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.

Efficiency based integrated power train control system

A vehicular powertrain system includes a prime mover having an output, a multi-ratio transmission having an input, and a torque reduction coupling system coupling the prime mover output and the multi-ratio transmission input. The exemplary torque reduction coupling system includes a clutch and a planetary gear set selectively coupling the prime mover output to the multi-ratio transmission input. The exemplary planetary gear set includes one components of the planetary gear set being selectively coupled to the clutch.
