Abstract:
Method for the coordination of identification signals, which are contained in signals which are emitted by transmitters in a tire pressure monitoring system, comprising the steps of;furnishing a tire pressure monitoring system including in each case a pressure sensor, a transmitter and a transmitter antenna at each one of a plurality of wheels of a vehicle, of one or several receiver antennas at the body of the vehicle and of a receiving and evaluation electronics connected through cables to the receiver antennas, to the positions of the wheels, at which wheels of the transmitters are disposed, capturing signals, which contain an identification signal, by one or several receiver antennas, transferring the signals to the receiver and evaluation electronics, and evaluating the signals relative to the identification signal in the receiving and evaluation electronics, measuring an acceleration resulting from the state of motion of the respective wheel at the monitored wheels in addition to the air pressure in the tire, signalizing a signal derived therefrom by way of the respective transmitter to the receiving and evaluation circuit, and evaluating an information contained in the track acceleration signal about the position of that wheel, from which wheel the track acceleration signal derives, and determining the sign of the track acceleration (b) occurring at the wheel already in an evaluation circuit disposed at the wheel during an acceleration phase after the start of the vehicle for distinguishing of wheels on the right hand side of the vehicle from wheels on the left hand side of the vehicle.
