Abstract
A power train control system for a mobile machine is disclosed. The power train control system has a power source configured to produce a power output, a transmission device operatively connected to receive the power output and propel the mobile machine, and a control module. The control module is configured to receive an indication of a power demand, receive an indication of a current travel speed of the mobile machine, and reference the power demand and the current travel speed with a power train efficiency map to determine a desired power source speed. The power train control system is also configured to control operation of the transmission device to bring a speed of the power source within a predetermined amount of the desired power source speed.
