Abstract

A monitoring system includes sensors, clocks, global positioning systems (GPS) receiver, display screens and a controller circuitry. The controller circuitry is configured to analyze the collected signals, the time information, and the route information to identify at least one trigger factor based on a tire characteristic; determine whether the identified at least one triggering factor exceeds an triggering threshold based on the collected signals and information; derive when the identified triggering factor exceeds the triggering threshold, an triggering priority indicating an order in which the triggering factors are processed based on the collected signals and route information; trigger a tire monitoring procedure based on the collected information, the triggering threshold and the triggering priority; and display at the display screen, results of the tire monitoring procedure to provide a visual indication of the tire characteristic that caused the triggers factor to exceed the triggering threshold.

3. The method of claim 2, further comprising setting with the controller circuitry the triggering threshold based on a function of temperature, time, sun-light condition, and route information.

4. The method of claim 1, wherein the controller sets the triggering priority as a function of the collected signals, the time information and the route information.

5. The method of claim 1, wherein the controller circuitry provides a warning when a projected GPS route indicates a terrain that is inappropriate for a present condition of the tire.

6. The method of claim 1, wherein the sensor includes at least one of a pressure sensor, a wireless sensor, a temperature sensor, and a light sensor.

7. The method of claim 1, wherein the wireless sensor is configured to determine a distance between two tires and includes a transceiver, and a distance sensor.
