Method and device for monitoring the pressure in a tire
First Claim
Patent Images
1. A method of monitoring a pressure in a tire, which comprises:
- sensing a pressure prevailing in the tire or a temperature prevailing in the tire and outputting a sensor output signal based on the pressure or temperature;
determining a magnitude of change in the sensor output signal by comparing the sensor output signal with at least one threshold value; and
deciding whether the tire pressure is to be measured as a function of the magnitude of change in the sensor output signal.

Abstract
A tire pressure monitor and a method of measuring a pressure in a tire include a decision whether the tire pressure should be measured. The decision is made in dependence on a magnitude of a change in a signal which is output by a sensor which senses the pressure prevailing in the tire or the temperature prevailing in the tire. As a result it is possible to reduce the size and the weight of the components of a tire pressure monitor to be accommodated in the tire or in the rim to a minimum.

11. A device for monitoring a pressure in a tire, which comprises:
-
a sensor for sensing a pressure prevailing in the tire or a temperature prevailing in the tire, said sensor outputting a sensor output signal as a function of the prevailing pressure or temperature;
means for determining a magnitude of a change in the sensor output signal;
said means for determining the magnitude of the change in the sensor output signal being configured to determine the magnitude of the change by comparing the sensor output signal with one or more threshold values; and
means for deciding whether the tire pressure is to be measured as a function of the magnitude of the change in the sensor output signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
