Abstract

A first tire pressure sensor module is configured to provide information related to a pressure of a tire of a vehicle and comprises a pressure sensor configured to determine the information related to the pressure of the tire. The pressure module further includes a controller configured to selectively operate the tire pressure sensor module in an active state and in an inactive state, wherein an energy consumption of the tire pressure sensor module is lower in the inactive state than in the active state. The controller is further configured to control an output of the information related to the pressure of the tire in the active state, and operate the tire pressure sensor module in the inactive state based on determining that information related to a velocity of the tire indicates a velocity above a threshold.

First claim

What is claimed is:

1. A tire pressure monitoring system, comprising:
a first pressure sensor device configured to transmit pressure information, when at a first location of a wheel and in a first rotation state of the wheel when installed therein; and
a second pressure sensor device configured to transmit pressure information, when at a second, different location of the wheel and in a second, different rotation state of the wheel when installed therein.

2. The tire pressure monitoring system of claim 1 , wherein the first pressure sensor device and the second pressure sensor device are both configured to transmit pressure information to an electronic control unit.

3. The tire pressure monitoring system of claim 1 , wherein the second pressure sensor device is powered by an energy harveter.

4. The tire pressure monitoring system of claim 1 , wherein the first rotation state of the wheel is a first velocity range of the wheel, and wherein the second, different state of the wheel is a second, different velocity range of the wheel, wherein the first velocity range is lower than the second velocity range.

5. A wheel for a vehicle comprising a tire monitoring system according to claim 1 .

6. The wheel of claim 5 , wherein the first pressure sensor device is configured to provide information related to a tire pressure in a first lower velocity range of the wheel and wherein the second pressure sensor module is configured to provide information related to a tire pressure in a second higher velocity range.

7. The wheel of claim 6 , wherein the first velocity range of the wheel starts at or above zero velocity.
