Method for associating tyre sensor modules (6.i) with a trailer vehicle of a driver's own commercial-vehicle/trailer combination, having at least the following steps: - capturing data messages from tyre sensor modules (6.i, 106.i, 206.i) in a monitoring region of a receiving module (401; 600); - associating the captured data messages with a tyre sensor module (6.i, 106.i, 206.i) (401; 601); - ascertaining a number (counter_p_ID.i, counter_d_ID.i) of captured data messages for each detected tyre sensor module (6.i, 106.i, 206.i) (403; 603, 610); - rating the captured data messages if the number (counter_p_ID.i, counter_d_ID.i) of captured data messages for at least one tyre sensor module (6.i, 106.i, 206.i) has reached a maximum counter (counter_max), in order to establish whether the tyre sensor modules (6.i, 106.i, 206.i) received in total up to then belong to the driver's own trailer vehicle or to the adjacent trailer vehicle (103, 203) (404; 604; 613); - accepting the tyre sensor modules (6.i) detected in the rating as affiliated to the driver's own trailer vehicle (404; 615), characterized in that each tyre sensor module (6.i, 106.i, 206.i) detects a wheel position (R.i) associated with the respective tyre sensor module (6.i, 106.i, 206.i) and a trailer axle configuration (AKonf), so that for an accepted tyre sensor module (6.i) the detected wheel position (R.i) and the detected trailer axle configuration (AKonf) can be taken as a basis for making a positional association on the driver's own trailer vehicle (405; 615) to allow tyre states (p, T, s) and/or tyre sensor module states of the driver's own trailer vehicle to be output on the basis of a fixed position. - capturing data messages from tyre sensor modules (6.i, 106.i, 206.i) in a monitoring region of a receiving module (401; 600); - associating the captured data messages with a tyre sensor module (6.i, 106.i, 206.i) (401; 601); - ascertaining a number (counter_p_ID.i, counter_d_ID.i) of captured data messages for each detected tyre sensor module (6.i, 106.i, 206.i) (403; 603, 610); - rating the captured data messages if the number (counter_p_ID.i, counter_d_ID.i) of captured data messages for at least one tyre sensor module (6.i, 106.i, 206.i) has reached a maximum counter (counter_max), in order to establish whether the tyre sensor modules (6.i, 106.i, 206.i) received in total up to then belong to the driver's own trailer vehicle or to the adjacent trailer vehicle (103, 203) (404; 604; 613); - accepting the tyre sensor modules (6.i) detected in the rating as affiliated to the driver's own trailer vehicle (404; 615), characterized in that each tyre sensor module (6.i, 106.i, 206.i) detects a wheel position (R.i) associated with the respective tyre sensor module (6.i, 106.i, 206.i) and a trailer axle configuration (AKonf), so that for an accepted tyre sensor module (6.i) the detected wheel position (R.i) and the detected trailer axle configuration (AKonf) can be taken as a basis for making a positional association on the driver's own trailer vehicle (405; 615) to allow tyre states (p, T, s) and/or tyre sensor module states of the driver's own trailer vehicle to be output on the basis of a fixed position.
