In a tire pressure measurement system a display indicating whether a tire (1) has an inadmissible or incorrect tire pressure and which tire (1) has inadequate tire pressure, is only activated when the driver stops to refuel. One or more sensors (6) are located near to the tank for this purpose and these identify a fuel stop.

The invention claimed is: 1. Device for measuring the tire pressure of any wheel on a vehicle with a tire pressure measurement device in each tire, each of which has sensors which measure the tire pressure directly or physical variables dependent on the tire pressure, an analysis unit in the motor
The invention claimed is: 1. Device for measuring the tire pressure of any wheel on a vehicle with a tire pressure measurement device in each tire, each of which has sensors which measure the tire pressure directly or physical variables dependent on the tire pressure, an analysis unit in the motor vehicle, which communicates in a wireless fashion with the tire pressure measurement devices, by means of which the measured tire pressure or the physical variables are sent to the analysis unit, in which it is determined whether the pressure in one or more tires is inadmissible or incorrect, which then causes a display signal to be generated; a display unit, by means of which an inadmissible or incorrect tire pressure is displayed to the driver by means of the display signal; wherein a sensor connected to the analysis unit provides the analysis unit an indication of whether a fuel stop has been made, as a result of which the display of the inadmissible or incorrect tire pressure is activated; and the sensor comprises an electromechanical sensor near the fuel cap which identifies an open filler neck or an open fuel compartment flap. 2. Device according to claim 1, wherein the sensor comprises a fuel level sensor, which provides the indication to the analysis unit. 3. A method for operating a tire pressure monitor system, comprising the steps of monitoring the tire pressure of any tire continuously, determining from the tire pressures measured whether the tire pressure is inadmissible or incorrect, identifying when a fuel stop occurs via monitoring for an open fuel compartment filler neck or an open fuel compartment flap, and in case of an inadmissible or incorrect tire pressure, generating a warning signal in response to the fuel stop. 4. A method according to claim 3, wherein the warning signal comprises a display message. 5. A method according to claim 3, wherein the warning signal comprises an acoustic message. 6. A method according to claim 3, wherein an identified inadmissible or incorrect tire pressure in at least one tire is displayed visually and wherein an identified fuel stop results in an acoustic message if the tire pressure is inadmissible or incorrect. 7. A method according to claim 3, wherein the respective wheel position of the tire or tires with an inadmissible or incorrect tire pressure is displayed. 8. A system for measuring the tire pressure of a wheel on a vehicle, said system comprising a tire pressure measurement device in each tire, each of which has sensors which measure the tire pressure, an analysis unit in the motor vehicle, which communicates in a wireless fashion with the tire pressure measurement devices, by means of which the measured tire pressure is sent to the analysis unit, in which it is determined using the measured variables whether the pressure in one or more tires is inadmissible or incorrect, which then causes a signal to be generated, a sensor connected to the analysis unit, said sensor identifies whether a fuel stop has been made and reports this to the analysis unit, as a result of which the inadmissible or incorrect tire pressure is signaled, and the sensor comprising is an electromechanical sensor, near to the fuel cap, which identifies an open filler neck or an open fuel compartment flap. 9. A system according to claim 8, further comprising a display for displaying said inadmissible or incorrect tire pressure. 10. A system according to claim 8, further comprising an acoustic output device for signaling said inadmissible or incorrect tire pressure. 11. A system according to claim 8, wherein the sensor comprises a fuel level sensor, which identifies when the vehicle is refueled.
