System and method for controlling torque load of multiple engines

摘要

A method of controlling torque load of multiple engines according to a torque distribution algorithm includes determining a combined torque output value responsive to actual torque outputs of first and second engines. A desired torque output for the first engine is determined responsive to a first desired contribution portion of the combined torque output value, and a desired torque output for the second engine is determined responsive to a second desired contribution portion of the combined torque output value. A torque error for each of the first and second engines is determined responsive to a difference between the desired torque output for a respective one of the first and second engines and the actual torque output from the respective engine. Operation of each of the first and second engines is controlled responsive to the respective torque error.

1. A method of controlling torque load in a machine having a front portion pivotally connected to a rear portion, the front portion and the rear portion each including an engine and a powertrain, comprising:
executing a torque distribution algorithm on an electronic controller, including:
determining a combined torque output value responsive to a first actual torque output of a first engine associated with a dual powertrain machine;determining a second actual torque output of a second engine associated with the dual powertrain machine, wherein the dual powertrain machine includes separately operating electronically controlled transmissions;determining a first desired torque output for the first engine responsive to a first desired contribution portion of the combined torque output value;determining a second desired torque output for the second engine responsive to a second desired contribution portion of the combined torque output value;determining a first torque error for the first engine responsive to a difference between the first desired torque output and the first actual torque output;determining a second torque error for the second engine responsive to a difference between the second desired torque output and the second actual torque output;controlling operation of the first engine responsive to the first torque error; andcontrolling operation of the second engine responsive to the second torque error.
