Overload protection systems and methods are provided for controlling the amount of energy delivered to the drivetrain of work vehicles including axles, transmission, and other components thereof including for vehicles using power boost. A sensor in operative communication with a primary power equipment unit driving a transmission of a work vehicle generates a torque signal representative of torque delivered to the transmission by the primary power equipment unit. The overload protection method and system uses the torque signal to control the torque delivered to the transmission of a work vehicle by the primary power equipment unit.

Drivetrain overload protection for work vehicles using power boost

A work vehicle includes an engine; at least one continuously variable power source (CVP) configured to operate according to a commanded torque; an output shaft; a transmission positioned operatively between the output shaft and the engine and the CVP such that the output shaft selectively receives power from one or both of the engine and the at least one CVP; and a prognostics system configured to monitor a respective component associated with at least one of the output shaft or the transmission. The prognostics system includes a prognostics controller having a processor and memory architecture, configured to: receive input data, including the commanded torque; generate a usage value for the respective component for a time period as a function of the commanded torque; aggregate the usage value with previous usage values to generate a prognostics value over a life of the respective component; and store the prognostics value.

Work vehicle transmission prognostics system and method

Methods and systems are disclosed for reducing engine flywheel power reduction of an engine while protecting a drivetrain. The method includes monitoring transmission gear selection; determining reduction in flywheel power to protect the drivetrain; and monitoring engine power consumption by other engine power loads. When other engine power loads consume less power than the reduction in flywheel power to protect the drivetrain, the method includes reducing flywheel power by the power difference. When other engine power loads consume the same or more power than the reduction in flywheel power to protect the drivetrain, the method includes not reducing the flywheel power. Engine power can be consumed by both on-vehicle and off-vehicle power loads. Engine power can be consumed by an electric generator and/or a plurality of inverters, and their power consumption can be monitored. Information and commands can be communicated over a controller area network (CAN) bus.
