1. An apparatus for controlling a powered device comprising:
- an engine;
a motor/generator;
an ECM operably coupled to the engine and the motor/generator and configured to;
determine whether the powered device is experiencing a cyclical load profile including high load conditions and low load conditions; and
respond to the powered device experiencing a cyclical load profile by applying a first power component to the powered device using the engine, the first power component corresponding to an average power required by the powered device during the cyclical load profile, and applying a second power component to the powered device using the motor/generator, a sum of the first power component and the second power component corresponding to a power required by the powered device during the high load conditions.

Abstract
A method of controlling operation of a powered device is provided, comprising determining whether the device is experiencing a cyclical load profile including high load conditions and low load conditions, applying a first power component to the device using an engine, the first power component corresponding to an average power required by the cyclical load profile, and applying a second power component to the device using a motor/generator, a sum of the first power component and the second power component corresponding to a power required by the powered device during the high load conditions.

9. A method of controlling operation of a powered device, comprising:
-
determining whether the powered device is experiencing a cyclical load profile including high load conditions and low load conditions; applying a first power component to the powered device using an engine, the first power component corresponding to an average power required by the powered device during the cyclical load profile; collecting power generated by the engine in excess of a power required by the powered device during the low load conditions; storing the collected power in an energy storage device; and applying a second power component to the powered device using a motor/generator, a sum of the first power component and the second power component corresponding to a power required by the powered device during the high load conditions; wherein applying the second power component by a motor/generator occurs in response to the power required by the powered device during the high load conditions exceeding the first power component. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of controlling operation of a powered device, comprising:
-
determining whether the powered device is experiencing a cyclical load profile including high load conditions and low load conditions; applying a first power component to the powered device using an engine, the first power component corresponding to an average power required by the powered device during the cyclical load profile; collecting power generated by the engine in excess of a power required by the low load conditions; storing the excess power in an energy storage device; applying a second power component to the powered device using a motor/generator in response to the first power component being less that a power required by the powered device during the high load conditions; and responding to a drift in a state-of-charge (“
SOC”
) of the energy storage device by adjusting the first power component. - View Dependent Claims (18, 19, 20)
