ABSTRACT:
A method is provided for controlling power provided by a drive train system of a mobile machine, which includes an engine that provides engine power to a generator that, in turn, provides generator power to a motor. The motor provides ground power to a travel mechanism that enables the mobile machine to travel across a terrain surface. In one embodiment, the method includes adjusting operation of the motor based on a determined ground speed of the mobile machine. Based on the adjusted motor operations, the operation of the generator is adjusted. Also, the operation of the engine is adjusted such that the engine produces an amount of engine power that meets a load demand corresponding to the adjusted operation of the generator.
