Tire management system and method
First Claim
1. A method of managing a plurality of machines, comprising:
- receiving tire data associated with a tire sensor on a machine over a network, the tire sensor being associated with a tire on the machine and the tire data including at least one of tire temperature and tire pressure;
determining a tire load for the tire using one of a relationship between the tire load, the tire temperature, and ambient temperature, or a relationship between the tire load, the tire pressure, and ambient pressure;
comparing the tire load for the tire against a tire rating for the tire;
determining, based on the comparison, whether the tire rating will be exceeded on a current assignment; and
altering the current assignment of the machine in response to determining that the tire load will exceed the tire rating.

Abstract
A system for managing a plurality of machines is provided that includes a plurality of machines, each having a control module and a tire sensor associated with a tire on the machine. The tire sensor is configured to measure tire data including at least one of tire temperature and tire pressure. A worksite controller is in communication with each control module, and is configured to generate new travel paths for the machines and selectively communicate the new travel path to each control module. A central processor in communication with the worksite controller receives the tire data and uses it to determine a tire load for each tire, comparing the tire load against a tire rating and determining whether the tire rating will be exceeded. The worksite controller is further configured to alter the current assignment of at least one machine in response to the tire load.

9. A system for managing a plurality of machines, comprising:
-
a plurality of machines, each having a control module; a tire sensor associated with a tire on each of the plurality of machines, the tire sensor measuring tire data including at least one of tire temperature and tire pressure; a worksite controller in communication with each control module, the worksite controller configured to; generate a travel path for the plurality of machines between a first location and a second location; and selectively communicate the travel path to each of the control modules; a central processor in communication with the worksite controller, the central processor being configured to; receive the tire data and compare the tire temperature to a map of tire load versus tire temperature and ambient temperature to determine a tire load for each tire; compare the tire load for each tire against a tire rating; and determine whether the tire rating will be exceeded by the tire load on a current assignment, wherein the worksite controller is configured to generate a new travel path for at least one of the plurality of machines such that the tire rating will not be exceeded by the tire load. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of managing a plurality of machines, comprising:
-
receiving tire data associated with a tire sensor on a machine over a network, the tire sensor being associated with a tire on the machine and the tire data including at least one of tire temperature and tire pressure; determining a tire load for the tire using one of; a map relating tire load to the tire temperature and ambient temperature, or a map relating tire load to the tire pressure and ambient pressure, wherein tire load is a ton kilometer per hour (TKPH) value; comparing the tire load for the tire against a tire rating for the tire; and determining whether the tire rating will be exceeded by the tire load on a current assignment; and altering the current assignment of the machine in response to determining that the tire rating will be exceeded by the tire load. - View Dependent Claims (17)
