Torque estimator for a machine
First Claim
1. A computer system for monitoring a drivetrain component of a machine, the computer system comprising:
- a torque estimator module disposed on the machine and 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; and
an analysis module disposed on the machine and configured to;
receive the estimated torque value from the torque estimator module and receive the drivetrain component parameter;
update a histogram data structure based on the estimated torque value and the drivetrain component parameter; and
evaluate the histogram data structure in order to determine whether the drivetrain component is experiencing an excessive torque corresponding to a value of the histogram data structure exceeding a threshold.

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.
