Abstract
Described is a procedure for controlling the transmission operation of a tire pressure monitoring device () arranged in a pneumatic tire of a vehicle, whereby data telegrams are transmitted in a normal mode of operation () in first time intervals, and there is a changeover from the normal mode of operation () to a pressure drop mode, if an inspection of the pressure signals indicates a drop in the pressure of a drop speed exceeding a pre-defined threshold value, and data telegrams are transmitted in the pressure drop mode in second time intervals, which are shorter than the first time intervals, and the tire pressure monitoring devices () are put into a travel starting mode () at the beginning of the travel by activation a roll sensor. Data telegrams are transmitted in the travel starting mode in shorter third time intervals as compared to the normal mode of operation.
