Abstract
A tire pressure monitoring system as described herein leverages a real-time onboard vehicle mass estimate to determine whether tire pressure is appropriate for the current loading conditions. The system is suitable for use with vehicles having two or more placard tire pressures (with two or more corresponding tire loading capacities). The system can notify the driver to adjust the tire pressure to the proper placard tire pressure for the given load conditions, and/or initiate automatic inflation or deflation by an onboard tire inflation system.
