Patent ID: 7876206

Claim:
A procedure for wireless transmission between a wheel module ( 9 ) arranged in a tire ( 2 ) and a control device ( 3 ; 28 ) arranged outside the tire ( 2 ), the method comprising: transferring a first transmission signal (S 1 ) from an antenna ( 6 ) of the control device ( 3 ; 28 ) to an antenna ( 11 ) of the wheel module ( 9 ); transmitting data via a second transmission signal (S 2 ) from the wheel module ( 9 ) to the control device ( 3 ; 28 ), wherein a different frequency is provided for the first transmission signal (S 1 ) than for the second transmission signal (S 2 ); receiving by the antenna ( 11 ) of the wheel module the first transmission signal (S 1 ), during a coupling period (TK) within which when the tires ( 2 ) are rotating, an also rotating sphere of influence ( 15 ) of the antenna ( 11 ) of the wheel module ( 9 ) and a stationary sphere of influence ( 14 ) of the antenna ( 6 ) of the control device ( 3 ; 28 ) partially overlap; and recognizing a beginning of the coupling period (TK) is recognised by the wheel module ( 9 ), wherein the transmission of data from the wheel module ( 9 ) to the control device ( 3 ; 28 ) is started after the coupling period (TK) begins, wherein a speed of the tire ( 2 ) or a size which is proportional to it is recorded and compared with a speed threshold value, and the second transmission signal (S 2 ) can be transmitted with an extended data telegram in particular only when the speed threshold value is not reached.
