Described is a procedure for controlling the transmission operation of a tire pressure monitoring device (1) arranged in a pneumatic tire of a vehicle, whereby data telegrams are transmitted in a normal mode of operation (13) in first time intervals, and there is a changeover from the normal mode of operation (13) 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 (1) are put into a travel starting mode (10, 11, 12) 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. According to the invention, after the changeover into the travel starting mode (10), the process of transmitting a data packet consisting of several data telegrams will start, and a check will be conducted at least once after transmitting the first part of a data packet to determine whether the roll sensor (1b) continues detecting a turning of the wheel (11), and if not, the process of transmission of the data packet will be interrupted (14), whereby the process of transmission of the data packet shall be resumed (12) if the roll sensor (1b) is re-activated within a pre-defined time span (tC1) and the process of transmission of the data packet shall be started all over again (10) if the roll sensor (1b) is re-activated only after the lapse of the pre-defined time span (tC1) and there is a changeover to the normal mode of operation (13) after the complete transmission of the data packet.
