one of the n trigger transmitters,arranging and/or configuring the trigger transmitters so that at least one axle position is associated to the triggering range of at least two trigger transmitters,defining the triggering range of each trigger transmitter in such a manner that a number of x axle positions is arranged within the triggering range,wherein the same number of axle positions is provided in each triggering range of each trigger transmitter,registering the identifiers of the electronic wheel units that respond to a trigger signal of a particular trigger transmitter by the at least one receiving antenna and are passed on to the electronic receiver and evaluation unit, and calculating the axle position of a given electronic wheel unit based on the axle formula of the vehicle.

Abstract
Allocating first transmitters of a tire monitoring system, especially of a tire-pressure monitoring system having a wheel unit comprising a sensor, a first transmitter, which can be triggered, and a sending antenna on each of N wheels arranged on L axles of a vehicle according to a predetermined axle formula, further having receiving antenna on the vehicle body associated to the first transmitters and an electronic receiver and evaluation system, connected to receiving antenna by allocating an identifier characteristic of a particular wheel to its respective first transmitter, by emitting data telegrams, which contain the identifier, in response to a triggering action of second transmitters, and passing on such data telegrams to the central electronic receiver and evaluation system. The number n of the trigger transmitters is smaller than the number A of the axle positions, that each axle position is associated to a triggering range of n trigger transmitters.
