1. A power train, comprising:
- a power source for generating a power output;
a power storage device for storing and distributing power; and
a controller configured to cause the distribution of power from the power storage device for assisting the power source when the rate of fuel entering the power source is above a threshold fuel rate, the threshold fuel rate being a fuel rate at which, assisting the power source increases the efficiency of the power train.

Abstract
A power train is provided having a power source for generating a power output. The power train also has a power storage device for storing and distributing power. The power train further has a controller configured to cause the distribution of power from the power storage device for assisting the power source when the rate of fuel entering the power source is above a threshold fuel rate. The threshold fuel rate is a fuel rate at which, assisting the power source increases the efficiency of the power train.

9. A method for operating a power train, comprising:
-
sensing a first parameter indicative of a rate of fuel entering a power source; sensing a second parameter indicative of an amount of power generated by the power source; and distributing power from a power storage device to assist the power source when the rate of fuel entering the power source is above a threshold fuel rate, the threshold fuel rate being a fuel rate at which, assisting the power source increases the efficiency of the power train. - View Dependent Claims (10, 11, 12, 13)

14. A method for operating a power train, comprising:
-
receiving an input from an operator requesting a desired power output; sensing a first parameter indicative of a rate of fuel entering a power source; sensing a second parameter indicative of an amount of power generated by the power source; sensing a third parameter indicative of an amount of power stored in a power storage device; and distributing power from the power storage device when the amount of power stored in the power storage device is greater than the difference between the amount of power currently being generated by the power source and the desired power output, and the fuel rate is above a threshold fuel rate, the threshold fuel rate being a fuel rate at which, assisting the power source increases the efficiency of the power train. - View Dependent Claims (15, 16, 17, 18, 19, 20)
