A METHOD OF CALCULATING TIRE COLD INFLATION PRESSURE IN A MOVING VEHICLE AND SYSTEM FOR SAME

摘要

The present invention relates to a system and method for determining more accurately a cold tire inflation pressure of at least one tire on a vehicle. The present invention provides a system for determining a cold inflation pressure value of a tire mounted on a vehicle, by recording an internal pressure reading of the tire while in motion, and adjusting the reading to take into account the altitude at which the reading took place, the difference between the internal temperature of the tire and the ambient temperature and the pressure change due to volume expansion and increase in the number of molecules as determined by the tire's characteristics such as tire brand, tire model, wheel size, tire profile, sidewall elasticity and tire air humidity. The present invention is advantageous in that the present invention is able to continuously generate accurate cold inflation pressure values for each tire of a vehicle in motion.
