Hybrid tire inflation monitor
First Claim
1. A method of monitoring inflation in a plurality of vehicle tires, the method comprising:
- determining a direct pressure in at least one primary tire;
determining a rolling radius for the primary tire and at least one secondary tire;
determining a pressure difference based on the determined rolling radius for the primary and secondary tires;
adjusting the determined pressure difference based on the determined direct pressure of the primary tire; and
comparing the determined pressure difference to at least one threshold value.

Abstract
The present invention provides a method, a computer usable medium including a program, and a system for monitoring inflation in a plurality of vehicle tires. The method and computer usable medium include the steps of determining a direct pressure in at least one primary tire and determining a rolling radius for the primary tire and at least one secondary tire. A pressure difference is determined based on the determined rolling radius for the primary and secondary tires. The determined pressure difference is adjusted based on the determined direct pressure of the primary tire. The determined pressure difference is compared to at least one threshold value. The system includes means for achieving the method steps of the invention.
