Patent ID: 7024318

Claim:
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.
