Abstract
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.
