International Classification:

G06F 7/00
G06F 19/00
G05B 13/02
F02D 7/00

US Classification:

701 62, 701 99, 701102, 701110, 701 50, 700 29, 702 41, 12339919, 12340623, 123436, 123478

Abstract:

A torque estimator is disclosed for estimating torque on a machine. A computer system may include a torque estimator module located on the machine. The torque estimator module may be configured to receive a plurality of engine parameters, receive a drivetrain component parameter, determine an estimated torque value at the drivetrain component based on the plurality of engine parameters and the drivetrain component parameter. The computer system also may include an analysis module located on the machine. The analysis module may be configured to receive the estimated torque value and the drivetrain component parameter, and update a histogram data structure based on the estimated torque value and the drivetrain component parameter. The analysis module may also be configured to evaluate the histogram data structure in order to determine if excessive torque is being applied to a drivetrain component.

US Classification:

705 712, 701 344

Abstract:

A method is disclosed for using information related to the service history of a power-train component. The method may include using a machine-management system with at least one information processor to acquire information related to loads experienced by the power-train component during a first period, the first period occurring before a disassembly procedure involving disassembly of the power-train component from a power train. The method may also include employing the machine-management system and the acquired information related to loads experienced by the power-train component during the first period to perform one or more tasks in connection with use of the power-train component after the disassembly procedure.
