Abstract
Abstract A vehicle tire pressure monitoring system includes a pressure sensor, a transmitter, and a transmitting antenna at each of N wheels of the vehicle, and at least one receiving antenna attached to the vehicle, respectively allocated to each transmitting, antenna. The receiving, antenna is connected to an electronic receiving, and analysis system which determines whether a signal belongs to the local vehicle by allocating an identifier characterizing the individual wheel to its transmitter. Emitted signals contain the identifier and are forwarded to the central electronic receiving and analysis system, which records the signal intensities under the signal's identifier, compares the intensities, selects those N transmitter identifiers with the greatest intensities, then stores the N transmitter identifiers as belonging to the vehicle.

Total Claims: 12
Claim 1
Independent Claim
291 words
A method for allocating to a vehicle, transmitters of a tire pressure monitoring system which includes a respective pressure sensor, a transmitter, and a transmitting antenna at each of N wheels of the vehicle, at least one receiving antenna respectively allocated on a body of said vehicle to be monitored, and an electronic receiving and analysis system, each of said N wheels includes an identifier which characterizes the individual wheel to the respective transmitter, associated at said wheel so that each respective transmitter emits signals containing the identifier, which signals are forwarded to the central electronic receiving and analysis system, the method comprising the steps of: recording an intensity of each of the signals transmitted from the various transmitters to the receiving antenna, in conjunction with the transmitted signal identifier; comparing the intensities of the signals having different identifiers received by one and the same receiving antenna, wherein multiple successively received signals having the different identifiers are taken into account in the intensity comparison; selecting the N transmitter identifiers with the relatively greatest intensities received at the receiving antenna; and storing the N transmitter identifiers in the central electronic receiving and analysis system as belonging to the vehicle to be monitored; establishing in the electronic analysis system a list when the vehicle has only a single receiving antenna, and a matrix when the vehicle has a multiplicity of receiving antennas; assigning each of the list places and each of the matrix cells to a combination of a specific receiving antenna and a specific identifier contained in the received signals; and incrementing a value of the list place or the value of the individual matrix cell when a maximum intensity is recorded for the relevant combination of transmitter identifier and receiving antenna.

Independent Claim
291 words
A method for allocating to a vehicle, transmitters of a tire pressure monitoring system which includes a respective pressure sensor, a transmitter, and a transmitting antenna at each of N wheels of the vehicle, at least one receiving antenna respectively allocated on a body of said vehicle to be monitored, and an electronic receiving and analysis system, each of said N wheels includes an identifier which characterizes the individual wheel to the respective transmitter, associated at said wheel so that each respective transmitter emits signals containing the identifier, which signals are forwarded to the central electronic receiving and analysis system, the method comprising the steps of: recording an intensity of each of the signals transmitted from the various transmitters to the receiving antenna, in conjunction with the transmitted signal identifier; comparing the intensities of the signals having different identifiers received by one and the same receiving antenna, wherein multiple successively received signals having the different identifiers are taken into account in the intensity comparison; selecting the N transmitter identifiers with the relatively greatest intensities received at the receiving antenna; and storing the N transmitter identifiers in the central electronic receiving and analysis system as belonging to the vehicle to be monitored; establishing in the electronic analysis system a list when the vehicle has only a single receiving antenna, and a matrix when the vehicle has a multiplicity of receiving antennas; assigning each of the list places and each of the matrix cells to a combination of a specific receiving antenna and a specific identifier contained in the received signals; and incrementing a value of the list place or the value of the individual matrix cell when a maximum intensity is recorded for the relevant combination of transmitter identifier and receiving antenna.
Claim 3
Dependent Claim
54 words
The method as defined in claim 1 , incrementing the value by which a number of events which are assigned to a specific combination of receiving antenna and identifier when a further event occurs, or incrementing the content of a matrix cell or a list place, which is weighted as a function of intensity.
Claim 4
Dependent Claim
62 words
The method as defined in claim 2 , setting the values in the matrix cells and the list places at specific time interval to a fixed value Ds for transmitters allocated to the vehicle and setting the values in the list places to zero for transmitters not allocated to the vehicle, said Ds defining a time after which the allocation is checked.
Claim 5
Dependent Claim
