Method for Checking Tire Pressure in Real Time
First Claim
1. A method for real-time monitoring of tire pressure in a tire of a wheel of a vehicle, the method comprising the acts of:
- determining, via a pressure sensor configured in the tire, a pressure value;
transmitting, by an electronic wheel device and without use of a trigger transmitter fixed on the vehicle, the pressure value via radio in short transmission intervals to a monitoring device installed in the vehicle only if the pressure value is outside of a prespecified normal range at least when the vehicle is not moving;
transmitting, by the electronic wheel device and when the vehicle is not moving, a signal at certain time intervals, said signal being suitable for a system monitoring function and having a short transmission duration on an order of 25 μ
s to 500 μ
s, whereinthe electronic wheel device carries out a measurement of the tire pressure using a same time frame or a whole-number fraction or multiple thereof, of the certain time intervals.

Abstract
A method is provided for real-time monitoring of tire pressure, wherein the pressure value determined by use of a pressure sensor in the tire is transmitted by an electronic wheel device, without the use of a trigger transmitter fixed on the vehicle, by radio, in short transmission intervals, to a monitoring device installed in the vehicle, only if, at least when the vehicle is not moving, the value is outside a prespecified normal range. When the vehicle is not moving, the electronic wheel device transmits a signal suitable for a system monitoring function, at certain time intervals and, using the same time frame or a whole-number fraction or multiple thereof, carries out a measurement of the tire pressure. The signal has a short transmission duration on the order of 25 μs to 500 μs.
