Claim:
1. A control system for a work vehicle hybrid power system to drive a powertrain, the hybrid power system including an internal combustion engine, a reversible shaft power conversion machine, and an energy storage device, the control system comprising: an engine controller, operatively coupled to the engine; a hybrid powertrain controller, operatively coupled to the engine controller and to the powertrain to control the reversible shaft power conversion machine and manage the energy storage level of the energy storage device; one or more sensors operatively coupled to the hybrid powertrain controller and the reversible shaft power conversion machine and the energy storage device, the hybrid powertrain controller configured to generate an available torque signal based on one or more signals from the one or more sensors and to generate a desired torque signal, both of which are received by the engine controller; wherein the engine controller generates a torque command signal configured to command the engine and the reversible shaft power conversion machine to operate at a commanded torque in response to the available torque signal and the desired torque signal from the hybrid powertrain controller.
